Fan vs fanless led headlights
When the LED headlights are turned on, they will generate a lot of heat. If there is no heat dissipation, it will affect the life of the lights. Therefore, it is generally equipped with a small cooling fan with high air volume.
"All aluminum" heat dissipation refers to heat sink type heat dissipation. Previously, heat sink type heat dissipation was used.
The latest LED headlights now use a fan to dissipate heat, which is a kind of active heat dissipation with higher heat dissipation efficiency. Because of the use of a fan to dissipate heat, the heat of the headlights can be dissipated in time, lowering the temperature, so the brightness can be increased. Since the use of fans for heat dissipation, three-sided LED headlights have been introduced. The brightness is very high, almost as bright as xenon lamps. This was unimaginable when heat sinks were used to dissipate heat.
When the heat sink is radiating heat, it can only emit light on two sides. If the temperature of the three sides is too high, the light cannot be dissipated in time, and the light will not be able to stand it.
Therefore, in general, the fan heat dissipation is more efficient and more advanced.
