equired associated with LED the band at different wavelengths are different. Photon energy e is different at different wavelengths, transforms the inevitable loss of power to light, as an example to illustrate:
For example, an in D=630nm GaInAlP four-Orange LED, its to the bias as VF 2.2V, so means it's an electron and a hole-electron potential energy required to composite into a carrier of ER=2.2Ev, and one to the potential energy of the photon as a E=Hc/of D=630nm to d one thousand two
