Patent ID: 7866863

Claim:
A vehicle headlamp comprising: a segment light source extending in a vehicle width direction; and a reflector configured to forward reflect light from the segment light source such that a light distribution pattern is formed that has a cut-off line at an upper end thereof, wherein the segment light source is arranged such that a first predetermined point located at a front end edge of the segment light source at end edges thereof in right and left directions in a plan view of the vehicle headlamp is located on a first reference axis extending in the longitudinal direction of a vehicle containing the vehicle headlamp, wherein a reflecting surface of the reflector is split into a plurality of reflection regions, wherein at least one of the plurality of reflection regions, in the plan a front view of the vehicle headlamp, is constituted as a fan-like reflection region surrounded by a first straight line extending obliquely downward from the first reference axis on the side of the first reference axis opposite the segment light source in the right and left directions, and a second straight line extending immediately downward from the first reference axis, and wherein 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, with a paraboloid of revolution that uses the first predetermined point as a first focal point and uses the first reference axis as a center axis formed as a reference plane so as to form the cut-off line.
