    Abstract: PROBLEM TO BE SOLVED: To provide an electrode member capable of fully ensuring bond strength between a cup electrode having a bottomed cylindrical shape of tungsten or molybdenum and a sealing material by resistance welding and a cold cathode fluorescent lamp having this member.
    SOLUTION: The electrode member comprises a cup electrode 6 having a bottomed cylindrical shape of tungsten or molybdenum, a sealing material of tungsten or molybdenum connected to an outside end face on the bottom side of the cup electrode 6 by welding, and a metal layer 7, having low melting-point, that melts between the outside end face of the cup electrode 6 and the sealing material 4 during welding. Since the cup electrode 6 is welded to the sealing material 4 via the metal layer 7 having low melting point, welding can be performed at relatively low temperature, so that ample bonding strength is ensured by resistance welding.

    Abstract: PROBLEM TO BE SOLVED: To provide a compact self-ballasted fluorescent lamp and an illumination fixture capable of suppressing a failure accompanying an abnormal temperature rise of a filament electrode at the end of life of the fluorescent lamp.
    SOLUTION: In the lamp, the filament main wire diameter made as to be ≤7 mg/20 cm so that a cold resistance of a lead wire in the range of 20°C to 25°C is ≤8Ω, thereby at the end of life, when an electron radiation substance has run out and the filament is overheated, the filament is comparatively easily disconnected and a lamp current does not flow, thereby an action of an inverter circuit is stopped.

    Abstract: PROBLEM TO BE SOLVED: To provide a synchronous switching device for making a plane fluorescent lamp emit light, at a rear face of a large-screen liquid crystal display (LCD) panel. SOLUTION: The synchronous switching device is provided with a common electrode 308, distribution electrodes 310, potential transformers 312, and a signal generator 314. The distribution electrodes are aligned linearly face to face with the common electrode. Each distribution electrode is shorter than the common electrode. Each potential transformer is electrically connected with the common electrode and one of the distribution electrodes. All the potential transformers are electrically connected with the signal generator. A first panel 102a, a second panel 102b and two side panels 102c form a plane lamp 100 having a hollow space inside. The distribution electrodes and the common electrode are fitted at each side of the hollow space. The planar fluorescent lamp emits light through high-voltage synchronous signals generated by the signal generator and the potential transformers. COPYRIGHT: (C)2006,JPO&NCIPI
