   <EMI ID=1.1> 

  
L'Invention consiste en une lampe.. incandescence à remplissage de gaz, dont les avantages par rapport aux lampes connues sont que la lampe ne s'échauffe que faiblement, qu'elle possède une grande intensité lumineuse et une forte résistance du fil. incandescent, ce qui rend la lampe durable, facilement transportable) résistante aux vibrations et ayant.de plus un effet d'ombres avantageux*

  
La caractéristique de l'invention est que ses fils incandescents sont tordus ensemble de plusieurs fils en forme de corde et ces fils tordus sont enroulés en spirale, lesquels fils enroulés sont disposés en forme de coin de telle manière que l'une des extrémités est fixée à un fil de support commun moyen, son autre extrémité cependant étant fixée à des supports séparés qui sont disposés autour du support commun, à la manière d'une croix.

  
Dans le dessin ci-joint, on a montré à titre d'exemple la lampe à incandescence faisant l'objet de l'invention en trois modes de réalisation*

The invention consists of a gas-filled incandescent lamp, the advantages of which over known lamps are that the lamp heats up only slightly, that it has a high luminous intensity and a high wire resistance. incandescent, which makes the lamp durable, easily transportable) resistant to vibrations and also having an advantageous shadow effect *

  
The feature of the invention is that its glowing threads are twisted together by several cord-like threads and these twisted threads are wound in a spiral, which wound threads are arranged in a wedge-shape such that one of the ends is fixed. to an average common support wire, its other end however being attached to separate supports which are arranged around the common support, in the manner of a cross.

  
In the attached drawing, the incandescent lamp forming the subject of the invention has been shown by way of example in three embodiments *
