    摘要： Illumination assemblies, components, and related methods are described. An illumination assembly can include at least one solid state light-emitting device, and at least one light guide including a light homogenization region configured to receive light emitted by the solid state light-emitting device and including a light output boundary. The light homogenization region substantially uniformly distributes light outputted over the light output boundary. A wavelength converting material can be disposed within at least a portion of the light homogenization region. In some assemblies, a light extraction region can be configured to receive light from the light output boundary of the light homogenization region, and can have a length along which received light propagates and an emission surface through which light is emitted. The light extraction region can include a wavelength converting material disposed within at least a portion of the light extraction region.

    摘要： 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.

    摘要： 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. In some instances, the devices include one or more series of light extraction portions with features arranged in a first and/or second pattern, which may be formed on one or more interfaces of the device (e.g., an emission surface). Patterns can be defined by a series of features (e.g., holes) having certain characteristics (e.g., feature size, depth, nearest neighbor distances) which may be controlled to influence properties of the light emitted from the device, including improving extraction and/or collimation of the emitted light.
