Abstract
Disclosed is driver of a novel high-energy-saving automatic light adjustment LED street lamp. According to driver of the novel high-energy-saving automatic light adjustment LED street lamp, the circuit is composed of a resistance-capacitance step-down circuit, a rectifier circuit, a thyristor controlled circuit and a timer circuit. The working process of the street lamp comprises that after the driver is connected with a luminous panel or the street lamp, the LED lamp just starts working in a blazing state, after working continuously for a timed time period, the street lamp automatically halves the power. The driver of the novel high-energy-saving automatic light adjustment LED street lamp has the advantages that the LED street lamp can save 50% more electric energy on the basis of energy saving and avoid damage of ultrahigh voltage of wires at late night, thereby ensuring durability.
Description
Technical field
The present invention relates to the driver of a kind of Novel high-energy-saving LED street lamp with an automatic light meter.
Background technology
For traffic route or the LED street lamp of stairs port passage at home, be all to lack automatic dimming function at present, street lamp vehement bright working always after work, one comes in the second half of the night people or car when all rare, allow street lamp in the same old way vehement bright be obviously waste on an energy; Two carry out after midnight the line voltage distribution overrate sometimes that raises, and can work the mischief to street lamp.
Summary of the invention
The driver of a kind of Novel high-energy-saving of the present invention LED street lamp with an automatic light meter, provide a kind of timing automatic to regulate LED street lamp power functions, LED street lamp is carried out to timing automatic and turn down power, allow LED street lamp be a half by regulating the power of back light to subtract, the advance of its technology is: brightness adjustment control is the electric capacity of the normally opened contact control of a unidirectional thyristor and relay.Utilize the conduction angle aperture control of thyristor, and reduce the half capacitance in capacitance-resistance voltage reduction circuit, realize light modulation and make the power of LED street lamp reduce more than 50% later; The 2nd, by turning down after LED street lamp power, the operating voltage of the LED street lamp 2V left and right that declined before than light modulation, allows LED street lamp escape the harm of circuit extra-high pressure to street lamp after midnight, is conducive to the durable for a long time of LED street lamp.
Timing automatic reduces a LED street lamp for a half-power, and its circuit structure is made up of volt circuit, rectifier circuit, thyristor control circuit, relaxation oscillations circuit and timer circuit capacitance-resistance.
Accompanying drawing explanation
Accompanying drawing is the drive circuit schematic diagram of a kind of Novel high-energy-saving LED street lamp with an automatic light meter.
Embodiment
As shown in drawings, IC2, C1, C2 and R1 composition capacitance-resistance voltage reduction circuit, it,, some the lower voltage of 220V values, sends to single phase bridge type rectifier circu rectification.C1 is controlled by relay normally open contact IC2, and in the time that IC2 disconnects, forming capacitance-resistance voltage reduction circuit by C2 and R1 provides AC power to rectification circuit; In the time that IC2 is closed, jointly forming capacitance-resistance voltage reduction circuit by C1, C2 and R1 provides AC power to rectification circuit.Choose C1=C2, then regulate R5 appropriate value, will realize LED street lamp with an automatic light meter after, on the basis of LED road lamp energy-saving, save again 50% electric energy.Rectifier circuit is made up of single phase bridge type rectifier circu, and its capacity is selected according to luminous plaque power.
As shown in drawings, SCR is unidirectional thyristor, and capacity is selected according to load.The trigger pulse width of unidirectional thyristor is controlled by single crystals brake tube T1 and peripheral resistance R 4, R5, C2, changes the value of R4, R5, C2, can change the ON time of unidirectional thyristor SCR within the cycle, thereby changes the brightness of LED street lamp.
Inductance L and capacitor C 1 that unidirectional thyristor SCR output connects form compound filter circuit, and it becomes the Rectified alternating current of thyristor SCR output into smoother direct current and supplies with LED lamp string.
As shown in drawings, T1, R2, R3, R4, R5 and C2 composition relaxation oscillator circuit, under the constant prerequisite of R2, R3, R4, by changing the value of adjustable resistance R5, can change the frequency of oscillation of relaxation oscillator, thereby change the conduction aperture of unidirectional thyristor SCR.
As shown in drawings, IC1 and peripheral circuit form the timer circuit of Novel high-energy-saving LED street lamp with an automatic light meter, the model of IC1 is CD4060, R6, C2 are electrifying self-resetting circuit, before self-resetting circuit, there is three terminal regulator IC3 circuit, it carries out filtering by filter capacitor C5 the Rectified alternating current of relaxation oscillation electrical equipment, then supplies with timer circuit working power through voltage stabilizing value of pressurizer output.Obtain electricity moment at LED street lamp, IC1's self-resetting circuit is resetted and timer counter starts, the now 3 end output low levels of IC1, cause the triode T2 of positive-negative-positive to become conducting from cut-off, relay IC2 adhesive, its normally opened contact IC2 closure, connects C1 loop, now, the electric current of circuit provides operating current with rated value to luminous plaque.
R7, R8, the C5 of IC1 peripheral circuit form long timing circuit, choose the value of R7, R8, C5 and pass through the effect of switching push button A, can the timing timing of 4-6 hour.
A driver for Novel high-energy-saving street lamp with an automatic light meter, chooses the parameter of C1, C2 in accompanying drawing circuit, T1, SCR element, just can drive the big or small LED street lamp of different capacity.
