Recently, researchers from the Information Photonics Research Laboratory of the Xi'an Institute of Optics and Fine Mechanics of the Chinese Academy of Sciences have designed a lens for achieving efficient LED collimation illumination, which can focus 80% of the LED light into a cylinder with a radius of 5 meters. 200 meters of road surface. As the fourth generation of illumination source, LED is the key to achieve efficient light output and collimated illumination. The authoritative journal of the international optoelectronic field believes that researchers use a simple and fast method to design two non-imaging LED collimating lenses, which is completely different from the complex iterative software design method commonly used in existing LED optical design.
