博物馆的照明必须使用适合保存被照明物体颜色的光源。本文研究了长时间暴露在博物馆常用的三种光源下对中国传统重彩画常用的五种颜料的色度的影响。这三种光源分别是带有红外滤光片的卤钨灯、金属卤化物灯和RYGB型LED。在1152小时的曝光时间内，定期测量颜料的色度。这些数据用于揭示发生的色度偏移，从而揭示每个典型光源的相对效果。在所测量的三种光源中，RYGB型LED平均具有最小的色度偏移。这些结果为中国传统重彩画照明的相关研究提供了数据库，也为博物馆照明设计中光源的选择提供了更普遍的参考。
Museum lighting must use a light source suitable for preserving the colours of the objects being lit. This paper examines how prolonged exposure to three light sources typically used in museums affect the chromaticity of five pigments commonly used in Chinese traditional heavy colour painting. The three light sources were tungsten halogen with an infrared filter, metal halide and an RYGB-type LED. The chromaticities of the pigments were measured at regular intervals over 1152 hours of exposure. These data were used to reveal the chromaticity shifts occurring and hence the relative effect of each typical light source. Of the three light sources measured, the RYGB-type LED had the least chromaticity shift, on average. These results provide a database for related research on Chinese traditional heavy colour painting illumination and provide a more general reference for the choice of light source in the design of museum lighting.
