Abstract (en)
[origin: WO2009039880A1] The invention relates to a direct-current discharge lamp comprising an anode (10) and a cathode (12) disposed across from one another at a predetermined distance (r) inside a discharge vessel (14) filled with a filling gas, wherein electrical power (P) may be applied to the anode (10) and cathode (12) in order to produce a gas discharge, wherein at least the distance (r) between the anode (10) and cathode (12), the electrical power (P), and a geometry of the anode (10) are adapted to one another such that, in the heated state of the direct-current discharge lamp, a region (22) of a surface (24) of the anode (10) facing the cathode (12) is free flowing.
