High power LED 780 nm, also known as the near-infrared (NIR) spectrum, has emerged as a significant player in the optoelectronics industry. This specialized LED emits light at a wavelength of 780 nm, which falls within the NIR range. This article delves into the details of high power LED 780 nm technology, its applications, market trends, and the challenges and opportunities it presents in the industry.

Introduction to High Power LED 780 nm

High power LED 780 nm refers to a type of light-emitting diode (LED) that can produce a high intensity of light at a specific wavelength of 780 nm. Unlike visible light LEDs, which emit light in the range of 400 to 700 nm, high power NIR LEDs are designed to operate in the infrared region. This makes them ideal for applications that require light in the NIR spectrum, such as medical diagnostics, industrial automation, and optical communication.

Working Principle of High Power LED 780 nm

The working principle of high power LED 780 nm is based on the semiconductor physics of gallium nitride (GaN) or aluminum gallium nitride (AlGaN) materials. These materials have a direct bandgap, which allows them to efficiently emit light at the desired wavelength when an electric current is applied. The LED structure typically consists of a p-n junction, where the p-type layer is doped with acceptor atoms and the n-type layer with donor atoms. When an electric current flows through the p-n junction, electrons and holes recombine, releasing energy in the form of photons at the bandgap energy of the material.

Applications of High Power LED 780 nm

The unique properties of high power LED 780 nm make it suitable for a wide range of applications: 1. Medical Diagnostics: NIR light is used in various medical imaging techniques, such as near-infrared spectroscopy (NIRS) and optical coherence tomography (OCT).
