Abstract
In the art museum, lighting plays a crucial role in visitors’ understanding and appreciation of exhibits. This paper mainly explores the influence of different lighting mode (general lighting, accent lighting, and mixed lighting) and correlated color temperature (CCTs) (4000 K and 2700 K) changes on the observers’ psychology to find the best lighting environment. Based on the simulation carried out at the National Museum of Western Art in Japan, we made six diverse lighting designs. 31 observers were invited to evaluate each scheme, and the results of subjective evaluation were analyzed by means of one-way analysis of variance and the paired sample T-test. According to the results of data analysis, suggestions can be given for art gallery lighting design. It is not recommended to use general lighting alone in art museums, and it is better to use mixed lighting. When the CCT is 4000 K, only accent lighting can be used. When the CCT is 2700 K, the mixed lighting effect is better.
Highlights
Most of them focused on the influence of changing illuminance and correlated color temperature (CCT) on visual effect in order to determine the best lighting arrangement
The observer makes a subjective evaluation of the current lighting environment in the art museum, and the observer fills in the corresponding score according to the questionnaire
We found that in this experiment, the average score of 31 participants on the beauty/ugliness of the art museum was not affected by the CCT, with an average score of 3.60
Summary
Museum lighting is uniquely challenging. The lighting must reveal the visual detail and emotional power of the art work to the viewers and protect and preserve its content and integrity for the future. Contemporary approaches to museum lighting are followed to strike an appropriate balance between two main topics: minimizing the potential damaging effect of light on artworks and obtaining the best visual impression through light.. The result demonstrated that CCT was the main factor affecting the painting’s appearance and the observers’ overall preference for the lighting arrangements, while the overall hue content of the painting and the background lightness had a minor influence. They found that the perceived brightness increases along with the CCT.. Kruithof used a number of conventional light sources such as incandescent lamps, daylight originating from a window, and fluorescent lamps He proposed a method to achieve the “pleasure effect” based on the correlation diagram of CCT and illuminance in interior lighting design. Kruithof’s rule shows that specific zones at high (low) CCT and high (low) illuminance make observers feel pleased. some research results did not fully comply with this rule
