<P>PROBLEM TO BE SOLVED: To provide a fluorescent lamp securing a sufficient insulation distance between lead wires, excellent in assembling property. <P>SOLUTION: The fluorescent lamp 1 is composed of an arc tube 2 and a cover body 3. In four bent bulbs constructing a part of the arc tube 2, respective filament electrodes 26 are sealed on both end parts of a discharging path. A set of lead wires 27 of which the other ends are drawn out from the bent bulb 2 are connected to both ends of respective filament electrodes 26. The other ends of the lead wires 27 are connected to respective four bulb base pins 34. The direction of virtual line A connecting all the four bulb base pins 34 and the longitudinal direction of the filament electrodes 26 are almost parallel with each other. Further, the direction of virtual line A connecting all the four bulb base pins 34 and the direction of virtual line B connecting central lines of straight tube parts 21a in which the filament electrodes 26 are sealed, are almost parallel with each other. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
