What is an Infrared LED 5mm?

An

Infrared LED 5mm

is a type of light-emitting diode (LED) that emits infrared light at a wavelength of approximately 850 to 940 nanometers. The "5mm" refers to the diameter of the LED's lens, which is a standard size for many optoelectronic devices. Unlike visible light LEDs, infrared LEDs emit light that is not visible to the human eye, making them ideal for applications where covert or invisible communication is required.

How Does an Infrared LED 5mm Work?

The operation of an

Infrared LED 5mm

is based on the principles of electroluminescence. When an electric current is applied to the LED, electrons recombine with electron holes within the semiconductor material, releasing energy in the form of photons. In the case of an infrared LED, these photons have wavelengths that fall within the infrared spectrum, making them invisible to the naked eye.
