Abstract

Power LED lighting technology is improving rapidly. Because of its advantages, conventional lighting components are currently being replaced with LEDs. Obtaining and controlling characteristics of reflector surfaces, such as luminaire optical efficiency, luminous intensity and luminance distribution, are very important in reflector design for these systems. Reflecting surface forms were computed for power LED systems to give optimum luminaire optical efficiency to provide uniform luminosities. Different power LEDs were considered. The effects of variations of reflector surfaces and materials on luminaire optical efficiency values in reflectors were determined. Luminaire optical efficiencies and illuminance distributions of reflector surfaces were simulated using computer software programs. The purpose of the present study is to provide the required background data involving production of reflector prototypes..
