Paper Abstract

Design of LED optical elements producing uniform illumination in rectangular regions is one of the most actual and challenging problems in development of lighting devices. As a rule, LED optical element has at least two surfaces (inner and outer) that leads to computational complexity of design process and requires application of different optimization techniques. We present a new rapid computational method for automatical design of optical elements with two free-form surfaces which generate uniform irradiance distribution in the rectangular region. Such optical elements have high lighting efficiency (about 92 %) and can be produced by injection molding.
