Description

Elektrische Glühlampe mit umschaltbaren Glühfäden und einem bei eingeschraubter Lampe außerhalb des Fassungsgewindes liegenden Schaltring. Es sind bereits elektrische Glühlampen mit umschaltbaren Glühfäden bekannt, bei welchen das an der Lampe angebrachte Umschaltmittel bei eingeschraubter Lampe außerhalb des Fassungsgewindes liegt und ohne Lösung der Lampe zugängig ist. Die vorliegende Erfindung besteht darin, daß auf den Fassungsgewinde der Lampe ein Gewindering verschraubbar ist, der in den beiden End- oder Kontaktstellungen gegen den Kontaktring oder gegen die Lampenfassung festgeschraubt und dadurch in seinen Kontaktstellungen gesichert wird. Es kann daher eine unbeabsichtigte Lösung und Kontaktunterbrechung nicht stattfinden.Electric light bulb with switchable filaments and one with screwed in Lamp outside of the socket thread lying switching ring. They are already electric Incandescent lamps with switchable filaments are known, in which the attached to the lamp Switching means is outside the socket thread when the lamp is screwed in and is accessible without removing the lamp. The present invention is that A threaded ring can be screwed onto the socket thread of the lamp, which is inserted into the both end or contact positions against the contact ring or against the lamp socket is screwed tight and thereby secured in its contact positions. It can therefore an unintentional release and interruption of contact do not take place.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigen Abb. t und 2 eine Glühlampe mit dem verschraubbaren Kontaktring in den beiden Endlagen.In the drawing, an embodiment of the invention is shown, namely Fig. t and 2 show an incandescent lamp with the screwable contact ring in the two end positions.

Die Glühlampe i ist mit zwei Glühfäden 2, 3 versehen. Das eine Ende des Glühfadens 2 ist mit dem Metallring d. und das eine Ende des Glühfadens 3 mit dem Befestigungsgewinde 5 der Lampe stromleitend verbunden, während das andere Ende der beiden Glühfäden durch den Stromzuführungsdraht 6 mit dem Kontakt 7 verbunden ist. Auf dem Befestigungsgewinde 5 ist ein Gewindestück 8 verschraubbar, durch das in der oberen Endlage (Abb.2) die stromleitende Verbindung zwischen dem Metallring 4. und dem Gewinde 5 hergestellt und damit der Glühfaden :2 eingeschaltet wird, während in der unteren Endlage der Glühfaden 3 eingeschaltet ist (Abb. i). In beiden Endlagen liegt der Gewindering 8 außerhalb des Fassungsgewindes 9, so daß die Umschaltung der Glühfäden bewerkstelligt werden kann, ohne daß die Lampe gelöst zu werden braucht. Der Gewindering 8 liegt hierbei in der oberen Endlage gegen den Ring q. und in der unteren Endlage gegen die Lampenfassung 9 an, so daß er in seinen beiden Endstellungen gesichert ist.The incandescent lamp i is provided with two filaments 2, 3. The one end of the filament 2 is with the metal ring d. and one end of the filament 3 with the fastening thread 5 of the lamp is electrically connected, while the other end of the two filaments are connected to the contact 7 by the power supply wire 6 is. A threaded piece 8 can be screwed onto the fastening thread 5 through which in the upper end position (Fig. 2) the conductive connection between the metal ring 4. and thread 5 and thus the filament: 2 is switched on, while the filament 3 is switched on in the lower end position (Fig. i). In both End positions of the threaded ring 8 is outside of the mounting thread 9, so that the switchover the filaments can be done without detaching the lamp. The threaded ring 8 is in the upper end position against the ring q. and in the lower end position against the lamp socket 9 so that it is in its two end positions is secured.
