Abstract

Luminous power LED technology has been improving quite fast and it will replace completely the lighting components that are used currently in the present decade due to its lighting advantages. This study was carried out to determine illumination efficiencies of power LED drivers and optics. The buck-based type LED driver was selected for this study. On this way, power LED driver circuit was designed using switching current regulator and circuit component values were computed for maximum light output efficiency. A reflector which will enable uniform distribution of the maximum power LED illumination to be obtained by using this driver circuit was investigated. In this case, diffusers and Fresnel lenses were proposed depending on the use. Diffusers can be used for indoor iluminations combined with reflectors. To this end, also Fresnel lenses were investigated.
