| Abstract: | An optical system design method for LED lighting based on edge-ray theory is presented.The two LED uniform illumination systems based on LED lens and reflector respectively are developed to target a specific distance from the surface of the formation of uniform illuminated circular spot with desired size.Two kinds of optical systems are simulated by ray tracing software based on Monte-Carlo method,the results show that the luminous uniformity is better than 85% in the illuminated spot and the system efficie... |
