LED Lighting Basics

August 16, 2013 - 10:07am


Light-Emitting diodes (LEDs) efficiently produce light in a fundamentally different way than any legacy or traditional source of light.  LEDs are compound semiconductor devices that produce light when an appropriate electrical current is applied.  Applying electrical current causes electrons to flow from the positive side of a diode structure to the negative side causing a chain of complex interactions at an atomic level that releases light in a very efficient, predictable and orderly way.

LEDs are often used as small indicator lights on various electronic devices. Because of their long life, durability, and efficiency, LEDs are becoming more common in residential, commercial, and outdoor area lighting applications.
