LED Thecnology

 

Light Emitting Diode.

 

LED stands for Light Emitting Diode. This is a semiconductor device emiting monocromatic light when a voltage is applied so an electrical current flows in it. Light color depends on the semiconductor compound going from ultraviolet to infrared, and all over the human visible spectrum.

The semiconductor device is commonly encapsulated in a plastic cover for increased resistance to the glass that is usually used in light bulbs. Although the plastic can be colored just for aesthetic reasons as it would not affect the color of the light emitted.

The first LED that emitted in the visible spectrum was developed by General Electric engineer, Nick Holonyak in 1962. Today, the main advantages of LED lamps are long life, high robustness and high efficiency light

The rapid evolution of this technology has enabled the creation of large-format screens for outside, opening great opportunities for viewing all kinds of information.
