【摘要】 本研究评估了CIE标准照明体D50和A模拟光源的照明品质,其中模拟光源是基于多通道LED光源以及传统荧光灯和钨灯。为了评估四种模拟光源可感知的照明品质的不同方面:色貌和色差,本研究展开了两个心理物理学实验。十位拥有正常色觉的观察者参加了实验,对30对同色异谱色样进行评定。每对色样都包括了一块颜色恒定的色样和颜色不恒定的色样。视觉结果被用于分析验证四种模拟光源的表现。研究发现,色差评估的结果清楚地表明了LED D50模拟光源的表现显著优于传统的荧光灯。更多还原

【Abstract】 This study investigated the perceived colour quality of CIE D50 and A simulators based on multi-channel LED sources and conventional fluorescent and tungsten lamps.Two psychophysical experiments were carried out to evaluate different aspects of perceived colour quality of the four simulators:colour appearance and colour difference.Ten observers with normal colour vision participated to assess thirty metameric pairs,which were consisted of colour constant and inconstant samples.The visual results were analyzed to indicate the performance of the four simulators.It was found that the colour difference results clearly showed that LED D50 simulator significantly outperformed the conventional fluorescent source.更多还原
