Abstract:
The invention describes a method of driving a gas-discharge lamp (1) wherein, at any one time, the lamp (1) is driven according to one of a plurality of different driving schemes (DS1, DS2) and the lamp power is controlled according to one of a plurality of different power control strategies (PCS, PCf, and wherein the lamp (1) is driven according to a first driving scheme (DS1) prior to a trigger event (tsw) and, upon occurrence of the trigger event (tsw), a driving scheme switchover is effected so that the lamp (1) is subsequently driven according to a second driving scheme (DS2), and wherein, in temporal dependence on the trigger event (tsw), a power controls strategy switch over is effected from a first power control strategy (PCs) to a second power control strategy (PCf) such that the lamp power is subsequently controlled according to the second power control strategy(PCf) for a time interval (tm, tf).
