中国画陈列室的视觉环境研究

光辐射对于中国画可以产生严重的危害,为了保存这些艺术珍品,应尽可能地降低展品上的照度,但是给人观赏又不能让画幅和视觉环境显得昏暗或模糊不清。作者进行了一系列主观评价实验,应用语意差别量表和因子分析,找出了中国画陈列的视觉环境的最佳照明条件。结论为: 1.画幅上的最佳照度为50lx,范围为30-100lx。陈列室的空间光分布要求平均柱面照度/画幅照度((?)/E)比为0.15,范围为0.12—0.20。画幅和环境照明建议采用白炽灯作为光源。2.当使用荧光灯时,画幅照度和平均柱面照度/画幅照度比宜采用较大值。

The Research of the Visual Environment for the Exhibition of Chinese Paintings

Chinse paintings can be seriously damaged by the light radiation. Owing to theconservation of the items on display, the illuminance on these items should be kept aslow as possible, but the picture and visual environment must not be dim and inadequate. The writers have conducted a series of experiments of subjective assessment byusing the technique of semantic differential scale and factor analysis. They find outthe preferred lighting conditions of the visual environment for the exhibition ofChinese paintings. The results are: 1. The optimum illuminance on the picture is 50 lux, and the range is 30-100lux. The mean cylindrical illuminance/picture illuminance ratio (an index forthe light distribution within the space of exhibition area) is 0.15, and the range is0.12-0.20. The incandescent lamp is recommended as the light source for the display andambient lighting of the exhibition of Chinese paintings. 2. When fluorescent lamp used as the light source, the illuminance and themean cylindrical illuminance/picture illuminance ratio should be higher than theincandescent lamp.
