Infrared remote control transmitter diode, also known as infrared LED, is an essential component in the field of remote control technology. This article aims to provide a comprehensive introduction to the industry, covering the history, working principle, types, applications, and future trends of infrared remote control transmitter diodes.

History of Infrared Remote Control Transmitter Diode

The concept of infrared remote control technology dates back to the early 20th century. However, it was not until the 1960s that infrared remote control transmitter diodes began to gain popularity. The first commercial infrared remote control system was developed by Sony in 1964, which used a series of infrared diodes to send signals to a television set. Since then, infrared remote control technology has been widely used in various electronic devices, such as televisions, air conditioners, and audio systems.

Working Principle of Infrared Remote Control Transmitter Diode

Infrared remote control transmitter diodes work based on the principle of infrared light transmission. When a button on the remote control is pressed, the diode emits a series of infrared light pulses that correspond to the specific command. These pulses are then received by the infrared sensor in the electronic device, which decodes the signal and performs the corresponding action. The working process of an infrared remote control transmitter diode can be divided into the following steps: 1. The button on the remote control is pressed, which triggers the diode to emit infrared light. 2. The infrared light is transmitted through the air to the infrared sensor in the electronic device. 3. The infrared sensor detects the infrared light and converts it into an electrical signal. 4. The electrical signal is then processed by the microcontroller in the electronic device, which decodes the signal and performs the corresponding action.

Types of Infrared Remote Control Transmitter Diodes

There are mainly two types of infrared remote control transmitter diodes: AlGaAs infrared diodes and GaAs infrared diodes. 1. AlGaAs infrared diodes: AlGaAs infrared diodes have a longer wavelength, which is between 780nm and 950nm. They are commonly used in consumer electronics, such as televisions and air conditioners. 2.
