Induction automatic switch of the present utility model, it can be applicable to corridor, corridor or health intercropping luminous lamp switch, during use, the normally open contact of this switch repeat circuit is attempted by former illuminating lamp switch ends, thus the automatic control function of realizing people Lai Dengliang, turning off the light when you leave.

Accompanying drawing explanation

Fig. 1 is the circuit diagram of a kind of embodiment of the utility model.

Embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:

With reference to figure 1, a kind of induction automatic switch, it comprises music integrated circuit IC, relay K 1, control transistor V, resistance R 1, resistance R 2, potentiometer RP, voltage stabilizing didoe VS, rectifier diode VD, switch S, illuminating lamp EL and the normally open contact K1-1 of induced electricity pole piece A, technotron VF, KD9300 type, the gate pole of described technotron VF connects induced electricity pole piece A, the drain electrode of technotron VF is connected 6V power supply by resistance R 1 successively with switch S, the source electrode of technotron VF connects 2 pin of the music integrated circuit IC of KD9300 type; 1 pin of the music integrated circuit IC of KD9300 type is connected 6V power supply by resistance R 1 successively with switch S, 3 pin connect the base stage that controls transistor V, 5 pin ground connection; The anode tap ground connection of voltage stabilizing didoe VS, the cathode terminal of voltage stabilizing didoe VS connects 1 pin of the music integrated circuit IC of KD9300 type; A resistor wiring end of potentiometer RP connects 7 pin of the music integrated circuit IC of KD9300 type by resistance R 2, the slide terminals of another resistor wiring end and potentiometer RP are all connected 6 pin of the music integrated circuit IC of KD9300 type; The emitter of controlling transistor V connects 6V power supply by switch S, controls the collector electrode of transistor V by relay K 1 ground connection; The anode tap ground connection of rectifier diode VD, cathode terminal connects the collector electrode that controls transistor V; One end of illuminating lamp EL connects 6V power supply, and the other end connects normally open contact K1-1.

Operation principle of the present utility model: at ordinary times, the 3 pin absence of audio signal outputs of the music integrated circuit IC of KD9300 type, control transistor V cut-off, and relay K 1 is failure to actuate, and illuminating lamp does not work.When having people through corridor, corridor or entering toilet, the induced signal of human body is sent into technotron VF grid through induced electricity pole piece A (being arranged on the porch in corridor, corridor or the door limit of toilet), make the resistance between its drain electrode and source electrode become large, 2 pin (trigger end) at the music integrated circuit IC of KD9300 type produce trigger impulse, music integrated circuit IC is subject to triggering work, from the audio signal of 3 pin outputs, make to control transistor V saturation conduction, relay K 1 adhesive, its normally open contact K1-1 connects, and illuminating lamp EL is lit.

The time of lighting of illuminating lamp EL is determined by the musical time storing in the music integrated circuit IC of KD9300 type, when bent an end of a period, controls transistor V cut-off, and relay K 1 discharges, and illuminating lamp EL extinguishes.The suitable resistance of regulator potentiometer RP, can change the playing music the time of music integrated circuit IC of KD9300 type, thereby change lighting the time of illuminating lamp EL.

Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should think protection range of the present utility model.
