Inventive methods and apparatus for providing an open wall wash luminaire designed to allow a small amount of light to go behind the luminaire kick reflector, resulting in the kick reflector being less noticeable by an occupant of the room when light is being provided by the luminaire.

Kick reflector for wall wash applications

The present invention relates to a louvre lighting unit which contains a plurality of louvre cells for beam shaping the lighting unit light. The plurality of louvre cells comprises a plurality of n subsets, each comprising a respective plurality of m louvre cells. The louvre cells of each subset are configured as a domain of adjoining louvre cells, wherein a respective plurality of k louvre cells within each domain have mutually differing louvre cell cross-sections.

Pebble-plate like louvre with specific domain characteristics

The invention provides a lighting unit () comprising a light mixing chamber () defined by faces () and an edge face (), wherein a height (H) of the light mixing chamber () defined by a distance between the faces () is smaller than a first length (L) of the light mixing chamber (), wherein the lighting unit comprises a plurality of light sources () configured to provide light source light () in the light mixing chamber (), wherein at least one of the faces () comprises a plurality of chamber openings () for escape of at least part of the light source light () from the light mixing chamber (), wherein the lighting unit () further comprises a plurality of beam shaping elements (), with each beam shaping element () configured downstream from a corresponding chamber opening (, and wherein the beam shaping elements () comprise reflectors ().

A luminaire housing designed to be installed to illuminate an illumination area, wherein a light source is oriented within the housing to direct a central axis of emitted light rays away from the illumination area and towards a reflective surface of a stationary reflector. In some embodiments the stationary reflector is oriented and contoured to reflect the light rays towards a light spread lens having one end positioned above at least a portion of a reflector lip and angled into the housing with respect to a light passageway. Optionally, the luminaire housing may be a recessed luminaire housing.

Color mixing luminaire

A luminaire housing designed to be installed to illuminate an illumination area, wherein a light source is oriented within the housing to direct a central axis of emitted light rays away from the illumination area and towards a reflective surface of a stationary reflector. In some embodiments the stationary reflector is oriented and contoured to reflect the light rays towards a light passageway. In some embodiments, an adjustable reflector is also provided that is movable between at least a first and a second position. Optionally, the luminaire housing may be a recessed luminaire housing.

A recessed downlight wall wash reflector assembly having a wall wash reflector installable into a standard mounting frame for a recessed downlight reflector having a similarly sized light exit aperture. The reflector assembly has a downlight reflector, a window cutout in the wall of the downlight reflector and a wall wash reflector attached to the reflector assembly such that it is positioned behind the window cutout and has a lower tab that extends into the lower portion of the window cutout providing for a higher angle of reflection of light from nadir.
