Introduction to IR LED 880 nm

What is an IR LED 880 nm?

An IR LED 880 nm, also known as an infrared light-emitting diode with a peak emission wavelength of 880 nanometers, is a type of electronic component that emits infrared light. It is widely used in various applications, such as remote controls, communication systems, and medical devices. The 880 nm wavelength falls within the near-infrared region of the electromagnetic spectrum, which is invisible to the human eye but can be detected by certain sensors and devices.

Working Principle of IR LED 880 nm

The working principle of an IR LED 880 nm is based on the photoelectric effect. When a forward voltage is applied to the diode, electrons and holes are injected into the active region, where they recombine and release energy in the form of photons. The wavelength of the emitted light depends on the energy gap between the valence band and the conduction band of the semiconductor material used in the diode. In the case of an IR LED 880 nm, the semiconductor material typically used is aluminum gallium indium phosphide (AlGaInP).
