[0002] With the emergence and popularization of automobiles, various headlights adapted for automobiles have also been developed. Due to users' demand for lighting, LED headlights have developed in the direction of high power. Many high-power LED headlights increase the brightness and power of LEDs by increasing the driving current. As the current increases, it will cause heat accumulation inside the chip. If the heat dissipation problem of LEDs cannot be solved, it will lead to a series of problems such as LED wavelength drift, decreased light output efficiency, accelerated aging of phosphors, and service life. Therefore, if the heat dissipation problem of headlights is not handled in time, it will cause the headlights to fade and reduce the service life of the headlights. Among them, the headlight radiator plays a greater role in heat dissipation.

[0003] However, the existing car lamps have the problems of single structure and poor heat dissipation effect during the heat dissipation process. Therefore, in order to overcome this problem, a car lamp kit with better heat dissipation effect is urgently needed. Utility Model Content
