DETAILED DESCRIPTION

[0017] Further description will be given below to the advantages of the present invention with reference to the accompanying drawings and the preferred embodiments.

[0018] FIGS. 1 to 7 illustrate two preferred embodiments of the LED light source module provided by the present invention. The LED light source module comprises a light source plate 10, an integrated lens assembly 20, magnetic elements 30, and a power driving module 40. The light source plate 10 has a first surface and a second surface which are opposite to each other; a plurality of LED light sources 11 are attached to the first surface; the second surface faces a base (not shown) assembled on a mounting base; the power driving module 40 is electrically connected with the light source plate 10; and the integrated lens assembly 20 is fixed with the light source plate 10. In the present invention, the integrated lens assembly 20 and the light source plate 10 are fixed by a detachable connection mechanism, and the light source plate 10 is fastened through a plurality of fasteners or hooks disposed on the integrated lens assembly 20, so that complete assembly can be achieved. Of course, the present invention may still adopt other assembly methods, for instance, an undetachable connection mechanism such as gluing and welding, to realize the fixing of the integrated lens assembly 20 with the light source plate 10; in this way, no matter detachable connection mechanism or undetachable connection mechanism is adopted, the technical proposals shall all fall within the scope of protection of the present invention as long as the fixing effect of complete assembly of the integrated lens assembly 20 with the light source plate 10 is achieved and the luminous effect of the entire LED light source module is not disadvantageously affected.

[0019] Preferably, in the present invention, the integrated lens assembly 20 covers the outside of the first surface of the light source plate 10 and is provided with a plurality of lens units (e.g., hemispherical lenses 24) which respectively cover the outside of LED light sources 11; the integrated lens assembly 20 is provided with an accommodating space 25; and the power driving module 40 is accommodated within the accommodating space 25. In general, the integrated lens assembly 20 is made from an insulating material, preferably one of polycarbonate (PC), Acrylic or polymethyl methacrylate (PMMA). The three kinds of materials have the advantages of light weight, low cost and high transmittance and are relatively ideal materials taken as light guide components. As the power driving module 40 is accommodated into the accommodating space 25, the power driving module 40 can be insulated from the outside space through the integrated lens assembly 20, and the integrated lens assembly 20 is taken as a protecting cover and configured to protect the power driving module 40. In the present invention, the integrated lens assembly 20 receives emergent light of the light source plate 10. By adoption of the LED light sources 11 and the hemispherical lenses 24 which are arranged in one-to-one correspondence, the emergent light is refracted by the hemispherical lenses 24 and emitted to form scattered luminous spots, so that the function of lighting can be achieved.

[0020] In the two preferred embodiments, the integrated lens assembly 20 is equipped with a lens setting area provided with the plurality of hemispherical lenses 24 and a power supply accommodating area provided with the accommodating space 25 and configured to accommodate the power driving module 40; the lens setting area is disposed at the first height of the integrated lens assembly 20; and the power supply accommodating area is formed with being projected upwards from the first height, and a top surface of the power supply accommodating area is disposed at the second height. Due to the lens setting area and the power supply accommodating area with different heights, the integrated lens assembly 20 is L-shaped as a whole, and the power supply accommodating area higher than the lens setting area provides convenience to form the accommodating space 25 to accommodate the power driving module 40. Preferably, corresponding to the integrated lens assembly 20, the light source plate 10 is provided with a light source setting area provided with the plurality of LED light sources and a power supply area configured to mount the power driving module 40. The lens setting area covers the light source setting area, and the power supply area and the power supply accommodating area accommodate the power driving module 40 together. In the first preferred embodiment, the power supply accommodating area is disposed on one side of the lens setting area, and correspondingly the power supply area is disposed on one side of the light source setting area. In the second preferred embodiment, the power supply accommodating area is disposed in the middle part of the lens setting area, and correspondingly the power supply area is disposed in the middle part of the light source setting area. In the two optional preferred embodiments, both the two positions do not affect the luminous effect of the lamp, and the insulating effect of the power driving module 40 is also pretty good.

[0021] In the two preferred embodiments, a plurality of magnetic elements 30 and/or mechanical connecting elements (not shown, for example screws, in which case the integrated lens assembly 20 and the light source plate 10 are correspondingly provided with screw holes (not shown in the figure)) run through the integrated lens assembly 20 and the light source plate 10, and are adsorbed and/or assembled onto the base. Preferably, the plurality of magnetic elements 30 and/or mechanical connecting elements are concentrically spaced on a central portion and/or a body portion and/or an edge portion of the integrated lens assembly 20; and the light source plate 10 is correspondingly provided with through holes 12 with a shape matching with the magnetic elements 30 and/or the mechanical connecting elements to run therethrough and thus be fixed. In the first preferred embodiment, two magnetic elements 30 are respectively disposed at the central portion of the lens setting area and the central portion of the junction between the lens setting area and the power supply accommodating area; and the two magnetic elements 30 respectively fix the lens setting area and the power supply accommodating area. In the second preferred embodiment, three magnetic elements 30 are approximately distributed in a triangle, and the fixing effect can become better by utilization of the stability of the triangle.

[0022] The integrated lens assembly 20 includes a plurality of accommodating portions 21. The accommodating portions 21 are extended towards the light source plate 10 from the integrated lens assembly 20. Correspondingly, the light source plate 10 is provided with a plurality of through holes 12. The through holes 12 and the accommodating portions 21 are arranged correspondingly and have shapes matching each other, namely the accommodating portions 21 and the through holes 12 are in the same number; the accommodating portion 21 can just run through the through hole 12; and an outer wall of the accommodating portion 21 and an inner wall of the through hole 12 generate frictional contact therebetween. One magnetic element 30 is fixed in each accommodating portion 21; and meanwhile, the base of the lamp can adsorb the magnetic elements 30 disposed in the accommodating portions 21, and the accommodating portion 21 is attracted to the magnetic base as well. In this way, the integrated lens assembly 20 and the light source plate 10 are fixed on the magnetic base. In the present invention, the fixing effect of the LED light sources and the lamp can be achieved simply by adoption of the structure of the accommodating portions 21 and the through holes 12 provided on two components of the LED light source module, namely the light source plate 10 and the integrated lens assembly 20, with the magnetic elements 30 being inserted into the accommodating portions 21, and by utilization of magnetic attraction between the magnetic elements 30 and the magnetic base without additional assembling tools (e.g., screws and a screw driver), so that the assembly process can become more convenient. Meanwhile, the light source plate 10 and the magnetic base of the lamp are not isolated from each other by other component(s), and the thermal conductivity of general magnetic materials is also good, so that the thermal radiating effect of the entire lamp is relatively good. As shown in FIGS. 2 and 4, as the accommodating portion 21 includes a fixed end fixed onto the integrated lens assembly 20 and a free end 22 which is extended outward, and both the fixed end and the free end 22 of the accommodating portion are in structures provided with openings, the accommodating portion 21 is of an annular accommodating section, so that the magnetic elements 30 and the magnetic base of the lamp can be attached together, and hence the fixing effect of the LED light sources can be enhanced. As shown in FIGS. 1 and 3, a plurality of fastening stands 23, the height of which is gradually increased from the fixed end to the free end 22, are spaced on an inner wall of each accommodating portion 21; a cut-off end of the fastening stand 23 is higher than an initial end; by adoption of this configuration, a sliding chute guiding the magnetic element 30 to be embedded into the accommodating portion 21 can be formed at the initial end, so that the magnetic element 30 can more conveniently enter the accommodating portion 21; and when the magnetic element 30 slides to the cut-off end, the magnetic element 30 can be restricted at the free end 22 of the accommodating portion 21 by a higher lug boss at the cut-off end, so that the magnetic element 30 cannot be disengaged from the accommodating portion 21 to damage the LED light source in the operation of the lamp. As shown in FIG. 2, an extension end of the accommodating portion 21 may be formed with a plurality of cambered elastic clamping parts; a gap is formed between two adjacent clamping parts and is extended from the cut-off end of the fastening stand 23 to the free end 22 of the accommodating portion 21; and these clamping parts can clamp the magnetic element 30 and cooperate with the fastening stand 23 to fix the magnetic element 30. The magnetic element 30 can be more conveniently detached by adoption of the plurality of cambered elastic clamping parts provided with gaps interposed there between to clamp the magnetic element 30.

[0023] In the present invention, the integrated lens assembly 20 and the light source plate 10 are fixed by a detachable connection mechanism, so that assembly, disassembly and maintenance can become more convenient.

[0024] In various detachable connection fixing means, the first optional fixing means is illustrated in FIGS. 1 to 7, the shape of the integrated lens assembly 20 matches with the shape of the light source plate 10; the integrated lens assembly may be a light transmitting component of a plate shape; a plurality of elastic fasteners 26 extended in the direction towards the light source plate are spaced at the edge of the integrated lens assembly and configured to fasten the light source plate 10; the elastic fasteners 26 may be provided at the encircling part which is entirely extended in the same direction; and by adoption of the encircling part, the integrated lens assembly 20 encircles the entire light source plate 10, has the function of electric shock isolation, and meanwhile protects the light source plate 10. In the first preferred embodiment, the elastic fasteners 26 on an encircling part are provided along the encircling part for encircling the lens setting area and the power supply area.

[0025] In the second optional fixing means, the integrated lens assembly 20 is provided with a plurality of pairs of elastic jaws 27 which are extended towards the light source plate 10; the light source plate 10 is provided with clamping holes 13 which are arranged corresponding to the elastic jaws 27; and the elastic jaws 27 run through the clamping holes 13 and clamp the light source plate 10. In the second preferred embodiment, four pair of elastic jaws 27 are adopted, and the elastic jaws 27 are disposed on the lens setting area of the integrated lens assembly 20 to approximately form a square.

[0026] The fixing means of adopting the mechanical connecting elements such as the elastic jaws 27 and the elastic fasteners 26 is an exemplary assembly method in consideration of both convenience and reliability. It should be conceived by those skilled in the art that the integrated lens assembly 20 and the light source plate 10 can also be fixed by various other common fixing means, for instance, fixing via a U-shaped clamp plate; the present invention only exemplifies two preferred fixing means; and the fixing of the integrated lens assembly 20 and the light source plate 10 by other fixing means shall obviously fall within the scope of protection of the present invention.

[0027] As shown in FIGS. 1 and 3, an adapter plate 41 is disposed between the power driving module 40 and the light source plate 10. By adoption of the adapter plate 41, the electric connection between the power driving module 40 and the light source plate 10 may be achieved by a connection wire or connection wires, and main bodies of the power driving module and the light source plate can achieve insulating effect and have the function of electric shock protection.

[0028] As shown in FIGS. 1 and 3, the lens unit in the two embodiments of the present invention is a hemispherical lens 24 and is arranged in one-to-one correspondence with the LED light source 11. FIG. 8 illustrates the hemispherical lens 24 applicable in the present invention. The integrated lens assembly 20 is formed by integrally forming the plurality of hemispherical lenses 24. A central portion of an incident surface 28 of the hemispherical lens 24 is concaved to form an accommodating cavity configured to accommodate the LED light source 11 and axisymmetric relative to the hemispherical lens 24. By adoption of the configuration, the incident surface 28 can maximally receive light emitted by the LED light source 11. In addition, a single LED generally adopts 120 DEG Lambert emission; the spacing between two LEDs is formed to allow uniform light to be obtained on a light-emitting surface after the mixing of light; by adoption of the lens, the luminous angle of the LED can be further expanded; and as shown in FIG. 8, the light is deviated towards the direction further away from an optical axis after been refracted two times, so that the requirement of uniform light emission can be satisfied even at lower height, and hence the height of the lamp can be reduced and ultrathin lamp can be obtained.

[0029] As shown in FIG. 8, a light-emitting surface 29 of the hemispherical lens 24 is not a regular hemispherical structure but an approximate ellipsoid structure. Because the accommodating cavity is concavely formed on the incident surface 28, the hemispherical lens 24 is of a structure with a thinner central portion and two thicker sides. A straight line having an included angle θ with the optical axis is led from an origin O of the lens and respectively intersects with the incident surface 28 and the light-emitting surface 29 of the lens; intersection points are respectively M and N; the length of the line segment MN is the thickness t of the lens; and the thickness t of the lens is monotonously progressively increased along with the increase of θ within the range 0 ≤ θ ≤ θ(max), in which θ(max) is ranged from 45° to 90°. Due to the configuration of the hemispherical lens 24, an included angle between paraxial light and the optical axis is increased after the paraxial light runs through the incident surface, and is further increased after the paraxial light runs through the light-emitting surface, so that the hemispherical lenses 24 can have better diffusion effect, and meanwhile, the problem of large paraxial light intensity of the LED light sources can be solved and more uniform flood lighting can be achieved.

[0030] As shown in FIG. 8, the central portion of the light-emitting surface 29 of the hemispherical lens 24 is concaved to form an inverted-cone diffusion portion. The light diffusion function can be achieved by increasing the refraction angle when the light is emitted from the light-emitting surface 29 due to the increasing of the incidence angle when the light is projected to the light-emitting surface 29.

[0031] In the present invention, the incident surface 28 and the light-emitting surface 29 of the hemispherical lens 24 may further be subjected to surface treatment, and the incident surface 28 and the light-emitting surface 29 are respectively treated to form a polished surface and a frosted surface. The function of light diffusion and light uniformity can be achieved by utilization of the scattering properties of the frosted surface.

[0032] The present invention further discloses an LED lamp, which comprises a base taken as a mounting base and the LED light source module having the structure as described above. The LED lamp has the advantages such as simple process, easy assembly, and safety and reliability.

[0033] The lens units in the LED lamp provided by the present invention are integrated to form the integrated lens assembly 20 which covers the outside of the entire light source plate 10 and has the function of electric shock protection. Meanwhile, the principle of mutual attraction between magnetic objects is also utilized; the plurality of accommodating portions 21 are extended outward on the integrated lens assembly 20; the through holes 12 are formed at positions of the light source plate 10 corresponding to the accommodating portions 21; and meanwhile, the magnetic elements 30 are fixed within the accommodating portions 21. The integrated lens assembly 20 and the light source plate 10 are fixedly connected by a detachable connection mechanism such as elastic fasteners 26 and elastic jaws 27 at first, and then fixed by means of the magnetic force of the magnetic elements 30 fixed within the accommodating portions 21 and the magnetic base of the lamp, so that the entire integrated lens assembly 20 and the light source plate 10 can be fixed on the magnetic base of the lamp. The LED lamp adopting the above fixing structure has a very easy assembly process. Moreover, due to the further cooperation of the magnetic elements 30 and/or the elastic fasteners 24 and/or the elastic jaws 25, the structure of the LED lamp is very safe and reliable. Therefore, the LED lamp is an LED lamp having the advantages of simple process, convent assembly and safety and reliability.

[0034] It should be noted that the embodiments of the present invention have better implementations, are not intended to limit the present invention in any way, and may be changed or modified into equivalent valid embodiments by those skilled in the art by utilization of the foregoing disclosed technical contents; and any modification or equivalent change and improvement made to the above embodiments on the basis of the technical essence of the present invention without departing from the content of the technical proposals of the present invention shall still fall within the scope of the technical proposals of the present invention.
