High power LED 780 nm has become a significant topic in the industry due to its wide range of applications and superior performance. This article aims to provide an in-depth introduction to the high power LED 780 nm, covering its basic principles, applications, advantages, and market trends.

Basic Principles of High Power LED 780 nm

High power LED 780 nm refers to a type of LED with a peak emission wavelength of 780 nm. It belongs to the near-infrared (NIR) spectrum, which is invisible to the human eye. The basic principle of high power LED 780 nm is based on the semiconductor materials and the quantum efficiency of the LED. The core material of high power LED 780 nm is typically gallium nitride (GaN) or its alloys. When the forward bias voltage is applied to the semiconductor material, electrons and holes are injected into the active region. Through the recombination of electrons and holes, photons with a wavelength of 780 nm are emitted. This process is known as electroluminescence.
