摘要：
A bifunctional vehicle headlamp is described. In one embodiment, a headlamp comprises a light source and a reflector, which cooperate to form a light pattern, a lens positioned forward of the reflector and configured to project a desired beam pattern, and a light shield disposed between the lens and the reflector. The light shield has a first shade that selectively blocks a first portion of the light pattern to form a first beam pattern, and a second shade that selectively blocks a second portion of the light pattern to form a second beam pattern.
