Toshinari Shibasaki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7927520
    Abstract: The lighting apparatus includes a light source, a housing that contains the light source inside and has an exit port for outputting light from the light source, and an optical sheet that is placed in the exit port. The optical sheet includes a lens structure that is placed at a light exit side and aligns an output direction of incident light from the light source, a reflector that is placed at a light incident side and reflects light emitted by the light source, and a light transmitting opening that exists in the reflector and transmits incident light from the light source. The light transmitting opening is placed in a position deviated from an optical axis of the lens structure. The display apparatus includes the lighting apparatus.

  • Patent number: 7878670
    Abstract: Provided is an illumination apparatus for a liquid crystal display apparatus having a plurality of transmission parts arranged two-dimensionally, having a plurality of aspherical lenses, which is installed in response to each of a plurality of the transmission parts and concentrates light for each of a plurality of the transmission parts; a plurality of light emission parts R1 installed in response to each focal point position of a plurality of the aspherical lenses; and an electroluminescence layer containing a non-light emission region R2 installed between a plurality of the light emission parts R1 themselves. Each of a plurality of the aspherical lenses has an inner side lens face containing an intersection with an optical axis AX, and an outer side lens face enclosing said inner side lens face, and curvature in the outer side lens face is smaller than curvature in the inner side lens face.

  • Patent number: 7837343
    Abstract: An illuminating device includes a light-condensing sheet, a light-emitting portion, and a control unit. The light-condensing sheet includes a plurality of lenses each with a light-condensing function ranged on a light transmittance substrate. The light-emitting portion is opposed to the light-condensing sheet and includes light-emitting areas with respective dimensions. The control unit switches a luminous state of the light-emitting area to a non-luminous state or vice versa. A display device is provided with the illuminating device described above.

  • Publication number: 20090080196
    Abstract: A lighting apparatus includes a light source and a light beam separating member to separate light emitted from the light source into at least two different directions. The light beam separating member has a light incident plane on which light emitted from the light source is incident and a light output plane from which the light is output after being transmitted through the light beam separating member. In this structure, output light from the light beam separating member is clearly separated. Further, output light from the light beam separating member has characteristics that an angular width of each separated light beam is narrow.
