  Metallfaden-Glühlampe mit gestützten hufeisenförmigen Fäden. 



   Bekanntlich werden die Metallfaden-Glühlampen mit hufeisenförmigen Metallfäden meistens vertikal nach abwärts hängend gebrannt, so dass die beim Glühen weich werdenden Fäden eine lotrechte Lage einnehmen. Bisher war es üblich, die Befestigungspunkte der Glühfäden an den Stromzuführungsdrähten so anzuordnen, dass sie sich senkrecht über den Mittelpunkten der   gebräuchlichen Verankerungen, Ösen, Häkchen   usw. befanden. 



   Die äusserst feinen und   zarten Fäden niederkerziger   Lampen erleiden aber selbst unter diesen   Umständen,   insbesonders bei Betrieb mit Gleichstrom derart starke Verkrümmungen, dass häufig zwei benachbarte Fäden zur   Berührung   kommen und die Lampen infolge Kurzschlusses 
 EMI1.1 
 
Die Ursache der auftretenden Verkrümmungen u. dgl. hat man bekanntlich in verschiedenen elektrodynamischen oder auch in gelegentlich auftretenden elektrostatischen Wirkungen, dann in Stauchungserscheinungen zu suchen. Es wurde gefunden, dass man die dadurch hervor- 
 EMI1.2 
 der Fäden der Tendenz zur   Verkrümmung   derselben entgegenwirkt.

   Diese Wirkung wird dadurch erreicht, dass   man   im Gegensatze zur bisher üblichen, eingangs erwähnten Anordnung der Befestigungspunkte des   hufeisenförmigen   Glühfadens an den Stromzuleitungsdrähten z. B. die Lötknoten oder Kittklloten so anordnet, dass sich dieselben bei einer hängenden Lampe nicht lotrecht über den Mittelpunkten der Verankerungen (Ösen, Haken oder dgl.) befinden. Zur

   In Fig. 1,   l   a und 1 h ist ein Ausführungsbeispiel der vorliegenden Erfindung dargestellt, bei welchem sich die Lötknoten einer Lampe in einem grösseren, wagerechten Abstand von der

  Metal filament light bulb with supported horseshoe-shaped filaments.



   As is known, the metal filament incandescent lamps with horseshoe-shaped metal filaments are mostly burned hanging vertically downwards, so that the filaments which become soft during the glow take up a perpendicular position. Up to now it has been customary to arrange the attachment points of the filaments on the power supply wires in such a way that they are perpendicular to the midpoints of the usual anchors, eyes, hooks, etc.



   Even under these circumstances, the extremely fine and delicate threads of low-core lamps, especially when operated with direct current, suffer from such strong curvatures that two adjacent threads often come into contact and the lamps come into contact with a short circuit
 EMI1.1
 
The cause of the occurring curvatures u. The like. As is well known, one has to look for various electrodynamic or occasionally occurring electrostatic effects, then in compression phenomena. It was found that the resulting

 of the threads counteracts their tendency to warp.

   This effect is achieved in that, in contrast to the previously usual, initially mentioned arrangement of the attachment points of the horseshoe-shaped filament on the power supply wires z. B. arranges the solder knots or putty putty so that they are not perpendicular to the centers of the anchors (eyes, hooks or the like.) With a hanging lamp. To

   In Fig. 1, l a and 1 h, an embodiment of the present invention is shown in which the solder nodes of a lamp at a larger, horizontal distance from the
