  Elektrische Glimmlampe. 



   Die Erfindung betrifft eine mit einem Gemisch von Neon und Helium gefüllte Glimmlichtlampe. Nach der Erfindung lässt sich die Lichtausbeute einer solchen   GIimmlicht) am]) e   wesentlich steigern, wenn man zur Füllung der Lampe Gemische von Neon und Helium verwendet. welche reich an Helium sind. Bisher ist man bei Verwendung solcher Gemische über   30"/Helium   nicht hinausgegangen. Es hat sich jedoch gezeigt, dass schon eine Steigerung des Heliumgehaltes über   30"/genügt,   um eine wesentliche Steigerung der Lichtausstrahlung zu erzielen, die jedoch bei einem bestimmten Prozentsatz von Helium ein Maximum erreicht, welches ausser von der Konstruktion der Lampe im wesentlichen von dem gesamten Gasdruck derselben abhängig ist.

   Bei einem Gasdruck von etwa 10   mem   Quecksilbersäule liegt das   Ökonomiemaximum   bei einer Mischung von 25% Neon und 75% Helium. Es gelingt so, ungefähr die doppelte Lichtausbeute zu erhalten wie bei reinem Neon. 



   PATENT-ANSPRÜCHE : 
1. Elektrische Glimmlampe mit einer aus einem Gemisch von Neon und Helium bestehenden   Füllung.   dadurch gekennzeichnet, dass der Gehalt an Helium mehr als 30% der gesamten Füllungsmenge   beträgt.

  Electric glow lamp.



   The invention relates to a glow lamp filled with a mixture of neon and helium. According to the invention, the light yield of such a glowing light can be increased significantly if mixtures of neon and helium are used to fill the lamp. which are rich in helium. So far one has not gone beyond 30 "/ helium when using such mixtures. However, it has been shown that an increase in the helium content above 30" is sufficient to achieve a significant increase in the light emission, but with a certain percentage of helium reaches a maximum which, apart from the construction of the lamp, is essentially dependent on the total gas pressure of the same.

   At a gas pressure of around 10 mm of mercury, the economic maximum is a mixture of 25% neon and 75% helium. In this way, it is possible to obtain roughly twice the light output as with pure neon.



   PATENT CLAIMS:
1. Electric glow lamp with a filling consisting of a mixture of neon and helium. characterized in that the helium content is more than 30% of the total filling amount.
