Title
(EN) LIGHT SOURCE FOR MAINTAINING CIRCADIAN METRICS WHILE ALLOWING FLEXIBILITY IN CHANGING INTENSITY AND COLOR TEMPERATURE
(FR) SOURCE DE LUMIÈRE DE MAINTIEN DE MESURES CIRCADIENNES TOUT EN PERMETTANT UNE FLEXIBILITÉ DE MODIFICATION D'INTENSITÉ ET DE TEMPÉRATURE DE COULEUR
Abstract
(EN)
Methods and systems as described herein may be used for independently controlling the color temperature, intensity, and/or circadian response (CR) of one or more light sources (e.g., discrete-spectrum light sources) to adjust one or more color temperature, intensity, and circadian metrics in a space. For example, a light fixture may have four controllable light sources, a warm CR boost, cool CR boost, warm non-boost CR and a cool non-boost CR to independently control intensity, color temperature, and CR outputs.
(FR)
L'invention concerne des procédés et des systèmes pouvant être utilisés pour commander indépendamment la température de couleur, l'intensité et/ou une réponse circadienne (CR) d'une ou de plusieurs sources de lumière (par exemple, des sources de lumière à spectre discret) pour régler une ou plusieurs de la température de couleur, de l'intensité et des mesures circadiennes dans un espace. Par exemple, un luminaire peut comporter quatre sources de lumière pouvant être commandées, une amplification de CR chaude, une amplification de CR froide, une CR non amplifiée chaude et une CR non amplifiée froide pour commander indépendamment des sorties d'intensité, de température de couleur et de CR.
