Abstract

L'invention concerne une ampoule de capteur de mouvement, incluant une structure d'enceinte ; un organe de réglage disposé sur une surface de la structure d'enceinte ; et un élément électroluminescent (6), un élément de commande (4) d'électroluminescence, un élément de contrôle (2), un circuit de détection d'événement (3), et un circuit de réglage de retard (5) disposé dans la structure d'enceinte. Le circuit de détection d'événement (3) détecte si un premier événement déclencheur se produit dans une zone et, lorsqu'un premier événement déclencheur se produit, génère et envoie un premier signal déclencheur à l'élément de contrôle (2). Le circuit de réglage de retard (5) envoie des informations de retard à l'élément de contrôle (2), lesquelles sont déterminées en fonction d'une opération d'utilisateur sur l'organe de réglage. L'élément de contrôle (2) reçoit le premier signal déclencheur et envoie le premier signal de contrôle à l'élément de commande (4) d'électroluminescence après avoir retardé une première durée en fonction des informations de retard. L'élément de commande (4) d'électroluminescence commande l'élément électroluminescent (6) pour qu'il émette de la lumière en fonction du premier signal de contrôle.
