What is an Infrared LED 5mm?

An infrared LED 5mm, also known as an IR LED, is a type of light-emitting diode that emits infrared radiation at a wavelength of approximately 850nm. These diodes are widely used in applications that require invisible light for communication, detection, and sensing purposes. The 5mm size refers to the diameter of the LED, making it compact and suitable for integration into various devices. Infrared LEDs work on the principle of forward biasing, where a voltage is applied across the diode, causing electrons to recombine with holes, releasing energy in the form of photons. The emitted photons have a longer wavelength than visible light, making them invisible to the human eye. This characteristic makes infrared LEDs ideal for applications where visibility is not desirable, such as in security systems or remote controls.
