LIGHTING DEVICE AND LIGHTING METHOD

摘要

A lighting device comprising one or more solid state light emitters which emit near ultraviolet light and one or more lumiphors which emit light having a wavelength in the range of from 490 nm to 555 run, which in the absence of other light would produce a mixture of light within an area defined by x, y 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 a mixture of light emitted from the lighting device may be within ten Mac Adam ellipses of the blackbody locus. Also, packaged solid state light emitters and methods of lighting.
