Abstract

The surface of a switch base plate is provided with a pressing-releasing touch 'on' key which is provided with a transparent layer and is indicated by visual light and a pressing-releasing touch 'off' key which is manually controlled randomly. The touch 'on' key enables illuminating lamps to be luminous. When a delay capacitor C-[1] of a circuit board at the back of the base plate is charged, and voltage rises to the communicating valve value of a transistor, luminous illuminating lamps can be automatically switched off. During the delaying luminescence of illuminating lamps, a storage capacitor C-[2] provides the voltage of the communicating valve value of the transistor for a control circuit through the pressing-releasing touch 'off' key, which enables illuminating lamps to be switched off at any time.

Description

Energy saving switch capable of manual turning off in delay period

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 switch that needs the short time illumination to use after the production adjustment, mostly are the time-delay control of set time.As Chinese patent CN89205940.0 disclosed " simple and practical touch Auto-delay switch ", when touching NE555 time-base integrated circuit trigger end with hand, control controllable silicon its controllable silicon of conducting and illuminating lamp series loop, illuminating lamp can not be used in normal luminous power, after circuit RC constant is determined, can not arbitrarily control the adjustment fluorescent lifetime flexibly and easily; Chinese patent CN89208646.7 disclosed " delay switch " adopts bimetal leaf fixing metal regenerative block, and the bimetal leaf heating-up time is prolonged, realize delay cutting power, its lighting bulb power difference is very big to sheet metal intensification work influence, so that mechanical adjustment is cumbersome, uses inconvenience.

The purpose of this utility model is that voltage rises to the electronic control circuit that threshold values will make the luminous lighting lamp extinguish automatically when adopting the delay capacitor charging, increases the hand control function, makes the power down switch that can manually close in the luminous time delay of a kind of lighting bulb.

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, have fixing threaded hole 2, base plate 1 surface have the indication of a band hyaline layer visible light by logical putting disconnected touch " opening " key 3 and an artificial arbitrarily control putting disconnected " pass " key 4 that touches by logical, 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 of civil powers, and in addition two opposite end rectifier power sources of bridge rectifier D are exported also order to controllable silicon T ₁, control triode T ₂R ₂C ₁What form opens delay circuit, D ₅Indication C ₂Accumulator.

Control triode T ₂Colelctor electrode meets controllable silicon T ₁The control utmost point also passes through dropping resistor R ₁Connect positive source, T ₂Emitter stage connects power cathode, T ₂Base stage with and at power positive cathode R ₂C ₁The delay capacitor C of series circuit ₁The anodal connection.The cathode power supply of indication accumulator is by dropping resistor R ₃, luminous indicating diode D ₅, C ₂Storage capacitor and D ₆The parallel circuits of voltage-stabiliser tube connects power cathode.Press logical disconnected 3 two terminals of " opening " key and the delay capacitor C of touching of putting ₁Parallel connection is pressed logical two terminals putting disconnected touch " pass " key 4 and is connected respectively delay capacitor C ₁With storage capacitor C ₂Positive pole.

When electric main was connected, bridge rectifier D exported direct current, R ₂C ₁The delay capacitor C of delay circuit ₁Upper voltage rising does not reach triode T at its voltage ₂During the value of opening, T ₂Colelctor electrode give one-way SCR T ₁Family of power and influence's voltage of the control utmost point makes T ₁Conducting, the AC 220 V civil power is by bridge rectifier D, one-way SCR T ₁, lighting bulb W forms path, lighting bulb W has the luminous of initial period.Work as C ₁The voltage that delay capacitor is set up can make triode T ₂When obtaining forward bias, T ₂Conducting, T ₂Collector electrode is given one-way SCR T ₁Family of power and influence's loss of voltage, T ₁Extinguish by, lighting bulb W.Circuit is in prepares to accept to press the logical disconnected duty that touches " opening " key of putting.

The indication accumulator is not when illuminating lamp W works, to storage capacitor C ₂Charging, the luminous indicating diode D in the path ₅Send visible pilot light.The indication accumulator is set up to keep in tank voltage and is all made light-emitting diode D ₅Luminous.With storage capacitor C ₂D in parallel ₆Voltage-stabiliser tube guarantees C ₂Need not bear high pressure.Press and logical putting that disconnected to touch " opening " key 3 surfaces are layer of transparent things, luminous indicating diode D ₅The light that sends can see the people by hyaline layer to the external world, when people used at night, can see clearly and press the logical disconnected position that touches " opening " key of putting, and is convenient to press.

When the needs lighting bulb sends when light short time, hand touches presses logical disconnected " opening " key 3 that touches put, C ₁Usually the electric charge that is full of discharges by " opening " key 3, causes triode T ₂End triode T ₂Colelctor electrode give one-way SCR T ₁Family of power and influence's voltage of the control utmost point, T ₁Conducting, the AC 220 V civil power is by bridge rectifier D, one-way SCR T ₁, lighting bulb W forms path, lighting bulb W is luminous, works as R ₂C ₁C in the constant ₁Delay capacitor voltage makes T ₂Conducting T ₁When ending, lighting bulb W automatic distinguishing.R ₂C ₁Constant is more big, C ₁Voltage Establishment more slow, press and logical put disconnected " opening " key that touches and make the shinny time to automatic distinguishing of lighting bulb more long, namely select 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, when the user need close illuminating lamp,, at this moment be full of the storage capacitor C of electric charge as long as hand touches by logical touch " pass " key that breaks of putting ₂By putting disconnected " pass " key and the delay capacitor C of touching by leading to ₁Parallel connection is added in triode T ₂Base stage, make T ₂Conducting, T ₁End, lighting bulb W extinguishes.

Among the embodiment of the present utility model, R ₁=800K Ω, R ₂=2M Ω, R ₃=250K Ω, C ₁=1000 μ f, C ₂=100 μ f, D adopts 4 * 1N4007, T ₁Adopt X1001MA, T ₂Adopt 2N9014, D ₅Adopt the LED light-emitting diode, D ₆Adopt 2CW15." 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 batch production realizes easily.
