Abstract

Die Erfindung hat Verfahren zur Herstellung einer Lampe (1) mit einem Leuchtsystem (2), einem damit vakuumdicht verbindbaren Glaskörper als Hüllkörper (4), einer Sockeleinheit (11) zur Montage der Lampe (1) im Beleuchtungskörper und mit den für den Betrieb jeweils notwendigen Zuleitungen (12), zum Gegenstand,
wobei durch Blasen ein einseitig offener Hüllkörper (4) und gleichzeitig damit eine Verschlußvorrichtung als Sockeleinheit (11) an dem anderen, geschlossenen Ende des Hüllkörpers (4) selbst ausgebildet wird, in die ansonsten geschlossene Sockeleinheit (11) Durchlässe (19) für die notwendigen Zuleitungen (12) eingebracht und dann nach Durchführung der Zuleitungen (12) vakuumdicht mit dem Hüllkörper (4) verschmolzen werden, und anschließend an dem Hüllkörper (4) selbst, durch Erwärmen und verengende Verformung an seinem offenen Ende ein Vakuumstutzen (6) ausgebildet wird, mit dessen Hilfe die Lampe (1) durch Zuschmelzen dieses Stutzens (6) nach Anlegen eines geeigneten Vakuums dauerhaft evakuiert wird. Die Erfindung bezieht sich ebenfalls auf die so hergestellte Lampe (1).

The invention relates to a method for producing a lamp (1) with a lighting system (2), a glass body that can be connected to it in a vacuum-tight manner as an envelope (4), a base unit (11) for mounting the lamp (1) in the lighting body, and with those for operation necessary supply lines (12), to the subject,
whereby an envelope body (4) which is open on one side and, at the same time, a closure device as base unit (11) at the other, closed end of the envelope body (4) itself is formed by blowing, into the otherwise closed base unit (11) passages (19) for the necessary Feed lines (12) are introduced and then, after the feed lines (12) have been carried out, are melted in a vacuum-tight manner with the enveloping body (4), and then a vacuum nozzle (6) is formed on the enveloping body (4) itself by heating and narrowing deformation at its open end , with the help of which the lamp (1) is permanently evacuated by melting this nozzle (6) after applying a suitable vacuum. The invention also relates to the lamp (1) thus produced.
