Abstract

A design method of collimated LED secondary optics with freeform surface is proposed. This method based on ray tracing can ensure the optical requirements and surface smoothness requirements simultaneously, which can simplify the freeform surface design process and realize programming design. The manufacture of freeform surface is the premise for its application. Based on the machinability of freeform surface, the proposed design method can flexibly change design parameters according to processing requirements with high degree of design freedom. The correctness of the method is verified by optical simulation and experiments.
