A light-emitting diode (LED) is a semiconductor diode that emits incoherent narrow-spectrum lightwhen electrical current is applied in the forward direction.
An LED consists of several layers of semiconducting material
When an LED is operated with DC current, light is generated in the active layer
The generated light is radiated directly or by reflections
In contrast to incandescent lamps, which emit a continuous spectrum, an LED emits light in a certain color
The color of the light depends on the material used.
Different voltages between 2-4 V are necessary in order to operate diodes of different colors in conducting direction.
