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.

摘要： The invention describes a method of shutting down a high pressure discharge lamp (1) in which a pair of electrodes (2) is disposed in an arc tube (3), which method comprises reducing, upon receipt of a shut-down request (SR), the lamp power (P) towards a reduced power level (PR) required to sustain a long-term arc discharge between the electrodes (2), and driving the lamp (1) towards the reduced power level (PR) for a reduced power duration before completely shutting down the lamp power (P), whereby, prior to reducing the lamp power (P) towards the reduced power level (PR), the lamp power (P) is reduced to an undershoot power level (Pu), which undershoot power level (Pu) is lower than the reduced power level (PR) required to sustain a long-term arc discharge between the electrodes (2), and the lamp is driven at this undershoot power level (Pu) for an undershoot power duration (tu) before increasing the lamp power (P) again to approach the reduced power level (PR). Moreover the invention describes an appropriate driving unit (4) for driving a high pressure discharge lamp (1) and an image rendering system (40), particularly a projector system, comprising such a driving unit (4).

摘要： This invention describes a method for driving a gas discharge lamp (1), whereby an alternating voltage (U) is applied to the gas discharge lamp (1), the alternating voltage (U) having a first polarity during a first time interval (tf1, ts1) and a second polarity opposite to the first polarity during a second time interval (tf2, ts2). In this method, the first time interval (tf1) and the second time interval (tf2) are repeated alternately during a first operation mode. During a second operation mode, the electrical power (P) being provided to the gas discharge lamp (1) is smaller compared to the first operation mode, and the first time interval (ts1) and the second time interval (ts2) are repeated alternately, whereby in this second operation mode the duration of the first time interval (ts1) is at least a multiple of the duration of the second time interval (ts2). Furthermore, the invention describes an appropriate driving unit (4) for driving a gas discharge lamp (1), and an image rendering system, particularly a projector system, comprising a gas discharge lamp (1) and such a driving unit (4).

摘要： A method and a circuit arrangement for the operation of a high-pressure gas discharge lamp (HID [high intensity discharge] lamp or UHP [ultra high performance] lamp) is described, which lamp is particularly suitable for illuminating projection displays with sequential color rendering (for example LCOS or SCR-DMD systems) with a pulsatory lamp current. Artefacts in the color rendering are avoided through the generation of at least one compensation pulse of a given amplitude and a given timing and through superimposition thereof on the lamp current.

摘要： The invention relates to a projection system for image representation, with a display (61), at least one lamp (10), and at least one sensor (7) for generating a sensor signal for monitoring and compensating changes in the luminous flux provided by the at least one lamp (10). To achieve a monitoring of the light quantity actually incident on the display (61) which is as accurate and as interference-free as possible, an optical component (31) is arranged in a light path between the lamp (10) and the display (61), which component allows a first light component to pass through and reflects a second light component such that one of the light components is directed at the display (61) and the other light component is directed at the sensor (7) arranged outside the light path. A sensor signal generated in this manner renders it possible to compensate for fluctuations in the luminous flux provided by the lamp (10) through the control of a lamp driver (101) in an effective manner and practically without light losses and without being influenced by the brightness fluctuations generated by a color modulator or other components of the system.

摘要： The invention relates to a DC—DC converter and a power supply unit formed thereby, with which a DC input voltage (Vdc) may be converted into two DC output voltages (U1, Usb) via a resonant switched-mode power supply. Via a circuit stage (M1, M2), a control circuit (C) generates a first AC voltage (VAC), which is converted via two resonant circuits with different transmission behavior and two rectifiers (G1, Gsb) in frequency-dependent manner into DC output voltages (U1, Usb). To achieve a standby mode, in which the first DC output voltage (U1) is designed to be very low and hardly any power is drawn on the output side, a second, thinner auxiliary circuit stage (M3, M4) is provided, which is coupled to the resonant circuits via an inductor (L2). The current consumption of the circuit in standby mode may be reduced considerably by appropriate dimensioning.
