摘要： To improve the arc stability of high-pressure discharge lamps, particularlyf power ratings of up to about only 250 W, the cathode (4) is formed as an elongated, essentially cylindrical base body (8) having a tapering, conical region (9) terminating in a tip (10). The base body (8), only, is covered with a carbide coating along its length, except for an end portion for electrical connection; the carbide coating starts at the junction or transition between the cylindrical base body portion and the conical end portion. This cathode construction is easier and cheaper to make than prior art cathodes, by coating an essentially cylindrical cathode and then etching or grinding and polishing the tapering end region (9). The electrode is preferably made essentially of tungsten, doped with thorium oxide present up to about 0.6%, optionally also potassium, aluminum and silicon in tiny amounts. The electrode spacing is between 0.4 to 0.8 mm, and when used as a mercury high-pressure discharge lamp, filled with 70 to 130 mg per cubic centimeter mercury; when used as a xenon lamp, the xenon fill is preferably present at a cold fill pressure of between about 2 and 15 bar.

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.
