Methods For Generating Melatonin-Response-Tuned White Light With High Color Rendering

A method of generating white light, the method comprising:

• producing light from a first light emitting diode (“LED”) string;
• producing light from a second LED string;
• producing light from a third LED string, a fourth LED string, or both the third LED string and the fourth LED string;
• and
• passing the light produced by each of the first, second, third, and fourth LED strings through one of a plurality of respective luminophoric mediums;
• combining the light exiting the plurality of respective luminophoric mediums together into white light;
• wherein the combined white 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;
• wherein one or more of the first, second, third, and fourth LED strings comprises a ultraviolet or violet LED having a peak wavelength of between about 360 nm and about 430 nm.
