Abstract
La présente invention concerne une lampe à tube à diodes électroluminescentes (DEL) (500), pour laquelle un circuit de détection d'installation (2520) est configuré de sorte à recevoir un signal de commande externe. Le circuit de détection d'installation (2520) est configuré de sorte à détecter pendant un ou plusieurs signaux d'impulsion si la lampe à tube à DEL (500) est correctement installée sur une douille de lampe, en se basant sur la détection d'un signal généré à partir du signal de commande externe. Le circuit de détection d'installation (2520) comprend un circuit de commutation (2580, 2680, 2780, 2880) couplé au circuit de génération d'impulsions (2540, 2640, 2740, 2840), le ou les signaux d'impulsion commandant l'activation et la désactivation du circuit de commutation (2580, 2680, 2780, 2880). Le circuit de détection d'installation (2520) est en outre configuré de sorte : lorsqu'il est détecté pendant un ou plusieurs signaux d'impulsion que la lampe à tube à DEL (500) n'est pas correctement installée sur la douille de lampe, à commander le circuit de commutation (2580, 2680, 2780, 2880) de sorte à rester dans un état désactivé afin de contraindre une boucle de puissance de la lampe à tube à DEL (500) à être ouverte; et lorsqu'il est détecté pendant un ou plusieurs signaux d'impulsion que la lampe à tube à DEL (500) est correctement installée sur la douille de lampe, à commander le circuit de commutation (2580, 2680, 2780, 2880) de sorte à rester dans un état conducteur pour contraindre la boucle de puissance de la lampe à tube à DEL (500) à conserver un état conducteur.
