Abstract
Device comprising a gaseous discharge lamp with a thermionic cathode emitting radiation from the positive column, the lamp containing, apart from a rare gas, at least two volatile metals, at least one of which is an alkali metal, characterized in that the two volatile metals are provided in the form of an alloy and that the wall temperature under the operating conditions of the lamp is chosen so that the constituent of the alloy having the lowest ionization potential in the place of the positive column is ionized at least 20% on average in the cross-sectional area of the lamp, the density of the constituent of the highest ionization potential having a favorable value for the generation of radiation and the pressure of the rare gas being of the order of 0.1 to 10 Torr.
