ABSTRACT:
The automotive headlight of projector type comprises a reflector, a lamp bulb as light source disposed near the focus of said reflector, a convex lens which projects frontwardly the light emitted from the lamp bulb, reflected by the reflector and then converged to a predetermined light collecting area, and a light transmitting means device through which the light is projected directly and frontwardly from the lamp bulb. The light emitted directly from the lamp bulb is positively projected frontwardly through the light transmitting device without passing through the convex lens. Therefore, the zones surrounding the illuminated zone are blurred. The luminous intensity of the zone near the boundary between the illuminated and non-illuminated zones can be gradually decreased going outwardly away from the projector axis into the non-illuminated zone without any influence on the illumination distribution of the zone illuminated by the light projected through the convex lens.
