    Wechselfadengliihbirlle.   



   Röhrenlampen mit mehreren Fäden sind bekannt. Gegenstand der Erfindung ist eine Röhrenlampe a mit mehreren gleichen oder verschiedenen Leuchtfäden b, die in bekannter Weise von isolierten Drahtstützen d in der Röhre gehalten werden und denen der Strom von Kontaktstellen e, die auf zylindrisehen oder vielkantigen Sockeln e liegen, auf der einen Seite zu-und der andern abgeführt wird. 



   Ist diese Birne z. B. mit drei   Glühfaden   und sechskantigen Kontaktsockeln ausgestattet, so kann   bei üblichem Einbau der Birne zwischen Klemmfassungen (Auslagen usw. ) durch Drehung der Birne   um 120  der abgebrannte Faden ausgeschaltet werden oder bei verschiedenen Glühfäden verschiedene Leuchteffekte erzielt werden.

    Alternate filament bulb.



   Multi-filament tubular lamps are known. The subject of the invention is a tube lamp a with several identical or different filaments b, which are held in the tube in a known manner by insulated wire supports d and to which the flow of contact points e, which lie on cylindrical or polygonal sockets e, on one side -and the other is taken away.



   Is this pear z. B. equipped with three filaments and hexagonal contact sockets, the burnt filament can be switched off by turning the bulb by 120 with the usual installation of the bulb between clamps (displays, etc.) or different lighting effects can be achieved with different filaments.
