Abstract

Circuit inclut des moyens de commutation commandés, un organe à conductivité unidirectionnelle, des moyens de connexion de la lampe à une source de courant, et des organes inductifs associés aux moyens de commutation soient actionnés de manière répétitive et séquentielle à des intervalles de temps prédéterminés, ceci pour que des impulsions de courant continu soient appliquées à la lampe pour en contrôler le fonctionnement; Application notamment aux circuits d'allumage pour lampes à vapeur de sodium.Circuit includes controlled switching means, a unit with unidirectional conductivity, means for connecting the lamp to a current source, and inductive members associated with the switching means are actuated repetitively and sequentially at predetermined time intervals, this is so that direct current pulses are applied to the lamp to control its operation; Application in particular to ignition circuits for sodium vapor lamps.
