Abstract

La présente invention concerne un appareil comportant des éléments fluorescents à vide commandés par un circuit d'attaque, dont les générateurs de chaleur se trouvent dans un circuit de chauffage. Le circuit de chauffage de cet appareil contient un commutateur 6 commandé par un rythmeur 8, et la fréquence de répétition et le rapport travail/repos des impulsions de commande sont choisis de façon que la valeur efficace du courant de chauffage pulsé soit à peu près égale à celle du courant continu de chauffage des éléments. Application : montres ou appareils indicateurs montés sur des véhicules automobiles.
