HIGH-PRESSURE DISCHARGE LAMP HAVING AN IGNITION AID

摘要

The invention relates to a high-pressure discharge lamp having an ignition aid and comprising a discharge vessel, which is accommodated in an outer bulb. The ignition aid is a UV enhancer having a can-like container (12), which has an inner electrode (18). At least part of the end-face edge of the inner electrode at least comes close to the end face (24) of the container (12). An external electrode is attached to the outside of the container.

主权项

1. A high-pressure discharge lamp having an ignition aid, comprising a discharge vessel which is fitted in an outer bulb, wherein a UV enhancer is fitted as an ignition aid in the outer bulb, wherein the UV enhancer comprises a UV-transparent can-like container having an inner wall and end side and longitudinal axis, the container enclosing with its inner wall a cavity which is filled with a gas that can emit UV radiation, wherein an inner foil-like electrode, which has an end-side edge, is fitted in the cavity in such a way that at least part of the end-side edge at least lies close to the end side of the container, and wherein an external electrode is applied externally in the vicinity of the container.
