Revolutionize Your Projects with the Latest IR LED Diode Technology

IR LED Diode, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. With the rapid development of technology, IR LED Diodes have become an indispensable component in various fields, such as consumer electronics, automotive, medical, and industrial applications. This article will provide an in-depth introduction to the IR LED Diode industry, covering its basic principles, types, applications, and market trends.

Basic Principles of IR LED Diode

The working principle of an IR LED Diode is based on the semiconductor physics. When a forward bias voltage is applied to the PN junction, electrons and holes are injected into the depletion region. Due to the recombination of electrons and holes, energy is released in the form of photons. The energy band gap of the semiconductor material determines the wavelength of the emitted light. In the case of IR LED Diodes, the energy band gap is typically between 0.8 and 3.0 eV, resulting in the emission of infrared light with a wavelength ranging from 780 nm to 3000 nm.
