Color regulating device for illumination and apparatus using the same, and method of regulating color

摘要

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 do not overlap on the traveling path of the light emitted from the light source. Mixing the outgoing light of the light source passing through the light-valving structure with the outgoing light of the light source passing through and at least a portion thereof converted by the color-adjusting structure with a different wavelength band yields a color-adjusted light of different color temperature from that of the light source.

主权项

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 first outgoing light of the light from a fully bright state to a fully dark state, so as to adjust a flux ratio of a first incident light to the first outgoing light of the light interacted with the light-valving structure, the light-valving structure being a member selected from the group consisting of a micro electro mechanical assembly, a color changing glass, an electronic paper, an electrowetting element and combination thereof; 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 do not overlap with each other on a traveling path of the light, such that the first outgoing light and the second outgoing light are mixed to form a hybrid light with a color temperature different from that of the light.
