汽车led前大灯哪种散热好?

How is the heat dissipation of LED front lights in cars?

LED front lights are cold sources, if the heat dissipation is not good, they may cause light decay or even stop working. Currently, there are two main ways to cool LED lights: passive solid cooling using weaving bags, and active cooling using fans. When the lights are turned on, the fans start to work.

The heat transfer of heat pipes requires the temperature to reach a certain level and rely on natural air convection to cool the heat through the heat sink and then release it into the air, which has some limitations.相比之下, fans with magnetic suspension run faster and have higher cooling efficiency.

This is mainly based on the observation from the Apa LED dual-lens.
