ABSTRACT:
A pair of converging sections is provided on right and left sides of the principal optical axis of a reflector, and an area excluding the converging sections is made a horizontally diffusing region. Rays reflected by the converging sections contribute to formation of a converged portion of a light distribution pattern, and rays reflected by the horizontally diffusing region contribute to formation of a horizontally diffused portion. The converging sections have an elliptical paraboloid or paraboloid-of-revolution surface. The horizontally diffusing region is so constructed that the horizontal diffusion angle increases with the distance from the principal optical axis in the horizontal direction.
