High power infrared LEDs, also known as infrared diodes, have become increasingly popular in various industries due to their ability to emit intense infrared light. These LEDs are widely used in applications such as automotive, medical, industrial, and consumer electronics. This article provides an in-depth introduction to the high power infrared LED industry, covering their working principles, advantages, applications, and market trends.

Working Principles of High Power Infrared LEDs

High power infrared LEDs are based on the principle of semiconductor physics. They are made of gallium arsenide (GaAs), gallium nitride (GaN), or other III-V compound semiconductors. When an electric current is applied to the semiconductor material, electrons and holes are generated. When these electrons and holes recombine, they release energy in the form of photons. The wavelength of these photons falls within the infrared spectrum, making them ideal for various applications. The structure of a high power infrared LED typically consists of a p-n junction, a p-type layer, an n-type layer, and a metal contact. The p-n junction is the core of the LED, where the recombination of electrons and holes occurs. The metal contact is used to apply the electric current to the LED. The quality of the semiconductor material and the design of the LED structure directly affect the performance of the high power infrared LED.
