LIGHTING DEVICE WITH DEFINED SPECTRAL POWER DISTRIBUTION

摘要

Solid state lighting devices and illumination methods involve use of multiple solid state emitters of different colored outputs (optionally including at least one white or near-white emitter). Operation of the solid state emitters is controlled with at least one circuit element to emphasize and/or deemphasize perception of at least one color of a target surface based upon a reflectance spectral distribution of the target surface. At least one emitter may have an associated passive or active filter; the filterable emitter and/or active filter may be operated to deemphasize perception of at least one color of a target surface. Activation and/or alteration of emphasis or deemphasis of perception of color of a target surface may be selected by a user or automatically controlled.
