Description
Technical field
The present invention relates to a kind of light-operated LED road lamp driver of pulse-width regulated formula.
Background technology
LED illumination lamp obtains application with the high advantage in its electricity-saving rate in street lamp field at present, and the simply application of LED street lamp is worked as
In, street lamp produces very big heat, because heat is transformed by electric energy, a lot of electric energy of too high thermal losses；
The heat being again too high makes LED street lamp produce light decay, so that street lamp is damaged when serious.
Content of the invention
A kind of light-operated LED road lamp driver of present invention pulse-width regulated formula, such as by driver applications in street lamp, can make street lamp
Both electricity-saving rate improved 50% than common LED street lamp, makes the operating temperature of street lamp be maintained at less than 50 DEG C again, makes street lamp realize LED
TAHIZ theorem：" when LED operation temperature is below 25～50 DEG C, service life is 50,000 hours ".
A kind of light-operated LED road lamp driver of present invention pulse-width regulated formula, its circuit forms by rectification circuit, power factor
Improve circuit, filter circuit, light-operated circuit, timer circuit and pulse width modulation circuit composition.
Brief description
Accompanying drawing is a kind of circuit theory diagrams of the light-operated LED road lamp driver of pulse-width regulated formula.
Specific embodiment
As shown in drawings, IC2 and peripheral circuit composition light-operated circuit, R15 is photoconductive resistance.On daytime, light irradiates
R15, its resistance reduces, and causes 2, the 6 foot current potentials of IC2 to raise, when 2,6 foot voltages are more than 2/3 supply voltage, 3 feet of IC2 are defeated
Go out low level, relay J is failure to actuate, the J not adhesive of its normally opened contact, LED does not obtain working power, does not work；When The night screen has hung down,
The resistance of R15 uprises, 2, the 6 foot current potential step-downs of IC2, and when 2,6 foot voltages are less than 1/3 supply voltage, the 3 foot outputs of IC2 are high
Level, relay J action, the J adhesive of its normally opened contact, connect the L loop of alternating current power supply, the operating circuit of LED street lamp obtains power supply
Devote oneself to work.Now, the intervalometer timer counter of IC4 starts, and its 3 foot exports low level, and 5,6 through IC5 anti-phase driving IC6 are obtained
Power supply must be triggered, IC6 is the analogue relay chip of model CD4066,5,6 feet be two groups of analogue relay normally opened dynamic
Make, after 5,6 feet obtain power supplys, the equal adhesive of two groups of normally opened relays, 2,6 feet and resistance R6, R8 of IC3 is connected with parallel way
Connected one end, is made IC3 be exported with big dutycycle, so that LED street lamp is operated in vehement bright operating mode；In the continuous work of LED street lamp
After the time counting of one setting value of work arrives, 3 feet of IC4 become high level output by low level again, and 5,6 ends making IC6 are by height
Level is changed into low level, the loop that tripping IC6 and R6, R8 are connect；Meanwhile, the high point of IC4 puts down 12,13 feet driving IC6,
Make the equal adhesive of two groups of normally opened relays, one end that 2,6 feet connecting IC3 with parallel way are connected with resistance R7, R8, make IC3 with
Little dutycycle output, makes LED street lamp be operated in secretly bright operating mode, realizes timing automatic dimming function.
As shown in drawings, IC1 is rectification circuit, and its composition is single-phase bridge rectification heap, and alternating current 220V is become pulsation
Direct current electricity output, after being then passed through filter circuit L, C3 filtering, the smoother unidirectional current obtaining about 300V supplies LED to work
Power supply.
As shown in drawings, C1, C2 and D1, D3 group power factor improve circuit.Because the direct current of rectifier output
Electricity is the unidirectional current of pulsation, and the waveform of its curtage is discontinuous, causes the power factor of load low, have impact on work
The utilization rate of power supply.In order to improve the utilization rate of power supply, in order to improve power factor, introduce power factor and improve circuit, its work(
It can be the power factor improving street lamp.
As shown in drawings, IC3 and peripheral circuit composition pulse width modulation controlled output circuit, control point by intervalometer IC4,
IC5, IC6 control.Control process is：IC3 is the time-base counter chain chip of model 555, forms arteries and veins by itself and peripheral circuit
Wide adjustable circuit, is the pulse-width regulated function using IC3, controls different dutycycle outputs, when that is, street lamp is just started working,
With vehement bright operating mode work；After the continuous setting time that works of vehement bright operating mode count down to, by IC4, IC5, IC6, street lamp is vehement
Bright operating mode is changed into secretly bright operating mode, thus realizing timing automatic dimming function.
As shown in drawings, IC4 and peripheral circuit composition timer circuit, IC4 is the IC chip of model CD4060, IC4
12 feet be electrifying self-resetting end, just obtained the moment of power supply in IC4,12 feet input positive pulse signals, made the inside electricity of IC4
Road resets, and the low level of the 3 foot output lockings of IC4.Electric capacity C13, the resistance R12 composition that 9 feet of IC4,10 feet are connected
The timing constant of intervalometer, selects suitable numerical value, you can meet required timing.The external D9 of 11 feet of IC4,
Its function is when inputting a high level, the internal circuit blocking of oscillator of effect IC4, and maintains the statusquo, until work
Point source is switched off.
As shown in drawings, V is varistor, plays the over-voltage protecting function of moment in circuit；C4, R1 and C8, R4 are
Two groups of capacitance-resistance voltage reduction circuits, reduce alternating current 220V and send rectification circuit after some volts；B1, B2 are two single-phase bridge rectification heaps,
The unidirectional current that alternating current is become pulsation sends to filter circuit；C5 and C9 is two filter circuits, and its function is pulsation
Unidirectional current becomes smoother unidirectional current；D4 and D6 is both-end stabilivolt, plays and be stable at certain threshold voltage in respective circuit
Function；R3 closes C6 composition light interference absorbing circuit, prevents the light such as light or the lightning flashes of night car from so that street lamp is extinguished.
