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.
La présente invention porte sur un système de lumière artificielle utilisé pour moduler le rythme circadien, augmenter la vigilance et influencer les états psychologiques associés à la lumière, tels que la dépression saisonnière. Le système de l'invention comprend une source de lumière verte et/ou rouge et une source de lumière bleue commandées par un ordinateur pour procurer des conditions de lumière prédéterminées. Plus spécifiquement, l'ordinateur est programmé pour que lesdites sources produisent des impulsions de lumière bleue et une lumière rouge continue ou pulsée, ce qui améliore l'efficacité de la lumière bleue, réduit le risque de lumière bleue et prévient l'effet stroboscopique.
