Abstract

An electricity-saving time delay switch is the lighting switch provided with the function of delaying turn-off for controlling various lamps and lanterns. The utility model controls the lighting and delaying by the circuit with the function of delaying turn-off, in which the lighting and delaying is controlled by the mechanical contact inside the switch, and the circuit is composed of elements, such as an integrated piece and a bidirectional thyristor, etc. When the switch is shut down, lamps and lanterns work; the time-delay circuit makes lamps and lanterns delaying work for seconds to minutes and then extinguish, which makes the person who turns off lights leave under the illuminated situation. The utility model is suitable for the places, such as a living room, a bedroom, the corridor of the top and bottom of a building, a hotel and a hostel, etc. The utility model has the advantages of visible saving power and low making cost.

Description

Electricity-saving time delay switch

The utility model is a kind of improved lighting switch, particularly has the lighting switch of time delayed turn-off function economize on electricity, is used to control various light fixtures.

The break-make of existing lighting switch circuit is by the mechanical contact control of switch inside.When people's Push switch key or Drawing switch line make inner mechanical contact closed circuit conducting, lighting work; Circuit interruption after mechanical contact disconnects, light fixture extinguishes immediately.Because just closing, extinguishes immediately by lamp, people's action of must feeling about in the dark, the lamp of for example turning off the room, the walking of all must feeling about in the dark that goes to bed of the lamp of perhaps turning off the bedroom, the late into the night is corridor about building, on the aisle such as hostel, hotel, people fear to feel about in the dark and are reluctant to turn off the light, cause the logical clouds of all lamps kept burning day and night, electricity wasting is very big, and the someone develops a class delay switch in recent years, lamp closes the people walks back light prodigiosin continuity illumination a period of time, bring great convenience to people, even but the also power consumption of not turning on light that this class delay switch has after loading onto also to increase in addition and connect single line; To weaken much with lamp brightness between the one-way SCR time delay in the delay circuit, have in addition be transformed into that delay time extinguishes earlier and then bright in that normal lamp is bright, form at interval, be not suitable for fluorescent lamp.And the circuit complexity, delay time long circuit more is complicated more, and cost is high more.

At the problems referred to above, the utility model provides a kind of economize on electricity delay switch, because the back time-delay illumination of turning off the light brings great convenience to people, economize on electricity, and not power consumption of delay circuit simultaneously.

The same boss (3) and the terminal screw (5) of this economize on electricity delay switch with switch panel (2) and central authorities thereof with existing regular tap, contact 1 contact 2 contacts 3 of K switch in terminal screw (5) forming circuit, its top is useful on the button (4) of each contact on-off circuit of control, go up fixing threaded hole (6) in addition at switch panel (2), feature is to be fixedly connected with circuit board (1) on boss (3), with the nut on the existing terminal screw (5) circuit board (1) is fastened on the boss (3), has on the circuit board (1) by integrated (IC), bidirectional triode thyristor (BCR), diode (D), resistance (R), the circuit that electric capacity (C) etc. constitute.This economize on electricity delay switch can be controlled each contact on-off circuit with button (4), can also be with button or other shaped element, and each contact on-off circuit of economize on electricity time-delay pulling switch then is to control with the stay spring hook.

The utility model is widely used in room, bedroom, building places such as corridor, hostel, hotel up and down, is suitable for various light fixtures, the time-delay economize on electricity, and the person of turning off the light leaves under the situation of illumination having, and is very convenient; The other consumed power of while delay circuit, time of delay, length was adjustable; Long service life, noiseless is not destroyed original construction of switch during making, and only needing increases a circuit board (1) delay circuit, and cost is low; This economize on electricity delay switch adopts integrated (IC) circuit and bidirectional triode thyristor (BCR) element free of discontinuities pulse-triggered and self-energizing technology, reliable operation.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is a circuit diagram;

Fig. 2 is a button economize on electricity delay switch structural representation.

With reference to Fig. 1, Fig. 2, on the central boss (3) of the switch panel (2) of existing common key-press switch, be connected and fixed a circuit board (1), with the nut on the existing terminal screw (5) circuit board (1) is fastened on the boss (3).Has the circuit that constitutes by integrated (IC), bidirectional triode thyristor (BCR), diode (D), resistance (R), electric capacity (C) etc. on the circuit board (1).When pressing ship shape button (4) one ends, the contact 1 of K switch, contact 2 closed circuit conductings in the circuit, bulb is bright, supplies with people's illumination; When not needing lamp, press the end in addition of ship shape button (4), the contact 2 of K switch disconnects in the circuit, contact 1, contact 3 closures, at this moment delay circuit starts work synchronously, high-frequency pulse signal triggering bidirectional triode thyristor (BCR) conducting of integrated (IC) output, continue to power to the load, simultaneously also provide integrated (IC) working power to make it self-insurance, at this moment lamp light yellow always, when arriving delay time, 4 pin of integrated (IC) reset by force, and triggering signal is interrupted, the outage of bidirectional triode thyristor (BCR) blocking-up load circuit, meanwhile cut off the power supply to integrated (IC), assurance delay time circuit later can reliably remain on off state, also can reliable turn-off even restore electricity after outside line has a power failure.Delay time length can be by changing resistance (R ₅) and electric capacity (C ₅) from tens of second to dozens of minutes, chosen in advance as required, optional 1～5 minute of general indoor and street lighting.The wiring of this economize on electricity delay switch, installation are the same with regular tap, and with screw by fixing threaded hole (6) dress on the wall, its description can be made into button, stay-supported, push button, fall all kinds such as cis.
