ABSTRACT:
The projector type vehicle headlamp includes a light source, a reflector including a reflection surface for reflecting light from the light source, and a condenser lens that irradiates reflected light from the reflection surface forwards. The reflection surface includes a plurality of segments, and is formed of a free-form surface obtained by deforming a reference ellipsoid of revolution. The light source is arranged between a first focal point of the reference ellipsoid of revolution and the condenser lens, closer to the first focal point than to the condenser lens. Segments forming one end and other end portions of a light distribution pattern includes a wide area-illuminating reflection surface that makes the one end and the other end portions substantially a rectangular shape, where the other end portion is opposite to the one end portion with respect to a center of the light distribution pattern.
