Abstract
The present invention relates to an artificial light system for modulating circadian rhythms, increasing vigilance and influencing light-associated psychological conditions such as seasonal affective disorder. The system of the invention comprises a source of a green and/or red light and a source of blue light both light sources being controlled by a computer to provide predetermined light conditions. More specifically, the computer is programmed to provide pulses of blue light and continuous or pulsed red light, to enhance the efficacy of blue light, reduce blue-light hazard and avoid stroboscopic effect.
