Introduction to IR LED nm Technology

What is IR LED nm?

In the realm of optoelectronics, the term "IR LED nm" refers to infrared light-emitting diodes (LEDs) that emit light at a specific nanometer (nm) wavelength. These LEDs are a crucial component in various applications, including remote controls, surveillance systems, medical devices, and automotive sensors. The "nm" in IR LED nm denotes the wavelength of the emitted light, which typically ranges from 780 to 1000 nm, placing it in the near-infrared spectrum.

Working Principle of IR LED nm

The operation of an IR LED nm is based on the principle of electroluminescence. When an electric current is applied to the semiconductor material within the LED, it excites electrons, causing them to recombine with electron holes. This recombination process releases energy in the form of photons, which are emitted as infrared light. The specific wavelength of the emitted light is determined by the energy bandgap of the semiconductor material used in the LED.
