    摘要: 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. A wavelength converting material can have a density per unit area of the emission surface that substantially increases along the length of the light guide.

    摘要: A light-emitting device is provided. The device may include a thermally conductive region in contact with a wavelength-converting region (e.g., a phosphor region). The thermally conductive region may aid in the extraction of heat resulting from light absorption in the wavelength-converting region, which, if excessive, may impair device operation. The presence of a thermally conductive region can enable devices including wavelength-converting regions to operate even at high power levels (e.g., light generated by the light-generating region and/or by the light-emitting device having a total power greater than 0.5 Watts) for long operating lifetimes (e.g., greater than 2,000 hours).
