Description

The photoacoustic dual-controlled energy-saving electronic switch

The utility model belongs to the electronic switch field, particularly a kind of photoacoustic dual-controlled energy-saving electronic switch.

At present, most of energy-saving electronic switch are made up of integrated circuit or discrete electronic component, and by the circuit that integrated circuit is formed, though have the good characteristics of performance, cost is higher, are difficult for promoting; And the circuit that discrete electronic component is formed because circuit is too simple, is difficult for the effect that obtains again.

The purpose of this utility model is, designs a kind of novel photoacoustic dual-controlled energy-saving electronic switch, adopts time-base integrated circuit to cooperate with triode, forms hybrid circuit, makes it have sound, light and pair controls, and delay function is arranged.

Photoacoustic dual-controlled energy-saving electronic switch of the present utility model, form by housing, control circuit, it is characterized in that: control circuit comprises sonic transducer, optical sensor, decision circuit, delay circuit, drive circuit and load, sonic transducer that constitutes by pickup transmitter and the optical sensor that constitutes by phototriode with by transistor BG ₁, BG ₂The decision circuit of forming connects, and delay circuit one end and the decision circuit that are made of time-base circuit 555 connect, and the other end connects with the drive circuit that is made of controllable silicon SCR, and load is connected on the drive circuit;

Between sonic transducer and phototriode, be provided with potentiometer W, between sonic transducer and potentiometer, be provided with capacitor C ₁, be provided with C between potentiometer and the phototriode ₂, decision circuit BG ₁, BG ₂Between be provided with capacitor C ₃Isolate, between drive circuit and load, be provided with the regulator rectifier circuit of forming by C, D, DW.

Photoacoustic dual-controlled energy-saving electronic switch of the present utility model, occupation mode be, as the DT, because the effect of illumination, when audible signal, electronic switch can be closed, promptly can not the ignition circuit load, as corridor lamp etc.; And under the darker situation of night or weather, then can pass through acoustical signal, as voice, heavier footsteps, auto-closing electronic switch, ignition circuit load such as corridor lamp etc.; After electronic switch closes, also can automatic time delay 10-60 second, open electronic switch again, make circuit load lose electric energy, will close as corridor lamp and to extinguish, not produce the misoperation of lighting light daytime thereby be implemented in, night is very convenient in the time of need opening electronic switch, and the dead of night, but automatic shutdown circuit thereby produce fairly obvious energy-saving effect again.

The course of work of photoacoustic dual-controlled energy-saving electronic switch of the present utility model is: during daytime, and phototriode GG conducting, the transistor BG of decision circuit ₁End, make the sonic transducer signal can not enter the back level; At night, then photosensitive biography triode is high-impedance state, makes BG in the circuit ₁Can receive the sonic transducer signal and transmit subordinate; Time-base circuit adopts 555, plays delay function, discharges automatically after prolonging a period of time again after the closing of circuit load, has so both made things convenient for the user, can play energy-conserving action again, the transistor BG of decision circuit ₂Form typical AC amplifier, improved sensitivity greatly, directly control the trigger electrode of time-base circuit 555; Drive circuit adopts bidirectional triode thyristor SCR directly to form zero cross fired by 555, entire circuit again by capacitor C from the civil power step-down, and form regulator rectifier circuit by rectification diode D, voltage-stabiliser tube DW; The potentiometer that is provided with in decision circuit can adjust the power of two paths of signals according to the difference of device, and entire circuit is by capacitor C ₁, C ₂, C ₃Isolate, form to exchange the amplification mode.Therefore, the relevant interference of this circuit is depressed into minimum.Sonic transducer adopts pickup formula microphone, and is highly sensitive, be easy to organize circuit, and cost is low.

Photoacoustic dual-controlled energy-saving electronic switch of the present utility model has stable performance, and the advantage of reliable operation, and cost is low is easy to make, and can be widely used in illumination control and as the multifunction switch of other purposes.

Below in conjunction with drawings and Examples, the photoacoustic dual-controlled energy-saving electronic switch is described further.
