LED 850nm: Cutting-Edge Technology and Applications Unveiled

LED 850nm, also known as near-infrared (NIR) LED, has been increasingly gaining attention in the industry due to its unique properties and wide range of applications. This article aims to provide a comprehensive introduction to the LED 850nm market, covering its technology, applications, market trends, and future prospects.

Introduction to LED 850nm Technology

LED 850nm refers to an LED that emits light at a wavelength of 850 nanometers. Unlike visible light, NIR light is not visible to the human eye, making it ideal for various applications where visibility is not required. The 850nm wavelength falls within the NIR range, which is known for its strong penetration ability and low light absorption by human skin.

The technology behind LED 850nm involves the use of a semiconductor material called gallium nitride (GaN) as the active layer. GaN is a III-Nitride semiconductor, which is known for its high thermal conductivity and excellent electrical properties. The LED 850nm chip is typically composed of a p-type GaN layer, an n-type GaN layer, and a p-type GaN layer, with an indium gallium nitride (InGaN) quantum well layer in between.

The InGaN quantum well layer plays a crucial role in the emission of NIR light at 850nm. When an electrical current is applied to the LED, electrons and holes recombine in the quantum well, releasing energy in the form of photons. The 850nm wavelength is achieved by carefully controlling the composition and thickness of the InGaN quantum well layer.

Applications of LED 850nm

LED 850nm has found numerous applications across various industries due to its unique properties. Some of the key applications include:
