发明名称 Vehicle headlamp
摘要 A vehicle headlamp includes a projection lens through which an optical axis passes. The optical axis extends in a front-and-rear direction of a vehicle. The vehicle headlamp includes a light source disposed on a rear side of a rear focal point of the projection lens; a reflector which reflects a direct light from the light source toward a front direction so as to become close to the optical axis; a shade disposed between the projection lens and the light source and having an edge portion positioned near the rear focal point of the projection lens; and an auxiliary reflector disposed between the projection lens and a shade. The auxiliary reflector reflects a part of the light reflected by the reflector toward the projection lens such that an upward irradiation light is irradiated from the projection lens. The shade shields a part of the light reflected by the reflector and a part of the direct light emitted from the light source and forms a cutoff line of a light distribution pattern. A space is provided between the auxiliary reflector and the shade so as to maintain a light quantity of at least 75% of a main light distribution obtained by the light reflected from the reflector.
