Patent ID: 8651704

Claim:
A system for cooling solid-state lighting fixtures, the system comprising: a solid-state light source having one or more light-emitting diodes (LEDs) and a heat source, wherein at least a part of the heat source is associated with a heat sink to dissipate heat generated by the heat source; an enclosure having a plurality of portions with a first portion of the plurality of portions being at least partially transparent and one of the plurality of portions including a fluid transfer conduit interface, wherein the solid-state light source is mounted within the plurality of portions to form two sections of the enclosure that are separated from one another, the LEDs are located in the first section facing the first portion of the enclosure that is at least partially transparent and the heat sink is located in the second section of the enclosure; and a fluid transfer conduit connected to the enclosure via the fluid transfer conduit interface to allow fluid to transport heat generated by the heat source away from the heat sink of the solid-state light source; wherein the second section of the enclosure encases the heat sink within a heat chamber, and wherein the heat chamber includes inside surfaces and external surfaces with a gap between the inside surfaces and the external surfaces, the inside surfaces are thermally conductive, the external surfaces are thermally insulated, and the fluid is able to flow through the gap between the inside surfaces and external surfaces extracting heat being dissipated by the heat sink.
