  • Patent number: 7394189
    Abstract: An objective is to provide a compact self-ballasted fluorescent lamp which can reduce occurrence of a short circuit without protecting lead wires extending from each end portion of a spiral arc tube. To achieve the objective, a pair of connection pins is provided on a circuit board of the compact self-ballasted fluorescent lamp, near a periphery of the circuit board so as to oppose another pair of connection pins formed near the periphery. In this way, the pairs of connection pins can be respectively provided directly above the end portions of the spiral arc tube. Thus, lead wires extending from each of the end portions can be connected to a corresponding one of the pairs of connection pins with a relatively short distance. This prevents the lead wires from being in contact with the circuit board, thereby reducing occurrence of a short circuit.

    Abstract: An arc tube is formed by a glass tube that is turned at a substantially middle thereof and wound around a spiral axis from the middle, to have a double-spiral structure. End portions of the arc tub are wound around the spiral axis. A holder has insertion openings formed therein in such shapes that correspond to shapes of the ends of the arc tube. The insertion openings allow the ends of the arc tube to be inserted along a bottom wall of the holder. The holder also includes guide grooves provided in the areas before the insertion openings in the spiral direction of the ends of the arc tube. The guide grooves allow the end portions of the arc tube to come in contact, and when the arc tube is rotated around the axis, guide the ends of the arc tube to the insertion openings.

  • Patent number: 7253556
    Abstract: A lamp for a light string has a mechanical shunt to allow current to pass to the next light in the event of a missing bulb. A resilient shunt is held in a generally lateral orientation by a shunt holder within the socket. When the hollow base with its bottom opening is inserted into the socket, the walls of the base cam the ends of the shunt away from the electrical contacts on the walls of the socket. Likewise, when the base is removed, the resilient lateral ends of the shunt return to engage the electrical contacts. The timing of the contact by the shunt with the electrical contacts avoids arcing. Additionally, slits formed in the wall of the base allows the Dumet wires to exit the sides of the base in the correct location for engaging the electrical contacts, thus reducing the instances of misaligned Dumet wires.
