Beschreibung
Zusammenfassung:	A luminaire includes an excitation light source which emits excitation light. A first fluorescent plate includes a first principle surface disposed across the optical axis of the excitation light. A first phosphor layer is arranged discretely along the first principle surface. A second fluorescent plate is arranged at the downstream side of the excitation light with respect to the first fluorescent plate. The second fluorescent plate includes a second principle surface disposed across the optical axis. A second phosphor layer is arranged discretely along the second principle surface. The second phosphor layer has a wavelength conversion characteristic different from a wavelength conversion characteristic of the first phosphor layer. A support supports the first fluorescent plate and the second fluorescent plate such that at least one of relative positions and rotations of the first fluorescent plate and the second fluorescent plate are adjustable.
