Abstract: Disclosed are a process for fixing a filament onto a support in an incandescent lamp in which the filament is prevented from being deformed when it is welded onto a support and also a filament supporting structure to be established by the process. The filament fixing process comprises wrapping a foil body around each supporting end portion of a filament; squeezing the wrapped foil body together at positions close to each end thereof to form a cylindrical portion and a fin-like portion protruding from the cylindrical portion; and welding the cylindrical portion onto a support (e.g. a support wire or a supporting piece of a shade) for the filament such that the fin-like portion of the foil body may be situated within the distance or range corresponding to the diameter of the cylindrical portion as measured from the surface of the support.

Abstract: An electric discharge lamp comprising a tubular lighttransmitting envelope of alumina ceramic closed at each end by refractory metal end caps. The envelope contains a discharge sustaining filling and electrodes supported by the end caps. At least one end cap is a thin-walled metal thimble having a skirt portion sealed to the end of the tube and a central blind teat in which the electrode shank is seized. The need for critical welding or brazing to the end cap is thereby avoided.
