Introduction to Infrared LED Lamp Beads

What are Infrared LED Lamp Beads?

Infrared LED lamp beads, also known as infrared LED diodes, are a type of light-emitting diode (LED) that emits infrared light. Unlike visible light, infrared light is not visible to the human eye. These lamp beads are widely used in various applications due to their unique properties and benefits. In this article, we will explore the industry of infrared LED lamp beads, including their working principle, applications, advantages, and market trends.

Working Principle of Infrared LED Lamp Beads

Infrared LED lamp beads work on the principle of semiconductor physics. When an electric current passes through a semiconductor material, such as gallium arsenide (GaAs) or indium gallium arsenide (InGaAs), it generates infrared light. The semiconductor material used in infrared LED lamp beads has a direct bandgap, which allows the emission of infrared light with a specific wavelength. The process of emitting infrared light involves the following steps: 1. An electric current is applied to the semiconductor material. 2. The electrons in the material gain energy and move to a higher energy level. 3. When the electrons return to their original energy level, they release energy in the form of infrared light. The wavelength of the emitted infrared light depends on the semiconductor material and its composition. Infrared LED lamp beads are available in various wavelengths, ranging from 780nm to 3000nm.
