Paper Abstract

We present a new strategy to calculate an optimized refractive freeform surface for illumination purposes with a LED source. The goal of this paper is to present a new iterative flux based strategy to design plastic lens for LED lighting solutions. The new strategy considers the energy emission pattern of the LED and adjusts a plastic refractive surface to accomplish the target intensity distribution. This paper is divided in four parts, a brief introduction to LED systems and reviewing optical design strategies, the method of calculus is exposed in the second part, third part presents the results for a particular refractive optical design developed by new presented algorithm and finally, a set of conclusions about strategy is showed in fourth part.
