High power IR LED 940nm has emerged as a crucial component in various industries, offering a range of applications from remote controls to medical imaging. This article delves into the details of high power IR LED 940nm, exploring its technology, applications, market trends, and future prospects.

Introduction to High Power IR LED 940nm

High power IR LED 940nm, also known as infrared LED, is a type of light-emitting diode that emits infrared radiation at a wavelength of 940 nanometers. These LEDs are designed to provide high intensity light output, making them ideal for applications that require long-range detection and transmission. The 940nm wavelength falls within the near-infrared spectrum, which is not visible to the human eye but can be detected by various sensors and devices.

Technology and Working Principle

The technology behind high power IR LED 940nm involves the use of semiconductor materials that emit light when an electric current passes through them. These materials are typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs) and are grown using techniques like molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). The diode structure consists of a p-n junction, where the n-type material has an excess of electrons and the p-type material has an excess of holes. When an electric current is applied, electrons and holes recombine at the p-n junction, releasing energy in the form of photons. The wavelength of the emitted light is determined by the energy bandgap of the semiconductor material. In the case of 940nm IR LEDs, the bandgap is carefully engineered to produce light at the desired wavelength.
