摘要: 我们提出一个具有高效率的直下式LED抗眩灯具的设计并且制作出成品验证,这个抗眩灯具的设计主要用来降低LED所造成的强烈眩光及叠影的效应并且它有着高照度均匀,还有高光效率和能源效率。在模拟验证过程,与传统相比照度均匀度从64.9%提升到80.0%,UGR控制在18.8,并拥有79.5%的高光学效率;在实际成品量测下,照度均匀度可达77.0%,UGR控制在19.0,光学效率在76.0%,且拥有81.4(lm/w)的高能源效率。
An anti-glare luminaire design is proposed that will reduce the effect of glare and the multi-shadow effect 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. Based on the simulation design, the finished product would have 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.
