Abstract
Un appareil déclairage qui peut comporter un convertisseur de tension fonctionnel pour fournir un courant à au moins deux canaux DEL raccordés entre un rail haute tension et un rail basse tension reliés à la sortie du convertisseur de tension est divulgué. Les canaux DEL peuvent être exploités pour permettre sélectivement à un courant dy circuler. Lappareil déclairage peut également comporter un module de contrôle fonctionnel pour contrôler le courant total du convertisseur de tension et le courant dans chacun des canaux DEL. Le module de contrôle peut également être fonctionnel pour régler les signaux de contrôle respectifs en vue de maintenir un courant total constant du convertisseur de tension tout en permettant des aspects de production déclairage, y compris lintensité, la couleur, et la température de couleur à régler et varier. De plus, le module de contrôle peut être fonctionnel pour synchroniser les divers signaux de contrôle, obtenir un échantillon représentatif du courant dans le convertisseur de tension et exploiter différents modes.
