Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model rather than whole embodiments.Based on the embodiment in the 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 the utility model protection.

Refer to Fig. 1～2, in the utility model embodiment, a kind of solar LED control system, including AC/DC change-over circuit, low-voltage control switch, battery, light-controlled switching circuit, accumulator super-charge protection circuit and solar panel array, described AC/DC change-over circuit connects 220V electric main and low-voltage control switch respectively, low-voltage control switch is also respectively connected with battery and light-controlled switching circuit, described solar panel array is sequentially connected with accumulator super-charge protection circuit, battery, light-controlled switching circuit, infrared controlled switch circuit and LED lamp, LED lamp connects infrared controlled switch circuit also by delay circuit.

Described accumulator super-charge protection circuit includes resistance R1, resistance R2, triode VT1, diode D1 and diode D2; triode VT1 emitter stage connects resistance R1, solar panel array and battery respectively; the battery other end connects resistance R2; the resistance R2 other end connecting triode VT1 colelctor electrode and diode D2 negative pole respectively; diode D2 cathode connecting diode D1 positive pole; diode D1 negative pole connecting triode VT1 base stage and the resistance R1 other end respectively, described diode is all Zener diode.

Operation principle of the present utility model is: refer to Fig. 1, and power supply of the present utility model is divided into battery and 220V electric main two parts, and 220V electric main obtains stabilized power source after AC/DC change-over circuit.

This system has 2 energy-conservation parts: first, uses solar panel array to generate electricity as the energy, it is achieved zero loss of LED lamp illumination；Second, subsequent conditioning circuit uses light-controlled switching circuit and infrared controlled switch circuit, it is achieved people is bright to lamp, the effect turned off the light when you leave, simultaneously under continuous rainy weather, use back-up source 220 V to power, it is ensured that normal circuit operation.

On daytime, light-controlled switching circuit is in open mode, and subsequent control circuit does not works, and LED lamp does not works；Evening, light-controlled switching circuit closes automatically, when pedestrian passes by, arrived by infrared controlled switch electric circuit inspection, infrared controlled switch closes, and LED lamp lights, and delay circuit starts simultaneously, street lamp automatic distinguishing after tens of seconds, when running into continuous rainy weather, battery tension is too low, reaches low-voltage control switch when opening threshold value, switch Guan Bi automatically, circuit is switched to 220V electric main and powers, and through AC/DC change-over circuit, galvanic current source is delivered to light-controlled switching circuit, to realize replacing battery-driven purpose, also achieve energy-conservation effect simultaneously.

Refer to Fig. 2, D1 and D2 collectively constitutes the biasing circuit of triode VT1, R1 is the current-limiting resistance of VT1 pipe, during circuit charging, by the high threshold voltage of battery as a example by 14V, slowly rise in charging initial stage battery under-voltage condition routinely, when battery tension reaches the breakdown voltage of voltage-stabiliser tube D2, D1 pipe begins to turn on, now VT1 pipe is also switched on, the branch road both end voltage promoting R2 and battery composition declines, arranging suitable parameter makes battery both end voltage peak be not more than 14 V, when battery has been filled with, protection circuit can make battery be in trickle charge state, this just makes battery have charging protection function.
