چکیده انگلیسی
Exposing eyes to glare for a long time can make people feel nervous, tired, and uncomfortable. Therefore, achieving high lighting quality and reducing glare of lighting fixtures are objectives worth pursuing. Because most light-emitting diode (LED) panel lights have Lambertian distribution, resulting in excess light in the direct glare area, they have increased unified glare ratings (UGRs). Therefore, in this study, we developed a nondiffuse and microperiodical optical film design for low-glare LED panel lighting. The simulation results revealed that a narrow-angle distribution can provide the optimal average illuminance of 405â¯lx, illuminance uniformity of 0.45 with a top angle of 110°, and UGR of 14, whereas a batwing distribution can provide the optimal average illuminance of 347â¯lx, illuminance uniformity of 0.5 with a top angle of 110°, and UGR of 20. In addition, the optical film of the batwing distribution with a single layer can effectively reduce glare, and illuminance uniformity can be realized at a top angle of 105°.
