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 eine 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 Glovebox, Einbringen der Füllsubstanzen (14, 15), Einführen des zweiten Eo-Systems (7, 8, 9, 10), Dicht­ schmelzen des offenen Rohrendes mit Plasmabrenner, Entnehmen aus der Glovebox, Herstellen der zweiten Quetschung (18) bei gleichzeitigem Kühlen des Entla­ dungsgefäßes (6), Entnehmen der Lampe (19) aus der Quetschvorrichtung und Entfernen der überstehenden Enden des Quarzrohres sowie ggf. der Enden der Strom­ zuführungen (9). 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 a 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 Glovebox, introduction of the filling substances (14, 15), Introducing the second Eo system (7, 8, 9, 10), sealing melt the open pipe end with a plasma torch, Remove from the glovebox, manufacture the second one Squeeze (18) while cooling the discharge dungsgefäßes (6), removing the lamp (19) from the Crushing device and removal of the protruding ones Ends of the quartz tube and possibly the ends of the current feeders (9). No pump tube on the discharge vessel (6).
