Description

A kind of intelligent type energy saving lighting controller

Technical field:

The utility model belongs to electronic technology field, is a kind of controller of controlling lighting brightness.

Background technology:

At present, Artificial Control is generally adopted in the control of its brightness of public lighting of building, for saves energy, during natural light intensity, closes some illuminating lamps, and energy-saving effect is not obvious, is inconvenient to operate, and result of use is not good.

Summary of the invention:

The technical problems to be solved in the utility model is to disclose a kind ofly by intelligent means public lighting to be controlled, thus the lighting controller of energy savings effectively.

The principle of Lighting Control Assembly is to carry out light modulation or close or open illumination as required.The master control power supply is made up of alternating current, and this electric current is to flow to a direction along transmission cable earlier, is turning to another direction then, and speed is per second 50 or 60 loops, if count with cps hertz (HZ).Frequency values is the network system that 50HZ or this frequency of 60HZ depend on the country one belongs to or area.

If we observe the waveform of alternating current, can find that its side is the S shape of stretching.As in the middle of waveform, drawing a line, Here it is so-called zero cross point.The implementation of light modulation is exactly will die morphotype piece or bi-directional thyristor switch shutoff, is opening after a period of time by zero cross point then.Long more during this period of time, just few more by the electric energy of module or bidirectional triode thyristor and inflow illuminating lamp, the light of illuminating lamp is also just dark more.When arriving the crosspoint (being commonly called as half-phase) of principal current, the switching speed of module or bidirectional triode thyristor is per second 100 times at every turn.

When lamp was carried out light modulation, the electric energy that can save was up to not using 98% of electric energy.Since human eye to light intensity to experience right and wrong linear, therefore just the brightness value grade of turning on light might being reduced in advance more than 10% at this moment, human eye is not aware of the brightness variation.So just can save 10% electric energy.If the light modulation gray scale is reduced by 50%, just at the electric energy that can save about 40%.Intelligent light regulator can gradually be transferred to lamp and preestablish rank.This is even more important when turning on light for the first time.Lamp gradually is transferred to preestablishes rank and be also referred to as " soft start " this can prolong the useful life of lamp greatly.The life-span of using 10% dim level can prolong lamp is got over twice, if adopt 50% dim level can prolong about 20 times useful life approximately.Also have voltage stabilizing function in the simultaneity factor, can protect fluorescent tube not damaged by the peak voltage in the main circuit.

The scheme of the utility model technical solution problem is to adopt drive circuit, signal acquisition circuit and executive circuit constitute the intelligent type energy saving lighting controller, drive circuit is by full-wave rectification bridge T4, the normal opened contact K1 and the K2 of relay J 1, voltage controlled oscillator TLC5551, potentiometer W1, driver module TLP250 and power output module IGBT constitute, wherein the normally opened contact K1 of relay J 1 connects the input of full-wave rectification bridge T4, the output of full-wave rectification bridge T4 connects 8 pin of driver module TLP250 by the normally opened contact K2 of relay J 1,7 pin of voltage controlled oscillator TLC5551 connect potentiometer W1, and passing through 2 pin that 3 pin connect driver module TLP250,7 pin of driver module TLP250 connect power output module IGBT drive signal input pin; Signal acquisition circuit is made of MCU1, MCU2, relay J 1, illuminance transducer, acoustic control transducer and thermal infrared sensor, wherein 18 of MCU1,17 are connected illuminance transducer, acoustic control transducer and thermal infrared sensor respectively with 16 pin, 20 pin of MCU1 connect relay J 1, MCU1's, 31 pin connect 11 pin of MCU2; Executive circuit is made of motor driver M54649L, stepping motor M1, wherein 3 pin of motor driver M54649L connect the A end of stepping motor M1, the B end of stepping motor M1 connects 10 pin of drive circuit, and drive signal control end 4,5,6 pin of motor driver M54649L are connected with 16,17,18 pin of MCU2.When MCU1 obtains open command, the 20 pin output high level of MCU1, relay J 1 adhesive, its normally opened contact K1 and K2 closure, full-wave rectification bridge T4 provides power supply to make it get electric work to voltage controlled oscillator TLC5551 and driver module TLP250, pass through power output module IGBT again with illumination lamp ignition, when MCU1 receives illuminance transducer, require the instruction of output control signal according to program setting during the signal of acoustic control transducer or thermal infrared sensor, through MCU2 and motor driver M54649L drive stepping motor M1 work, change the resistance of potentiometer W1, adjust voltage controlled oscillator TLC5551 frequency of oscillation, the control lighting brightness.

The utility model can reduce artificially waste effectively to the public lighting centralized management, and is with an automatic light meter, prolongs the useful life of light fixture, dependable performance, and saves energy 60-70% compares with common public lighting.
