DETAILED DESCRIPTION

[0037] The core of the present invention is to disclose a lighting module to reduce the volume of the lighting module.

[0038] Another core of the present invention is to disclose a vehicle lamp comprising the above-mentioned lighting module.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figure 2-Figure 3As shown, an embodiment of the present invention discloses a lighting module, including a lighting module unit 10 and a bracket 20.

[0041] The lighting module unit 10 includes at least one, each lighting module unit 10 is connected to the bracket 20, and a heat conducting plate 30 is provided between each lighting module unit 10 and the bracket 20. Figure 8 shown.

[0042] It should be noted that the heat conducting plate 30 can be a rigid or flexible heat conducting plate. The bracket 20 is preferably made of metal, such as aluminum alloy, and preferably uses an existing bracket 20. To enhance the heat dissipation effect and strengthen the bracket 20, multiple reinforcing ribs can be provided on the bracket 20.

[0043] like Figure 9-10 As shown, the lighting module disclosed in the embodiment of the present invention, compared with the prior art, omits the conventional heat sink 50 in the lighting module unit 10, and the volume is greatly reduced. For a lighting module including multiple lighting module units 10, the improvement effect is even more obvious.

[0044] In the lighting module disclosed in the embodiment of the present invention, heat generated by the lighting module unit 10 is conducted to the bracket 20 via the heat conducting plate 30. Heat is dissipated through the bracket 20, reducing the size and weight of the lighting module and adapting it to narrow and compact vehicle headlight designs. In addition to its conventional support function, the bracket 20 also serves as a heat dissipator, further enhancing the functionality of the bracket 20 and making the lighting module more integrated.

[0045] In some specific embodiments, the structural diagram of the lighting module unit 10 is as follows: Figure 1 As shown, the lighting module unit 10 specifically includes a light board 11, a reflective element and a lens. Of course, the lighting module unit 10 may also include a focusing element and a collimating element, which can be specifically determined according to actual needs.

[0046] In some specific embodiments, the bracket 20 is arranged in an L-shape, such as Figure 3 As shown, those skilled in the art can determine the shape of the bracket 20 according to the shape requirements of the lighting module.

[0047] In the lighting module disclosed in the embodiment of the present invention, the heat conducting plate 30 is preferably a flexible heat conducting plate. The flexible heat conducting plate has a certain flexibility and can produce a certain deformation, and can adapt to the fine adjustment of the angle of the lighting module unit 10 relative to the bracket 20.

[0048] like Figure 3-Figure 4As shown, in some specific embodiments, the heat conducting plate 30 includes a heat conducting plate body 31, a first connecting portion 32 provided at a first end of the heat conducting plate body 31, and a second connecting portion 33 provided at a second end of the heat conducting plate body 31. Figure 5-Figure 6 As shown, the lighting module unit 10 includes a lamp board 11, which is connected to a first connecting portion 32, and a bracket 20 is connected to a second connecting portion 33. Preferably, the first connecting portion 32 is in surface contact with the lamp board 11, and the second connecting portion 33 is in surface contact with the bracket 20. The surface contact can increase the heat transfer area and improve the heat dissipation efficiency.

[0049] like Figure 5-Figure 6 As shown, to enhance heat dissipation, in some embodiments, the first connection portion 32 is disposed on the front and back sides of the light-emitting element 111 on the lamp board 11. The lamp board 11 is typically made of a copper or aluminum substrate, and the back side of the light-emitting element 111 is where the heat is most concentrated. This approach can improve heat dissipation efficiency.

[0050] In some specific embodiments, the light board 11 is welded to the first connection portion 32; and / or the bracket 20 is welded to the second connection portion 33. Welding is a more secure connection. Of course, the heat conducting plate 30, the light board 11, and the bracket 20 can also be connected by adhesive bonding, such as with thermally conductive silicone.

[0051] In some specific embodiments, Figure 7 As shown, the heat conducting plate body 31 is arranged in a rectangular shape, the first connecting portion 32 is arranged obliquely with the heat conducting plate body 31, so that the first connecting portion 32 can adapt to the arrangement of the light board 11 in the lighting module unit 10, and the second connecting portion 33 is arranged perpendicular to the heat conducting plate body 31. In other specific embodiments, such as Figure 3 As shown, the second connection portion 33 can be bent, and the second connection portion 33 shown in the figure is U-shaped. It should be noted that the shape of the heat conducting plate 30 here is only an example, and can be specifically determined according to the shape and arrangement of the light board 10 in the lighting module unit 10 and the shape of the bracket 20.

[0052] To facilitate assembly and disassembly, in some specific embodiments, the lighting module unit 10 and the bracket 20 are connected in a detachable manner, and can be connected by fasteners or snap fasteners.

[0053] like Figure 3As shown, in some specific embodiments, the lighting module unit 10 is connected to the bracket 20 via a connecting assembly 40. The connecting assembly 40 specifically includes a fixing member 41, a first adjusting member 42, and a second adjusting member 43. The first adjusting member 42 and the fixing member 41 are arranged collinearly along a first direction, and the second adjusting member 43 and the first adjusting member 42 are arranged collinearly along a second direction. The lighting module unit 10 is connected to the bracket 20 via the fixing member 41. The first adjusting member 42 is used to adjust the angle of the lighting module unit 10 on the bracket 20 along the first direction, and the second adjusting member 43 is used to adjust the angle of the lighting module unit 10 on the bracket 20 along the second direction. The first direction and the second direction are perpendicular. Specifically, the first direction refers to the extension direction of the y-axis shown in the figure, and the second direction refers to the extension direction of the x-axis shown in the figure.

[0054] The fixing member 41, the first adjusting member 42, and the second adjusting member 43 are preferably screws. The bracket 20 is provided with a threaded hole for the fixing member 41, a first mounting hole for the first adjusting member 42, and a second mounting hole for the second adjusting member 43. In some specific embodiments, the lighting module unit 10 is provided with a mounting slot capable of accommodating the first adjusting member 42. The provision of the first adjusting member 42 and the second adjusting member 43 can correct for errors caused by manufacturing and assembly of the lighting module.

[0055] In some other specific embodiments, the first mounting hole is a first waist-shaped hole extending along the second direction, and the second mounting hole is a second waist-shaped hole extending along the first direction.

[0056] In the lighting module disclosed in the embodiment of the present invention, the heat conducting plate 30 includes at least one of a phase change heat conducting plate, a phase change heat conducting pipe and a heat conducting cable. The heat conducting cable can be made of metal or non-metal, preferably metal.

[0057] In addition, an embodiment of the present invention further discloses a vehicle lamp, which includes the above-mentioned lighting module, and therefore has all the technical effects of the above-mentioned lighting module, which will not be described in detail.
