Abstract
L'invention concerne un disjoncteur à DEL (23) destiné à être monté en série entre un pilote de DEL (21) et une source de DEL (22), le disjoncteur à DEL (23) comprenant : un commutateur commandé (231) monté en série entre le pilote de DEL (21) et une source de DEL (22) pour fermer ou ouvrir le circuit, un capteur (232) mesurant la puissance fournie par le pilote de DEL (21) à la source de DEL (22), le capteur (232) fournissant une mesure, un circuit de commande (233) connecté au capteur (232) pour recevoir la mesure et connecté au commutateur commandé (231) pour commander ledit commutateur, le circuit de commande (233) étant conçu pour : réaliser une intégration temporelle de la mesure pour obtenir une valeur d'éclairement (CNT) représentative d'une quantité d'éclairement ; ouvrir le commutateur commandé (231) lorsque la valeur d'éclairement dépasse un seuil prédéterminé.
