Capacitor C2, which charges the output voltage from 540 and the other end is connected to ground (GND), preferably has a capacitance of 4.7 uF and resistor R3 is a resistor. It can be set larger than the size of (R4).

For example, referring to FIG. 4 or FIG. 5, the battery charger 540 measures the voltage of the battery 200 through the third pin 3, and the minimum value of the measured voltage V_BAT of the battery 200 is preset. If the threshold voltage is less than 5.0 V, the battery 200 is charged until the minimum threshold voltage is reached, and while the battery 200 is being charged, the signal output from the first pin 1 is changed. The charging LED LED3 indicating that the battery 200 is in a charging state is turned on.

It may further include a resistor (R5) connected between the input terminal of the first diode (D1).

In this case, if forward current flows to the control unit 500, the first diode D1 is turned on so that the output voltage of the regulator unit 530 is supplied to the driving power supply of the LED lighting unit 300. The second diode D2 is turned on so that the voltage charged in the battery 200 is supplied to the LED lighting unit 300 as driving power.

After passing through the first diode (D1) in order to supply to the LED lighting unit 300, if an emergency situation such as a power failure in the transmission and distribution line (1) no longer flows in the electromotive force This is because the base forward current does not occur, but the reverse current based on the voltage charged by the battery charger 540 is supplied to the LED lighting unit 300 through the second diode D2.
