Introduction to High Power LED 850nm

High power LED 850nm refers to a type of light-emitting diode (LED) that emits light at a wavelength of 850 nanometers. These LEDs are known for their high luminous intensity and are widely used in various applications, including medical, industrial, and automotive sectors. The 850nm wavelength falls within the infrared spectrum, making it invisible to the human eye.

Technology Behind High Power LED 850nm

The technology behind high power LED 850nm involves the use of gallium nitride (GaN) as the semiconductor material. GaN is a wide-bandgap semiconductor, which allows it to emit light at higher wavelengths compared to other semiconductor materials like silicon or gallium arsenide (GaAs). The process of manufacturing high power LED 850nm involves several steps, including epitaxial growth, device fabrication, and packaging. During epitaxial growth, a thin layer of GaN is deposited on a substrate material, typically sapphire or silicon carbide (SiC). This layer is then doped with various impurities to create p-n junctions, which are responsible for the emission of light. The device fabrication process involves creating a p-n junction within the GaN layer and attaching metal contacts to facilitate the flow of current. Finally, the LED is packaged to protect it from environmental factors and enhance its performance.
