  • Publication number: 20110050115
    Abstract: A method of igniting a gas discharge lamp (2) comprises the steps of first applying a plurality of high-voltage ignition pulses with a relatively low amplitude and subsequently applying high-voltage ignition pulses with a relatively high amplitude. Switching over from generating low-amplitude ignition pulses to generating high-amplitude ignition pulses may be done on the basis of counting the low-amplitude ignition pulses or on the basis of monitoring the duration of the period during which the low-amplitude ignition pulses are generated.
