Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Gegenstand vorliegender Erfindung bildet eine neue Lösung einer elektrischen Serienglühlampe mit Sicherheitsfaden. Die Zeichnung zeigt beispielsweise eine niedervoltige Glühlampe, wie. solche zu Dekorationszwecken als Kugellampe, zu Christbaumbeleuchtungen als Kerzenlampe verwendet wird, und zwar Fig. ι eine Seitenansicht, Fig. 2 eine Draufsicht.The subject of the present invention is a new solution to an electrical one Standard light bulb with safety thread. For example, the drawing shows a low voltage Incandescent lamp like. those for decorative purposes as ball lamps, for Christmas tree lighting is used as a candle lamp, namely Fig. ι a side view, Fig. 2 a top view.

Abweichend von ähnlichen Lampen ist der längere Sicherheitsfaden s innerhalb des Leuchtfadens / so angeordnet, daß er in einem Winkel von 90° unter dem inneren Bogen des Leuchtfadens / hindurchgeht. Dadurch wird bezweckt, daß bei normalem Brennen der Lampe keinerlei Schattenbildungen gegen die Lampenwandung bzw. Spitze auftreten können, und dadurch wird der bei Dekprationsbeleuchtungen mit niedervoltigen Glühlampen mit Sicherheitsfaden äußerst störende, den Lichteffekt stark beeinträchtigende Mangel behoben.Unlike similar lamps, the longer security thread s is arranged within the filament / so that it passes under the inner arc of the filament / at an angle of 90 °. The aim of this is that when the lamp is burning normally, no shadows whatsoever can occur against the lamp wall or tip, and this eliminates the deficiency which is extremely disturbing in decorative lighting with low-voltage incandescent lamps with safety thread and which severely impairs the light effect.

Im übrigen tritt der Sicherheitsleuchtfaden s erst nach erfolgtem Durchbrennen des normalen Leuchtfadens / selbsttätig in Wirkung.Otherwise, the safety filament s only comes into effect automatically after the normal filament has burned through.
