Electrode assembly and lamp with conductor foil

摘要

This invention relates to an electrode assembly for a sealed lamp envelope. The electrode assembly comprises an outer lead wire and an inner lead wire, providing electric connection to an electrode in the envelope. A substantially planar conductor foil connects the outer lead wire and the inner lead wire. The conductor foil provides a sealed electric connection through a sealed portion of the envelope. In order to improve the mechanical stiffness of the conductor foil, the conductor foil comprises a curvature. The curvature is formed by the foil in a plane substantially perpendicular to a line connecting the outer lead wire and the inner lead wire. There is provided a lamp with the electrode assembly and a method for stiffening a conductor foil of an electrode assembly of a sealed lamp envelope.
