Abstract

Die Glühlampe ist ausgestattet mit einem Leuchtkörper (5), der zusammen mit einer Füllung in einem Kolben (1) vakuumdicht eingebracht ist, wobei der Leuchtkörper (5) ein Metallcarbid aufweist, dessen Schmelzpunkt oberhalb dem von Wolfram liegt. Die Stromzuführung (3) ist integral mit dem Leuchtkörper (5) aus einem Draht gefertigt und mit einem elektrisch leitenden Überzug (7) versehen, der die Stoßfestigkeit und Einschaltfestigkeit entscheidend verbessert.
