摘　　要：在LED逐步替代传统光源的时代,多数人还存在一个误区“显色性最高等于颜色呈现最好”。因此,色彩丰富的古建通常会选用显色指数80以上3000~4000 K光色来表现。然而,对于效果来说,随着功率不同、被照面的亮度不同等客观因素制约,用单色光很难还原载体日光下饱和度很高的固有色。这时,LED灯具灵活定制的优势又在众多精品工程案例中显现出来。本文通过几个精品古建照明项目,针对适合表现古建惯有的红墙、绿瓦及金色构件的混合光色LED灯具,来研究古建夜景照明的色彩呈现需要。In the era when LEDs are gradually replacing traditional light sources,there is still a common misconception that“the highest color rendering index(CRI)equals the best color representation”.As a result,colorful historical architectures often opts for light sources with a CRI of over 80 and a color temperature of 3000~4000 K to showcase their vibrant colors.However,in practice,due to various objective factors such as different power levels and varying brightness levels,it is difficult to accurately reproduce the high saturation inherent colors of these structures using monochromatic light,In such cases,the advantages of customizing LED fixtures become evident,as demonstrated in several high-quality historical architecture lighting projects.This article explores the color representation requirements for nightscape lighting of historical architecture by analyzing a few high-quality projects,focusing on the use of mixed-color LED fixtures suitable for showcasing the red walls,green tiles,and golden components commonly found in historical buildings.
