Embodiment Construction
[0016] figure 1 It is a cross-sectional view of a color-tunable lighting device 100 according to the first embodiment of the present invention, which includes an LED light source 20 and a fluorescent sheet 10 , and the fluorescent sheet 10 is movably arranged above the LED light source 20 . This movement refers to that the fluorescent sheet 10 is rotatable relative to the LED light source 20 (such as figure 1 shown), may also mean that the fluorescent sheet 20 moves in parallel relative to the LED light source 20 . The thickness of the fluorescent sheet 10 changes according to a predetermined rule in the moving direction of the fluorescent sheet 10 . The so-called change of the thickness according to a predetermined rule can be a gradual increase in the moving direction of the fluorescent sheet 10 according to the color adjustment requirement, or a change in the form of a wave that first increases and then decreases. The phosphor sheet 10 is provided with at least a first ph...
