Abstract
Solid state light emitting devices include lumiphor elements that are spatially segregated from electrically activated solid state emitters with an intermediately arranged optical element (including but not limited to a dichroic filter). Curved or faceted optical elements, and curved or faceted reflectors, may be employed. Multiple solid state emitters may be arranged in multiple reflector cups or recesses. Characteristics of optical elements and/or lumiphor elements of such devices may be varied with respect to angular position.
