Revolutionizing Hidden Communication: The Power of Infrared LED Light Technology

Infrared LED light, also known as infrared diode, is a type of light emitting diode that emits infrared radiation. It has become an indispensable part of modern life, widely used in various fields such as consumer electronics, automotive, medical, and industrial applications. This article will introduce the industry of infrared LED light, covering its history, technology, applications, and market trends.

History of Infrared LED Light

The history of infrared LED light dates back to the early 20th century. In 1900, the German physicist Heinrich Hertz discovered the existence of infrared radiation. However, it was not until the 1960s that the first infrared LED was developed by Nick Holonyak Jr., an American physicist. Since then, the technology has been continuously improved and developed, leading to the widespread application of infrared LED light in various fields.

Technology of Infrared LED Light

Infrared LED light is a semiconductor device that emits infrared radiation when forward biased. The main materials used in the production of infrared LED light are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). These materials have excellent optical and electrical properties, making them suitable for infrared LED light production.

The manufacturing process of infrared LED light includes several steps:
1. Crystal growth: High-purity semiconductor materials are used to grow single crystals through the Czochralski method.
2. Crystal slicing: The single crystal is sliced into thin wafers.
3. Diffusion: The wafer is diffused with impurities to create a p-n junction.
4. Etching: The wafer is etched to form the LED structure.
5. Packaging: The LED is packaged with a lens and a heat sink to improve its performance and lifespan.
