High intensity IR LED, or Infrared Light Emitting Diode, has become a crucial component in various industries due to its exceptional performance and wide range of applications. This article aims to provide an in-depth introduction to the high intensity IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of High Intensity IR LED

The concept of infrared light has been known for centuries, but it was not until the late 19th century that the first infrared light emitting diode was developed. In 1962, Nick Holonyak, a physicist at General Electric, successfully created the first practical infrared LED. Since then, the technology has evolved significantly, with continuous improvements in efficiency, brightness, and lifespan. Today, high intensity IR LED technology has become an integral part of many industries.

Technology of High Intensity IR LED

High intensity IR LED technology is based on the principle of semiconductor physics. When a forward voltage is applied to a semiconductor material, electrons and holes are injected into the depletion region, leading to the recombination of electrons and holes. During this process, energy is released in the form of photons, which are emitted as infrared light. The key to high intensity IR LED technology lies in the selection of semiconductor materials and the design of the LED structure. The most commonly used semiconductor materials for high intensity IR LED are gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium indium phosphide (AlGaInP). These materials have excellent optical and electrical properties, making them ideal for infrared light emission. The LED structure typically consists of a p-n junction, with the p-type layer emitting infrared light and the n-type layer absorbing excess electrons.
