Abstract

The living room is basically an important space in the residence because we stay in the space for a long time, doing various deeds. Accordingly, in the living room the lighting method is necessary which improves visual performance and produces comfort and pleasant atmosphere. In order to develop the new lighting method, authors quantitatively cleared the required atmosphere in the living room and next made quantitative analysis of relations between lighting condition and atmosphere. In this report, at first, deeds in the living room were classified into four living scenes, being unbending, pleasure, dinner and party.<BR>In the second place, required atmospheres corresponding to four living scenes were quantitatively cleared by factor analysis in the semantic differential method. At last, for the development of the new lighting method producing the required atmosphere in the living room, experiments containing transition of atmosphere caused by lighting condition were made and relations between lighting condition and atmospheres corresponding to four living scenes were quantitatively made clear. As a result, it was made clear that the lighting method using plural lighting fittings and changing the lighting method corresponding to the living scene were very effective for making the improved atmosphere.
