Abstract
A light emitting device includes a light emitting diode configured to emit blue or ultraviolet radiation incident photons, a color conversion material located over the light emitting diode and configured to absorb the incident photons emitted by the light emitting diode and to generate converted photons having a longer peak wavelength than a peak wavelength of the incident photons, and at least one light extracting feature located between the light emitting diode and the color conversion material.
