Abstract

A lamp having an enclosure with a reflector and a lens where the reflector is made of thermally conductive material. A base is coupled to the enclosure. An LED is located in the enclosure and emits light when energized through an electrical path from the base. A heat sink having a heat dissipating portion that may be at least partially exposed to the ambient environment and heat conducting portion that is thermally coupled to the LED. The reflector is thermally coupled to the heat sink and is exposed to the exterior of the lamp such that heat from the heat sink may be dissipated to the ambient environment at least partially through the reflector.
