Abstract: Dynamic heat sink that uses a thermoelectric cooler, such as a Peltier Junction, to move the heat at a LED junction to the other side of the cooling chip. This would allow the LED to run with more current in a much smaller area than a passive metal heat sink without burning out the junctions. The Present Invention would therefore permit a compact light device comprising a plurality of LED's to be constructed. Such a light device would be competitive with standard fluorescent bulbs by outputting light of equivalent brightness with less power dissipation.

Abstract: The present invention replaces a standard size halogen tungsten lamp spotlight or floodlight with a much cooler LED lamp that also fits into existing housings. However, the LED's still need to be cooled. The Present Invention mounts up to three LED's into a special reflector with a plurality of specially designed heat sinking fins arranged in a star configuration. Peltier junctions may also be used to further direct heat to the fins.
