Abstract: 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.

Abstract: An incandescent lamp for use in a reflector is provided. The lamp has an envelope having a longitudinal axis, at least one filament, and electrical lead-out wires. A metal support portion receives the envelope and a sleeved metal optical disc positions the filaments with respect to the reflector in a plane perpendicular to the longitudinal axis. The incandescent lamp has a plastic base anchoring the sleeved optical disc and including the electrical lead-out wires. A locking element, which is not separately formed, is used.
