The acronym LED stands for light-emitting diodes. LED is a semiconductor (electronic component) that will emit light radiation when an electric current pass.
LEDs have been used in our home and car appliances for about 40 years.
There is no filament or gas used, only chemical elements. In addition, LEDs do not contain polluting gases, heavy metals (such as mercury), and do not emit electromagnetic radiation.
LEDs do not emit any UV or infrared rays. They are very insensitive to vibrations, insensitive to repeated ignitions and low temperatures, have a long life and are energy efficient.
They emit 100% of their output as soon as they are switched on and more than 80% of the energy absorbed is returned in the form of light radiation.
