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. |
