Abstract

A discharge lamp of the short arc type which has an arc tube in which there is a pair of opposed electrodes, a pair of hermetically sealing parts which extend outward from opposite ends of the arc tube, and a trigger wire, each end of which is wound around one of the hermetically sealing parts, with a middle area of the trigger wire running along the outside surface of the arc tube. In the area of at least one of the ends of the trigger wire, a bend is formed which comes to rest on one of the hermetically sealing parts, and following this bend, a fold is formed at the outer end area of the end of the trigger wire.

Description

technical field [0001] The present invention relates to a short-arc discharge lamp containing xenon gas used as a light source for a projector, or a short-arc discharge lamp containing mercury used as a light source for semiconductor exposure, for example. Background technique [0002] For short-arc discharge lamps, trigger wires are usually arranged on the outer surface of the luminous tube in order to reduce the breakdown voltage. [0003] In Japanese Patent Laid-Open No. 51-78586, as a method of fixing the trigger wire to the lamp, it is disclosed that the trigger wire is wound once in a sealed tube connected to both ends of the luminous tube, and the trigger wire is twisted and rotated once with a tool. End-to-end technology. [0004] In addition, JP-A-2002-367566 discloses the following technique of processing elastic metal wires such as stainless steel into a bow shape in accordance with the shape of the arc tube, and springs matching the diameter of the sealing tube ...
