| Summary: | 博士 === 國立臺灣科技大學 === 應用科技研究所 === 106 === Several guidelines should be considered when designing museum lighting, including the artist’s intention, art conservation, energy efficiency, and viewing experience. This study conducted two types of experiments for the applications of LEDs for museum lighting. First, we conducted psychophysical assessment to observe the impact of correlated color temperatures (CCTs) and illuminance levels of test light sources. Secondly, accelerating experiment was designed to execute the light damaging evaluation.
Experiment 1 was conducted to investigate the impact of the lighting conditions on visual perceptions under different illumination designs according to the combination of CCT and illuminance level. Thus, the traditional Kruithof’s rule was further investigated for the application of museum indoor lighting in small- and large-scale spaces. Besides. Experiment 2 identified that whether the CIE157:2004 guideline based on threshold effective radiant exposure (Hs,dm) can be applied to the actual aging test of UV-filtered light sources. The color fading model was proposed in this study and it can be well applied to predict the color differences of the three kinds of contemporary photographic materials (Chromogenic print, Cibachrome, inkjet print) for short- or long-term exhibition when using LEDs. This study also provided a revised light dosage classification of modern photographic materials for museums. Moreover, the verification studies can be used as a conceptual reference for assessing the damage potential of other art materials under the tunable multi-LED system in the future.
