Patent ID: 8277092

Claim:
A lamp assembly, comprising: a housing having an exterior side surface with a lens abutting edge at one end and a back wall abutting edge at a second end, a back wall with an interior surface and an exterior surface, at least one fin for use in dissipating heat from said housing, wherein the at least one fin extends from the exterior surface of the back wall by a length approximately equal to or less than the length of the exterior side surface from the lens abutting edge to the back wall abutting edge, wherein said housing functions as a heat sink; circuit board assembly positioned adjacent to the interior surface of the back wall of the housing, wherein said circuit board assembly has a drive circuit including at least one current regulator for use in driving a plurality of light emitting diodes; said plurality of light emitting diodes coupled to the circuit board assembly, wherein said light emitting diodes are configured to be driven by a current source regulated the at least one current regulator so as to reduce the amount of heat needed to be dissipated from said housing such that the at least one fin of a length approximately equal to or less than the length of the exterior side surface is sufficient for dissipating heat from the lamp assembly.
