Abstract:
1. A projection-type vehicular headlamp producing a beam having a low-beam light distribution pattern including a cut-off line, comprising: a light source disposed on an optical axis extending generally in a longitudinal direction of a vehicle upon which said headlamp is mounted; a main reflector that reflects light from said light source forward along said optical axis; a projection lens disposed forward of said reflector; a shade disposed between said projection lens and said reflector, said shade blocking part of the light reflected by said reflector so as to form said cut-off line; and at least one additional reflector which forms an additional light distribution pattern superimposed over at least a portion of said cut-off line by reflecting light from said light source forward, said at least one additional reflector being provided on a side of said main reflector, and said additional light distribution pattern being symmetrical around an axis parallel with the cut-off line, wherein said additional light distribution pattern intersects said cut-off line above a center of said additional light distribution pattern and an upper edge of said additional light distribution pattern is above said cut-off line.
