Automotive projector type headlight

An automotive projector type headlight including a light source, a reflector for reflecting light from said light source forward, a shade for partially shading and contouring the reflected light, and a projecting lens for projecting the contoured light forward, wherein the light source comprises a main filament and a sub-filament extending generally along an optical axis of said light source, the reflector comprises a plurality of radially divided reflective surface portions, with an upper surface portion reflecting light from the sub-filament and converging it to a first converging position located above said optical axis, the shade has a shading edge near to the first converging position, a focus of the projecting lens is near to the shading edge, a lower reflective surface portion reflects light from the main filament, converges it to a horizontally extending second converging position and converges it to a vertically extending third converging position, left and right inner reflective surface portions converge and diffuse thereafter light from both filaments in left and right directions, and left and right outer reflective surface portions are paraboloid of rotation having the focus near to the filaments.

An automotive projector type headlight including a light source, a reflector for reflecting light from said light source forward, a shade for partially shading and contouring the reflected light, and a projecting lens for projecting the contoured light forward, wherein the shade is a generally horizontally disposed plate with a lower surface thereof being formed as a reflective surface, and which reflective surface acts to reflect light rays reflected on the reflective surface and to project them forward and downward.

An automotive projector type headlight including a light source, a reflector for reflecting light from said light source forward, a shade for partially shading and contouring the reflected light, and a projecting lens for projecting the contoured light forward, wherein a portion of the reflector located below the shade is formed as a diffusing and reflecting portion for reflecting light so as to diffuse in a horizontal direction and to direct the light reflected by said portion parallel to an optical axis of said headlight in a vertical direction.

An automotive projector type headlight including a light source, a reflector for reflecting the light forward, a shade for partially shading and contouring the reflected light, and a projecting lens for projecting the contoured light forward, an optical axis of said lens extending parallel and above a optical axis of said headlight wherein a portion of the reflector located below the shade and above said optical axis of said headlight is formed as a diffusing and reflecting portion for reflecting light so as to diffuse in a horizontal direction and to direct the light reflected by said portion downward of the optical axis of said headlight a vertical direction.
