ABSTRACT:
Herein disclosed is a vehicular headlamp which comprises a concave light reflector having a focus and a light ray converging point, the converging point being positioned in front of the focus with respect to the reflector; a first light source located on the focus; a second light source located behind the focus; a cover member covering front and lower portions of the first light source; a first shade member positioned in the vicinity of the converging point of the light reflector, the first shade member having an upper edge positioned near an optical axis of the light reflector; a second shade member located in the vicinity of a subconverging point at which light rays produced by the second light source and reflected by the light reflector are converged; and a converging lens arranged in front of the first shade member in such a manner that a focus of the lens is positioned on the upper edge of the first shade member. The first and second shade members are respectively formed with mutually facing first and second light reflecting surfaces. The first and second light reflecting surfaces are so arranged and constructed that the light rays from the light reflector are reflected by the second and first reflecting surfaces in this order and directed toward the converging lens.
