Infrared IR LED: A Brief Overview

Infrared IR LED, or infrared light-emitting diode, is a type of semiconductor device that emits infrared light when an electric current is applied. As a key component in various applications, such as remote controls, surveillance systems, and medical devices, the infrared IR LED has become an indispensable part of our daily lives. This article will provide an in-depth introduction to the infrared IR LED industry, covering its history, technology, applications, and market trends.

History of Infrared IR LED

The concept of infrared light was first proposed by the English physicist, Willoughby Smith, in 1666. However, it was not until the late 19th century that the first infrared LED was invented. In 1907, the German physicist, Heinrich Hertz, discovered that certain materials could emit infrared radiation when subjected to an electric field. This discovery laid the foundation for the development of infrared IR LED technology. In the 1960s, the infrared IR LED industry began to take shape. At that time, the main application of infrared IR LED was in military and aerospace fields. With the continuous development of technology, the application of infrared IR LED has been expanding to various fields, such as consumer electronics, medical equipment, and automotive industry.

Technology of Infrared IR LED

The infrared IR LED is a semiconductor device that emits infrared light. It consists of a p-n junction, which is formed by the diffusion of p-type and n-type semiconductor materials. When an electric current is applied to the p-n junction, electrons and holes are recombined, releasing energy in the form of infrared light. The main parameters of an infrared IR LED include wavelength, luminous intensity, forward voltage, and forward current. The wavelength of infrared IR LED is typically between 780nm and 3000nm. The luminous intensity refers to the amount of light emitted by the LED, which is measured in milliwatts (mW). The forward voltage and forward current are the voltage and current required to make the LED emit light. The production process of an infrared IR LED includes the following steps: material preparation, epitaxy, slicing, and packaging. The quality of the infrared IR LED is closely related to the epitaxy process, which determines the performance of the LED.
