hundred and forty-six hundred and thirtieths 1.97eV, so power conversion efficiency of light energy n (E-L) =1.97/2.2x100% 90%, That is, 0.0.23eV of energy loss (EV electron volts).
If the LED of a GaN blue 470nm, VF 3.4V, so EB 3.4EeV, EB one thousand two hundred and forty-four hundred and seventieths 2.64eV, so Nb=2.64/3.4x100% 78%, this is assuming that when you Nint=100%. If Nint=60%, then for the red LED,N (E-L) =90%x60%=54%, and n for blue LED (E-L) B=78%x60%=47s%. Visible, t
