"Elektrische Glühlampe mit Quarzglaskolben"."Electric incandescent lamp with quartz glass bulb".
Die Erfindung betrifft eine elektrische Glühlampe mit einem Quarzglaskolben, der mit mindestens einer Quetschung versehen ist, in der Stromleiter, die aus einem Molybdänfolienstreifen bestehen, der an beiden Enden mit einem drahtformigen Leiter verbunden ist, mindestens mit dem streifenförmigen Teil eingeschmolzen sind,The invention relates to an electric incandescent lamp with a quartz glass bulb with at least one Pinch is provided, in the current conductor, which consists of a molybdenum foil strip, which at both ends with is connected to a wire-shaped conductor, are melted at least with the strip-shaped part,

Quetschungsmaterials auf. In den meisten Fällen ist die Lampe dann unbrauchbar geworden.Crushing material. In most cases, the lamp has then become unusable.
Bei Lampen dieser Art bleibt die Quetschungstemperatur im Betrieb unterhalb etwa 3OO°C, also unterhalb der Temperatur, bei der Molybdän an der Luft oxydiert. Der Sprung des Quetschungsmaterials ist somit nicht auf durch Oxydation des Molybdäns hervorgerufene Spannungen sondern auf eine örtlich zu hohe Stromdichte in den im der Quetschung vorhandenen Metallteilen, insbesondere im Übergang von dem drahtformigen Leiter auf den Molybdänfolienstreifen, zurückzuführen. In diesem Übergang können sehr hohe Temperaturen auftreten. Infolge einer ungleichen Ausdehnung der Quetschungsmaterialien treten Spannungen auf, die Sprung der Quetschung hervorrufen können, Die Erfindung bezweckt, eine Lampenkonstruktion zu schaffen, bei der diese Erscheinung vermieden wird.In lamps of this type, the pinch temperature remains below about 3OO ° C during operation, i.e. below the temperature at which molybdenum oxidizes in air. The crack of the squeezing material is thus not on stresses caused by the oxidation of molybdenum but on a locally too high current density in the metal parts present in the pinch, in particular in the transition from the wire-shaped conductor to the molybdenum foil strip, traced back. Very high temperatures can occur in this transition. As a result of an unequal Expansion of the crushing materials, tensions occur that can cause the crush to crack, The invention aims to provide a lamp construction in which this phenomenon is avoided.
Nach der Erfindung ist eine Lampe, bei der dieser Nachteil nicht auftritt, dadurch gekennzeichnet, dass der drahtformige, ausserhalb des Kolbens liegende Leiter an der Molybdänfolie unter Zwischenfügung einer Folie aus Vanadium oder einer Vanadiumlegierung festgeschweisst ist.According to the invention, a lamp in which this disadvantage does not occur is characterized in that the wire-shaped, outside of the piston lying conductor on the Molybdenum foil is welded with the interposition of a foil made of vanadium or a vanadium alloy.
Die Folie aus Vanadium oder einer Vanadiumlegierung kann eine Dicke zwischen 10 und 50/um aufweisen. Geeignete Vanadiumlegierungen sind Legierungen von Vanadium mit etwa 0,i£ bis etwa 10# Molybdän, Wolfram, Zirkon oder Hafnium.The foil made of vanadium or a vanadium alloy can have a thickness between 10 and 50 μm. Suitable Vanadium alloys are alloys of vanadium with about 0.1 to about 10 # molybdenum, tungsten, or zirconium Hafnium.
Die Verwendung der Zwischenfolie aus Vanadium ergibt eine Erniedrigung des Übergangswiderstandes an derThe use of the intermediate foil made of vanadium results in a lowering of the contact resistance at the

Diese Erscheinung könnte vielleicht dadurch erklärt werden, dass die an der Oberfläche der zu schweissenden Stellen vorhandene Oxydhaut sich in der Zwischenfolie löst und dadurch nicht mehr zu örtlich hohen Übergangswiderstand en führen kann.This phenomenon could perhaps be explained by the fact that the on the surface of the to be welded If the oxide skin is present in the intermediate film, it will no longer result in locally high contact resistance en can lead.
An Hand der Zeichnung, in der Fig. 1 in vergrössertem Masstab einen Schnitt durch eine Quetschung einer Lampe nach der Erfindung und Fig. 2 eine Ausführungsforir einer Lampe nach der Erfindung zeigen, wird die Erfindung ™ nachstehend näher erläutert.With reference to the drawing, in Fig. 1 in an enlarged Scale shows a section through a pinch of a lamp according to the invention and FIG. 2 shows an embodiment show a lamp according to the invention, the invention ™ will be explained in more detail below.

Halogenglühlampe bezeichnet. Der Kolben 1 hat eine Quetschstelle 2, in der ein Molybdänfolienstreifen 3 untergebracht ist. Auf einer Seite ist dieser Streifen 3 durch Schweissen mit einem Stromleiter k verbunden, der mit der Wolframwendel 5 verbunden ist. Am anderen Ende ist die Molybdänfolie 3 mit dem Stromleiter 6 verbunden, durch den die Lampe mit einer Stromquelle verbunden werden kann. Der g Stromleiter 6 ist gemäss der Erfindung am Molybdänstreifen 3 unter Zwischenfügung einer Folie 7 aus Vanadium festgeschweisst. Halogen light bulb called. The piston 1 has a pinch point 2 in which a molybdenum foil strip 3 is accommodated. On one side, this strip 3 is connected by welding to a current conductor k , which is connected to the tungsten filament 5. At the other end, the molybdenum foil 3 is connected to the current conductor 6, through which the lamp can be connected to a current source. The g current conductor 6 is firmly welded according to the invention the molybdenum strip 3 with the interposition of a film 7 of vanadium.
