 EMI1.1 
 



   Es sind Glühlampen bekannt, bei denen die Stützen der   Metallglülifäcien   aus Kupfer oder einer Kupferlegierung bestehen. Kupfer hat für diesen Zweck bedeutende Vorzüge. 



  Es hat aber einen Nachteil, der darin besteht, dass es beim Brennen in der Lampe sehr weich wird und seine Federkraft vollständig verliert. 



   Dieser Nachteil wird nun gemäss vorliegender Erfindung dadurch vermieden, dass Kupfer mit einer Einlage aus Eisen, insbesondere ans Stahl, verwendet wird. Solcher mit Stahleinlage versehener Kupferdraht ist an und für   steh bekannt. Im vorliegenden Falle   werden durch die Anwendung dieses sogenannten Bimetalldrahtes einesteils die dem Kupfer

 EMI1.1
 



   Incandescent lamps are known in which the supports of the Metallglülifäcien are made of copper or a copper alloy. Copper has important benefits for this purpose.



  However, it has a disadvantage that is that it becomes very soft when burning in the lamp and completely loses its spring force.



   According to the present invention, this disadvantage is avoided in that copper is used with an insert made of iron, in particular on steel. Such copper wire provided with a steel core is known to and for stand. In the present case, the use of this so-called bimetallic wire partly reduces the copper wire
 EMI1.2
 Occasion is given.
