Infrared LED 5mm: A Comprehensive Industry Overview

Introduction to Infrared LED 5mm

The 5mm infrared LED (light-emitting diode) has become a staple in various industries due to its compact size, efficiency, and versatility. These LEDs emit infrared light, which is invisible to the human eye but has numerous applications in technology and consumer products. This article provides a comprehensive overview of the infrared LED 5mm market, its technology, applications, and future prospects.

What is an Infrared LED 5mm?

An infrared LED 5mm is a type of semiconductor device that emits infrared light when an electric current passes through it. The term "5mm" refers to the diameter of the LED's housing, which is typically 5 millimeters. These LEDs are designed to produce a narrow beam of infrared light, which is useful for specific applications that require precise focusing.

How Does an Infrared LED 5mm Work?

The working principle of an infrared LED 5mm is based on the semiconductor material, usually gallium arsenide (GaAs), which emits light when electrons recombine with electron holes. When a forward bias is applied to the LED, electrons and holes are pushed towards the p-n junction, where they recombine and release energy in the form of infrared light. The size of the LED housing determines the intensity and focus of the emitted light.
