ABSTRACT:
A lighting device comprising two or more solid state light emitters which emit light in the range of 430 nm to 480 nm and one or more lumiphors which emit light in the range of 555 nm to 585 nm. Also, a lighting device comprising two or more solid state light emitters. The lighting devices make a mixture of light which in the absence of any other light would be within an area defined by coordinates (0.32, 0.40), (0.36, 0.48), (0.43, 0.45), (0.42, 0.42), and (0.36, 0.38). The lighting device may further comprise one or more 600 nm to 630 nm light emitters, and the lighting device may emit light within ten MacAdam ellipses of the blackbody locus. Also, packaged solid state light emitters and methods of lighting.
