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

Claim (Index 1):
A method of generating white light, the method comprising:\n producing light from a first light emitting diode (\u201cLED\u201d) string that comprises a blue LED with a peak wavelength of between about 405 nm and about 470 nm; producing light from a second light emitting diode (\u201cLED\u201d) string that comprises a blue LED with a peak wavelength of between about 405 nm and about 470 nm; producing light from a third light emitting diode (\u201cLED\u201d) string that comprises a blue LED with a peak wavelength of between about 405 nm and about 470 nm; passing the light produced by each of the first, second, and third LED strings through one of a plurality of respective luminophoric mediums to produce a first unsaturated light, a second unsaturated light, and a third unsaturated light, respectively; combining the first unsaturated light, the second unsaturated light, and the third unsaturated light together into a fourth unsaturated light; wherein the first unsaturated light has a first color point within a white color range defined by a polygonal region on the 1931 CIE Chromaticity Diagram defined by the following ccx, ccy color coordinates: (0.4006, 0.4044), (0.3736, 0.3874), (0.3670, 0.3578), (0.3898, 0.3716); wherein the second unsaturated light has 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; wherein the third unsaturated light has 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); and wherein fourth unsaturated light corresponds to at least one of a plurality of points along a predefined path near the black body locus in the 1931 CIE Chromaticity Diagram within a 7-step MacAdam ellipse around any point on the black body locus having a correlated color temperature between about 1800K and about 3200K.
