  • Electric lamp with a torpedo shaped conductor tip
    Patent number: 4101798
    Abstract: External cylindrical current conductors of an electric lamp are torpedo-shaped at the end which is welded to a metal foil in a pinch seal of the lamp vessel.The torpedo-shaped part has a length which is at least equal to the diameter of the cylindrical part, while the diameter of the torpedo-shaped part at a distance from the cylindrical part of 0.9 times the cylinder diameter is at most equal to half the cylinder diameter.Also when comparatively thick external current conductors, approximately 1.5mm diameter, are used and at a high temperature of the pinch seal, the lamps will withstand cracking. The welded joint of the conductors to the metal foil is stronger than in known lamps.

  • Incandescent lamp-reflector unit
    Patent number: 4081708
    Abstract: An incandescent lamp-reflector unit having a metal reflector in which, for increasing the reflecting surface, the neck aperture of the reflector is maintained as small as possible, is not flash-over-safe due to the small distance between bare parts of the neck of the reflector and the contact pins of the lamp. The unsafety is removed by causing the said distance to be larger than the smallest distance of the pins and the neck of the reflector by means of an insulating envelope of the pins and/or an insulating coating on and near the end face of the neck of the reflector.

  • Infrared lamp with heat conductive cap assembly and fixture
    Patent number: 4069437
    Abstract: An infrared tubular incandescent lamp provided with a cap assembly and current supply lead at each pinched end of the lamp vessel. The caps are not electrically conductive and are heat sinks. Each cap assembly includes a formed ceramic member enclosed by a cap with a good heat conductive mass embedded between each pinched lamp seal and its surrounding metal cap. A luminaire for this lamp is provided which contains means resiliently engaging the lamp cap so as to form a heat sink.

  • Electric lamp
    Patent number: 3991337
    Abstract: Outer molybdenum current conductors of electric lamps having quartz glass lamp envelopes and pinched seals have a corrosion-resistant metal coating. The current conductors have been ground bare at the end which is welded to a molybdenum foil incorporated in the pinched seal.As a result of this it is achieved that the current conductors do not corrode, that the welding electrode upon making the connection to the foil does not stick to the coating, and that upon making the pinched seal the electric contact between the foil and the current conductor is not interrupted.
