CIRCUIT ARRANGEMENT FOR IGNITING AND OPERATING GAS DISCHARGE LAMPS

摘要

PHD. 84-145 13 In a circuit arrangement for igniting and operating gas discharge lamps having a choke coil (1) arranged between lamp (2) and a.c. supply source and comprising an inductivity L and an ignition device (3) connected to the lamp, a capacitor (9) having a capacitance C is connected in parallel with at least a part of the choke coil in order to obtain an ignition current increased with respect to the normal lamp operating current the capacitive reactance of this capacitor being .
