Description

A kind of public lavatory illuminating lamp sonic-opticalcon trolled switch circuit

Technical field

The utility model relates to lighting lamp control circuit, particularly a kind of public lavatory illuminating lamp sonic-opticalcon trolled switch circuit.

Background technology

Existing many offices, the passageway of the units such as school, stair, the sonic-opticalcon trolled switch that toilet lamp place uses controls street lighting, usual existence two kinds of extreme cases, or be poor sensitivity, or be too sensitive, on that night, extraneous one had sound of movement, namely illuminating lamp is triggered, or namely the bright rear general time delay of lamp extinguishes for 1 ~ 2 minute, when needs public lavatory occasion needs the long period, cause inconvenience, based on this, many public lavatorys also often adopt traditional switch key, easily there is the situation forgetting light-off, cause the waste of the energy, and the long-time frequency of utilization of switch key, easily cause damage, shorten its useful life.

Utility model content

For deficiency of the prior art, the utility model provides a kind of structure simple, rationally novel in design, the public lavatory illuminating lamp sonic-opticalcon trolled switch circuit that result of use is good, employing snap switch of setting foot on matches with acousto-optic controlled circuit, stable, reliable, with the obvious advantage, Be very effective.

According to design provided by the utility model, a kind of public lavatory illuminating lamp sonic-opticalcon trolled switch circuit, comprise photosensitive detection circuit, sound intensity testing circuit, signal processing circuit, power circuit, voltage stabilizing circuit and sound light control circuit, sound intensity testing circuit is connected with sound light control circuit by the snap switch K that sets foot on, the snap switch K that sets foot on is connected with illuminating lamp LAMP1 by signal processing circuit, sound light control circuit comprises triode VT2, triode VT3, thyristor BT1, signal processing circuit comprises the rectification circuit be connected with power circuit, to set foot on the delay circuit being also connected with between snap switch K and sound light control circuit and being made up of resistance R3 and electric capacity C3.

Above-mentioned, sound intensity testing circuit comprises acoustic control miaow head MIC1, triode VT1.

Above-mentioned, rectification circuit is the full bridge rectifier be connected into by four rectifier diodes.

Above-mentioned, power circuit is connected with 220V AC power.

The beneficial effects of the utility model:

The utility model novel in structural design, rationally, structure is simple, by set foot on snap switch and delay circuit and acousto-optic controlled circuit with the use of, stable, reliably, avoid the waste of the energy, economize on resources, the useful life of raising illuminating lamp.

accompanying drawing illustrates:

Fig. 1 is schematic diagram of the present utility model;

Fig. 2 is circuit theory diagrams of the present utility model.

embodiment:

Below in conjunction with accompanying drawing and technical scheme, the utility model is described in further detail, and describes execution mode of the present utility model in detail by preferred embodiment, but execution mode of the present utility model is not limited to this.

Shown in Fig. 1 ~ 2, a kind of public lavatory illuminating lamp sonic-opticalcon trolled switch circuit, comprise photosensitive detection circuit, sound intensity testing circuit, signal processing circuit, power circuit, voltage stabilizing circuit and sound light control circuit, sound intensity testing circuit is connected with sound light control circuit by the snap switch K that sets foot on, the snap switch K that sets foot on is connected with illuminating lamp LAMP1 by signal processing circuit, sound light control circuit comprises triode VT2, triode VT3, thyristor BT1, signal processing circuit comprises the rectification circuit be connected with power circuit, to set foot on the delay circuit being also connected with between snap switch K and sound light control circuit and being made up of resistance R3 and electric capacity C3, by set foot on snap switch and delay circuit and acousto-optic controlled circuit with the use of, stable, reliably, avoid the waste of the energy, economize on resources, improve the useful life of illuminating lamp.

Above-mentioned, power circuit is connected with 220V AC power.

As shown in Figure 2, by day, photo resistance R11 conducting, at this moment no matter whether acoustic control miaow head triggers, and whether K switch (K is snap switch of setting foot on, and can be arranged on the foot pedal of stool) is connected, the ground level ground connection of triode VT2, VT2VT3 ends, thyristor BT1 Triggerless and turning off, and at this moment lamp does not work; To evening, the colour of sky is dim, and R11 resistance increases, but if MIC1 does not receive voice signal, or the ground level of K disconnection (nobody steps on) VT2 does not still have voltage, and circuit disconnects, and lamp does not work; Think that toileting person has come if had evening, about 2 ~ 3 meters to MIC1 (being contained on the outer beam in lavatory) voice signal (clap the hands or roar), at this moment voice signal amplifies to BT1 mono-triggering after C2 lotus root conjunction VT2 has had base voltage conducting to amplify through VT1, and BT1 conducting lamp is bright; If someone defecates, step on foot pedal K, the snap switch K that will set foot on connects circuit, and to VT2 whole circuit ON of base voltage, lamp is bright, and simultaneously in delay circuit, electric capacity C3, resistance R3, can delay times under resistance R12 coordinates, and use convenient.

The utility model is not limited to above-mentioned embodiment, and those skilled in the art also can make multiple change accordingly, but to be anyly equal to the utility model or similar change all should be encompassed in the scope of the utility model claim.

Finally, it should be emphasized that, the improvements of the utility model relative to prior art are understood more easily in order to allow those of ordinary skill in the art, descriptions more of the present utility model are simplified, and for the sake of clarity, present specification is omitted some other elements, and those of ordinary skill in the art it is to be appreciated that these abridged elements also can form content of the present utility model.
