Description

Elektrische Glimmlichtlampe für niedrige Spannungen, bei der das negative Glimmlicht leuchtet. Die Erfindung! betrifft eine elektrische Gas-Lampe, bei welcher das negative Glimmlicht zur Lichterzeugung nutzbar gemacht wird. Im Gegensatz zu den bisher bekannten Lampen dieser Art werden nach der Erfindung lange Röhren mit entsprechend langen Kathoden, welche die Röhren der Länge nach durchziehen, verwendet. Es gelingt auf diese Weise, Röhren von beträchtlicher Länge mit den üblichen Spannungen der Lichtleitungen zu betreiben, insbesondere wenn zur Füllung Ed'eligas verwendet wird, und wenn gleichzeitig ,durch entsprechende Anordnung der Anode dafür gesorgt wird, daß der Kathodenfall nicht oder nur in geringem, Grade anormal wird. Zu diesem Zweck durchzieht entweder auch die Anode die Röhre der ganzen Länge nach in geringem Abstand von der Kathode, oder es werden längs der Röhre mehrere Anoden, welche außerhalb derselben elektrisch leitend verbunden sind, in regelmäßigen Zwischenräumen eingeführt. Unter Umständen kann man geeignete Widerstände in die einzelnen Anodenzweige einschalten. Die Elektroden können .n an sich bekannter Weise netzförmlig sein, z. B. aus gestricktem: ZVletalld'raht bestehen. Sie können in der Röhre ausgespannt sein oder in Form eines langen Schlauches aus -Metallnetz der Röhrenwand. anliegen. In letzterem: Fall durchzieht die Anode als achsialer Draht die Röhre und die Kathode. Die Stromlzuführungen für die Kathode und Anode können entweder an demselben Ende der Röhre oder an entgegengesetzten Enden derselben die Wand durchsetzen. Die Röhre wird dementsprechend entweder mit einem oder mit zwei Sockeln versehen.Electric neon lamp for low voltages where the negative Glow light shines. The invention! relates to an electric gas lamp in which the negative glow light is made usable to generate light. In contrast to the previously known lamps of this type are long tubes according to the invention Correspondingly long cathodes, which run through the length of the tubes, are used. In this way it is possible to produce tubes of considerable length with the usual voltages to operate the light pipes, especially if Ed'eligas is used for filling is ensured, and if at the same time, by appropriate arrangement of the anode it becomes that the cathode fall is not or only slightly abnormal. To this Purpose either the anode runs through the whole length of the tube to a small extent Distance from the cathode, or there are several anodes along the tube, which are outside the same are electrically conductively connected, introduced at regular intervals. Under certain circumstances, suitable resistors can be switched on in the individual anode branches. The electrodes can be net-shaped .n in a manner known per se, e.g. B. made of knitted: ZVletalld'raht exist. They can be stretched out in the tube or in the form of a long hose made of metal mesh of the tube wall. issue. In the latter: case pulls through the anode as an axial wire the tube and the cathode. The power supply for the cathode and anode can either be at the same end of the tube or at opposite ends The ends of the same penetrate the wall. The tube is accordingly either with one or two bases.
