Abstract

In this paper an optimal power allocation scheme is proposed to acheive uniform illuminance. Regular arrays and random geometries are considered for an arrangement of the source LEDs. Uniform illuminance is accomplished by considering the variance of the received power on the receiver plane as metric and framing it as a convex optimization problem. Numerical results show that the quality factor of random geometries are superior to fixed geometries. While preserving uniformity, the cost of the system can be reduced when random geometries are used. © 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreement
