Effect of Colour Rendering for University Campus Landscape Lighting at Night in a Snowy Region
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 1
Abstract
The importance of the landscape lighting of urban nightscapes is increasing with the urban lifestyle for a 24-hour-life. In addition, the feature of landscape lighting has changed from emphasis on the lighting design for the conventional purpose of safety and the degree of brightness to a lighting plan which matches with the view in the region as well as in consideration of psychological comfort. By the way, snow is sometimes a fearful thing which brings about a major disaster, but at the same time, it has beauty appealing to people’s heart and wonderful attraction. Accordingly, what is sought in a design for landscape lighting in such an environment must be an atmosphere in the space such as an “element which has an effect to alleviate the coldness of snow” or an “element that enables the beauty of snow to be enjoyed”. In this study, we tried to evaluate the effect which the difference in a hue of the light source in landscape lighting gives to urban scenery perception in a snowy region quantitatively and at the same time to examine and consider about “how landscape lighting should be in a snowy region”. We selected six kinds of typical urban landscape lighting as samples. We took photographs of these nightscapes. We made another samples which landscape lighting colour changed to “red”, “orange”, “yellow”, “white” or “skyblue” using computer, and presented to subjects. We applied SD technique to the evaluation for these samples. Also, we analyzed the difference between three samples, using factor analysis. From the results, we found that the landscape lighting of “red” and "orange" provided an active impression to the urban nightscape. On the other hand, the landscape lighting of “skyblue” provided a beautiful impression to the urban nightscape.
