A lighting device comprising: a plurality of electrically activated emitters (521A, 521B, 521C, 522, 523) including at least one first electrically activated emitter having a first peak wavelength, and at least one second electrically activated emitter (522, 523) having a second peak wavelength, wherein each of said first and second peak wavelength differs from one another; a first lumiphor spatially segregated from and arranged to receive emissions from the at least one first electrically activated emitter; a first emitter support element arranged to support the at least one first electrically activated emitter; a second emitter support element arranged to support the at least one second electrically activated emitter (522, 523), wherein the second emitter support element is spatially segregated from, and/or is in insubstantial thermally conductive communication with, the first emitter support element; an optical filter arranged between the at least one first electrically activated emitter and the first lumiphor; and at least one of (i) a single reflector and (ii) a single diffuser, arranged to receive at least some emissions from each emitter of the plurality of electrically activated emitters (521A, 521 B, 521C, 522, 523); wherein at least a portion of the second emitter support element is arranged non-coplanar with the first emitter support element, at least a portion of the second emitter support element comprises a material that is substantially transmissive of the first peak wavelength, and at least a portion of the second emitter support element is arranged to permit transmission of at least a portion of emissions of the at least one first electrically activated emitter toward an emissive end of the lighting device. a plurality of electrically activated emitters (521A, 521B, 521C, 522, 523) including at least one first electrically activated emitter having a first peak wavelength, and at least one second electrically activated emitter (522, 523) having a second peak wavelength, wherein each of said first and second peak wavelength differs from one another; a first lumiphor spatially segregated from and arranged to receive emissions from the at least one first electrically activated emitter; a first emitter support element arranged to support the at least one first electrically activated emitter; a second emitter support element arranged to support the at least one second electrically activated emitter (522, 523), wherein the second emitter support element is spatially segregated from, and/or is in insubstantial thermally conductive communication with, the first emitter support element; an optical filter arranged between the at least one first electrically activated emitter and the first lumiphor; and at least one of (i) a single reflector and (ii) a single diffuser, arranged to receive at least some emissions from each emitter of the plurality of electrically activated emitters (521A, 521 B, 521C, 522, 523); wherein at least a portion of the second emitter support element is arranged non-coplanar with the first emitter support element, at least a portion of the second emitter support element comprises a material that is substantially transmissive of the first peak wavelength, and at least a portion of the second emitter support element is arranged to permit transmission of at least a portion of emissions of the at least one first electrically activated emitter toward an emissive end of the lighting device.
