Abstract

La présente invention a trait à un système de commande d'éclairage (10) qui comprend un capteur optique (12) permettant de mesurer un environnement lumineux qui est obtenu au moyen d'une source lumineuse (100) où l'état électroluminescent peut être réglé et un dispositif de réglage de l'éclairage (110) permettant de régler la sortie de la source lumineuse (100) en fonction de la valeur de mesure du capteur optique (12). En se basant sur les conditions d'éclairage, le dispositif de réglage de l'éclairage (110) détermine la corrélation sur l'environnement lumineux à la fois de la position de placement de capteur optique (2) et d'une position de réglage (3) équivalant à une position souhaitée afin de régler l'environnement lumineux. Le dispositif de réglage de l'éclairage (110) comprend un dispositif de réglage de la sortie (116) permettant de régler la sortie de la source lumineuse (100) de sorte que l'environnement lumineux dans la position de réglage (3) atteint une valeur cible en fonction des corrélations et de la valeur de mesure du capteur optique (12). Une technique est de la sorte fournie et permet de ne pas devoir disposer le capteur optique (12) dans une position souhaitée afin de régler l'environnement lumineux ainsi que de contrôler la source lumineuse de manière à régler l'environnement lumineux dans cette position.
