Un dispositif d'éclairage (1) est pourvu d'une feuille de batterie solaire (3), d'une batterie de stockage (B) qui est chargée avec l'énergie générée par la feuille de batterie solaire (3), d'une unité d'émission de lumière (4) qui émet de la lumière, d'une unité de détection de quantité de génération d'énergie (31) qui détecte la quantité de génération d'énergie de la feuille de batterie solaire (3), et d'une unité de commande d'émission de lumière (21) qui, sur la base de l'énergie avec laquelle la batterie de stockage (B) est chargée, met en marche et arrête l'unité d'émission de lumière (4) cycliquement dans un cycle comprenant une période d'arrêt inférieure à 50 msec dans un cycle. L'unité de commande d'émission de lumière (21) continue le cycle de mise en marche et d'arrêt si la quantité de génération d'énergie détectée par l'unité de détection de la quantité de génération d'énergie (31) dans la période d'arrêt est inférieure à une valeur de référence d'arrêt prédéfinie, et si la quantité de génération d'énergie dépasse la valeur de référence d'arrêt, met fin au cycle de mise en marche et d'arrêt, et arrête l'unité d'émission de lumière (4).
