ABSTRACT:
A headlamp for a vehicle adapted to radiate a light beam therefrom exclusively for passing-by vehicles includes a single filament, a main reflector, an auxiliary reflector and a lens. The auxiliary reflector is divided into two parts, i.e., an upper auxiliary reflector and a lower auxiliary reflector along a horizontal line extending through the filament. The upper auxiliary reflector, has a focus which is located at the position in the vicinity of the rearmost end of the filament, while the lower auxiliary reflector has a focus which located at the position in the vicinity of the foremost end of the filament. The auxiliary reflector is basically arranged in the region where the main reflector can not completely collect a light beam radiated from the filament. The upper and lower auxiliary deflectors have an inner diameter and an outer diameter, respectively. The inner diameter is dimensionally defined such that it is located on the lens side outward of line segments extending from the foremost end of the filament to the outermost ends of the main reflector, and the outer diameter is set to substantially the same diameter as that of the region where the function of a part of the main reflector becomes ineffective due to arrangement of sockets for the filament.
