Beschreibung
Zusammenfassung:	A lighting device comprising plural excitation sources configured to provide at least two excitation peak emissions of different wavelength and at least one phosphor material radiationally coupled to the plural light source, the lighting device having a plurality of operational states comprising a first operation state wherein excitation of the at least one phosphor material by a first peak emission from the plural excitation sources provides a first correlated color temperature (CCT) value, and at least one additional operational state wherein excitation of the at least one phosphor material by a second peak emission from the plural excitation sources provides at least one additional CCT value different from the first CCT value. Methods of varying the CCT value using the lighting device with controlled power distribution to the plural excitation sources.
