Abstract

We propose a design method for single reflectors that takes into account extended sources with any arbitrary luminance distribution. This method is suitable for non-uniform prescribed illuminance distributions with arbitrary shapes. We use the method of supporting ellipsoids developed by Oliker in conjunction with optimization in order to control the effects of the source extent. Design examples related to street illumination and LED illumination are presented.
