When the current of the proper voltage is input to the EN terminal, it is operated (ON). If a current larger or smaller than the proper voltage is input, (OFF).

The switching diode D2 of the charging unit 1 is connected in series to the power supply line and is turned ON when the forward voltage is applied and turned OFF when the reverse voltage is applied, that is, from the JACK + IN1 to the decreasing regulator IC1 When the current flows, it is turned on. When current flows from the decrement controller IC1 to the direction of JACK + IN1, the current is turned off and the switching is performed at high speed according to the input current.

The instantaneous voltage suppressing diode D3 of the charging unit 1 is connected in parallel to the power line and the ground between the switching diode D2 and the capacitor C1 and a surge voltage that damages the circuit from the power source, that is, the switching diode D2, , It is bypassed to ground and a constant voltage current is applied to the reduction regulator IC1 to protect the circuits after the instantaneous voltage suppression diode D3 from the surge voltage.

The instantaneous voltage suppressing diode D3 is turned on when a voltage equal to or higher than a certain voltage is generated due to a current input to the charger 1 being charged and discharged in the capacitors C1, C2, and C3 or a malfunction of the decrease controller IC1, That is, the ground line, and stops the flow of the current when the voltage is lower than a specific voltage to maintain a constant voltage, and then flows to the decrement controller IC1 And the current becomes a constant voltage.

The current applied to the charging unit 1 is sequentially charged in the order of the capacitor C1 → the capacitor C2 → the capacitor C3 and the current charged in the capacitors C1, The current does not flow.

When the DC current charged in the capacitors C1, C2, and C3 reaches a predetermined value or more, the resistor R1 connects the positive and negative terminals of the capacitors C1, C2, and C3 while connecting the capacitors C1, C2, And the current charged in the capacitors C1, C2 and C3 is discharged to be inputted to the decrement controller IC1.

The resistor R14 of the charging unit 1 causes the 24V current applied from the decrement controller IC1 to be turned ON to charge the capacitor C7 while the capacitor C7 discharges the charged power supply to the reduction regulator IC1 ) And the 24V current output from the inductor (L1) is reduced to 12V by feeding back the power to the MOSFET switch built in the regulator (IC1), so that the input power is used for 12V and 24V .

The inductor L1 removes electromagnetic interference (EMI) generated by the decrease controller IC1. The inductor L1 can not transmit a signal because the resistance of the inductor L1 increases as the frequency increases, that is, as the frequency increases. R5 passes the current output from the inductor L1 until the output current of the inductor L1 becomes a stable low frequency to continue feedback to the decrement controller IC1 and the resistor R4 does not pass through the resistor R5 Bypassing the overvoltage current in a faulty current causes it to be applied to ground.

Meanwhile, the reduction controller IC1 of the charging unit 1 is connected to the ground line while the capacitor R2 is connected in series with the capacitor C5 and the resistor R2 in series.

When the first switch SW1 is turned on by the operation of the switches SW1 and SW2, that is, when the power source of the charge control unit 2 is in the charging state in the power storage unit 3 or the power storage unit 3, The resistors R12 and R15 cause the constant current to be supplied to the LED module 5 or the first and second blinking devices 4-1 and 4-2 and the capacitors C9 and C11 And the transistors TR1 and TR2 perform a switching operation by discharging the capacitors C9 and C11.

When the power is applied to the blinking part 4, the operation characteristics of the transistor TR1 and the transistor TR2, the difference in sensitivity, the resistance of the resistor R12 and the resistance R15 The transistor TR1 and the transistor TR2 first conduct electricity and operate because of a small difference such as a value error.

When one of the transistors TR1 and TR2 is turned ON because the characteristics of the transistors TR1 and TR2 are not identical to each other, the other is turned off.

 When the voltage is first applied to the blinking part 4, the capacitors C9 and C11 are charged while the current is flowing for a short period of time. Assuming that the capacitor C11 has completed charging before the capacitor C9, A slight current flows and the current flows to the base of the transistor TR1 so that the transistor TR1 operates and the collector of the transistor TR1 and the emitter of the transistor TR1 are turned on The voltage charged in the capacitor C11 is discharged by the instantly charged voltage.

At this moment, no current flows through the capacitor C9 after the capacitor C9 is charged, no current flows to the base of the transistor TR1, so that the voltage is not generated, and the capacitor C11 starts charging again, The transistor TR2 is activated by the current so that the capacitor C9 discharges the charged voltage through the collector TR1 and the emitter of the transistor TR2.

The phases of the two spherical pulse springs are opposite to each other and the balance is broken due to the difference in charging time of the capacitor C11 and the capacitor C9, The voltage of the capacitors C11 and C9 is discharged.

When the base voltage Vb2 of the transistor TR2 rises slightly from zero voltage, the transistor TR1 is turned on and the voltage of the capacitor C11 becomes almost zero The charge of the capacitor C11 is discharged through the resistor R15 and the charge of the capacitor C11 is discharged through the resistor R15. The red LED 41-1 is turned on for the time.

The transistor TR1 is turned on and the transistor TR2 is turned off when the charging of the capacitor C11 is completed and the capacitor C9 is completely charged, that is, when the capacitor C9 is discharged. The voltage between the collector and the emitter of the transistor TR1, that is, the collector voltage Vc1 of the transistor TR1 becomes substantially zero when the transistor TR1 is connected, The transistor TR2 is cut off and is almost in a state of a power supply voltage.

When the transistor TR1 is ON, the charge slightly charged in the capacitor C11 is discharged by the transistor TR2 and the resistor R15, and the base of the transistor TR2 gradually becomes zero voltage The capacitor C9 is charged therebetween and the voltage between the base and the ground of the transistor TR1, that is, the base voltage Vb1 of the transistor TR1 is close to zero voltage Loses.

When the base voltage Vb1 of the transistor TR1 slightly increases from zero voltage, the transistor TR2 is turned on and the voltage of the capacitor C9 is almost zero The charge of the capacitor C9 is discharged through the resistor R12 and the voltage of the blue color of the three-color LEDs LED4, LED5, LED6, LED7, LED8, LED9, LED10, LED11, LED12, LED13, LED14, LED15, LED16, LED17, And the green LEDs 41-2 and 41-3 are turned on at the same time.
