  • Publication number: 20120132949
    Abstract: According to one embodiment, an LED package includes mutually-separated first and second leadframes, an LED chip, and a resin body. One selected from the first leadframe and the second leadframe includes a base portion, and an extending portion. The base portion has an end surface covered with the resin body. The extending portion extends from the base portion and has an unevenness provided in a surface of the extending portion. A lower surface of the extending portion is covered with the resin body. A tip surface of the extending portion is exposed from the resin body. An exterior form of the resin body is used as an exterior form of the LED package.

  • Publication number: 20120126266
    Abstract: According to one embodiment, an illumination apparatus includes an LED (Light Emitting Diode) module, a light guide plate, and a support body. The support body supports the LED module and the light guide plate. A reflective surface of the support body is provided between a portion supporting the LED module and a portion supporting the light guide plate. The reflective surface is reflective with respect to the light emitted from the LED package. The LED module is tilted relative to the reflective surface with the LED package mounting surface being toward the reflective surface. An angle between the LED module and the reflective surface is less than 90°.
