The main function of the heat sink of automotive LED headlights is to dissipate the heat generated when the LED is working, ensuring that the LED works at a suitable temperature, thereby extending its life and maintaining a good lighting effect
The following is an introduction to the relevant situation:
The function of LED headlight heat sink
Heat dissipation: LED headlights generate a lot of heat during operation. The heat sink contacts the air through its large area of aluminum material, quickly dissipating the heat and reducing the operating temperature of the LED
Increase life: Through effective heat dissipation, the junction temperature of the LED can be controlled, light decay can be reduced, and the service life of the LED can be extended
Maintain performance: Good heat dissipation helps to maintain the brightness and light color of the LED and ensure the lighting effect
Design and materials of heat sink
Design: The heat sink is usually designed in the shape of fins to increase the heat dissipation area and improve the heat dissipation efficiency
Material: Common heat sink materials include aluminum, because it has good thermal conductivity and low manufacturing cost
Heat dissipation method
Passive heat dissipation: Heat dissipation through natural convection between the heat sink and the air
Active heat dissipation: In some high-end models, active heat dissipation methods such as fans may be used to enhance the heat dissipation effect
