LED IR 850nm, or Infrared Light Emitting Diode at 850 nanometers, has become a significant component in the field of infrared technology. This type of LED emits light in the near-infrared spectrum, which is invisible to the human eye but can be detected by various sensors and devices. The following article delves into the industry, its applications, and the technological advancements surrounding LED IR 850nm.

Introduction to LED IR 850nm

LED IR 850nm is a type of LED that emits light at a wavelength of 850 nanometers. This wavelength falls within the near-infrared range, which is just beyond the red end of the visible spectrum. The primary advantage of this wavelength is its ability to penetrate certain materials and surfaces, making it ideal for various applications such as remote controls, surveillance, and communication systems.

How LED IR 850nm Works

LED IR 850nm operates on the principle of the semiconductor diode. When an electric current is applied to the diode, it emits light. The specific wavelength of the emitted light is determined by the composition of the semiconductor material used in the diode. In the case of LED IR 850nm, the semiconductor material is designed to emit light at 850 nanometers. The process begins with the injection of electrons into the semiconductor material. These electrons then recombine with electron holes, releasing energy in the form of photons. The energy released corresponds to the energy difference between the valence and conduction bands of the semiconductor material. Since the energy of the photons emitted by LED IR 850nm is in the near-infrared range, the light is invisible to the human eye.
