  • Light emitting diode display device comprising a high temperature resistant overlay
    Patent number: 7675231
    Abstract: A light emitting diode display device includes a substrate having a first conductive portion and a second conductive portion. A light emitting diode die is coupled to the first conductive portion. A wire bond is coupled to the light emitting diode die and coupled to the second conductive portion. An encapsulant encases the light emitting diode die and the wire bond above the substrate. An overlay is above the encapsulant, wherein the overlay has a high glass transition temperature.

  • Method and apparatus for mixing light emitted by a plurality of solid-state light emitters
    Patent number: 7315048
    Abstract: In one embodiment, light emitted by a plurality of solid-state light emitters is mixed by mounting the plurality of solid-state light emitters on a transparent to translucent substrate so that they primarily emit light away from the substrate. The light emitters are then covered with a transparent to translucent encapsulant; and the encapsulant is coated with a reflective material that reflects light emitted by the light emitters toward the substrate. Related apparatus is also disclosed.
