Description

BACKGROUND OF THE PRESENT INVENTION

FIELD OF INVENTION

[0001] The present invention relates to the field of conveyance illumination, and more particularly to a headlamp and a lighting system integrating high and low beams and the low and high beam illumination method provided thereby.

DESCRIPTION OF RELATED ARTS

[0002] Headlamps, also called headlights, are mounted on two sides of the head of a vehicle such as a car for night illumination. Due to the lighting effect of the headlamps directly affects the operation and traffic safety of driving at night, the traffic management departments of various countries in the world have prescribed their lighting standards in legal form. With the continuous development of technology, the past incandescent vacuum lamps have been eliminated, and now the headlamps of automobiles are mainly halogen lamps and xenon lamps.

[0003] Conveyance headlamps, such as car headlamps, have their own light distribution structure. Conveyance headlamps can be classified into high beam lamps and low beam lamps depending on the type of light. For example, after being reflected by a lampshade reflector, the light emitted by the high beam lamps is directed straight forward to form a "high beam." The light emitted by the low beam lamp is blocked to the upper half of the lampshade reflector by a visor, and the reflected light is diffused downward toward the ground to form a "low beam", so as the prevent bringing dazzle or glare to the driver of the opposite vehicle.

[0004] For headlamps, there are very strict requirements for the distribution of low beam illumination. Take a low beam lamp on a right driven car as an example. Referring to Fig. 1A and Fig. 1B, according to some light distribution standards, when the headlamps are in low beam mode, on the vertical light distribution screen, the bright area below the h-h' line needs to reach a certain light intensity, and the upper side of the HH is a dark area. B50L indicates the driver's eye position of the vehicle 50 meters away from the headlamps above the opposite lane. The light intensity at the position indicated by B50L is required to be below 650 cd to avoid dazzle caused by excessive light intensity. The area below the left HH is the main illumination area. The 15°diagonal line or the 45° diagonal line on the right side and the horizontal line which is 25cm far away from the horizontal plane define a bend line HH→HH1→H1H2→H2H4. The upward side of the bend line HH→HH1→H1H2→H2H4 is the dark area, and the lower side of the bend line HH→HH1→H1H2→H2H4 is the side high illumination area and the main illumination area. The right side high illumination area provides the driver with right side road lighting and road sign illumination, and at the same time sets the maximum light intensity requirement of the BR point to avoid traffic safety accidents caused by dazzle of pedestrians approaching the vehicle.

[0005] At the same time, there is a certain brightness requirement in the Zone III area above the cut-off line, so as to ensure that there is sufficient brightness in the front upper part of the vehicle, so that the pedestrians in front of the vehicle and the driver on the opposite side know the existence of the vehicle, as shown in Fig. 1C. Therefore, P1+P2+P3≥190cd, p4+P5+P6≥375cd, P7≥65cd, P8≥125cd are specified. At the same time, the pedestrians in front of the vehicle and the driver of the opposite vehicle cannot be dazzled, that may cause traffic accidents. Therefore, the maximum value at each point from P1 to P8 cannot be more than 625 cd.

[0006] As a new light source, LED has many advantages that other illumination sources do not have, such as low voltage, long life, small size, light weight, fast response, no radiation, no pollution and resistant to various harsh conditions, and the LED illumination direction is single-sided (the traditional light source is 360° in volume), which is more conducive to the collection and utilization of light and the utilization of light is improved. Therefore, it is also a new trend to make LED headlamps for LEDs. However, the luminous flux of the existing LED is not high. In order to increase the luminous flux, it is necessary to increase the current, resulting in a large amount of heat generation, a large heat dissipation volume, and a reduced life. At present, LED low beam lamps are already in use on the market, but the LED luminous flux is insufficient. In order to meet the standard, the brightness in the middle area is higher, and the brightness on the left and right sides is significantly reduced, resulting in a narrow visual width of the driver. At the same time, the brightness of HID headlamps on the market is brighter than that of LED headlamps. Many auto manufacturers are reluctant to reduce the brightness requirements to choose LED headlamps, unless the LED headlamps can reach the brightness level of HID headlamps and the power consumption is lower than HID headlamps, no more than 25W, so in order to completely replace HID headlamps, LED headlamps must be optimized from the brightness, power, heat dissipation, total LED lamination flux and optical system of the lamps. The existing optical system is difficult to meet the requirements.

[0007] Fig. 2 is a schematic structural view of a conventional LED high-low lamps integrated system, including an ellipsoid reflector 201, a shielding screen 202, and a lens 203. According to the geometric properties of the ellipsoid, it has two focal points F1 and F2. The LED light source is placed on one of the focal points F1, and the light beam emitted by the LED light source is reflected by the ellipsoidal reflector 1 and concentrated on another focus F2, and the second focus of the ellipsoid is precisely the focus of the lens. According to the nature of the lens, the light emitted from the focus is refracted through the lens, and the output should be parallel lights. According to this principle, the shape of the ellipsoid, or the shape of the lens 203, can be appropriately changed as required, for the purpose of horizontally diffusing the light from the lens, and then the shading screen 202 is placed at the focus of the lens to form a low beam lamp which has a bend line extends upwardly with 45°angle with respect to the horizontal line and extends to the horizontal direction at the position where the vertical distance is 25 cm, and the cut-off line of the horizontal line of the other side. By removing the shading screen, the ellipsoidal light of the lower portion of the LED module passes through the focus of the lens 203 to form a high beam. Since the conventional LED headlamp adopts an ellipsoidal surface, only one LED module can be placed at the focal point F1. One LED module has a small luminous flux. In order to increase the luminous flux, it is necessary to increase the LED current, resulting in a large amount of heat generation, a large heat dissipation volume, and a reduced life. At the same time, the LED is placed horizontally in the middle of the upper and lower positions, and the heat needs to be diffused to the external heat sink through a small intermediate heat piece, and the heat dissipation effect is poor.

[0008] Fig. 3A and Fig. 3B are schematic structural diagrams of the another LED high-low lamps integrated system which includes a low beam LED 301, a high beam LED 302, a low beam light distribution lens 303, a high beam light distribution lens 304, etc. The light from the LED 301 directly passes through the low beam light distribution lens 303 to form a low beam lamp which has a left and right symmetrical spot. The light from the LED 302 directly converges through the high beam light distribution lens 304 to form a high beam spot. The light distribution lens has a small optical wrap angle, and all the light outside the wrap angle is wasted, the light utilization efficiency is low, and cannot be used as the low beam lamps of the left driving rule or the right driving rule cannot be made, of the low beam.

[0009] Fig. 4 illustrated a structural perspective view of the a lighting system integrating high and low LED beams having a turtle-form reflector, which comprises a low beam lamp LED 401, a high beam lamp LED 402, a low beam lamp reflector 403, a high beam lamp reflector 404, a condenser lens 405, a low beam lamp cut-off line screen plate 406, and a heat dissipation body 407. The LED is placed close to the heat sink 407 to facilitate heat dissipation. The light of the LED 401 is reflected by the reflector 403, and then refracted by the condenser lens 405, and the light above the cut-off line is shaded by the cut-off shield 406 to form a low-beam spot. The light of the LED 402 is reflected by the reflector 404 to the focus of the condenser lens 405, and then refracted by the condenser lens to form a high beam spot. The LED of this optical system can only use one LED module, so that the total luminous flux of the LED is limited, and the volume is limited, and the optical subtended angle of the reflector is small, and the light outside the wrap angle cannot be collected and utilized, so that the light utilization efficiency is low.

[0010] Fig. 5A illustrated a structural perspective view of the a lighting system integrating high and low LED beams having a dome reflector, which comprises five low beam lamp LED 501, three high beam lamp LED 502, a low beam lamp reflector 503, a high beam lamp reflector 504, a condenser lens 505, a low beam lamp cut-off line screen plate 506, and a heat dissipation body 507. With multiple LEDs dispersed, the total luminous flux of the LED is improved and the heat dissipation is facilitated, but a rotating dome reflector can only correspond to one LED, so the number of LEDs is limited, and the dome-shaped reflector corresponding to each LED has few faces. Most of the faces are cut off and the light utilization efficiency is medium.

[0011] FIG. 5B is a schematic structural diagram of a TIR lens LED low beam system, which includes 10 LEDs 601, 10 TIR assemblies 602, a condenser lens 603, a visor 604, and a heat sink 605. By using a plurality of scattered LEDs, the total luminous flux of the LED is improved, and the heat dissipation is facilitated. The LED light is collimated by TIR, and then the tilt angle of different TIR surfaces is passed, so that most of the light converges toward the focus of the condenser lens, and then passes through the condenser lens 603 to be refracted and concentrated, and light above the cut-off line is shielded by the light shielding plate 604 to form a low-beam light spot. Unfortunately, the virtual focus of the TIR lens of the TIR lens LED low beam system converged on the condenser lens 603 is large, and the light at the far side of the ground cannot be concentrated, which causes waste of the near-field light on the ground.

[0012] As shown in Figs. 6A and 6B, the high beam lamp ECE R122 regulations specify the brightness requirements on the horizontal line of the test point, but do not specify the upper limit of the brightness of the local area anti-dazzle area on the horizontal line, which may cause the opposite vehicle driver and the road pedestrian to dazzle causing Traffic accident. In order to solve the problem of dazzle of high beam, matrix high beam is currently used in the market, wherein a sensor is used to collect the position information of the vehicle and pedestrian in front of the vehicle, so that the single-point LED at the corresponding position is turned off, so that the corresponding vehicle and pedestrian position form a dark area, so as to prevent dazzle. Nevertheless, the matrix high beam is costly and powerful. It is difficult to popularize the matrix high beam to the middle and low-end vehicles. On the other hand, the instantaneous change of the spot in front and the light below the level will also affect the driver's judgment of the road ahead.

[0013] As shown in FIG. 7A, after the solar parallel light is refracted by the prism, the white light is refracted into red, orange, yellow, green, cyan, blue, and purple, wherein the offset angle of blue light is larger than the offset angle of yellow light, that indicates that, corresponds to the same medium, the shorter the wavelength the larger the refractive index is. The refractive index is defined based on the wavelength of sodium yellow light. The refractive indexes of light of different wavelengths are different for the same medium, wherein the longer the wavelength, the smaller the refractive index will be, while the shorter the wavelength, the larger the refractive index will be. Currently, for white LEDs, it usually utilizes blue light + phosphor to be excited to generate white light, which is mainly a mixture of blue light and yellow light. For example, the refractive index of PC material is 1.586, wherein the refractive index is 1.594 when the blue light wavelength is 470um. Therefore, the projection optical system must have blue light runoff.

[0014] In order to reduce the blue light runoff, various methods are adopted, such as dotting on the input optical surface of the condenser lens, moving the condenser lens to focus it, so as to reduce the light distribution with a large incident angle. As shown in FIG. 7B, the current mainstream headlamp optical structure on the market adopts a projection optical system, wherein the LED light source is placed at the focus F1 of the ellipsoidal surface structure8001, wherein the light is reflected by the ellipsoidal surfaces 8001 and then converged on F2, wherein a condenser lens 8003 is placed in front F2, so that the light passed through F2 re-converges to make the central area meet the light intensity required by laws and regulations, wherein a cut-off line baffle is placed at F2, so as to form a dark zone with a cut-off line shape above the projected light spot, so as to meet the requirements of the test points specified by laws and regulations. However, the angle of incidence α1 of the light reflected by the reflective surfaces far from the LED to the condenser lens 8003 is large, so that the offset angle of the blue light is large, so that the proportion of blue light in the central region is large, so that there will be a serious blue light runoff at the cut-off line. Furthermore, the blue area is large, wherein the color is seriously beyond the area stipulated by laws and regulations. In order to reduce the blue light runoff, the condenser lens 8003 is slightly moved outwardly. The incident angle of the incident light to the condenser lens 8003' is also α1, but the distance of the incident point from the condenser lens 8003' is farther, so that the light nudges down. The proportion of blue light in the central area is reduced, so as to reduce the blue light runoff at the center, but the light above the condenser lens will shifts to the dark area, causing the cut-off line of the light and dark to become unclear. In another method, by modifying the ellipsoidal reflection, the light of the reflective surfaces of the region with a large incident angle α1 can be corrected and shifted upward, so that the angle α1 becomes smaller, so as to reduce the central blue light runoff. Meanwhile, the light passing through the focus of the condenser lens 8003 is also reduced, so that the light intensity in the central area decreases.

[0188] The present invention mainly provides a lighting system integrating high and low beams, which comprises a low beam system 10 and a high beam system 20, wherein the low beam system 10 comprises a first linear focus reflector 12, while the high beam system comprises a second linear focus reflector 22, wherein the low beam system 10 forms linear focus by the light converging effect of the first linear focus reflector 12, so as for providing a low beam light spot, wherein the high beam system 20 forms linear focus by the light converging effect of the second linear focus reflector 22, so as for providing a high beam light spot.

[0189] Referring to Figs. 8-14, according to the above first embodiment of the present invention, the lighting system integrating high and low beams can be utilized for the illumination of a conveyance. The conveyance can be a road surface conveyance, such as a vehicle and etc., a water conveyance, such as a boat, a ship, and etc. or an air conveyance. The low beam system 10 comprises at least a first linear light source 11, at least a first linear focus reflector 12, at least a first condenser lens 13, and at least a cut-off screen 14. The first linear focus reflector 12 is utilized for conducting reflection for the first linear light source 11. The first linear light source 11 is perpendicular to the optic axis of the low beam system and is horizontally and linearly aligned as well as coincides with the linear focus F1 of the first linear focus reflector 12. At least part of the light emitted by the first linear light source 11 is reflected by the first linear focus reflector 12 to be converged on a linear focus F2. The first condenser lens 13 is mounted, arranged, and provided in front of the linear focus F2, so as to utilize lens principles to converge the light passing the linear focus F2 into a horizontal linear high density light spot. The cut-off screen 14 is mounted, arranged, and provided at the position of the linear focus F2, so as to shade and block the light above the cut-off line and to eventually allow the low beam system 10 to form a low beam lamp light spot.

[0190] Referring to Figs. 8-22, the high beam system 20 comprises at least a second linear light source 21, at least a second linear focus reflector 22, at least a second condenser lens 23, and at least an anti-glare board 24. The second linear focus reflector 22 is connected with the second linear light source 21 for conducting reflection for the second linear light source 21. The second linear light source 21 is perpendicular to the optic axis of the high beam system and is horizontally and linearly aligned as well as coincides join the linear focus F1 of the second linear focus reflector 22. At least part of the light emitted by the second linear light source 21 is reflected by the second linear focus reflector 22 to be converged on a linear focus F2. The second condenser lens 23 is mounted, arranged, and provided in front of the linear focus F2, so as to utilize lens principles to converge the light passing the linear focus F2 into a horizontal linear high density light spot. The anti-glare board 24 is mounted, arranged, and provided at the position of the linear focus F2, so as to form and create an anti-glare zone, which can be referred to the zone I in Fig. 7B.

[0191] Specifically, according to the above first embodiment of the present invention, the first linear light source 11 is embodied as a plurality of LEDs 111 horizontally aligned. According to an implementation, the LEDs 111 can be five-chip LED module of 1500Lm and 5700K color temperature arranged in the middle and two single-chip ceramic packaged LED of 250Lm, warm white light, and 3000K color temperature respectively in the left and right, which hybridly utilizes white light and warm white light to lower the color temperature of the complete lamp, which enhances the penetrability of the light under foggy day and rainy day and make the state of roads more clear. All the LEDs 111 are arranged in a horizontal linear manner and the illumination direction of the LEDs 111 is the same to the direction of the optic axis of the first linear light source 11 and coincides with the focus of the first linear focus reflector 12.

[0192] According to another alternative mode of the above first embodiment of the present invention, the first linear light source 11 can be a set of horizontally and linearly aligned multicore LED module, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the first linear light source.

[0193] According to another alternative mode of the above first embodiment of the present invention, the first linear light source 11 is a plurality sets of horizontally and linearly aligned single-chip LED modules or a LED light source formed by a set of horizontally and linearly aligned single-chip LED module and a set of horizontally and linearly aligned single-chip LED module of a top left or top right half, which is suitable for the low beam lamp optical system.

[0194] According to another alternative mode of the above first embodiment of the present invention, the first linear light source 11 is a plurality sets of horizontally and linearly aligned multicore LED modules, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the second linear light source.

[0195] In other words, because the focuses F1 and F2 of the first linear focus reflector 12 and the second linear focus reflector 22 of the present invention are linear, the LEDs 111 can be linearly arranged and aligned and the quantity thereof will not be limited, which allows the lamp to provide a higher optical density and total luminous flux, so as to reduce the electric current of single LED 111. Hence, the luminous efficiency of the LED 111 can be higher.

[0196] According to the above first embodiment of the present invention, the first linear focus reflector 12 comprises a first main reflection structure 121 and a first subsidiary reflection structure 122, wherein the first main reflection structure 121 comprises two first main reflecting boards 1211 arranged opposite to each other, wherein the first subsidiary reflection structure 122 comprises two first subsidiary reflecting boards, which basically have the same structure and are arranged opposite to each other on the sides, wherein the first subsidiary reflecting boards 1221 are respectively arranged on the sides of the two first main reflecting boards 1211, such that the two first subsidiary reflecting boards 1221 and the two first main reflecting boards 1211 can jointly form a reflecting cavity, which has a first opening 120 to allow the light emitted by the first linear light source 11 to go out through the first opening 120. The first linear light source 11 is arranged to horizontally and linearly extend toward the first opening 120, so as to allow the light directly projected from the first linear light source 11 out of the first opening 120 without being reflected by the first linear focus reflector 12 to directly reach the first condenser lens 13 and to be refracted to the road surface. The first condenser lens 13 can be arranged at the position in front of the linear focus F2 for condensation.

[0197] It is understandable that the first linear focus reflector 12 may also be other reflection structure capable of forming the linear focus F1 and F2 according to another alternative modes. Namely, it shall not be limited by the above four structures of the reflecting board, but may include structures of the reflecting board of other quantities or shapes.

[0198] In addition, each of the first subsidiary reflecting boards 1221 comprises a first main portion 12211 and a first extension portion 12212, wherein the first opening 120 is formed and defined between the first main portion 12211 and the first main reflecting board 1211. The inner side of the first main portion 12211 is curvy, so as for reflecting the light emitted by the first linear light source 11. The first extension portion 12212 is extended outward from the first main portion 12211 and then bent inward. When the first extension portion 12212 is extended outward, it forms and defines a first included angle α1 with the first main portion 12211. The range of the first included angle α1 can be 90°-270°. The first extension portion 12212 bent inward form and define a second included angle α2. The range of the second included angle α2 can be 0°-180°.

[0199] It is worth noticing that each first main reflecting board 1211 comprises a first middle horizontal linear reflecting surface 12111 and a first light spreading cambered surface 12112 arranged on the inner side thereof. The first middle horizontal linear reflecting surface 12111 is formed by extending the inner surface of the first main reflecting board 1211 from an end thereof that is closer to the first linear light source 11 to the other end of the first opening 120. The first middle horizontal linear reflecting surface 12111 is a surface formed by stretching the combination mainly of the basis of ellipse lines and partially of the basis of non-ellipse lines. The first light spreading cambered surface 12112 is extended outward from the first middle horizontal linear reflecting surface 12111 and is arranged and disposed at the rear end of the first main reflecting board 1211. The first main portion 12211 of the first subsidiary reflecting board 1221 comprises a first ellipse line reflecting surface 122111 and a first non-ellipse line reflecting surface 122112. The first ellipse line reflecting surface 122111 is extended from an end of the internal of first main portion 12211 close to the first linear light source 11 to the other end of the first opening 120. The first non-ellipse line reflecting surface 122112 is extended outward from the first ellipse line reflecting surface 122111 and is arranged and disposed at the rear end of the internal of the first main portion 12211. The first extension portion 12212 is extended inward relatively to the first main portion 12211. The inner side of the first extension portion 12212 is a first collecting surface 122121 and the first collecting surface 122121 is provided on the inner side of the first extension portion 12212. Therefore, the first collecting surface 122121 is also inclined inward to form the second included angle α2.

[0200] It is understandable that the first linear focus reflector is in a light funnel shape according to the present embodiment of the present invention, but it may also have other appearances, such as sphere and etc., according to some alternative mode, as long as it can provide a reflecting surface structure to form and define the linear focus F1 and the linear focus F2 internally.

[0201] In addition, the perpendicular cut-off surface of the first horizontal linear reflecting surface 12111 is formed by ellipse lines, ellipse lines and part of non-ellipse lines, or a reflecting surface of non-ellipse lines, to reflect the light to the linear focus F2, or a horizontal linear reflecting surface having pellets thereon.

[0202] The first horizontal linear reflecting surface 12111 can be linear or linear with slight curve (e.g. within 5 radian) so as for increasing the light distribution vertically.

[0203] In addition, the reflection surfaces on the two sides of the low beam system are respectively a stretching surface based on ellipse lines with part of non-ellipse lines or further with slight curve (e.g. within 5 radian), so as for increasing the light distribution vertically. For instance, according to the present embodiments, the reflecting surfaces of the two sides of the low beam system respectively have at least an ellipse line reflecting surface 122111 adjacent to the first linear light source and at least a non-ellipse line reflecting surface 122112 extended from the ellipse line reflecting surface. The surface shape of each of the first collecting surfaces 122121 is vertical plane, inclined plane, cambered surface, or strip cambered surface.

[0204] Referring to Fig. 11, according to the above first embodiment of the present invention, the cut-off screen 14 comprises a base plate 141 and a shading baffle 142 connected with each other, wherein the cut-off screen 141 is mounted at the position of the second included angle α2 and arranged along the linear focus F2. In other words, the light emitted by the first linear light source 11 will be reflected and converged by the first linear focus reflector 12 onto the position of the linear focus F2 at the second included angle α2. Then the light above the base plate 141 will be shade and block by the cut-off screen 14 with the shading baffle 142. Namely, the light corresponding to the dark zone according to the light distribution standards will be shaded, so as to avoid glare and dazzle from occurring and to allow the light to be projected to the road surface and road sign. According to another embodiment, the cut-off screen 14 may be provided without the base plate 141, but be integrally formed with the first linear focus reflector 12. Alternatively, the cut-off screen 14 may be provided without the base plate 141, but be directly mounted on the first linear focus reflector 12.

[0205] Similarly, according to the above first embodiment of the present invention, the second linear light source 21 is embodied as a plurality of LEDs 211 horizontally aligned. The LEDs 211 can be five-chip LED module of 1500Lm and 5700K color temperature arranged in the middle and two single-chip ceramic packaged LED of 250Lm warm white light, and 3000K color temperature respectively in the left and right, which hybridly utilizes white light and warm white light to lower the color temperature of the complete lamp, which enhances the penetrability of the light under foggy day and rainy day and make the state of roads more clear. All the LEDs 211 are arranged in a horizontal linear manner and the illumination direction of the LEDs 211 is the same to the direction of the optic axis of the second linear light source 21 and coincides with the focus F1 of the second linear focus reflector 22.

[0206] According to another alternative mode of the above first embodiment of the present invention, the second linear light source 21 is a set of horizontally and linearly aligned multicore LED module, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the second linear light source.

[0207] According to another alternative mode of the above first embodiment of the present invention, the second linear light source 21 is a plurality sets of horizontally and linearly aligned single-chip LED modules.

[0208] According to another alternative mode of the above first embodiment of the present invention, the second linear light source 21 is a plurality sets of horizontally and linearly aligned multicore LED modules, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the second linear light source.

[0209] The second linear focus reflector 22 comprises a second main reflection structure 221 and a second subsidiary reflection structure 222, wherein the second main reflection structure 221 comprises two second main reflecting boards 2211 arranged opposite to each other, wherein the second subsidiary reflection structure 222 comprises two second subsidiary reflecting boards 2221 arranged opposite to each other, which are respectively arranged on the sides of the two second main reflecting boards 2211. The two second subsidiary reflecting boards 2221 and the two second main reflecting boards 2211 form and define a second opening 220, so as to allow the light emitted by the second linear light source 22 to pass through the second opening 220 to go out. The second linear light source 21 is arranged to horizontally and linearly extend toward the second opening 220, so as to allow the light directly projected from the second linear light source 21 out of the second opening 220 without being reflected by the second linear focus reflector 22 to directly reach the second condenser lens 23 and to be refracted to the road surface. The second condenser lens 23 can be arranged at the position in front of the linear focus F2 for condensation.

[0210] Correspondingly, it is understandable that the second linear focus reflector 22 may also be other reflection structure capable of forming the linear focus F1 and F2 according to other alternative modes. Namely, it shall not be limited by the above four structures of the reflecting board, but may include structures of the reflecting board of other quantities or shapes.

[0211] It is worth noticing that each second main reflecting board 2211 can have a curvy sunken portion 22110 arranged thereon right in the middle of the second main reflecting board so as for reflecting the light emitted by the second linear light source 21.

[0212] Each of the second subsidiary reflecting boards 2221 comprises a second main portion 22211 and a second extension portion 22212, wherein the second opening 220 is formed and defined between the second main portion 22211 and the second main reflecting board 2211. The inner side of the second main portion 22211 is a linear reflection surface 222111, so as for reflecting the light emitted by the second linear light source 21. The second extension portion 22212 is extended outward from the second main portion 22211 and bent inward, wherein there is a third included angle β3 formed and defined between the outward extended second extension portion 22212 and the second main portion 22211, wherein the range of the third included angle β3 is 90°-270°.

[0213] It is worth noticing that each of the second main reflecting boards 2211 comprises a second middle partial rotating reflecting surface 22113, a second horizontal linear reflecting surface 22111, and a second light spreading cambered surface 22112 arranged on the inner side thereof. The second main portion 22211 has a second mirror surface 222111 arranged on the inner side thereof. The second extension portion 22212 has a second collecting surface 222121 arranged on the inner side thereof. The second middle partial rotating reflecting surface 22113 is formed by the above mentioned curvy sunken portion 22110 and disposed in the middle of the second main reflecting board 2211, so as to reflect the light emitted by the second linear light source 21 to the central area of the second linear focus F2. The second light spreading cambered surface 22112 is mainly to shift part of the light of the second linear light source 21 upward from the second linear focus F2, so as to enhance the light distribution of the ground illumination. The second mirror surface 222111 utilizes a plane as the basis to mirror and reflect the light of the second linear light source 21 to the second horizontal linear reflecting surface 22111 or the opposite mirror surface, so as to have the light eventually be reflected to the second linear focus F2. In other words, a virtual focus F1' is formed and defined by means of the second mirror surface 222111. The virtual focus F1' is disposed at the focus of the second horizontal linear reflecting surface 22111, such that the light been reflected will be converged again on the linear focus F2. The second collecting surface 222121 is mainly formed by a plane and is inclined outward for a predetermined angle, so as to reflect the light beyond the subtended angle of the second condenser lens to the condenser lens 23 to be refracted to a ground zone with a big angle to the left and right.

[0214] It is understandable that the second linear focus reflector 20 is in a light funnel shape according to the present embodiment of the present invention, but it may also have other appearances, such as sphere and etc., according to some alternative mode, as long as it can provide a reflecting surface structure to form and define the linear focus F1 and the linear focus F2 internally.

[0215] Person skilled in the art should be able to understand that the perpendicular cut-off surface of each of the second horizontal linear reflecting surfaces 22111 and the middle partial rotating reflecting surfaces 22113 is formed by ellipse lines, ellipse lines and part of non-ellipse lines, or a reflecting surface of non-ellipse lines to reflect the light to the linear focus F2, or to dispose and arrange pellets on the middle partial rotating reflecting surfaces and the second horizontal linear reflecting surfaces.

[0216] Besides, the second horizontal linear reflecting surface 22111 can be linear or linear with slight curve, so as for increasing the light distribution vertically.

[0217] It is understandable that the mirror surfaces 222111 on the two sides are planes or planes with slight curve, so as for increasing the light distribution vertically. The surface shape of each of the second collecting surfaces 222121 may be vertical plane, inclined plane, cambered surface, or strip cambered surface.

[0218] Because the opening of the second linear focus reflector 22 is relatively small, which, according to the present embodiment, is 15 degree opening for the left and right respectively and 11 degree opening for the up and down respectively, hence the light projected by the second linear light source 21 may directly hit the second condenser lens 23 to be refracted to the ground. Therefore, it can achieve the function of collecting all the light of the second linear light source in 360° three-dimensionally. As a result, the light collection rate of the second linear focus reflector 22 is high, which is able to not only enhance the brightness of the lamp, but also reduce the power consumption of the entire lamp.

[0219] Moreover, the second linear focus reflector 22 further comprises an anti-glare board 24 provided, arranged, and disposed at the position of the second linear focus F2. Referring to Figure, the anti-glare board 24 comprises a base 241 and an anti-glare baffle 242. The anti-glare baffle 242 comprises an opening 2420 arranged thereon for the light of the second linear light source 21 to pass through to form the high beam light spot. The opening 2420 may, based on actual needs or customer requests, be arranged into the shape of triangle, rectangle, circle, or any other shape. As long as it achieves the same or similar effect or result to the present invention, it shall be in the scope of the present invention. Namely, the implementation or practice of the present invention shall not be limited thereby. The anti-glare zone I must have a predetermined brightness, but it must also have a limit, so as to prevent glare without affecting the observation of the state of roads. Besides, the upper 3° Line 1 in the middle has a minimum and maximum brightness requirement, so as to ensure there is sufficient brightness for seeing the street sign above clearly, but not to render glare and dazzle to the pedestrians and drivers of the opposite side when the vehicle is turning.

[0220] The anti-glare board 24 is made of a transparent, opaque semi-transparent material or a dichroic glass. The opaque anti-glare board is utilized to shade and block the light of the glare zone. The transparent and semi-transparent anti-glare board 24 has part of the area thereof be coarsened or granulated, so as to weakened the light of the glare zone. The dichroic glass without electrifying has disorder molecular arrangement in the liquid crystal membrane thereof obstructing the light so as to allow the dichroic glass to weaken the light. Dichroic glass with electrifying has ordered molecular arrangement in the liquid crystal membrane thereof allowing more light to pass through the dichroic glass.

[0221] It should be noted that, according to the above first embodiment of the present invention, because the opening of the first linear focus reflector 12 is relatively small and the reflecting surfaces in the inside are deep, in order for coating and plating the reflection layer on the reflecting surfaces, the first linear focus reflector 12 can be arranged to include a first upper linear focus reflector 12a and a first lower linear focus reflector 12b, which are respectively mounted on the top and bottom sides of the first linear light source 11, so as to reflect for the first linear light source 11. The structure of the first upper linear focus reflector 12a and the first lower linear focus reflector 12b are basically the same, which respectively have part of the above mentioned first linear reflection surface 12111, the first light spreading cambered surface 12112, the first ellipse line reflecting surface 122111, the first non-ellipse line reflecting surface 12211, and the first collecting surface 122121. Hence, they may substitute be exchanged for each other, so as to reduce the part types of the product and therefore reduce the costs of the product.

[0222] Similarly, the first linear focus reflector 12 may also be longitudinally divided into two symmetrical portions that are replaceable to each other, which is helpful for coating reflecting layer on the reflecting surface in the first linear focus reflector 12. Besides, it can also reduce the part types of the product and therefore enhance productivity. Besides, the material of the reflection layer of the reflecting surface of the first linear focus reflector 12 can be selected, based on different usage requirements, from the materials such as metal coating, alloy coating, compound coating, and etc.. Also, the first linear focus reflector can be provided as an integral structure or other joint structure. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0223] Similarly, because the opening of the second linear focus reflector 22 is relatively small and the reflecting surfaces in the inside are deep, in order for coating and plating the reflection layer on the reflecting surfaces, the second linear focus reflector 22 can be arranged to include a second upper linear focus reflector 22a and a second lower linear focus reflector 22b, which are respectively mounted on the top and bottom sides of the second linear light source 21 so as to reflect for the second linear light source 21. The structure of the second upper linear focus reflector 22a and the second lower linear focus reflector 22b are basically the same, which respectively have part of the second middle partial rotating reflecting surface 22113, the second horizontal linear reflecting surface 22111, the second light spreading cambered surface 22112, the second mirror surface 222111, and the second collecting surface 222121, so as can substitute and be exchanged for each other, which can reduce the part types of the product and therefore reduce the costs of the product.

[0224] Similarly, the second linear focus reflector 22 may also be longitudinally divided into two symmetrical portions that are replaceable to each other, which is helpful for coating reflecting layer on the reflecting surface in the second linear focus reflector 22.

All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0225] The lighting system integrating high and low beams of the present invention is mainly utilized in conveyances, such as vehicles. The low beam system 10 can achieve sufficient light intensity to illuminate the front road surface. The high beam system 20 can achieve sufficient light intensity to illuminate the front road surface without producing glare. Hence, the utilization of the lighting system integrating high and low beams of the present invention is not only high efficient and safe. At least part of the light of the first linear light source 11 and the second linear light source 21 are respectively reflected by the first linear focus reflector 12 and the second linear focus reflector 22 to be converged on the linear focus F2. The linear concentrated zone of the light of the horizontal axis of the linear focus F2 can reach 4mm high and 25mm wide and the light is even and uniform in the area along the horizontal direction. When the widths of the first linear focus reflector 12 and the second linear focus reflector 22 are increased, the width of the concentrated zone of the light will be expanded correspondingly.

[0226] Moreover, according to the above first embodiment of the present invention, the low beam system 10 and the high beam system 20 of the lighting system integrating high and low beams are two independent optical systems. The high beam system 20 not only satisfies the high beam rules and standards, but also has the same ground area illumination to it of the low beam system 10. Hence, when it needs to utilize the high beam system 20 for illumination, it has to switch the low beam system 10 into the high beam system. That is to say, the low beam system 10 can then be closed. Therefore, the lighting system integrating high and low beams of the present invention can greatly reduce the consumption of the entire lamp. Meanwhile, because the lighting system integrating high and low beams of the present invention is capable of providing high density light, thus when the low beam system 10 is switch into the high beam system 20, it does not have to utilize a conventional mechanical structure that moves the screen away through a solenoid valve, such that, without the power consumption of the solenoid valve, it can reduce the consumption of the entire lamp to a certain extent.

[0227] Besides, for the high beam system, because the second linear focus reflector 22 has higher optical density, smaller size, an anti-glare system that is favor of liquid crystal lattice, and smaller liquid crystal display panel, the anti-glare board of the high beam system is a high density lattice liquid crystal display panel, and both the positions of the lattice of the liquid crystal display panel and the bright/dark lattice arrangement and appearance above the horizontal line can be controlled through circuits, it can achieve an anti-glare result.

[0228] Referring to Figs. 15-16, the lighting system integrating high and low beams further comprises an outer cover 30, an outer lens 50, and a heat dissipation body 40, wherein the outer cover 30 is for covering the high beam system 20 and the low beam system 10, so as to protect the high beam system 20 and the low beam system 10 and extend their service lives. Moreover, the outer cover 30 can also shade and keep the scattered light emitted by the high beam system 20 and the low beam system 10 in the internal thereof, so as to enhance the illuminating effect of the lighting system integrating high and low beams. The outer lens 50 is affixedly connected with the front end of the outer cover and is able to further distribute the light of the low beam system 10 and the high beam system 20.

[0229] Referring to Fig. 16, the outer cover 30 comprises a first portion 31 and a second portion 32. The first portion 31 and the second portion 32 are connected to form an accommodation cavity 300 for accommodating the low beam system 10 and the high beam system 20. The second portion 32 acts as the back section. The metal heat dissipation body 40 is disposed inside of the second portion 32. The first portion 31 acts as the front section and comprises a first opening 311 and a second opening 312. The first opening 311 is for placing the first condenser lens 13 and for the light of the first linear light source 11 to pass through. The second opening 312 is for placing the second condenser lens 23 and for the light of the second linear light source 21 to pass through.

[0230] Preferably, the outer lens 450 is affixedly connected with the front end of the outer cover 30 and connected with the low beam system 10 and the high beam system 20 through sealant, such that the low beam system 10 and the high beam system 20 can be waterproof and dustproof. The first linear light source 11 of the low beam system 10 and the second linear light source 21 of the high beam system 20 can both be directly affixed on the heat dissipation body 40 that is made of metal. The heat dissipation body 40 may be, for example, heat dissipation board, radiating pipe, heat dissipation rod, and etc.. Because the heat transmission speed of the metal heat dissipation body 40 is fast, the arrangement of the metal heat dissipation body 40 can avoid service life decrease of the first linear light source 11 and the second linear light source 21 due to rapid temperature increase or failure of timely heat dissipation.

[0231] Preferably, the lighting system integrating high and low beams of the present invention further comprises a metal heat dissipation board 60, wherein the first linear light source 11 and the second linear light source 21 are directly affixed on the metal heat dissipation board 60 by means of, for example, welding, soldering, screwing, and etc.. Preferably, the heat conduction surfaces of the LEDs of the first linear light source 11 and the second linear light source 21 are directly mounted on the metal heat dissipation board 60 of a large size. Because the surface area of the metal heat dissipation board 60 is big, it will be favor of heat dissipation. The first linear light source 11 and the second linear light source 21 that are affixed on the metal heat dissipation board 60 will be affixedly connected with the metal heat dissipation body 60. Because the contacted area of the metal heat dissipation board 60 and the metal heat dissipation body 40 is big, it can therefore further enhance the heat dissipation of the first linear light source 11 and the second linear light source 21, so as to extend the service lives of the first linear light source 11 and the second linear light source 21.

[0232] Fig. 17 is an exploded view of a lighting system integrating high and low beams according to an alternative mode of the present invention. According to the embodiment, the lighting system integrating high and low beams comprises a high beam system 20' and a low beam system 10'. The high beam system 20' and the low beam system 10' can respectively provide a high beam light spot and a low beam light spot. The differences from the previous embodiment include that, according to the present embodiment, the low beam system 10' and the high beam system 20' utilize linear focus reflectors of mostly the same structure. In other words, according to the present embodiment, the structures of the second linear focus reflector of the high beam system 20' and the first linear focus reflector 12' of the low beam system 10' are basically the same. Namely, the low beam and high beam system 10' and 20' respectively have a main reflection structure 121' and a subsidiary reflection structure 122'. The main reflection structure 121' comprises two main reflecting boards 1211' opposite arranged. The subsidiary reflection structure 122' comprises two subsidiary reflecting boards 1221' opposite arranged and disposed on the sides respectively. The reflecting board 1221' respectively has the two main reflecting board 1211' arranged on the sides. The two subsidiary reflecting boards 1221' and the two main reflecting boards 1211' form and define a reflecting cavity having an opening. Each of the linear focus reflectors comprises two partial linear focus reflector 12a' and 12b' that are structurally symmetry and each of the them has the reflecting surface structures similar to the first linear reflection surface 12111, the first light spreading cambered surface 12112, the first ellipse line reflecting surface 122111, the first non-ellipse line reflecting surface 12211, and the first collecting surface 122121 of the above mentioned embodiment. Therefore, it can reduce the total quantity of the parts of the lighting system integrating high and low beams, so as to enhance the productivity of the lighting system integrating high and low beams.

[0233] Fig. 18 is an exploded view of a lighting system integrating high and low beams according to another alternative mode of the present invention. According to the embodiment, the lighting system integrating high and low beams comprises a low beam system 10" and a high beam system 20". The low beam system 10" and the high beam system 20" can respectively provide a low beam light spot and a high beam light spot. The differences to the above-mentioned embodiment include that, according to the present embodiment, the first linear focus reflector of the low beam system 10" utilizes basically the same structure to the second linear focus reflector 22" of the high beam system 20". Namely, the linear focus reflector 22" of the low beam system 10" comprises a main reflection structure 221" and a subsidiary reflection structure 222", wherein the main reflection structure 221" comprises two main reflecting boards 2211" arranged opposite to each other, wherein the subsidiary reflection structure 222" comprises two subsidiary reflecting boards 2221" arranged opposite to each other, which are respectively arranged on the sides of the two main reflecting boards 2211". The two subsidiary reflecting boards 2221" and the two second main reflecting boards 2211" form and define an opening, so as to allow the light emitted by the linear light source 11 to pass through the opening to go out. Also, each the linear focus reflector comprises two linear focus reflector portions 22a' and 22b' that are structurally symmetry and respectively have reflecting surface structures similar to the second middle partial rotating reflecting surface 22113, the second horizontal linear reflecting surface 22111, the second light spreading cambered surface 22112, the second mirror surface 222111, and the second collecting surface 222121, as mentioned in the above embodiment, formed thereon.

[0234] Fig. 19A is a sectional view of a lighting system integrating high and low beams according to another alternative mode of the present invention. The lighting system integrating high and low beams comprises an optical system 10"', a metal heat dissipation board 60"', a metal heat dissipation body 40"', an outer cover 30"', and an outer lens 50"'. The optical system 10"' comprises a linear light source 11'", a linear reflector 12"', a condenser lens 13"', and a cut-off screen 14"'. The linear light source 11"' and the metal heat dissipation board 60"' are contacted and connected with each other. The metal heat dissipation body 40"' is mounted and arranged on an end of the outer cover 30'" internally and is connected with the metal heat dissipation board 60"', so as for conducting heat dissipation for the linear light source 11'". The linear reflector 12"' is utilized to reflect the light emitted by the linear light source 11"' to the condenser lens 13"'. Then the light can be refracted by the condenser lens 13"' . The optical system 10"' is covered in the outer cover 30"'. The outer lens 50"' is mounted on the other end of the outer cover 30"' in order to further refract the light emitted by the linear light source 11"'. The cut-off screen 14"' is mounted and arranged between the linear reflector 12"' and the condenser lens 13"' for shading the light above the base plate of the cut-off screen 14"', so as to allow the lighting system integrating high and low beams to form a low beam light spot.

[0235] According to the present embodiment, the linear reflector 12"' comprises an upper linear focus reflector 12a"' and a lower linear focus reflector 12b"'. By utilizing and arranging linear reflectors 12"' of the same structure, it not only facilitates the coating and plating of the reflecting coating on the reflecting layers of the internal of the linear reflectors 12"', but also benefits in reducing the part types of the linear reflectors 12"', which helps to enhance the production efficiency of the linear reflector 10"'. Nevertheless, the specific implementations and practices of the present invention shall not be limited here. All changes that are based on the present invention and achieve the same or similar effect to the present invention shall be in the scope of the present invention.

[0236] It is worth noticing that the low beam cut-off line may be made through changing the shape and material of the cut-off screen 14'" according to the present embodiment. Also, the cut-off screen 14"' is moveably mounted in the lighting system integrating high and low beams. When an external force is exerted, such as to control the solenoid valve to move the cut-off screen 14"', the lighting system integrating high and low beams can provide low beam light spot or high beam light spot based on the needs. Namely, when the cut-off screen 14"' is shifted away, the lighting system integrating high and low beams can provide a high beam light spot, while when the cut-off screen 14'" is shifted back, the lighting system integrating high and low beams can provide a low beam light spot. In other words, the lighting system integrating high and low beams of the embodiment is capable of providing both low beam light spot and high beam light spot with one system.

[0237] In addition, as an alternative mode of the present embodiment, the anti-glare board may also be driven to move, such that when the cut-off screen 14"' is shifted away, the anti-glare board can be put into the light path, so as to provide a high beam light spot.

[0238] Fig. 20 is a sectional view of a lighting system integrating high and low beams according to another alternative mode of the present invention. The lighting system integrating high and low beams comprises an optical system 10"", a metal heat dissipation board 60"", a metal heat dissipation body 40"", a heat dissipation reinforcement member 90"", an outer cover 30"", and an outer lens 50"". The optical system 10"" comprises a linear light source 11"", a semi-linear focus reflector 12"", a condenser lens 13"", and a cut-off screen 14"". The linear light source 1 1"" and the heat dissipation reinforcement member 90"" are contacted and connected with each other. The metal heat dissipation board 60"" is closely attached on the heat dissipation reinforcement member 90"", so as for conducting heat dissipation for the linear light source 11"". The semi-linear focus reflector 12"" is utilized to reflect the light emitted by the linear light source 11"" to the condenser lens 13"". Then the light can be refracted by the condenser lens 13"". The optical system 10"" is arranged in the outer cover 30"". The outer lens 50"" is mounted on the other end of the outer cover 30"" in order to further refract the light emitted by the linear light source 11"". The cut-off screen 14"" is mounted and arranged between the linear reflector 12"" and the condenser lens 13"" for shading the light above the base plate of the cut-off screen 14"", so as to allow the lighting system integrating high and low beams to form a low beam light spot.

[0239] The linear light source 11"" is arranged to face the direction of the inner surface of the semi-linear focus reflector 12"" and the side thereof will face the opening of the semi-linear focus reflector 12"". Namely, the outlet of the light of the linear light source 11"" will be perpendicular to the optic axis of the entire optical system, rather than along the direction of the optic axis and having the luminous side facing the opening as embodied in the previous embodiment. The mounting direction of the linear light source 11"" may also be perpendicular to or inclined to the optic axis with a predetermined angle, wherein the present invention shall not be limited here.

[0240] The differences of the present embodiment to it of the Fig. 2 include that the linear light source 10"" may comprise a plurality sets of LED modules, which light can be reflected by the semi-linear focus reflector 12"" to be converged on the linear focus F2, so as to increase the total luminous flux of the lighting system integrating high and low beams. Besides, the heat dissipation reinforcement member 90"" of the present embodiment is a metal heat dissipation piece with large surface area, so as to dissipate the heat produced by the operation of the linear light source 10"" rapidly. Also, the lighting system integrating high and low beams of the present invention utilizes the cut-off screen 14"" for providing low beam light spot.

[0241] It is worth noticing that the low beam cut-off line may also be made through changing the shape and material of the cut-off screen 14"' according to the present embodiment. Meanwhile, the cut-off screen 14"' can be movably mounted in the lighting system integrating high and low beams, such that when the cut-off screen 14"' is moved, it can allow the lighting system integrating high and low beams to form and provide a high beam light spot. In other words, the lighting system integrating high and low beams of the embodiment is capable of providing both low beam light spot and high beam light spot with one system.

[0242] Hence, the lighting system integrating high and low beams of the present invention can be utilized and applied flexibly based on customer requests or actual needs. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0243] Referring to Figs. 23-26, the present invention provides a headlamp, which can be a low beam headlamp or a high beam headlamp. The headlamp comprises at least a linear light source 11, at least a reflective device 70, and at least a condenser lens 13. When it also comprises at least a cut-off screen 14, it will be embodied as a low beam headlamp. When it does not utilized to shade and block the light for forming a light and shade cut-off line, the headlamp can be embodied as a high beam headlamp. However, the high beam headlamp may also have the above mentioned anti-glare board. Here, for an example of low beam headlamp, the reflective device 70, at the linear focus F1, reflects at least part of the light emitted by the linear light source 11. At least part of the light of the linear light source 11 reflected by the reflective device 70 is converged on a linear focus F2. The cut-off screen 14 is mounted and arranged at the linear focus F2 for shading the light above the cut-off line. The first condenser lens 13 is mounted and arranged in front of the linear focus F2 to refract the light of the linear light source 11 through principle of lens, so as to eventually form a low beam lamp light spot for the low beam headlamp

[0244] Specifically speaking, the linear light source 11 is embodied as a plurality of LEDs 111. The LEDs 111 can be five-chip LED module of 1500Lm and 5700K color temperature arranged in the middle and two single-chip ceramic packaged LEDs 111 of 250Lm, warm white light, and 3000K color temperature respectively arranged in both the left and right, which hybridly utilizes white light and warm white light to lower the color temperature of the complete lamp, which enhances the penetrability of the light under foggy day and rainy day and makes the state of roads more clear. All the LEDs 111 are arranged in a horizontal linear manner and the illumination direction of the LEDs 111 is the same to the direction of the optic axis of the low beam headlamp and coincides with the focus F1 of the reflective device.

[0245] According to another alternative mode of the embodiment of the present invention, the linear light source 11 is a set horizontally and linearly aligned multicore LED module, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source.

[0246] According to another alternative mode of the embodiment of the present invention, the linear light source 11 is a plurality sets of horizontally and linearly aligned single-chip LED modules.

[0247] According to another alternative mode of the embodiment of the present invention, the linear light source 11 is a plurality sets of horizontally and linearly aligned multicore LED modules, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source.

[0248] The reflective device 70 is a light funnel linear focus reflection structure with a relatively small opening and the linear light source 11 utilizes the reflection surfaces inside of the reflective device 70 for reflection. Preferably, a reflecting layer is coated and provided on the inner surface of the reflective device 70, so as to further enhance the reflectivity and the reflection strength to the light of the linear light source 11.

[0249] Specifically speaking, the reflective device 70 comprises a reflection light funnel 71 and two reflection extension portions 72 that have same structure and are spacingly arranged. The reflection light funnel 71 forms, provides, and defines a cavity 700 therein. The light of the linear light source 11 is projected into the internal of the reflection light funnel 71 to be reflected. Then the reflected light will be emitted from the opening. Each of the reflection extension portions 72 comprises a first section 721 and a second section 722. The first section 721 of the reflection extension portion 72 extends outward from the two sides of another end of the reflection light funnel 71 along the illumination direction of the linear light source 11 and closes inward to form the second section 722. In other words, a second angle α2 is created between the first section 721 and the second section 722 of the reflection extension portion 72 and a first angle α1 is created between the first section 721 of the reflection extension portion 72 and the reflection light funnel 71.

[0250] The scope of the first angle α1 is 90°-270°, and preferably 225°. The scope of the second angle α2 is 0°-180°, which can be, for instance, 150°. An opening that opens outward can be formed between it and the reflection light funnel 71. The angle between the reflection light funnel 71 and the first section 721 of the reflection extension portion 72 can be, for instance, 225°. In other words, two of the reflection extension portions 72 are respectively extended outward from the two sides of the reflection light funnel 71 for such as 45° and closed inward respectively for such as 30°, so as to form, for instance, 225° between the first section 721 of the reflection extension portion 72 and the reflection light funnel 71 and form, for instance, 150° between the first section 721 and the second section 722 of the reflection extension portion 72.

[0251] In detail, the reflection light funnel 71 comprises a horizontal linear reflecting surface 711 and a light spreading cambered surface 712 respectively arranged on the upper surface and the lower surface of the internal thereof. The horizontal linear reflecting surfaces 711 and the light spreading cambered surfaces 712 are both utilized for reflecting the light of the first linear light source 11. The horizontal linear reflecting surface 711 is close to the linear light source 11. The light spreading cambered surface 712 is extended from the horizontal linear reflecting surface 711 and away from the side of the linear light source 11. The reflection light funnel 71 comprises an ellipse line reflecting side 713 and a non-ellipse line reflecting surface 714 respectively arranged on the two sides in the internal thereof. The ellipse line reflecting surface 713 and the non-ellipse line reflecting surface 714 are both utilized for reflecting the light of the linear light source 11. The ellipse line reflecting surface is close to the side of the linear light source 11. The non-ellipse line reflecting surface 714 is extended from the ellipse line reflecting surface 713 and away from the side of the linear light source 11. In other words, the reflection light funnel 71 comprises a horizontal linear reflecting surface 711 and a light spreading cambered surface 712 respectively arranged on the upper surface and the lower surface of the internal thereof. The horizontal linear reflecting surface 711 is formed by stretching mainly on the basis of ellipse lines and partially on the basis of non-ellipse lines. The light of the linear light source 11 is converged on the linear focus F2 by the horizontal linear reflecting surface 711, so as to enhance the light intensity of the center. The light spreading cambered surface 712 is mainly to shift part of the light of the linear light source 11 upward from the linear focus F2, so as to increase the light distribution to the ground illumination. The reflection light funnel 71 comprises an ellipse line reflecting surface 713 and a non-ellipse line reflecting surface 714 respectively arranged and extended along the length direction on the left side and the right side of the internal thereof. The function of the ellipse line reflecting surface 713 and the non-ellipse line reflecting surface 714 is to reflect and converge the light of the linear light source 11 on the linear focus F2.

[0252] Because the second section 722 of the reflection extension portion 72 is bent inward, the inner surface of the second section 722 of the reflection extension portion 72 will involve in the reflection of the light of the first linear light source 11. The inner surface of the second section 722 of the reflection extension portion 72 is a plane that inclines inward for a certain angle. In other words, the reflection extension portion 72 comprises a reflection surface 7221, mainly formed by a plane inclining inward for a certain angle, for being a collecting surface, so as to reflect the light projected from the linear light source 11 to the condenser lens 13. Then the light will be refracted by the condenser lens 13 to the ground area of a wide angle. In addition, the light emitted by the linear light source 11 beyond the subtended angle of the condenser lens 13 can be reflected by the reflection surfaces 7221, so as to be converged again on the condenser lens 13 for being refracted to the illumination area of the left and right sides, such as a 40° illumination area and etc..

[0253] For the low beam headlamp of the present invention, the cut-off screen 14 comprises a base plate 141 and a shading baffle 142. The shading baffle 142 is a shading layer, so the shading area of the shading baffle 142 does not have reflecting coating thereon. Besides, the cut-off screen 14 and the reflective device 70 are integrally connected. As an option, the cut-off screen 14 and the reflective device 70 may also be dismantably connected, as long as it can achieve the same or similar technical effect to the present invention, wherein the specific implementations or practices of the present invention shall not be limited hereby.

[0254] It should be noted that because the opening of the reflective device 70 is relatively small and the reflecting surfaces disposed internally is deep, the reflective device 70 is arranged to include two symmetrical structures, the reflection unit 70a and the reflection unit 70b, in order for coating the reflection layer for the reflecting surfaces. The reflection unit 70a and the reflection unit 70b are respectively mounted and arranged in the top and bottom sides of the linear light source 11 so as to reflect the light of the linear light source 11. This arrangement is able to reduce the part types of the product and therefore lower the costs of the low beam headlamp.

[0255] Similarly, the reflective device 70 may also be longitudinally divided into two symmetrical portions that are replaceable to each other, which is helpful for coating reflecting layer on the reflecting surfaces in the reflective device 70. Besides, it can also reduce the part types of the product and therefore enhance productivity. Besides, the material of the reflection layer of the reflecting surfaces of the reflective device 70 can be selected, based on actual needs, from the materials such as metal coating, alloy coating, compound coating, and etc.. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0256] In summary, because the opening of the reflective device 70 is relatively small, the light of the linear light source 11 projected from the opening will directly be converged on the condenser lens 13 to be refracted to the ground. Therefore, it can fully collect the light projected from the linear light source 11 in the 360° scope, which means relatively high light collection. As a result, it is able to not only increase the brightness of the low beam headlamp, but also decrease the power consumption of the entire lamp. Besides, it can distribute the light projected from the linear source 11 for linear focuses, so as to concentrate the beam on the horizontal axis, which distributes more light for the distant place of the vehicle and makes the illumination vision farther, wider, and brighter.

[0257] Referring to Figs. 23-24, the headlamp further comprises an outer cover 30, an outer lens 50, and a metal heat dissipation body 40, wherein the outer cover 30 is utilized for protecting the low beam headlamp and extending the service life of the headlamp. Also, the outer cover 30 can shade and keep the scattered light emitted by the headlamp in the internal thereof. The outer lens 50 is affixedly connected with the front end of the outer cover 30 to further refract the light emitted by the low beam headlamp, so as to enhance the illuminating effect of the headlamp.

[0258] Referring to Fig. 24, the outer cover 30 comprises a first portion 31 and a second portion 32. The first portion 31 and the second portion 32 are connected to form an accommodation cavity 300 for accommodating the optical system of the headlamp. The second portion 32 acts as the back end. The metal heat dissipation body 40 is disposed inside of the second portion 32. The first portion 31 acts as the front end and comprises an opening 310. The opening 310 is utilized for placing the condenser lens 13 and for the light of the linear light source 11 to pass through.

[0259] Preferably, the outer lens 450 is affixedly connected with the front end of the outer cover 30 and connected with the low beam headlamp through sealant, such that the low beam headlamp can be waterproof and dustproof. The linear light source 11 of the low beam headlamp can be directly affixed on the metal heat dissipation body 40. Because the heat transmission speed of the metal heat dissipation body 40 is fast, the arrangement of the metal heat dissipation body 40 can avoid service life decrease of the first linear light source 11 due to rapid temperature increase or failure of timely heat dissipation.

[0260] Preferably, the low beam headlamp further comprises a metal heat dissipation board 60. The linear light source 11 is directly affixed on the metal heat dissipation board 60 through welding, soldering, screwing or other means. Preferably, the heat conduction surface of the LED of the linear light source 11 is directly mounted on the metal heat dissipation board 60 having a large size. The surface area of the metal heat dissipation board 60 is big, which benefits to heat dissipation. The linear light source 11 affixed and welded on the metal heat dissipation board 60 is then affixedly connected with the metal heat dissipation body 40. Because the contacted area of the metal heat dissipation board 60 and the metal heat dissipation body 40 is big, it can therefore further enhance the heat dissipation of the first linear light source 11, so as to extend the service life of the low beam headlamp.

[0261] Referring to Figs. 27-30, the present invention further provide a headlamp, which comprises at least a linear light source 21, at least a reflective device 80, and at least a condenser lens 13. The reflective device 80 reflects at least part of the light emitted by the linear light source 21. At least part of the light of the linear light source 21 reflected by the reflective device 80 will be converged on a linear focus F2. The condenser lens 13 is mounted, arranged, and provided in front of the linear focus F2, so as to utilize lens principles to converge the light of the linear focus F2 into a horizontal linear high density light spot.

[0262] Specifically speaking, the linear light source 21 is embodied as a plurality of LEDs 211. The LEDs 211 can be five-chip LED module of 1500Lm, and 5700K color temperature arranged in the middle and two single-chip ceramic packaged LEDs 211 of 250Lm, warm white, and 3000K color temperature respectively arranged in both the left and right, which hybridly utilizes white light and warm white light to lower the color temperature of the complete lamp, which enhances the penetrability of the light under foggy day and rainy day and makes the state of roads more clear. All the LEDs 211 are arranged in a horizontal linear manner and coincide with the focus of the first reflective device.

[0263] According to another alternative mode of the embodiment of the present invention, the linear light source 21 is a set horizontally and linearly aligned multicore LED module, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source.

[0264] According to another alternative mode of the embodiment of the present invention, the linear light source 21 is a plurality sets of horizontally and linearly aligned single-chip LED modules.

[0265] According to another alternative mode of the embodiment of the present invention, the linear light source 21 is a plurality sets of horizontally and linearly aligned multicore LED modules, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source.

[0266] The reflective device 80 is a light funnel linear reflector with a relatively small opening and the linear light source 21 utilizes the reflection surfaces inside of the reflective device 80 for reflection. Preferably, a reflecting layer is coated and provided on the inner surfaces of the reflective device 80, so as to further enhance the reflectivity and the reflection strength to the light of the linear light source 21.

[0267] Specifically speaking, the reflective device 80 comprises a reflection light funnel 81 and reflection extension portions 82. The reflection light funnel 81 forms, provides, and defines a cavity 800 therein. The linear light source 21 is able to project light into the internal of the reflection light funnel 81 to be reflected. Then the reflected light will be emitted from the opening of the reflection light funnel 81. The reflection extension portion 82 comprises two reflection collecting sections 821 that have basically the same structure and are spacingly arranged. The two reflection collecting sections 821 are respectively extended outward along the illumination direction of the linear light source 21 on two sides of an end of the reflection light funnel that is away from the linear light source 21 and are bent outward. In other words, each of the reflection collecting sections 82 respectively forms and defines an included angle β with the reflection light funnel 81.

[0268] The included angle β is 90°-270° or, for example, 210°. In other words, two of the reflection collecting section 82 are respectively extended outward from the reflection light funnel 81 and bent outward for 30°, so as to form the included angle β.

[0269] In detail, the reflection light funnel 81 comprises a horizontal linear reflecting surface 811 and a light spreading cambered surface 812 respectively arranged on the upper surface and the lower surface of the internal thereof. The horizontal linear reflecting surface 811 is adjacent to the linear light source 21. The light spreading cambered surface 812 is extended from the horizontal linear reflecting surface 811 and is positioned on the side that is away from the linear light source 21. The horizontal linear reflecting surface 811 and the light spreading cambered surface 812 are both utilized for reflecting the light of the linear light source 21. The horizontal linear reflecting surface 811 is mainly formed by horizontally stretching the combination line mainly of the basis of ellipse lines and partially of the basis of non-ellipse lines. The light spreading cambered surface 812 is mainly to shift part of the light of the linear light source 21 upward from the linear focus F2, so as to enhance the light distribution of ground illumination.

[0270] The surfaces of the two internal sides of the light funnel 81 are mirror surfaces 813 that are based on planes to mirror and reflect the light of the linear light source 21 to the horizontal linear reflecting surfaces 811 or the mirror surfaces 813 of the opposite side so as to eventually reflect the light to the linear focus F2.

[0271] It is worth noticing that the reflection light funnel 81 further comprises a curvy groove 810. The surface of the curvy groove 810 is a middle partial rotating reflecting surface 814. The middle partial rotating reflecting surface 814 is formed between the upper surface and lower surface of the internal of the reflection light funnel 81 and is arranged along the emission direction of the linear light source 21. The middle partial rotating reflecting surface 814 is a partial rotating surface, which is mainly formed by rotating the combination lines of the main basis of ellipse line and partial basis of non-ellipse line.

[0272] The inner surface of the reflection collecting section 82 involves in the reflection of the light emitted by linear light source 21. Therefore, each of the two reflection collecting section 82 comprises a collecting surface 821 arranged on the inner surface thereof. The collecting surface 821 is mainly formed by plane and is inclined outward for a certain angle, so as for reflecting the light emitted by the linear light source 21 to the condenser lens 23. Then the light can be refracted through the second condenser lens 23 to the ground area of a wide angle of the left and right.

[0273] In summary, because the opening of the reflective device 80 is relatively small, the light of the linear light source 21 projected from the opening will directly be converged on the condenser lens 23 to be refracted to the ground. Therefore, it can fully collect the light projected from the linear light source 21 in the 360° scope, which means relatively high light collection. As a result, it is able to not only increase the brightness of the headlamp, but also decrease the power consumption of the entire lamp. Besides, it can distribute the light projected from the linear light source 21 for linear focuses, so as to concentrate the beam on the horizontal axis for the implementation of a high beam headlamp, which distributes more light for the distant place of the vehicle and makes the illumination vision farther, wider, and brighter.

[0274] When the above mentioned headlamp of the present invention is embodied as a high beam headlamp, the high beam headlamp further comprises an anti-glare board 24. The anti-glare board 24 is arranged at the position of the linear focus F2. Referring to Fig. 28, the anti-glare board 24 comprises a base 241 and an anti-glare baffle 242. The anti-glare baffle 242 comprises an opening 2420 arranged thereon for the light of the second linear light source 21 to pass through to form the high beam light spot. The opening 2420 may, based on actual needs or customer requests, be arranged into the shape of triangle, rectangle, circle, or any other shape. As long as it achieves the same or similar effect or result to the present invention, it shall be in the scope of the present invention. Namely, the implementation or practice of the present invention shall not be limited thereby.

[0275] The anti-glare zone I must have a certainly brightness, but it must also have a limit, so as to prevent glare without affecting the observation of the state of roads. Besides, the upper 3° Line 1 in the middle has a minimum and maximum brightness requirement, so as to ensure there is sufficient brightness for seeing the street sign above clearly, but not to render glare and dazzle to the pedestrians and drivers of the opposite side when the vehicle is turning. The anti-glare board 24 is made of a transparent, opaque semi-transparent material or a dichroic glass. The opaque anti-glare board 24 is utilized to shade and block the light of the glare zone. The transparent and semi-transparent anti-glare board 24 has part of the area thereof be coarsened or granulated, so as to weakened the light of the glare zone. The dichroic glass without electrifying has disorder molecular arrangement in the liquid crystal membrane thereof obstructing the light so as to allow the dichroic glass to weaken the light. Dichroic glass with electrifying has ordered molecular arrangement in the liquid crystal membrane thereof allowing more light to pass through the dichroic glass.

[0276] It should also be noted that because the opening of the reflective device 80 is relatively small and the reflecting surfaces disposed internally are deep, the reflective device 80 is arranged to include two portions, which are the upper reflection unit 80a and the lower reflection unit 80b, in order for coating the reflection layer for the reflecting surfaces. As a result, it can reduce the part types of the product and therefore lower the costs of the high beam headlamp.

[0277] Similarly, the reflective device 80 may also be longitudinally divided into two symmetrical portions that are replaceable to each other, which is helpful for coating reflecting layer on the reflecting surfaces in the reflective device 80. Besides, it can also reduce the part types of the product and therefore enhance productivity. Besides, the material of the reflection layer of the reflecting surface of the reflective device 80 can be selected based on different usage requirements, from the materials such as metal coating, alloy coating, compound coating, and etc.. The reflective device 80 can be provided as an integral structure based on the needs. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0278] For the high beam headlamp according to this embodiment of the present invention, because the reflective device 80 has higher optical density, smaller size, an anti-glare system that is favor of liquid crystal lattice, and smaller liquid crystal display panel, the anti-glare board of the high beam system is a high density lattice liquid crystal display panel, and both the positions of the lattice of the liquid crystal display panel and the bright/dark lattice arrangement and appearance above the horizontal line can be controlled through circuits, it can achieve an anti-glare result.

[0279] It is understandable that this headlamp of the present preferred embodiment may also be embodied as a low beam headlamp if the anti-glare board 24 is replaced by the cut-off screen.

[0280] Referring to Figs. 27-28, the headlamp further comprises an outer cover 30, an outer lens 50, and a metal heat dissipation body 60, wherein the outer cover 30 affixes the condenser lens 23 so as for protecting the high beam headlamp and extending the service life of the high beam headlamp. The outer lens 50 is affixedly connected with the front end of the outer cover 30 to further refract the light emitted by the high beam headlamp, so as to enhance the illuminating effect of the high beam headlamp.

[0281] Referring to Fig. 28, the outer cover 30 comprises a first portion 31 and a second portion 32. The first portion 31 and the second portion 32 form an accommodation cavity 300 for accommodating the high beam headlamp. The second portion 32 acts as the back end. The metal heat dissipation body 40 is disposed inside of the second portion 32. The first portion 31 acts as the front end and comprises an opening 310. The opening 310 is utilized for placing the condenser lens 23 and for the light of the linear light source 21 to pass through.

[0282] Preferably, the outer lens 450 is affixedly connected with the front end of the outer cover 430 through sealant, such that the headlamp can be waterproof and dustproof. The linear light source 21 of the high beam headlamp can be directly affixed on the metal heat dissipation body 40. Because the heat transmission speed of the metal heat dissipation body 40 is fast, the arrangement of the metal heat dissipation body 40 can avoid service life decrease of the linear light source 21 due to rapid temperature increase or failure of timely heat dissipation.

[0283] Preferably, the headlamp further comprises a metal heat dissipation board 60. The linear light source 21 is directly affixed on the metal heat dissipation board 60 through welding, soldering, screwing or other means. Preferably, the heat conduction surface of the LED of the linear light source 21 is directly mounted on the metal heat dissipation board 60 having a large size. The surface area of the metal heat dissipation board 60 is big, which benefits to heat dissipation. The linear light source 21 affixed and welded on the metal heat dissipation board is then affixedly connected with the metal heat dissipation body 40. Because the contacted area of the metal heat dissipation board 60 and the metal heat dissipation body 40 is big, it can therefore further enhance the heat dissipation of the linear light source 21, so as to extend the service life of the high beam headlamp.

[0284] Referring to Figs. 31-37, the present invention further provides a method for providing low beam light spot, comprising the following steps:

emitting light L with a linear light source 11

a reflective device 70 reflecting the light L emitted by the linear light source 11;

a condenser lens 13, refracting the light L emitted by the linear light source 11;

[0285] The light L emitted by the linear light source 11 comprises a first part light L1 and a second part light L2. The first part light L1 will be reflected by the reflective device 70 to the condenser lens 13 to be refracted. The second part light L2 will be directly projected to the condenser lens 13 to be refracted, so as to eventually form a low beam light spot.

[0286] Further, the illumination method of the low beam lamp comprises a step of:

[0287] The light above the light and shade cut-off line of the first part light L1 being reflected by the reflective device 70 will be shaded by the cut-off screen 14.

[0288] Moreover, according to the illumination method of the low beam lamp, a reflecting layer is coated and plated on the reflecting surface of the first reflective device 70, so as to enhance the reflection efficiency of the first reflective device 70. The material of the reflection layer of the reflecting surface can be selected based on different usage requirements, from the materials such as metal coating, alloy coating, compound coating, and etc.. The reflective device 70 can be provided as an integral structure. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0289] More specifically, referring to Fig. 32, the reflecting surface of the first reflective device 70 is formed and constructed by a middle horizontal linear reflecting surface 711, a light spreading cambered surface 712, an ellipse line reflecting surface 713, a non-ellipse line reflecting surface 714, and a collecting surface 715. The middle horizontal linear reflecting surface 711 is a surface formed by stretching the combination lines mainly based on ellipse line and partially based on non-ellipse line. The light of the first linear light source 11 is converged on the linear focus F2 through it, so as to enhance the central light intensity. The light of the linear light source 11 is converged by the ellipse line reflecting surface 713 and the non-ellipse line reflecting surface 714 on the linear focus F2. The light spreading cambered surface 712 is mainly to shift part of the light upward from the linear focus F2, so as to enhance the light distribution of ground illumination. The collecting surface 715 is mainly formed by plane and inclined inward for a certain angle, so as to reflect the light to the condenser lens 13. Then the light will be refracted by the condenser lens 13 to a ground, area for a wide angle of left and right. Because the opening of the first reflective device 70 is relatively small, the light of the linear light source 11 can be directly emitted from the opening and directly pass through the condenser lens 13 to be refracted to the ground. In other words, the first reflective device 70 can fully collect the light emitted by the first linear light source 11 in 360° three-dimensionally. Such high light collection can enhance the brightness of the lamp, so as to reduce the power dissipation and consumption of the whole lamp. Besides, it can also distribute the light emitted by the first linear light source 11 to the linear focus F2 to concentrate the light on the horizontal axis, which distribute more light for the distant place of the vehicle, so as to extend the illumination vision and make the width direction wider and brighter.

[0290] As mentioned above, according to this embodiment of the present invention, the first part light L1 reflected by the first reflective device 70 comprises the following portions:

part of the light L11 is reflected to the condenser lens 13 by the middle horizontal linear reflecting surface 711;

part of the light L12 is reflected to the condenser lens 13 by the light spreading cambered surfaces 712;

part of the light L13 is reflected to the condenser lens 13 respectively and orderly by the ellipse line reflecting surface 713 and the middle horizontal linear reflecting surface 711;

part of the light L14 is reflected to the condenser lens 13 by the non-ellipse line reflecting surface 714; and

part of the light L15 is reflected to the condenser lens 13 by collecting surface 715. Here, the second part light L2 and the parts of the light L11-L14 are all within the scope of the subtended angle of the condenser lens 13, while part of the light L15 emerges out of the scope of the subtended angle of the condenser lens 13.

[0291] The excess part of light will be blocked and shaded by the cut-off screen 14 from emerging outward, so as to make a light and shade cut-off line for the low beam light spot.

[0292] It utilizes the function of arrangement of the reflective device and the cut-off screen 14 with the condenser lens 13, to increase the width of left and right of the low beam lamp from ten thousand cd to 18° each for the left and right sides, so as to satisfy the demand of wider and brighter sight. Besides, the light intensity of the central zone has been increased to more than fifty thousand cd, which extends the illumination distance of the central zone for the right-hand traffic. Meanwhile, its light and shade cut-off line is clear, which helps to avoid glare and dazzle for the opposite drivers and pedestrians.

[0293] In other words, the part of the light L11 of the first part light L1 emitted by the linear light source 11 is reflected by the horizontal linear reflecting surfaces 711 in the middle to the condenser lens 13 to be refracted. The part of the light L12 of the first part light L1 emitted by the linear light source 11 is reflected by the light spreading cambered surfaces 712 to the condenser lens 13 to be refracted. The part of the light L13 of the first part light L1 emitted from the linear light sources 11 will be reflected by the ellipse line reflecting surfaces 713 to the horizontal linear reflecting surfaces 711 in the middle to be reflected. Then the light will hit the condenser lens 13 to be refracted. The part of the light L14 of the first part light L1 emitted by the linear light source 11 will be reflection by the non-ellipse line reflecting surfaces 714 to the condenser lens 13 to be refracted. The part of the light L15 of the first part light L1 emitted by the linear light source 11 will be reflected by the collecting surfaces 715 to the condenser lens 13 to be refracted. The second part light L2 emitted from the linear light source 11 will directly hit the condenser lens 13 to be refracted, so as to form the low beam light spot. The excess part of light will be blocked and shaded by the cut-off screen 14 from emerging outward, so as to make a light and shade cut-off line for the low beam light spot.

[0294] Referring to Figs. 38-44, the present invention further provides a method for providing high beam light spot, comprising the following steps:

emitting light M with a linear light source 21;

utilizing a reflective device 80 to reflect the light M emitted by the linear light source 21;

utilizing a condenser lens 23 to refract the light M emitted by the linear light source 21;

[0295] Here, the light M emitted by the linear light source 21 comprises a first part light M1 and a second part light M2. The first part light M1 will be reflected by the reflective device 80 to the condenser lens 23 to be refracted. The second part light M2 emitted by the second linear light source 21 will be directly projected to the condenser lens 23 to be refracted, so as to eventually form a high beam light spot.

[0296] Further, the illumination method of the high beam lamp also comprises a step of:
providing an anti-glare board 24, so as to arrange an anti-glare zone for the light emitted by the high beam lamp. Here, the anti-glare board 24 is provided and arranged at the linear focus F2.

[0297] All in all, the first part light M1 passes the reflective device 80 through the following routes:

[0298] Reflecting part of the light M11 being emitted from the linear light source 21 to the condenser lens 23 by the horizontal linear reflecting surfaces 811;

[0299] Reflecting part of the light M12 being emitted from the linear light source 21 to the condenser lens 23 by the light spreading cambered surfaces 812;

[0300] Reflecting part of the light M13 being emitted from the linear light source 21 to the mirror surfaces 813 to be reflected to the condenser lens 23 or to the horizontal linear reflecting surfaces 811 or the mirror surfaces 813 in the opposite side to be projected to the condenser lens 23;

[0301] Reflecting part of the light M14 being emitted from the linear light source 21 to the condenser lens 23 by the middle partial rotating reflecting surface 814;

[0302] Reflecting part of the light M15 being emitted from the linear light source 21 to the condenser lens 23 by the collecting surfaces 821;The second part light M2 and the parts of the light M11-M14 of the first part light M1 are all within the scope of the subtended angle of the condenser lens 23, while part of the light M15 emerges out of the scope of the subtended angle of the condenser lens 23.

[0303] Next, it will further and simply disclose operating principles of the high beam lamp.

[0304] The part of the light M11 of the first part light M1 emitted by the linear light source 21 is reflected by the horizontal linear reflecting surfaces 811 to the condenser lens 23 to be refracted. The part of the light M12 of the first part light M1 emitted by the linear light source 21 is reflected by the light spreading cambered surfaces 812 to the condenser lens 23 to be refracted. The part of the light M13 of the first part light M1 emitted from the linear light source 21 will either be reflected by the mirror surfaces 813 to the horizontal linear reflecting surfaces 811 or to the mirror surfaces 813 in the opposite side to be reflected to the condenser lens 23 to be refracted, or be reflected by the mirror surfaces 813 to the condenser lens 23 to be refracted. The part of the light M14 of the first part light M1 emitted by the linear light source 21 will be reflection by the middle partial rotating reflecting surface 814 to the condenser lens 23 to be refracted. The part of the light M15 of the first part light M1 emitted by the linear light source 21 will be reflected by the collecting surfaces 821 to the condenser lens 23 to be refracted. The second part light M2 emitted by the linear light source 21 will directly hit the condenser lens 23 to be refracted, so as to form the high beam light spot. It should be noted that the part of the lights M1 1-M14 of the first part light M1 can be converged on the linear focus F2 after being reflected by the reflective device 80, such that the illuminating effect of the high beam lamp can be enhanced.

[0305] Referring to Figs. 45-52, the lighting system integrating high and low beams according to a second embodiment of the present invention, comprises at least a linear light source 411 and at least a linear focus reflector 412 wherein the position of the linear light source 411 coincides with a linear focus F1 of the linear focus reflector 412, wherein the linear focus reflector 412 is adapted to converge part of the light of the linear light source 11 on a linear focus F2, so as to allow the lighting system integrating high and low beams to produce a low beam light spot and a high beam light spot.

[0306] Preferably, an integral lighting system of the present invention further comprising at least a condenser lens 413 arranged in front of the linear focus F2. Further, it also comprises a cut-off screen 414 and a solenoid valve 416. The cut-off screen 414 is mounted on the linear focus reflector 412 and arranged along the linear focus F2. Also, the cut-off screen 414 and the solenoid valve 416 are affixedly connected with each other. When the cut-off screen 414 is rotated at the linear focus F2 through the solenoid valve 416, so as to allow the light emitted by the linear light source 411 or the light reflected by the linear focus reflector 412 will be partially shaded and blocked by the cut-off screen 414, while part of the light will pass the area of the cut-off screen 414 and be refracted by the condenser lens 413 to form the low beam light spot or high beam light spot.

[0307] In detail, according to the above second embodiment of the present invention, the lighting system integrating high and low beams can be utilized for the illumination of a conveyance. The conveyance can be a road surface conveyance, such as a vehicle and etc., a water conveyance, such as a boat, a ship, and etc. or an air conveyance. The linear focus reflector is utilized for conducting reflection for the linear light source. The linear light source 411 is perpendicular to the optic axis of the system and is horizontally and linearly aligned and coincides with the linear focus F1 of the linear focus reflector 412. At least part of the light emitted by the linear light source 411 is reflected by the linear focus reflector 412 to be converged on another linear focus F2 of the linear focus reflector 412. The condenser lens 413 is mounted, arranged, and provided in front of the linear focus F2, so as to utilize lens principles to converge the light passing the linear focus F2 into a horizontal linear high density light spot. The cut-off screen 414 is mounted, arranged, and provided at the position of the linear focus F2, so as to shade and block the light above the cut-off line of the cut-off screen 414 and to allow part of the light to pass by above the cut-off screen 414 to be refracted by the condenser lens in order to form a weak light zone above the cut-off line and therefore form the low beam lamp light spot.

[0308] Specifically, according to the above second embodiment of the present invention, the linear light source 411 is embodied as a plurality of LEDs horizontally aligned. According to an implementation, the LEDs can be five-chip LED module of 1500Lm and 5700K color temperature arranged in the middle and two single-chip ceramic packaged LED of 250Lm, warm white light, and 3000K color temperature respectively in the left and right, which hybridly utilizes white light and warm white light to lower the color temperature of the complete lamp, which enhances the penetrability of the light under foggy day and rainy day and make the state of roads more clear. All the LEDs are arranged in a horizontal linear manner and the illumination direction of the LEDs is the same to the direction of the optic axis of the linear light source 411 and coincides with the focus of the linear focus reflector 412, so as to increase the total luminous flux of the linear light source 411.

[0309] According to another alternative mode of the second embodiment of the present invention, the linear light source 411 may be a set of horizontally and linearly aligned multi-chip LEDs, wherein the LEDs include combinations of white light, warm white light, and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source 411, so as to increase the illumination distance, road surface clarity, and penetrability of the lighting system integrating high and low beams and protect the retina of the driver.

[0310] According to another alternative mode of the above embodiment of the present invention, the linear light source 411 is a plurality sets of horizontally and linearly aligned single-chip LED modules or a LED light source formed by a set of horizontally and linearly aligned single-chip LED module and a set of horizontally and linearly aligned single-chip LED module of a top left or top right half, which is suitable for the low beam lamp optical system.

[0311] In other words, because the focuses F1 and F2 of the linear focus reflector 412 of the present invention are linearly arranged and aligned, the LEDs can also be linearly arranged and aligned and the quantity thereof will not be limited, which can provide a higher optical density and total luminous flux, so as to reduce the electric current of single LED. Hence, the luminous efficiency of the LED will be higher, the illumination width and illumination distance will both be increased as well.

[0312] Referring to Figs. 48-51, according to the above second embodiment of the present invention, the linear focus reflector 412 comprises a main reflection structure 4121 and a subsidiary reflection structure 4122, wherein the main reflection structure 4121 comprises two main reflecting boards 41211 opposite arranged, wherein the subsidiary reflection structure 4122 comprises two subsidiary reflecting boards 41221 that have basically the same structure and are opposite arranged. The two subsidiary reflecting boards 41221 are respectively arranged on the sides of the two main reflecting boards 41211, so as to form a reflecting cavity through the two main reflecting boards 41211 and the two subsidiary reflecting boards 41221. The reflecting cavity has an opening 4120. The light emitted by the linear light source 411 can be emitted from the opening 4120. The linear light source 411 is arranged to horizontally and linearly extend toward the opening 4120, so as to allow the light directly projected from the linear light source 411 out of the opening 4120 without being reflected by the linear focus reflector 412 to directly reach the condenser lens 413 and to be refracted to the road surface. The condenser lens 413 is arranged at the position in front of the linear focus F2 for condensation.

[0313] It is understandable that the linear focus reflector 412 may also be other reflection structure capable of forming the linear focus F1 and F2 according to other alternative modes. Namely, it shall not be limited by the above four reflection structures, but may include structures of the reflecting board other quantities or shapes.

[0314] In addition, each the subsidiary reflecting board 41221 comprises a main portion 412211 and an extension portion 412212. The main portion 412211 and the main reflecting board 41211 form and define the reflecting cavity. The inner side of the main portion 412211 comprises a mirror reflecting surface 4122111 for mirroring and reflecting the light emitted by the linear light source 411. The extension portion 412212 further comprises a transition portion 412212a and an extending portion 412212b. The transition portion 412212a is extended upward from the main portion 412211 and bent outward. The transition portion 412212a and the main portion 412211 form and define a first included angle α1 therebetween. The range of the first included angle α1 is 90°-270°. The extending portion 412212b is extended upward from the transition portion 412212a and bent inward. The extending portion 412212b and the transition portion 412212a form and define a second included angle α2 therebetween. The range of the second included angle α2 is 0°-180°.

[0315] It should be noted that, according to the above embodiment of the present invention, the mirror reflecting surface 4122111 is a plane. Moreover, referring to Fig. 53, as an alternative mode, person skilled in the art may also arrange the inner side (that is the mirror reflecting surface 4122111) of the main portion 412211 into a curvy surface. Therefore it will work, as long as there is the mirror reflecting surface 4122111 for reflecting the light emitted by the linear light source 411. In other words, all implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention.

[0316] It is worth noticing that each the main reflecting board 41211 comprises a horizontal linear reflecting surface 412111 and a light spreading cambered surface 412112 arranged on the inner side thereof. For example, the horizontal linear reflecting surface 412111 may be extended from an end of the inner surface of the main reflecting board 41211 of the horizontal linear reflecting surface 412111 that is close to the linear light source 411 to the other end thereof toward the opening 4120. The horizontal linear reflecting surface 412111 is a surface formed by stretching the combination mainly of the basis of ellipse lines and partially of the basis of non-ellipse lines. The light spreading cambered surface 412112 is outward extended from the horizontal linear reflecting surface 412111 and located at the rear part of the main reflecting board 41211. The main portion 412211 of the subsidiary reflecting board 41221 comprises the mirror reflecting surface 4122111. The mirror reflecting surface 4122111 is extended from an end of the internal of the main portion 412211 that is close to the linear light source 411 to the other end toward the opening 4120. Because the extension portion 4122121 is extended outward relatively to the main portion 412211. The inner sides of the transition portion 412212a and the extending portion 412212b of the extension portion 412212 jointly form and define a collecting surface 4122121. The collecting surface 4122121 is positioned on the inner side of the extension portion 412212. The collecting surface 4122121 is also outward inclined to form the second included angle α2 with the main portion 412211. By providing and arranging the collecting surfaces 4122121, the light beyond the subtended angle of the condenser lens 413 can be reflected to the condenser lens 413 to be refracted to a road surface in the front with a wide angle to the left and right through the condenser lens 413. In other words, the lighting system integrating high and low beams of the present invention is able to collect and utilize all the light produced by the linear light source 411 in 360°, which enhances the light collection, so as to achieve effects and advantages of energy saving, durability, and environmental friendliness.

[0317] It is understandable that, according to this embodiment of the present invention, the linear focus reflector 412 is in a light funnel shape. Nevertheless, the linear focus reflector of the present invention shall not be limited in a light funnel shape. Rather, according to some other alternative modes, person skilled in the art may also arranged other shape and outward appearance, such as sphere shape and etc., for the linear focus reflector 412 as long as its internal can provide the above mentioned reflecting surface structure for the linear focus F1 and F2.

[0318] In addition, as an alternative mode of the present invention, the perpendicular cut-off surface of the horizontal linear reflecting surface 412111 is formed by ellipse lines, ellipse lines and part of non-ellipse lines, or a reflecting surface of non-ellipse lines, to reflect the light to the linear focus F2, or a horizontal linear reflecting surfaces 412111 having pellets thereon.

[0319] The horizontal linear reflecting surface 412111 can be linear or linear with slight curve (e.g. within 5 radian) so as for increasing the light distribution vertically.

[0320] Besides, the mirror reflecting surfaces 4122111 of the two sides of the linear focus reflector 412 are respectively based on straight lines. As an alternative mode of the present invention, referring to Figs. 53-54, the mirror reflecting surface 4122111 is a stretching surface formed based on ellipse lines and part of non-ellipse lines, which comprises an ellipse line reflecting surface 4122111a and a non-ellipse line reflecting surface 4122111b or it further has a slight curve (e.g. within 5 radian), so as for increasing the light distribution vertically. Here, the ellipse line reflecting surface 4122111 a is extended from an end of the internal of the main portion 412211 close to the first linear light source 411 to the other end toward the opening 4120. The non-ellipse line reflecting surface 4122112b is outward extended from the ellipse line reflecting surface 4122111a and positioned at the rear end of the internal of the main portion 412211. The extension portion 412212 is extended inward relatively to the main portion 412211. The inner side of the extension portion 412212 is the collecting surface 4122121. The collecting surface 4122121 is positioned, provided, and arranged on the inner side of the extension portion 412212, so the collecting surface 4122121 is also inclined inward to form and define the second included angle α2. The surface shape of each of the collecting surfaces 4122121 is vertical plane, inclined plane, cambered surface, or strip cambered surface.

[0321] Referring to Fig. 48, according to the above second embodiment of the present invention, the shape of the cut-off line forming face of the cut-off screen 414 can be a 15° oblique line, 45° oblique line, 90° right angle or 0° horizontal line. The cut-off screen 414 comprises a horizontal member 414a and a vertical member 414b. An end of the horizontal member 414a and an end of the vertical member 414b are coincided and the horizontal member 414a and the vertical member 414b are arranged perpendicularly to each other, so as to make the cut-off screen 414 be arranged in a L shape approximately. The cut-off screen 414 comprises at least a rotating hole 4141, at least a moving slot 4142, at least a windowing groove 4143, and at least a jagged sheet 4144. The cut-off screen 414 is mounted on the linear focus reflector 412 and arranged along the linear focus F2. The jagged sheet 4144 is provided on the cut-off line forming face. The solenoid valve 416 comprises an electromagnetic rod 4161 affixedly arranged on the solenoid valve 416. The moving slot 4142 and the electromagnetic rod 4161 of the solenoid valve 416 are affixedly connected. The rotating hole 4141 is provided at the coinciding end of the horizontal member 414a and the vertical member 414b, in the manner that the cut-off screen 414 is able to rotate along the rotating hole 4141. Hence, when the solenoid valve 416 is driven to drive the electromagnetic rod 4161 to move, the solenoid valve 416 will be able to push the electromagnetic rod 4161 to push the cut-off screen 414 to move along the moving slot 4142. Meanwhile, the cut-off screen 414 will rotate along the rotating hole 4141, so as to allow the light that was shaded by the cut-off screen 414 pass through the cut-off screen 414 to reach the condenser lens 413 to be refracted to eventually form the high beam light spot.

[0322] Referring to Figs. 45-48, the jagged sheet 4144 is in a triangle-like shape and the jagged sheet 4144 has a stretched zigzag structure arranged on the surface thereof for reducing the proportion of the blue light at the cut-off line as well as for modifying the light projected to the jagged sheet 4144 to prevent the reflected and diffused reflected light from being projected to the condenser lens 413, so as to make the light and shade cut-off line being formed more clear.

[0323] It should be noted that, according to the above second embodiment of the present invention, because the opening of the linear focus reflector 412 is relatively small and the reflecting surfaces in the inside are deep, in order for coating and plating the reflection layer on the reflecting surfaces, the linear focus reflector 412 can be arranged to include an upper linear focus reflector 412a and a lower linear focus reflector 412b, which are respectively mounted on the top and bottom sides of the linear light source 411, so as to for conducting reflection for the linear light source 411. The optical structures of the upper linear focus reflector 412a and the lower linear focus reflector 412b are basically the same, which respectively have part of the horizontal linear reflecting surface 412111, the light spreading cambered surface 412112, and the mirror reflecting surface 4122111.

[0324] It should be noted that the alternative mode of the linear focus reflector is for increasing the illumination brightness of wide angle of the left and right of the road surface. The mirror reflecting surface 4122111 of the main portion 412211 can be modified into an ellipse line reflecting surface and a non-ellipse line reflecting surface. The linear light source 411 emits light to the ellipse line reflecting surface and the non-ellipse line reflecting surface to be directly reflected to the condenser lens 413 to be refracted to the ground for a wide angle illumination. Alternatively, it can be modified into a non-ellipse line reflection surface, so as for increasing the width of the left and right of the illumination of the ground.

[0325] Referring to Fig. 48, the windowing groove 4143 is arranged on the horizontal member 414a at approximate center of the horizontal member 414, so as to allow the light projected by the linear light source 411 to pass through the windowing groove 4143. The lighting system integrating high and low beams of the present invention further comprises an optical filter 415 affixedly arranged in the windowing groove 4143 of the cut-off screen 414. The part of the light passing through the cut-off screen 414 will then pass by the optical filter 415 arranged in the windowing groove 4143, so as to weaken the light and diffuse it to the condenser lens 413. Then the light will be refracted by the condenser lens 413 to the dark zone above the cut-off line to form a weak light zone

[0326] (Zone γ) in order to enhance the light intensity of PI to P6 without enhancing the light intensity of P7, P8, B50L and HV testing point, so as to allow the pedestrian of the opposite side to clearly see the passing of the vehicle in the front. The jagged sheet 4144 of the cut-off line forming face can shade the light of large incident angle from the condenser lens 413, so as to reduce the proportion of blue light at the cut-off line and to eliminate the blue light runoff at the cut-off line.

[0327] According to the above preferred embodiment of the present invention, the optical filter 415 may be made of opaque material, semi-transparent material, diffused material, white material, and etc.. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, material of the optical filter of the present invention shall not be limited thereby.

[0328] According to the above embodiment of the present invention, the shape of the windowing groove 4143 is rectangle. The shape and size of the optical filter 415 is the same and matches to the windowing groove 4143, so as to allow the cut-off screen 414 to be affixed in the windowing groove 4143. According to an alternative mode of the present invention, the shape of the windowing groove 4143 may also be embodied as square shape, circular shape, oval shape, and etc., or the shapes of multiple squares, circles, ovals, combinations thereof, and etc.. The shape of the optical filter 415 may also be embodied as square shape, circular shape, oval shape, and etc., or the shapes of multiple squares, circles, ovals, combinations thereof, and etc., or shapes of trademarks and words. Namely, the shape of the optical filter 415 is not limited by the shape and quantity of the windowing groove 415.

[0329] Referring to Fig. 49, according to the present embodiment, the condenser lens 413 is an optical lens for eliminating blue light runoff, which comprises an input optical surface 4133, an output upper optical surface 4131, and an output lower optical surface 4132. More preferably, the input optical surface 4133 of the condenser lens 413 is a plane or non-plane optical surface, the output upper optical surface 4131 is arranged and positioned above the central horizontal axis and is a condensation surface, and the output lower optical surface 4132 is arranged and positioned below the central horizontal axis and is an irregular surface and non-rotating surface.

[0330] Referring to Fig. 50, the central section plane of the output lower optical surface 4132 of the condenser lens 413 can be divided into several optical curves 41321, 41322, 41323......4132*. The parameters of the present invention is as follows: 41321 indicates the light of several optical surfaces laterally will lean slightly downward between 0° to 0.05°, 41322 indicates the light of several optical surfaces laterally will lean slightly downward between 0.05° to 0.1°, 41323 indicates the light of several optical surfaces laterally will lean slightly downward between 0.1° to 0.15°, and 4132* indicates the light of several optical surfaces laterally will lean slightly downward between 0.05 times * degree to 0.05 times * degree. Nevertheless, the parameters may vary.

[0331] It should be noted that the condenser lens 413 act as is an optical lens to eliminate blue light runoff and that the output lower optical surface 4132 is adjusted so as to have the blue light of the output lower optical surface 4132 to be parallel to or lower than the yellow light of the output upper optical surface 4131, such that the yellow light of the output upper optical surface 4131 will completely cover the blue light of the output lower optical surface 4132 and the yellow light of the output lower optical surface 4132 will also completely cover the blue light of the output upper optical surface 4131, which eventually forms a light spot without blue light runoff at the cut-off line.

[0332] In other words, according to the present embodiment, the output lower optical surface 4132 is adjusted so as to have the blue light of the output lower optical surface 4132 to be parallel to or lower than the yellow light of the output upper optical surface 4131, such that the yellow light of the output upper optical surface 4131 will completely cover the blue light of the output lower optical surface 4132 and the yellow light of the output lower optical surface 4132 will also completely cover the blue light of the output upper optical surface 4131, which eventually forms a light spot without blue light runoff at the cut-offline.

[0333] It should be noted that for an optical lens for eliminating the blue light runoff, the light source is a white light LED light source, which produces and mixed white light through phosphor powder stimulated by blue light. Therefore, the light is mainly formed by yellow light and blue light. The refractive indexes of light of different wavelengths are different for the same medium, wherein the longer the wavelength, the smaller the refractive index will be, while the shorter the wavelength, the larger the refractive index will be. Therefore, after the lights L4101...L4102...L4103 that pass through F1 have passed through the input optical surface 4133, they will be refracted into blue light portions L4101B...L4102B...L4103B and yellow light portions L4101Y...L4102Y...L4103Y. The bigger the incident angle of the blue light, the bigger the deviation angle thereof will be. Then the lights will be refracted through the output upper optical surface 4131 and divided into downward inclined portions L4101B'...L4102B'...L4103B' and parallel lights L4101Y'...L4102Y'...L4103Y'. After the lights L4201...L4202...L4203 that pass through F1 have passed through the input optical surface 4133, they will be refracted into blue light portions L4201B...L4202B...L4203B and yellow light portions L4201Y...L4202Y...L4203Y. The bigger the incident angle of the yellow light, the bigger the deviation angle thereof will be. Then the lights will be refracted through the output optical surface 4132 and divided into parallel lights L4201B'...L4202B'...L4203B and downward inclined portions L4201Y'...L4202Y'...L4203Y'. The parallel lights L4101Y'...L4102Y'...L4103Y' and the parallel lights L4201B' ...L4202B' ...L4203B' are mixed to form a light spot without blue light runoff, while the downward inclined portions L4101B'...L4102B'...L4103B' and the downward inclined portions L4201Y'...L4202Y'...L4203Y' are mixed to form a light spot without blue light runoff as well, so as to eventually eliminate the blue light runoff from the light spot at the cut-off line.

[0334] As an option, either one or both of the output lower optical surface 4132 or the output upper optical surface 4131 may be a modified curved surface(s). Alternatively, the input optical surface 4133 can be a modified curved surface.

[0335] Hence, referring to Fig. 55, the operating principles of the lighting system integrating high and low beams according to the above second embodiment of the present invention include:

[0336] Part of the light emitted by the linear light source 411 will be reflected one or more times by the linear focus reflector 412 and then hit the cut-off screen 414. The cut-off screen 414 will shade the portion of the light above the cut-off line, while the rest of the light will reach the condenser lens 413 to be refracted, so as to form and produce the low beam light spot.

[0337] Another part of the light emitted by the linear light source 411 will directly hit the cut-off screen 414. The cut-off screen 414 will then shade the portion of the light above the cut-off line, while the rest of the light will reach the condenser lens 413 to be refracted, so as to form and produce the low beam light spot.

[0338] Then it drives the solenoid valve 416. Due to the drive of the solenoid valve 416, the electromagnetic rod 4161 will bring the cut-off screen 414 to rotate, so as to allow the light that was shaded by the cut-off screen 414 as mentioned above to fully reach the condenser lens 413 to be refracted, so as to form the high beam light spot. Hence, it may quickly implement the switching of the high beam effect and the low beam effect by driving the solenoid valve 416 to restore and reposition to switch between the high beam light spot and the low beam light spot again.

[0339] Referring to Figs. 58 and 59, the lighting system integrating high and low beams further comprises an outer cover 430. The outer cover 430 comprises a first portion 431 and a second portion 432. The first portion 431 and the second portion 432 form an accommodation cavity 4300 for accommodating the high beam headlamp. The second portion 432 acts as the back end. The metal heat dissipation body 440 is disposed inside of the second portion 432. The first portion 431 acts as the front end and comprises an opening 4310. The opening 4310 is utilized for placing the condenser lens 413 and for the light of the linear light source 411 to pass through. The outer cover 430 can shade and keep the scattered light emitted by the linear light source 411 in the internal of the accommodation cavity 4300, so as to enhance the illuminating effect of the lighting system integrating high and low beams.

[0340] The lighting system integrating high and low beams further comprises an outer lens 450, affixedly arranged on the front section of the outer cover 430, such that the headlamp can be waterproof and dustproof. The light emitted by the linear light source 411 will be refracted by the condenser lens 413 and then further be refracted by the outer lens 450. According to this embodiment of the present invention, the outer lens 450 is affixedly connected with the front end of the outer cover 430 through sealant, so as to form a complete piece of the lighting system integrating high and low beams.

[0341] According to the embodiment of the present invention, the outer lens 450 is affixedly connected with the front end of the outer cover 430 through sealant, so as to achieve a waterproof and dustproof effect for the linear light source 411, the linear focus reflector 412, the cut-off screen 414, the solenoid valve 416, and the optical filter 415. Nevertheless, the embodiment and practice of the present invention shall be limited thereby. Person skilled in the art is able to utilize any means to affix the outer lens 450 on the front end of the outer cover 430 based on the above disclosed notions. All implementations that utilize the same similar technology to the present invention, solve the same or similar technical issue the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0342] Moreover, the present invention further comprises a front position lamp optical lens 492 and a front position lamp light source unit 491, wherein the front position lamp optical lens 492 and the front position lamp light source unit 491 are sequentially affixed between the outer lens 450 and the outer cover 430, so as to further enhance the illuminating effect of the lighting system integrating high and low beams.

[0343] The present invention further comprises a heat dissipation body 440. The heat dissipation body 440 is preferably made of metallic material, so as to enhance the heat dissipation effect of the heat dissipation body. The linear light source 411 is affixedly connected with the heat dissipation body 440, so as to dissipate the heat produce by the linear light source 411. Meanwhile, the heat dissipation body 440 and the outer cover 430 are affixedly connected through sealant. The linear light source 411 of the lighting system integrating high and low beams can be directly affixed on the heat dissipation body 440. Because the heat transmission speed of the heat dissipation body 440 is fast, the arrangement of the heat dissipation body 440 can avoid service life decrease of the linear light source 411 due to rapid temperature increase or failure of timely heat dissipation.

[0344] The present invention further comprises a metal heat dissipation board 460, wherein the heat conduction surface of the linear light source 411 is affixedly mounted and arranged on the metal heat dissipation board 460, so as to enhance the heat dissipation of the linear light source 411.

[0345] Moreover, person skilled in the art may, based on the above disclosure and actual circumstances, decide the specific structure and material of the heat dissipation body 440. All implementations that utilize the same similar technology to the present invention, solve the same or similar technical issue the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0346] Referring to Fig. 57, the present invention further provide a illumination method for lighting system integrating high and low beams, wherein Fig. 57 is a flow diagram of the illumination method, comprising the following steps:

emitting light L with the linear light source 411;

reflecting the light L emitted by the linear light source 411 with the linear focus reflector 412;

utilizing the condenser lens 413 to refract the light L emitted by the linear light source 411, wherein the light L emitted by the linear light source 411 comprises a first part light L41 and a second part light L42. The first part light L41 will be reflected by the linear focus reflector 412 to the condenser lens 413 to be refracted. The second part light L42 will be directly projected to the condenser lens 413 to be refracted. Then the light above the cut-off line will be shaded, blocked, and shielded by the cut-off screen 414, so as to eventually form a low beam light spot. The cut-off screen 414 can be driven to rotate by electrifying the solenoid valve 416 to move the electromagnetic rod 4161. As a result, the cut-off line forming face will be shifted downward, such that the light emitted by the linear light source 411 will be projected below the focus area of the condenser lens 413, so as to form the high beam light spot; and rotating the cut-off screen 414 to restore and reposition to restore the low beam light spot by means of cutting off the power of the solenoid valve 416 to restore and reposition the electromagnetic rod 4161.

[0347] Further, the illumination method integrating high and low beams also comprises a step of:
shading the light above the light and shade cut-off line of the first part light L41 being reflected by the linear focus reflector 412 by the cut-off screen 414.

[0348] Further, according to the illumination method of the lighting system integrating high and low beams, the first part light L41 reflected by the first linear focus reflector 412 comprises the following portions:

reflecting part of the light L411 to the condenser lens 413 by the horizontal linear reflecting surfaces 412111;

reflecting part of the light L412 to the condenser lens 413 by the light spreading cambered surfaces 412112;

reflecting part of the light L413 through the mirror reflecting surfaces 4122111 to the horizontal linear reflecting surfaces 412111, converged on the linear focus F2, and then projected to the condenser lens 413;

reflecting part of the light L414 to the condenser lens 413 by the mirror reflecting surfaces 4122111; and

reflecting part of the light L415 to the condenser lens 413 by the collecting surfaces 4122121. The second part light L42 and part of the light L411-L414 are all within the scope of the subtended angle of the condenser lens 413, while part of the light L415 emerges out of the scope of the subtended angle of the condenser lens 413.

[0349] The excess part of light will be blocked and shaded by the cut-off screen 414 from emerging outward, so as to make a light and shade cut-off line for the low beam light spot.

[0350] It utilizes the function of arrangement of the linear focus reflector 412 and the cut-off screen 414 with the condenser lens 413, to increase the width of left and right of the low beam lamp from ten thousand cd to 18° each for the left and right sides, so as to satisfy the demand of wider and brighter sight. Besides, the light intensity of the central zone has been increased to more than fifty thousand cd, which extends the illumination distance of the central zone for the right-hand traffic. Meanwhile, its light and shade cut-off line is clear, which helps to avoid glare and dazzle for the opposite drivers and pedestrians.

[0351] In other words, the part of the light L411 of the first part light L41 emitted by the linear light source 411 is reflected by the horizontal linear reflecting surfaces 412111 to the condenser lens 413 to be refracted. The part of the light L412 of the first part light L41 emitted by the linear light source 411 is reflected by the light spreading cambered surfaces 412112 to the condenser lens 413 to be refracted. The part of the light L413 of the first part light L41 emitted from the linear light source 411 will be reflected to the horizontal linear reflecting surfaces 412111 by the mirror reflecting surfaces 4122111 to be converged on the linear focus F2. Then the light will hit the condenser lens 413 to be refracted. The part of the light L414 of the first part light L41 emitted by the linear light source 411 will be reflected by the mirror reflecting surfaces 4122111 to the condenser lens 413 to be refracted. The part of the light L415 of the first part light L41 emitted by the linear light source 411 will be reflected by the collecting surfaces 4122121 to the condenser lens 413 to be refracted. The second part light L42 emitted from the linear light source 411 will directly hit the condenser lens 413 to be refracted. Part of the light will be shaded and blocked by the cut-off screen 414 from being projected outward, so as to form the light and shade cut-off line for the low beam light spot. The cut-off screen 414 can be driven to rotate by electrifying the solenoid valve 416 to move the electromagnetic rod 4161. As a result, the cut-off line forming face will be shifted downward, such that the light will be projected below the focus area of the condenser lens 413, so as to form the high beam light spot. The cut-off screen 414 will rotate to restore and reposition to restore the low beam light spot by means of cutting off the power of the solenoid valve 416 to restore and reposition the electromagnetic rod 4161.

[0352] Referring to Figs. 60-68, the present invention further comprises a headlamp. The headlamp comprises at least a linear light source 411, at least a reflective device 470, and at least a condenser lens 413. When it also comprises at least a cut-off screen 414, it will be embodied as a low beam headlamp. When it further comprises a solenoid valve 416 for driving the cut-off screen 414 to conduct rotation relatively to the reflective device 470 rather than keep shading and blocking the light to form the light and shade cut-off line, the headlamp may be embodied as a high beam headlamp. The reflective device 470, at the linear focus F1, reflects at least part of the light emitted by the linear light source 411. At least part of the light of the linear light source 411 reflected by the reflective device 470 is converged on a linear focus F2. The cut-off screen 414 is mounted and arranged at the linear focus F2 for shading the light above the cut-off line. The first condenser lens 413 is mounted and arranged in front of the linear focus F2 to refract the light of the linear light source 411 through principle of lens, so as to eventually form a low beam lamp light spot for the low beam headlamp

[0353] Specifically speaking, the linear light source 411 is embodied as a plurality of LEDs 4111. The LEDs 4111 can be five-chip LED module of 1500Lm and 5700K color temperature arranged in the middle and two single-chip ceramic packaged LEDs 111 of 250Lm, warm white light, and 3000K color temperature respectively arranged in both the left and right, which hybridly utilizes white light and warm white light to lower the color temperature of the complete lamp, which enhances the penetrability of the light under foggy day and rainy day and makes the state of roads more clear. All the LEDs 4111 are arranged in a horizontal linear manner and the illumination direction of the LEDs 4111 is the same to the direction of the optic axis of the low beam headlamp and coincides with the focus F1 of the reflective device.

[0354] According to another alternative mode of the embodiment of the present invention, the linear light source 411 is a set horizontally and linearly aligned multicore LED modules, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source.

[0355] According to another alternative mode of the embodiment of the present invention, the linear light source 411 is a plurality sets of horizontally and linearly aligned single-chip LED modules.

[0356] According to another alternative mode of the embodiment of the present invention, the linear light source 411 is a plurality sets of horizontally and linearly aligned multicore LED modules, wherein the LEDs include combinations of white light and warm white light or white light, warm white light, and golden light, so as to lower the color temperature of the linear light source.

[0357] Referring to Figs. 61-63, the reflective device 470 is a light funnel linear focus reflection structure with a relatively small opening and the linear light source 411 utilizes the reflection surfaces inside of the reflective device 470 for reflection. Preferably, a reflecting layer is coated and provided on the inner surfaces of the reflective device 470, so as to further enhance the reflectivity and the reflection strength to the light of the linear light source 411.

[0358] Specifically speaking, the reflective device 470 comprises a reflection light funnel 471 and two reflection extension portions 472 that have same structure and are spacingly arranged. The reflection light funnel 471 forms, provides, and defines a cavity 4700 therein. The light of the linear light source 411 is projected into the internal of the reflection light funnel 471 to be reflected. Then the reflected light will be emitted from the opening. Each of the reflection extension portions 472 comprises a first section 4721 and a second section 4722. The first section 4721 of the reflection extension portion 472 extends outward from the two sides of another end of the reflection light funnel 471 along the illumination direction of the linear light source 411 and closes inward to form the second section 4722. In other words, a second angle α2 is created between the first section 4721 and the second section 4722 of the reflection extension portion 472 and a first angle α1 is created between the first section 4721 of the reflection extension portion 472 and the reflection light funnel 471.

[0359] The scope of the first angle α1 is 180°-270°, and preferably 225°. The scope of the second angle α2 is 0°-180°, which can be, for instance, 150°. An opening that opens outward can be formed between it and the reflection light funnel 471. The angle between the reflection light funnel 471 and the first section 4721 of the reflection extension portion 472 can be, for instance, 225°. In other words, two of the reflection extension portions 472 are respectively extended outward from the two sides of the reflection light funnel 471 for such as 45° and closed inward respectively for such as 30°, so as to form, for instance, 225° between the first section 4721 of the reflection extension portion 472 and the reflection light funnel 471 and form, for instance, 150° between the first section 4721 and the second section 4722 of the reflection extension portion 472.

[0360] In detail, the reflection light funnel 471 comprises a horizontal linear reflecting surface 4711 and a light spreading cambered surface 4712 respectively arranged on the upper surface and the lower surface of the internal thereof. The horizontal linear reflecting surfaces 4711 and the light spreading cambered surfaces 4712 are both utilized for reflecting the light of the first linear light source 411. The horizontal linear reflecting surface 4711 is close to the linear light source 411. The light spreading cambered surface 4712 is extended from the horizontal linear reflecting surfaces 4711 and away from the side of the linear light source 411. The reflection light funnel 471 comprises an ellipse line reflecting side 4713 and a non-ellipse line reflecting surface 4714 respectively arranged on the two sides in the internal thereof. The ellipse line reflecting surface 4713 and the non-ellipse line reflecting surface 4714 are both utilized for reflecting the light of the linear light source 411. The ellipse line reflecting surface is close to the side of the linear light source 411. The non-ellipse line reflecting surface 4714 is extended from the ellipse line reflecting surface 4713 and away from the side of the linear light source 411. In other words, the reflection light funnel 471 comprises a horizontal linear reflecting surface 4711 and a light spreading cambered surface 4712 respectively arranged on the upper surface and the lower surface of the internal thereof. The horizontal linear reflecting surface 4711 is formed by stretching mainly on the basis of ellipse lines and partially on the basis of non-ellipse lines. The light of the linear light source 411 is converged on the linear focus F2 by the horizontal linear reflecting surface 4711, so as to enhance the light intensity of the center. The light spreading cambered surface 4712 is mainly to shift part of the light of the linear light source 411 upward from the linear focus F2, so as to increase the light distribution to the ground illumination. The reflection light funnel 471 comprises an ellipse line reflecting surface 4713 and a non-ellipse line reflecting surface 4714 respectively arranged and extended along the length direction on the left side and the right side of the internal thereof. The function of the ellipse line reflecting surface 4713 and the non-ellipse line reflecting surface 4714 is to reflect and converge the light of the linear light source 411 on the linear focus F2.

[0361] Because the second section 4722 of the reflection extension portion 472 is bent inward, the inner surface of the second section 4722 of the reflection extension portion 472 will involve in the reflection of the light of the first linear light source 411. The inner surface of the second section 4722 of the reflection extension portion 472 is a plane that inclines inward for a certain angle. In other words, the reflection extension portion 472 comprises a reflection surface 47221, mainly formed by a plane inclining inward for a certain angle, for being a collecting surface, so as to reflect the light projected from the linear light source 411 to the condenser lens 413. Then the light will be refracted by the condenser lens 413 to the ground area of a wide angle. In addition, the light emitted by the linear light source 411 beyond the subtended angle of the condenser lens 413 can be reflected by the reflection surfaces 47221, so as to be converged again on the condenser lens 413 for being refracted to the illumination area of the left and right sides, such as a 40° illumination area and etc..

[0362] Referring to Fig. 61, for the low beam headlamp of the present invention, the shape of the cut-off line forming face of the cut-off screen 414 can be a 15° oblique line, 45° oblique line, 90° right angle or 0° horizontal line. The cut-off screen 414 comprises a horizontal member 414a and a vertical member 414b. An end of the horizontal member 414a and an end of the vertical member 414b are coincided and the horizontal member 414a and the vertical member 414b are arranged perpendicularly to each other, so as to make the cut-off screen 414 be arranged in a L shape approximately. The cut-off screen 414 comprises at least a rotating hole 4141, at least a moving slot 4142, at least a windowing groove 4143, and at least a jagged sheet 4144. The cut-off screen 414 is mounted on the reflective device 470 and arranged along the linear focus F2. The jagged sheet 4144 is provided on the cut-off line forming face. The solenoid valve 416 comprises an electromagnetic rod 4161 affixedly arranged thereon. The moving slot 4142 and the electromagnetic rod 4161 of the solenoid valve 416 are affixedly connected. The rotating hole 4141 is provided at the coinciding end of the horizontal member 414a and the vertical member 414b, in the manner that the cut-off screen 414 is able to rotate along the rotating hole 4141. Hence, when the solenoid valve 416 is driven to drive the electromagnetic rod 4161 to move, the solenoid valve 416 will be able to push the electromagnetic rod 4161 to push the cut-off screen 414 to move along the moving slot 4142. Meanwhile, the cut-off screen 414 will rotate along the rotating hole 4141, so as to allow the light that was shaded by the cut-off screen 414 pass through the cut-off screen 414 to reach the condenser lens to be refracted to eventually form the high beam light spot.

[0363] Referring to Figs. 59-60, the jagged sheet 4144 is in a triangle-like shape and the jagged sheet 4144 has a stretched zigzag structure arranged on the surface thereof for reducing the proportion of the blue light at the cut-off line as well as for modifying the light projected to the jagged sheet 4144 to prevent the reflected and diffused reflected light from being projected to the condenser lens 413, so as to make the light and shade cut-off line more clear.

[0364] Referring to Fig. 61, the windowing groove 4143 is arranged on the horizontal member 414a, so as to allow the light projected by the linear light source 411 to pass through the windowing groove 4143. The low beam lamp of the present invention further comprises an optical filter 415 affixedly arranged in the windowing groove 4143 of the cut-off screen 414. The part of the light passing through the cut-off screen 414 will then pass by the optical filter 415 arranged in the windowing groove 4143, so as to weaken the light and diffuse it to the condenser lens 413. Then the light will be refracted by the condenser lens 413 to the cut-off line to be refracted to the dark zone above the cut-off line to form a weak light zone (Zone γ) in order to enhance the light intensity of PI to P6 without enhancing the light intensity of P7, P8, B50L and HV testing point, so as to allow the pedestrian of the opposite side to clearly see the passing of the vehicle in the front. The jagged sheet 4144 of the cut-off line forming face can shade the light of large incident angle from the condenser lens 413, so as to reduce the proportion of blue light at the cut-off line and to eliminate the blue light runoff at the cut-off line.

[0365] According to the above preferred embodiment of the present invention, the optical filter 415 may be made of opaque material, semi-transparent material, diffused material, white material, and etc.. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, material of the optical filter of the present invention shall not be limited thereby.

[0366] According to the above embodiment of the present invention, the shape of the windowing groove 4143 is rectangle. The shape and size of the optical filter 415 is the same and matches to the windowing groove 4143, so as to allow the optical filter 415 to be affixed in the windowing groove 4143. According to an alternative mode of the present invention, the shape of the windowing groove 4143 may also be embodied as square shape, circular shape, oval shape, and etc., or the shapes of multiple squares, circles, ovals, combinations thereof, and etc.. The shape of the cut-off screen 414 may also be embodied as square shape, circular shape, oval shape, and etc., or the shapes of multiple squares, circles, ovals, combinations thereof, and etc., or shapes of trademarks and words. Namely, the shape of the optical filter 415 is not limited by the shape and quantity of the windowing groove 4143.

[0367] Referring to Fig. 64, according to the present embodiment, the condenser lens 413 is an optical lens for eliminating blue light runoff, which comprises an input optical surface 4133, an output upper optical surface 4131, and an output lower optical surface 4132. More preferably, the input optical surface 4133 of the condenser lens 413 is a plane or non-plane optical surface, the output upper optical surface 4131 is arranged and positioned above the central horizontal axis and is a condensation surface, and the output lower optical surface 4132 is arranged and positioned below the central horizontal axis and is an irregular surface and non-rotating surface.

[0368] Referring to Fig. 65, the central section plane of the output lower optical surface 4132 of the condenser lens 413 can be divided into several optical curves 41321, 41322, 41323......4132*. The parameters of the present invention is as follows: 41321 indicates the light of several optical surfaces laterally will lean slightly downward between 0° to 0.05°, 41322 indicates the light of several optical surfaces laterally will lean slightly downward between 0.05° to 0.1°, 41323 indicates the light of several optical surfaces laterally will lean slightly downward between 0.1° to 0.15°, and 4132* indicates the light of several optical surfaces laterally will lean slightly downward between 0.05 times * degree to 0.05 times * degree. Nevertheless, the parameters may vary.

[0369] It should be noted that the condenser lens 413 is an optical lens to eliminate blue light runoff and that the output lower optical surface 4132 is adjusted so as to have the blue light of the output lower optical surface 4132 to be parallel to or lower than the yellow light of the output upper optical surface 4131, such that the yellow light of the output upper optical surface 4131 will completely cover the blue light of the output lower optical surface 4132 and the yellow light of the output lower optical surface 4132 will also completely cover the blue light of the output upper optical surface 4131, which eventually forms a light spot without blue light runoff at the cut-off line.

[0370] In other words, according to the present embodiment, the output lower optical surface 4132 is adjusted so as to have the blue light of the output lower optical surface 4132 to be parallel to or lower than the yellow light of the output upper optical surface 4131, such that the yellow light of the output upper optical surface 4131 will completely cover the blue light of the output lower optical surface 4132 and the yellow light of the output lower optical surface 4132 will also completely cover the blue light of the output upper optical surface 4131, which eventually forms a light spot without blue light runoff at the cut-off line.

[0371] It should be noted that for an optical lens for eliminating the blue light runoff, the light source is a white light LED light source, which produces and mixed white light through phosphor powder stimulated by blue light. Therefore, the light is mainly formed by yellow light and blue light. The refractive indexes of light of different wavelengths are different for the same medium, wherein the longer the wavelength, the smaller the refractive index will be, while the shorter the wavelength, the larger the refractive index will be. Therefore, after the lights L4101...L4102...L4103 that pass through F1 have passed through the input optical surface 4133, they will be refracted into blue light portions L4101B...L4102B...L4103B and yellow light portions L4101Y...L4102Y...L4103Y. The bigger the incident angle of the blue light, the bigger the deviation angle thereof will be. Then the lights will be refracted through the output upper optical surfaces 4131 and divided into downward inclined portions L4101B'...L4102B'...L4103B' and parallel lights L4101Y'...L4102Y'...L4103Y'. After the lights L4201...L4202...L4203 that pass through F1 have passed through the input optical surfaces 4133, they will be refracted into blue light portions L4201B...L4202B...L4203B and yellow light portions L4201Y...L4202Y...L4203Y. The bigger the incident angle of the yellow light, the bigger the deviation angle thereof will be. Then the lights will be refracted through the output optical surfaces 4132 and divided into parallel lights L4201B'...L4202B'...L4203B and downward inclined portions .L4201Y'...L4202Y'...L4203Y'. The parallel lights L4101Y'...L4102Y'...L4103Y' and the parallel lights L4201B'...L4202B'...L4203B' are mixed to form a light spot without blue light runoff, while the downward inclined portions L4101B'..L4102B'...L4103B' and the downward inclined portions L4201Y'...L4202Y'...L4203Y' are mixed to form a light spot without blue light runoff as well, so as to eventually eliminate the blue light runoff from the light spot at the cut-off line.

[0372] As an option, either one or both of the output lower optical surfaces 4132 or the output upper optical surfaces 4131 may be a modified curved surface(s). Alternatively, the input optical surface 4133 can be a modified curved surface.

[0373] It should be noted that because the opening of the reflective device 470 is relatively small and the reflecting surfaces disposed internally is deep, the reflective device 470 is arranged to include two symmetrical structures, the reflection unit 470a and the reflection unit 470b, in order for coating the reflection layer for the reflecting surfaces. The reflection unit 470a and the reflection unit 470b are respectively mounted and arranged in the top and bottom sides of the linear light source 411 so as to reflect the light of the linear light source 411. This arrangement is able to reduce the part types of the product and therefore lower the costs of the low beam headlamp.

[0374] Similarly, the reflective device 470 may also be longitudinally divided into two symmetrical portions that are replaceable to each other, which is helpful for coating reflecting layer on the reflecting surfaces in the reflective device 470. Besides, it can also reduce the part types of the product and therefore enhance productivity. Besides, the material of the reflection layer of the reflecting surfaces of the reflective device 470 can be selected, based on actual needs, from the materials such as metal coating, alloy coating, compound coating, and etc.. All implementations that utilize the same or similar technology to the present invention, solve the same or similar technical issue of the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0375] In summary, because the opening of the reflective device 470 is relatively small, the light of the linear light source 411 projected from the opening will directly be converged on the condenser lens 413 to be refracted to the ground. Therefore, it can fully collect the light projected from the linear light source 411 in the 360° scope, which means relatively high light collection. As a result, it is able to not only increase the brightness of the low beam headlamp, but also decrease the power consumption of the entire lamp. Besides, it can distribute the light projected from the linear source 411 for linear focuses, so as to concentrate the beam on the horizontal axis, which distributes more light for the distant place of the vehicle and makes the illumination vision farther, wider, and brighter.

[0376] Referring to Figs. 66-68, according to an alternative mode of the present invention, the structure of the reflective device 480 is as illustrated in the figures. Differences between the reflective device 480 and the above reflective device 470 include the surfaces of the two inner sides of the reflection light funnel 481 are mirror surfaces 4813 that are based on planes to mirror the light of the linear light source 421 to the horizontal linear reflecting surfaces 4811 or the mirror surfaces 4813 of the opposite side, so as to eventually reflect the light to the linear focus F2.

[0377] Hence, referring to Figs. 69-70, the operating principles of the headlamp of the present invention include:

[0378] Part of the light emitted by the linear light source 411 will be reflected one or more times by the reflective device 470(480) and then hit the cut-off screen 414. The cut-off screen 414 will shade the portion of the light above the cut-off line and then weaken and diffuse it through the optical filter 415, while the rest of the light will reach the condenser lens 413 to be refracted, so as to form and produce the low beam light spot.

[0379] Another part of the light emitted by the linear light source 411 will directly hit the cut-off screen 414. The cut-off screen 414 will shade the portion of the light above the cut-off line and then weaken and diffuse it through the optical filter 415, while the rest of the light will reach the condenser lens 413 to be refracted, so as to form and produce the low beam light spot.

[0380] Then it drives the solenoid valve 416. Due to the drive of the solenoid valve 416, the electromagnetic rod 4161 will bring the cut-off screen 414 to rotate, so as to allow the light that was shaded by the cut-off screen 414 as mentioned above to fully reach the condenser lens 413 to be refracted, so as to form the high beam light spot. Hence, it may quickly implement the switching of the high beam effect and the low beam effect by driving the solenoid valve 416 to restore and reposition to switch between the high beam light spot and the low beam light spot again.

[0381] Referring to Fig. 66, the headlamp further comprises an outer cover 430 and a heat dissipation body 440. The outer cover 430 comprises a first portion 431 and a second portion 432. The first portion 431 and the second portion 432 form an accommodation cavity 4300 for accommodating the high beam headlamp. The second portion 432 acts as the back end. The heat dissipation body 440 is affixed and disposed on the second portion 432. The first portion 431 acts as the front end and comprises an opening 4310. The opening 4310 is utilized for placing the condenser lens 413 and for the light of the linear light source 411 to pass through. The heat dissipation body 440 is preferably made of metal, so as to have high heat dissipation quality.

[0382] The headlamp further comprises an outer lens 450, affixedly connected with the front end of the outer cover 430, such that the headlamp can be waterproof and dustproof. The linear light source 411 of the headlamp can be directly affixed on the heat dissipation body 440. Because the heat transmission speed of the heat dissipation body 440 is fast, the arrangement of the heat dissipation body 440 can avoid service life decrease of the linear light source 411 due to rapid temperature increase or failure of timely heat dissipation.

[0383] Moreover, the headlamp of the present invention further comprises a front position lamp optical lens 492 and a front position lamp light source unit 491, wherein the front position lamp optical lens 492 and the front position lamp light source unit 491 are sequentially affixed between the outer lens 450 and the outer cover 430, so as to further enhance the illuminating effect of the lighting system integrating high and low beams.

[0384] According to the embodiment of the present invention, the outer lens 450 is affixedly connected with the front end of the outer cover 430 through sealant, so as to achieve a waterproof and dustproof effect for the linear light source 411, the reflective device 470(480), the cut-off screen 414, the solenoid valve 416, and the optical filter 415. Nevertheless, the embodiment and practice of the present invention shall be limited thereby. Person skilled in the art is able to utilize any means to affix the outer lens 450 on the front end of the outer cover 430 based on the above disclosed notions. All implementations that utilize the same similar technology to the present invention, solve the same or similar technical issue the present invention, and achieve the same or similar effect to the present invention shall be in the scope of the present invention. Namely, the embodiment and practice of the present invention shall not be limited thereby.

[0385] Preferably, the headlamp further comprises a metal heat dissipation board 460. The linear light source 411 is directly affixed on the metal heat dissipation board 460 through welding, soldering, screwing or other means. Preferably, the heat conduction surface of the LED of the linear light source 411 is directly mounted on the metal heat dissipation board 460 having a large size. The surface area of the metal heat dissipation board 460 is big, which benefits to heat dissipation. The linear light source 411 affixed and welded on the metal heat dissipation board 460 is then affixedly connected with the heat dissipation body 440. Because the contacted area of the metal heat dissipation board 460 and the heat dissipation body 440 is big, it can therefore further enhance the heat dissipation of the linear light source 411, so as to extend the service life of the headlamp.

[0386] Referring to Figs. 71-73, the present invention further provides an illumination method for headlamp, comprising the following steps:

emitting light L with the linear light source 411;

reflecting the light L emitted by the linear light source 411 with the reflective device 470(480);

utilizing the condenser lens 413 to refract the light L emitted by the linear light source 411, wherein the light L emitted by the linear light source 411 comprises a first part light L41 and a second part light L42. The first part light L41 will be reflected by the reflective device 470 (480) to the condenser lens 413 to be refracted. The second part light L42 will be directly projected to the condenser lens 413 to be refracted. Then the light above the cut-off line will be shaded, blocked, and shielded by the cut-off screen 414, so as to eventually form a low beam light spot; and

driving the cut-off screen 414 to rotate by electrifying the solenoid valve 416 to move the electromagnetic rod 4161. As a result, the cut-off line forming face will be shifted downward, such that the light will be projected below the focus area of the condenser lens 413, so as to form the high beam light spot. The cut-off screen 414 will rotate to restore and reposition to restore the low beam light spot by means of cutting off the power of the solenoid valve 416 to restore and reposition the electromagnetic rod 4161.

[0387] Further, the illumination method of the headlamp comprises a step of:
shading the light above the light and shade cut-off line of the first part light L41 being reflected by the reflective device 470(480) by the cut-off screen 414.

[0388] Further, according to the illumination method of the headlamp, the first part light L41 reflected by the reflective device 470(480) comprises the following portions:

reflecting the part of the light L411 to the condenser lens 413 by the horizontal linear reflecting surfaces 4711;

reflecting the part of the light L412 to the condenser lens 413 by the light spreading cambered surfaces 4712;

reflecting the part of the light L413 through the mirror reflecting surfaces 4713 to the horizontal linear reflecting surfaces 4711, converged on the linear focus F2, and then projected to the condenser lens 413;

reflecting the part of the light L414 to the condenser lens 413 by the mirror reflecting surfaces 4713; and

reflecting the part of the light L415 to the condenser lens 413 by the collecting surfaces 47221. Besides, the second part light L42 and part of the light L411-L414 are all within the scope of the subtended angle of the condenser lens 413, while part of the light L415 emerges out of the scope of the subtended angle of the condenser lens 413.

[0389] The excess part of light will be blocked and shaded by the cut-off screen 414 from emerging outward, so as to make a light and shade cut-off line for the low beam light spot.

[0390] It utilizes the function of arrangement of the reflective device 470(480) and the cut-off screen 414 with the condenser lens 413, to increase the width of left and right of the low beam lamp from ten thousand cd to 18° each for the left and right sides, so as to satisfy the demand of wider and brighter sight. Besides, the light intensity of the central zone has been increased to more than fifty thousand cd, which extends the illumination distance of the central zone for the right-hand traffic. Meanwhile, its light and shade cut-off line is clear, which helps to avoid glare and dazzle for the opposite drivers and pedestrians.

[0391] In other words, the part of the light L411 of the first part light L41 emitted by the linear light source 411 is reflected by the horizontal linear reflecting surfaces 4711 to the condenser lens 413 to be refracted. The part of the light L412 of the first part light L41 emitted by the linear light source 411 is reflected by the light spreading cambered surfaces 4712 to the condenser lens 413 to be refracted. The part of the light L413 of the first part light L41 emitted from the linear light source 411 will be reflected to the horizontal linear reflecting surfaces 4711 by the mirror reflecting surfaces 4713 to be converged on the linear focus F2. Then the light will hit the condenser lens 413 to be refracted. The part of the light L414 of the first part light L41 emitted by the linear light source 411 will be reflected by the mirror reflecting surfaces 4713 to the condenser lens 413 to be refracted. The part of the light L415 of the first part light L41 emitted by the linear light source 411 will be reflected by the collecting surfaces 47221 to the condenser lens 413 to be refracted. The second part light L42 emitted from the linear light source 411 will directly hit the condenser lens 413 to be refracted. Part of the light will be shaded and blocked by the cut-off screen 414 from being projected outward, so as to form the light and shade cut-off line for the low beam light spot. The cut-off screen 414 can be driven to rotate by electrifying the solenoid valve 416 to move the electromagnetic rod 4161. As a result, the cut-off line forming face will be shifted downward, such that the light will be projected below the focus area of the condenser lens 413, so as to form the high beam light spot. The cut-off screen 414 will rotate to restore and reposition to restore the low beam light spot by means of cutting off the power of the solenoid valve 416 to restore and reposition the electromagnetic rod 4161.
