Determination of reflecting surface profiles and light efficiency of power led systems in terms of light output optimization

Recently, due to its benefits, LED (Light Emitting Diode) technology has replaced conventional lighting systems. Efficient use of LEDs is of vital importance in terms of optimizing the usage of LEDs. The intended output can be obtained when electrical, thermal and optical conditions for LED are optimized. In this study, thermal and electrical productivity values are acceptable as far as today's conditions are concerned. No methods have been so far proposed in the literature about optical design that supplies LED enlightenment. Because, due to their structures, LEDs and other conventional lightening systems are different, and new methods are needed. In this framework, expedient reflecting surface profiles must be obtained in order to give right direction to LED light and gain proper optical output. In this study, a new method is created to obtain reflecting surface profiles that provide the enlightenment in respect to LEDs' optical features. So as to use this method, LED's characteristics, aspheric surface parameters defined as reflector surface, reflecting surface parameters are determined. In addition, aspheric reflector surface definitions are made for reflectors. Lux, light distribution, reflecting surface optical productivity, maximum and minimum enlightenment values of enlightenment surfaces on the defined surfaces is acquired. LTI Photopia, version 2014, optical design software was used for optical analysis. The same method was used to apply multiple LED array. LED arrays with armature structures were created to minimize the multiple source shadow effect. Fresnel lenses were designed to optimize and routinize light distribution. In this respect, data obtained from analyses were analyzed. This study aims to benefit from LED technology and to feasibly apply this method.
