Introduction

The infrared LED, also known as an infrared light-emitting diode, is a semiconductor device that emits infrared light when an electric current is applied. It has become an indispensable part of modern technology, widely used in various fields such as consumer electronics, medical equipment, and industrial automation. This article will provide an in-depth introduction to the infrared LED industry, covering its history, applications, technology development, market trends, and future prospects.

History of Infrared LED

The concept of infrared light was first proposed by the French physicist, René Descartes, in the 17th century. However, it was not until the 20th century that the infrared LED was born. In 1907, the German physicist, Heinrich Hertz, discovered that certain materials could emit infrared radiation when excited by an electric current. This discovery laid the foundation for the development of infrared LEDs. In the 1960s, the infrared LED began to be commercialized, and its applications were mainly focused on remote controls. Since then, the infrared LED industry has developed rapidly, with continuous technological innovation and expansion of application fields. Today, infrared LEDs have become an essential component in many electronic products.
