Lighting device comprising LEDs with phosphor layers
A lighting device comprising LEDs with phosphor layers includes a plurality of LED sets which can emit light with a peak emission wavelength between 360 nm and 490 nm; and a plurality of sets of phosphor layers covering the corresponding LED sets among the plurality of LED sets. At least two of the plurality of LED sets respectively have peak emission wavelength different from each other. The dominant fluorescence wavelength of at least one of the plurality of sets of phosphor layers ranges from 500 nm to 580 nm, and the dominant fluorescence wavelength of at least one of the other sets of phosphor layers ranges from 590 nm to 650 nm.
