Abstract

"Electrode device covered with electron-emitting material for gas discharge lamps ignited by means of an incandescent discharge, more particularly for high-pressure mercury vapor discharge lamps, comprising a spiral of tungsten wire wound around, and supported by a central core wire, the core wire protruding from the spiral on the discharge side, characterized in that the tungsten spiral comprises a strand of at least two twisted tungsten wires with a diameter that is small with respect to the of the core wire.
