Led Headlight: Which one is better, fan cooling or heat sink cooling?

Posted by carlzhou9 on January 14th, 2020

Fan cooling is the addition of a small fan in the led heatsinks. When the LED is lit up, the small fan in the tail also works with the LED. Through the fan, the heat of the aluminum seat is released into the air in the form of air convection.

LED headlight is sensitive to temperature changes. If the LED is continuously lit at high temperature, it will generate more heat. If there is no heat dissipation, it is easy to reduce the power and its lifespan. To some extent, the lifespan of a headlight is directly based on its heat dissipation.

Fan cooling: fan is the active cooling, when the light is lit, the fan of the headlight starts to operate. In terms of structure, the LED headlights of the fan have a compact structure, which can be installed in many vehicles. There is no need to punch holes, and the original structure will not be damaged. Since LED heat sink is generally longer, many vehicle models need to be punched holes on the back cover.

Heat sink cooling: When heat sink cooling works, it needs to reach a certain temperature relying on the natural convection of the air, through the heat sink to the air. Due to the lack of space, the heat sink can not be opened, after the heat sink is installed. And then the cooling system will be effected.
