Introducing the Infrared Patch LEDs: Revolutionizing the World of Lighting and Communication

Introduction to Infrared Patch LEDs

Infrared patch LEDs (light-emitting diodes) are a type of semiconductor device that emits infrared light when an electric current is applied. These compact and energy-efficient devices have found wide applications in various industries, including automotive, medical, consumer electronics, and industrial automation. The advancements in infrared patch LED technology have not only improved the efficiency of lighting systems but also enhanced the capabilities of communication devices. This article aims to provide an in-depth introduction to infrared patch LEDs, exploring their working principles, advantages, applications, and future prospects.

Working Principles of Infrared Patch LEDs

Infrared patch LEDs are based on the principle of electroluminescence, where an electric current excites electrons within a semiconductor material, causing them to recombine and emit photons. These photons have a longer wavelength than visible light, falling within the infrared spectrum. The semiconductor material used in infrared patch LEDs is typically a compound semiconductor, such as gallium arsenide (GaAs), gallium nitride (GaN), or aluminum gallium indium phosphide (AlGaInP).

When an electric current is applied to the semiconductor material, electrons and holes are injected into the active region of the LED. The recombination of these charge carriers results in the emission of infrared photons. The intensity of the emitted light depends on various factors, such as the semiconductor material, the current density, and the temperature.
