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 21):
A semiconductor light emitting device, comprising:\n a first light emitting diode (\u201cLED\u201d) string that comprises a first LED that has a first recipient luminophoric medium that comprises a first luminescent material, wherein the first LED and first luminophoric medium together emit a first unsaturated light having 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); a second LED string that comprises a second LED that has a second recipient luminophoric medium that comprises a second luminescent material, wherein the second LED and second luminophoric medium together emit a second 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; a third LED string that comprises a third LED that has a third recipient luminophoric medium that comprises a third luminescent material, wherein the third LED and third luminophoric medium together emit a third unsaturated light having 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 a drive circuit; wherein the drive circuit is configured to adjust the relative values of first, second, third, and fourth drive currents provided to the LEDs in the first, second, and third LED strings, respectively, to adjust a fourth color point of a fourth unsaturated light that results from a combination of the first, second, and third unsaturated light.
