Layout design of LEDs in an LED-based lighting system with a conventional Fresnel lens to optimize the illuminance and uniformity by using Genetic Algorithm and Tabu Search

摘要

To let the economic and popular conventional Fresnel lens be available to a lighting system with multiple LEDs, we develop an efficient Genetic Algorithm to arrange LEDs' locations and a Tabu Search Algorithm to adjust their orientations to optimize illuminance and uniformity of a multiple-LED lighting system.
