Abstract
Provided is an intelligently-connected vehicle LED headlight using graphene, which comprises an imaging lens assembly (9, 5, 6, 7), an LED light source (1), and a heat dissipation assembly (2, 3, 4), wherein the imaging lens assembly (9, 5, 6, 7) is connected to the LED light source (1), and the LED source (1) is connected to the heat dissipation assembly (2, 3, 4). The light distribution manner of the light source of the vehicle headlight is changed from emitting light by a reflector to emitting light by imaging, so that the light emission efficiency is improved by more than 30%. Further, a graphene heat dissipation material is used in the vehicle headlight to dissipate heat, and accordingly the heat dissipation capability of the lamp can be better improved, thereby prolonging the service life of the vehicle headlight.
