Abstract

The comprehensive learning particle swarm optimization technique (CLPSO) is employed to design collimator systems for LED planar light sources, and its fitness function is the merit function of a collimator system which is constructed from sets of light ray displacements and can be obtained from basic geometric-optics analyses. The detailed implementation process is given. A collimator system for a 1 mm diameter round LED consisting of two lenses and a reflector has been designed. The maximum half divergence angle ±4.6 degree of exit light rays can be measured from the experiment, which is agreement with the simulation results..

Keywords
