Basic Principles of 810 nm High Power LED

The 810 nm high power LED is a type of light-emitting diode (LED) that emits light at a wavelength of 810 nanometers. This technology is based on the principle of semiconductor physics, where electrons and holes recombine in a semiconductor material to emit photons. The 810 nm wavelength falls within the infrared region of the electromagnetic spectrum, making it suitable for various applications such as optical communication, medical imaging, and remote sensing. In a 810 nm high power LED, the semiconductor material typically used is a combination of gallium arsenide (GaAs) and indium gallium arsenide (InGaAs). These materials have a direct bandgap, which allows for efficient light emission at the desired wavelength. The structure of a 810 nm high power LED usually consists of a p-n junction, with the n-type region containing a high concentration of acceptor impurities and the p-type region containing a high concentration of donor impurities. When an electric current is applied, electrons from the n-type region are injected into the p-type region, where they recombine with holes to produce light.
