Latest Results on LED Museum Lighting: Colour Quality and Artwork Preservation

Abstract

This paper describes a comprehensive study on museum lighting: one part of the study investigates the damage potential of LED museum lighting by generating composite LED spectra with the help of a mathematical algorithm, while the other part investigates the effects of LED lighting on the appearance of artworks. Spectral optimization of LED light has been carried out by using historical pigment reflectance samples instead of the test colour samples used in the CIE CRI method [CIE 1995], because the reflectance of these historic pigments is significantly different from the reflectance of today's pigments.
