Artificial Lighting in Museums: an Interdisciplinary Approach towards Improving Museum Visitors' Emotive Experience

Based on an investigation by Liaoning Provincial Museum, the lighting environment brought by artificial lighting design was used to test visitors' emotive response levels. The investigation concentrated on visitors' emotive experience. Forty visitors were invited to participate in the evaluation of exhibits through simulation experiments. Keywords were recorded throughout the exhibits to be evaluated in order to assess the subjective factors that have the greatest impact on the emotive experience, including comfort, texture clarity, and colour (authenticity). The colour rendering index in the optical correlation properties was discussed in detail, and the color temperature was briefly described. The corresponding color table data (color table map) was obtained through the use of the theoretical formula of R, G, and B color signals and the color tone formula in Experiment 1 (building color vision model). Taking 2950 K tricolor fluorescent lamps in Liaoning Provincial Museum as an example, and the corresponding Kendall level correlation coefficients Ra, Qa, FCI were obtained via CIE colour rendering sample measurement method and also 2950 K fluorescent lamp spectral energy data as the research object in Experiment 2. The weight W was discussed in combination with the visitors' questionnaires to characterize the color fidelity evaluation of the light source. Finally, the characteristics and design concept of artificial lighting were analyzed and summarized, so as to come up with recommendations for improving the emotive response level to museum lighting. This research will have far-reaching significance regarding design of artificial lighting in museums.
