Abstract: A thermally conductive lamp reflector is provided that dissipates heat from a light source within the reflector. The reflector assembly includes a shell having a metallized layer on its surface. The shell is made from a composition including about 30% to about 80% by volume of a base polymer matrix and about 20% to about 70% by volume of a thermally conductive filler material. The reflector has a thermal conductivity of greater than 3 W/m° K and preferably greater than 22 W/m° K. The reflectors can be used in automotive headlamps, flashlights, and other lighting fixtures. A method of forming the lamp reflector is also provided.
