PURPOSE:To simplify a wiring work with plural discharge tubes lit with a lighting device, and weight and wiring space as a lighting device decreased by providing control means in which plural switching means can be individually switched to a lighting device. CONSTITUTION:A stabilizer 2 is constantly operated by a power source 1 with the stabilizer 2 and a power source device 4 built in a microcomputer 3 as control means are connected to a AC power source 1 of a lighting device. A common line C of the stabilizer 2 is connected to an end of each switching means 5a-5h of a switching part 5. And load lines A1-A8 individually connected to other ends of switching means 5a-5h are connected to load lines B1-B8 of the stabilizer 2 via fluorescent discharge tubes L1-L8. And output terminals P1-P8 of an output port 6 in a computer 3 are connected to each input terminal of switching means 5a-5h with signal lines D1-D8, and the port 6 is operated with a control device 7. |
