Abstract :
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.
