How to stop tv remote control from controlling led lights?

What if the TV remote control controls the lights in the living room? It may be because the lights in your living room are leds, and the light remote control or switch sends user instructions to the receiver through wave signals of different frequencies. There are many encoding formats for these instructions, which can be called “protocols”, similar to the concept of the TCP/IP protocol we use on the Internet.

What if this happens when the TV remote controls the lights in the living room? Generally speaking, the TV remote control to control the lights in the living room uses the infrared remote control receiver to receive the infrared remote control signal, which is composed of an infrared receiver, an infrared signal amplification circuit, a frequency selection circuit, and a shaping circuit. Because its frequency selection circuit is generally composed of resistive elements, the anti-interference ability of the entire remote control receiving circuit is mainly guaranteed by the demodulation circuit behind the remote control receiver. Many demodulation IC circuits are common and can be used in various infrared remote control products. , increasing the possibility of mutual interference.

If the TV remote control controls the lights in the living room, the coding of the infrared remote control demodulation circuit is relatively simple, and the carrier frequency of the remote control signal is close to the infrared signal sent by the TV remote control, which may cause the TV remote control to control the lights in the living room. When pressing some buttons of the TV remote control, the lights in the living room may be interfered and malfunctioned by infrared signals. In this case, this interference can usually be reduced by reducing the sensitivity of the receiving circuit of the living room light.

It may also be that the quality of the lighting in the living room is poor, and the coding requirements for controlling the lighting in the living room are not too high. The living room light receives the infrared signal from the TV remote control light, and the code of the living room light may be cracked. Then the TV remote control can control the lights in the living room, here are three ways for you:

1. Replace the lamps in the living room with more advanced lamps;

2. Use a black plastic bag to block the TV remote control sales signal light;

3. Wrap the lamp rectifier in the living room with black electrical glue. Remember to wrap it in a black plastic bag.

The above is all about “How to prevent TV remote control from controlling LED lights”. After reading the above answers, do you have a certain understanding of this?
