    摘要: A projection system and a method for operating a discharge lamp are described. The protection system comprises a discharge lamp 12 and driving electronics 14. The color wheel 18 serves as color filter for filtering light 16 emitted from lamp 12 to generate a light sequence 20 with different colors in sequential color time periods 22, 22a. In between color time periods 22, 22a, spoke time periods 24, 24a are arranged. The driving electronics provide a lamp current I with superimposed first current pulses, which are generated in at least one of the color time periods 22, 22a. In order to allow greater flexibility and be able to achieve stable arc operation and constant color point over lamp lifetime, the driving electronics 14 further provide second current pulses superimposed on the lamp current. The second current pulses are generated during at least one of the spoke time periods 24, 24a.

Subsequently, the actual current (I) of the discharge lamp (1) is controlled regulated according to a momentary required waveshape (RW) which is determined based on the target light waveshape (LWT, LWT′) and the waveshape correcting function. Moreover the invention describes an appropriate driving unit (11) for driving a discharge lamp (1) and a projection system (10), comprising such a driving unit (11).

A high pressure discharge lamp (2) of the projection system (1) is operated via a lamp driver with an essentially square-wave alternating current (IL) SO that an overshoot sequence (0), which occurs in the alternating current (IL) after a current zero crossing during operation of the high pressure discharge lamp (2), has a frequency so high that for each possible brightness level at least one full period (P) of the overshoot sequence (0) lies essentially within a light switch-on or switch-off phase (ts) following the zero crossing. A projection system (1) and a lamp driver (10) for a high pressure discharge lamp (2) in such a projection system (1) are also described.
