Description
Technical field
This utility model relates to lighting technical field, is specifically related to a kind of sound and light controlled delay switch energy-saving LED
Corridor lamp.
Background technology
At present the lamp in corridor, has various on-off control mode, including: conventional push button, hand touch switch,
Sound switch.Use conventional push button control, it is simply that pure physics stress react, slightly with defeat by, make electricity
The annexation of road interior joint changes on demand, reaches the purpose to lamp switch conversion.This lamp control
System is the simplest, cost is minimum, commonly used in corridor the most in early days.But during Shi Yonging, warp

Button and hand touch switch be the most advanced how.It is by sound transducer, and acoustical signal is converted into telecommunications
Number go to control the circuit conversion of lamp.But, there is daytime people through corridor or to have other inhuman sound walked about
Time (sound etc. such as spruced up), lamp all can be made to open.By disturbing of the inhuman sound walked about, sound
Control switch switchs continually, greatly reduces service life, wastes the most very much electricity, and this is not the most us
Desired.

Operation principle is as follows:
First L end and N end being connected on 220V power supply, after connecting 220V voltage, 220V voltage is through electricity
Hold C1 blood pressure lowering, the bridge rectifier output ripple voltage formed through D1-D4, after electric capacity C2 filters
Output DC voltage divides two-way, and it is luminous that a road DC voltage is connected to the LED1 by 7 LED series connection
Positive pole；Another road voltage exports 12V after R1 resistance blood pressure lowering, VD1 stabilivolt voltage stabilizing, C3 capacitor filtering
Voltage is powered to audio-switch control circuit.
Under static holding state:
MK1 Electret condenser microphone no signal inputs, and audion Q1 is in static magnifying state, because resistance R3 resistance
Value is very big, also have because electric capacity C5 every straight effect, Q2 audion no-voltage and be in by state, Q2
Transistor emitter Non voltage output make Q3 audion by, Q4 audion is also at by state,
The LED of LED1-LED7 series connection is the most luminous because of no-voltage.
When extraneous intensity of illumination is enough, VR1 photoconductive resistance is low impedance state, though short circuit C5 electric capacity,
The base stage of Q2 audion also can not get enough conducting voltage, now, Q3, Q4 audion still in by
State, LED does not still work.
When extraneous intensity of illumination is more weak and during voiceless sound signal:
VR1 photoconductive resistance is high impedance status, compared with the resistance of R6 resistance, can be considered that VR1 is open circuit shape
State, but acting on every straight because of C4 electric capacity, Q2 transistor base no-voltage, still in by state, causes
Q3 audion still by, still no-voltage on C7 electric capacity, Q4 audion is also still in by state, LED1-LED7
The LED of composition does not still work.
When extraneous intensity of illumination is more weak and by acoustical signal:
VR1 photoconductive resistance is high impedance status, and may be regarded as VR1 compared with R6 resistance is open-circuit condition, and MK1 stays
Electret microphone output audio signal is capacitively coupled to Q1 audion through C4, at Qi Ji after Q1 audion amplifies
Electrode creates the high audio signal of amplitude and passes through C5 Capacitance Coupled, through D5 and D6 diode halfwave rectifier,
Export DC voltage base stage to Q2 audion after R5 and R6 electric resistance partial pressure after C6 capacitor filtering, make Q2 tri-
Pole pipe conducting, Q2 transistor collector output 12V voltage, charge to electric capacity C7 after D7 diode current flow,
Owing to the frequency of audio signal will not be the highest and acoustical signal has certain persistent period, C7 electric capacity is at this
Can be fully charged in the section time, make Q3 triode ON, Q4 triode ON, make LED1-LED7 form
LED obtain electroluminescence.And electric capacity C7 is normal for discharge time to emitter stage by resistance R7 to Q3 transistor base
Number is bigger, makes Q4 audion tend to remain on, until the undertension on C7 is so that Q3 audion is led
Logical, Q4 audion by, the LED of LED1-LED7 composition does not works, and reaches acoustic control and turns on light, and time delay is turned off the light,
Thus reach using electricity wisely.
