LED MANUFACTURE METHOD Russian patent published in 2016 - IPC H01L27/15 H01L33/00 

FIELD: electricity.

SUBSTANCE: semiconductor emitter and transparent light-outputting element are joined into the united emitting element, protective antireflective coating is applied to outer surface of the light-outputting element. The protective antireflective coating is made of material, which refraction index is $$\frac{n_C}{n_E}$$ times less than refraction index of the material used for the light-outputting element, where n_C is refraction index of the protective antireflective coating, n_E is refraction index of the material used for the light-outputting element. Thickness h_C of the protective antireflective coating is preset on conditions of transmission factor of the light-outputting element as per the formula where d₀ is optical thickness of the antireflective coating, n_C is refraction index of the protective antireflective coating.

EFFECT: simplified process of LED manufacture.
