Introduction to Infrared IR LED Technology

Infrared IR LED: A Brief Overview

The infrared IR LED, or infrared light-emitting diode, is a crucial component in various applications ranging from consumer electronics to industrial automation. It operates on the principle of emitting infrared light, which is a type of electromagnetic radiation with wavelengths longer than those of visible light but shorter than those of microwave radiation. This technology has seen significant advancements in recent years, making it an integral part of numerous devices and systems.

How Infrared IR LED Works

An infrared IR LED is a semiconductor device that emits infrared light when an electric current is applied to it. The process begins with a p-n junction, where electrons from the n-type semiconductor recombine with holes from the p-type semiconductor. This recombination releases energy in the form of photons, which are then emitted as infrared light. The color of the emitted light depends on the material composition of the LED, with different materials emitting light at different wavelengths.
