Abstract: 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.

Abstract: The present invention relates to light-emitting diodes (LEDs), and related components, processes, systems, and methods. In certain embodiments, an LED that provides improved optical and thermal efficiency when used in optical systems with a non-rectangular input aperture (e.g., a circular aperture) is described. In some embodiments, the emission surface of the LED and/or an emitter output aperture can be shaped (e.g., in a non-rectangular shape) such that enhanced optical and thermal efficiencies are achieved. In addition, in some embodiments, chip designs and processes that may be employed in order to produce such devices are described.

Abstract: Systems and methods related to the arrangement of regions containing wavelength-converting materials, and associated articles, are provided. Light-emitting diodes (LEDs) can generally provide light in a more efficient manner than incandescent and/or fluorescent light sources. The relatively high power efficiency associated with LEDs has created an interest in using LEDs to displace conventional light sources in a variety of lighting applications.

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.

Abstract: 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.
