摘要： A discharge lamp, and particularly a high-pressure gas-discharge lamp (an HID (high-intensity discharge) lamp or UHP (ultra-high performance) lamp), having a reflector and a cooling means is described. The cooling means comprises at least one nozzle (3) by which a flow of gas can be directed onto the discharge lamp, the at least one nozzle (3) being so arranged that it does not extend, at least to any substantial degree, into a beam path produced by the lamp (2) and the reflector (1). In this way, the cooling means does not produce any obstacles on the beam path for the light. With preferred embodiments, it is possible to produce a turbulent flow that surrounds particularly the discharge vessel (21) of the lamp and that considerably increases the effectiveness of the cooling means. Further embodiments also allow the discharge lamp to be operated in a plurality of different positions without individual regions of the lamp being too little or too severely cooled.

摘要： Methods of driving a gas discharge lamp (1). In a first method, a value of voltage (Ul) across the gas discharge lamp (1) is determined, then a correction function (Kd) representing the dependency of light flux on a discharge arc length (d) is applied to calculate a required lamp power value (Pr) for a target light flux value (Ul). Finally, the gas discharge lamp (1) is operated according to the required lamp power value (Pr). In a second method, a value of voltage (Ul) across the gas discharge lamp (1) and a value of pressure (pl) inside the gas discharge lamp (1) are determined, then a correction function (Kp) representing the dependency of light flux on a discharge arc length (d) is applied to calculate a required lamp pressure value (pr) for a target light flux value by using the lamp voltage value (Ul) and the lamp pressure value (pl). Finally, the gas discharge lamp (1) is operated according to the required lamp pressure value (pr). Furthermore, the invention relates to appropriate driving units (4, 58) for driving a gas discharge lamp (1) and to an image rendering system, particulary a projector system, comprising gas discharge lamps (1) and such driving units (4, 58).

摘要： A lighting unit is described which has a discharge lamp (1), in particular a high pressure or high intensity discharge (HID) lamp or an ultra high performance (UHP) lamp, a lamp driver (2) and a cooling device (3). To reduce mechanical stresses caused by temperature variations in the lamp (1), one or more operating parameters of the lamp (1) are detected. In addition, a control unit is provided for controlling the lamp driver (2) and/or the cooling device (3) at least during switching on and/or off of the lighting unit in such a way that there is no excursion from a predetermined range of the at least one operating parameter. By selecting the parameter range suitably, the service life of the lamp may be extended considerably or the power of the lamp may be increased while the service life remains the same.
