Abstract (en)
A starting assistance device for use in conjunction with an ignition device 14 for a gas discharge lamp 10 applies high voltage starting pulses to the lamp. The starting assistance device comprises a voltage sensitive solid-state device, such as two zener diodes ZD1 and ZD2 connected in parallel with the ignition device 14, and provides a low impedance return path for the high voltage starting pulses when the ignition device is operating. As soon as the device switches off, the starting assistance device assumes a high impedance state.
