Introduction to IR LED Lights

What are IR LED Lights?

Infrared Light Emitting Diodes (IR LEDs) are semiconductor devices that emit light in the infrared spectrum. Unlike visible light, infrared light is not visible to the human eye, but it can be detected by specialized sensors and cameras. IR LEDs are widely used in various applications due to their efficiency, compact size, and ability to emit light in a specific wavelength range.

How Do IR LEDs Work?

IR LEDs work on the principle of the PN junction. When an electric current is applied to the PN junction, electrons and holes recombine, releasing energy in the form of photons. The wavelength of the emitted light depends on the material composition of the PN junction. In the case of IR LEDs, the material is typically made of gallium arsenide (GaAs) or aluminum gallium arsenide (AlGaAs), which emit light in the infrared range.
