An anti-glare luminaire design is proposed to reduce the effect of glare and the multi-shadow while preserving high optical efficiency, high illumination uniformity and low unified glare rating (UGR). Comparison to the traditional direct light emitting diode (LED) luminaire in optical simulations showed an enhancement of the illumination uniformity from 64.9% to 80.0%. The optical efficiency was 79.5%, and the UGR value was controlled under 18.8. For the actual measurement, the finished product had an illumination uniformity of 77.0%, optical efficiency of 76.0%, UGR value of 19.0, and efficacy of 81.4 lm/w. Through this design, the lighting performance was greatly enhanced.
提出了一种防眩光灯具设计，以减少眩光和多重阴影的影响，同时保持高光学效率、高照明均匀度和低统一眩光值（UGR）。在光学模拟中与传统的直接发光二极管（LED）灯具相比，照明均匀度从64.9%提高到了80.0%。光学效率为79.5%，UGR值控制在18.8以下。实际测量时，成品的照明均匀度为77.0%，光学效率为76.0%，UGR值为19.0，发光效率为81.4 lm/w。通过这种设计，照明性能得到了极大提高。
