ABSTRACT
For an understanding of what a light emitting diode is, perhaps a is needed. Grant you, what I offer here is a very elementary explanation. At this time, for both the student and beginning SM, it is not important to know the absolute technical details, but rather to have a general knowledge when speaking of a diode or LED lights, for surely the terms will be part of lighting conversations that an SM has with stage technicians:
A diode is a very small, square-shaped or dome-shaped solid piece of plastic-like material made up of a mixture of chemical elements. Incased within this treated plastic is a positive and negative conductor that, when submitted to an electric current, reacts with the chemical of the diode and emits light of a particular color.
