History of Infrared LED Light Technology
The concept of infrared light dates back to the early 19th century when scientists discovered that invisible light waves could be emitted by certain materials. However, it wasn’t until the late 20th century that the technology for producing infrared LED lights became practical. The first infrared LED was developed in the 1960s, and since then, the technology has evolved significantly, with numerous advancements in terms of efficiency, brightness, and cost-effectiveness.
How Infrared LED Light Works
Infrared LED lights work by emitting infrared radiation through a semiconductor material. When an electric current is applied to the semiconductor, it releases energy in the form of photons. These photons are in the infrared spectrum, which is just beyond the visible light spectrum. The semiconductor material used in infrared LEDs is typically made of gallium arsenide (GaAs), gallium phosphide (GaP), or aluminum gallium arsenide (AlGaAs).
