Description

The infrared remote control switch on wall

Technical field belongs to the building electric apparatus class, is the switch of a kind of control room intraoral illumination, and it is a kind of switch on wall that has manual control and infrared remote control controlled function concurrently.

The present switch on wall of background technology is very big in architectural use amount, and manufacturer is a lot, but all is hand touch switch, promptly needs directly to stir switch on wall with hand and dials the action that plate is finished lighting power switch.This closing and beautiful appearance, simple in structure, technology maturation are used the extensive of ten minutes, just because of it must use the hand toggle switch, institute is not so that it also is very convenient in life.The online propaganda that also can see some remote control wall wall switch once in a while, great majority can not be realized single mode of connection, promptly also must draw power line in addition except that two original lines of switch, and are tangible inconvenient.Also have in addition and realized single wiring, the power source design cost is higher, and many factors make and can't accept for ordinary populace.

Purpose the utility model purpose of utility model provides a kind of novel switch on wall, and it not only can realize the switch on wall function by the crawl button, can also be with special-purpose this switch of Infrared remote controller remote control.It has the power source design of the specially designed low-cost and high-performance of a cover, makes its maintenance and existing switch on wall external wiring way constant, meets existing switch on wall single line wire laying mode.

Technical scheme the utility model is achieved in that and adopts bidirectional triode thyristor control switch break-make that control circuit control controllable silicon triggers.Manual mode is to use the point driving switch button, give signal of control circuit, control circuit output triggers or pick-off signal controls controllable silicon to come switching circuit, for more convenient, safe handling, increase function of infrared remote control on this basis, and two kinds of modes of operation all can independently realize the switch opening and closing movement.During remote control, the operator presses remote controller buttons, and remote controller produces a string modulated red external signal, after this novel switch on wall receives this signal, handles through internal control circuit, and control circuit triggers or turn off thyristor is realized switching circuit.Also having a very important aspect in addition is to the utlity model has the special power source design of a cover: its power capacitor is connected on the full-wave rectification bridge dc output end, the rectifier bridge ac input end is connected on single-phase silicon-controlled yin, yang the two poles of the earth of two reverse parallel connections, with two voltage stabilizing didoes, with its negative electrode and be connected in positive source, two anodes connect two single-phase silicon-controlled controls respectively and extremely go up, and single-phase silicon-controlled the two poles of the earth are connected in the civil power loop of light switch.Detect supply voltage with voltage stabilizing didoe, and control these two single-phase silicon-controlled in good time conductings respectively.When supply voltage was lower than the voltage stabilizing didoe reverse breakdown voltage, voltage stabilizing didoe oppositely ended, and did not have electric current to flow through, and did not trigger controllable silicon, not conducting of controllable silicon, and lamp current all charges to power capacitor after the full-wave rectification bridge rectification; When supply voltage reaches the voltage stabilizing didoe reverse breakdown voltage, the voltage stabilizing didoe reverse breakdown, electric current discharges through voltage stabilizing didoe, and voltage stabilizing didoe triggers single-phase silicon-controlled conducting simultaneously, and lamp current directly flows through from controllable silicon, does not charge to power capacitor.Keep supply voltage certain like this.Use such power source design to make switch series be associated in the electric light control loop and can obtain stabilized supply voltage equally, and make the external connection of switch integral body identical, keep the simplest body of wall wire laying mode with existing switch on wall.Change this novel switched need not change within the walls of installation from original switch and connect up, can directly press former mode of connection wiring, very easy.

For the utility model content is described better, respectively with Fig. 1, Fig. 2, Fig. 3, illustrate.
