Abstract
Systems tune, control, or remediate the intrinsic Circadian clock. A light controller sets spectral distribution, intensity of a bioactive spectral band to shift or entrain circadian response to enhance performance and/or synchronize with local or expected conditions. The systems enhance performance under conditions that might be changing, disrupted, or otherwise present an irregular phase or unnatural change in the subject's circadian status, for example, due to geographically discontinuous activity or spectrally deficient workplace illumination, or due to divergent individual sleep/wake behaviors of subjects in a structured group activity. An illumination recipe that compensates for the deficiency of lighting or of participant sleep or behavior patterns, or age- or disease-related changes, to evoke, shift, or align circadian response and improve behaviors such as classroom alertness, relaxation, excitability, attention, or focus. Systems may receive sensed light values and automatically apply high- and/or low-CER illumination to effect the intended circadian phase.
