发明名称 Vehicle headlamp
摘要 A projector-type vehicle headlamp includes a light source which is a line light source extending in a width direction of a vehicle, a reflector, a first auxiliary reflector disposed below the reflector, and a second auxiliary reflector disposed on a front side of the first auxiliary reflector. A sectional shape of a reflecting surface of the first auxiliary reflector taken along a vertical plane that is parallel to an optical axis is a shape of a parabola having an axis line downwardly extending in a forward direction a predetermined downward inclination angle with respect to the optical axis. A sectional shape of a reflecting surface of a second auxiliary reflector taken along the vertical plane is a straight line downwardly extending in a forward direction at a downward inclination angle which is smaller than the predetermined downward inclination angle.
