Abstract

Le but de l'invention est de fournir un dispositif d'illumination à LED pour éclairage intérieur/extérieur fonctionnant comme un éclairage mobile et comme un éclairage d'urgence, ainsi qu'un procédé de commande de l'éclairage de celui-ci. A cette fin, le dispositif d'illumination à LED comprend : un réseau de LED (208) disposé sur une surface plane ; une batterie secondaire (110) pour actionner le réseau de LED (208) dans le cas d'une panne d'électricité d'un réseau électrique commercial ; un convertisseur CC (202) qui actionne le réseau de LED (208) et qui permet également de charger la batterie secondaire (110) ; des unités de comparaison de tension (205, 604) qui comparent une tension de sonde et une tension de charge pour charger un moyen de batterie secondaire, ou comparent la tension de sonde et une tension de terre ; et une unité de commutation (209) qui allume ou éteint la sortie de l'unité de comparaison de tension (205). L'unité de comparaison de tension (205) effectue une commande de manière à allumer le réseau de LED en émettant la tension de sortie pour le moyen de batterie secondaire pendant les pannes de courant en fonction de la comparaison avec la tension de sonde.
