<P>PROBLEM TO BE SOLVED: To provide an illumination tube in which each of lighting fixtures can be switched on and off without operating a switch on a wall face and, further, other illumination tube of multiple-lamp type lighting fixtures can be switched on and off. <P>SOLUTION: The straight-tube type illumination tube 1 which is installed as one lamp of the multiple-lamp type straight-tube type illumination fixture has a switch means 6 that switches over a wiring (wiring W2) to light up all the lamps installed on the straight-tube type illumination fixture, a wiring (wiring W1) which lights up other straight-tube type illumination tubes, and a wiring (wiring W3) which switches off all the lamps. Since the switch means 6 is formed of a rotary switch SW1, switching can be operated smoothly in order from the wiring W1 to the wiring W3 and again to the wiring W1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
