Abstract:
The present disclosure provides methods for generating white light. The methods use a plurality of LED strings to generate light with color points that fall within blue, yellow/green, red, and cyan color ranges, with each LED string being driven with a separately controllable drive current in order to tune the generated light output.

Claim (Index 2):
The method of  claim 1 , wherein:\n the light produced from the first LED string is passed through a first recipient luminophoric medium that comprises a first luminescent material, wherein light exiting the first luminophoric medium comprises unsaturated light having a first color point within a blue color range defined by a line connecting the ccx, ccy color coordinates of the infinity point of the Planckian locus (0.242, 0.24) and (0.12, 0.068), the Planckian locus from 4000K and infinite CCT, the constant CCT line of 4000K, the line of purples, and the spectral locus; the light produced from the second LED string is passed through a second recipient luminophoric medium that comprises a second luminescent material, wherein the light exiting the second luminophoric medium comprises unsaturated light having a second color point within a red color range defined by the spectral locus between the constant CCT line of 1600K and the line of purples, the line of purples, a line connecting the ccx, ccy color coordinates (0.61, 0.21) and (0.47, 0.28), and the constant CCT line of 1600K; the light produced from the third LED string is passed through a third recipient luminophoric medium that comprises a third luminescent material, wherein the light exiting the third luminophoric medium comprises unsaturated light having a third color point within a yellow/green color range defined by the constant CCT line of 4600K, the Planckian locus between 4600K and 550K, the spectral locus, and a line connecting the ccx, ccy color coordinates (0.445, 0.555) and (0.38, 0.505); the light produced from the fourth LED string is passed through a fourth recipient luminophoric medium that comprises a fourth luminescent material, wherein the light exiting the fourth luminophoric medium comprises unsaturated light having a fourth color point within a cyan color range defined by a line connecting the ccx, ccy color coordinates (0.18, 0.55) and (0.27, 0.72), the constant CCT line of 9000K, the Planckian locus between 9000K and 4600K, the constant CCT line of 4600K, and the spectral locus.
