Background technology:

Present known photoacoustic dual-controlled delay electronic switch is a kind of acoustic control, light-operated, electronic switch of delaying time of integrating, and now has been widely used in various place.As corridor, public bath room, corridor mouth etc., himself advantage and use value have been demonstrated fully, it mainly is made up of control circuit, load, shell three parts, but it is exactly to carry out break-make control to the load of heat radiation light sources such as ordinary incandescent lamp bubble that this photoacoustic dual-controlled delay electronic switch has a fly in the ointment only, and can not carry out reliable break-make control to the load of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp.The consumer has been subjected to placing restrictions on and retraining requirement that can not be satisfying personalized in the load of selection and use Different Light like this.Wasted the energy of a large amount of preciousnesses simultaneously.

Summary of the invention:

In order to overcome existing photoacoustic dual-controlled delay electronic switch can not carry out break-make control well to the load of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp deficiency.The order ground of the utility model design is exactly to design a kind ofly can not only carry out reliable and stable break-make control to the load of thermal radiation light sources such as ordinary incandescent lamp bubble, and can carry out reliable and stable break-make to the load of glow discharge spot lamps such as fluorescent lamp, electricity-saving lamp and control.

The technical scheme that its technical problem that solves the utility model adopts is: it mainly is the circuit by common photoacoustic dual-controlled delay electronic switch, load and relay are formed, the load bulb of the 220 volts of power inputs of civil power that are serially connected with former common photoacoustic dual-controlled delay electronic switch circuit is directly received on two left and right sides fixed contacts of relay, again the coil two ends of relay are serially connected with the input of 220 volts of power supplys of civil power, and then two moving contacts of relay are directly inserted 220 volts of power supplys of civil power, when the controllable silicon in the electronic switch control circuit satisfied its turn-on condition, controllable silicon was with conducting like this.In case controllable silicon conducting, the bridge circuit of full-bridge rectification is connected, the coil of relay has electric current to flow through electromagnetic field of generation, with two moving contacts about relay and about two fixed contacts closed simultaneously, two fixed contacts get about making, thereby load is by the work of lighting, and then end by controllable silicon after the electronic switch control circuit time-delay regular hour, the bridge circuit of the full-bridge rectification of 220 volts of power inputs of civil power can't be connected, the coil of relay does not have electric current to flow through, make magnetic field diminishes, about relay two moving contacts and about two fixed contacts separate simultaneously, the load dead electricity is extinguished.If the interior controllable silicon of general purpose type energy-saving photoacoustic dual-controlled delay electronic switch circuit this moment satisfies its turn-on condition once more, the bridge circuit of full-bridge rectification is connected once more, the coil of relay has electric current to flow through electromagnetic field of generation once more, make relay about two moving contacts and two left and right sides fixed contacts closed simultaneously once more, load gets electric work and is lighted, and then pass through the interior control circuit of electronic switch after the time-delay regular hour, controllable silicon ends once more, the bridge circuit of full-bridge rectification can't be connected, the coil of relay does not have electric current to flow through, magnetic field disappears, make relay about two moving contacts and about two fixed contacts separate simultaneously, load is extinguished.So can return multiplely reliable and stable break-make control is carried out in load.This shows, the control circuit of utility model photoacoustic dual-controlled delay electronic switch be direct control relay coil electric and dead electricity, thereby make two left and right moving contacts of relay and two left and right sides fixed contacts lighting and extinguish of control load indirectly, the control circuit in load and the electronic switch is without any relation.So two fixed contacts of relay are all a bit work that can not influence the electronic switch inner control circuit of load that connects which kind of light source.This general purpose type energy-saving photoacoustic dual-controlled delay electronic switch possesses simple in structure, utility model, and good reliability, the scope of application is wide, energy-conservation, as to reduce entire circuit greatly power consumption.Thereby can improve the useful life of whole electronic switch.

Embodiment

Can not be for further setting forth common photoacoustic dual-controlled delay electronic switch to fluorescent lamp, the shortcoming that the load of glow discharge spot lamps such as electricity-saving lamp is controlled, be described further according to Fig. 1, in Fig. 1, the incandescent bulb of load (1) directly is serially connected with the input that exchanges 220 volts of power supplys again.220 volts of AC power zero lines of civil power (26) are input to the ac power input end of the bridge rectifier of being made up of rectifier diode (3), (4), (5), (6) by the tungsten filament of the incandescent bubble of load (1); 220 volts of AC power live wires of civil power (25) are then directly received the other end of the AC power input of bridge rectifier, it is had stablize 220 volts of AC power or approximate 220 volts of AC power, the input impedance that must satisfy simultaneously 220 volts of power inputs of civil power is little, input impedance is more little, the ac power input end voltage that is input to bridge rectifier is more near 220 volts of supply voltages of civil power, too big pressure drop and fluctuation can not be arranged, direct voltage after the rectification is stable more, and just its circuit working is just reliable.Select the ordinary incandescent lamp bubble of heat radiation light source the most suitable so be serially connected with the load (1) of 220 volts of power inputs of civil power, this is because the tungsten filament D.C. resistance in the incandescent lamp bulb (1) is very little, the zero line (26) of the input of 220 volts of power supplys of civil power can waltz through the ac power input end that the interior tungsten filament of incandescent bulb (1) is delivered to full-bridge rectification very much like this, pressure drop is very little, also can ignore.The live wire (25) that exchanges 220 volts of power supplys is directly inputted to another input of the AC power of full-bridge rectification.At this moment, the ac input end of full bridge rectifier obtains a more stable alternating voltage, can be near line voltage, and the direct voltage one tunnel after the full-bridge rectification is added to the anode and the negative electrode of controllable silicon (9).Its positive pole connects the anode of controllable silicon (9), and negative pole connects the negative electrode of controllable silicon (9), satisfies the controllable silicon turn-on condition.Resistance (17) step-down is then passed through on another road, 9.1v voltage stabilizing didoe (7) voltage stabilizing, electrochemical capacitor (13) filtering, obtaining a galvanic current presses to integrated package (2) and powers, whole so common photoacoustic dual-controlled delay electronic switch circuit working process is, when by day or illuminance during greater than a certain command value, photo resistance (15) is low resistance, the partial pressure value of resistance this moment (21) and photo resistance (15) is lower than the threshold voltage of not gate, 1 pin of integrated package (2) is low level, 11 pin also are low level, make the conducting of controllable silicon (9) and by can not control by sound, when controllable silicon (9) ends, by rectifier diode (3), (4), (5), (6) bridge circuit of the bridge rectifier of Zu Chenging can not be connected.So the tungsten filament of the incandescent lamp bulb (1) of load does not have electric current to flow through, incandescent lamp bulb (1) does not work.When at night or illuminance when being lower than a certain command value, photo resistance (15) is high resistant, and the partial pressure value of this moment resistance (21) and photo resistance (15) is higher than the threshold voltage that NAND gate is imported.This moment is as long as microphone (16) receives from sound on every side, as: footsteps, clap one's hands sound, cough sound etc., be about to sound and be transformed into audio signal, after amplifying, the base stage that electric capacity (12) is coupled to triode (10) is input to 2 pin of integrated package, 11 pin that make integrated package (2) are high level, be added to the control utmost point of controllable silicon (9) pin by resistance (24), trigger controllable silicon (9) conducting.The full-bridge rectification bridge circuit that be made up of rectifier diode (3) (4) (5) (6) this moment is connected.Load incandescent lamp bulb (1) has electric current to flow through, and bulb is lighted, and integrated package this moment (2) is to keep power supply by electric capacity (13), after sound disappeared, 4 pin of integrated package (2) recovered 0V, and silicon speed-sensitive switch diode (8) is partially anti-, electric capacity (14) is by discharging to resistance (19), behind the time-delay certain hour, 8 and 9 pin of integrated package (2) are 0V, and 11 pin are low level, controllable silicon (9) ends, the bridge circuit of full bridge rectifier turn-offs, and load incandescent lamp bulb (1) does not have electric current to flow through, and incandescent lamp bulb (1) extinguishes.The control of the break-make of whole electronic switch is exactly the action of finishing light-operated, acoustic control, these three kinds of functions of delaying time according to this course of work.If have sound to be picked up once more around this moment by microphone (16), can trigger controllable silicon (9) conducting once more, load incandescent lamp bulb (1) is lighted once more.If be serially connected in 220 volts of power input loads of civil power is not ordinary incandescent lamp bubble (1), but fluorescent lamp, the load of glow discharge spot lamps such as electricity-saving lamp.The brownout of rectification full-bridge ac power input end will appear being input to so, thereby cause starting difficulty, the use of the electrical equipment of periphery is disturbed in grating flicker, might cause false triggering or load not gone out or load still has phenomenons such as shimmering after extinguishing controllable silicon (9).This is because fluorescent lamp is to cause the tube wall fluorescent material luminous by mercury vapor discharge.So needing ballast annexes such as (electric ballast or Inductive ballast and starters) to help start could be luminous, if when load incandescent lamp bulb (1) is fluorescent lamp, just relatively fluorescent tube, electric ballast or Inductive ballast and starter are serially connected with together the input of 220 volts of AC power.Because various reasons such as ballast causes the power supply wave shape distortion bigger when working, and the total harmonic content and the electric current crest that have are also higher, and the distortion shape that feeds back to power input is bigger, and dc impedance is big make the entire circuit job insecurity, some unfavorable phenomenons appear.So fluorescent lamp, the load incompatibility of glow discharge spot lamps such as electricity-saving lamp is used on the circuit of common photoacoustic dual-controlled delay electronic switch.

In embodiment illustrated in fig. 2, be that the utility model is complete enforcement circuit theory diagrams, relay (27) be a coil voltage for exchange 220 volts often open double-contact relay, can be according to different loads and the different relay of service condition selection.(28) be the coil of relay (27), two moving contacts about (29), (30) relay (27) directly connect 220 volts of alternating voltages of civil power, and two fixed contacts about (31), (32) relay (27) directly connect the two ends of free load (0).The coil (28) of its repeat circuit (27) directly is serially connected with the input that exchanges 220 volts of power supplys.The zero line (26) that promptly exchanges 220 volts of power supplys is input to by rectifier diode (3) by the coil (28) of relay (27), (4), (5), (6) ac input end of the bridge rectifier of being formed, the live wire (25) of 220 volts of power supplys of civil power then directly enters the other end that bridge rectifier exchanges input, this moment, the dc output end of bridge rectifier had a stable pulsating dc voltage output, one the tunnel directly is added to the anode and the negative electrode of controllable silicon (9), another road power supply is through resistance (17) step-down, electric capacity (13) filtering, be directly inputted to 14 pin positive power source terminals of integrated package (2) after voltage stabilizing didoe (7) voltage stabilizing, the principle of electronic switching circuit control section is the same with control principle shown in Figure 1, be the load difference that control circuit is controlled, the load that common photoacoustic dual-controlled delay electronic switch shown in Figure 1 is controlled is incandescent lamp bulb (1).The load that general purpose type energy-saving photoacoustic dual-controlled delay electronic switch shown in Figure 2 is controlled is the coil (28) of relay (27), and the character of two kinds of loads all is the same basically, can both make the circuit reliably working.But the utility model shown in Figure 2 obviously is better than common photoacoustic dual-controlled delay electronic switch shown in Figure 1, this is because the load of common photoacoustic dual-controlled delay electronic switch control shown in Figure 1 is incandescent lamp bulb (1), its power is bigger, be generally tens watts, go up hectowatt, circuit power consumption is bigger, and is unfavorable to the useful life of whole electronic switch.Another reason is can only be fit to incandescent lamp bulb is carried out break-make control.In the selection of light source, be subjected to placing restrictions on.And the load that utility model shown in Figure 2 is controlled is the coil (28) of relay (27), and its power is very little, generally has only several watts of zero points, and is very little very little to the power consumption of control circuit.Improved the useful life of whole electronic switch comparatively speaking greatly.The employed free load of utility model as shown in Figure 2 (0) is on two left and right sides fixed contacts (31) of directly receiving relay (27), (32) again, so free load (0) is no matter be work and the use not at all influence of the load of which kind of light source to whole electronic switch, work that can both be stable.Below according to enforcement schematic diagram shown in Figure 2, the entire work process of the utility model electronic switch done further again tell about: the live wire (25) of 220 volts of AC power of civil power divides the two-way input, and one the tunnel is input to the left moving contact (29) of relay (27).Another road is input to an end of the interchange input of the bridge rectifier of being made up of rectifier diode (3), (4), (5), (6), the zero line of 220 volts of power supplys of civil power also divides two tunnel inputs, and the coil (28) that relay (27) are then passed through on one road another road of right moving contact (30) that is directly inputted to relay (27) is delivered to the other end of the bridge rectifier ac power input end of being made up of rectifier diode (3), (4), (5), (6).Because it is very little to be serially connected in the resistance of coil (28) of ac power input end, the voltage of the AC power that is input to bridge rectifier there are not much pressure drops, still can keep the voltage of 220 volts of civil powers basically, to the not influence of operating voltage of control circuit.220 volts of anode and negative electrodes that directly are added to controllable silicon (9) by the pulsating dc voltage of exporting behind the bridge rectifier one tunnel of civil power, wherein anode just connects, negative electrode connects negative, satisfy its required turn-on condition, another road is through resistance (17) step-down, electric capacity (13) filtering provides the power supply of burning voltage for integrated package (2) after voltage stabilizing didoe (7) voltage stabilizing.At this moment, if night or illuminance are lower than a certain command value, photo resistance (15) is high resistant, if microphone this moment (16) receives from sound on every side, is about to sound and is transformed into audio signal.Amplify the effect of back by integrated package (2) built-in function, the control utmost point that the 11 pin output high level of integrated package (2) is delivered to controllable silicon (9) through resistance (24) triggers controllable silicon (9) conducting, this moment, the bridge circuit of full-bridge rectification was connected, there is electric current to flow through on the coil (28) of relay (27), because magnetic effect of electric current, produce an electromagnetic field, make about two two moving contacts (29) of relay (27), (30) and two left and right sides fixed contacts (31) (32) closure, free load (0) is lighted, after control circuit is delayed time the regular hour, controllable silicon (9) is ended, the bridge circuit of full-bridge rectification can not be connected, and the coil (28) of relay (27) does not have electric current to flow through, and magnetic field disappears, about two moving contacts (29), (30) with about two fixed contacts (31), (32) separately, free load (0) is extinguished.The sound around if microphone this moment (16) receives once more, controllable silicon (9) meeting conducting once more, the bridge circuit of full-bridge rectification is connected once more, the coil (28) of relay (27) has electric current to flow through electromagnetic field of generation, make relay (27) about two moving contacts (29), (30) and about two fixed contacts (31), (32) closure, free load (0) is lighted, after the time-delay regular hour, controllable silicon (9) ends, the bridge circuit of full-bridge rectification can not be connected, coil (28) no current of relay (27) flows through, and magnetic field disappears, two left and right moving contacts (29) of relay (27), (30) and two left and right sides fixed contacts (31), (32) separately, free load (0) dead electricity is extinguished, so can carry out break-make control repeatedly, make free load (0) reliably working, can not influence control circuit work and the interference of electrical equipment to external world again.
