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.

Abstract:
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.
Abstract:
Die vorliegende Erfindung betrifft ein Leuchtmittel (23) und eine Fassung (20) für eine Leuchte (15). Die Merkmale der Fassung (20) können auch unabhängig von den Merkmalen des Leuchtmittels (23) realisiert werden. Die Fassung weist an mehreren Fassungsgehäuseseiten Versorgungsanschlussbereiche auf, so dass die elektrischer Versorgung und Verkabelung der Fassung (20) wahlweise von verschiede- nen Seiten oder auch gleichzeitig von mehreren Seiten erfolgen kann. Unabhängig von der Anzahl und der Anordnung der Versorgungsanschlussbereiche (94) sind an der Fassung (20) mehrere elektrische Versorgungsanschlüsse (95) gleicher Polarität vorhanden. Diese Versorgungsanschlüsse (95) gleicher Polarität sind elektrisch kurzgeschlossen. Zum Kurzschließen der Versorgungsanschlüsse gleicher Polarität dient jeweils ein Kurzschlussverbinder (116), wobei insbesondere zwei identische Kurzschlussverbinder (116) im Fassungsgehäuse angeordnet sind. Mit dieser Fassung (20) und dem Leuchtmittel (23) lassen sich modular sehr einfach große Gesamtleuchtflächen einer Leuchte (15) mit einem ästhetischen Gesamtbild erreichen.

Abstract:
The invention describes a method of shutting down a high pressure discharge lamp (1) in which a pair of electrodes (2) are disposed in an arc tube (3). This method comprises the steps of reducing the lamp power (PA) to a reduced operation level that enables the maintenance of an arc discharge between the electrodes (2) in a transition state from a lighting state to an extinguished state; driving the lamp (1) at the reduced operation level such that that the lamp (1) cools down; monitoring the lamp voltage (U) during this lamp power reduction process and during driving of the lamp (1) at the reduced operation level with regard to a defined discharge process stability criteria and increasing the lamp power (PA) if the discharge process stability criterion is not satisfied; completely shutting down the lamp power (PA) after sufficient duration to allow the lamp (1) to cool down to a state in which the gas pressure is such that the lamp (1) could be reignited shortly after being extinguished. Moreover the invention describes an appropriate driving unit (7) for driving a high pressure discharge lamp (1) and an image rendering system (40), particularly a projector system, comprising such a driving unit (4).

Abstract:
A method for operating a projection system (1) is described, wherein a brightness level (B 1 , B 2 , B 3 , B 4 , B 5 , B 6 ) in an image (IM) is represented by the total length of a number of light switch-on phases within a particular image cycle (VT). A high pressure discharge lamp (2) of the projection system (1) is operated via a lamp driver with an essentially square-wave alternating current (I L ) SO that an overshoot sequence (O), which occurs in the alternating current (I L ) 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 (O) lies essentially within a light switch-on or switch-off phase (t s ) 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.
