Abstract
A light assembly fixture comprising a heat pipe to dissipate heat from the light emitting device, such as but not limited to a light emitting diode (LED). The assembly further comprises a housing including a front surface, a light emitting device on a first heat spreader remote from the front surface, a first end of a heat pipe in thermal contact with the first heat spreader and the heat pipe extending towards the front surface such that a second end of the heat pipe is in thermal contact with a second heat spreader that is disposed on the housing, wherein the first heat spreader, heat pipe and second heat spreader are configured to provide a thermal path to dissipate heat from the light emitting device.
Claims55
