Abstract
The utility model relates to a multifunctional time-delay light-out switch, which is characterized in that both ends of a switch element is connected in parallel with a controllable silicon and a half-wave rectification voltage stabilizing circuit; a gate pole of the controllable silicon is connected with an RC series connection single pulse current pulse generating circuit. The utility model works through series connection in a lamp source return circuit, and the light source can be gradually went out from bright to dark after the switch is turned off, and therefore, the utility model is convenient for daily living life of people.
Description
The utility model relates to a kind of multi-functional time-delay light-off switch of electricity field.
Existing various switch as wall switch, pulling switch etc., all is with closing with putting out to the control of light source, and people are far from suitable during to dark unexpected conversion by bright at light, and this period of while has also brought some inconvenience to walking up and down.
At above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of multi-functional time-delay light-off switch, so that light source is extinguished behind cut-off switch gradually.
In order to achieve the above object, the technical solution of the utility model is to adopt a kind of multi-functional time-delay light-off switch, the two ends of switch element S are parallel with a controllable silicon Vs and a half-wave regulator rectifier circuit, are connected with RC Series Sheet pulse current circuits for triggering on the gate pole of above-mentioned controllable silicon Vs.
Described half-wave rectifier voltage circuit is composed in series by diode VD1, current-limiting resistance R1 and voltage-stabiliser tube VD3, wherein also is parallel with a filter capacitor C1 on the voltage-stabiliser tube VD3.
Described RC Series Sheet pulse current circuits for triggering are composed in series by resistance R 2 and capacitor C 2, and wherein the positive terminal of capacitor C 2 is by resistance R 3 ground connection, and negative pole end links to each other with the negative pole of a diode VD2, the plus earth of diode VD2.
Also be connected with a fluctuation voltage on the gate pole of controllable silicon VS and absorb capacitor C 3.
The two ends of switch member S also are parallel with a luminous indicating circuit that is composed in series by resistance R 4 and light-emitting diode VD4.
The utlity model has following advantage as can be seen from technique scheme: 1, the series connection RC single shot trigger that connects of controllable silicon gate pole is given trigger current pulse of gate pole immediately after switch element disconnects, make the bidirectional triode thyristor conducting, thereby make light source continue illumination, and trigger current is because the buffer action of electric capacity when reducing gradually, also deepening gradually of light-source brightness, until extinguishing, this not only can adapt to by bright gradually to dark transformation human eye, and the place of having enough time to walk about and will go, use more convenient; 2, control circuit advantages of simple, cost is not high, is suitable for producing in batches yet; 3, in parallel luminous indicating circuit is not worked when luminous in sources such as bulbs and is extinguished work when bulb on the switch element, can send the indication luminous point, is convenient to people and finds the position of the switch in the dark accurately and open light source.
The utility model is further explained and explanation below in conjunction with accompanying drawing:
Fig. 1 is circuit theory diagrams of the present utility model.
As shown in Figure 1, the utility model be in the parallel connection of the two ends of switch element S one-way SCR (also can be bidirectional triode thyristor) Vs and the half-wave rectifier voltage circuit that constitutes by diode VD1, resistance R 1 and voltage-stabiliser tube VD3 series connection, wherein, be parallel with a filter capacitor C1 on the voltage-stabiliser tube VD3.Be connected with a pulse current triggering circuit that is composed in series by resistance R 2, capacitor C 2 on the gate pole of controllable silicon Vs, the gate pole of a termination controllable silicon Vs of this series circuit, the negative pole of a termination voltage-stabiliser tube VD3.Between the positive pole of capacitor C 2 and public ground, be connected with a resistance R 3, between the negative pole of capacitor C 2 and ground, be connected with a discharge diode VD2.In addition, make controllable silicon Vs false triggering conducting, on the silicon controlled gate pole, also be connected with a fluctuation voltage and absorb capacitor C 3 for the voltage fluctuation that prevents electrical network.Also be parallel with a luminous indicating circuit that is composed in series by resistance R 4, light-emitting diode VD4 at the two ends of switch element S of the present utility model, so that seek the position of switch in the dark.
Among Fig. 1, after switch element disconnected, half-wave rectifier voltage circuit was connected to descending trigger current of gate pole of controllable silicon VS by R2, C2.Make bulb H by bright to secretly until extinguishing.
