A mixture of light emitted from the first group of emitters and the first group of lumiphors has x,y color coordinates within an area defined by coordinates (0.36,0.48), (0.43,0.45), (0.5125,0.4866), and (0.4087,0.5896) (or (0.41,0.455), (0.36,0.48), (0.4087,0.5896), and (0.4788,0.5202)). A mixture of light emitted from the second group of emitters and the second group of lumiphors is within an area defined by (0.32,0.40), (0.36,0.38), (0.30,0.26), and (0.25,0.29). A mixture of light from the first and second groups of emitters and the first and second groups of lumiphors is within an area defined by (0.32,0.40), (0.36,0.48), (0.43,0.45), (0.42,0.42), and (0.36,0.38) (or (0.32,0.40), (0.36,0.38), (0.41,0.455), and (0.36,0.48)). A mixture of light from all of these emitters and lumiphors is within ten MacAdam ellipses of the blackbody locus. Also, methods of lighting.
(A) mixing light from a first group of at least one solid state light emitter, light from a second group of at least one solid state light emitter, light from a third group of at least one solid state light emitter, light from a first group of at least one lumiphor and light from a second group of at least one lumiphor to form first group-second group-third group mixed illumination, where:
a mixture of light emitted from the first group of solid state light emitters and the first group of lumiphors would, in the absence of any additional light, have a first group mixed illumination having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram defined (as detailed below) by a set of points having x, y coordinates of (0.36, 0.48), (0.43, 0.45), (0.5125, 0.4866), and (0.4087, 0.5896); a mixture of light emitted from the second group of solid state light emitters and the second group of lumiphors would, in the absence of any additional light, have a second group mixed illumination having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram defined by a set of points having x, y coordinates of (0.32, 0.40), (0.36, 0.38), (0.30, 0.26), and (0.25, 0.29); a mixture of light emitted from the first group of solid state light emitters, the second group of solid state light emitters, the first group of lumiphors and the second group of lumiphors would, in the absence of any additional light, have a first group-second group mixed illumination having x, y color coordinates which define a point which is within an area on a 1931 CIE Chromaticity Diagram defined by a set of points having x, y coordinates of (0.32, 0.40), (0.36, 0.48), (0.43, 0.45), (0.42, 0.42), and (0.36, 0.38); and the first group-second group-third group mixed illumination having x, y coordinates on a 1931 CIE Chromaticity Diagram which define a point which is within ten MacAdam ellipses (and in some embodiments, within seven MacAdam ellipses) of at least one point on the blackbody locus on a 1931 CIE Chromaticity Diagram; or (B) mixing light from a first group of at least one solid state light emitter, light from a second group of at least one solid state light emitter, light from a third group of at least one solid state light emitter, light from a first group of at least one lumiphor and light from a second group of at least one lumiphor to form first group-second group-third group mixed illumination, where:
The solid state light emitters can be positioned, grouped and/or packaged in any desired way, a wide variety of which are possible. For instance, each solid state light emitter can be positioned separately, optionally contained in a package (e.g., in the form of packaged LEDs), or one or more elements each having a plurality of solid state light emitters can be provided (e.g., in the form of a plurality of solid state light emitters contained in a single package, such as those described in U.S. Patent Application No. 60/808,702, filed on May 26, 2006, entitled �Lighting Device� (inventors: Gerald H. Negley and Antony Paul van de Ven; attorney docket number 931�009 PRO) and U.S. patent application Ser. No. 11/751,982, filed May 22, 2007, the entireties of which are hereby incorporated by reference). For example, the device can include a first package which comprises at least five of the first group of solid state light emitters and at least five of the second group of solid state light emitters (in such a device, (1) each of the solid state light emitters in the first package can be separately addressable, or (2) each of the five solid state light emitters of the first group contained in the first package can be addressable as a series/parallel array, and each of the five solid state light emitters of the first group contained in the first package is addressable as a series/parallel array, the expression �series/parallel� array including but not limited to arrangements in which there are provided a plurality of subsets of emitters, the subsets being electrically connected in series, each subset including a plurality of emitters electrically connected in parallel.
