In this article, we will delve into the intricacies of the IR Emitter LED, its working principles, and its numerous applications across different sectors.

Working Principles of IR Emitter LED

The IR Emitter LED operates on the principle of semiconductor physics. It consists of a p-n junction, where electrons and holes recombine, releasing energy in the form of infrared light. When an electric current is applied to the diode, electrons move from the n-type material to the p-type material, creating a depletion region. This region prevents the flow of electric current and generates infrared light. The key components of an IR Emitter LED include the semiconductor material, a p-n junction, a metal contact, and a transparent encapsulant. The semiconductor material, typically gallium arsenide (GaAs) or gallium phosphide (GaP), determines the wavelength of the emitted light. The metal contact provides a path for the electric current, while the transparent encapsulant protects the diode and enhances its light emission.
