| Outline of Final Research Achievements |
Light acts on the human circadian clock, and has a great influence not only on sleep/awake rhythms but also on maintaining homeostasis throughout the body. Light during the nighttime causes an undesired phase shift internal circadian clock and at the same time causing enormous loss of electric power. On the other hand, there are few studies that use knowledge obtained from basic research on physiological responses to the photic environment to improve lifestyle such as sleep/awake rhythms.
Therefore, in this research, we and aimed to develop light environment control technology utilizing visual physiological response characteristics in order to adjust the body clock, achieve a comfortable healthy living environment and suppress energy consumption. As a result, we developed a light control method that makes it possible to dim the light without being conscious of variation of light intensity.
