Abstract

Un contrôleur de lampe muni d'une fonction unique d'accès à la lampe destiné à un système de contrôle de la sous-section d'éclairage électrique comprend un moyen de commutation du contrôle de l'éclairage à contenu accessible (39) qui sert à convertir les commandes de contrôle transmises dans un bus (2) en des signaux de commutation de contrôle d'événement et à sortir les signaux sur un moyen d'établissement d'événement lumineux (42) qui permet de décoder les signaux de commutation de contrôle d'événement et les signaux de commutation d'intensité lumineuse de la lampe unique, depuis le moyen de commutation de contrôle d'éclairage à contenu accessible (39) et les signaux de données d'événement et de lumière établis par ce dernier, et à sortir les résultats décodés sur une commande de la source lumineuse (34) pour commander l'allumage ou l'extinction de la source lumineuse (35) et pour réguler sa luminosité. L'utilisation du régulateur de la lampe permet de disposer d'une certaine souplesse pour contrôler la lampe, de simplifier la fabrication et l'utilisation du moyen de commutation de contrôle de l'éclairage à contenu accessible, de réduire les coûts et de répandre aisément les systèmes de contrôle lumineux numérique.
