What is a 940nm Infrared LED?

A 940nm infrared LED is a type of infrared LED that emits light at a wavelength of 940 nanometers. This wavelength falls within the near-infrared range, which is just beyond the visible spectrum for humans. The 940nm infrared LED is known for its high efficiency and long wavelength, making it ideal for applications that require long-range detection and low visibility.

How Does a 940nm Infrared LED Work?

The functioning of a 940nm infrared LED is based on the principle of electroluminescence. When an electric current is applied to the semiconductor material within the LED, electrons and holes are excited and recombine, releasing energy in the form of photons. These photons are emitted as infrared light with a wavelength of 940nm. The semiconductor material used in 940nm infrared LEDs is typically a combination of gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs).
