In this paper we study the conditions for the use of different profiles radiator for cooling high power LEDs. Computer modeling of heat transfer processes and experimental study of thermal conditions in the real radiator assembly with LEDs. Showed the correlation between simulation results and experiment. Confirmed the adequacy of using a computer model.
In this paper we study the temperature regimes of power LEDs for use in various types of light-emitting devices. It is shown that the use of thermoelectric coolingbatteries for high-power LEDs are not very effective. The most significant contribution to LED cooling is achieved by increasing the size of the radiator. The results of this study is needed for the subsequent mathematical modeling and control systems operating modes of light-emitting systems
