Description

TECHNICAL FIELD

[0001] The present disclosure relates to a dual reflector adjusting module for an LED lamp and a lighting lamp implement using of the same, in particular to, a dual reflector adjusting module for an LED lamp and a lighting lamp implement using of the same capable of implementing an optimum uniformity factor by forming a light distribution curve suitable for the object to be projected, obtaining four each different light distribution curves through four light transmitting holes in one light projector, and making a convenient application by overcoming a limit of vertical illuminance of 10 lux through a size adjustment and direction of a lighting area in any site condition by controlling an angle of the front and rear reflectors according to the standards of the Light Pollution Prevention Act.

BACKGROUND ART

[0002] The known LED asymmetric lighting method executes lighting by allowing light generated from an LED to be emitted through an asymmetric reflector facing each other. In this case, lighting is provided only in the area of a limited size by the inherent radius of curvature of a reflector. Accordingly, there is an inconvenience such that it is impossible to adjust a lighting direction and a lighting area to be large or small tailored for the installation situation of LED lighting equipment.

[0003] As a background technology of the present disclosure, as Korean Patent No. 10-2030931 entitled 'Glare-Free Asymmetry Floodlighting Reflector and Flood Light Using Same' has been proposed. This provides an asymmetry floodlighting reflector which has an asymmetrical reflection structure to eliminate glare during illumination at night and increases illuminance and luminance for a wide floodlighting area, and a flood light using the same. Herein, the asymmetry floodlighting reflector comprises a first reflective curved portion and a second reflective curved portion asymmetrical to a side facing the first reflective curved portion. However, in the background technology, since the first and second reflective curved portions are fixedly installed, it is difficult to form a light distribution curve suitable for the object to be projected, and an angle cannot be controlled, so there is a limitation in applying it to various site conditions.

DESCRIPTION OF EMBODIMENTS

[0017] Hereinafter, the present disclosure is described in detail with reference to exemplary embodiments illustrated in the accompanying drawings, but the proposed exemplary embodiments are exemplified for a clear understanding of the present disclosure and the present disclosure is not limited thereto.

[0018] The dual reflector adjusting module 10 for an LED lamp according to an embodiment of the present disclosure is provided with a reflector housing 12 having a light transmitting hole 12a opened to one side as shown in FIGS. 1 to 5. The reflector housing 12 includes a housing floor plate 121 formed in a rectangular strip shape having an opening 121a for arranging an LED in communication with a light transmitting hole 12a, a housing wall 122 stood at a predetermined height along a housing floor plate 121, one or more first hinge grooves 123 formed to hinge combine a rear reflector 14 to a lower surface of a housing floor plate 121, one or more second hinge grooves 124 formed at a certain distance from the first hinge groove 123 to hinge combine a front reflector 16 to a lower surface of a housing floor plate (121); and a servomotor mount 125 on a housing floor plate 121 side to install a first servomotor 18 and a second servomotor 20.

[0019] In this embodiment, the first hinge groove 123 is formed in two places with a constant shaft distance h1, and the second hinge groove 124 is formed in two places with a shaft distance h2 different from the shaft distance h1. However, the present disclosure is not limited to such places, and may be formed at places more than that places or at one place as shown in FIGS. 7a and 7b.

[0020] The rear reflector 14 hinge combined to be rotatable to one side of the reflector housing 12 is provided. The rear reflector 14 is installed by being hinge combined with the first hinge groove 123 formed on the lower surface of the housing floor plate 121. Accordingly, the rear reflector 14 is rotatable with the first hinge groove 123 as a first rotation shaft X1. The radius of curvature R1 of the rear reflector 14 is formed smaller than the radius of curvature R2 of the front reflector 16 and is installed in a mutually asymmetrical shape. When installed in this way, constructive interference occurs to increase the illuminance and brightness of the corresponding lighting area. The rear reflector 14 and the front reflector 16 may have a radius of curvature on either side or both may be installed with a flat reflective surface without curvature.

[0021] In this embodiment, the rear reflector 14 is provided with three in number having reflection angles of 30°, 48°, and 60° of which any one of them is selected and is installed so that the rotation angle may be adjusted by selecting any one place of the first hinge grooves 123 of two places. The reflection angle of the rear reflector 14 is not limited to this embodiment.

[0022] The front reflector 16 hinge combined to be rotatable to the other side of the reflector housing 12 facing the rear reflector 14 is provided. The front reflector 16 is installed by being hinge combined with the second hinge groove 124 formed on the lower surface of the housing floor plate 121. Accordingly, the front reflector 16 is rotatable with the second hinge groove 124 as the second rotation shaft X2.

[0023] In this embodiment, the front reflector 16 is provided with three in number having reflection angles of 30°, 48°, and 60° of which any one of them is selected and is installed so that the rotation angle may be adjusted by selecting any one of the second hinge grooves 123 of two places. The reflection angle of the front reflector 16 is not limited to this embodiment.

[0024] The first servomotor 18 and the second servomotor 20 are installed on parallel on the reflector housing 12 side. In this embodiment, the first servomotor 18 and the second servomotor 20 are installed on parallel on a servomotor mount 125 installed on the housing floor plate 121 side of the reflector housing 12.

[0025] A first arm 22 for rotationally driving the rear reflector 14 is connected to the rotation shaft of the first servomotor 18 via the rear reflector drive link 24. A plurality of rear reflector drive link connection holes 22a formed at regular intervals are formed to increase or decrease the rotation angle of the rear reflector 14 in the first arm 22. One end of the rear reflector drive link 24 is hinge connected by being inserted into any one of the plurality of rear reflector drive link connection holes 22a. Accordingly, the rear reflector drive link 24 is hinge connected by selecting any one of the plurality of rear reflector drive link connection holes 22a, thereby controlling the adjustment of the rotation angle of the rear reflector 14 in various ways.

[0026] The rear reflector drive link 24 has one end connected to the first arm 22 and the other end connected to the rear reflector 14. The rear reflector drive link 24 is composed of a long wire rod, and it is preferable to have a bent stepped portion 24a formed by bending the portion twice at regular intervals in the longest straight section to prevent buckling during operation and reinforce flexural rigidity. In the case of configuring the rear reflector drive link 24 with a long wire rod, it is advantageous to manufacture the lighting lamp implement 100 as shown in FIG. 8a by arranging the dual reflector adjusting module 10 for an LED lamp on parallel in close proximity as shown in FIG. 8b.

[0027] A second arm 26 for rotationally driving the front reflector 16 is connected to the rotation shaft of the second servomotor 20 via the front reflector drive link 28. A plurality of front reflector drive link connection holes 26a formed at regular intervals are formed to increase or decrease the rotation angle of the front reflector 16 in the second arm 26. Accordingly, the front reflector drive link 28 is hinge connected by selecting any one of the plurality of front reflector drive link connection holes 26a, thereby controlling the adjustment of the rotation angle of the front reflector 16 in various ways.

[0028] The front reflector drive link 28 has one end connected to the second arm 26 and the other end connected to the front reflector 16. In this embodiment, the front reflector drive link 28 has one end hinge connected to one of the plurality of front reflector drive link connection holes 26a of the second arm 26, and the other end hinge connected to a connecting piece 162 protruded on the rear surface of the front reflector 16.

[0029] The servomotor mount 125 has a heat dissipation opening 125a that is opened downward for heat treatment when the first servomotor 18 and the second servomotor 20 are operated. Accordingly, the lifespan of the first servomotor 18 and the second servomotor 20 is improved.

[0030] Unexplained reference numeral' 129' denotes 'a reinforcement bulkhead.'

[0031] In the dual reflector adjusting module 10 for an LED lamp configured as described above, the rear reflector 14 is rotated around the first hinge shaft X1 of the reflector housing 12 to adjust an angle via the rear reflector drive link 24 according to the rotational drive direction of the first servomotor 18 as shown in FIG. 3.

[0032] In addition, the front reflector 16 is rotated around the second hinge shaft X2 of the reflector housing 12 to adjust an angle via the front reflector drive link 28 according to the rotational drive direction of the second servomotor 20.

[0033] In the dual reflector adjusting module 10 for an LED lamp configured as described above, an LED element 50 is installed on the floor surface of the reflector housing 12 as shown in FIG. 8b, and a plurality of them are arranged on parallel, and are used as an LED lighting lamp implement 100 as shown in FIG. 8a. By adjusting the light distribution angle of the rear reflector 14 and the front reflector 16, an optimum uniformity factor may be implemented by forming a light distribution curve suitable for the object to be projected as illustrated in FIGS. 9a to 9f. In other words, it may be understood that a light distribution is made farther and wider when the front reflector 16 is varied on one side by 10 degrees as shown in FIG. 9b than when the front reflector 16 is varied on one side by 5 degrees as shown in FIG. 9a. In addition, it can be understood that a smaller light distribution is made when the rear reflector 14 is varied on a boundside by 10 degrees as shown in FIG. 9d than when the rear reflector 14 is varied on a boundside by 5 degrees as shown in FIG. 9c. In addition, it may be understood that a lighting is made farther when the front reflector 16 and the rear reflector 14 are varied on both sides by 5 degrees as shown in FIG. 9e than when the front reflector 16 and the rear reflector 14 are varied on both sides by 10 degrees as shown in FIG. 9f.

[0034] In addition, as shown in FIGS. 8a and 8b, when four dual reflector adjusting modules 10 for an LED lamp are applied to one lighting lamp implement 100, four each different light distribution curves may be obtained through four light transmitting holes. In addition, in the dual reflector adjusting module 10 for an LED lamp, the reflective surfaces of the rear reflector 14 and the front reflector 16 are installed asymmetrically, so there is an advantage in that it is possible to adjust a lighting direction and a size of a lighting area along with the glare-free lighting. Moreover, there is an advantage in that a convenient application may be made by overcoming a limit of vertical illuminance of 10 lux in any site condition by controlling two angles of the front reflector 16 and the rear reflector 14 according to the standards of the Light Pollution Prevention Act.

[0035] Reference numeral '90' denotes 'a front cover,' reference numeral '70' denotes 'a rear cover,' and reference numeral '80' denotes 'a lighting lamp implement hinge bracket.'

[0036] From the foregoing, the present disclosure has been described in detail by way of preferable examples. In addition, it will be appreciated by a person having ordinary skill in the pertinent technical field that various modifications and variations may be made without departing from the scope and technical spirit of the present disclosure with referenced to the preferable examples. However, the scope of the present disclosure is not limited by such modifications and variations, but should be interpreted by the appended claims.
