ABSTRACT:
A reflecting surface consists of an inner surface and an outer surface, and a filament is disposed along the optical axis of the reflector. The inner surface produces a projection pattern extended in the horizontal direction. The upper half of the inner surface produces a projection pattern below the horizontal center line. Of the lower half of the inner surface, a subsection located on one side of the vertical center plane of the reflector produces a projection pattern contributing to formation of the inclined cutline, and the other subsection located on the other side of the vertical center plane produces a projection pattern contributing to formation of the horizontal cutline. The outer surface produces a projection pattern concentrated in a central area. The upper half of the outer surface produces a projection pattern below the horizontal center line. Of the lower half of the outer surface, a subsection located on one side of the vertical center plane of the reflector produces a projection pattern contributing to formation of the inclined cutline, and the other subsection located on the other side of the vertical center plane produces a projection pattern contributing to formation of the horizontal cutline.
