The leakage detecting circuit 311 is composed of a zero current transformer (ZCT) circuit for detecting a short circuit by using an electric voltage sum of the LEDs 400 supplied with a current from a power supply (not shown).

The dimming control unit 353 controls the amount of light of the LED 400. Specifically, when the manager 100 inputs a control command for adjusting the light amount of the LED 400, the dimming control unit 353 controls the dimming control unit 353 If the amount of light desired by the administrator is lower than the LED 400, the amount of light of the LED 400 is reduced. If the amount of light desired by the administrator is higher than the LED 400 The amount of light of the LED 400 is increased so that the light amount is easily adjusted by the administrator.

The relay control unit 355 controls the first relay circuit 301 and the second relay circuit 303 so that when an administrator operates the LED 400 or a short circuit of the LED 400 occurs, And the LED 400 may be shut off by the first relay circuit 301 or the second relay circuit 303. It is needless to say that the administrator can perform the function of confirming the abnormality of the first relay circuit 301 or the second relay circuit 303.

If the control server 100 has exceeded the electric leakage current amount in the control server 100, the control server 100 transmits a control command for blocking the second relay circuit 303 in the relay control unit 355 to the electric leakage blocking unit 333 (S150). The electric leakage blocking unit 333 receiving the control command from the relay control unit 355 is configured to shut off the second relay circuit 303 (S160).
