Introduction to IR LED NM: The World of Infrared Light Emitting Diodes

What is IR LED NM?

Infrared Light Emitting Diodes (IR LEDs) are semiconductor devices that emit infrared light when an electric current passes through them. The term "IR LED NM" refers to the specific wavelength of the infrared light emitted by these diodes, which is measured in nanometers (nm). The "NM" in IR LED NM stands for "nanometers," indicating the precise range of wavelengths that these LEDs produce. This article aims to provide an in-depth introduction to the world of IR LED NM, exploring their applications, advantages, and the industry trends surrounding them.

How Do IR LEDs Work?

IR LEDs work on the principle of the semiconductor junction. When an electric current is applied to the junction, electrons and holes are created. As these electrons recombine with the holes, they release energy in the form of photons. In the case of IR LEDs, these photons have wavelengths within the infrared spectrum, which is not visible to the human eye. The specific wavelength of the emitted light depends on the composition of the semiconductor material used in the LED.
