Abstract：High-power LED usually is in small size and big current，most of the input power converted into thermal energy．SO heat dissipation is the key technology to'be solved．This paper introduces the method of thermal design and module of thermal resistance of High-power LED；and describes heat dissipation design for illumination Highpower I D arrays．
The results from the simulation and analysis and the assessment experiment had proved that the method and the radiator design met the demand of heat dissipation of the LED arrays．
Key words：high-power LED；heat dissipation design；simulation analysi
