Light source for modulation of circadian rhythms

摘要

A light source is described that can be used to adjust or modulate human circadian rhythms and other photo-dependent body mechanisms. The light produces light containing spectral components having wavelengths distributed throughout the visible spectrum so as to be perceived by the human eye to be substantially white light. The energy of the light emitted by the source within an anomalous waveband around a wavelength of 460nm differs significantly from the energy emitted by the source in any other waveband of equal width to enhance or suppress the modulation by the light source of human circadian rhythms.
