Abstract

An ab initio design of a light emitting diode (LED) array for achieving uniform illumination is presented. An optimization technique based on evolutionary programming has been developed to facilitate the search for an optimal array in the hyperspace formed by a number of LEDs and spacing between them. Numerical results are presented for a regular and irregular array with LEDs having Lambertian and special types of light distribution.
