Description

Elektrische lfehrfadenglühlampe mit am Sockeläangeordneten, mit den-freien Enden der Glühfäden verbundeneir IVIetallfedern. Die Erfindung betrifft eine elektrische Mehrfadenglühlampe, bei der die einzelnen Fäden durch am Sockel angebrachte Federn eingeschaltet werden.Electric filament light bulb with on the base, with the free ones The ends of the filaments are connected by metallic springs. The invention relates to an electrical Multi-filament incandescent lamp in which the individual filaments are driven by springs attached to the base be switched on.

Bei den bekannten Lampen sind die Enden der Glühfäden an zwei übereinander angeordnete, den Mittelkontakt der Glühlampe bildende Federn angeschlossen. Beim Einschrauben in die Fassung kommt somit erst die eine und bei weiterem Einschrauben auch die zweite Feder mit dem Mittelkontakt der Fassung in stromleitende Berührung. Die Reihenfolge der Einschaltung ist dadurch festgelegt.In the known lamps, the ends of the filaments are two on top of each other arranged, the central contact of the incandescent lamp forming springs connected. At the Screwing into the socket therefore comes first one and when screwing in further the second spring is also in electrical contact with the center contact of the socket. This determines the order in which they are switched on.

Gemäß der Erfindung werden die Kontaktfedern nicht übereinander, sondern nebeneinander angeordnet. Es steht daher frei, entweder die eine oder die andere Kontaktfeder so aufzubiegen, daß sie zuerst beim Einschrauben in stromleitende Berührung mit dem Mittelkontakt der Fassung gelangt.According to the invention, the contact springs are not on top of each other, but arranged side by side. It is therefore free to choose either one or the other Bend the contact spring so that it first comes into electrical contact when it is screwed in reaches the center contact of the socket.

Auf der Zeichnung ist die Erfindung dargestellt, und zwar zeigen: Fig. z und 2 Ansichten der Glühlampe, Fig. 3 und q. Querschnitte durch die Glühlampe.In the drawing the invention is shown, namely show: FIGS. Z and 2 are views of the incandescent lamp, FIGS. 3 and q. Cross sections through the light bulb.

Der Sockel b ist mit der Kittmasse c in bekannter Weise auf die Glühbirne ca aufgekittet. Die Enden f und i der Glühfäden d und e sind an das Sockelgewinde bei l und m angeschlossen. Die anderen Enden g und h sind mit den nebeneinander auf der Isolierung n angeordneten Federn q und r verbunden. Bei der gezeichneten Ausführung-wirdzunächst die aufgebogene Feder r an den Mittelkontakt der Fassung angedrückt und damit der Stromkreis für den Glühfaden e geschlossen. Bei weiterem Andrehen wird die Feder r so weit zusammengedrückt, daß der Mittelkontakt auch durch die niedrigere Feder q berührt und damit der Stromkreis für den Glühfaden d geschlossen wird. Für weitere Glühfäden wiederholt sich der Vorgang.The base b is cemented onto the light bulb ca with the cement compound c in a known manner. The ends f and i of the filaments d and e are connected to the base thread at l and m. The other ends g and h are connected to the springs q and r arranged side by side on the insulation n. In the embodiment shown, the bent spring r is first pressed against the center contact of the socket and the circuit for the filament e is thus closed. With further turning, the spring r is compressed so far that the center contact is touched by the lower spring q and the circuit for the filament d is closed. The process is repeated for further filaments.
