Abstract: Techniques are disclosed to operate a luminaire so as to reduce glare experience by an occupant within an area illuminated by a luminaire. The luminaire includes individually operated light sources. An image capture device is deployed for capturing an image of an area. Operatively coupled to the luminaire and the image capture device is a computing system. The computing is configured to reduce glare by adjusting a light intensity of a light source of the luminaire. These adjustments are based on, for example, a position of an occupant within the area and a direction in which the occupant is facing relative to the luminaire, and/or a position of an indirect glare source.

Abstract: A luminaire having an electronically adjustable light beam distribution is disclosed. In accordance with some embodiments, the disclosed luminaire includes a housing, for example, of hemi-cylindrical, oblate hemi-cylindrical, oblong elliptical, or polyhedral shape. The disclosed luminaire also includes a plurality of solid-state light sources arranged over its housing, in accordance with some embodiments. The one or more solid-state emitters of a given solid-state light source may be addressable individually and/or in one or more groupings, in some embodiments. As such, the solid-state light sources can be electronically controlled individually and/or in conjunction with one another, providing for highly adjustable light emissions from the host luminaire, in accordance with some embodiments. One or more heat sinks may be mounted on the housing to assist with heat dissipation for the solid-state light sources.

Abstract: A single-ended arc discharge vessel for a metal halide lamp includes a U-shaped arc discharge chamber that has two juxtaposed subchambers with a divider wall therebetween and a passageway around the divider wall that connects the two subchambers to each other. The vessel has two parallel electrodes in a same end of the vessel that is opposite the passageway. Each of the electrodes extends into a respective one of the two subchambers a distance less than a height of the divider wall so that the arc discharge between the electrodes is U-shaped. This arrangement moves the vessel cold spot away from the electrodes to permit higher operating temperatures and increases arc gap length for a given vessel size to permit a higher lamp voltage.
