Abstract

Due to the increased quality requirements of lighting environment, high-performance LED mixed-light lighting research has become a trend. According to the principle of imaging optics, an optical system design method with dual optical path mixing with long mixing distance is proposed. The optical path includes nine lenses, the semi-reverse half lens is placed at the aperture stop, and the double optical path corresponds to different performance LED integrated chips. The optical system has a longitudinal magnification of −1, a curvature of field of 0.5 mm, and a distortion of less than 0.2%, and achieves light mixing of a high uniformity and high color rendering LED.

Keywords: Optical design Double light path LED Uniformity Color rendering
