Scheinwerferbogenlampe mit einer positiven Reinkohlen-Elektrode.Headlight arc lamp with a positive pure carbon electrode.

Patentiert im Deutschen Reiche vom 18. Februar 1917 ab.Patented in the German Empire on February 18, 1917.

Die Erfindung betrifft eine Bogenlampe für Scheinwerfer und besteht darin, daß die positive Elektrode aus Reinkohle kleineren Durchmessers gemacht wird, als der. der angewandten Betriebsstromstärke entsprechende normale Kraterdurchmesser beträgt. Hierbei wird erreicht, daß die ganze Spitze der Elektrode und auch die ihr benachbarten Teile der zylindrischen Begrenzungswand der Kohlen licht-1 ausstrahlend wirken und die Vervielfältigungszahl zwischen Krater und Spiegelfläche und The invention relates to an arc lamp for headlights and consists in that the positive electrode is made of pure carbon of a smaller diameter than that. the normal crater diameter corresponding to the applied operating current. Here, it is achieved that the whole tip of the electrode and the adjacent parts of their cylindrical boundary wall of the coals light- emitting function 1 and the reproduction number from craters and mirror surface and

somit die Leuchtkraft des Scheinwerfers erhöht wird.thus the luminosity of the headlight is increased.
