A rod support device including an exterior flange, a female portion configured to receive a telescoping rod, and a male portion configured to extend beyond the surface of a wall. In one aspect, the male portion may include one or more circumferential ribs. In another aspect, the female portion may include a fastener aperture configured to receive a fastener, such as a screw. In yet another aspect, the rod support device may include a cap configured to cover the female portion when not in use. The rod support device may further include an illuminated rod with at least one light transmissive portion and a light source configured to emit light through the light transmissive portion.

The invention provides an acoustic panel comprising a plurality of parallel-arranged elongated cavities, wherein each cavity has a first cavity wall and a second cavity wall tapering to a cavity back end and defining a cavity opening angle (γ) having a value in the range of 0°<γ<90°, wherein the first cavity wall and the second cavity wall comprise a light-reflective material, wherein each elongated cavity at the cavity back end of the elongated cavity accommodates a light source having a light exit surface, wherein the first cavity walls hide the light exit surfaces of the light sources when the acoustic panel is viewed along a normal to the acoustic panel, and wherein the acoustic panel further comprises sound reducing material.

Disclosed is a sound absorbing lighting panel (100) comprising a sound absorbing member (120); an optical medium (130) over said sound absorbing member; a first set (140) of solid state lighting elements (142) arranged along a first edge of said optical medium; a translucent sheet (150) over the optical medium, said translucent sheet having a non-uniform degree of translucency such as a higher degree of translucency over a central region of said optical medium than over a first region of said optical medium comprising said first edge. A modular surface system including such a sound absorbing lighting panel is also disclosed.

A lighting system comprises a light source having an exit window and an electrically controllable light processing arrangement, in the form of a grid of cells lying in a plane parallel to the exit window. Each cell has a cell wall formed as electrically switchable element which is switchable between at least two processing modes. The cell wall surrounds an opening, such that light emitted in a normal direction from the light source exit window is not processed, and light passing at an angle to the normal direction greater than a threshold angle is processed by the cell wall for color and/or intensity control.

A merchandiser including a case that defines a product display area and a luminaire that is coupled to the case to illuminate at least a portion of the product display area. The luminaire is slidably and rotatably coupled to the case at a single point.

A ribband for a stretched fabric three-dimensional structure comprising at least one light source incorporated in the ribband, wherein the ribband comprises two adjacent recesses separated by a tongue designed to receive the fastening elements of the stretched fabrics, wherein each recess comprises a bottom, an inner side wall forming the tongue and an outer side wall, wherein each outer side wall defines a peripheral wing of the ribband.

An aspect of the invention relates to a floor construction, comprising: o plural layers, the plural layers comprising at least one top layer and at least one subjacent layer underneath the at least one top layer, o and light sources arranged in one or more patterns in the at least one subjacent layer; o wherein the at least one top layer is translucent so as to hide the light source as well as the patterns when the light sources are off and to reveal the one or more patterns when the light sources are on.

An illumination panel including an optically transmissive, hollow multiwall structure and an array of LED strips distributed within a series of hollow chambers formed by the multiwall structure. The hollow multiwall structure is formed by two or more sheets of optically clear or translucent material joined by a plurality of transverse ribs. Each LED strip includes an array of interconnected light emitting diodes and is preferably provided with one or more light diffusing or beam-shaping elements included into one or more hollow chambers.

Devices used for workspace illumination include, for example, a panel and a solid-state based optical system arranged inside an enclosure of the panel. The panel can be a cubicle divider. In one aspect, an illumination device includes a mount; a panel including a first face and a second opposing face. The panel is vertically supported by the mount along a horizontal dimension of the first and second faces. Further, the panel forms an enclosure between the first and the second face. Additionally, the illumination device includes a first luminaire module arranged in the enclosure and configured to output light in a first output angular range. The light output in the first output angular range has a prevalent propagation direction with a vertical component towards a first target area.
