What does the acronym LED stand for?

The acronym LED stands for Light Emitting Diode. This term describes a specific type of semiconductor device that emits light when an electric current passes through it. The operation of an LED is based on electroluminescence, which is the emission of light from a material when it is electrically energized. The diode aspect refers to its ability to allow current to flow in one direction, making it efficient for various applications in lighting, displays, and indicators. Understanding this term is essential in various fields, including electronics and beauty technology, where LED usage has become prevalent for lighting and effects in treatments.
