Abstract:
A high-pressure discharge lamp having an ignition aid may be provided, having a discharge vessel that is surrounded by gas, wherein the discharge vessel includes two ends having fusings in which electrodes are secured, wherein an ignition aid is fastened on at least one fusing, wherein the ignition aid has a local field amplifier in the form of a tip or a curved part, wherein the ignition aid is configured to cause a corona discharge in the surrounding gas which emits UV radiation into the discharge vessel.
