Abstract
A charge and discharge control circuit of a solar lamp constitutes of a solar charge and discharge circuit composed of a solar battery set T, an accumulator battery E, and a charging diode D3, and a lamp UL, wherein the solar charge and discharge circuit and the lamp UL are switched by a switch tube Q1, a diode D2 and a resistor R1 are connected in series and then connected with the lamp UL in parallel. By means of sunniness by daylight, the solar battery T generates power, a higher electric potential is generated at a point A, a diode D3 is switched on, the accumulator battery E is charged, the electric potential of a base electrode of the switch tube Q1 is higher than that of an emitter of the switch tube, and a lamp UL circuit is switched off by the switch tube Q1; namely the accumulator battery E is automatically charged by the solar battery T at daytime, and the lamp UL is automatically switched off. At night or light is dark, the electric potential of the point A is low, the diode D3 is switched off, the accumulator battery E stops to charge, the electric potential of the base electrode of the switch tube Q1 is lower than that of the emitter, the resistor R1 is adjusted to make the switch tube Q1 to satisfy required conditions to be saturatedly conductive, and the accumulator battery E provides a current for the lamp UL.

Embodiment
The charge-discharge control circuit that a kind of Solar lamp is used, by charge power supply solar battery group T, batteries E, the sharp light fixture U of the solar charging/discharging circuit that charging diode D3 forms
LBe composed in series, it is characterized in that, lamp U
LAnd the solar charging/discharging circuit and between switch control be power switch pipe Q1, lamp U
LWith stabistor D2, resistance R 1 parallel connection, wherein stabistor D2 and resistance R 1 series connection.When charging work when solar radiation (by day), solar battery group T generating is at the higher current potential of A point generation, diode D
3Open accumulators group E charging, Q
1Base potential is higher than the emitting stage current potential, switching tube Q
1Turn-off U
LCircuit; Be to charge lamp U automatically by solar battery group T accumulators group E daytime
LThe moving shutoff.And when night or light were dark, then A point current potential was lower, D
3Turn-off, batteries E stops charging, Q
1Base potential is lower than the emitter current potential, regulates resistance R
1, can make Q
1Satisfy required condition saturation conduction, then storage battery E provides electric current by the A point, and the B point makes lamp U
LWork.Change electric attached R1, just can change concrete outside illumination starting to control a little this contactor corridor lamp.It is power supply that this utility model can be widely used in the solar battery group of making the energy with sunlight, and common low voltage bulb is in the solar energy lamp and solar energy toy car and boat, model plane and communication equipment etc. of light emitting source.
In order to prevent overcharging of batteries E; utilize the reverse-conducting characteristic of voltage stabilizing didoe; voltage stabilizing didoe D1 and batteries E form a loop; voltage stabilizing didoe D1 plays the effect of over-charge protective to batteries E; battery has been full of, and unnecessary meeting bypasses and works as solar battery group T from D1 and stops charging accumulator group E to lamp U
LDuring power supply, voltage stabilizing didoe D2 plays the over effect because the reverse-conducting characteristic is arranged to batteries E.
Solar battery group T also is in series with diode D4, utilizes the unidirectional on state characteristic of diode D4, and charge power supply solar battery group T plays and prevents anti-protection of filling.
Lamp U
LD5 is in parallel with diode, because diode D5 has unidirectional on state characteristic, to lamp U
LPlay the reverse protection effect, also play electrostatic protection and lightning strike protection simultaneously.
Used lamp U
LBe LED Lamp cup or low-pressure energy-saving bulb or corridor lamp, show window lamp, Lawn lamp, garden lamp, street lamp and indicator light etc.
Lamp U
LCan be connected in series an audio-switch in the line, perhaps soft-touch control, perhaps pulling switch can be realized the method for the various control lamp in evening.Also can be lamp U
LAccess point to the C point, can be realized 24 hours various control methods by B point reconfiguration like this.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection range of the present utility model should be defined with the application's claim protection range is as the criterion.
