Introduction to 850 Infrared Lamp Beads

What are 850 Infrared Lamp Beads?

850 infrared lamp beads, also known as 850nm infrared LEDs, are a type of semiconductor device that emits infrared light at a specific wavelength of 850 nanometers. These lamp beads are widely used in various applications due to their unique properties, such as high efficiency, low power consumption, and long lifespan. In this article, we will delve into the details of 850 infrared lamp beads, their applications, and the industry surrounding them.

How Do 850 Infrared Lamp Beads Work?

850 infrared lamp beads work on the principle of electroluminescence. When an electric current passes through the semiconductor material, it generates heat, which excites the electrons within the material. As the electrons return to their original state, they release energy in the form of photons. These photons are then emitted as infrared light at a wavelength of 850nm. The semiconductor material used in 850 infrared lamp beads is typically gallium arsenide (GaAs) or gallium nitride (GaN), which are known for their excellent thermal conductivity and electrical properties. The structure of the lamp bead usually consists of a p-n junction, which is responsible for the generation of infrared light.
