Abstract

The output terminal of an eliminator power is connected in parallel with an indicator circuit formed by the series connection of a dropping resistor R3 and a light-emitting diode D5. Switching on and disconnecting the two terminals of a touch 'off' key 4 respectively to connect in parallel with a delay resistor R2 so that the 'off' key is switched on to directly control the charging of a delay capacitor C during the delay time of switching on a lighting bulb W. Disconnecting the 'off' key can immediately control the switching off of the lamp so that the purpose of randomly controlling the switching on and switching off during the delay time is achieved.

Description

Energy-saving switch capable for open and close in time delay

The utility model belongs to the power down switch that is used to handle incandescent source in the electricity.

Corridor, corridor, toilet and other power down switchs that needs the short time illumination to use after the production adjustment, mostly are the time-delay control of set time.Chinese patent CN90226586,5 disclosed " power down switchs that can manually close in the time delay " are because storage capacitor reserve power promptly, at energized first, the back incoming call that has a power failure, switch continuously in the short time, all can not realize turning off the light, cause the waste of electric power, also cause and use inconvenience.

The purpose of this utility model is to adopt the method that the delay circuit storage capacitor is is directly discharged and recharged, and makes can manually arbitrarily control in a kind of time delay to close the power down switch of opening.

The positive structure of the utility model as shown in Figure 1.

Circuit theory of the present utility model as shown in Figure 2.

The both sides of switch baseplate 1, there are fixing threaded hole 2, base plate 1 surface to have one disconnectedly to touch that pressing of " opening " key 3 and an artificial arbitrarily control is logical putting disconnected " pass " key 4 that touches with logical the putting of pressing of hyaline layer visible light indication, base plate 1 back side, there is a control illuminating lamp " to open " time-delay, the artificial arbitrarily circuit board 5 of " pass ".

Lighting bulb W connects with two diagonal angle ends of bridge rectifier D and inserts 220 volts civil powers, and two the opposite end rectifier power sources output in addition of bridge rectifier D and order are to the indicating circuit that delay circuit, R3D5 are composed in series of opening of controllable silicon T1, control triode T2R2C composition.

Control triode T2 collector electrode connects the controllable silicon T1 control utmost point and connects positive source by dropping resistor R1, and the T2 emitter connects power cathode, the T2 base stage with and be connected at the delay capacitor C of power positive cathode R2C series circuit positive pole.The cathode power supply of indicating circuit connects power cathode by dropping resistor R3, luminous indicating diode D5.Putting by logical that disconnected to touch 3 two terminals of " opening " key in parallel with delay capacitor C, in parallel with time delay resistance R2 respectively by logical two terminals putting disconnected touch " pass " key 4.

When electric main is connected, bridge rectifier D exports direct current, the delay capacitor C of R2C delay circuit goes up voltage and slowly rises, when its voltage does not reach the triode T2 value of opening, the collector electrode of T2 gives the one-way SCR T1 control utmost point family of power and influence's voltage, make the T1 conducting, exchange 220 volts of civil powers and form path by bridge rectifier D, one-way SCR T1, lighting bulb W, lighting bulb W has the luminous of initial period.When the voltage of setting up when the C delay capacitor can make triode T2 obtain forward bias, the T2 conducting, the family of power and influence's loss of voltage, T1 that the T2 collector electrode is given one-way SCR T1 extinguishes by, lighting bulb W.Circuit is in to be prepared to accept to put the disconnected operating state that touches " opening " key by leading to.

When illuminating lamp W does not work, send visible pilot light for luminous indicating diode D5 after 3 step-downs of positive source process resistance R.Putting by logical that disconnected to touch " opening " key 3 surfaces are layer of transparent things, the light that luminous indicating diode D5 sends can see the people by hyaline layer to the external world, when people used at night, can see clearly by putting the disconnected position that touches " opening " key all, is convenient to press.

When the needs lighting bulb sends when light short time, hand touches by logical touch " opening " key 3 that breaks of putting, the electric charge that C is full of usually discharges by " opening " key 3, cause triode T2 to end, the collector electrode of triode T2 gives the one-way SCR T1 control utmost point family of power and influence's voltage, the T1 conducting, exchange 220 volts of civil powers and form path by bridge rectifier D, one-way SCR T1, lighting bulb W, lighting bulb W is luminous, when C delay capacitor voltage in the R2C constant ended T2 conducting T1, lighting bulb extinguished automatically.The R2C constant is big more, and the voltage of C is set up slow more, makes lighting bulb shinny long more to the time of extinguishing automatically by logical touch " opening " key that breaks of putting, and promptly selects RC capacitance-resistance value difference, can obtain the different fluorescent lifetime of lighting bulb.

In the luminous any time of lighting bulb W time-delay, need close illuminating lamp, then touch by logical touch " pass " key that breaks of putting with hand, at this moment the DC power supply both positive and negative polarity after the rectification and meet delay capacitor C, make C moment quick charge, triode T2 conducting, T1 ends, and lighting bulb W keeps luminous by " passs " key path and T2be knot moment, when hand is decontroled by logical when putting disconnected touch " pass " key, at this moment, moment conduction path cut-out, and triode T2 is in conducting, and T1 is ended, lighting bulb W extinguishes, and has realized appointing in the time-delay fluorescent lifetime time may command to turn off the light.In the time that lighting bulb W turns off the light, press " opening " key, then may command is turned on light.

In the example of the present utility model, R1=820K Ω, R2=2M Ω, R3=200K Ω, C=1000Mf, D adopts 4 * 1N4007, T1 employing * 1001MA, and T2 adopts 2N9014, D5 adopts the LED light-emitting diode, " open " key 3 and " pass " key 4 and adopt by the logical automatically reset sensitive switch that breaks of putting, it is very short that it presses distance, makes the switch surface can do smooth attractive and durablely.

The utility model is simple in structure, and is easy to operate, adopts general element just can assemble, and must special instrument debugging not detect, and produces in batches easily and realizes.
