850nm infrared LED (light-emitting diode) is a type of semiconductor device that emits infrared light at a wavelength of 850 nanometers. As a part of the infrared spectrum, it has gained significant attention in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to the 850nm infrared LED industry, covering its technology, market trends, and future prospects.

Technology and Working Principle of 850nm Infrared LED

The 850nm infrared LED is a semiconductor device that utilizes the bandgap of a semiconductor material to emit infrared light. The bandgap is the energy difference between the valence band and the conduction band of a semiconductor. When an electric current passes through the semiconductor, electrons are excited from the valence band to the conduction band. As the electrons return to the valence band, they release energy in the form of photons, which are infrared light at 850nm.

One of the key advantages of the 850nm infrared LED is its ability to emit light at a specific wavelength. This makes it ideal for applications that require precise control of the emitted light, such as communication, sensing, and medical imaging. The working principle of the 850nm infrared LED is based on the following steps:

1. Electrical energy is applied to the semiconductor material, causing electrons to move from the valence band to the conduction band.
2. When electrons return to the valence band, they release energy in the form of photons.
3. The photons are emitted as infrared light at a wavelength of 850nm.
