High-pressure discharge lamp having a capacitive ignition aid
First Claim
1. A high-pressure discharge lamp having an ignition aid, having a discharge vessel that is surrounded by gas, wherein the discharge vessel comprises 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,wherein the ignition aid is a clip which has a frame part with four sides and which is positioned on the fusing and surrounds this at least partially, wherein at least one tip extends inwardly from the frame part and in the mounted state points in the direction of the discharge volume.
