  • Patent number: 11644716
    Abstract: Embodiments of the present disclosure are related to a backlight unit and a display device, and the backlight unit in which an optical plate including an engraved pattern in which a color conversion material is disposed is positioned on a light source can be provided. As the color conversion material is disposed in the engraved pattern, a change of the color conversion material by an external factor can be prevented and an amount of the color conversion material can be reduced, thus the backlight unit providing an image quality greater or equal to a certain level and with improved reliability can be implemented easily.

    Abstract: The present invention is directed to a light housing installed in close proximity to a light source. The light housing has a shield and an attachment arm for securing the shield. The attachment arm allows the shield to be removably attached in close proximity to the light source. The housing optionally has an aperture allowing the housing to be installed over and/or around the light source. The housing at least partially blocks light emanating from a light source, such as an in-ground staked floodlight, and keeps the light from shining directly into the eyes of a person observing the light source. The housing also hides the unsightly components of a light source.

  • Patent number: 7393123
    Abstract: An apparatus for uniform illumination includes a light source and one diffuser shield maintained in proximity with the light source to uniformly disperse light from the light source. The diffuser shield is formed at least by an outer filter having a concave and perforated surface, and a translucent interior disk having two outer layers of transparent glass and an inner layer of white glass. The light source might be an induction lighting unit including a high frequency generator and might be associated with a supporting structure.

  • Patent number: 7384172
    Abstract: A portable lamp for demonstration of a sports theme comprises: a) a base; b) a supporting member projecting from the base having an upper end portion; and, c) a generally spherical light source carrying lamp head, carried by the upper end portion of the upright shaft, having an outer segment and a diametrically smaller inner segment, said segments generally semi-spherical and having opposite end portions pivotally attached. Then the segments can be rotated closed to generally form a sphere, or alternatively rotated so that the sphere then has an open segment and the light source therein can radiate light therethrough. Light emitted through the open segment can be controlled by varying a width of said open segment. Most preferably the supporting member comprises an upright shaft capable of manipulation so that its upper end portion can be positioned at a selected angular orientation with respect to the base.

  • Publication number: 20080117639
    Abstract: For manufacturing a light-guiding plate and a key module having the light-guiding plate, a mold is prepared first. Then, a material having high light transmittance is injected into the mold. After the plastic material is formed, the mold is released, so that the plastic material is formed into a sheet-like light-guiding plate, and one surface of the light-guiding plate is formed with a plurality of light-guiding portions thereon. The light-guiding plate is disposed in the key module of an electronic device. The light generated by light-emitting elements within the electronic device is introduced from the front end of a substrate of the light-guiding plate, and the light is refracted by the light-guiding portion to a corresponding key, thereby to display the numeral or pattern of the surface of a key cap of the key.

  • Patent number: 7198388
    Abstract: Light control grids in curved ceilings or walls include an assembly of flexible, spaced-apart sets of fabric strips that intersect and interlock, one of the sets of strips being substantially curved along its length and/or of varying length. The grids are supported by a modular rigid framework that maintains the strips taut, the frames being substantially curved corresponding to the curved strips and/or strips of varying length. A number of connectors hold the frames together and are used to attach the assembly to the building, and a number of releasable fasteners moveably retained by the frames attach the grids to the frames.

  • Patent number: 7188970
    Abstract: An illumination device for simulating neon lighting comprises a rod-like member having a predetermined length and a curved light emitting surface, an elongated light source extending substantially along the predetermined length of the rod-like member at a fixed distance from the light emitting surface, and a housing for said elongated light source. The housing includes opposing and substantially parallel side walls with internally light reflecting surfaces, such that the housing serves to collect and direct light emitted by said light source into the rod-like member, with such light then passing through and being scattered by the rod-like member so as to exit the curved light emitting surface in a substantially uniform light intensity pattern.
