  • Publication number: 20030042844
    Abstract: In an LED device, an opening portion of a package in which a plurality of five light-emitting elements are mounted is filled with a transparent epoxy resin and sealed with the resin. The transparent epoxy resin is shrunk when cured. Hence, the surface of the transparent epoxy resin is dented in the center portion so that the outer edge portion becomes higher than the center portion. The light-emitting elements located at opposite ends are the highest in element height among the five light-emitting elements. Hence, when the light-emitting elements are mounted at opposite ends of a single row, distances from light-emitting surfaces of the five light-emitting elements to the surface of the transparent epoxy resin are made uniform and luminous intensity distribution characteristics thereof are made uniform. Tips of leads are further bent up along side surfaces of the package.

  • Publication number: 20020080301
    Abstract: A light source in a backlight portion is composed of red LEDs, green LEDs, and blue LEDs. The numbers of respective kinds of LEDs used are selected so that the number of blue LEDs is not smaller than the number of red LEDs and the number of blue LEDs is not smaller than the number of green LEDs.

  • Patent number: 5843264
    Abstract: The present invention is directed to a vibration insulating assembly including a rubber vibration insulator and metallic members bonded thereto. In particular, the present invention relates to a method for manufacturing the same, by which the quality of the resulting assembly is improved by providing a high bonding strength between the vibration insulator and metallic members. Retainers are provided about the peripheries of the bonding surfaces of the rubber vibration insulator in order to restrict displacement and deformation of the rubber vibration insulator across the bonding surfaces or at the bonding interface with the metallic members and to facilitate its positioning. The presence of the retainers allows for the application of a predetermined pressure on the bonding surfaces to enhance the bonding strength while preventing an undesirable strain from forming in the bonding surface of the rubber vibration insulator.
