is for LED




Light-emitting diodes (LEDs) are semiconducter light sources with many different uses. They have been very popular as indicator lights in electronic circuits and have found many other uses for lighting things such as TV screens. They have a very long life, use very little energy and produce very low levels of heat compared to other options. They are a popular choice for the output of a circuit when teaching electronics in schools along  with DC motors.
