[0002] As the concept of energy conservation and environmental protection has become more popular, LED lamps have been widely used in automotive lighting systems due to their advantages such as high efficiency, energy saving, long life and fast response. However, there are still some technical problems in the use of existing automotive LED lamps, which affect their performance and life.

[0003] First, LED lamps generate a lot of heat when working. If the heat is not dissipated in a timely and effective manner, the excessively high temperature will cause the light efficiency of the LED chip to decrease, thereby shortening the service life of the LED lamp.
