Abstract
A headlamp assembly for a motor vehicle having a light source, a chamber that receives the light source and a cooling channel for removing heat from the chamber. A conductive wall and an insulating wall cooperate to define the chamber and the channel. The conductive wall has a substantially higher thermal conductivity than the insulating wall to promote the heat exchange between the chamber and the cooling channel and to reduce heat exchange between the cooling channel and the relatively hot engine compartment.
