SOLID STATE LIGHTING DEVICES WITH COLOR POINT NON-COINCIDENT WITH BLACKBODY LOCUS

摘要

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.
