First Claim
Patent Images
1. A lamp comprising:
- an enclosure comprising a reflector and a lens, the reflector being exposed to the ambient environment and being made of thermally conductive material;
a base;
at least one LED located in the enclosure and operable to emit light when energized through an electrical path from the base;
a heat sink comprising a heat dissipating portion that is at least partially exposed to the ambient environment and a heat conducting portion that is thermally coupled to the at least one LED, the reflector being thermally coupled to the heat sink and being 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.

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.
