Museum lighting environment: Designing a perception zone map and emotional response models

This paper describes two experiments that were designed to investigate the museum lighting environment in terms of correlated colour temperature and illuminance. The results are reported as visual perceptions and perception zone maps. Experiment 1 was conducted to investigate the impact of the illumination conditions on visual perceptions in a light cabinet. Experiment 2 was the same as Experiment 1, except that it was performed in a museum. The rating scores were combined to establish the perception zone maps on a correlated colour temperature–illuminance plane. Furthermore, two emotional response models, named the visibility model and the warmth model, suitable for museum indoor lighting in small- and large-scale spaces were established. The analytical results indicated that the pleasant zone found in this study partially agrees with Kruithof's rule.
