  • Patent number: 7915618
    Abstract: A pair of bonding electrodes of each of light-emitting semiconductor devices of RGB is disposed in a point symmetrical relationship, the devices are mounted on a common electrode of a package, and a bonding wire is suspended from a commonized bonding electrode of the respective devices to the common electrode. Bonding wires are suspended from the other bonding electrodes of the respective devices to first to third electrodes on the package which are independent from one another.
    Type: Grant

  • Patent number: 7393122
    Abstract: The present invention provides a lamp that includes a reflection case and a light emitting element. A central portion of a lower wall inner face of the reflection case is stepwise lowered to form a lower wall enlarged inner face, and both faces are made continuous with each other through right and left perpendicular hanging inner faces, so that a central portion of a back wall inner face and a front opening are downwardly enlarged in a rectangular shape, respectively. The light emitting element is mounted on a front face of a sub mount table. A back face of the sub mount table is fixed to the central portion of the back wall inner face, and right and left end faces of the sub mount table are positioned to right and left perpendicular hanging inner faces when the sub mount table is fixed.

  • Patent number: 7332862
    Abstract: In an LED lamp, a copper film is first formed on a substrate by plating. A resist is then bonded onto the copper film so that shaped like a ring viewed from the whole of the LED lamp. A nickel and a gold film are formed on a portion of the copper film where the resist is not bonded. Next, an adhesive agent is applied onto a bottom of the lamp house so that the lamp house is bonded onto the substrate through the adhesive agent. A transparent epoxy resin is packed in the frame of the lamp house and hardened by heating to perform resin sealing. Since the resist is bonded onto the surface of copper having a large number of fine irregularities sufficient to ensure a large contact area and excellent in adhesion, separation can be prevented from being caused by thermal stress.
