Abstract
A method for design of refractive optical element producing the prescribed irradiance distribution with large angular dimensions from extended light source is presented. The method is based on the gradient optimization of the refractive surface represented as a bicubic spline in spherical coordinates. The secondary LED optic that produce uniform irradiance distribution in the rectangular region extended light source is computed. The energy efficiency of the optical elements is more than 75 %; the non-uniformity of the generated irradiance distribution is less than 10 %.
