(about LED)
In the case of light-emitting diodes that convert electrical signals into light, what properties of light can be used? wave or particle???

I know that its not corresponding to photoelectric effect.
But Isn't the energy being released into the form of light a particle of light? i mean does light-emitting diodes use or can be explained by particle property of light???

    Experiment 11: Investigating Bandgap Energies, Materials, and Design of Light-Emitting Diodes (LED) 3. For a device to be a good conductor, there must be a significant electron population in the conduction band. When no energy is supplied to a semiconductor, the relative population of the conduction band follows Boltzmann's population law. In the case of a diode, the equation is: CB Population = e /RT VB Population Where CB and VB population are the respective electron populations in the conduc-...
