LED with optical element
A light emitting structure includes one or more optical barriers which may have some gaps or discontinuity in order to decrease the amount of light absorbed by the optical barrier. The optical barrier may have a gap in the vertical direction between it and the substrate, or between it and the top of a side coat, or both. The optical barrier may have a gap or discontinuity in the horizontally direction, so that it does not fully surround the LED or phosphor horizontally. This may increase the light extraction efficiency of the light emitting structure.
