摘　　要：北京、陕西两个地区的古建筑保存较为完好且有代表性,因此我们对这两个地区的古建筑照明进行了实地调研。在照明设计中,古建筑彩画照明是展现古建筑古韵的最佳承载者,通过研究发现彩画照明效果主要影响因素为光源功率和色温。本文以D65为标准参照光源,以3000 K、4000 K、5000 K、6000 K的4 W、9 W、13 W、20 W LED为实验用灯具对古建筑修复工艺制作的彩画试块,分别进行照射实验,测量色彩偏移指标ΔE,并在同等实验条件下进行主观测试实验,在测定了测试试块的客观色差值和主观感受评价后,通过直线内插法计算6种常用彩画颜色在常用的4种色温(3000 K、4000 K、5000 K、6000 K)下的色彩偏移阈值及其对应的最大功率值,汇总出适用于各颜色彩画照明的LED光源参数,为古建筑彩画照明设计提供参考。Beijing and Shaanxi province are one of the most well-preserved and representative regions in terms of Chinese ancient architecture,so we did in-depth field research on the lighting of the ancient buildings in these two regions.In terms of lighting design,the illumination of ancient architectural color paintings is the best carrier to demonstrate the classical grace of ancient architecture.Through research,it is found that the power of light source and color temperature arethe main influencing factors of the illumination effect of color paintings.The purpose of this research is to study the relationship between the maximum subjective perception deviationof ancient color paintings at night andthe power of light source and color temperature,so as to provide guidance for the parameter selection of lamps and lanterns for lighting design of ancient architecture.In this paper,D65 as the standard reference light source,four kinds of LED lights,power at 3000 K,4000 K,5000 K and 6000 K and correspondinglycolor temperature at 4 W、9 W、13 W、20 W,are chosen respectively to be experimental illuminants for thetest piece of color painting made through restoration technology of ancient buildings.Radiation experiments were carried out to measure the color deviation index-ΔE.After measuring the objective chromatism and subjective perception evaluation of the test piece,six common drawing colors used in ancient architectural color painting were calculated with themethod of linear interpolation.Then through calculation of the color shift threshold and the corresponding maximum power value under four commonly used color temperature conditions(3000 K,4000 K,5000 K,6000 K respectively),the parameters of LED light source suitable for each color in color painting illumination are summarized,which can provide references for ancient lighting design.
