Abstract
There is provided a color regulating device for illumination. The color regulating device includes a light-valving structure for adjusting a flux ratio of outgoing light through the light-valving structure to incident light entering the light-valving structure, and a color-adjusting structure having a wavelength-band converting element for changing incident light with a wavelength band into outgoing light with a different wavelength band through the element. Wherein, the light-valving structure and the color-adjusting structure at least partially overlap on the traveling path of light, forming at least one overlapping structure. Mixing the outgoing lights of the light source passing through light-valving structure, the color-adjusting structure, and the overlapping structure to obtain a different wavelength band (or color temperature) from that of the light source. There are also provided a color adjusting apparatus for illumination including the color adjusting device and a color adjusting method.
