20080239745 | LAMP UNIT OF VEHICULAR HEADLAMP - A lamp unit of a vehicular headlamp includes a projection lens with an optical axis; a light source formed from a semiconductor light-emitting element; a first reflector that reflects light from the light source so as to condense such light on or near the optical axis; and a shade positioned between the light source and the projection lens so as to extend along the optical axis direction. The shade shields part of the light reflected by the first reflector. In the lamp unit of the vehicular headlamp, a shielding surface extends rearward from a front end of the shade, where the shade is positioned near a rearward focal point Rf of the projection lens. The shielding surfaces serve as a second reflector that reflects light from the first reflector toward the projection lens. In addition, a transparent portion is formed on part of the second reflector such that part of the light reflected by the first reflector passes downward of the rearward focal point of the projection lens and is then incident to the projection lens. | 10-02-2008 |
