Abstract:
A lighting device includes at least one first electrically activated emitter, at least one lumiphor support element comprising a lumiphoric material spatially segregated from the first electrically activated emitter and arranged to receive at least a portion of emissions from the first electrically activated emitter, and at least one second electrically activated emitter disposed on or adjacent to the at least one lumiphor support element. First and second electrically activated emitters having different peak wavelengths may be in conductive with first and second device-scale heat sinks, respectively.
