Working Principle of Infrared IR LED

The infrared IR LED operates on the principle of the semiconductor diode. When a forward voltage is applied across the diode, electrons and holes recombine at the junction, releasing energy in the form of light. In the case of an infrared IR LED, the emitted light falls within the infrared spectrum, which is not visible to the human eye. The wavelength of infrared light typically ranges from 700 nm to 1 mm, with different types of IR LEDs emitting light at specific wavelengths. The key components of an infrared IR LED include the semiconductor material, a p-n junction, and a reflector. The semiconductor material is chosen based on the desired wavelength of the emitted light. Common materials used in infrared IR LEDs include gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs). The p-n junction creates a region where electrons and holes recombine, and the reflector helps to concentrate the emitted light in the desired direction.
