Micro IR LED, or Micro Infrared Light Emitting Diode, is a cutting-edge technology that has gained significant attention in recent years. These tiny, efficient infrared light sources are revolutionizing various industries, from consumer electronics to automotive and medical applications. This article aims to provide an in-depth introduction to the micro IR LED industry, covering its technology, applications, market trends, and future prospects.

Technology Overview

Micro IR LED technology is based on the principles of semiconductor physics. It involves the creation of tiny, high-efficiency light-emitting diodes that emit infrared light. These diodes are typically made from materials such as gallium arsenide (GaAs), aluminum gallium arsenide (AlGaAs), or indium gallium arsenide (InGaAs). The key to micro IR LED technology lies in the ability to fabricate these diodes with extremely small dimensions, often on the order of micrometers.

One of the primary advantages of micro IR LED technology is its ability to achieve high light output and efficiency in a compact form factor. This is achieved through the use of advanced epitaxial growth techniques, which allow for the precise control of the semiconductor layer structure. Additionally, micro IR LEDs can be designed to operate at different wavelengths, ranging from near-infrared (NIR) to short-wave infrared (SWIR), depending on the specific application.
