Revolutionizing Lighting Technology: The Emergence of Broadband IR LED Innovations

Broadband IR LED, or Infrared Light Emitting Diode, has become an essential component in various industries due to its unique properties and wide range of applications. This article aims to provide an in-depth introduction to the broadband IR LED industry, covering its history, technology, applications, market trends, and future prospects.

History of Broadband IR LED

The history of infrared technology dates back to the early 20th century. In the 1930s, infrared radiation was first discovered, and its applications in various fields began to emerge. The development of infrared technology accelerated in the 1950s, with the invention of the first infrared LED. Over the years, the technology has evolved, and the broadband IR LED has become a key component in many applications.

Technology of Broadband IR LED

Broadband IR LED is a type of semiconductor device that emits infrared light in a broad spectrum. The key to its technology lies in the semiconductor material and its structure. The most commonly used semiconductor materials for broadband IR LED are gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs). These materials have excellent optical and electrical properties, making them ideal for infrared emission.

The structure of a broadband IR LED typically consists of a p-n junction, which is formed by doping the semiconductor material with impurities. When an electric current is applied to the p-n junction, electrons and holes are generated, and the recombination of these carriers results in the emission of infrared light. The broad spectrum of the emitted light is due to the differences in the energy levels of the semiconductor material.
