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 nm. The working principle of an LED is based on the recombination of electrons and holes in a semiconductor material. When electrons and holes recombine, they release energy in the form of photons, which produce light. The 810 nm high power LED is typically made of a gallium-nitride (GaN) material, which has excellent optical and electrical properties. The GaN material is doped with indium (In) to create a p-type region and with gallium (Ga) to create an n-type region. The recombination of electrons and holes in the p-n junction region generates the 810 nm light.
