Patent ID: 7806572

Claim:
A headlamp assembly, comprising: a base member; a transparent cover member joined to the base member; a light engine housing including: a light engine employing semiconductor light sources; a lens, light from each of the semiconductor light sources operable for passing through said lens such that said lens is operable to focus light from the semiconductor light sources into a desired beam pattern; a heat rejection structure extending outside of the housing to remove heat from the semiconductor light sources; a mounting flange and flexible bellows moveably mounting the light engine housing with respect to the base member, wherein the base member, transparent cover member and light engine housing form an optics chamber isolated from the surrounding environment; a lens carrier joined to said light engine housing, said lens carrier and said light engine housing forming a closed volume within said optics chamber; and a rear member connected to the base member and the transparent cover member to define a plenum chamber about the heat rejection structure, the plenum chamber including at least one inlet to admit cooling air to the plenum chamber and at least one outlet to exhaust cooling air from the plenum chamber.
