History of IR LED for Remote Control

The concept of IR LED for remote control was first proposed in the 1970s. At that time, the main technology for remote control was infrared light. The first IR LED remote control was developed by RCA, an American company. In the 1980s, IR LED remote controls began to be widely used in the market, and have become an essential part of consumer electronics products.

Working Principle of IR LED for Remote Control

The working principle of IR LED for remote control is based on the principle of infrared light transmission. When the user presses a button on the remote control, the IR LED emits an infrared light signal. The receiver on the electronic product receives the infrared light signal and converts it into an electrical signal, which is then processed by the microcontroller to achieve the corresponding control function.
