Abstract:
A solid state lighting device includes at least one electrically activated solid state light emitter configured to stimulate emissions of first through third lumiphoric materials having peak wavelengths in ranges of from 485 nm to 530 nm, from 575 nm to 595 nm, and from 605 nm to 640 nm, respectively (or subranges thereof defined herein), with the third peak having a full width half maximum value of less than 60 nm. The resulting device generates aggregated emissions having a suitably high color rendering index (e.g., CRI Ra) value (e.g., at least 70), and also having a spectral power distribution with a Melanopic/Photopic ratio within a specified target range as a function of correlated color temperature, thereby providing increased perceived brightness.

Claim (Index 1):
A lighting device comprising:\n at least one electrically activated solid state light emitter arranged to generate emissions having a peak wavelength in a blue range; and first through third lumiphoric materials arranged to receive at least a portion of emissions of the at least one electrically activated solid state light emitter and configured to responsively generate lumiphor emissions; wherein:\n lumiphor emissions of the first lumiphoric material have a first peak wavelength in a range of from 485 nm to 530 nm; \n lumiphor emissions of the second lumiphoric material have a second peak wavelength in a range of from 575 nm to 612 nm; \n lumiphor emissions of the third lumiphoric material having a third peak wavelength in a range of from 605 nm to 640 nm, wherein the third peak wavelength corresponds to a third peak having a full width half maximum value of less than 60 nm; \n the lighting device is configured to produce aggregated emissions including emissions of the at least one electrically activated solid state light emitter, the first lumiphoric material, the second lumiphoric material, and the third lumiphoric material; \n the lighting device is configured to produce aggregated emissions having a CRI Ra value of at least 70; and \n the lighting device is configured to produce aggregated emissions having a spectral power distribution with a Melanopic/Photopic ratio (M/P ratio) value within a target range as a function of correlated color temperature (CCT) in Kelvin of the aggregated emissions, the target range including minimum values defined by a minimum value function in which M/P ratio equals [\u22122.05\u00d710 \u22128 (CCT) 2 +2.72\u00d710 \u22124 (CCT)\u22120.1506], and the target range including maximum values defined by a maximum value function in which M/P ratio equals [\u22122.57\u00d710 \u22128 (CCT) 2 +3.70\u00d710 \u22124 (CCT)\u22120.1889], and CCT being in a range of from 2000 to 7000 Kelvin.
