Description of drawings

Accompanying drawing 1 is a structured flowchart of the present utility model.

Accompanying drawing 2 is circuit structure diagrams of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, solar street light is made up of solar cell, control circuit, battery and white LED lamp; Solar cell is connected with control circuit, and control circuit is connected with battery, and white LED lamp is connected with control circuit.

As shown in Figure 2, E1 is a solar cell, E2 is the Ni-Mh nickel-hydrogen accumulator, is two joint series connection, and voltage reaches 2.4V, capacity is 1500mAh, R1 is the power that photo resistance is used for detecting light, and daytime, the electric energy that solar cell E1 produces was battery E2 charging by isolating diode D1 when sunshine, resistance R 1 is low resistance, and triode BG2 base stage is that low level is ended; When evening was unglazed, solar cell stopped to be charge in batteries, and being provided with of diode D1 stoped battery to the solar cell back discharge; The R1 of photo resistance simultaneously becomes high value by low resistance, triode BG2 conducting, triode BG1 base stage is also conducting of low level, by triode BG3, BG4, capacitor C2, resistance R 5, R6, the DC voltage booster circuit that R7 and inductance L are formed gets electric work, white led lamps gets electroluminescence, its principle of luminosity is: when triode BG1 conducting, power supply passes through inductance L, resistance R 5, triode BG2 charges to C2, because capacitor C 2 both end voltage can not be suddenlyd change, triode BG3 base stage becomes high level, and not conducting of triode BG3 is along with the charging voltage of C2 is more and more higher, the BG3 base potential is more and more lower, BG3 conducting when being low to moderate triode BG3 conducting voltage, triode BG4 base potential raises, triode BG4 conducting, capacitor C 2 is by triode BG4 discharge, behind the discharge off, triode BG3, BG4 ends once more, and power supply charges to C2 once more, so go round and begin again, circuit forms vibration; In oscillatory process, during triode BG4 conducting, electric current is flowed through the ec utmost point, inductance L, the triode ce utmost point of triode BG1 to ground, and electric current is through the L energy reserve; When triode BG4 ended, the L two ends produce induced electromotive force and supply voltage stack rear drive LED is luminous, and promptly evening, solar street light was lighted automatically.For preventing battery overdischarge, increase resistance R 4 in the circuit and triode BG2 constitutes the over circuit, when cell voltage was low to moderate 2V, because the dividing potential drop of resistance R 4 makes the triode BG2 can not conducting, circuit quit work, and battery is protected.

Component parameter: R1-R7 selects the carbon film resistor of 1/8W for use; E2 selects the Ni-Mh nickel-hydrogen accumulator for use; Diode D1 selects IN5812 for use; Triode BG1, BG3 select positive-negative-positive C9015 for use, and triode BG2 selects NPN type C9014 for use, and triode BG4 selects positive-negative-positive C9013 for use; LED1, LED2, LED3 select the high brightness white light-emitting diode for use; It is 100uH that inductance L is selected inductance value for use; C1, C2 select the monolithic capacitor of 300P for use, and C3 selects that capacity 10u is withstand voltage to be the aluminium electrolutic capacitor of 16V for use.

The utility model also can be made various flexible mode, more than by the specific embodiment by accompanying drawing 1 and accompanying drawing 2 illustrated embodiments, be that foregoing of the present utility model is described in further detail, but this should be interpreted as that the scope of the theme that the utility model is above-mentioned only limits to described example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements and change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
