Patent ID: 8378559

Claim:
A lamp, comprising: an LED array; a light reflector; a circular remote vapor condenser positioned below the light reflector, wherein the circular remote vapor condenser having at least one vapor line and at least one liquid line; and a thermo-mechanical system coupled to the LED array, wherein the thermo-mechanical system includes: a top cap thermally coupled to the LED array, the top cap comprising one or more spaces to accommodate a vapor generated from a phase change of a liquid due to a heat emitted from the LED array; a liquid-permeable porous structure coupled to the top cap, wherein the liquid-permeable porous structure causes a capillary force to move the vapor to the vapor line; and a liquid chamber coupled to the liquid-permeable porous structure and hydraulically coupled to the liquid line, wherein the chamber is configured to accommodate the liquid; wherein the circular remote vapor condenser comprises a plurality of spiraling fins to increase a vapor path length to facilitate condensation of the vapor.
