LED diode. How does LED lighting work?
The operation of LED lighting is based on electroluminescence, which is the result of a combination of electrons and holes in the P-N semiconductor connectors found in LED diodes.
Semiconductor is a crystal that is made of two layers – the N layer contains electrons (negative charge) while the P layer contains so-called holes (positive charge). When the current is supplied to the semiconductor, the electrons from the N layer jump to the P layer and during this jump, the energy separated out in the form of radiation – that is, simply light – is released. In contrast to incandescent bulbs and so-called energy-saving fluorescent lamps, there is no energy loss for heat and no harmful substances for the environment. In addition, LED bulbs are 100% biodegradable.
