摘要

对不同光谱分布的发光二极管(LED)引起的不舒适眩光进行了研究。设计开发了红/绿/蓝/白(R/G/B/W)4色LED光源模块,研究了该模块在3种不同背景亮度下的眩光效应,并在每种条件下进行了7等级量表主观评价。实验结果表明:在3种不同背景亮度下,R/G/B/W 4色LED光源产生了不同程度的眩光。在同一背景亮度下,LED亮度越大,主观实验评分越高,即产生更多的不舒适眩光。同时研究发现,B-LED光源不舒适眩光最强,W-LED光源不舒适眩光最弱,验证了统一眩光指数(RUGR)模型对该4色LED光源的适用性。B-LED光源RUGR计算值与主观实验不舒适眩光评分的相关性最差,W-LED光源在背景亮度Lb=19.967 cd·m -2时其相关性最好(R2=0.951)。

Abstract

In this study, the discomfort glare caused by light emitting diode (LED) modules with different spectral power distributions is investigated. Further, red/green/blue/white (R/G/B/W) four-color LED source modules are designed and developed. The glare effect of the modules is determined for three different background luminances. Subject assessment of each condition is provided according to a seven-level scale. Results show that different glare effects are caused by the R/G/B/W four-color LED sources for three different background luminance. A high subjective rating score is obtained at a large luminance of the four modules within the same background luminance, causing more discomfort glare. Simultaneously, the largest glare is caused by B-LED source, whereas the smallest glare is caused by W-LED source in those modules. The unified glare rating (RUGR) model is used to experimentally verify the applicability of four-color LED source modules. Results show that the correlation between calculated value of RUGR and subjective discomfort glare rating score of the B-LED source is the worst, whereas the W-LED source has the best correlation (R2=0.951) when the background luminance Lb is 19.967 cd·m -2.
