Lighting is a critical component in a museum environment because, together with temperature, relative humidity and pollutants, it is one of the damaging factors able to produce long‐term, cumulative and irreversible photodegradation processes. To correctly preserve artworks, limiting illuminance and exposure is recommended, allowing on one side the preservation of the object, but on the other limiting the display of the object, especially for sensitive materials. The aim of this research was to develop, evaluate and compare a new lighting method for paintings and other cultural materials to improve the experience of the objects whilst reducing the risks from exposure. The idea is based on the use of selective chromatic light where the component of the spectrum absorbed by the materials is removed. This absorption is the principal cause of photodegradation. The proposed lighting system can be obtained by combining different types of projection systems together with filtering using an appropriate light source. Six methods of light projection have been compared for two mock-ups simulating real artworks with high and medium light sensitivity. The efficiency of illumination increased from 30% to 111% compared to standard lighting systems. Light stability tests were additionally performed, finding reduced colour changes compared to traditional lighting systems.

照明是博物馆环境中的关键组成部分，因为它与温度、相对湿度和污染物一起，是能够产生长期、累积和不可逆光降解过程的破坏性因素之一。为了正确保存艺术品，建议限制照度和曝光，一方面允许对象的保存，另一方面限制对象的展示，特别是对于敏感材料。这项研究的目的是开发、评估和比较一种新的绘画和其他文化材料的照明方法，以改善物体的体验，同时降低暴露风险。这个想法是基于选择性色光的使用，其中被材料吸收的光谱成分被去除。这种吸收是光降解的主要原因。所提出的照明系统可以通过将不同类型的投影系统组合在一起并使用适当的光源进行过滤来获得。已经比较了六种光投影方法，用于模拟具有高和中光灵敏度的真实艺术品的两个模型。与标准照明系统相比，照明效率从 30% 提高到 111%。此外还进行了光稳定性测试，发现与传统照明系统相比，颜色变化减少。已经比较了六种光投影方法，用于模拟具有高和中光灵敏度的真实艺术品的两个模型。与标准照明系统相比，照明效率从 30% 提高到 111%。此外还进行了光稳定性测试，发现与传统照明系统相比，颜色变化减少。已经比较了六种光投影方法，用于模拟具有高和中光灵敏度的真实艺术品的两个模型。与标准照明系统相比，照明效率从 30% 提高到 111%。此外还进行了光稳定性测试，发现与传统照明系统相比，颜色变化减少。
