    • A lamp driver (1) for driving a gas discharge lamp (2) comprises: - a lamp current-generating section (10) for generating a constant lamp current commutating at a commutation frequency, the lamp current-generating section (10) having output terminals (13, 14); - a high-frequency section (20) comprising a waveform generator (21) for generat ing an alternating current component; - a coupling device (40) for adding the alternating current component generated by the high-frequency section (20) to the commutating lamp current generated by the lamp current-generating section. In an ignition mode, the high-frequency sect ion is used to generate ignit io n pulses at an ignition frequency which is higher than the commutation frequency. In an arc-straightening mode, the high-frequency section is used to generate a current ripple at a ripple frequency which is higher than the commutation frequency and differs from the ignition frequency, the ripple having an amplitude which is lower than the amplitude of the ignition pulses.
