摘要

An electrode device for gas discharge lamps, in particular for low pressure mercury vapor discharge lamps, consisting of a support and an emitter material supported thereon, the support being constituted by a current wire that it has a circular cross section and is surrounded by a large number of turns of a comparatively fine overwinding yarn, the surface comprised within the cross section of the turns of the overwind yarn being larger than the cross-sectional area of the yarn of current, characterized in that at least 90% of the number of turns of the overwinding yarn is coupled to the current wire at an angle of at least 160º of the cross section of the current wire.
