Mini IR LED, or Miniature Infrared Light Emitting Diode, has emerged as a crucial component in the field of optoelectronics, particularly in applications requiring compact, efficient, and reliable infrared illumination. This article delves into the industry of mini IR LED, exploring its technology, applications, market trends, and future prospects.

Introduction to Mini IR LED Technology

Mini IR LED technology is a subset of the broader LED (Light Emitting Diode) category, specifically designed to emit infrared light. Unlike visible light LEDs, which emit light in the visible spectrum, mini IR LEDs emit light in the infrared spectrum, which is not visible to the human eye. These LEDs are compact, with dimensions often measured in millimeters, making them ideal for space-constrained applications.

Mini IR LEDs are typically made using gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) semiconductor materials. The process involves creating a p-n junction within the semiconductor, which allows for the injection of electrons and holes, resulting in the emission of infrared light when they recombine.
