Description

Acoustooptic control economizer switch

The utility model relates to a kind of control device of handling incandescent source, a kind of light switch, especially a kind of acoustooptic controlled delay battery-conserving switch.

At present, the night light of public places such as dormitory corridor, hospital, corridor, hotel all is to use the switch that needs the people to operate basically, because therefore the dark inconvenient operation of light at night all is kept burning day and night generally.So both waste electric energy, influenced the useful life of bulb again.For saves energy, a kind of touch time-delay power down switch once appearred on the market, promptly touches, delay time tens seconds or extinguish automatically after the kind somewhat.But this switch still needs the people to operate, and it is very not convenient that the user still feels.Patent Office of the People's Republic of China disclosed the utility model patent of " a kind of automatic power switch " (publication number 2093498U) on January 15th, 1992, and the disclosed technical scheme of this patent is too complicated, the cost height, and the general user is forbidding.Patent Office of the People's Republic of China disclosed a kind of utility model patent of acousto-optic control automatic time delay lamp switch again on July 15th, 1992, the technical scheme of this utility model patent is simple, cost is also accepted by the general user, but the technical scheme of this utility model has been used three lead-in wires, i.e. two power lines, a control line that links with electric light, so it can not directly replace existing switch, need special the installation, special wiring.Especially it is very inconvenient that installation is made in old housing reform, except with the concealed wire that cloth is good, also will set up an open-wire line, both bothered, and influences attractive in appearance again.

In view of the above-mentioned deficiency of existing in prior technology, the purpose of this utility model provides the acousto-optic control light switch that a kind of single line advances, single line goes out, it can with various light switch compatibilities, directly replace.

To achieve these goals, after comprising ac input end and electric light is connected, technical solution of the present utility model is connected in parallel on the full-wave rectifier in the current supply circuit, be connected in parallel on the thyristor main switch of full-wave rectifier dc output end, flow restricter in the electric power loop that it is characterized in that also comprising the photoacoustic dual-controlled circuit of control thyristor main switch and being connected on the photoacoustic dual-controlled circuit, described photoacoustic dual-controlled circuit is by the acoustic-electric change-over circuit of parallel connection, amplifier, shaping circuit, photoelectric switching circuit, compare amplifying circuit, AND circuit, thyristor switch, voltage stabilizing circuit and time-delay control electricity constitute; Wherein, the output of acoustic-electric change-over circuit, amplifier, shaping circuit with link with an input of AND circuit again after input is connected successively; The output of photoelectric switching circuit links with the positive input that compares amplifying circuit, and relatively the output of amplifying circuit and another input of AND circuit link; The control utmost point of the output of AND circuit and thyristor switch links; The control utmost point of the output of delay control circuit and thyristor main switch links.

Because all circuit are connected with electric light in the utility model, so electric light plays a kind of current-limiting protection effect to all electronic components.In addition, the utility model utilizes silicon controlled dimension properties of flow that filter capacitor is stored up in the voltage stabilizing circuit electric energy is drained and controls delay control circuit output triggering signal, the conducting of control thyristor main switch.Therefore the switch motion of thyristor main switch is clear-cut, can not go out jitter phenomenon.This practicality, also has and can directly replace the ordinary lamps switch except above-mentioned advantage than prior art, need not rewiring, the advantage of being convenient to install.

Below in conjunction with accompanying drawing and a preferred embodiment the utility model is explained in further detail:

Embodiment

With reference to Fig. 2, amplifier described in the utility model, shaping circuit, comparison amplifying circuit, AND circuit are finished by a sound, light-operated integrated circuit SK--522.With reference to Fig. 2, civil power passes through the direct current of the full-wave rectifier rectification output ripple of being made up of diode D4～D7, passes through current-limiting resistance R10 current limliting again, is the The whole control circuit supply after voltage stabilizing didoe D2 voltage stabilizing, capacitor C 3 filtering.At this moment, if ambient light is brighter, photodiode D1 conducting, the current potential of integrated circuit SK--522 5 pin is lower than the reference potential of 6 pin, and 2 pin are always low level, and thyristor T1 is in cut-off state; When ambient light was dark, photodiode D1 ended, and the current potential of integrated circuit SK--522 5 pin is higher than the reference potential of 6 pin, the comparison amplifying circuit output high level of its inside, and another input of AND circuit is that low level is in wait state; At this moment, in case Electret condenser microphone MIC receives sound, then be transformed into audio electrical signal immediately and deliver to 2 pin of integrated circuit SK--522, again through exporting high level after its inner amplifier amplification, the shaping circuit shaping, this moment, two inputs of AND circuit were high level, 7 pin of integrated circuit SK--522 are also exported high level, the thyristor T1 conducting that is triggered, and capacitor C 3 is discharged rapidly.Because thyristor T1 has the dimension properties of flow, so wait until that always thyristor T1 just automatically shut down when electric energy that capacitor C 3 is stored up drained; Because string has isolating diode D3 on the capacitor C 4, thus in capacitor C 3 when thyristor T1 discharges, capacitor C 4 is not discharged.When the electric energy of being store when capacitor C 3 drains soon, because do not have bias current in the biasing circuit of the triode T3 that resistance R 7 and R8 series connection constitute, triode T3 ends, capacitor C 4 is discharged over the ground through the control utmost point of resistance R 9 and thyristor T2, main switch thyristor T2 conducting, electric light L electrified light emitting.When the electric energy of being store when capacitor C 4 drained, in case the Rectified alternating current zero passage that is provided by diode D4～D7, main switch thyristor T2 automatically shut down, and electric light L outage is extinguished.When main switch thyristor T2 turn-offed, capacitor C 3 and C4 continued to repeat said process again through current-limiting resistance R10 charging.

With reference to Fig. 2, the time constant of electric light L electrified light emitting is determined by capacitor C 4 and resistance R 9, suitably adjusts the capacity of capacitor C 4 or the resistance of resistance R 9, can change the time length of electric light L electrified light emitting.

With reference to Fig. 3 or Fig. 4, with the whole cloth of electronic component shown among Fig. 2 to circuit board (3), in the casing that threading is made up of panel (1) and bonnet (2), and light-receiving hole (5) the harmony receiver hole (4) that photodiode D1 and Electret condenser microphone MIC are aimed at respectively on the panel (1) promptly can be made into sound described in the utility model, light-operated battery-conserving switch.
