Abstract

Zur Herstellung eines pumprohrlosen Entladungsgefä­ ßes (10) für eine Metallhalogenidhochdruckentla­ dungslampe wird zunächst aus einem einseitig ge­ schlossenen Quarzrohr mittels Formblasens ein Rohling hergestellt, dessen künftiges Entladungsge­ fäß mit einer Kuppe (9) versehen und in seiner Gestalt voll ausgebildet ist. Anschließend wird eine mit den Elektrodensystemen (12, 13, 14) verse­ hene, sich innerhalb des Rohlings selbst halternde Wechselaufnahme an eine vorbestimmte Position eingeführt. Es folgt ein Reinigungsspülvorgang mit Stickstoff, das Einbringen der Füllsubstanzen (20) sowie ein erneutes Aufheizen des Quetschungsbe­ reichs bei gleichzeitiger Stickstoffspülung und Kühlung der Kuppe (9) des Rohlings mit flüssigem Stickstoff. Nach dem folgenden Verschließen des Lampengefäßes (10) durch eine Quetschung (21) wird das überstehende Quarzrohrstück abgetrennt. Das Entladungsgefäß (10) wird anschließend auf eine ähnliche Weise mit einem Hüllkolben versehen. For the production of a discharge tube without a tube ßes (10) for a metal halide high pressure discharge The lamp is first made from a one-sided ge enclosed quartz tube by means of blow molding Blank produced, its future discharge ge provide a barrel (9) and in his Shape is fully formed. Then will one with the electrode systems (12, 13, 14) verses hene, self-supporting within the blank Exchange recording at a predetermined position introduced. A cleaning rinsing process follows Nitrogen, the introduction of the filling substances (20) as well as reheating the squeeze bag rich with simultaneous nitrogen flushing and Cooling the top (9) of the blank with liquid Nitrogen. After closing the Lamp vessel (10) by a pinch (21) the protruding piece of quartz tube was cut off. The Discharge vessel (10) is then on a similarly provided with an envelope flask.
