What is a 12V IR LED?

A 12V IR LED, or Infrared Light Emitting Diode, is a type of semiconductor device that emits infrared radiation when an electric current passes through it. The "12V" refers to the voltage required to operate the LED efficiently. These LEDs are designed to emit light in the infrared spectrum, which is not visible to the human eye but can be detected by infrared sensors and cameras.

Working Principles of 12V IR LEDs

The operation of a 12V IR LED is based on the principle of the PN junction. When a forward voltage is applied across the diode, electrons and holes are injected into the depletion region. As these charge carriers recombine, they release energy in the form of photons. In the case of IR LEDs, the energy released falls within the infrared spectrum, making them ideal for applications that require invisible light.
