ABSTRACT:
A light source bulb is fixedly inserted into a lateral direction to the optical axis Ax at a position below an optical axis Ax. Accordingly, a region lateral to the optical axis Ax on a reflection surface of the reflector can be effectively utilized for light distribution control. Furthermore, a first additional reflector having a reflection surface of substantially-spheroidal shape whose first focal point is at a position coincident with the light source is disposed at a position above the optical axis Ax. A second additional reflector36having a reflection surface of a substantially-parabolic vertical cross-sectional profile whose focal point is coincident with a second focal point of the first additional reflector is disposed at a position below the optical axis. As a result, light from the light source is illuminated forward without passing through a projection lens.
