Abstract
A multifunctional light-operated LED streetlamp driver has a function of utilizing a photovoltaic effect of a solar cell, can enable a streetlamp to automatically switch off in the daytime and switch on at night. The multifunctional light-operated LED streetlamp driver utilizes a PWM dimming function, and adopts a control circuit to change a duty ratio in a timed manner, so as to change average LED streetlamp operating current output by PWM, and achieve an automatic dimming function. When the multifunctional light-operated LED streetlamp driver is applied to the streetlamp, operation of a refrigeration slice and operation of the LED streetlamp are synchronized by utilizing sealing cavity and semiconductor refrigeration slice technologies, so that heat generated by the LED streetlamp in operation is neutralized and radiated by the semiconductor refrigeration slice, the operating temperature of the streetlamp can be controlled below 50 DEG C, and the HATIZ theorem of an LED can be realized, namely, the service life of the LED is 100000 hours when the operating temperature of the LED is below 25 DEG C; and the service life of the LED is 50000 hours when the operating temperature of the LED ranges from 25 to 50 DEG C.

Technical field
The present invention relates to a kind of multi-functional light-operated LED road lamp driver.
Technical background
Current LED street lamp eliminates the large incandescent lamp & lantern street lamp of power consumption progressively to make pottery from the advantage of the energy-conservation environmental protection again of height, be just normal on the function singleness of LED street lamp, can only vehement bright work, can not be with an automatic light meter, more there is no electronic radiation function, the energy-saving efficiency of street lamp is not given full play to; The durability of street lamp is made not reach the due time limit.
Summary of the invention
A kind of multi-functional light-operated LED road lamp driver, has the function of the photovoltaic effect utilizing solar cell, street lamp is turned off the light automatically by day automatically; Automatically turn on light again at night; Utilize PWM dimming function, adopt control circuit timing to change duty ratio, thus change the operating current of the average LED street lamp that PWM exports, reach automatic dimming function; At the street lamp of driver drives, utilize annular seal space and semiconductor refrigerating chip technology, cooling piece is synchronous with the work of LED street lamp, the heat produced when LED street lamp is worked carries out neutralization by semiconductor chilling plate and dispels the heat, the working temperature of street lamp is controlled below 50 DEG C, realize the HATIZ theorem of LED: " when LED working temperature is below 25 DEG C, useful life is 100,000 hours; When 25 ~ 50 DEG C, useful life is 50,000 hours.”
A kind of multi-functional light-operated LED road lamp driver, its circuit composition is made up of photovoltaic effect circuit, thyristor control circuit, pulse transformer circuit, duty cycle circuit, timer circuit, electronic radiation circuit.
Accompanying drawing explanation
Accompanying drawing is a kind of circuit theory diagrams of multi-functional light-operated LED road lamp driver.
Embodiment
As shown in drawings, C1, R1 form capacitance-resistance voltage reduction circuit, fall alternating current 220V voltage and reduce some volts and send next stage circuit; R2, R3, D2, D3, C2 form half-wave rectifying circuit and filter circuit, after voltage-stabiliser tube D4 voltage stabilizing, export more stable voltage merit to next stage circuit; E, R4, R5, T4 form photovoltaic effect circuit, and E is solar cell, and solar cell has photovoltaic effect, under the effect of light, namely produce voltage.This voltage driven triode T4 works, and the collector electrode C of triode connects the control end of bidirectional thyristor D1.By day, have illumination to penetrate solar cell E, battery E just produces voltage, when the magnitude of voltage that E produces reaches certain value, triode T4 conducting, C electrode potential drags down the voltage that R3 holds in less than 1 volt, make bidirectional thyristor D1 not obtain trigger voltage, bidirectional thyristor T4 ends, and LED street lamp does not work; At night, unglazed irradiation solar cell E, triode T4 end, and the electricity of R3 end directly sets out bidirectional thyristor D1, D1 conducting, alternating current is delivered to next stage circuit, under the effect of circuits, makes street lamp bright.
As shown in drawings, G is pulse transformer, and B1 is single-phase rectifier, and L, C3 form compound filter circuit, and VT is field effect transistor, for exporting pwm pulse control signal.The course of work of this part circuit: when after bidirectional thyristor D1 conducting, alternating current 220V power supply is through over commutation, filtering, and the smooth direct current electricity supply pulse transformer exporting about 300V is working power.
R7, C7 form capacitance-resistance voltage reduction circuit, and fall after alternating voltage that bidirectional thyristor D1 exports reduces some volts, give rectification circuit B2, C is filter circuit, and the Rectified alternating current that B2 exports is become smoother direct current and send three terminal regulator IC3.C9, C10 are filter capacitors, adopt small one and large one electric capacity, and device effect improves galvanic quality.
As shown in drawings, IC4 and peripheral circuit composition PWM light adjusting circuit, its function is the square wave that this circuit output frequency is fixed, duty ratio is adjustable.IC4 to be model be 555 time base chip, have external often to open, normally closed relay contact J, control different duty ratios and export.The contact J being connected on R8 lower end is normally-closed contact; And the contact being connected on R10 upper end is normally opened contact J.The course of work of PWM light adjusting circuit: when the curtain of night arrives, make bidirectional thyristor D1 to after logical by light-operated circuit, IC4, IC5 obtain electricity work, now, and relay J action, electric shock J adhesive often left by device, connect R10 upper end branch road, end opens R8 lower end branch road, and PWM light adjusting circuit exports larger duty ratio, make pulse transformer export large power, allow LED street lamp be operated in vehement bright operating mode; Then, in the vehement bright work setting-up time section of street lamp, and after timer counter arrives, the automatic tripping of relay J, its normally opened contact J tripping, has cut off the branch road that R10 upper end is connected with 7 pin of IC4; Normally-closed contact J closes simultaneously, connects R8 lower end branch road.Now, PWM light adjusting circuit exports smaller duty ratio, makes pulse transformer export little power, allows LED street lamp be operated in secretly bright operating mode, thus realizes automatic dimming function.
As shown in drawings, IC5 and peripheral circuit composition timer circuit, the model of IC5 is external R12, the C12 of 12 pin of CD4060, IC5 is electrifying self-resetting circuit, timing constant resistance during 10 pin of IC5 external resistance R13.When IC5 obtains electricity, self-resetting circuit inputs a positive pulse from 12 pin and resets to internal circuit, now the timer counter of IC5 starts, its 3 end exports the low level voltage of locking, PNP type triode during triode T3, when the 3 pin output low level of IC5, T3 obtains driving voltage and conducting, its normally opened contact J and normally-closed contact J action simultaneously.The diode D10 that 3 pin of IC5 are external, when 3 pin export high level, its high level signal makes the blocking of oscillator connect in 11 pin, and keeps present situation until turn off the light.
As shown in drawings, D6, C4 form halfwave rectifier and filter circuit, with the working power of smoother direct current supply LED.IC1 and peripheral circuit composition electronic radiation circuit, IC1 is semiconductor chilling plate, selects voltage to be 12V, and power is determined by the work rate of street lamp.D11, D12, T1, R6, C5 form high voltage three-terminal voltage-stabilizing circuit, 1 voltage more than 40V is reduced some volts and gives three terminal regulator again, three terminal regulator during IC1, model is 7812, and then the burning voltage of output sends to semi-simple body cooling piece IC2 through C6 filtering is working power.
As shown in drawings, V is piezo-resistance, in circuit the overvoltage protection of its moment.D13 is the fly-wheel diode of relay, plays protection relay.
