  • Publication number: 20160017228
    Abstract: A liquid-crystal film includes a liquid crystal mixture with the gel state. The liquid crystal mixture is formed of at least one ?-conjugated polymer gelator and a liquid-crystal unit. The concentration of the at least one ?-conjugated polymer gelator is 0.05-5 wt %. The concentration of the liquid-crystal unit is 95-99.95 wt %. The at least one ?-conjugated polymer gelator is aligned through the liquid-crystal unit and combined together to form a plurality of fibers. The fibers include at least 60% arranged regularly in direction and some of the fibers are linked with one another to form a network structure.

  • Patent number: 9164316
    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.

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.
