摘要： The invention relates to a circuit for operating a gas discharge lamp 400. The circuit comprises an inverter 300 for generating a high frequency current for a gas discharge lamp 400. The inverter 300 includes a single power switch 312, in order to keep the costs of the circuit low. The generated high frequency current is further amplitude modulated, in order to reduce a burning back of the electrodes of the lamp 400 and to increase the stability of the arc of the gas discharge lamp 400, respectively. A controller 500 of the circuit controls the amplitude modulation of the high frequency current that is generated by the inverter 300. The invention relates equally to an apparatus 1 comprising such a circuit and to a method of operating such a circuit.

摘要： A projection system for image reproduction by means of at least one lamp (10) as well as a sensor (30) for generating a sensor signal for monitoring changes in the luminous flux generated by said at least one lamp (10) and for compensating these changes through a suitable control of the image reproduction is described. The projection system comprises a device (31; 32; 36, 37) for eliminating substantially periodic interference components from the sensor signal generated by the at least one sensor (30; 301, 302, 303). These interference components may be generated by an optical component such as in particular a color modulator (12) of the projection system. The invention thus renders possible an at least substantially interference-free compensation of fluctuations in the luminous flux generated by the lamp (10), for example owing to an unstable arc discharge, also in those color systems in which the positioning of the sensor (30) in the projection system is non-critical.

摘要： The invention relates to an electronic circuit and to a method of operating a high-pressure lamp in various operational modes. The circuit comprises a DC-AC converter consisting of two half bridges (110-1) and (110-2). A series circuit comprising a first coil L1, the high-pressure lamp (120), and a second coil L2 is connected between the outputs (112-1) and (112-2) of these two half bridges. The invention has for its object to develop such a known circuit further such that it is equally suitable for an ignition mode and for a normal operational mode of the high-pressure lamp, without individual components having to be overdimensioned. According to the invention, this object is achieved in that a first capacitor C1 is connected in a path from the junction point of the first coil L1 and the high-pressure lamp (120) either to a reference potential (-) or to an operating potential (+), and in that a second capacitor C2 is connected in the path from the junction point of the high-pressure lamp (120) and the second coil L2 either to the reference potential (-) or to the operating potential (+) or in parallel to the high-pressure lamp (120).

摘要： The invention relates to an image projector with a High-Intensity-Discharge HID lamp (112) and a method of operating it. Such lamps have the disadvantage that their voltaic arc jumps back and forth between different positions at unforeseeable times during operation. This so-called arc jumping has the effect of changing the brightness, i.e. the overall brightness and / or the brightness distribution of the light emitted by the HID lamp (112). For the viewer of an image projected with such a projector, this effect appears as a jolt of this projected image. To avoid such effects for the viewer, it is first proposed according to the invention that changes in the brightness of the light in the image projector's beam path are detected. As soon as a change in brightness caused by an arc jump has been detected, this brightness is reset to a brightness detected at a moment t-2 before the arc jump, in order subsequently to convert it during a predetermined time interval T to the brightness resulting from the arc jump. This resetting must occur so soon after the arc jump, and the conversion so slowly, that the changes in the brightness of the light incident on a picture screen device (118) resulting from the arc jump, the reset, and the conversion are not perceptible to the human eye.
摘要翻译：本发明涉及具有高强度放电HID灯（112）的图像投影仪及其操作方法。这样的灯具有这样的缺点：它们的电弧在操作期间在不可预见的时间在不同位置之间来回跳动。这种所谓的电弧跳跃具有改变由HID灯（112）发射的光的亮度，即整体亮度和/或亮度分布的效果。对于使用这种投影机投影的图像的观看者，此效果显示为该投影图像的颠簸。为了避免对于观看者的这种影响，首先提出根据本发明，检测到图像投影仪的光束路径中的光的亮度的变化。一旦检测到由电弧跳跃引起的亮度变化，则该亮度被重置为在电弧跳跃之前的时刻t-2处检测到的亮度，以便随后在预定时间间隔T期间将其转换为亮度导致电弧跳跃。这种复位必须在电弧跳跃之后不久就发生，并且转换如此缓慢，使得由于电弧跳跃，复位和转换而导致的图像屏幕设备（118）的光的亮度变化是不可察觉的到人眼。

摘要： Supply circuits for supplying voltage and current signals to light sources (6) comprise switches (22, 32, 42, 52) and controllers (21, 31, 41, 51) to control the switches (22, 32, 42, 52) for reducing values of frequency components of harmonic content of power spectra of the light sources (6). By switching one of the voltage and current signals or by switching signals that result in one of the voltage and current signals, the other one of the voltage and current signals can be adjusted. The power spectrum of the light source (6) may be a function of the voltage and current signals. By adjusting one of them, the power spectrum can be adjusted such that values of frequency components of the harmonic content of the power spectrum are reduced. As a result, visible flicker is reduced in the light originating from the light source (6) without the use of energy storage capacitors for reducing this visible flicker.

摘要： The invention relates to an electronic circuit and to a method of supplying a high-pressure discharge arc lamp (12). The circuit comprises a DC-AC converter, for which purpose two controllable switching elements T1, T2 are connected in the form of a half bridge to an operating potential U+ and a reference potential (10). The circuit further comprises a two-stage filter arrangement. The lamp is connected to a coil Lign of the second filter stage, and the same connection terminal of this coil L ign is connected to the reference potential (10) via a capacitor C ign . To make the circuit as small and as economical as possible, while high high-frequency interference peaks and strong currents in the circuit are avoided, it is proposed that a coil Tr filt of the first filter stage has at least three taps. The first, outer tap is connected to the output of the half bridge, the second, central tap to the second connection terminal of the coil L ign , and the third, outer tap to the reference potential (10) via a capacitor C filt .

摘要： The invention relates to a method for operating a discharge lamp 11 including two electrodes 12,13. The method comprises applying to the electrodes an alternating current I Lamp . In order to improve the performance of the lamp and to increase the life time of the lamp, it is proposed that the alternating current has a direct current component DC for compensating a temperature difference between the two electrodes. The direct current component is selected more specifically such that a first electrode, which is expected to have a lower temperature than the second electrode, functions as anode for the direct current component, while the second electrode functions as cathode for the direct current component. The invention relates equally to an electronic circuit and to a software program for operating a discharge lamp correspondingly, as well as to a lighting system comprising a discharge lamp and means for operating this discharge lamp correspondingly.

摘要： A controller is described, which is particularly suited for a power supply with switching elements (S1, S2), such as a switching mode power supply. The controller comprises a logical unit (18) which calculates a binary state value Z k by a first logical operation from a binary input value I and a prior binary state value Z k- 1 . The logical unit further calculates a binary output value Y by a second logical operation from the binary input value I and the binary state value Z k . In this way, fast and efficient fully digital control may be realized especially for a switching mode power supply, where the binary input value I is a comparator value and the binary output value Y is used to drive the switch elements (S1, S2). An adaptation unit (20), which may be a signal processor, determines the logical operations and delivers them to the logical unit (18) during operation of the controller unit (16).
