Ultra bright IR LED, short for Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared light. It has become increasingly popular in various industries due to its high brightness, long lifespan, and low power consumption. This article aims to provide an in-depth introduction to the ultra bright IR LED industry, covering its history, technology, applications, and market trends.

History of Ultra Bright IR LED

The concept of infrared light was first discovered by British physicist Willian Herschel in 1800. Since then, infrared technology has been continuously developed and applied in various fields. In the 1960s, the invention of the LED (Light Emitting Diode) marked the beginning of a new era for infrared technology. With the continuous optimization of materials and structures, the brightness of IR LED has been significantly improved, leading to the birth of ultra bright IR LED.

Technology of Ultra Bright IR LED

The ultra bright IR LED is a semiconductor device that emits infrared light when an electric current passes through it. The key to its high brightness lies in the material and structure design. The most commonly used materials for ultra bright IR LED are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium nitride (InGaN). These materials have excellent optical properties and can emit high-intensity infrared light. The structure of ultra bright IR LED mainly includes the active region, the p-type layer, the n-type layer, and the encapsulation layer. The active region is the core part of the LED, where the electron-hole recombination occurs and emits light. The p-type layer and the n-type layer are used to form a p-n junction, which controls the flow of electrons and holes. The encapsulation layer is used to protect the LED from external damage and improve its heat dissipation performance.
