Abstract
The invention relates to an electrode for a discharge lamp, wherein the electrode has a base body having an electrode plateau providing an end face of the electrode, wherein the base body is delimited by the electrode plateau in a longitudinal extension direction of the electrode. Furthermore, the electrode has a coating, arranged in at least a first region of the base body that is different from the electrode plateau, to increase an emission of heat. In addition, the electrode has an at least partially contiguous free region of the base body extending at least partly in the longitudinal extension direction as far as the electrode plateau, in which the coating for increasing the emission of heat is not arranged, and wherein the first region adjoins at least one section of the free region in the circumferential direction of the electrode.
