Outline of Final Research Achievements

Migraineurs don’t prefer the conditions of 5500K as compared with non-migraineurs when the
condition is high illuminance. In addition, impression of migraineurs and that of non-migraineurs under the lighting condition is different. The evaluation of preference is better under the lighting including the component 585-636nm than that of 517-560nm. Also, the understandability of the cooking degree is the highest under the lighting conditions of 5000K and Duv=0.00. However, the apparent cooking degree depends on the spectral power distribution of lights. Moreover, when the lighting changes from low CCT to high CCT, the values of Et=∞ almost become 0. Also, the values of Et=∞ when changing from high CCT to low CCT are larger than that when changing from high to low CCT.
