Introducing the infrared LED 5mm, a compact and efficient component that has become increasingly popular in various applications across numerous industries. This article delves into the world of infrared LED 5mm, exploring its features, applications, and the technological advancements that have made it a staple in the electronics industry.

What is an Infrared LED 5mm?

An infrared LED 5mm, also known as an IR LED, is a type of light-emitting diode (LED) that emits infrared light at a wavelength of approximately 780 to 1000 nanometers. The "5mm" refers to the diameter of the LED's lens, which is a standard size for many LED components. These LEDs are designed to emit light in the infrared spectrum, which is invisible to the human eye but can be detected by specialized sensors and cameras.

How Does an Infrared LED 5mm Work?

Infrared LEDs work on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. When a forward voltage is applied to the LED, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. In the case of infrared LEDs, these photons fall within the infrared spectrum, making them ideal for applications where visible light is not required or where it could interfere with the system.
