What is a LED?



A light emitting diode, abbreviated as DEL or LED abbreviations (In English , Light Emitting Diode), is a component capable of emitting light when traversed by electric current.

We know these electronic components historically from their use as indicator lights on remote controls, electronics, and televisions. 
It was in 1993 that the LED "white" made its appearance , after research in lighting permitted tremendous development . Today there are several methods to create white light, the most common being that combines   the use of LEDs emitting in the blue with a phosphor layer which converts it to white light. The composition of the phosphor is used to produce specific wavelengths, and providing quality white and various colors
