Abstract

Zur Herstellung der zweiseitig gequetschten Metall­ halogenidhochdruckentladungslampe (19) werden folgende Arbeitsgänge ausgeführt: Vorformen des Entladungsge­ fäßes (6) durch Einrollen mit N₂-Staudruckspülung, Einspannen in die Quetschvorrichtung, Einführen des ersten Eo-Systems (7, 8, 9, 10), wobei die Stromzu­ führung (9) zickzackförmig geknickt und an der Innen­ wand des Quarzrohres (1) selbsthalternd abgestützt ist, Herstellen der ersten Quetschung (12) mit Ar-Spülung, Hochvakuumglühen beim Einschleusen in die mit Xenon gefüllte Glovebox, Einbringen der Füllsub­ stanzen (14, 15), Einführen des zweiten Eo-Systems (7, 8, 9, 10), Dichtschmelzen des offenen Rohrendes mit Plasmabrenner, Entnehmen aus der Glovebox, Herstellen der zweiten Quetschung (18) bei gleichzeitigem Ausfrieren des im Entladungsgefäß (6) enthaltenen Xenon bei mindestens -112 °C, Entnehmen der Lampe (19) aus der Quetschvorrichtung und Entfernen der über­ stehenden Enden des Quarzrohres. Kein Pumprohr am Entladungsgefäß (6). To manufacture the double-sided crushed metal high pressure halide discharge lamp (19) are as follows Operations performed: preforming the discharge area barrel (6) by rolling in with N₂ back pressure flushing, Clamping in the crimping device, inserting the first Eo system (7, 8, 9, 10), the Stromzu guide (9) zigzag and bent on the inside Wall of the quartz tube (1) supported self-holding is producing the first pinch (12) with Ar flushing, high vacuum annealing when sluicing into the xenon-filled glovebox, introduction of filler punching (14, 15), introduction of the second eo system (7, 8, 9, 10), sealing the open pipe end with Plasma torch, removal from the glovebox, manufacture the second bruise (18) at the same time Freeze out the contained in the discharge vessel (6) Xenon at at least -112 ° C, remove the lamp (19) from the crimping device and removing the over standing ends of the quartz tube. No pump tube on Discharge vessel (6).
