Solar energy self-timing light emitting diode matrix lamp

Technical field

The utility model relates to the electric source lighting technical field, specifically is a kind of solar energy self-timing light emitting diode matrix lamp.

Background technology

The solar-electricity source lighting, its energy is inexhaustible, and is pollution-free etc., and plurality of advantages is more and more applied.But the illumination of many occasions only just utilizes solar energy to make energy resource supply, and it is few that solar energy is controlled the timing lighting application automatically, and especially the illumination of occasions such as the orchard, rural area of power supply inconvenience, pasture seldom.

The purpose of the utility model provides a kind of solar energy self-timing light emitting diode matrix lamp of ac power supply inconvenience occasion illumination.

The utility model technical solution is: comprise solar panel, storage battery, blocking diode, light emitting diode matrix lamp; Also comprise electronic transformer, photo resistance, Schmidt trigger, timer, triode current amplifier and relay; Wherein, Battery tension is connected to an end, Schmidt trigger, timer, triode current amplifier, the relay power end of photo resistance, also connects relay normally open and normally closed intermediate contact simultaneously, and the photo resistance other end is connected on the Schmidt trigger input; Schmidt trigger output inserts timer; Timer output is received triode current amplifier and relay through resistance, and relay normally open contact connects electronic transformer to light emitting diode matrix lamp, and normally-closed contact connects solar panel through blocking diode;

Electronic transformer is formed bridge-type oscillator by large power triode, resistance, electric capacity and ferrite transformer, and by high-power FET MOS full-wave rectification, driven for emitting lights diode array lamp.

The utility model produces good effect: daytime solar panel to charge in batteries, night storage battery to light emitting diode matrix lamp powered lighting, regularly turn off the light, light efficiency is high, long service life, the illumination that solves ac power supply inconvenience occasion.

The practical implementation method

With reference to Fig. 1,2; The utility model practical implementation method and embodiment: comprise solar panel 1, storage battery 3, blocking diode 2, light emitting diode matrix lamp 9; Also comprise electronic transformer 8, photo resistance 4, Schmidt trigger 5, timer 6, triode current amplifier and relay 7; Wherein, Storage battery 3 voltages are connected to an end, Schmidt trigger 5, timer 6, triode current amplifier and relay 7 power ends of photo resistance 4, also connect relay normally open and normally closed intermediate contact simultaneously, and photo resistance 4 other ends are connected on Schmidt trigger 5 inputs; Schmidt trigger 5 outputs insert timer 6; Timer 6 outputs are received triode current amplifier and relay 7 through resistance, and relay normally open contact connects electronic transformer 8 to light emitting diode matrix lamp 9, and normally-closed contact connects solar panel 1 through blocking diode 2.

Fig. 2, on daytime, blocking diode VD unilateal conduction makes solar battery group to charge in batteries when solar radiation.At night, blocking diode VD oppositely stops storage battery E voltage to be transmitted electricity to solar panel A during no solar radiation.

Because photo resistance R1 is low-resistance under the daylight effect, Schmidt trigger IC1 is output as low level, and timer IC2, triode current amplifier VT and relay J are not worked; And the relay J normally-closed contact is connected solar panel A and storage battery E through blocking diode VD; Irradiate light solar panel A becomes electric energy to storage battery E charging, at this moment transform light energy; The relay J normally opened contact does not have energising to electronic transformer B, and LED array lamp does not work.Night is unglazed to be high resistant according to effect photo resistance R1; IC1 is output as high level, makes timer IC2, triode current amplifier VT and relay J work, and normally opened contact is connected the electronic transformer B-source; LED array lamp is lighted; Arrive timer IC2 timing, the relay J normally opened contact discharges and cuts off the electronic transformer B-source, and LED array lamp extinguishes.

The resistance R 3 that timer IC2 is set discharges and recharges the time with capacitor C 1, can select the light emitting diode matrix lamp operating time easily.Schmidt trigger IC1 and timer IC2 adopt dual time base circuit 556, also available two single time-base circuits 555.Resistance R 2 is supplied with the photo resistance bias voltage.
