Introduction to Infrared IR LED Industry
Infrared IR LED: A Brief Overview
The infrared IR LED, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. As an essential component in various applications, such as remote controls, surveillance cameras, and communication systems, the infrared IR LED industry has been experiencing rapid development over the past few years. This article aims to provide an in-depth introduction to the infrared IR LED industry, covering its history, technology, market trends, and future prospects.
History of Infrared IR LED Industry
The concept of infrared light was discovered in the early 18th century by Sir Isaac Newton. However, it was not until the 20th century that infrared technology began to develop rapidly. In 1906, Henry Joseph Round, an English physicist, discovered that a diode could emit light when an electric current passed through it. This discovery laid the foundation for the development of the infrared IR LED industry.
In the 1960s, the first infrared IR LED was developed by a Japanese company. Since then, the technology has been continuously improved, and the applications of infrared IR LED have expanded to various fields. Today, the infrared IR LED industry has become one of the most promising and rapidly growing sectors in the semiconductor industry.
Technology of Infrared IR LED
The infrared IR LED is a semiconductor device that consists of a PN junction. When an electric current passes through the PN junction, electrons and holes recombine, emitting infrared light. The key parameters of an infrared IR LED include its wavelength, luminous intensity, and forward voltage.
The wavelength of an infrared IR LED determines its color. Generally, infrared IR LEDs with a longer wavelength are less visible to the human eye. The luminous intensity refers to the brightness of the emitted light, and the forward voltage is the voltage required to make the LED emit light.
In recent years, the technology of infrared IR LED has been continuously improved. The development of high-brightness, high-efficiency, and long-life infrared IR LEDs has become the main goal of the industry. To achieve this goal, researchers have focused on optimizing the material structure, improving the epitaxial technology, and enhancing the device structure.
