810 nm high power LED, also known as the 810nm high power LED, is a cutting-edge technology in the field of optoelectronics. As a new type of LED, it has attracted widespread attention from the industry due to its unique advantages. This article will introduce the 810 nm high power LED from several aspects, including its working principle, application fields, market prospects, and challenges faced by the industry.

Working Principle of 810 nm High Power LED

The working principle of the 810 nm high power LED is similar to that of other types of LEDs. It is based on the principle of electroluminescence, which is the process of emitting light when a material is excited by electricity. The 810 nm high power LED is made of a semiconductor material, usually gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which has a bandgap of 1.3 eV at room temperature. When a forward voltage is applied to the LED, electrons and holes are injected into the semiconductor material, and they recombine at the recombination zone. During the recombination process, the excess energy is released in the form of light, resulting in the emission of 810 nm light.
