Introduction

The field of infrared (IR) LED chips has seen significant advancements in recent years, playing a crucial role in various applications such as consumer electronics, automotive, and industrial automation. IR LED chips are semiconductor devices that emit infrared light when an electrical current passes through them. This article aims to provide an in-depth overview of the IR LED chip industry, covering its technology, applications, market trends, and future prospects.

Technology of IR LED Chips

IR LED chips are based on the principle of electroluminescence, where an electrical current excites electrons in a semiconductor material, causing them to recombine and emit light. The most commonly used semiconductor materials for IR LED chips are gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium arsenide (AlGaAs). These materials have different band gaps, which determine the wavelength of the emitted infrared light. The manufacturing process of IR LED chips involves several key steps, including epitaxy, lithography, etching, and bonding. Epitaxy is the process of growing a thin layer of semiconductor material on a substrate. Lithography is used to pattern the semiconductor layer into the desired shape. Etching removes unwanted material, and bonding joins the chip to a metal lead frame for electrical connection. The efficiency and performance of IR LED chips are influenced by various factors, such as the material quality, epitaxial layer structure, and device design. Recent advancements in technology have led to the development of high-efficiency, high-brightness, and wide-angle IR LED chips, which have expanded their applications in various fields.
