  • Patent number: 6108060
    Abstract: A surface-type illumination device suitable for providing backlight in a liquid crystal display is disclosed. For example, an L-shaped fluorescent light can be used as an illuminant and mounted next to two edges of a substantially rectangular light guide plate. The corner of an edge portion between the two edges is removed. The fluorescent light, the length of whose illuminating portion is long, is positioned with an appropriate gap from the light guide plate allowing for illumination with high brightness and low power consumption. Consequently, when the illumination device is used in a color liquid crystal display, appropriate backlight with high brightness can be obtained. Moreover, because the influence of the temperature from the illumination device is small, a stable color display can be achieved.

  • Patent number: 5931555
    Abstract: A background lighting apparatus includes a light entering edge surface around substantially the entire periphery of a highly specular transparent plate wherein light beams enter from peripheral light sources and travel toward the central portion of the plate and are dispersed and diffused by a diffusion system formed relative to the transparent plate. Uniformity of luminance provided from the background lighting apparatus is enhanced as a whole by increasing the incident quality of the input light beams into the transparent plate while easing the incident directivity of the light beams on the transparent plate with the overall substantial enhancement of luminance produced from the apparatus.

  • Patent number: 5667289
    Abstract: A background lighting apparatus includes a light entering edge surface around substantially the entire periphery of a highly internally reflecting transparent plate wherein light beams enter from peripheral light sources and travel toward the central portion of the plate and are dispersed and diffused by a diffusion system formed relative to the transparent plate. Uniformity of luminance provided from the background lighting apparatus is enhanced as a whole by increasing the incident quality of the input light beams into the transparent plate while easing the incident directivity of the light beams on the transparent plate with the overall substantial enhancement of luminance produced from the apparatus.

  • Patent number: 5135694
    Abstract: A method of forming an integral intermediate layer in a flexible single injection molded component is disclosed. According to the method a strip comprising the sandwiched layer is securely positioned within a molding cavity. During injection of the mold material a tensile force is applied throughout the strip in a plane orthogonal to a critical component direction. The method is particularly suited for the fabrication of wrist mounted electronic devices having an electrical connection to a conductive member integrally housed within a molded wristband.

  • Patent number: 5130898
    Abstract: A background lighting apparatus comprises a light source arranged adjacent to a light entering end face or surface of a transparent plate and having an irregular reflecting surface or portion on at least one side thereof and wherein the irregular reflecting surface or portion comprises a plurality of milky white type fine lines. The width of the fine lines of uniform pitch monotonically increases across the transparent plate from the light source or the pitch between fine lines of uniform width monotonically decreases across the transparent plate from the light source or the width of the fine lines and the pitch between the lines monotonically increase and monotonically decrease, respectively, across the transparent plate in a direction from the light source.
