FIELD: electric engineering, possible use for igniting gas-discharge lamps.
SUBSTANCE: igniting device for gas-discharge lamp contains starter of glowing charge, resistor and posistor, serially connected thereto. In parallel to starter an additional resistor is connected, value of which is selected from condition: Rth Uc/(Un-Uc)>Ra>Rtc Uc/(Un-Uc), where Ra - value of additional resistance, Un - amplitude of network voltage, Uc - voltage of combustion of charge in starter, Rth - total resistance of resistor and posistor in hot state, Rtc - total resistance of resistor and posistor in cold state.
EFFECT: increased reliability of operation of igniting device, increase lifetime of igniting device.
