PROPOSAL OF DISTRIBUTED MULTIPLE-LIGHT ARRANGEMENT USING SMALL HIGH-EFFICIENCY LAMPS AND EVALUATION EXPERIMENT IN THE LIVING AND DINING ROOMS : Research on the improvement of lighting quality and energy conservation by distributed multiple-light arrangement in the residential building Part 1

Abstract

The most popular lighting arrangement in Japanese housing has been one-lamp-per-room. This arrangement is excellent in producing uniform brightness, but it is not suitable for providing variations in brightness needed when occupants are engaged in various activities or for producing the desired atmosphere in the room. Use of multiple lamps has been proposed but has not been widely adopted for a lot of electricity. Considering the reason of the situation described above, in this study, we proposed a reasonable concept for distributed multiple-light arrangement for an improved residential environment and for energy conservation. We carried out an evaluation experiment based on the concept in the actual living and dining rooms.
