    摘要： Light-emitting devices, and related components, systems and methods are disclosed. The light-emitting device can include a multi-layer stack of materials including a light-generating region and a first layer supported by the light-generating region. A surface of the first layer can be configured so that light generated by the light-generating region can emerge from the light-emitting device via the surface of the first layer. The surface of the first layer can have a dielectric function that varies spatially according to a pattern that has an ideal lattice constant and a detuning parameter with a value greater than zero.

    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).

    摘要： Techniques for controlling the color of a light source during dimming are provided. A current control circuit may be arranged within a light source module and configured to adjust, according to a driving input current, the current path that passes through some of the lights (e.g., LEDs) in the module. If multiple current paths that pass through these lights have different impedances, a change in current path will cause the amount of current passing through these lights to increase or decrease. If the adjusted lights have a different color temperature than the other lights of the light source module, the change in current path as the driving current is adjusted can effect a change in color temperature as the light source module is dimmed.
