PPT-Using light emitting diodes for lighting

By Grant Gorman and alec pahl 562013 Abstract Light emitting diodes are semiconductor devices that emit light when a voltage is places across them They have become increasingly popular in lighting applications because of their high efficiency and long lasting output . ELE 432 Assignment # 3 Vijay Kumar Peddinti Light Emitting Diodes Principle The first known report of a light-emitting solid-state diode was made in 1907 by the British experimenter H. J. Round.
