What does the acronym LED stand for?

The acronym LED stands for Light Emitting Diode. This technology refers to a semiconductor device that emits light when an electric current passes through it. The principle behind an LED’s operation is electroluminescence, which occurs when electrons recombine with holes within the device, releasing energy in the form of photons, or light.

This definition is significant in the context of various applications, such as lighting, displays, and indicators, due to the advantages LEDs offer, such as energy efficiency, long lifespan, and reduced heat output compared to traditional incandescent bulbs. Understanding this terminology is essential for grasping the fundamental concepts of electronic components and their applications in contemporary technology.
