Infrared LED light, also known as infrared diode, is a type of semiconductor light source that emits light in the infrared spectrum. These lights are widely used in various industries due to their unique properties and applications. This article aims to provide a comprehensive introduction to the infrared LED light industry, covering its history, technology, applications, market trends, and future prospects.

History of Infrared LED Light

The concept of infrared light has been known for centuries, but it was not until the late 19th century that scientists began to study the properties of infrared radiation. In 1906, Henry Joseph Round, an English physicist, discovered that a selenium cell could generate a voltage when exposed to infrared light. This discovery laid the foundation for the development of infrared detectors. In the 1960s, the invention of the light-emitting diode (LED) technology revolutionized the way infrared light is generated and used. The first infrared LED was developed by Nick Holonyak Jr. at General Electric in 1962.

Technology of Infrared LED Light

Infrared LED lights are made from a semiconductor material, typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). The semiconductor material is sandwiched between two electrodes, and when a voltage is applied, electrons and holes recombine, releasing energy in the form of infrared light. The color of the light emitted depends on the bandgap of the semiconductor material. For example, a GaAs LED emits near-infrared light, while an AlGaAs LED emits mid-infrared light.

Modern infrared LED technology has made significant advancements, including increased light output, improved efficiency, and reduced cost. The development of quantum wells and quantum dots has allowed for the creation of LEDs with a wider range of wavelengths and higher brightness. Additionally, the use of phosphors can convert infrared light to visible light, making it more versatile for various applications.
