Abstract: A method and a circuit arrangement for operating a discharge lamp, in particular during the first hours of operation after lamp manufacture, are described. The method and the circuit arrangement are provided in particular for high-pressure gas discharge lamps (HID or high intensity discharge lamps or UHP or ultra high performance lamps). Furthermore, a lighting unit with a discharge lamp and such a circuit arrangement and a projection system with a projection display and such a lighting unit are described. Switching-over between various modes of operation with different operating frequencies serves to avoid that the burning voltage of the lamp drops into a region of a minimum voltage of a lamp driver unit below which the latter can no longer drive the lamp with its rated power or a desired power.

Abstract: A method and a circuit arrangement operate a discharge lamp, such as a high-intensity discharge lamp (HID) or ultra high performance lamps (UHP). The discharge lamp has first and second operating phases with a higher first or a lower second frequency of the lamp's alternating current (AC). The operating phases are activated alternatively at defined intervals and for defined periods of time, in order to achieve a stable arc discharge and only a low burnout or rise in burning voltage of the lamp during its life by configuring certain forms of electrode tips.

Abstract: 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 calculated 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').
