Question:ningcuidi
not to say, LED light conversion efficiency reached 100%? the answer is no.
From semiconductor theory can know, because different materials and epitaxial growth process of different, made from LED light wavelengths are different. Assuming the LED quantum efficiency of different light wavelengths are at 100%, but due to an electronic n-type layer and a motion to PN junction active a hole from the p-type layer movement to the active layers in PN junctions, energy e of a composite carriers r
