Abstract

Eine Elektrode (35) für metalldampfhaltige Entladungslampen besteht aus hochschmelzendem, elektrisch leitendem Material, bevorzugt aus Wolfram oder einem Material, das Wolfram überwiegend enthält; sie besteht aus einem Schaft (36) mit einem stiftförmigen Kopfteil (37), der eine Längsachse L definiert, wobei im Bereich des Kopfteils (37) mindestens eine Bohrung (39) im wesentlichen quer zur Längsachse, insbesondere in einem Winkel von 60 bis 90° zur Längsachse, angeordnet ist.
