【摘要】：为得到构成白光LED光谱的主要单色光对中国传统淡彩绘画色彩的影响规律,确定不同波长单色光对绘画色彩的量化损伤程度,进而根据研究结果得到最低损伤白光LED的光谱功率分布,以构成白光LED光谱的4种主要单色光作为实验光源,分组照射中国传统淡彩绘画模型试件。在每个照射周期后,对试件的色彩参数进行检测,根据检测数据绘制主波长、兴奋纯度、亮度3个参数随总曝光量积累的衰变曲线,基于曲线分析得到各种淡彩绘画颜料在光照下的色彩衰变规律,并根据实验数据计算得到4种单色光对绘画色彩主波长的影响关系为482 nm∶510 nm∶583 nm∶650 nm=8 147∶9 067∶9 772∶9 121;对兴奋纯度的影响关系为482 nm∶510 nm∶583 nm∶650 nm=89 446∶85 250∶76 895∶69 229;对亮度的影响关系为482 nm∶510 nm∶583 nm∶650 nm=137∶238∶190∶177。
[Abstract]:In order to obtain the influence of the main monochromatic light which constitutes the white LED spectrum on the color of Chinese traditional light color painting, the quantitative damage degree of different wavelength monochromatic light to the painting color is determined. According to the research results, the spectral power distribution of the least damaged white light LED was obtained. The four main monochromatic light sources of the white light LED spectrum were used as experimental light sources to illuminate the Chinese traditional light color painting model samples in groups. After each irradiation period, the color parameters of the sample were detected, and the decay curves of the main wavelength, exciting purity and brightness accumulated with the total exposure were plotted according to the detection data. Based on the curve analysis, we can get the color decay law of various light color painting pigments under light. According to the experimental data, the influence of four monochromatic light on the main wavelength of painting color is 482 nm:510 nm:583 nm:650 nm=8 147: 9 067: 9 772: 9 121, and the relation on the exciting purity is 482 nm:510 nm:583 nm. : 650 nm=89 446: 85 250: 76 895: 69 229; effect on brightness is 482 nm:510 nm:583 nm:650 nm=137:238:190:177.
