Description

The light-operated automatic lighting switch of infrared induction

The utility model relates to the light-operated automatic lighting switch of a kind of infrared induction, belongs to illuminating lamp automatic control switch technical field.

At present, illuminating lamp automatic control switch of the prior art generally all adopts acoustic control or light-operated method to control automatically.Its shortcoming of light-operated lighting automatic switch is under nobody's situation, and it is luminous up to daytime that its switch still keeps illuminating lamp to continue, and therefore this light-operated automatic switch is not suitable for corridor lighting; Though and the advantage that audio-switch is closed when having nobody automatically, even but daytime, as long as sound is arranged, its switch will be opened automatically, so just wasted electric energy in vain, and audio-switch be because will there be certain sound just can connect, and is a kind of noise the people of these sounds in staying in building, and therefore existing lighting automatic switch in use and not really desirable.

The purpose of this utility model is: as long as providing a kind of can automatically shut down by day, have the people the light-operated automatic lighting switch of infrared induction of illuminating lamp to occur can connecting automatically without sounding on night, to overcome the deficiencies in the prior art.

The utility model is to constitute like this: it comprises shell (1) and circuit board (2), circuit board (2) is contained in the shell (1), on shell (1), be provided with loophole (3) and infra-red detection hole (4) and three terminals a, b, c, pyroelectricity formula infrared detection head module I C1 is housed on circuit board (2), time-base circuit module I C2, photo resistance RG, triode V1, controllable silicon V2, resistance R 1～R4, capacitor C 1～C4, diode VD1 and VD2 and voltage-stabiliser tube VD3, the anode of V2 meets C1 and terminals a, the positive pole of another termination VD1 of C1 and the negative pole of VD2, the negative electrode of V2 meets terminals c, the control utmost point of V2 meets R4 and C4, the output of another termination IC2 of R4, collector electrode and the R2 of the input termination V1 of IC2, the base stage of V1 connects the signal output part of IC1 by R1, the anodal termination R2 of IC1, IC2, R3, C2, the positive pole of VD3 and the negative pole of VD1, the emitter of the negative pole termination V1 of IC1, the negative pole end of IC2, be connected the C3 on the IC2, RG, C4, C2, the negative pole of VD3, the positive pole of VD2 and terminals b, a control end and the R3 of another termination IC2 of RG, the phase line of the AC power of 220V is connected on the terminals a, its neutral line is connected on the terminals b, and illuminating lamp ZD is connected on terminals b and the c.

Owing to adopted technique scheme, the utility model compared with prior art, the utlity model has and to automatically shut down switch by day, even someone illuminating lamp energising occurs also can not making, as long as and have the people to occur can connecting illuminating lamp automatically and making the advantage of illuminating lamp time-delay certain hour energising on night without sounding; The utility model also has simple in structure, with low cost, stable and reliable operation advantage in addition.Operation principle of the present utility model is: when daytime is bright, be low resistive state when RG is subjected to illumination, IC2 is reset and output low level, not conducting of V2, ZD does not work, when light is dark, RG is a high-impedance state, but at this moment reset signal is invalid, if there is the people to walk close to, as long as reach effective range, IC1 just exports high level, and the V1 conducting makes IC2 output high level, the V2 conducting, ZD is bright; If in the infrared induction effective range, IC1 just exports high level to the people, makes V2 conducting always always always, ZD is bright always, if the people leaves the infrared induction effective range, IC1 is with regard to output low level, and V1 ends, make the IC2 output low level, end through V2 behind the certain hour, ZD extinguishes.
