Abstract
A variety of light-emitting devices for general illumination utilizing solid state light sources (e.g., light-emitting diodes) are disclosed. A light-emitting device can include a first light-emitting element (LEE) for emitting light having a first spectral composition, a second LEE for emitting light having a second spectral composition, and a scattering element surrounding at least in part the first and second LEEs to scatter light emitted from the first and second LEEs. The light-emitting device can also include electrical connections for connecting the first and second LEEs to a power source, where the electrical connections are arranged such that power to the first LEE is separately adjustable relative to power to the second LEE.

36. A light-emitting device, comprising:
-
a substrate having a first surface; two or more light-emitting elements (LEEs) disposed on the first surface; and a scattering element surrounding, at least in part, the two or more LEEs, the scattering element comprising inelastic scattering centers arranged to scatter light from the two or more LEEs, wherein the scattering element includes a plurality of segments, each of the segments configured to provide light having one of two or more spectral compositions; and electrical connections for connecting the two or more LEEs to a power source, the electrical connections being arranged such that power to at least one first LEE of the two or more LEEs is separately adjustable relative to power to at least one second LEE of the two or more LEEs. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62)
