Abstract:	摘要： Using the precise mid field angular distribution model of the LED light source and the optical scattering surface property of the Harvey BSDF scattering model, we perform optical simulation to develop and design a novel solid plastic optical lens with freeform inner surface to achieve the optical performance of 89.89% light energy transmission optics for the sake of energy saving reason. The 70 degrees angular light distribution pattern defined at full width half maximum (FWHM) light energy level is performed and the optical utilization factor (OUF) of 51.8% is obtained within -45 degrees and 45 degrees range in the areas of interest with glare reduced for the down light illumination. 其他題名： Opt Express 出版者： United States 出版日期： 2015-06-29 出處： Optics express, 2015-06, Vol.23 (13), p.16715-16722 資源來源： Optica Publishing Group Journals 識別號： ISSN: 1094-4087 識別號： EISSN: 1094-4087 識別號： DOI: 10.1364/OE.23.016715 識別號： PMID: 26191683
