The specific embodiment
Consult Fig. 2, the utility model be described in further detail:
Light-operated circuit IC1 switching mode visible light illuminance transducer 3 pin level are higher during daytime, 2 pin are that high level electronic switch Q4, Q3 do not work by other circuit, have only light-operated circuit and over-discharge protection circuit operating switch type visible light illuminance transducer quiescent current to have only several microamperes, so the utilization rate of electrical that the little microampere order battery output of quiescent dissipation is used to throw light on is higher; Adjust the R3 resistance and can adjust IC1 unlatching illumination, both changed its 3 pin cut-in voltage, when light during from bright attitude to dark attitude or from dark attitude to bright attitude transition, there is an illumination return difference about 10% inside, 2 pin hold modes were constant when both 3 pin voltages changed within the specific limits, can not cause frequent on-off phenomenon; While solar cell U1; D1 charges to battery U2 through back discharge protection diode; the D2 conducting makes Q1 conducting short circuit solar cell when battery tension reaches charging limit voltage, solar cell U1 both end voltage is reduced stop battery U2 charge protection battery is not overcharged.
When at dark, light-operated circuit IC13 pin level is lower, 2 pin are low level electronic switch Q4, the Q3 conducting, for the LED constant-current drive circuit provides power supply, at this moment LED current control circuit Q5 ends very high level LED constant-current drive circuit IC4 (LED constant current driving special IC of current collection, having DC dimming function LED electric light when the R21 terminal voltage increases reduces, otherwise the LED electric light increases) be that little electric current constant current drives, great power LED is sent out the low light level, simultaneously voltage-stabilized power supply IC2 provides power supply for infrared induction and treatment circuit, detecting human infrared signal 2 pin after infrared sensor treatment circuit IC3 handles as man-hour infrared sensor PIR is high level and delays time a period of time, at this moment LED current control circuit Q5 conducting current collection very low level LED constant-current drive circuit IC4 is that big electric current constant current drives, great power LED is sent out high light and sent out the low light level after a period of time of delaying time has man-hour can send out high light continuously continuously, make LED avoid heavy current impact and prolong its service life, delay time is by R17, C7 decision C1 is a filter capacitor; Further step-down after over-discharge protection circuit Q2 base voltage passes through R7, R8 dividing potential drop when battery U2 voltage is low, collector voltage uprises and adds to light-operated circuit IC1 3 pin by isolating diode D3 to make higher 2 pin of its 3 pin level be that high level electronic switch Q4, Q3 end, battery stops discharge, and the protection battery is crossed and put; Utilize the inner illumination return difference of light-operated circuit IC1 also can make the battery back voltage that stops to discharge go up or be with after the load voltage to descend and cause the frequent switch of electronic switch and LED is glimmered; So the utility model: working stability, brightness stability, quiescent dissipation is little, simple in structure, cost is low, easy to use, the life-span is long, utilization rate of electrical is high, the long-time low light level of sending out when night, nobody walked about is sent out high light or can be sent out high light continuously when the someone walks about continuously when the someone walks about; Make LED avoid heavy current impact and prolong its service life; The illumination and the decoration in places such as suitable especially outdoor lawn, greenery patches, sub-district, school or gardens use.
