摘要：

Nowadays, freeform optical surfaces are applied for forming of the required LIDC. There are several freeform optics design methods. In case when the optic lens is the lathe object, it is handier to use Light Energy Mapping Design Method. Nevertheless, this method has problem concerned with hotspot appearance in the center. The authors of the article propose an improved algorithm for designing freeform optics with two surfaces with a wide beam angle, designed to form illuminance uniformity and exclude the appearance of hotspot. According to the proposed algorithm, a lens was designed and the possibility of using was evaluated.
