摘要(Abstract):

彩色绘画作品常用来研究博物馆LED照明的显色质量。近几年来,我们设计执行了一系列相关的心理物理实验,对照度、色温、显色性(色彩保真度)以及色域大小和形状不同的LED照明进行了研究,数据结果与国际其他研究团队相关成果进行了比较。博物馆照明的最适宜色温可总结为3 000 K至4 000 K之间。照明的色彩保真度和色域都对画作的视觉效果有显著的影响。光谱可调的照明方式成为趋势。
Colorful paintings were widely used to study the colour quality of museum LED lightings. Several psychophysical experiments were conducted in recent years,to study the colour appearance and the observer preference on paintings under LED lightings with various illuminance levels,colour temperatures,colour fidelity levels,and sizes and shapes of colour gamut. The results were compared with other researchers' worldwide. The optimal colour temperature for museum lightings was found to be very culture dependent. In Asia,it was found between 3 000 K and 4 000 K. The colour fidelity and the colour gamut of LED lightings have significant effect on the visual perception on painting. It all points toward a spectrum tunable lighting system for illuminating fine art paintings.
