Introducing Infrared Patch LEDs: The Cutting-Edge Technology Revolutionizing Various Industries

Introduction to Infrared Patch LEDs

Infrared patch LEDs, also known as infrared surface mount diodes, have emerged as a cutting-edge technology that has been revolutionizing various industries. These compact and efficient devices emit infrared light, which is invisible to the human eye, and have become an essential component in numerous applications. This article aims to provide an in-depth introduction to infrared patch LEDs, their working principles, advantages, and applications across different sectors.

Working Principles of Infrared Patch LEDs

Infrared patch LEDs are semiconductor devices that utilize the principles of electroluminescence to generate infrared light. When a forward voltage is applied across the diode, electrons and holes recombine in the active region, releasing energy in the form of photons. These photons have a longer wavelength than visible light, falling within the infrared spectrum. The working principle of an infrared patch LED can be summarized as follows: 1. An electrical current is supplied to the diode. 2. The diode emits infrared light as a result of the recombination of electrons and holes. 3. The emitted light can be controlled by adjusting the forward voltage and current.
