The invention describes a method of driving a discharge lamp (1), wherein a blackening value (N) is determined, which blackening value (N) represents a level of blackening of the interior of the lamp (1), and a recovery parameter (2, T) is calculate based on the blackening value (N). When the lamp power is increased above the saturation power level, the lamp (1) is driven according to the recovery parameter (2, T) for the duration of a specific recovery time. The invention further describes a driving arrangement (70, 70′), and a projector system (10) comprising a high-pressure discharge lamp (1) and such a driving arrangement (70, 70′). |
