Introduction to Infrared 850 LED Lamp

What is an Infrared 850 LED Lamp?

An infrared 850 LED lamp is a type of light-emitting diode (LED) that emits infrared radiation at a wavelength of 850 nanometers (nm). Unlike visible light, infrared radiation is not visible to the human eye. However, it is widely used in various applications, including remote controls, night vision devices, and medical equipment. The 850 nm wavelength is particularly popular due to its excellent performance in these applications.

How Does an Infrared 850 LED Lamp Work?

An infrared 850 LED lamp works on the principle of electroluminescence. When an electric current passes through a semiconductor material, it generates light. In the case of an infrared 850 LED lamp, the semiconductor material is typically gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs). When the current flows through the material, it excites the electrons, causing them to recombine with the holes in the lattice structure. This recombination process releases energy in the form of photons, which are then emitted as infrared radiation.

Applications of Infrared 850 LED Lamps

Infrared 850 LED lamps have a wide range of applications, thanks to their unique properties. Some of the most common uses include: 1. Remote Controls: Infrared 850 LED lamps are widely used in remote controls for TVs, air conditioners, and other electronic devices.
