Introduction

The IR LED diode, short for Infrared Light Emitting Diode, has become an integral part of various industries due to its numerous applications. This article aims to provide an in-depth introduction to the IR LED diode industry, covering its history, working principles, applications, market trends, and future prospects.

History of IR LED Diode

The concept of an IR LED diode dates back to the early 20th century when the first light-emitting diodes (LEDs) were invented. However, it was not until the 1960s that IR LEDs were developed, primarily due to advancements in semiconductor technology. Initially, IR LEDs were used in limited applications, such as remote controls and barcode scanners. Over the years, the demand for IR LED diodes has increased significantly, leading to the growth of the industry.

Working Principles of IR LED Diode

An IR LED diode is a semiconductor device that emits infrared light when an electric current is applied. It consists of a P-type semiconductor and an N-type semiconductor, which are joined together to form a PN junction. When an electric current flows through the PN junction, electrons and holes recombine, releasing energy in the form of photons. These photons have a wavelength longer than visible light, making them infrared. The working principle of an IR LED diode can be summarized as follows: 1. An electric current is applied to the PN junction. 2. Electrons and holes recombine at the junction, releasing energy in the form of photons. 3. The emitted photons have a wavelength longer than visible light, making them infrared.
