IR LED Diode, also known as Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. It has been widely used in various fields, such as consumer electronics, automotive, medical, and industrial applications. This article aims to provide an in-depth introduction to the IR LED diode industry, covering its history, technology, market trends, and future prospects.

History of IR LED Diode

The history of IR LED diodes can be traced back to the 1960s when the first LED was invented. However, it was not until the late 1970s that IR LED diodes began to be used in practical applications. Since then, the technology has undergone continuous innovation and development, leading to the emergence of various types of IR LED diodes with different wavelengths and specifications.

Technology of IR LED Diode

IR LED diodes are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have excellent optical and electrical properties, making them suitable for IR LED diode production. The basic structure of an IR LED diode includes a p-n junction, a package, and an encapsulation material.

The p-n junction is the core part of the IR LED diode, where the electric current generates infrared light. The package is used to protect the diode and facilitate its installation and use. The encapsulation material is responsible for ensuring the light output and heat dissipation of the IR LED diode.

According to the wavelength of the emitted light, IR LED diodes can be divided into short-wave infrared (SWIR), mid-wave infrared (MWIR), and long-wave infrared (LWIR) categories. Each category has its own characteristics and application fields.
