Abstract
A variety of light-emitting devices are disclosed that are configured to output light provided by a light-emitting element (LEE). In general, embodiments of the light-emitting devices feature two or more light-emitting elements, a scattering element that is spaced apart from the light-emitting elements, an extractor element coupled to the scattering element, and a reflective element that is configured and arranged to reflect light emitted from the light-emitting elements.

1-30. (canceled)
A light-emitting device, comprising:
- a base substrate;
- a plurality of light-emitting elements (LEEs) disposed on the base substrate;
- a plurality of first optical elements, each first optical element of the plurality of first optical elements having a first surface spaced apart from the plurality of LEEs, positioned to receive light from one or more of the plurality of LEEs, and configured to scatter light passing therethrough;
- a plurality of second optical elements, each second optical element of the plurality of second optical elements having an exit surface, being transparent and optically coupled with a respective first optical element, and arranged to receive light therefrom;
- and
- one or more reflective elements disposed between LEEs of the plurality of LEEs, the one or more reflective elements having reflective surfaces arranged to reflect portions of light emitted from the plurality of LEEs, and wherein the one or more reflective elements separate adjacent second optical elements.
