Lighting Device Using Short Thermal Path Cooling Technology and other Device Cooling By Placing Selected Openings on Heat Sinks

Abstract

A novel heat sinking technology, uniquely adaptive to LED lighting devices in a generally LED array format containing multiple openings on said heat sink's base portions and optionally fin portions providing “short path cooling” technology. The “short path cooling” technology is thoroughly taught with multiple examples. Also taught, are methods of heat sink area maintenance when said openings are placed on said heat sinks. Indeed, even surface area increases are shown to be possible when multiple openings are placed on said heat sinks. Lastly, other non-LED semiconductor cooling is discussed and illustrated in various figures using said “short path cooling” technology.
