Prediction of the Action that Polychromatic Light Gives to Circadian Rhythm(<Feature>Indoor Lighting at Night Taking Effect of Light on Circadian Rhythm into Consideration)

Abstract

It has been reported by only the knowledge about the action spectrum for melatonin suppression that prediction of the amount of actions by monochromatic light and polychromatic light cannot fully be performed. Although the hypothesis that an action spectrum has negative sensitivity, and the hypothesis that slope of a dose-response curve changes with the features of spectral distribution have been reported as a reason prediction is not enough, it has not fully been verified yet. It will be necessary for the user to know the condition that the action prediction including a comparison between the monochromatic light and the comparison between the polychromatic light is possible enough.
