Abstract

Late at night, pedestrians are less, but various road lamps and lighting lamps are also in full power lighting. For saving electrical energy, a half-power automatic generator for a road lamp is designed. The utility model is connected with a power supply loop of the road lamp in series. After the road lamp is turned on for a plurality of hours (the time can be adjusted.), the utility model automatically and smoothly turns to lower power output (the power can be adjusted.). The utility model is provided with a detecting gear, and the functions of the whole generator can be detected at any time. The utility model is provided with a reset button, and the low power can be optionally turned to full-power output. The utility model has the advantages of small size, large power, continuous conversion and no spark, and is a favorable energy-saving device.

Description

Street lamp half-power automatic generator

The utility model draws and a kind of energy saver of street lamp power supply, road lamp power supply, especially a kind of night, street lamp was unlocked, total power is lighted (time is adjustable) after a few hours, and just automatic smoothing changes low-power output (adjustable power) over to, makes the street lamp half-power automatic generator of street lamp brightness step-down.

At present, street lamp, especially each residential quarters, residential block, park, the inside and outside street lamp of office building institute, all be brilliantly illuminated night.Particularly be still the total power illumination after the late into the night, add line voltage height at night, brightness is brighter.And actual the requirement is: in the late into the night, pedestrian's rareness need not highlight illumination, as long as the low-light level illumination.At present, also do not find a kind of energy saver that makes street lamp reduce by half, be convenient to penetration and promotion to the automatic step-down of power in the late into the night, brightness.

The purpose of this utility model provides a kind of street lamp half-power automatic control equipment, and it is connected in the street lamp power supply, road lamp power supply loop.Night, after people open street lamp, total power output.When lighting street lamp, the control circuit trigger, after a few hours of delaying time, automatic smoothing changes low-power output over to, offers street lamp with lower-wattage.Saved electric energy.The delay time of a few hours can be selected, may command; But power output regulated at will.

The purpose of this utility model is achieved in that

The controller profile is a box body.Four lead-out wires are arranged: two are incoming line, get access to grid; Two is output line in addition, connects road lamp.

Four indicator lights are arranged on the box body panel, be respectively: AC power input indication, low-voltage control power indication, total power output indication and low-power output indication.A delay selection band switch is arranged: wherein first grade is " test " shelves, dials at " test " shelves, connect load and power supply after, in 1 minute, complete machine is exported by total power and is converted to low-power and exports.These shelves can be used to differentiate whether complete machine kinetic energy is intact.All the other shelves are selected shelves for delay time.A street lamp brightness regulator potentiometer is arranged, can artificially regulate power output.Also have a reset button, click this button, the half-power controller can change total power output over to from low-power immediately.

Circuitry is made up of control loop and major loop.

Control loop is made up of with indicating circuit and low-tension supply time base and frequency dividing circuit, reset circuit, delay selection circuit, master control.Major loop is made up of total power output circuit and power conversion circuit.

Reset circuit is made up of Resistor-Capacitor Unit and shaping circuit and push-button switch.After the start energized, export a low pulse, give counter and each trigger zero clearing; Click reset button, export a low pulse equally and give each trigger zero clearing, reach the purpose of total power output.

The Shi Jiyu frequency dividing circuit is made up of 14 grades of cascaded carry binary counter/frequency dividers, oscillators.The cycle of oscillating impulse can realize by regulating Resistor-Capacitor Unit.By frequency division, can provide the binary pulse output to a few hours in tens of seconds.This circuit takes out three time signals from frequency divider: one is the short time signal, is used for " test "; Two is long-time signal in addition, is used for time-delay control.

The rising edge of three time signals is respectively applied for and triggers three d type flip flops.Whether each d type flip flop is effectively triggered then determines by its D end which grade decision the D terminal potential is dialled in by the delay selection switch again.These three d type flip flops need only arbitrary road output high level, all can trigger the d type flip flop of master control and indicating circuit, make its output high level, the output of indication low-power.At first, the d type flip flop of master control and indicating circuit is cleared, the Q output low level, and Q exports high level, and this high level removes to drive zero cross fired photoelectricity coupling two-way controllable silicon in the major loop after the triode Current Control, make its conducting.After time-delay a period of time, after the d type flip flop of master control and indicating circuit is triggered set by the rising edge of arbitrary delay selection circuit, Q end output high level, Q output low level.This low level is ended triode, and zero cross fired photoelectricity coupling two-way controllable silicon loses electric current and closure in the major loop.

In the major loop, after the photoelectrical coupler conducting, trigger SCR ₁Bidirectional triode thyristor produces total power output.

In the major loop, after the photoelectrical coupler closure, electric main alternately charges to storage capacitor through power adjustments potentiometer, current-limiting resistance, when voltage reaches the conducting voltage of bidirectional diode, and two-way two utmost point conductings.Change the resistance of potentiometer, promptly regulated the angle of flow, thereby removed to trigger this SCR equally ₁Bidirectional triode thyristor has been realized low-power output.

Therefore, this circuit creatively combines total power and low-power output circuit dexterously, zero cross fired, seamlessly transits, and has realized the free of discontinuities of total power to the low-power conversion, the street lamp process of starter again when having avoided conversion.

This street lamp half-power automatic generator, 1. volume is little: can be installed in the lamp stand of any street lamp; 2. power is big: select the bidirectional triode thyristor of different capacity, can satisfy the needs of several or tens of street lamps; 3. " test " shelves are arranged: can check the complete machine function at any time; 4. " resetting " key is arranged: but the output of voluntary recovery total power; 5. the delay time scalable can be selected; 6. total power is level and smooth to the low-power conversion, free of discontinuities, contactless, no-spark.This is a street lamp, especially a kind of good energy-conservation device of the inside and outside and big or middle enterprises street lamp in residential quarters, residential block, office building institute.

The utility model is not only applicable to street lamp, and is applicable to the illuminating lamp that other need be lighted whole night.

If at regular tap of an end adjunction of the utility model main circuit power regulator potentiometer, so, when this switch disconnected, the utility model just became an accurate long-time delay controller, when photoelectrical coupler ends, just closed load.Which this delay controller need light the power consumption equipment of closing automatically after a few hours applicable to.As shop advertising lamp in front of the door etc.
