Abstract: A modulized LED apparatus includes a container having a chamber wall with a chamber therein, a transparent surface thereof for the container to be pervious to radiant energy and/or light. The container has an optical processing area for converging, collecting or diffusing radiant energy and/or light. A liquid refrigerant and an evaporator including a heat conductor unit and a capillary unit are in the chamber, and the capillary unit has a portion contacting the liquid refrigerant. With the heat generated by an operating LED device, the evaporator evaporates the liquid refrigerant into a gaseous phase, which then condenses on the chamber wall and thus transfers heat to the chamber wall for dissipating, and the condensed refrigerant is evaporated again by the evaporator again into the gaseous phase. Due to this thermal recycling, the refrigerant continuously transfers heat from the LED device to the ambient environment.
