摘　　要：基于人眼主观光亮度的理论,本文提出了一种结合菲涅尔挤出透镜、反光片及扩散板的黑板灯照明灯具设计。通过软件进行光学仿真及优化,并制作实际样品测试。所研发出的新型LED黑板灯实测平均照度达到726.6 lx,照度均匀度达到0.857,同时降低使用者的不舒适眩光感受,实现适配黑板使用情况的直视不刺眼的良好照明体验。Based on the theory of subjective brightness of human eyes,this paper proposes a blackboard lamp lighting design that combines Fresnel extrusion lens,reflector and diffuser.The optical simulation and optimization are carried out by software,and the actual sample test is made.The measured average illumination of the new LED blackboard lamp developed reaches 726.6 lx,and the illumination uniformity reaches 0.857.At the same time,it reduces the user's uncomfortable glare feeling and realizes a good lighting experience that is suitable for the use of the blackboard.
