Introduction to Infrared Fill Light LEDs

What are Infrared Fill Light LEDs?

Infrared fill light LEDs, also known as infrared LED fill lights, are a type of light source that emits infrared radiation. Unlike traditional visible light sources, infrared fill light LEDs emit light in the infrared spectrum, which is beyond the range of human vision. These LEDs have gained significant attention in various industries, particularly in photography, videography, and medical applications. In this article, we will explore the features, benefits, and applications of infrared fill light LEDs.

How Do Infrared Fill Light LEDs Work?

Infrared fill light LEDs work by converting electrical energy into infrared radiation through the process of electroluminescence. When an electric current passes through a semiconductor material, such as gallium nitride (GaN) or aluminum gallium indium phosphide (AlGaInP), it excites the electrons within the material. These excited electrons recombine with holes, releasing energy in the form of photons. The photons emitted by the semiconductor material fall within the infrared spectrum, resulting in infrared fill light.
