A light-emitting diode (LED) is a semiconductor device that emits visible light
when an electric current passes through it.
Introduction: The LED is a light source which uses semiconductors and
electroluminescence to create light. There are two major kinds of light emitting
The positive side of the LED is called the “anode” and is marked by having a
longer “lead,” or leg. The other, negative side of the LED is called the “cathode.
But, even better, there are LEDs (light-emitting diodes) that are just as bright as
bulbs, last virtually forever, and use hardly any energy at all. An LED is a special
