本研究探讨了博物馆绘画观赏的主要视觉感受和最佳LED照明参数。采用分类评判法对不同LED光源下的油画和水粉画进行评价。研究发现，“可见性”和“温暖性”是观看绘画时的主要感受。结果表明，在3500 K左右的相关色温、目标与黑体轨迹的负偏差以及较高的显色指数下，可以获得满意的结果。本文还探讨了基于色彩保真度的显色指数和基于色彩偏好的显色指数在博物馆应用中的区别。
This study investigated the main visual perceptions and the optimal LED lighting parameters for viewing museum paintings. Oil and gouache paintings seen under different LED illuminants were assessed using the categorical judgement method. It was found that ‘visibility’ and ‘warmth’ are the main perceptions for viewing paintings. The results showed that a correlated colour temperature around 3500 K, a negative deviation of the target from the blackbody locus and a high colour rendering index can achieve satisfactory results. The difference between colour fidelity-based colour rendering indices and colour preference-based colour rendering indices for a museum application was also explored.
