MUSEUM LIGHTING ENVIRONMENT: BUILD UP PERCEPTION ZONE MAPS ON LED ILLUMINATION

摘要

Two experiments were conducted to collect the visual appearance data under different illumination conditions according to correlated color temperature (CCT) and illuminance level. Experiment 1 was carried out to investigate the impact of LED illumination conditions on visual perceptions in a viewing cabinet. Experiment 2 is the same as Experiment 1 except that it was performed in a real museum. It was found that the results between the two experiments were similar, indicating little difference between viewing environment on visual perceptions. The data were combined to establish the perception zone maps in CCT and illuminance plane.
