ABSTRACT:
A vehicle headlight capable of compensating for light intensity of a dark region includes a lamp holder, a light source, a light shield, and a light guide. The lamp holder defines an accommodation space, and includes a reflector and a lens disposed on a front side of the reflector. The light source is installed in the accommodation space and disposed along an optical axis, and light rays emitted from the light source are refracted by the lens and emitted forwards. The light shield is assembled on the lamp holder and located between the light source and the lens, and the light shield is used to shield some of the light rays emitted from the light source. The light guide conducts some of the light rays towards the lens, such that the light rays are emitted forwards and upwards, thereby compensating for the light intensity of the dark region above the optical axis.
