<p>PURPOSE:To prevent misuse of a device and shortness of a stabilizer life by providing a power supply negative electrode common terminal, power supply positive electrode first terminal corresponding to the specific first frequency and a power supply positive electrode second terminal corresponding to the specific second frequency. CONSTITUTION:A discharge lamp stabilizer 10 is provided with a power supply negative electrode common terminal P0, power supply positive electrode first terminal P1 corresponding to the specific first frequency (50Hz) and a power supply positive electrode second terminal P2 corresponding to the specific second frequency (60Hz). The stabilizer side first connecting fixture 21, having a pair of electrodes B11, B13 wired respectively to the power supply negative electrode common terminal PO and the power supply positive electrode first terminal P1, and the stabilizer side second connecting fixture 22, having a pair of electrodes B21, B22 respectively wired to the power supply negative electrode common terminal P0 and the power supply positive electrode second terminal P2, are provided. On the other hand, a power supply side connecting fixture, effectively connected only to either one of the stabilizer side first or second connecting fixture suited for a power supply frequency, is provided in a power supply side. In this way, possibility of misuse is decreased, so that shortness of life of stabilizer can be prevented.</p> |
