2012 Infrared LED: Innovations & Applications Unveiled

Introduction to 2012 Infrared LED Technology

What is an Infrared LED?

An infrared LED, or Light Emitting Diode, is a type of semiconductor device that emits infrared light when an electric current is applied. Unlike visible light LEDs, which emit light that is visible to the human eye, infrared LEDs emit light at wavelengths beyond the visible spectrum, typically between 700 nanometers (nm) and 1,000 nm. This makes them ideal for various applications where invisible light is required, such as remote controls, communication, and security systems.

2012 Infrared LED Technology

The year 2012 marked a significant milestone in the development of infrared LED technology.
