Abstract

Una pluralità di lampade a scarica, o fluorescenti, collegate in serie, è sottoposta, all'atto dell'accensione, ad una tensione variabile la cui frequenza viene variata, in un prefissato intervallo di tempo, tra valori estremi prefissati, rispettivamente massimo e minimo, in modo da provocare, con un conveniente valore di tale tensione, l'accensione di tali lampade con queste ultime successivamente alimentate con corrente costante a frequenza nominale.A plurality of discharge lamps, or fluorescent, connected in series, is subjected, at the moment of ignition, to a variable voltage whose frequency is varied, in a predetermined time interval, between predetermined extreme values, respectively maximum and minimum , so as to cause, with a convenient value of this voltage, the lighting of these lamps with the latter subsequently powered with constant current at nominal frequency.
