Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
nullRefer to Fig. 1，In this utility model embodiment，A kind of photovoltaic LED enabling delayed lamp circuit，Including diode D1、Solar panels T、Chip IC 1 and switch S1，The anode of described diode D1 connects solar panels T，The negative electrode of diode D1 connects resistance R1、Inductance L1、The contact K-1 of relay K and relay K，The other end of the contact K-1 of relay K connects the positive pole of accumulator E，The other end of resistance R1 connects negative electrode and the negative electrode of diode D2 of diode D3，The anode of diode D2 connects the negative pole of accumulator E、The other end of solar panels T、The emitter stage of audion V1、Resistance R3、Electric capacity C1、Electric capacity C2、The pin 1 of chip IC 1 and LED lamp H，The base stage of the anode connecting triode V1 of diode D3，The other end of the collector connection relay K of audion V1，The other end of inductance L1 connects anode and the pin 2 of chip IC 1 of diode D4，The negative electrode of diode D4 connects the other end of electric capacity C1、Switch S1、The colelctor electrode of audion V2 and the pin 3 of chip IC 1，The other end of switch S1 connects the other end of resistance R3、The other end of electric capacity C2 and resistance R2，The base stage of the other end connecting triode V2 of resistance R2，The emitter stage of audion V2 connects the other end of LED lamp H，The model of described chip IC 1 is SL8203.
Switch S1 is reed switch.Resistance R3 is photoconductive resistance.
nullOperation principle of the present utility model is: solar panels T completes opto-electronic conversion and by electric energy by resistance R1、Diode D3 is added in the base stage of audion V1，Audion V1 is turned on，Relay K is energized，The K-1 adhesive of its contact，Solar panels T charges to accumulator E through the contact K-1 of relay K，Owing to this circuit is in order to reduce volume，Use 3V small size solar panels，Therefore the inductance L1 in circuit、Electric capacity C3、Diode D2 and chip IC 1 constitute DC-DC booster circuit，The low-voltage of the low-voltage output for solar panels or accumulator being exported is increased to be enough to drive the DC voltage of loaded work piece，Resistance R1、Diode D2 and diode D3 forms undervoltage detection circuit，When accumulator E discharge for a long time cause its voltage to be reduced to marginal value time，Its undertension is to maintain the conducting of diode D3，Audion V1 ends，Relay K disconnects，Storage battery under-voltage is avoided to power，Switch S1 is，Gate controlled switch，During enabling，S1 turns on，If being now daytime，The resistance of photoconductive resistance R3 is the lowest，Therefore audion V2 base stage must not electricity，LED lamp H is not lighted，If insufficient light，Resistance R3 resistance raises，Voltage is added in the base stage of audion V2 by switch S1 and resistance R2，LED lamp H is obtained electric，Electric capacity C2 is charged simultaneously，Therefore close electric capacity C3 behind the door and be able to maintain that conducting voltage a period of time of audion V3，Realize the effect of time delayed turn-off.
