Infrared Power LED: A Revolution in Lighting Technology

The advent of infrared power LED has marked a significant milestone in the field of lighting technology. As a highly efficient and versatile lighting solution, infrared power LED has found its way into various industries, including automotive, medical, and consumer electronics. This article aims to provide an in-depth introduction to infrared power LED, covering its working principle, advantages, applications, and market trends.

Working Principle of Infrared Power LED

Infrared power LED, also known as infrared LED, is a type of semiconductor device that emits infrared light. It operates on the principle of electroluminescence, where an electric current passes through a semiconductor material, causing it to emit light. The key components of an infrared power LED include a p-n junction, a chip, and a package. The p-n junction is the core of the infrared power LED. When an electric current is applied, electrons and holes are separated at the junction, creating a potential difference. This potential difference drives the electrons towards the n-region, where they recombine with the holes, releasing energy in the form of photons. These photons are then emitted as infrared light. The chip is the semiconductor material that forms the p-n junction. It is typically made of gallium arsenide (GaAs), gallium nitride (GaN), or other suitable materials. The quality and composition of the chip greatly influence the performance of the infrared power LED. The package is used to protect the chip and enhance its performance. It also helps in dissipating heat and ensuring electrical contact between the LED and the circuit.
