Abstract: A direct-indirect luminaire is provided with a direct light control structure between the luminaire's light source and the down light openings in the luminaire's housing. The down light control structure has an interior light capture which extends to meet the light source and which is shaped to substantially conform to the shape of a capturable surface of the light source. The down light control structure captures and directs substantially all of the light emitted from the captured portion of the light source through the housing's down light opening to provide improved control over the down light component of the luminaire.

Abstract: A self-tapping sleeve for providing a ceiling junction for a suspended lighting fixture has a cylindrical body, a center passageway for containing the junction, a thread structure on the perimeter surface of the cylindrical body, and two perimeter cutting elements at the top end of the cylindrical body for producing a circular cutting action in front of the sleeve when the sleeve is rotated in and advance rotation. A trim ring is additionally provided at the bottom end of the body to trim out the ceiling junction when the sleeve is installed. A key-shaped portion of the center passageway receives the key-shaped end of a drive tool used to install the sleeve.

Abstract: An improved task light is comprised of a housing having a center cavity portion, a light passage opening below the center cavity portion, and an edge cavity for supporting a light source that emits light from the housing's edge cavity portion into its center cavity portion. A reflector, at least a portion of which spans the center cavity portion of the housing and which portion has a proximal and distal edge in relation to the light source, lies along a path that curves inwardly of the housing such that, when the reflector is viewed through the housing's light passage opening from the level of a task surface below the task light and from any position to the front of the task light, the luminance of the spanning portion of the reflector from reflected source light is substantially uniform over substantially the entirety of the spanning portion of the reflector.
