Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, with reference to embodiments, to this
Utility model is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain this practicality
It is novel, it is not used to limit the utility model.
Below in conjunction with the accompanying drawings and specific embodiment is further described the application principle of the utility model.
Comparative example, such as Fig. 1, a kind of double light-operated driving control systems of induction LED, including AC input module 1, EMI modules 2,

It flows filter module 3 and enters comparator control module 4, then switch original paper J action control drive controls are made by comparator control module 4
Module 5 is again by the 5 to the second rectification filtering module of drive control 6, by loading LED load module 7 to the second rectification filtering module 6.
Its light-operated sensing control section is：When ambient brightness reduces at dark, the raising of RH resistance values makes the reduction of A points current potential, when
Dropping to certain value, both this photo sensor device of critical point RH induces low signal, and into comparator, high RST is exported by comparator
Control triode Q1 and metal-oxide-semiconductor Q2 is gone to act switch original paper J and is powered on to illuminate load LED to drive control.When at day environment
Brightness increases, and sensing RH makes A point current potentials be increased to more than critical point, and comparator output low level makes triode Q1 and metal-oxide-semiconductor Q2
Cut-off makes switch original paper J that drive control dead electricity load LED be blocked to extinguish.
Photo sensor device RH senses A points current potential there are one critical point in this circuit, and ambient brightness is less than A points
Critical point, comparator C points output high RST light load, and load at this time makes ambient enviroment brightness rise this brightness quilt again after lighting
Photo sensor device RH absorptions make its A point not only higher than critical point comparator C points but also output low potential extinguishes load immediately, load
Ambient enviroment brightness reduces RH A point current potentials is made to be increased to critical point and load is made to light again, is so passed through in cycles again after extinguishing
Ambient brightness thoroughly grows dark and can just settle out after a period of time.It is usually to add a positive feedback on comparator to overcome this phenomenon
Device R.When ambient brightness make A points as low as critical point comparator C output high level light load simultaneously C points high level it is anti-through R
Being fed to the input positive terminal of comparator makes reference potential raising 30-40 ℅ to overcome because load self brightness increases to what A points were brought
Current potential.But this feedback can only reach 40 ℅ again it is high will feedback out of hand and 40 ℅ be that cannot thoroughly change critical overturning both
It cannot meet the requirements.
Embodiment 1, such as Fig. 2, a kind of double light-operated driving control systems of induction LED, including AC input module 1, EMI modules 2,

Block 7.
Main circuit is identical with Fig. 1 in addition to comparator controls module 4, only changes comparator control mode.This utility model
Control structure include comparator using it is double relatively, increasing light-operated inductor RH2 becomes double sensing RH1 and RH2.Q1 reconfigurations arrive down
The output terminal of comparator increases silicon-controlled VS and connects comparator output terminal.Its control principle is：
Adjustment R1 makes comparator A points current potential reach critical point as light-operated inductor RH1 in the increasing of its resistance value at dark, this
When comparator C points output high level control silicon-controlled VS conductings, so as to which switch original paper J actions be made to light load LED, due to controllable
Even if silicon characteristic conducting after signal out of hand it remain on, not by because load self brightness influenced to be always maintained at
Conducting state.Adjustment R2, which makes its load light the critical point that B points current potential can not be made to be less than lower comparator, at this time is in D points
High level, this assures load LED to stablize illuminating state, is not influenced by load self brightness variation.When time daybreak
Although quick inductor RH1 makes critical point of the A points current potential more than upper comparator but since silicon-controlled performance load is in a little
Bright state.RH2 resistance values at this time reduce in daylight environment brightness plus the sensing resistance value for loading the brightness of itself, when being reduced to one
Definite value makes lower comparator B points current potential reach or less than critical point, and the high level of D points output at this time makes triode Q1 conductings silicon-controlled
VS current potentials, which move ground terminal to, forces silicon-controlled VS shutdowns that switch original paper J dead electricity is made to extinguish load LED.Later Zhou Dynasty, one of the Five Dynasties's collarette is extinguished in load at this time
Even if border brightness decreases, B points postcritical obtains D points output low potential triode Q1 turn off thyristor VS current potentials extensive
Again but since upper comparator A points are that the high potential C points output silicon-controlled VS of low potential can not be connected, load still in extinguishing shape
State.Only wait until that darkness RH1 makes A point current potentials drop to critical point and could light again.So just solves the bistable of product
State.
