the inside of the extractor element 130 adjacent an enclosure 140 e g a semispherical enclosure of radius r o of the extractor element 130 and form an optical interface 125 in some implementations the scattering element can be a layer e g coating with scattering centers in some implementations the scattering element can be a roughening of the inner surface of the extractor the enclosure 140 can be filled with a medium e g gas or air and encloses the light emitting elements 110 and 112 and at least a portion of the surface 155 the scattering element 120 can have a spherical hemi spherical or other shape such shapes can range from dome like via flat to bowl like shapes the scattering element can have one or more indentations an example light emitting device with a flat scattering element may have a substrate configured similarly to the one of the example light emitting device of fig2 c and 2d depending on the implementation the medium in the enclosure 140 can be a gaseous or other medium having a refractive index n 0 that is greater or equal to 1 and smaller or equal to a refractive index n 120 of the scattering element 120 1 u2266 n 0 u2266 n 120 or the medium can have a refractive index n 0 that is greater or equal to a refractive index n 120 of the scattering element 120 n 0 u2267 n 120 the refractive index of the medium in the enclosure 140 may have a refractive index comparable to the refractive indices of the light emitting elements for example the medium in the enclosure 140 surrounds the light emitting.
