  Gasgefüllte elektrische Glühlampe mit   Mehrfaehwendelleuchtkörper und Sicherung.   



   Die Erfindung bezieht sich auf eine gasgefüllte elektrische   Glühlampe   mit einem Mehrfachwendel-   leuchtkörper.   Vorgeschlagen wurde bereits, solche Lampen mit einer Schmelzsicherung zu versehen. 



  Die Erfindung betrifft eine besondere Wahl des Materials dieser Sicherung. 



   Gemäss der Erfindung wird das Material derart gewählt, dass die   Kurzsehlusskonstante   kleiner ist als ungefähr 300   X   106.   Unter Kurzschlusskonstante"ist   hier die Konstante C gemeint aus der Meyerschen Formel : 
 EMI1.1 
 
 EMI1.2

  Gas-filled electric light bulb with multi-filament filament and fuse.



   The invention relates to a gas-filled electric incandescent lamp with a multiple filament luminous element. It has already been proposed to provide such lamps with a fuse.



  The invention relates to a particular choice of material for this fuse.



   According to the invention, the material is selected in such a way that the short-circuit constant is less than approximately 300 X 106. The short-circuit constant "here means the constant C from Meyer's formula:
 EMI1.1
 
 EMI1.2
