PURPOSE:To easily exchange a fluorescent tube with another one and to constitute the tube in a simple structure having an excellent impact resistance so that the tube can be surely conducted by mounting a connector on a circuit board mounted with lead wires for conducting the tube and interposing elastic members between the circuit board and connectors. CONSTITUTION:A fluorescence tube 1 fitted to a fluorescence tube fitting circuit board 4 by means of fixing cushions 3 and soldering lead wires 2 for conduction is held in a fluorescence tube housing section provided between an upper enclosure 6 and lower enclosure 7. When the cushions 3 are made of a certain material having a some degree of softness such as silicone rubber and designed so that the cushions 3 can have an interference when the tube 1 is held between the enclosures 6 and 7, the tube 1 can be more surely held. In addition, when the tube 1 is mounted by giving some length margins to the lead wires 2, impacts to the tube 1 can be relieved. A connector 5 is provided so that the tube 1 can be easily exchanged with another one. |
