ABSTRACT:
The high pressure discharge lamp has electrodes which each have a wrapping of tungsten wire near the tip of the electrode rod. The electrode rod has unround cross-sections, formed by indentations and bulges. The tungsten wire, wrapped around the electrode rod, is in substantially circumferential contact with the unround cross-sections, thereby keeping the wire fixed to the rod.
