Description

Elektrische Lampen für Gruben oder andere mit entzündlichen Gasen oder Dämpfen erfüllte Räume. Gegenstand der Erfindung ist eine elektrische Lampe, welche vornehmlich als Richt-oder Signallampe in Bergwerken, explosionsgefährlichen Räumen usw. dienen soll. Der Hauptvorzug der Lampe besteht darin, daß sie keine glühenden Körper enthält und der Leitvorgang in der Lampe bei Eintritt geringster Spuren der umgebenden Atmosphäre ohne Nachglühen sofort aufhört. Wenn also eine derartige Lampe in einer entzündlichen Atmosphäre, beispielsweise in Kohlengruben, brennend zertrümmert wird, so besteht keinerlei Gefahr, daß die eindringenden Gase sich an der Lampe entzünden.Electric lamps for pits or others with flammable gases or steaming filled rooms. The invention relates to an electric lamp, which are primarily used as a directional or signal lamp in mines, potentially explosive Rooms etc. should serve. The main advantage of the lamp is that it does not have any Contains glowing bodies and the conducting process in the lamp is slightest when it enters Traces of the surrounding atmosphere without afterglow ceases immediately. So if a such a lamp in a flammable atmosphere, for example in coal mines, is smashed while burning, there is no risk of the penetrating gases ignite on the lamp.

Die Lampe, welche die vorbeschriebenen Eigenschaften besitzt, ist eine elektrische Gaslampe, in weicher ein mehr oder weniger verdünntes Gas durch eine elektrische Entladung zum Leuchten gebracht wird und in welcher der Widerstand der Entladungsbahn schon durch geringe Spureh von. Fremdgasen so weit erhöht wird, daß die Lampe erlischt. Der Leitvorgang hört in diesem Falle augenblick lieh auf; durch Versuche wurde festgestellt, daß die in die stromdurchflossene Entladungsbahn eindringenden entzündlichen Gase nicht gezündet werden können, da die Ionisation des Füllgases der Lampe zu schnell vernichtet: wird. - Selbstverständlich muß die Lampe so ausgebildet sein, daß ° sich bei Bruch oder Zertrilmmerung derselben die Elektroden oder die Zuleitungen innerhalb derselben nicht berühren und dadurch zur Entstehung von Zündfunken Anlaß geben können.The lamp which has the properties described above is an electric gas lamp, in which a more or less diluted gas passes through an electrical discharge is made to glow and in which the resistance of the discharge path by a slight trace of. Foreign gases is increased so much, that the lamp goes out. In this case, the guiding process ceases instantly; Experiments have shown that the current-carrying discharge path penetrating flammable gases cannot be ignited because of the ionization of the filling gas of the lamp destroyed too quickly: is. - Of course she has to Lamp be designed so that ° in the event of breakage or shattering of the same Do not touch the electrodes or the leads within them and thereby lead to the The formation of ignition sparks can give rise to.
