High Power Infrared LED Diode: An Industry Overview

Introduction

High Power Infrared LED Diodes (HP-IRLEDs) have become an essential component in various industries, from consumer electronics to automotive and industrial applications. These diodes are designed to emit intense infrared light, which is widely used for communication, sensing, and illumination purposes. This article provides an in-depth overview of the high power infrared LED diode industry, covering its history, technology, applications, market trends, and future prospects.

History of High Power Infrared LED Diodes

The development of high power infrared LED diodes can be traced back to the early 1980s when gallium arsenide (GaAs) and gallium nitride (GaN) became popular materials for LED fabrication. Initially, these diodes were used in low-power applications, such as remote controls and barcode scanners. However, with advancements in material science and semiconductor technology, the high power infrared LED diode industry has witnessed significant growth over the past few decades.

Technology and Materials

High power infrared LED diodes are primarily made from gallium arsenide (GaAs) and gallium nitride (GaN) materials. These materials are chosen for their ability to emit infrared light efficiently and with high brightness. The manufacturing process involves epitaxial growth, where a thin layer of the chosen material is deposited on a substrate. This layer is then patterned and mounted on a semiconductor wafer. The key technology in high power infrared LED diode fabrication is the use of a multi-quantum well (MQW) structure. This structure consists of multiple quantum wells sandwiched between barriers, which allows for the efficient confinement of charge carriers and the emission of infrared light. Additionally, the use of antireflective coatings and high-quality substrates has further improved the performance of these diodes.
