Innovative Advancements in Infrared Light LEDs: Unveiling the Future of Technology

Infrared light LEDs, also known as infrared emitting diodes, are semiconductor devices that emit infrared light when an electric current passes through them. They are widely used in various applications, including consumer electronics, automotive, industrial, and medical fields. This article aims to provide an in-depth introduction to the infrared light LED industry, covering its history, technology, applications, and future prospects.

History of Infrared Light LEDs

The concept of infrared light was first discovered by Sir Isaac Newton in the 17th century. However, it was not until the late 19th century that the idea of using semiconductors to generate infrared light was proposed. In 1906, Henry Joseph Round, a British physicist, demonstrated the first infrared emitting diode by using a selenium cell. It was not until the 1960s that the first practical infrared light LED was developed by Nick Holonyak Jr., an American physicist.

Technology of Infrared Light LEDs

Infrared light LEDs are made of semiconductor materials, such as gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). The structure of an infrared light LED typically consists of a p-n junction, where electrons and holes recombine and emit infrared light. The key factors that affect the performance of infrared light LEDs include the semiconductor material, the thickness of the active layer, and the doping concentration.
