[0037] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a vehicle light source structure provided by the utility model includes a heat dissipation bracket, an LED light source, a metal wire, and a PCB board, wherein the PCB board is fixed to the heat dissipation bracket by a fastener, the LED light source chip is mounted on the heat dissipation bracket, and the metal wire connects the LED light source and the PCB board. An avoidance hole is provided on the heat dissipation bracket below the metal wire.

[0039] This application directly mounts the LED light source on the heat dissipation bracket, integrates the LED light source patch area, is compatible with different LED light source positions, and adopts the structure of the integrated LED light source patch platform to solve the compatibility problem of different LED light source patches, achieving the effect of platformization of the heat dissipation bracket, which not only improves the heat dissipation efficiency of the entire system and reduces the weight of the heat dissipation bracket, but also increases the flexibility of product design by installing an additional platform module assembly on this basis. By applying the patch technology of thermoelectric separation, the module volume is smaller and the compatibility of LED light source patches is greater. Therefore, by designing a composite application of a smaller light source module or main radiator, the design of the headlight light source is more thermally efficient and more flexible, and under the premise of different shapes and functional requirements, the platform application is still maintained, which also reduces costs. The LED light source is bonded to the mounting surface of the heat dissipation bracket with a high thermal conductivity glue, which has a higher heat dissipation efficiency. The LED light source is connected to the PCB board through a metal wire, and the PCB board is mounted on the surface of the heat dissipation bracket through screws.

[0040] Specifically, the heat dissipation bracket includes a main heat dissipation bracket 3, the LED light source includes a first LED light source 71, the metal wire includes a first metal wire 81, and the PCB board includes a first PCB board 101. The first PCB board 101 is fixed to the main heat dissipation bracket 3 by a first screw 91, the first LED light source 71 is mounted on the main heat dissipation bracket 3, and the first metal wire 81 connects the first LED light source 71 and the first PCB board 101. It should be noted that the two first metal wires 81 can be connected between the first LED light source 71 and the first PCB board 101 in an eight-shaped shape or in parallel.

[0041] The heat dissipation bracket also includes an auxiliary heat dissipation bracket 6, which is installed on the main heat dissipation bracket 3 through fasteners; the LED light source includes a second LED light source 7, the metal wire includes a second metal wire 8, and the PCB board includes a second PCB board 10; the second PCB board 10 is fixed to the auxiliary heat dissipation bracket 6 through a second screw 9, the second LED light source 7 is patched on the auxiliary heat dissipation bracket 6, and the second metal wire 8 connects the second LED light source 7 and the second PCB board 10.

[0042] The first LED light source 71, the first metal wire 81 and the first PCB board 101 are arranged on the front and / or back of the main heat dissipation bracket 3. A plurality of auxiliary heat dissipation brackets 6 are arranged at intervals on the main heat dissipation bracket 3. A cut-off line structure 14 is arranged on the main heat dissipation bracket 3. If the design requires a single low beam or a high and low beam integrated function, the cut-off line structure 14 is retained. If the design requires a single high beam function, the cut-off line structure 14 is not required, thereby removing the traditional light shielding sheet and installation, and reducing the cost.

[0043] This application can produce a smaller independent platform light source assembly through higher heat dissipation efficiency. In project design, such as single low beam, single high beam, and high and low beam integrated, the platform light source assembly can be directly used to achieve optical design under different requirements, which is more adaptable to the shape of lens 1 and more flexible in design. Different models of LED light sources or different numbers of LED light sources can also be set according to design requirements. Not only can the functions of single high beam, single low beam, and high and low beam integrated be realized on the module, but also functions such as atmosphere lights, daytime running lights, signal lights, and animation effects such as flowing water can be integrated.

[0044] The ADB function can also be achieved through a denser arrangement of LEDs. The main heat sink bracket 3 itself can also be designed as a light source assembly, and the design of the platform light source assembly can make the functional distribution more combinatorial and flexible during design. The LED for the high beam function can be arranged on the lower side of the main heat sink bracket 3 to make the heat dissipation efficiency higher. The cut-off line structure 14 is integrally formed on the main heat sink bracket 3 through a casting process, which reduces the cost compared to the installation of traditional additional light shielding sheets.

[0045] It should be further explained that in conventional designs, the design of arranging single LEDs side by side will cause the heat radiation range to overlap, resulting in the degradation of LED performance or even mutual destruction, such as Figure 6 As shown, the technical solution of the present application can effectively solve the problem of a single LED obtaining more independent heat radiation ranges in a more compact LED arrangement by arranging the LED structure in a staggered manner, effectively improve the heat dissipation efficiency, and solve the problem of reduced efficiency or even melting of the LED due to heat superposition caused by overly dense LED arrangement.

[0046] When more rows of LEDs are required, the LEDs can be Figure 7The LEDs are arranged in the manner shown in the figure, and a PCBA is set on the opposite side to drive the corresponding LEDs. In this way, two PCBAs can drive three rows of LEDs to achieve a higher density LED arrangement, thereby achieving a higher quality adaptive high beam function.

[0047] According to an optical system provided by the utility model, it also includes a reflector 2 and a lens 1. The reflector 2 is mounted on the main heat dissipation bracket 3 by fasteners, and the lens 1 is mounted on the reflector 2 by buckles 5. The optical system integrates the functions of single high beam, single low beam, and high and low beam in one, and can also integrate atmosphere lights, daytime running lights, signal lights, and animation effects such as flowing water. The optical system achieves the ADB function through LED arrangement. Specifically, the main heat dissipation bracket 3 is provided with corresponding mounting structures for various parts. After the light source assembly is installed, the reflector 2 can be installed on the main heat dissipation bracket 3 by the third screw 4, and then the lens 1 can be installed on the reflector 2 by the buckle 5, thereby completing the assembly of the entire module unit.
