白光LED对中国传统书画色彩的影响
Influence of WLED on color of Chinese traditional calligraphy and painting

为得到低色温高显色性白光LED光谱对中国传统书画色彩的量化影响规律，论证白光LED在书画展陈照明中的实际适用性，基于满足书画照明标准的RYGB型白光LED光源照射书画模型试件的实验方法，周期性测量试件色彩参数，进而绘制色坐标和亮度值随时间周期性变化曲线图，通过分析色坐标在CIE 1931色度图上的变化情况以及亮度衰变曲线，得到此类白光LED对书画色相、饱和度、明度的量化影响规律，提出RYGB型白光LED在书画展陈照明中的应用依据。
In order to quantify the WLED's impact on color of Chinese traditional calligraphy and painting, and explore the practical applicability of using WLED as display lighting, an experiment was carried out on the RYGB type of WLED irradiated models of calligraphy and painting. And the color parameters was tested periodically to make curve charts of color coordinate and luminance over time. The impact of the WLED on hue, saturation, brightness was quantified based on the carve to provide evidence of application of WLED.
