【摘要】：為了驗(yàn)證小尺寸光源的不舒適眩光評估模型對LED的適用性,使用兩種色溫的白光LED產(chǎn)生不舒適眩光,在4種眩光源亮度和4種觀察角度下進(jìn)行實(shí)驗(yàn),并在每種條件下進(jìn)行deBoer評分。實(shí)驗(yàn)結(jié)果表明,白光LED的偏心角增大,會(huì)增加亮度對比度;白光LED的亮度越大,偏心角越小,則deBoer評分越高,即產(chǎn)生更多的不舒適眩光。對小尺寸光源模型UGRsmall以及位置系數(shù)修正模型UGRS1和UGRS2進(jìn)行實(shí)驗(yàn)驗(yàn)證,結(jié)果表明模型計(jì)算值與主觀實(shí)驗(yàn)不舒適眩光評分的相關(guān)性較高。將UGRS2模型增加優(yōu)化系數(shù)并進(jìn)行優(yōu)化得到模型UGRSa,將偏心角加入模型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.
