     the heat management is the critical factor for high performance operation of led. a new heat management application of refrigerating liquid integrated within a fabricated prototype is proposed and investigated. a series of experiments considering different heights of liquid level were performed to evaluate the heat dissipation performance and optical characteristics of the refrigerating liquid based prototype. the results reveal that the junction temperature decreases as the level of refrigerating liquid increases. the experimental results report that the refrigerating liquid reduces the junction temperature, and can positively influence the luminous radiation performances. an optimization investigation of the proposed solution was carried out to find an optimum thermal performance. the experiments indicated that refrigerating liquid cooling is a powerful way for heat dissipation of high power leds, and the fabrication of prototype was feasible and useful.
