  • Patent number: 7311420
    Abstract: In one embodiment, an opto-electronic package includes a substrate, a cavity, mounting pads and transverse walls interspersed along the cavity, pads separated by transverse walls, and transverse walls being lower than cavity-defining walls; and LED dice mounted to the pads. In another embodiment, a system is disclosed for backlighting an LCD screen. The system includes an opto-electronic package having a substrate; LED dice mounted to the substrate; an encapsulant disposed over LED dice; and a light guide having an input portion to receive light provided by LED dice, the input portion in attachment to encapsulant, and an output portion configured to transmit light to LCD screen. In yet another embodiment, a method of manufacturing an opto-electronic package includes: fabricating a substrate; attaching LED dice to the substrate; electrically connecting each LED dice to an outer portion of the substrate; and disposing encapsulant over the LED dice.

  • Patent number: 7309151
    Abstract: In one embodiment, a light emitting panel includes a base panel and a plurality of light emitting elements mounted to the base panel. Each of the light emitting elements produces an illumination pattern having a region of substantially uniform intensity that extends over a radiation angle of at least about 60°. One or more light conditioners are positioned adjacent the base panel to receive and condition light produced by the light emitting elements.

  • Patent number: 7293906
    Abstract: An apparatus having a light source, a reflector, and a light pipe is disclosed. The light source includes a plurality of LED dies arranged in an array along a first direction, each LED die emitting light in a second direction. The light pipe includes a layer of transparent material having a top surface, a bottom surface, and an edge surface. The reflector reflects light from the LED dies traveling in the second direction into the edge surface of the light pipe such that a portion of the light is reflected by the top and bottom surfaces of the reflector. In one embodiment, the reflector redirects light leaving the LED dies within a predetermined cone of angles about the first direction into the light pipe such that the light in that predetermined cone of angles is totally reflected by the top surface of the light pipe.

  • Patent number: 7262438
    Abstract: There is disclosed a system and method for increasing heat dissipation of LED displays by using the current PCB packaging mounted to a LCD panel support structure thereby eliminating the need for a metal core PCB. In one embodiment, reverse mounted LEDs having heat dissipation pads are used to optimize heat transfer to a metal layer which is then placed in contact with the LCD support structure.
