Abstract
The lighting system that uses organic EL technology a quality lightfeatures. We design an essential relaxation space with the OEL light. In searching for the relation to the Japanese-style room space, thedevelopment with the temporary housing space it was tried to beassembled. It is important to develop the product that offers a comfortable optical environment from evaluating person's physiology function, and obtaining neither the luminance nor brightness more than is necessary. It was verified by a questionnaire survey by the stage rating method, evaluating the comfort of the space that used organic EL. It is thought that the lighting environment that people can enjoy, is similar to the light of the natural world, but the darkness and soft luminance also will be necessary in the future.
