Abstract The need to achieve energy efficiency standards in the lighting systems of buildings makes it necessary to optimize all aspects of them. Here, the development of a light projection system that achieves this goal by studying and modifying the spectral output, compared to conventional illumination, is described. A lighting system that estimates the reflectance characteristics of artwork and emits optimized lighting can reduce light absorption. A damage-minimizing point-by-point light projection system is developed using an optimization algorithm, to improve the appearance of the surfaces of artworks whose color has faded. In this case, a simulation of an aged oil painting was made by manipulating the original photograph, which was printed and to which the proposed system was applied. The results show that, when the aged printed image is illuminated with the optimized light source, it appears indistinguishable from the non-aged oil painting.

用于建筑物的光投射系统的能源优化，几乎可以还原艺术品

摘要建筑物照明系统需要达到能效标准，因此有必要对其各个方面进行优化。这里，描述了与常规照明相比通过研究和修改光谱输出来实现该目标的光投影系统的开发。估计艺术品的反射特性并发出优化照明的照明系统可以减少光吸收。使用优化算法开发了一种损伤最小的逐点投影系统，以改善颜色褪色的艺术品表面的外观。在这种情况下，通过处理原始照片进行模拟，以模拟老化的油画，该原始照片被打印并应用了所建议的系统。结果表明，
