Description

A kind of full automatic LED street lamp

Technical field

The present invention relates to a kind of full automatic LED street lamp.

Background technology

The LED street lamp using at present, the centralized power switch controlling outside being typically all by lamp of its work, with manually Or automatically operate.Control howsoever, the LED street lamp currently using, do not possess automatic Regulation function, cause LED road During lamp line voltage distribution superelevation in the second half of the night, LED street lamp can produce serious light decay, and even light fixture is burned sometimes.

Content of the invention

A kind of full automatic LED street lamp, its be meant that this light fixture on the premise of socket existing power supply, sky one is black, LED Street lamp can be turned on light automatically；After street lamp is lighted, the timer circuit in lamp is set timing, when the time counting setting Then, LED can automatic Regulation；By the time sky one is bright, and LED street lamp can be turned off the light again automatically.A kind of full automatic LED street lamp, it is simply that this Sample, hands off, and fully automatically carries out turning on light, pressure regulation, turns off the light, turns on light ... second after second circulation is carried out.

A kind of full automatic LED street lamp, its circuit structure has work main circuit and auxiliary circuit two parts.At the main electricity of work Lu Zhong, variable electronic component has capacitance-resistance voltage reduction circuit, the normally opened contact of its IC3 by two branch roads, C3 and IC6 normally opened Contact, C1 form capacitance-resistance voltage reduction circuit.Capacitance-resistance voltage reduction circuit has constant current-supplying characteristic, and the electric current of capacitance-resistance voltage reduction circuit is big Little determined by its capacitance.To this end, the variable circuit in work main circuit, it is variable is exactly under the control of auxiliary circuit Complete.As at dark, by the light-operated circuit effect in auxiliary circuit, capacitive branch in two capacitance-resistance voltage reduction circuits all connect Logical, form electric capacity parallel circuit.Capacitance-resistance voltage reduction circuit, with specified electric current supply LED street lamp work, makes at the illumination of LED street lamp In vehement bright operating mode；After LED street lamp is devoted oneself to work, long-time timing device is set timing, allow LED street lamp set Time period in irradiate road surface with vehement bright illumination.When setting time counting then, by the timer circuit of auxiliary circuit, resistance Hold the normally opened contact tripping of IC6 of step-down branch road, cut off electric capacity C1 branch road, the C2 that only normally opened contact of remaining IC3 is connected and R1 branch road.Owing to decreasing electric capacity C1, making the operating current of LED street lamp decrease a part, the illumination of LED street lamp is just by vehement bright Become secretly bright；By day, by the effect of light-operated circuit, in sky one firm bright when, just the IC3 of L line in light modulation operating mode Normally opened contact tripping.At this moment cut off the L line of alternating current, thus have turned off the working power of LED street lamp, it is achieved that automatically closed Lamp operates.

Brief description

Accompanying drawing is the circuit theory diagrams of a kind of full automatic LED street lamp.

Detailed description of the invention

As shown in drawings, the upper part in accompanying drawing circuit is main circuit, and it is by capacitance-resistance voltage reduction circuit, rectification circuit, compound Filter circuit and LED street lamp composition.In work main circuit, IC6, C1 and IC3, C2, R1 form capacitance-resistance voltage reduction circuit, are light fixtures Variable circuit in component.By day, due to the irradiation of available light, photo resistance VT1 in two light-operated circuits, VT2 resistance reduces, and the 2/6 pin current potential of IC2, the IC4 in light-operated circuit is more than 2/3U_CC, IC2 and IC4 all resets, and its 3 pin exports Low level.The 3 pin output low levels of IC2, make T1 end, IC3 is out of stock power supply and tripping, and its normally opened contact disconnects C1 branch road； The low level of the 3 pin outputs of IC4, makes IC5 not obtain power supply and quit work.Now, triode T2 is in cut-off state, and it is normally opened Contact disconnects C2, R1 branch road that IC6 is connected.I.e. by day, capacitance-resistance voltage reduction circuit is in and power end open state, LED street lamp Realize automatically turning off the light.

As shown in drawings, in accompanying drawing circuit, lower part circuit be auxiliary circuit, it is by two light-operated circuits and one Timer circuit forms.When shady deal is arrived, photo resistance VT1, VT2 resistance in light-operated circuit increases, IC2, IC4 the 2nd, The current potential of 6 pin is reduced to 1/3U_CCWhen, now, the equal set of IC2, IC4.IC2 set so that it is 3 pin output high level, drives IC3 to inhale Closing, its normally opened contact closes, and connects the resistance-capacitance depressurization branch road of R1, C2, and circuit connection state remains to daybreak, light-operated circuit Till reset LED street lamp；IC4 set so that it is 3 pin output high level, drives IC5 adhesive.12 pin of IC5 model are a powering up runback Position end, obtains the moment of electricity at IC5, and IC5 resets, and the 3 pin output low levels of IC5, timer timing simultaneously starts.Due to IC5 3 Pin output low level, makes the triode T2 of positive-negative-positive turn on, and drives IC6 adhesive, and its normally opened contact closes, and connects R1, C2 branch road. Now, two branch roads of capacitance-resistance voltage reduction circuit are all received on power supply, and are connected into parallel circuit, make circuit have the work of maximum Electric current supplies LED street lamp, completes operation of automatically turning on light.

As shown in drawings, the IC5 chip in accompanying drawing circuit, is the timer chip of a block length timing.Can by 10 pin of IC5 Adjusting ohmically R11, the time being timed device sets, and can set the timing setting of 4-6 hour.Arrive when setting time counting When, 3 pin of IC5 are high level output by low level upset, cause the triode T2 of positive-negative-positive to be become cut-off from conducting, IC6 also with Tripping, its normally opened contact IC6 cuts off C1 branch road.Now, capacitance-resistance voltage reduction circuit is only left C2, R1 branch road, decreases C1 electric capacity, The operating current making supply LED street lamp decreases, and LED street lamp is operated in the operating mode of dimming state.The 3 pin output height at IC5 During level, high level signal delivers to 11 pin of IC5 by D1, causes IC5 failure of oscillation, and this state is maintained to daybreak, by two Till light-operated circuit IC3, IC6 complete resection, LED street lamp is automatically performed pressure regulation operation like this.

As shown in drawings, V is piezo-resistance, and it plays one and prevents the paroxysmal high-voltage pulse of circuit from impacting, and protects LED Street lamp exempts from the effect of damage.D1 is switching diode, and model is 4148, plays guiding and buffer action in circuit.
