摘要

In a light chamber formed by a housing case and a lens cover of a headlamp assembly, a projection lens and a light source are arranged in order along an optical axis of the light source from a front side of the light chamber. Radiating fins of a plate shape is vertically placed in the light chamber and radiate heat energy generated by the light source. A heat exchange chamber is formed in a ceiling wall of the housing case above the radiating fins. The heat exchange chamber has a concave shape from the ceiling wall of the housing case, and is open toward the radiating fins side.
