Abstract:
1. A color regulating device for illumination, configured to regulate a color temperature of light interacting with the device, comprising: a light-valving structure for adjusting a flux ratio of a first incident light to a first outgoing light of the light interacted with the light-valving structure; and a color-adjusting structure having at least one wavelength-band converting element, configured to convert a second incident light with a first wavelength band into a second outgoing light with a second wavelength band, wherein the light-valving structure and the color-adjusting structure at least partially overlap on a traveling path of the light, forming at least one overlapping structure, such that at least a portion of the light becomes a third outgoing light, and the first outgoing light, the second outgoing light and the third outgoing light are mixed to form a hybrid light with a color temperature different from that of the light, wherein the hybrid light is further mixed with a portion of the light not interacted with the device.
