Will Controls Be Key to Circadian Lighting?

By Craig DiLouie

LightingWhile “circadian lighting” varies in definition, it generally refers to design that uses intensity and spectrum of light for a non-visual effect — namely, to support regulation of circadian rhythms. A new study suggests that by enabling intensity and spectral adjustment and optimizing exposure based on time of day, designers and owners can minimize the energy trade-off imposed by associated typically much higher light levels. This would entail use of an advanced lighting control system capable of scheduled dimming and perhaps spectral emission adjustment. Circadian lighting, or biologically effective lighting, is the culmination of decades of research, though as a design practice it is new to the lighting industry. As such, it’s evolving as ongoing research is incorporated. Read More
