<P>PROBLEM TO BE SOLVED: To provide a color temperature-regulating device for illumination, a color temperature-regulating apparatus using the color temperature-regulating device, and a color temperature-regulating method. <P>SOLUTION: A color temperature-regulating device for illumination, configured to regulate a color temperature of light interacting with the device, comprises: a light-valving structure for adjusting a ratio between an outgoing light flux that passes through the light-valving structure and an incident light flux incident on the light-valving structure; and a color-adjusting structure having at least one wavelength-band converting element, configured to convert an incident light with a wavelength band into an outgoing light with a different wavelength band, wherein the light-valving structure and the color-adjusting structure do not overlap with each other on a traveling path of the light, such that the outgoing light that is emitted from a light source and passes through the light-valving structure and the outgoing light that passes through the color-adjusting structure and a part of which is converted into a different wavelength band are mixed, thereby forming a hybrid light with a color temperature different from that of the original light source. <P>COPYRIGHT: (C)2013,JPO&INPIT |
