+A **Light Diode** is a semiconductor device that emits light when an electric current flows through it. This elegant conversion of electrical energy into light occurs through the process of [electroluminescence](/wiki/electroluminescence). It stands as a foundational element in modern [Optoelectronics](/wiki/optoelectronics), illuminating our world from indicators to displays.
