METHOD FOR MANUFACTURING A CONDUCTIVE CONNECTION OF A METALLIC ELECTRODE WIRE AND A METALLIC LEAD-IN WIRE

摘要

This invention describes a method for manufacturing a conductive connection of a metallic electrode wire (1) and a metallic lead-in wire (3) for a gas discharge lamp (11), preferably a ceramic discharge metal halide lamp. The method includes a bending step, whereby an end portion (4) of the lead-in wire (3) is bended and folded over such that a first section (15) of the end portion (4) at the tip of the lead-in wire (3) overlaps a second section (16) of the end portion (4). Furthermore, the method includes the placement of the electrode wire (1) in-between the first section (15) and the second section (16) of the folded-over end portion (4) of the lead-in wire (3). Finally, a connection is formed between the electrode wire (1) and the lead-in wire (3) by stamping at least parts of the folded-over end portion (4) of the lead-in wire (3) while heating at least a part of the lead-in wire (3) such that the first section (15) and the second section (16) of the folded-over end portion (4) are at least partially touching a portion of the electrode wire (1). Furthermore, the invention describes a gas discharge lamp (11), comprising a conductive connection of a metallic electrode wire (1) and a metallic lead- in wire (3) and a corresponding manufacturing system (50).
