In various embodiments, a gas discharge tube having a starting aid may include a discharge vessel with at least one open end, in which end a stopper with a continuous stopper bore is inserted; and an electrical leadthrough, which is inserted into the respective stopper bore and is fuse-sealed into the stopper bore. The starting aid extends as far as into the stopper bore.

Gas discharge tube including a starting aid

In a high-pressure discharge lamp including a ceramic discharge vessel, a secure connection between a hybrid antenna as starting aid and a leadthrough of the discharge vessel is provided by virtue of the fact that a means between leadthrough and extension limits the ohmic resistance between leadthrough and hybrid antenna preferably to at most 100&#x3a9;.

An evaluation device for measuring the ignition energy of a discharge lamp that is ignited by means of a superposed ignition unit, with the aid of a measuring signal that is proportional to the voltage across the discharge, and a measuring signal that is proportional to the current flowing through the lamp, is provided. The evaluation device is configured such that the energy injected into a discharge lamp during a high voltage pulse is suitably evaluated by means of a combination of an analog circuit and a digital circuit.
