Abstract

La présente invention concerne un dispositif d'éclairage pourvu d'un générateur d'énergie électrique dans lequel de l'énergie électrique est générée par énergie renouvelable, d'une batterie de stockage, et d'une source lumineuse, le risque que la lumière s'éteigne même durant une panne de courant étant moins probable. La présente invention concerne en particulier un dispositif d'éclairage pourvu d'un dispositif à cellule solaire (1), d'une batterie de stockage (2) qui est chargée au moyen de l'énergie électrique fournie à partir du dispositif à cellule solaire (1), d'une unité d'éclairage (40) qui émet de la lumière au moyen de l'énergie électrique fournie à partir de la batterie de stockage (2), et d'un dispositif de commande (3) qui commande la charge et la décharge de la batterie de stockage (2), le dispositif de commande (3) étant pourvu d'une fonction permettant de réaliser une première commande de décharge dans laquelle, au cours du fonctionnement normal, la décharge de la batterie de stockage (2) est arrêtée alors qu'au moins une partie de la capacité de stockage de la batterie de stockage (2) reste, et une seconde commande de décharge dans laquelle la batterie de stockage (2) est déchargée jusqu'à sa limite inférieure de décharge lors de l'étude de la capacité de stockage de la batterie de stockage.
