The adjusted portion of the package is positioned so that air can be used as the second (exterior) medium with the critical TIR angle being such that light emitted from a light source (such as from an LED die) will be directed primarily so as to escape the package from the top surface as opposed to being scattered internal to the package. In one embodiment, a lower portion of the encapsulant is surrounded by a casing to inwardly direct light from the light source that impacts the side of the encapsulant with an angle less than the critical TIR angle.

  • Patent number: 7960733
    Abstract: It is an object of the present invention to provide a high reliable EL display device and a manufacturing method thereof by shielding intruding moisture or oxygen which is a factor of deteriorating the property of an EL element without enlarging the EL display device. In the invention, application is used as a method for forming a high thermostability planarizing film 16, typically, an interlayer insulating film (a film which serves as a base film of a light emitting element later) of a TFT in which a skeletal structure is configured by the combination of silicon (Si) and oxygen (O). After the formation, an edge portion or an opening portion is formed to have a tapered shape. Afterwards, distortion is given by adding an inert element with a comparatively large atomic radius to modify or highly densify a surface (including a side surface) for preventing the intrusion of moisture or oxygen.

  • Patent number: 7960748
    Abstract: A semiconductor light emitting device is provided so that an optical axis thereof is properly set parallel with the mounting board when the device is mounted on the mounting board. The semiconductor light emitting device can have a structure in that light can be incident on the light guide plate with high efficiency and uniform introduction into the light guide plate. A multi-piece substrate can include electrodes, a plurality of semiconductor light emitting elements, and a sealing resin for sealing them simultaneously. The thus obtained integrated substrate is cut into individual semiconductor light emitting device bodies. On one of the cut end faces, which serves as a surface to be mounted onto a mounting board, a light-shielding reflective film can be coated over an area from the edge of the light emission surface of the sealing resin to at least part of the substrate. On the other cut end face, the sealing resin can be covered with a light-shielding reflective film.
