ABSTRACT:
An automotive projector type headlight including a light source, a reflector for reflecting the light forward, a shade for partially shading and thus contouring the reflected light, and a projecting lens for projecting the contoured light forward. The light source comprises a main filament and a sub-filament extending generally along the optical axis. The reflector has a plurality of radially divided reflective surface portions. An upper reflective surface portion reflects the light from the sub-filament and converge it to a first converging position located above the optical axis. A shading edge of the shade is positioned near to the first converging position. The projecting lens has a focus near to the shading edge. A lower reflective surface portion reflects the light from the main filament, converges it to a second converging position extending horizontally and converges the light to a third converging position extending vertically. Left and right reflective surface portions act to converge the light from both filaments and to diffuse it thereafter. And a portion of the reflective surface is formed into paraboloid of rotation having the focus near to the filaments.
