1. A lighting assembly for cooling a light source, the lighting assembly comprising:
a. a light source having a vertically aligned thermal exchange surface; b. an evaporator having a side thermal exchange surface thermally coupled to the vertically aligned thermal exchange surface of the light source, wherein the evaporator comprises a reservoir and a fluid within the reservoir, the evaporator is configured such that at least a portion of the fluid is vaporized by heat transferred from the light source; and c. a cooling loop coupled to the evaporator, wherein the cooling loop comprises a transfer pipe coupled to the evaporator, a radiator coupled to the transfer pipe, and a return pipe coupled to the radiator and to the evaporator, wherein the return pipe includes a first end coupled to the radiator and a second end coupled to the evaporator, the return pipe is configured and aligned having the first end of the return pipe positioned higher than the second end of the return pipe and an entirety of the return pipe is positioned higher than a bottom surface of the evaporator thereby enabling gravity feeding of fluid from the radiator to the evaporator, further wherein the radiator is configured to receive vapor from the evaporator via the transfer pipe and to condense the vapor to fluid, and the radiator is configured to gravity feed the fluid to the return pipe. |
