Description
Bogenlampenelektrode, Gegenstand der Erfindung ist eine Bogenlampenelektrode in Verwendung als Anode bei Hochleistungsscheinwerfern, bei welcher in bekannter Weise die innerste Schicht, der Docht, den Leuchtzusatz in Form von Metallsalz, -karbid, -pulver als Metallader o. dgl. enthält, während die übrige Dochtmasse ganz oder teilweise aus Graphit besteht und der Docht von einem Graphitrohr, das die äußerste Schicht der Elektrode bildet, umschlossen wird.Arc lamp electrode, the invention relates to an arc lamp electrode in use as an anode in high-performance headlights, in which in well-known Wise the innermost layer, the wick, the luminous additive in the form of metal salt, -carbide, -powder as a metal vein or the like. Contains, while the rest of the wick mass is whole or partially made of graphite and the wick of a graphite tube that the outermost layer of the electrode forms, is enclosed.
Das Neuartige der Elektrode besteht darin, daß zwischen dem Docht und dem Graphitrohr eine schwach gebrannte Reinkohleschicht angeordnet ist.The novelty of the electrode is that between the wick and a lightly burned pure carbon layer is arranged on the graphite tube.
Durch Versuche ist gefunden worden, daß solche Elektroden sich besonders eignen für die Verwendung in Hochleistungsscheinwerfern, vor allem als Anoden. Die Elektroden solcher Scheinwerfer werden mit sehr hoher Stromdichte betrieben. Die neue Elektrode zeigt bei dieser Betriebsweise neben dem verhältnismäßig geringen Spannungsabfall, der dem hohen Graphitgehalt zu danken ist, eine günstige und zeitlich beständige Ausbildung. des Brennendes und als Folge dieses Verhaltens ruhiges Licht.It has been found through experiments that such electrodes are particularly useful suitable for use in high-performance headlights, especially as anodes. the Electrodes of such headlights are operated with a very high current density. the new electrode shows in this mode of operation in addition to the relatively low The voltage drop, which is due to the high graphite content, is favorable and timely constant training. of the burning and as a result of this behavior calm light.
