ABSTRACT:
A main reflector has a main reflection-surface based on an ellipsoid of revolution. A light source is arranged substantially at a first focal-point of the main reflection-surface. A shade arranged substantially at a second focal-point of the main reflection-surface cuts off a part of reflected light from the main reflection-surface to form a predetermined main light-distribution-pattern. A projection lens projects the main light-distribution-pattern ahead of a vehicle. A sub reflector reflects a light from the light source to irradiate the light on outer sides of the main light-distribution-pattern as a predetermined sub-light distribution pattern.
