Introduction to Infrared LED Light

What is Infrared LED Light?

Infrared LED light, also known as infrared diode, is a type of semiconductor light-emitting diode that emits infrared radiation. Unlike visible light, infrared light is not visible to the naked eye. It has a longer wavelength than visible light and is typically used in various applications that require invisible light for communication, sensing, and illumination. Infrared LED lights are widely used in various industries due to their unique properties, such as low power consumption, long lifespan, and high efficiency. They are available in different wavelengths, ranging from near-infrared (NIR) to far-infrared (FIR), depending on the specific application.

How Does Infrared LED Light Work?

Infrared LED light works on the principle of the photoelectric effect. When an electric current is applied to a semiconductor material, electrons are excited and move to higher energy levels. When these electrons return to their original energy levels, they release energy in the form of photons. In the case of infrared LED lights, these photons have longer wavelengths, which fall within the infrared spectrum. The semiconductor material used in infrared LED lights is typically made of gallium arsenide (GaAs), gallium nitride (GaN), or indium gallium nitride (InGaN). These materials have high electron mobility and can efficiently convert electrical energy into infrared light.
