Claim Text:
1. A lighting device comprising: at least one electrically activated solid state emitter; at least one lumiphoric material spatially segregated from the at least one electrically activated solid state emitter, and arranged to receive at least a portion of emissions from the at least one electrically activated solid state emitter; and at least one optical element, including at least one of an optical filter and an optical reflector, arranged between the at least one electrically activated solid state emitter and the at least one lumiphoric material, wherein the at least one optical element comprises an inner face proximate to the at least one electrically activated solid state emitter, an outer face distal from the at least one electrically activated solid state emitter, and at least one peripheral edge bounding the inner face and the outer face; wherein at least a portion of the inner face includes a cross-sectional shape that is curved or non-planar, at least a portion of the outer face includes a cross-sectional shape that is curved or non-planar, the at least a portion of the inner face is arranged to transmit at least a portion of emissions from the at least one electrically activated solid state emitter to impinge on the at least one lumiphoric material, and at least a portion of the outer face is arranged to transmit at least a portion of emissions from the at least one electrically activated solid state emitter to impinge on the at least one lumiphoric material.
