Understanding Infrared LED Lights
Infrared LED lights, also known as infrared diodes or IR LEDs, are electronic devices that emit light in the infrared region of the electromagnetic spectrum. Unlike visible light, infrared light is not visible to the human eye but can be detected by specialized sensors and cameras. The infrared spectrum spans wavelengths from 700 nanometers to 1 millimeter, with different applications utilizing specific ranges within this spectrum.
The key to the functionality of an infrared LED light lies in its semiconductor material, typically gallium arsenide (GaAs) or indium gallium arsenide (InGaAs). When an electric current is applied to these materials, electrons are excited and recombine, emitting photons in the infrared range. The efficiency and intensity of the emitted light depend on the quality of the semiconductor material and the design of the LED.
