Introducing IR Infrared LED: A Revolution in Illumination Technology

Introduction to IR Infrared LED

The IR infrared LED, or infrared light-emitting diode, has emerged as a revolutionary technology in the field of illumination. These diodes emit light in the infrared spectrum, which is beyond the visible range of human eyes. This unique characteristic has opened up a plethora of applications across various industries, from consumer electronics to industrial automation. In this article, we will explore the world of IR infrared LED, its working principles, advantages, applications, and future trends.

How IR Infrared LED Works

An IR infrared LED operates based on the principle of semiconductor physics. When a current is applied to the diode, electrons and holes are excited, and as they recombine, they emit photons in the infrared region. This process is known as electroluminescence. The emitted light has a wavelength range of 700 nm to 1 mm, which is invisible to the human eye but detectable by sensors and other devices. The key components of an IR infrared LED include a semiconductor material, a p-n junction, and a lead frame. The semiconductor material is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs), which allows for efficient light emission in the infrared spectrum. The p-n junction is formed by doping the semiconductor material with impurities to create a region with excess electrons (n-type) and holes (p-type). When a voltage is applied, electrons from the n-type region move to the p-type region, recombining with holes and emitting photons in the process.
