ABSTRACT:
A starter for igniting a gas and/or vapor discharge tube (1) comprising two main electrodes 53, 54 and an auxiliary electrode 70. The discharge tube is connected to an inductive stabilization ballast 52. The starter applies an ignition voltage between the auxiliary electrode and a main electrode of the discharge tube. Tube ignition is promoted by connecting a capacitor 55 in series with a semiconductor switching element 58 across the starter input terminals A,B so that - in addition to the said ignition voltage - an increased voltage is generated between the two main electrodes of the discharge tube by cooperation of the inductive ballast and the capacitor.
