摘要:
A lighting device comprising a first group of solid state light emitters, with peak wavelength from 430 nm to 480 nm, and optionally a second group with dominant wavelength from 600 nm to 630 nm, and a first group of lumiphors which emit light having dominant wavelength from 555 nm to 585 nm. In some embodiments, if current is supplied to a power line, a combination of (1) light exiting the lighting device which was emitted by the first group of emitters, and (2) light exiting the lighting device which was emitted by the first group of lumiphors would, in an absence of any additional light, produce a sub-mixture of light having x, y color coordinates within an area on a 1931 CIE Chromaticity Diagram defined by points having coordinates (0.32, 0.40), (0.36, 0.48), (0.43, 0.45), (0.42, 0.42), (0.36, 0.38). Also provided is a method of lighting.
