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 studyingand modifying the spectral output, compared to conventional illumination, is described. A lighting system thatestimates the reflectance characteristics of artwork and emits optimized lighting can reduce light absorption. Adamage-minimizing point-by-point light projection system is developed using an optimization algorithm, toimprove the appearance of the surfaces of artworks whose color has faded. In this case, a simulation of an aged oilpainting was made by manipulating the original photograph, which was printed and to which the proposedsystem was applied. The results show that, when the aged printed image is illuminated with the optimized lightsource, it appears indistinguishable from the non-aged oil painting.
