Vehicle Lamp Assembly

摘要

A lamp assembly having an area of heat concentration is provided with a conductive surface such as an aluminized coating or an insert that increases the emission of heat from the area of heat concentration. An absorptive surface is applied within the housing or on the bezel to increase thermal absorption at a location disposed above the area of heat concentration. Convective air flow within the lamp assembly is induced between the conductive surface to the absorptive surface. Methods disclosed include applying the conductive surface to the area of heat concentration and applying an absorptive surface coating within the lamp assembly.
