Description

Single the illumination time-delay that push-button switch is made

Technical field

The utility model belongs to electronic technology and power-saving technique field, is the illumination time-delay of making about a kind of single push-button switch.

Background technology

Integrated package was connected into the monostable time delay circuit when common illumination delay circuit adopted 555 bases more, drove relay adhesive or release then, and then the bright incandescent lamp in control point; What also have is overlapped to form delay circuit with discrete component, lights incandescent lamp through control one-way SCR or bidirectional triode thyristor.

Many, the circuit more complicated of components and parts that various finished product ubiquities use on the market, and then be accompanied by the more high fact of fault rate, also there are defectives such as cost of manufacture height.

To have the deficiency of finished product on the market now and have many defectives in order to overcome, be necessary to study a kind of simple and direct delay circuit, few, the reliable production program of circuit working of components and parts consumption.

Below the correlation technique that in implementation process, relates to of the illumination time-delay in detail single push-button switch made do further to describe.

The utility model content

Goal of the invention: compare with existing delay switch circuit on the market, have characteristics such as the delay circuit structure is simple and direct, use components and parts consumption is few, circuit performance reliable, the exploitation and composition cost is low, easy to use.

Beneficial effect: it is little that the described illumination time-delay of the utility model has a volume; Can design and be integrated in the 86 type electrical standard magazines; Be applicable to the various incandescent lightings time-delay controls of house or public place; Illumination time-delay has tangible power savings, popularizes, promoted the use of big meaning.

Technical scheme: single the illumination time-delay that push-button switch is made, form by civil power alternating current AC, bridge rectifier, one-way SCR triggering and delay control circuit, incandescent lamp HL, it is characterized in that:

The live wire end L serial connection incandescent lamp HL of civil power alternating current AC connects an end of the alternating current input of bridge rectifier element QZ, and the zero line side N of civil power alternating current AC connects the other end of the alternating current input of bridge rectifier element QZ;

The positive pole of the bridge rectifier element QZ dc output end in the bridge rectifier and an end of resistance R 1, the positive pole of electrochemical capacitor C1, the anode of one-way SCR VS join, and the negative pole order of bridge rectifier element QZ dc output end is to the negative electrode of controllable silicon VS;

One-way SCR triggers and delay control circuit: be made up of resistance R 1, push-button switch AN, electrochemical capacitor C1, step-down current-limiting resistance R2, silicon rectifier diode D1; The anode of one termination one-way SCR VS of resistance R 1; The end of another termination push-button switch AN of resistance R 1; The negative pole of another termination electrochemical capacitor C1 of push-button switch AN, the end of step-down current-limiting resistance R2; The positive pole of another termination silicon rectifier diode D1 of step-down current-limiting resistance R2, the negative pole order of silicon rectifier diode D1 is to the control utmost point of controllable silicon VS.

The circuit working principle: the circuit of the illumination time-delay of single push-button switch making is when push-button switch AN is in disconnection, and one-way SCR VS is because control utmost point triggerless electric current, and one-way SCR VS is in not conducting, and incandescent lamp HL no current extinguishes state through being.When needs incandescent lamp HL lights; As long as click push-button switch AN; Civil power alternating current AC is through the control utmost point of incandescent lamp HL, bridge rectifier, resistance R 1, resistance R 2, silicon rectifier diode D1 and one-way SCR VS; VS provides trigger current to one-way SCR, makes the bright incandescent lamp HL of one-way SCR VS firing point.Meanwhile, electrochemical capacitor C1 discharges up to discharge off through resistance R 2.

Behind release button switch AN, electrochemical capacitor C1 provides trigger current through step-down current-limiting resistance R2, silicon rectifier diode D1 to the control utmost point of one-way SCR VS, makes that one-way SCR VS continues to keep conducting, and incandescent lamp HL maintainings lights; Along with reducing of electrochemical capacitor C1 discharging current, after after a while, one-way SCR VS loses trigger current and makes incandescent lamp HL outage and extinguish.

Description of drawings

Accompanying drawing 1 is the circuit working schematic diagram of the illumination time-delay of single push-button switch making; The QZ of bridge rectifier is a rectification silicon stack in the accompanying drawing 1.

Embodiment

Below accompanying drawing 1 and description of drawings are to specifications done further to describe to the utility model correlation technique in conjunction with following examples.

The parameter of components and parts and selection

QZ is the silicon rectifier silicon stack in the circuit, and also can select 4 models for use is 1N4007, and parameter is the silicon rectifier diode of 1A/1000V;

It is the one-way SCR of BTA plastic packaging that VS selects packing forms for use, and parameter is 1A/400V;

It is that 1W, its resistance are 1K Ω that resistance R 1 is selected RJ type, power for use; It is that 0.5W, its resistance are 16K Ω that step-down current-limiting resistance R2 selects RJ type, power for use;
