Claim 0:
1. A lighting device for generating a mixed white light with controllable spectral characteristics, the lighting device comprising:
a first light source configured to produce a first white light quantitatively characterized by a first set of spectral characteristics in which at least one of an oversaturated color spectrum and color gamut is prioritized over other characteristics;
a second light source configured to produce a second white light quantitatively characterized by a second set of spectral characteristics in which at least one of color rendering and color fidelity is prioritized over other characteristics;
a third light source configured to produce a third white light quantitatively characterized by a third set of spectral characteristics in which energy efficiency is prioritized over other characteristics; and
control electronics configured to control proportional contributions of the first light source, the second light source, and the third light source to the mixed white light such that the resultant mixed white light is variable by a user in a spectral light parameter space.
