LED infrared technology has emerged as a revolutionary innovation in the field of lighting and has found applications in various industries. This article aims to provide an in-depth introduction to LED infrared, its working principles, applications, advantages, and future prospects.

Introduction to LED Infrared

LED infrared, also known as LED infrared diode, is a type of light-emitting diode (LED) that emits infrared light. Unlike traditional infrared sources, LED infrared has several advantages, such as energy efficiency, long lifespan, and compact size. The infrared light emitted by LED infrared is invisible to the human eye but can be detected by sensors and other devices.

Working Principles of LED Infrared

LED infrared operates on the principle of electroluminescence. When an electric current passes through the semiconductor material, it generates heat, which excites the electrons and releases photons. These photons are then emitted as infrared light. The color of the emitted light depends on the material used in the LED infrared diode.
