This article delves into the world of IR LED diodes, exploring their applications, advantages, and future prospects.

What is an IR LED Diode? An IR LED diode, also known as an infrared light-emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. Unlike visible light, infrared light is not visible to the naked eye, making it ideal for secure communication. IR LED diodes are commonly used in remote controls, consumer electronics, and various industrial applications.

How Does an IR LED Diode Work? An IR LED diode consists of a P-N junction, where the P-type and N-type semiconductor materials are combined. When an electric current flows through the diode, electrons from the N-type material recombine with holes from the P-type material. This recombination process releases energy in the form of infrared light. The intensity of the emitted light depends on the forward voltage applied to the diode. As the forward voltage increases, the intensity of the emitted light also increases. IR LED diodes are available in various wavelengths, ranging from 780 nm to 3,000 nm, with different applications requiring specific wavelengths.
