  • Patent number: 5666021
    Abstract: A lamp holder includes a base and two electrical contacts for forming a connection with a bulb having an envelope around an electrical filament having two wires extending therefrom. Each wire forms a loop protruding from the envelope, the two loops being at opposed ends of the envelope. Each electrical contact of the lamp holder has a wire with a hook at its free end and formed to engage one of the two loops of the bulb, so that a shorter one of the wires engages the one of said two loops at the nearer end of the bulb and the other larger spring wire engages the other of said two loops at the far end of the bulb, in a manner that induces a spring tension in the wire. Thus, the bulb is held suspended between, and in electrical contact with, the two loops.

  • Patent number: 5562481
    Abstract: This invention relates to a festoon lamp holder, and to a lighting system incorporating such a lamp holder. The lamp holder comprises a molded cap and base, and forms a pressure-tight seal with the supply cable, and a water-tight seal with a removably attached globe. Between the cap and base, lugs with detents engage within a groove, and through a camming action on a tapered post, engage permanently with a retaining means, thereby locking the detents within the groove. Probes between the cap and base pierce the cable, which may be used to support the lamp holder in a festoon lighting system. The lamp may be a low voltage halogen lamp and may also be formed as a festoon bulb held perpendicular to the lamp holder by hooked wires.

  • Patent number: 5161881
    Abstract: A festoon lamp holder has a base provided with recesses either side of probes. A cap permanently fits to the base to provide a water-tight seal with an electrical cable passing in use through the holder. Power is provided from the cable conductors via feed-throughs for a bulb. A globe surrounds the bulb and provided with seals forms a gas-tight chanber for the bulb.
