Expert
An LED refers to the solid- state device consisting of forward –biased p-n junction transistor that is made from the slice or chip of the gallium arsenide phosphate (GaAsP) mounted in the transparent covering. When current flows through the chip it will emit the light that is in direct proportion to current flow. Light emission in several colors of the spectrum may be achieved by varying the proportions of elements consisting of the chip, and may also be attained by using technique known as doping with the other elements, for example. Nitrogen.
