    摘要: A lighting device comprising first, second and third groups of solid state light emitters, the first group emitting light having a dominant wavelength of 430 to 490 nm, the second group at 525 to 575 (in some devices 540 to 575 nm), the third group at 610 to 640 nm. In some devices, wavelength of light from emitters in first and second groups, and light from second and third groups, differs by at least 70 nm. Some devices emit light having CRI Ra of at least 70 when first, second and third groups of emitters are illuminated. Also, a lighting arrangement comprising first, second and third groups as above, in addition to a fourth emitter emitting light of dominant wavelength outside the ranges for the first, second and third groups, and not more than 10 nm different from a dominant wavelength of a color on an item to be illuminated.
