摘要： Treating of a workpiece (W) which frequently undergoes heat-induced changes such as deformation, color changes and the like without using a cooling means for the workpiece (W) is achieved by the fact that, of the light which was incident from a rod-shaped lamp (1) on a trough-shaped cold mirror (2), the ultraviolet light (including some of the visible rays and infrared light) is reflected by the trough-shaped cold mirror (2) and by at least one other cold mirror (4,4',5) which is preferably plate-shaped. Furthermore, of the light which was emitted from the rod-shaped lamp (1) and which was incident on the other cold mirror(s) (2,4,4',5), the ultraviolet light (including some of the visible rays and infrared light) is reflected by the other cold mirror(s) (2,4,4',5). The light reflected by the other cold mirror(s) (2,4,4',5) is incident on the plate-shaped heat refraction filter (3) and some of the visible rays are reflected and are incident on a workpiece (W). The light emitted by the rod-shaped lamp (1) is not directly radiated onto the workpiece (W) via the heat refraction filter (3). Therefore, the IR component and the component of the visible rays which are emitted onto the workpiece (W) can be reduced and overheating of the workpiece (W) can be prevented.

摘要： Minimization of "color hue" and "flickering" on an irradiated surface such as a screen or the like, is achieved by the fact that, in a metal halide lamp of the short arc type which has a cathode (2) and an anode (1) in which at least rare earth halides and mercury are encapsulated and which is operated with an essentially horizontal discharge direction using direct current power, the cathode (2) has a tungsten electrode shaft (20) about which a tungsten coil (21) is wound, and the relationship 0.029 ) and I the current in steady-state luminous operation (A). In accordance with another aspect of the invention, the lamp is operable with a current I (amperes) in steady-state luminous operation in a range from 1.6 ) 0.045

摘要： A discharge lamp of the short arc type having an arc tube, a hermetically sealed tube at each of opposite ends of the, a pair of electrodes which are located in the arc tube, electrode rods which support the electrodes, support parts which are each formed by part of one of the hermetically sealed tubes, optionally cylindrical retaining bodies which are each located within and welded to a respective one of the support parts and in which a respective one of the electrode rods time is held securely, and a trigger component which is located on an outer side surface of the support parts, the support parts of the respective hermetically sealed tube and/or the cylindrical retaining bodies are formed of a material that contains a metal or a metallic compound for increasing the dielectric constant. In this way, even with a great distance between the electrodes of the lamp and a high gas filling pressure, the operating properties of the lamp can be improved and it can be reliably operated at a low breakdown voltage.

摘要： The rare gas discharge lamp is supplied with a current, which is lower than the rated current, the voltage of the rare gas discharge lamp is determined at this instant and the swing width of this voltage is measured. A comparator for comparing measured values of the swing width of the voltage of the rare gas discharge lamp when the current control supplies a reduced current, which is lower than the rated current. A service life converter for converting the difference value output by the comparison means into an indication of the service life of the rare gas discharge lamp.
