    Abstract: A notch is formed in a side of an optical sheet. As seen in plan view, the notch is shaped such that the maximum width of the notch as measured in the direction parallel to the line connecting both ends of a mouth portion of the notch is greater than the width of the mouth portion along the side of the optical sheet. Here, it is preferable that the notch be polygonal or have a curved shape as seen in plan view.

  • Publication number: 20090279324
    Abstract: The invention discloses a light guide plate structure. The light guide plate structure includes a light-receiving surface, a light-emitting surface and a light-reflecting surface. The light-receiving surface receives emitting light from at least a light source, and the light propagating in the light guide plate exits through the light-emitting surface. The light-reflecting surface is opposite to the light-emitting surface for guiding the light that passes through the light-receiving surface to the light-emitting surface. The light-emitting surface and/or the light-reflecting surface include at least a composite structure. The composite structure includes a primary structure and a secondary structure where the secondary structure is disposed to a side of the primary structure.

  • Publication number: 20090201301
    Abstract: An integrated illumination apparatus includes a light injection portion having a first end for receiving light from a light source. The light injection portion includes material that supports propagation of said light along the length of the light injection portion. Turning microstructure is disposed on a first side of the light injection. The turning microstructure is configured to turn at least a substantial portion of light incident on the first side and to direct the portion of the light out a second opposite side of the light injection portion. A slit is disposed along the length of the light injection portion. The slit forms an optical interface on the second opposite side of the light injection portion that provides total internal reflection for light propagating along the length of the light injection portion to be guided therein. The optical interface further transmits light turned by said turning microstructure.
