Abstract

The invention discloses a vehicle LED (light emitting diode) headlamp heat dissipation system and a vehicle headlamp. The heat dissipation system comprises an LED light source module, a heat dissipation channel and a bladeless fan; the heat dissipation channel is provided with an air inlet and an air outlet; the air inlet faces the front side of a vehicle; the air outlet faces the rear side of the vehicle; the LED light source module is arranged on the outer wall surface of the heat dissipation channel; the bladeless fan is arranged in the heat dissipation channel; an air inlet of the bladeless fan corresponds to the air inlet of the heat dissipation channel; and an air outlet of the bladeless fan corresponds to the air outlet of the heat dissipation channel. The vehicle headlamp comprises a lamp shell, a light transmitting surface cover and the heat dissipation system. A strong convection active heat dissipation mode is adopted, heat generated during working of the LED light source module can be dissipated timely without the aid of a heat sink, the problems that light failure is caused and the service life is shortened due to LED heating are solved, the weight of the headlamp can be reduced, the size of the headlamp is reduced, the cost is saved, and the diversified design of the headlamp is implemented.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a vehicle LED headlight cooling system and a vehicle headlight. Background technique [0002] At present, most vehicle headlights use xenon lamps, which have complex circuit structures and require high-voltage circuits, which are relatively dangerous, and have disadvantages such as low conversion efficiency, short service life, weak penetrating power to fog, and high power consumption. . The LED light source has the advantages of small size, long life, fast response, stable performance, high reliability, low required voltage and low current. Therefore, in recent years, people have begun to try to replace xenon lamps with LED light sources. However, the lifespan and luminous efficiency of LEDs are closely related to whether the heat dissipation effect is good or not. This is because the junction temperature of LEDs will be high if the heat dissipation is not good, and the lifespan and lu...
