Modern automobile headlights generally use high-power light sources, such as high-intensity discharge lamps (HID) or light-emitting diodes (LEDs), to meet the growing lighting needs. However, these high-power light sources generate a lot of heat during operation. If it cannot be dissipated in a timely and effective manner, it will have a serious negative impact on the various components of the headlights.
