This article aims to provide an in-depth introduction to high power infrared LED 850nm, covering its working principle, applications, market trends, and future prospects.

Introduction to High Power Infrared LED 850nm

High power infrared LED 850nm refers to an LED that emits infrared light at a wavelength of 850 nanometers. It is a type of light-emitting diode (LED) that uses a semiconductor material to convert electrical energy into light. The 850nm wavelength is within the near-infrared region of the electromagnetic spectrum, which is invisible to the human eye. This makes it an ideal choice for applications that require covert or long-range communication.

Working Principle of High Power Infrared LED 850nm

The working principle of a high power infrared LED 850nm is based on the quantum mechanical properties of the semiconductor material. When an electrical current is applied to the LED, electrons and holes are injected into the active region of the semiconductor. As these charge carriers recombine, they release energy in the form of photons. The wavelength of the emitted light is determined by the energy difference between the conduction band and the valence band of the semiconductor material. In the case of high power infrared LED 850nm, the semiconductor material typically used is aluminum gallium arsenide (AlGaAs) or aluminum indium gallium phosphide (AlInGaP). These materials have a direct bandgap structure, which allows for efficient light emission at the desired 850nm wavelength.
