Vehicle headlamp
A vehicle headlamp comprises a reflector (30) having about a reflecting parabolic face (33), and a lens (20) made of synthetic resin and attached to the front end of said reflector (30). The vehicle headlamp further includes a lamp (50) held by said reflector, at least one filament (55) in said lamp...

| description | A vehicle headlamp comprises a reflector (30) having about a reflecting parabolic face (33), and a lens (20) made of synthetic resin and attached to the front end of said reflector (30). The vehicle headlamp further includes a lamp (50) held by said reflector, at least one filament (55) in said lamp positioned ahead the focussing point (f) of said reflector, and a zone (40) formed on the reflecting face where a mean is arranged to reduce the amount of light coming from the filament onto the lens at an upper area (A) thereof, said zone being positioned above the lamp and along a axis vertically passing through an optical axis (X). Said light reducing means is intended to reflect light either irregularly or diffusedly. The irregularly reflecting means comprises using no undercoat which serves to make the reflecting coat flat and smooth, or making the reflector body rough and uneven and then applying reflecting coat onto this rough and uneven portion with the undercoat interposed therebetween. The diffusedly reflecting means comprises forming slanted faces on the inner face of said reflector body and applying the reflecting coat onto these slanted faces with the undercoat interposed therebetween. |
