摘要： Ignition of a gas discharge lamp 10, which has a gas containing main space and two inner electrodes, of a lighting unit 4 of a lighting system is achieved by the use of a high frequency resonance circuit. The resonance circuit is connected to the inner electrodes and to a supply device 2, which supplies an alternating supply voltage. An outer electrode 22 is arranged near one the inner electrodes and to a node of the resonance circuit. Upon supplying the supply voltage a high voltage alternating burst will be generated at the outer electrode. This will result into a discharge of the gas in the main space. In turn, this will induce a discharge of the remaining gas. Then the frequency of the supply voltage will increase and a small reactive current only will remain to flow through the resonance circuit.

摘要： The invention relates to a standby circuit, an electrical device with a standby circuit, a method for the control of the electrical device and a power supply assembly. Whereas the power supply unit and the control electronics are in permanent operation when conventional devices are in the standby mode and consequently have a high power consumption, the invention proposes a solution for saving energy while retaining convenience of operation by which the power supply unit is switched off in the standby mode. A standby circuit, preferably fed by an energy buffer element, remains active in the standby mode and monitors signal inputs for activation events. When an activation event occurs, the standby circuit switches on the power supply unit.

摘要： There is described a method for operating a high-intensity discharge lamp (2), in which the high-intensity discharge lamp (2) is acted upon by an AC current (I) which commutates between positive pulses (Ip) and negative pulses (In) with a predefined current amplitude (IA), wherein a pulse width ratio between the pulse width of a positive pulse (Ip) and the pulse width of an adjacent negative pulse (In) is modulated in such a way that the mean current value (I) of two successive positive and negative pulses (Ip, In) fluctuates periodically between positive and negative values. In addition, the value of the current amplitude (IA) is modulated in accordance with a predefined modulation function (M). A description is also given of a corresponding lamp driver (10) for a high-intensity discharge lamp (2) and of a projection system (1) comprising such a lamp driver (10).
