Working principle: when having voice signal around this, MIC will amplify after audible signal reception through sound control circuit, then pass through
Rectification circuit is changed into voltage signal and is passed in light-operated circuit.When there is illumination to impinge upon in the photo resistance in light-operated circuit,
Prevention becomes smaller, and decays very big to direct-current control voltage, electronic switch is caused to be in off state.At this moment delay circuit will not work
Make, make unidirectionally can silicone tube be in off state, light bulb does not work.When there is no light delay circuit work, make unidirectionally can silicone tube conducting,
Alternating-current switch is controlled simultaneously, light bulb is bright.
This circuit is that an acousto-optic automatically controls filament lamp switch.When daytime or brighter night light, light-operated part will be opened
Pass is automatically shut down, and acoustic control part does not work.Circuit is mainly by 555 integrated circuits and acoustic control specific integrated circuit BH-SK-I group
At.When daytime or brighter night light, light-operated part automatically shuts down switch, and acoustic control part does not work.Work as dark
When, light-operated part automatically opens switch, and the on-off of load circuit is controlled by acoustic control part.Whether circuit is connected, and sound is depended on
Sound signal intensity.When the sound intensity reaches a certain level, circuit turn on automatically lights incandescent lamp, and trigger, delay time
It arrives, switch is automatically shut down, and waits voice signal triggering next time.
1. light bulb does not work when voiceless sound is without light
There is no sound around acousto-optic control illumination power saving switch, circuit is in off position when photo resistance no light,
Light bulb will not work.
2. light bulb does not work when voiceless sound has light
There is no sound around acousto-optic control illumination power saving switch, circuit is in off position when photo resistance has illumination,
Light bulb will not work.
3. light bulb does not work when having sound to have light
Off position will be not at when not having sound around this circuit.When only having sound around this circuit, MIC
It will amplify after audible signal reception through VT1, then rectified circuit VD1, VD2 are changed into voltage signal and are passed in photosensitive circuit.?
When photo resistance RGM is had in illumination in photosensitive circuit, resistance value becomes smaller, and is equivalent to the effect of conducting wire, declines to direct-current control voltage
Subtracting causes very greatly the electronic switch of VT2, VT3 and R7, VD3 composition to be in close state, and does not have signal stream and enters junior's circuit
In, to make one-way SCR MCR be in off state without charge in C4, therefore light bulb will not work.
Have sound it is unglazed when light bulb it is bright
When having sound around this circuit, MIC will amplify after audible signal reception through VT1, then rectified circuit VD1, VD2
Be changed into voltage signal be passed to photosensitive circuit in, when it is unglazed be radiated at photo resistance RGM when, RGM resistance value is very big, is equivalent to open circuit
State, to direct-current control voltage decaying very little.The electronic switch conducting of VT2, VT3 and R7, VD3 composition, make capacitor C4 start to fill
Electricity.Rapidly due to the fully charged time, full of direct current trigger voltage is added to MCR control terminal by R8 after charge, MCR is led C4
It is logical, light light bulb.When charge is put to zero in C4, MCR restores off state, and light bulb extinguishes at this time.
When having new sound source to go out new in light bulb ignition, C4 can recharge rear re-discharge, that is, recalculate a little
The bright time.It is about 30 seconds or so that light bulb, which lights duration,.If necessary to change the bright duration of lamp, it is only necessary to change the parameter of C4 or R8
?.
Thyristor wants work and has to just be connected when gate leve adds forward voltage, in the case where thyristor is in the conductive state
When, when only major loop is reduced to close to zero, thyristor can just be turned off, so this circuit will reach carryover effects and have to protect
It is in the conductive state under a period of time to demonstrate,prove thyristor.Therefore the capacitor C4 before thyristor plus a 100uF is filled
Electric discharge.And trigger voltage is added to crystalline substance by R8 by the charging circuit formed when VT3 collector is by electric signal outflow through VD3, C4
Brake tube MCR control terminal can just turn it on.And R8, C5 and unidirectionally controllable MCR, VD5-VD8 composition delay and alternating-current switch control
Make the light on and off to determine light bulb.Delay time t is determined by the parameter of C4, R8 in the design.The calculating of its time t:
。
It is not to grow very much since the light bulb of needs continues lighting time, general 20-30 seconds or so, it is contemplated that with an electricity
Hold the state of control switch.When having sound around MIC, when no light, when electronic switch is opened, C4 connection starts
Charging；After electronic switch is closed, C4 starts to discharge.C5 is as anti-interference capacitor in figure, for eliminating light bulb trembling when shining
Dynamic phenomenon.
