摘要： A discharge lamp lighting device includes a power converter configured to receive a power from a power source, convert it into a voltage required by a discharge lamp and supply the voltage to the discharge lamp; and a controller which controls the power converter to drive the discharge lamp. The controller controls the power supplied to the discharge lamp according to a predetermined power curve. The controller controls the power curve to change based on at least one of a source voltage of the power source, an ambient temperature, a device temperature, a discharge lamp temperature and a discharge lamp voltage, and sets a sustained period of a max power value to a predetermined time period when the lighting of the discharge lamp is performed in a state where the discharge lamp temperature is equal to or less than a reference temperature.

摘要： Die Betriebszustände eines elektronischen Vorschaltgeräts mit Vollbrücke sowie die der betriebenen Lampe sollen mit einfacheren Mitteln überwacht werden können. Daher ist eine Messeinrichtung (R, GR) zum Messen des Stroms durch eines der vier Schaltelemente (S1 bis S4) der Vollbrücke vorgesehen. Ein entsprechender Strommesswert wird für eine Steuereinrichtung (ST) bereitgestellt. Die Vollbrückenschaltung (V) kann dann in Abhängigkeit des Strommesswertes gesteuert werden. Bei unerwünschten Zuständen lässt sich das elektronische Vorschaltgerät dadurch automatisch abschalten.

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 (tfl, tsl) and a second polarity opposite to the first polarity during a second time interval (tf2, ts2). In this method, the first time interval (tfl) 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 (tsl) and the second time interval (ts2) are repeated alternately, whereby in this second operation mode the duration of the first time interval (tsl) 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).
