<P>PROBLEM TO BE SOLVED: To provide a fluorescent lamp having a easily manufacturable and highly reliable structure while maintaining compact property and capable of greatly reducing starting voltage. <P>SOLUTION: An arc tube 2 comprises a glass tube 6 wherein two U-shaped tubes 2f wherein straight tubes 2a, 2b are connected with a bridge part 2e are connected with a bridge part 2g in parallel and electrodes 4, 5 provided at both end parts of the glass tube 6, forms a discharge path crooked inside. A base case 3 is provided with a power-feeding member 10 which holds the arc tube 2 and is a tube pin. A coiled proximity conductor 8 is provided in a thin tube 7c of the arc tube 2. One end part of the coiled proximity conductor 8 is connected with one lead wire 9 of the electrode 4, and the other end part is connected with a power-feeding member 10 through a conducting wire 14. The other lead wire 11 of the electrode 4 and lead wires 12, 13 of the electrode 5 are directly connected with the other power-feeding member 10, respectively. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
