Description

A lighting remote control switch

The utility model relates to a switch, in particular to a lighting remote control switch.

The lighting switch that is generally used at present all is to control the light bulb to go out with manual operation switch button. There are also lighting remote control switches on the market to sell, but they can only control the on and off of a lamp, and a general family has several rooms, and each room has a lighting bulb, so it is very inconvenient to use.

The purpose of the utility model is to provide a lighting remote control switch capable of controlling the on and off of two or more lighting bulbs and realizing centralized control.

The technical solution for realizing the purpose of the above invention is to include a transmitter and a receiver. The transmitter is composed of a power supply, a key group, an oscillation generator, and an infrared emitting device. Multiple keys in the key group are connected to the input end of the oscillation generator in sequence, and the infrared emitting device is connected to the output end of the oscillation generator. When a key in the key group is turned on, the oscillation generator works, and the output terminal outputs a pulse of a certain frequency. The infrared emitting tube is turned on at the rising edge of the pulse and turned off at the falling edge, thus emitting a pulse with the same frequency as the pulse. infrared waves. The receiver is composed of a power supply, an infrared receiving device, an identification circuit, a conduction circuit, and a relay group corresponding to the button group. The infrared receiving device, the identification circuit, and the conduction circuit are connected in sequence. Turn on multiple outputs of the circuit. When the infrared receiving device receives the infrared wave of a certain frequency emitted by the infrared emitting device, it converts the infrared wave into an electrical signal of the same frequency, and inputs it into the identification circuit. The identification circuit identifies the frequency of the electrical signal, and outputs the corresponding frequency The terminal outputs the level, so that the corresponding conduction circuit is turned on, and the corresponding relay operates.

The utility model can remotely control the on and off of the corresponding relays in the receiver through the buttons of the transmitter, thereby remotely controlling the on and off of multiple bulbs, and realizes the centralized control of the lighting bulbs in multiple rooms in one room, which is very convenient to use, and The structure is simple and the cost is low.

Below in conjunction with accompanying drawing, the utility model is described in further detail.

The utility model is composed of a transmitter and a receiver. The transmitter is composed of a power supply, a button group 1, an oscillation generator 2, and an infrared emitting device 3. Button group 1 includes six buttons S1-S6. Oscillator 2 is composed of LC2190 chip and its peripheral circuits. Buttons S1-S6 are connected to input pins 13-8 of LC2190 in sequence. The output pin 1 of LC2190 is connected to the base of triode V7 after being connected in series with R7, the infrared emitting device 3 is connected to the collector of V7, and the emitter of V7 is grounded. After R8 and C1 are connected in parallel, one end is connected to pin 2 of LC2190, and the other end is grounded. The values of R8 and C1 determine the reference frequency output by LC2190S. When S1 is turned on, LC2190 outputs the reference frequency. When S2-S6 are respectively turned on, LC2190 outputs 2-6 multiplied frequency respectively. When R8 is 4K and C1 is 0.2μ, the output reference frequency of LC2190 is 2KHz. The receiver is composed of a power supply, an infrared receiving device 4 , an identification circuit 5 , a conduction circuit 6 , and a relay group 7 corresponding to the key group 1 . The identification circuit 4 is composed of the LC2200 chip and its peripheral circuits. The infrared receiving device 4 is connected to the input pin of the LC2200, and the output pins A-F of the LC2200 are connected to the R1-R6 of the conduction circuit 6 in sequence. R1-R6 are respectively connected to the bases of V1-V6 in sequence, the six relays J1-J6 are respectively connected to the collectors of V1-V6 in sequence, and the emitters of V1-V6 are respectively grounded. When any button in the transmitter is pressed, the oscillation generator 2 works, and its output terminal outputs pulses of a certain frequency, thereby controlling the conduction frequency of V7. The infrared emitting device 3 is turned on at the rising edge of the pulse and turned off at the falling edge, thereby emitting infrared waves with the same frequency as the pulse. For example, when S2 is turned on, LC2190 works, the output pin outputs a 4KHz pulse, and the infrared emitting device 3 emits a 4KHz infrared wave. When the infrared receiving device 4 in the receiver receives the 4KHz infrared wave emitted by the infrared emitting device 3 in the transmitter, it converts the infrared wave into a 4KHz electrical signal, and inputs it into the LC2200, and the LC2200 identifies the frequency of the electrical signal, and then The output terminal pin B corresponding to this frequency outputs the level, so that the R2 connected to B is turned on, the transistor V2 is turned on, and the corresponding relay J2 is activated.
