Background technology
Lamp in current 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 the annexation of circuit interior joint change on demand, reach to lamp switch change purpose. This lamp controls the most simply, cost is also minimum, therefore commonly used in corridor in early days. But in use procedure, often occur that pedestrian turns on lamp at bottom of the building, the situation that after upstairs, but nobody turns off the light, waste very much electricity. It addition, the pedestrian on corridor must be well familiar with the switch arrangement position of each floor, being just unlikely to can not find switch night, this condition setting is very irrational, has too many people to be unfamiliar with after all. On the basis of conventional push button, occur in that the hand touch switch of improvement, it is simply that touch sensible.

Operation principle is as follows:
First L end and N end are connected on 220V power supply, after connecting 220V voltage, 220V voltage is through electric capacity C1 blood pressure lowering, through the D1-D4 bridge rectifier output ripple voltage formed, after electric capacity C2 filters, output DC voltage divides two-way, and a road DC voltage is connected to by the positive pole luminous for LED1 of 7 LED series connection; Another road voltage exports 12V voltage after R1 resistance blood pressure lowering, VD1 stabilivolt voltage stabilizing, C3 capacitor filtering and powers to audio-switch control circuit.
Under static holding state:
MK1 Electret condenser microphone no signal inputs, audion Q1 is in static magnifying state, because resistance R3 resistance 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 makes Q3 audion be also at by state by, Q4 audion, and the LED of LED1-LED7 series connection is not luminous because of no-voltage.
When extraneous intensity of illumination is enough, VR1 photoconductive resistance is low impedance state, even if short circuit C5 electric capacity, the base stage of Q2 audion also can not get enough conducting voltage, and now, Q3, Q4 audion is still in by state, and 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 condition, but because C4 electric capacity every straight effect, 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, and the LED of LED1-LED7 composition does not still work.
When extraneous intensity of illumination is more weak and by acoustical signal:
VR1 photoconductive resistance is high impedance status, may be regarded as VR1 compared with R6 resistance is open-circuit condition, MK1 Electret condenser microphone output audio signal is capacitively coupled to Q1 audion through C4, the high audio signal of amplitude is created by C5 Capacitance Coupled at its colelctor electrode after Q1 audion amplifies, through D5 and D6 diode halfwave rectifier, DC voltage base stage to Q2 audion after R5 and R6 electric resistance partial pressure is exported after C6 capacitor filtering, make Q2 triode ON, 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 significantly high and acoustical signal has certain persistent period, C7 electric capacity during this period of time can be fully charged, make Q3 triode ON, Q4 triode ON, the LED1-LED7 LED formed is made to obtain electroluminescence. and electric capacity C7 is relatively larger to emitter stage discharge time constant by resistance R7 to Q3 transistor base, Q4 audion is made to tend to remain on, until the undertension on C7 is so that Q3 triode ON, Q4 audion by, the LED of LED1-LED7 composition does not work, reaching acoustic control to turn on light, time delay is turned off the light, thus reaching using electricity wisely.
