Diode D3 is light emitting diode.
Operation principle of the present utility model is: diode D2, relay J, audion V2, resistance R4 and diode D3 in circuit form under-voltage protection indicating circuit; the base stage of the audion V2 under normal circumstances of the voltage in accumulator E obtains electric; audion V2 is not turned on; relay J and light emitting diode D3 do not light; therefore the normally-closed contact of relay J-1 is failure to actuate; subsequent conditioning circuit obtains electric work, resistance R1 set Determination of Critical Transition Point.According to Ohm's law, if the value of resistance R1 is 10 Ω, if flow through electric current thereon less than 70mA, voltage the most thereon be less than 0.7V, i.e. less than audion V1 e-b tie conducting voltage, V1 cut-off and inoperative.Then voltage adjuster IC1 is operated in intrinsic linear condition.When electric current is more than 70mA, this circuit is automatically converted on off state.Voltage on R1 is more than 0.7V, makes switch voltage-stabilizing pipe V1 turn on, has electric current to flow through coil L2 so that it is magnetic core is magnetized.Resistance R2 and R3 constitutes a bleeder circuit, provides positive feedback for IC1.When the voltage being added in A two ends rises above 5V, the electric current flowing through IC1 reduces.Therefore V1 turns off.Inductance L2 discharges its magnetic energy stored through D1, C3, and produced induction electromotive force adds to load A.Continuous repetitive cycling of this working cycle, thus realize the purpose of voltage stabilizing output, electric capacity C1, electric capacity C2 and inductance L1 in circuit form pi type filter, it is possible to the interference caused due to light intensity change when eliminating solar panels opto-electronic conversion, increase the stability of circuit.When running into undertension in accumulator E, its undertension is with breakdown diode D2, and therefore audion V2 conducting, relay J turns on, and its contact J-1 disconnects subsequent conditioning circuit, and light emitting diode D3 lights as lamplight pointing simultaneously.
