With the rapid development of technology, infrared (IR) LEDs have become increasingly important in various applications, especially in the 950nm wavelength range. IR LED 950nm, known for its long wavelength and deep penetration capabilities, has found its way into numerous fields, including security, medical, automotive, and industrial sectors. This article aims to provide an in-depth introduction to the IR LED 950nm industry, covering its technology, applications, market trends, and future prospects.

Technology of IR LED 950nm

IR LED 950nm refers to an infrared light-emitting diode that emits light at a wavelength of 950nm. Unlike visible light, which ranges from 400nm to 700nm, IR light is not visible to the human eye. The 950nm wavelength falls within the far infrared region, which is characterized by its ability to penetrate through certain materials and surfaces, making it ideal for specific applications.

The technology behind the IR LED 950nm involves the use of gallium nitride (GaN) or aluminum gallium nitride (AlGaN) as the semiconductor material. These materials are known for their excellent electrical and thermal properties, which enable the efficient conversion of electrical energy into infrared light. The structure of an IR LED typically consists of a p-n junction, where electrons and holes recombine to emit photons at the 950nm wavelength.

Manufacturing IR LED 950nm involves several key steps, including epitaxial growth, wafer fabrication, and packaging. Epitaxial growth is the process of depositing a thin layer of semiconductor material on a substrate to create a layered structure. Wafer fabrication includes processes such as doping, diffusion, and etching to create the desired electrical properties. Finally, the packaged LED is tested for performance and quality control before being shipped to customers.
