Abstract

Ce dispositif est du genre comportant un transformateur 27, dont le primaire est, par l'intermédiaire d'un convertisseur 16, branché aux bornes d'une source de courant continu 17, et dont le secondaire présente deux enroulements 25 pour le chauffage des filaments 11 du tube fluorescent 10 concerné. Suivant l'invention, et en combinaison, d'une part, le transformateur 13 est à entrefer important, et, d'autre part, à chacun des enroulements de secondaire 25 de ce transformateur est associée une capacitance 29. Application notamment aux blocs autonomes d'éclairage de sécurité.
