摘要： To provide a high-pressure lamp capable of carrying lamp currents of 100 eres and higher, an essentially rotation-symmetrical discharge space (2) has two cylindrical necks (3, 4) melt-sealed thereto. Each one of the necks is formed of at least two telescoped hollow cylindrical quartz glass tubes (19, 27) which, with sealing foils circumferentially located within the neck, are all gas-tightly melt-sealed together. The sealing foils, typically of molybdenum, are electrically connected to a molybdenum disk (7, 8), for example by being welded to the circumference thereof which, in turn, is soldered to an end portion of an electrode shaft (5, 6), typically of tungsten, which extends into the discharge space of the discharge vessel. During manufacture, the inner quartz glass tube (27) is formed with a ring-shaped expansion or distention (23) which is melt-sealed to the inner wall of the outer glass tube (19), to permit flushing of the space between the glass tubes and where the sealing foils are located, for example flushing with argon, and subsequent melt-sealing with a vacuum of 20 mbar argon, while introducing 1 bar air pressure into the interior of the inner tube. After the neck structure is gas-tightly sealed together, the enlargement or distention together with an adjacent portion of the neck structure, is severed.

摘要： Ultraviolet (UV) radiation in the UV-C and UV-B bands, which is particularly dangerous, is absorbed and filtered by quartz glass doped with between 0.065% and 3.25%, and preferably between 0.065% and 1.3%, by weight, of cerium metal, or cerium as such. Preferably, the cerium is added to quartz sand and/or rock crystal, in form of a fine-grained powder of up to 20 .mu.m grain size, in form of cerium aluminate (CeAlO.sub.3), present in up to about 5% by weight, and preferably up to about 2%, by weight, and melted together in a single step. The quartz glass so obtained is particularly suitable for a metal halide discharge lamp, e.g. as an outer envelope (1), or as the discharge vessel (27) itself, or for halogen incandescent lamps, to form the quartz-glass light bulb or an envelope therefor. A small quantity of titanium oxide, up to about 0.05%, may be added as a further doping agent to the melt to further improve the UV absorption in the B and C bands.

摘要： To permit high lamp currents to be applied to lamp electrodes (5, 6) of a discharge vessel (2) from which two elongated necks (3, 4) extend via current supply leads (23, 35), the discharge vessel is first made as a generally rotation-symmetrical element, to which tubular cylindrical neck tubes (17) are sealed. A cylindrical plug element (26, 40) is placed in the neck tube adjacent the discharge vessel. A subassembly is then made of a core element, which can be constructed as a single or a composite structure of quartz glass, for example by telescopically fitting quartz glass tubes over a central core, and melt-sealing the tubes and core together. Molybdenum disks (7, 8; 22) are placed against the end faces of the core element, and a plurality, for example four, molybdenum connecting foils (11-16, 27) are secured to the circumferences of the disks, to axially connect them together. The subassembly is then introduced into the neck tube through the plug element, a further quartz glass tube is placed over the current supply lead (23) and formed with a bulbous enlargement, which is sealed to the interior of the neck portion. The basic lamp structure is now complete. neck portion, with the core element and foil-connected disks therein is then flushed. After flushing, the disks, foils, and core element are all melt-sealed together within the neck tube and the bulbous portion of the quartz tube, together with the remaining portion of the neck tube, is severed.

摘要： To maintain a predetermined design color temperature throughout the lifet of a metal halide high-pressure discharge lamp, particularly suitable for illumination of theaters, film or television studios, the discharge vessel of the high-pressure lamp, typically made of quartz glass, contains a fill which, besides mercury, has a noble gas, cesium and dysprosium halide and a nickel halide. Optionally, gadolinium halide may be used. Per cubic centimeter of volume of the discharge vessel, 0.03 to 3 mg dysprosium, 0.002 to 0.5 mg nickel, and, optionally, 0.002 to 0.1 mg gadolinium are suitable. Suitable halogens for the halides are iodine and bromium, preferably in a mol relationship between 0.2 and 1.5. The metals, nickel and gadolinium limit the color temperature drop-off over the average lifetime of the lamp to at the most 1 K per operating hour of the lamp.
