Patent ID: 8368304

Claim:
A discharge lamp comprising: a lamp vessel that includes a discharge vessel, the lamp vessel enclosing a discharge medium and including two lamp shafts each extending coaxially at opposite ends of the discharge vessel, two outer power-feed sections, each extending outwardly from inside the two lamp shafts respectively, two electrodes, each consisting of an electrode rod and electrode head, with the electrode rods being arranged along the lamp shafts such that the two electrode heads are located radially opposite one another inside the discharge vessel, a sealed section in each of the two lamp shafts by which a gas-tight electricity passage is formed between the two outer power-feed sections on the one hand and the two electrodes on the other, a narrow section in each of the two lamp shafts that is arranged between the respective sealed section and the electrode head of the associated electrode, with the narrow section closely surrounding the electrode rod; and a damping/guiding element arranged between the narrow section of a lamp shaft and the electrode rod of at least one electrode, wherein the damping/guiding element is embodied as at least hybrid bearing wire helix arranged on the electrode rod within a part of the narrow section, wherein the hybrid bearing wire helix comprises a securing winding located on the end of the narrow section farthest from the electrode head and a plurality of damping windings.
