Abstract
We propose a complementary optimization method to design a freeform lens for uniform illumination with extended LED sources. With this method, a primary freeform lens is first constructed based on a source-target energy mapping approach; then a complementary illuminance on the target plane is introduced to optimize the primary freeform lens so that it can produce uniform illumination with an extended COB LED. The computer simulation results show that the illuminance uniformity of the optimized lens can be improved nearby 30% as compared with that of the primary lens; meanwhile, the optical efficiency achieves above 94%..
