Abstract
In various embodiments, a discharge lamp may include a lamp vessel that includes a discharge vessel enclosing a discharge medium and two lamp shafts each extending coaxially at opposite ends of the discharge vessel, two outer power-feed sections each extending to the outside from one of the lamp shafts, 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 mutually opposite 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.
