In this article, we will delve into the world of infrared LED light, exploring its applications, advantages, and the technology behind it.

How Infrared LED Light Works

Infrared LED light works on the principle of photoelectric effect. When an electric current is applied to an LED, electrons are excited and move from the valence band to the conduction band. When these electrons return to the valence band, they release energy in the form of photons. In the case of infrared LED light, these photons have a longer wavelength and lower energy than visible light, resulting in the emission of infrared radiation. The process of emitting infrared light involves the following steps: 1. Electron injection: When an electric current is applied to the LED, electrons are injected from the n-type semiconductor to the p-type semiconductor. 2. Recombination: Electrons recombine with holes in the p-type semiconductor, releasing energy in the form of photons. 3. Emission of infrared radiation: The photons have longer wavelengths and lower energy, resulting in the emission of infrared light.
