Description
Technical Field

[0002] LED car lights are an excellent choice for modern car lighting. They are known for their high brightness and low energy consumption, providing drivers with a clear and bright field of vision.

They can perform well in all weather conditions, whether it is rainy, foggy or at night, and can effectively ensure driving safety. They are a technological model in the field of automotive lighting. When existing car lights reduce energy consumption, they use intelligent control to reduce the brightness of the lights in different scenarios to reduce energy consumption. However, LED lights generate heat when working. When the temperature rises to a certain level, the temperature of the LED chip rises, causing more electrical energy to be converted into heat energy instead of light energy, affecting the luminous efficiency of the LED lights. Common fan heat dissipation devices have a complex structure. If heat dissipation is required, turning on the fan consumes a lot of energy. An intelligent heat dissipation structure that uses the airflow generated by the movement of the car to dissipate heat is needed for auxiliary heat dissipation.
