IR LED source, or Infrared Light Emitting Diode source, has become an integral part of modern technology, particularly in the fields of communication, security, and remote control. This article aims to provide a comprehensive introduction to the IR LED source industry, covering its history, technology, applications, and future prospects.

History of IR LED Source

The concept of the infrared LED dates back to the early 20th century when scientists discovered that certain materials emit infrared radiation when electrically excited. However, it was not until the 1960s that the first practical infrared LED was developed. Since then, the technology has undergone significant advancements, leading to the widespread use of IR LED sources in various applications.

Technology of IR LED Source

An IR LED source consists of a semiconductor material, typically gallium arsenide (GaAs), gallium phosphide (GaP), or indium gallium arsenide (InGaAs), which emits infrared radiation when an electric current passes through it. The key to the IR LED's operation lies in the bandgap of the semiconductor material, which determines the wavelength of the emitted light. The technology of IR LED source can be divided into two main categories: standard IR LED and high-power IR LED. Standard IR LED is commonly used in applications such as remote control, while high-power IR LED is used in more demanding applications, such as infrared communication and thermal imaging.
