Specify below that the utility model is described makes time-delay lighting switch related correlation technique content in manufacturing process with key switch.
The utility model content
Goal of the invention: the utility model and existing on the market delay switch relatively have characteristics such as the delay circuit structure is simple and direct, the components and parts consumption is few, circuit performance reliable, the making development cost is low, easy to use.
Beneficial effect: the utility model is described to be made the time-delay lighting switch with key switch to have a volume little; Can design and be integrated among the 86 type electrical standard panels; Be applicable to the various incandescent lightings time-delay control of house or public place, this time-delay lighting switch has tangible power savings.
Technical scheme: make the time-delay lighting switch with key switch, form by 220V alternating current, full bridge rectifier, one-way SCR circuits for triggering, delay circuit and incandescent lamp HL.
The composition of circuit and the annexation between the element
1. make the time-delay lighting switch with key switch, form by 220V alternating current, full bridge rectifier, one-way SCR TS and circuits for triggering thereof, delay circuit and incandescent lamp HL.
2. full bridge rectifier: be connected into full bridge rectifier by 4 silicon rectifier diode D1~D4; One end of the alternating current of full bridge rectifier input meets the live wire end L of 220V alternating current, the zero line side N of another termination 220V alternating current of full bridge rectifier alternating current input through incandescent lamp HL.
3. the positive pole of the dc output end of full bridge rectifier joins with an end of resistance R 1, the positive pole of electrochemical capacitor C1, the anode of one-way SCR TS respectively, and the dc output end negative pole order of bridge rectifier is to the negative electrode of controllable silicon TS.
4. one-way SCR TS and circuits for triggering thereof are made up of resistance R 1, key switch AN, electrochemical capacitor C1, resistance R 2 and silicon rectifier diode D5; The end of one termination key switch AN of resistance R 1; The other end of key switch AN connects the negative pole of electrochemical capacitor C1, an end of resistance R 2 respectively; The positive pole of another termination silicon rectifier diode D5 of resistance R 2, the order of silicon rectifier diode D5 negative pole is to the control utmost point of controllable silicon TS.
The circuit working principle: when key switch AN was in disconnection, one-way SCR T was because control utmost point triggerless electric current, and one-way SCR TS is in not conducting, and incandescent lamp HL no current extinguishes state through being.In the time of need lighting incandescent lamp HL; As long as click key switch AN; The 220V alternating current is through the control utmost point of incandescent lamp HL, full bridge rectifier D1~D4, resistance R 1, resistance R 2, silicon rectifier diode D5 and one-way SCR TS; TS provides trigger current to one-way SCR, makes the bright incandescent lamp HL of one-way SCR TS firing point.Meanwhile, electrochemical capacitor C1 slowly discharges through step-down current-limiting resistance R2.
After unclamping key switch AN, power supply is given electrochemical capacitor C1 charging through resistance R 2, rectifier diode D5, and charging current provides trigger current to the control utmost point of one-way SCR TS, makes that one-way SCR TS continues to keep conducting, and incandescent lamp HL maintainings lights.Along with reducing of charging current, after after a while, one-way SCR TS loses trigger current and makes incandescent lamp HL outage and extinguish.
