Introduction to Infrared Transmitting LEDs

Infrared transmitting LEDs, also known as infrared diodes, are semiconductor devices that emit infrared light when an electric current passes through them. They are widely used in various fields due to their advantages such as high efficiency, low power consumption, and stable performance. The main materials used to manufacture infrared transmitting LEDs are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium arsenide (InGaAs).

Working Principles of Infrared Transmitting LEDs

The working principle of infrared transmitting LEDs is based on the photoelectric effect. When an electric current is applied to the diode, electrons and holes are generated in the semiconductor material. When these electrons and holes recombine, they release energy in the form of photons. The energy of these photons determines the wavelength of the emitted light. In the case of infrared transmitting LEDs, the photons have a wavelength between 700 nm and 3000 nm, which falls within the infrared spectrum.
