Infrared LED Technology: Enhance Your Projects with Cutting-Edge Lighting

Infrared LED, short for infrared light-emitting diode, is a type of semiconductor device that emits infrared light when an electric current passes through it. It is widely used in various fields, such as consumer electronics, automotive, medical, and industrial applications. This article aims to provide an in-depth introduction to the infrared LED industry, covering its history, technology, applications, and market trends.

History of Infrared LED

The concept of infrared light was discovered by British scientist Willian Herschel in 1800. Later, in 1906, the first infrared LED was developed by the British physicist William Edward Hansell. However, it was not until the 1970s that the infrared LED industry began to take off, thanks to the advancements in semiconductor technology. Since then, infrared LED technology has continued to evolve, and its applications have expanded into various fields.

Technology of Infrared LED

Infrared LED technology is based on the principle of semiconductor physics. When an electric current passes through a semiconductor material, electrons and holes are generated. When these electrons and holes recombine, they release energy in the form of light. In the case of infrared LED, the energy released is in the infrared spectrum, which is not visible to the human eye.

The core component of an infrared LED is the semiconductor material. Different materials, such as gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium arsenide (AlGaAs), are used to create infrared LEDs with different wavelengths and characteristics. The key factors that affect the performance of an infrared LED include its wavelength, brightness, and efficiency.
