Mini IR LED, or Miniature Infrared Light Emitting Diode, has emerged as a key technology in the field of infrared lighting and sensing. These compact and efficient devices are finding applications in a wide range of industries, from consumer electronics to automotive and industrial automation. This article provides an in-depth introduction to the mini IR LED industry, covering its technology, applications, market trends, and future prospects.

Introduction to Mini IR LED Technology

Mini IR LED technology is based on the principles of semiconductor physics, where an electric current excites electrons within a semiconductor material, causing it to emit infrared light. The term "mini" refers to the small size of these LEDs, which are typically less than 5mm in diameter. This compact size allows for integration into various devices without compromising on performance.

Mini IR LEDs are constructed using a p-n junction, where the p-type and n-type semiconductor materials are combined. When an electric current is applied, electrons from the n-type material are pushed into the p-type material, recombining with holes and releasing energy in the form of infrared light. The efficiency of mini IR LEDs is high due to their small size, which minimizes energy loss and heat generation.
