摘　　要：根据对投光照明应用场合的具体分析,基于绿色照明的理念和要求,本文给出了投光照明灯具光学设计时光源和器件材料的选择以及灯具的配光设计要求:首先选择短弧、高光通、高显色性和高流明维持率的传统光源以及新兴的高效LED照明光源;其次采用模块化模式设计全方位组合不同反射功能的反光罩,遮光罩以及折射透镜,控制光的投射方向和光束形状,降低灯具的溢出及偏射光能和人工照明形成的天空杂散光,提高投光照明的视觉舒适度,控制光污染;另外还可以改善投光照明灯具反射材料和透镜材料的光学性能,提高灯具光输出率,节省能源,降低照明成本。In this paper,according to the specific analysis of flood lighting applications,green lighting ideals and requirements from CIE should be considered abundantly during designing optical system of flood luminaires,Firstly,traditional light source with short arc,high lumen out and high color render index（ CRI）,or new LED light source are used,secondly,the optical reflector combined with different functional optical modules,the refractor and optical lens are used to control the light beam shape and light direction to decrease the spill light and stray light from flood luminaires in the sky. visual comfort is improved and light pollution is down,finally,lumen output rate of flood luminaires is improved by means of prompting material performance of reflector and optical lens,at last,energy is saved and lighting cost is reduced.
