| Outline of Final Research Achievements |
The direct lighting is adopted in many buildings. It is convenient to get a certain illuminance, but is dazzling to catch a lump in a view. On the other hand, the indirect lighting is good for visual environment, but is disadvantage to get same illuminance. In this study, some light dimming experiments in the class room were done. As the results, the illuminance is not high proportion to the easiness in seeing. By the other results of experiments on the pupil's shrinkage response under various positions and brightness of lamps, the shrinkage motion of the pupil occurred when the the lump is in a certain field of the view and it was remarkable in case of a high brightness of a lump. And according to the questionnaire that was done simultaneously, there is the definite correlation between the pupil’s shrinkage motion and the feeling of dazzling. Based on such results, I propose new lighting design method taking account of the luminance distribution as the criteria.
