Abstract
A vehicle headlamp has a segment light source, and a reflector configured to forward reflect light from the segment light source. The segment light source is arranged such that a first predetermined point located at a front end edge of the segment light source is located on a first reference axis. A reflecting surface of the reflector is split into a plurality of reflection regions. At least one of the plurality of reflection regions is constituted as a fan-like reflection region surrounded by a first straight line extending obliquely downward from the first reference axis, and a second straight line extending immediately downward from the first reference axis. The fan-like reflection region is constituted with a curved surface that deflects, diffuses, or reflects the light from the segment light source in a direction orthogonal to the first straight line.
