  • Patent number: 8110838
    Abstract: Light-emitting devices (e.g., LEDs) and methods associated with such devices are provided. In some embodiments, the device includes a distribution of light-generating portions (including active regions) that are spatially localized and separated (e.g., horizontally or vertically) from one or more patterned light extraction portions. This arrangement can allow light generated by the device to propagate and pass through regions of low absorption (e.g., light-extraction portions) rather than in regions of high absorption (e.g., light-generating portions), which can enhance light emission.

  • Patent number: 8100567
    Abstract: Light-emitting devices can include a package that supports one or more light-emitting die (e.g., light-emitting diode die, laser diode die) and which can ensure mechanically stability, can facilitate electrical and/or thermal coupling with light-emitting die, and can manipulate the manner by which light generated by the die is emitted out of the light-emitting device. The package can also facilitate the integration of the light-emitting devices in various components and systems. For example, suitable packages may facilitate the use of light-emitting devices in components and systems such as light-emitting panel assemblies, LCD back lighting, general lighting, decorative or display lighting, automotive lighting, and other types of lighting components and systems.

  • Patent number: 8092064
    Abstract: Illumination assemblies, components, and related methods are described. An illumination assembly is provided that comprises a plurality of illumination tiles each having a light emission surface. The plurality of illumination tiles are arranged in a two-dimensional array. The illumination tiles are constructed and arranged so as to provide a substantially contiguous illumination surface comprising the light emission surfaces of the plurality of the illumination tiles. Each illumination tile is illuminated by at least one solid state light-emitting device. A method of local dimming an illumination assembly of a display (e.g., LCD) backlight unit is also provided.

  • Publication number: 20110305002
    Abstract: Illumination assemblies, components, and related methods are described. An illumination assembly can include at least one solid state light-emitting device, an emission surface through which light is emitted, and a wavelength converting material that wavelength converts at least some light emitted by the solid state light-emitting device. The wavelength converting material can have a first density per unit area of the emission surface at a first location and a second density per unit area of the emission surface at a second location, wherein the second density is substantially different from the first density, and wherein the density per unit area is defined with a 1×1 cm2 averaging area. Another illumination assembly can include a light guide configured to receive light emitted by a solid state light-emitting device. The light guide can have a length along which received light propagates and an emission surface substantially parallel to the length of the light guide and through which light is emitted.

  • Patent number: 7959341
    Abstract: Illumination systems, which include at least one light source (e.g., LED and/or laser diode), light sensor, and a power source are described. In certain embodiments, a light sensor and a microprocessor are used to detect light emitted by a light source and to adjust the power signal provided to the light source at least partially based on the detected light. Some embodiments may enable the color point and/or brightness of the emitted light to be controlled at least partially based on the detected light. The illumination systems may be designed to be used as a liquid crystal display (LCD), general lighting apparatus, or any other illumination device.
