Question:ningcuidi
photon energy, then ask: all of these photons can escape into the air see? answer is no. So there will be a LED photon emission rate of problems. Can be represented this way LED in the ratio of photons to escape into the air.
Nout= (escape into the air at the photon number/PN knot have a total number of photons) x100%
In the above formula, we can be LED quantum efficiency. To facilitate the description, we assume that LED material as GaAs, the material refraction coefficient for N1=3
