Abstract

The utility model discloses a double-wire remote switch, which pertains to the field of electrician tool. The transformer primary coil of the said utility model is connected in series with illuminating lights via circuit close/open contact points in the infrared receiver; the secondary coil thereof is connected to the DC control circuit in the infrared receiver via electric bridge. After parallel connection, one terminal of the capacitor and resistor is connected to a terminal of the transformer, the other is connected to one output terminal of another electric bridge, the output terminal of the electric bridge is connected to the DC control circuit in the infrared receiver. The other output terminal of the electric bridge is connected to illuminating lights. The remote switch avoids the bother of replacing battery and improves working reliability and practicality. At the same time, double-wire remote switch can quite easily replace manual switch.

Description

Two line remote control switches

One, technical field

The utility model belongs to electrician's field of components, relate to a kind of can remote-controlled lighting switch.

Two, background technology

Lighting switch in the building all is manual, and people grope very inconvenience of switch in the dark before electric light is opened, even familiar environment also will guard against the underfooting to mix foreign material, step on sky or collision.Remote control switch is existing the application on household electrical appliance, by the break-make of remote controller control circuit.The remote control switch product that a kind of may command circuit is arranged on the market, its inner installation number joint dry cell that needs is to realize the control action of DC control circuit in the infrared receiver.This structure is brought the trouble of changing battery, just in case ignore the replacing battery, will cause remote control to lose efficacy.Simultaneously, the turnover lead of existing remote control switch product has four lines, and two advance two goes out, and the switch installation place of existing building has only two lines, and one-in-and-one-out makes remote control switch be difficult to replace hand switch.

Three, summary of the invention

The purpose of this utility model provides a kind of two line remote control switches.Two lead one-in-and-one-outs make it to replace hand switch and become simple and easy to do.The input that this two line remote control switches are achieved in that transformer opens and closes the contact by the circuit in the infrared receiver and connects with illuminating lamp, and electric bridge that output is connected into by diode and the DC control circuit in the infrared receiver link.An input of an end and transformer joins after capacitor and the resistance parallel connection, and an input of the other end and electric bridge links, and the DC control circuit in the output of electric bridge and the infrared receiver connects.Another input of electric bridge connects with illuminating lamp.

This two line remote control switches can be replaced hand switch with comparalive ease, have avoided changing the trouble of battery, have improved functional reliability, therefore are more convenient for promoting the use of.

Four, description of drawings

Fig. 1 is the electrical block diagram of two line remote control switches.

Five, embodiment

Two line remote control switches adopt remote controller of the prior art and infrared receiver.Set up transformer 6, the input of transformer opens and closes the contact by the circuit in the infrared receiver 5 and connects with illuminating lamp.Because number of primary turns is many, enamelled wire is thinner, and in order to prevent easy heating burnout under the series connection, the utility model two line remote control switches change and are thicker enamelled wire, to reduce resistance.The electric bridge 4 that the output of transformer then is connected into by diode and infrared receiver connect with interior DC control circuit.220 volts of transformer 6 input terminal voltages, 9 volts of output end voltages.When in the receiver during closing of contact electric light bright, transformer has electric current, can export secondary voltage.Be the power supply of infrared receiver DC control circuit, infrared receiver receives that the power-off signal of remote controller can make the contact open, current cut-off, and electric light extinguishes.At this moment transformer is not just exported secondary voltage yet.In order to guarantee the operate as normal of remote control switch, electric capacity 1, resistance 2 and electric bridge 3 have been set up in the circuit, electric capacity 1 joins with resistance 2 back one ends in parallel and input of transformer, an input of the other end and electric bridge 3 links, DC control circuit links in the output of electric bridge 3 and the receiver 5, and another input of electric bridge 3 connects with illuminating lamp.So, the DC control circuit of receiver 5 can be by two kinds of approach with 9 volts of power voltage supplies.The one, when opening, passes through by illuminating lamp transformer-supplied.The 2nd, when extinguishing, illuminating lamp powers by electric capacity and resistance.Its operation principle is: when illuminating lamp is in when extinguishing, its filament still has the energising function, and electric capacity 1, resistance 2, electric bridge 3 in this moment circuit have been formed path between the illuminating lamp.220 volts of the voltages of former AC power become 9 volts by electric capacity 1 and resistance 2 step-downs, and electric bridge 3 makes to exchange and becomes direct current, are receiver 5 power supplies.At this moment lighting filament is only switched on not luminously, and this is because the resistance of circuit is big, and the electric current by illuminating lamp reduces that therefore lamp is not luminous.But receiver 5 can receive the infrared signal of remote controller and closed circuit makes illuminating lamp luminous.Opening under the lamp state, the circuit in illuminating lamp, the receiver opens and closes the contact and the transformer input constitutes path, and the transformer output sends 9 volts alternating current.Becoming direct current through electric bridge 4 again is the receiver power supply.Electric bridge 3 and electric bridge 4 as figure connect, and can avoid sending separately electric current and cause interference.In practice, lighting is varied, incandescent lamp is a filament conducting electric current, fluorescent lamp is a gas conduction in the fluorescent tube, their resistance value difference can change the voltage in the remote control switching circuit, so electric capacity 1 and resistance 2 can adopt adjustable, different lamps there are different gears, the extensive applicability energy can be arranged.
