Abstract

Un système d'alimentation de lampes à décharge comprend essentiellement un réseau redresseur 21 alimenté par le secteur, un onduleur haute fréquence central 22 et un ensemble d'appareils d'éclairage 40 contenant chacun un ballast 42 et des lampes 44. Un circuit de commande d'amplitude 23 règle l'intensité lumineuse des lampes au niveau nécessaire, ce qui permet de réaliser une économie d'énergie.
