The impact of spectral characteristics of light sources on the subjective perception of historical objects
Original language description
The nighttime illumination of historic buildings affects their aesthetic perception and environmental impact. White light, imitating daylight, is often used for architectural lighting today. In order to improve the visibility of the object and details, it changes the image of historic buildings, characterized by soft night lighting. Recent findings also show the negative impact of light on nocturnal ecosystems. This paper discusses observer acceptance of various modern LED light sources with different spectral composition. In the laboratory settings, subjective perceptions were gathered through questionnaires assessing lighting quality and spatial impression. Data suggest that eye adaptation to light and the immediate lighting conditions has a strong effect on the subjective evaluation. Further, the ability to differentiate and correctly describe differences between the lighting was limited if lights were not observed in one scene. In general, good acceptance of warm light has been found. Our findings confirm that selection of light source spectral properties can provide sustainable solution that preserve historical heritage and minimize negative impacts on biodiversity and light pollution.
