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 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 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 7-step MacAdam ellipse around any point on the black body locus having a correlated color temperature between about 3500K and about 6500K; 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 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 1800K, the constant CCT line of 1800K, and the spectral locus; 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.
