Abstract
The utility model discloses a timing electric-economizing switch for corridor lights, used in the public places such as the corridors (passageways, stairways) of the residential houses and the buildings. When in use, only one press on the push button can realize the auto extinguishing of the light after lighting for a short time. The timing time of the utility model can be arbitrarily arranged from 1 second to 33 minutes according to the requirements of the users. The utility model matched with a conventional normal open button switch can realize the control of two or more places.
Description
The utility model relates to a kind of luminous lamp switch, particularly a kind of timing economize on electricity corridor switch (being called for short economize on electricity corridor switch).
Before the utility model is made, the illuminating lamp in the corridor of residential houses and building places such as (corridor, staircases), its control switch all adopts the switch or the ganged switch of " switching " formula.The deficiencies in the prior art are that the former uses inconvenience, wiring more complicated when the latter presses dress.Need the stair upper/lower terminal respectively once when using simultaneously by switch.Because some bad habits use corridor lamp in time not close, and make corridor lamp become altar lamp, have so both wasted electric energy, make bulb be easy to damage again.Therefore corridor lamp performs practically no function in a lot of residential houses, falls frequently and causes injured accident.
The purpose of this utility model provides a kind of improved switch, and it can overcome the deficiencies in the prior art.
Main points of the present utility model are that it except a normally open push button switch is arranged, also has an electronic circuit that comprises timing circuit and delay circuit etc.As long as press button No. one time when this switch uses, illuminating lamp is open-minded immediately, and (for example 30 seconds) are then closed voluntarily behind certain hour.Circuit is obstructed when closing at ordinary times, not loss electric energy.
Below in conjunction with accompanying drawing the utility model is described.
Accompanying drawing is an electrical schematic diagram of the present utility model.
The utility model is made up of normally open push button switch K and timing, time-delay triggering, protection and rectification circuit.D
1~D
4Form bridge rectifier, timing circuit is by resistance R
1, R
2And capacitor C
1, C
2Form, be connected between the control utmost point and negative electrode of thyristor SCR resistance R
1With capacitor C
2Double as Power Capacity fraction delay trigger circuit.
When pressing the button K switch, alternating current is through load (as bulb), bridge rectifier, diode D
5To capacitor C
1Carry out the transient high-current charging.Resistance R
1And capacitor C
2Make thyristor SCR time-delay triggering and conducting, capacitor C during the thyristor conducting
1Last charging voltage reaches more than 200 volts.
Button K discharges the back timing circuit makes thyristor SCR continue just to turn-off after conducting a period of time.
Timing is mainly by resistance R
1, R
2, capacitor C
1Parameter decision, the parameter that changes said elements can be adjusted timing.
Capacitor C
3And resistance R
3The GPF (General Protection False circuit of forming thyristor.
Be serially connected with button switch K and capacitor C
1Between diode D
5Effect be: prevent that 1, thyristor SCR is because of capacitor C
1And form the loop between it and produce vibration and damage; 2, prevent capacitor C
1On voltage after thyristor SCR conducting, be reduced to the tube voltage drop of thyristor rapidly, thereby guarantee realization regularly.3, during thyristor SCR conducting, with the electronegative potential and the capacitor C of thyristor anode
1High potential isolate.
Owing to adopted capacitor C
2With isolating diode D
5Make the utility model realize two places or how to control electrical appliance with plain mode.
If implement two places control, then draw two leads from the two ends of button switch K by dress the utility model switch , And, and locate by adorning a common normally open push button switch at another at a place with the utility model.Two push-button switch parallel connections, then can realize control illuminating lamp in two places with two leads, play the effect of ganged switch.It is compared with traditional ganged switch except that economize on electricity, also has easy-to-connect and saves advantages such as lead.
Use the same method and also can realize how controlling, promptly the utility model switch is set, all often open common push-button switch by adorning one in remaining various places at a place.
In the utility model, R
1Value 500K Ω-3M Ω, R
2Value
100K Ω-1M Ω, C
1Value 1 μ f-220 μ f, C
2Value 0.1 μ f-100 μ f, then timing range can be adjusted at 1 second~33 minutes, can set arbitrarily according to customer requirements.Usually be set in 15~60 seconds for the corridor switch and be advisable.
The utility model also can be used as timer and is used for controlling multiple electric equipment except can be used as timing electric-economizing switch for corridor light.
The utility model is simple in structure, and is safe and reliable, easy to use by filling, and can rationally use passageway lighting lamp, saves energy. Can realize two places or how to control.
Claims (2)
1, a kind of timing economize on electricity corridor switch with normally open push button switch.It is characterized in that it also comprises by diode D
