发布时间：2018-07-25 17:58
【摘要】：为了验证小尺寸光源的不舒适眩光评估模型对LED的适用性,使用两种色温的白光LED产生不舒适眩光,在4种眩光源亮度和4种观察角度下进行实验,并在每种条件下进行deBoer评分。实验结果表明,白光LED的偏心角增大,会增加亮度对比度;白光LED的亮度越大,偏心角越小,则deBoer评分越高,即产生更多的不舒适眩光。对小尺寸光源模型UGRsmall以及位置系数修正模型UGRS1和UGRS2进行实验验证,结果表明模型计算值与主观实验不舒适眩光评分的相关性较高。将UGRS2模型增加优化系数并进行优化得到模型UGRSa,将偏心角加入模型UGRsmall并修正后得到UGRSk,UGRSa和UGRSk均具有更好的性能。
[Abstract]:In order to verify the applicability of the model to LED, two kinds of white light LED with different color temperature were used to produce uncomfortable glare. The experiments were carried out at four different luminance sources and four observation angles. DeBoer score was performed under each condition. The experimental results show that the greater the eccentric angle of white LED is, the greater the brightness contrast is, and the higher the brightness of white light LED is, the smaller the eccentric angle is, the higher the deBoer score is, that is, more uncomfortable glare is produced. The small light source model (UGRsmall) and the position coefficient correction model (UGRS1 and UGRS2) are verified by experiments. The results show that the calculated values of the model are highly correlated with the subjective experimental discomfort glare score. The UGRSA model is obtained by increasing the optimization coefficient and optimizing the UGRS2 model. The eccentricity angle is added to the model UGRsmall and the modified UGRSkK UGRSa and UGRSk have better performance.
