Abstract:
Solid state lighting devices include at least one electrically activated solid state light emitter and at least one lumiphor (or multiple electrically activated emitters optionally devoid of a lumiphor), with resulting emissions arranged to attain a color point in a desired CCT range (e.g., from 2,500K to 10,000K) that is non-coincident with a blackbody or Planckian locus, preferably with a negative Planckian offset Delta u′v′ value (below the Planckian locus) according to a CIE 1976 chromaticity diagram, such as a value in a range of no greater than negative 0.01.
