The invention relates to a multi-layer element which can be illuminated with edge lighting and optionally also with backlighting, an which has a stone-like appearance. Alongside the stone layer, layers made of a thermoplastic material are also provided. The structure is not only an attractive design element with day/night design for building interiors and facade construction, but it can also be used in many ways in the automotive sector.

What is described as a multilayer body which can be illuminated by means of edge lighting and optionally also by backlighting, and which has a stone look. As well as the stone layer, layers of thermoplastic material are provided, with a translucent dark-colored layer provided on the reverse side with respect to the stone layer. The structure is a pleasing design element with day/night design not just in the configuration of building interiors and facades, but can also be used in a versatile manner in the automotive sector.

Structures, particularly wall and/or pillar structure, comprising a supporting portion and a covering portion for covering the supporting portion, the supporting portion being provided by solid material pieces and at least one string for jamming at least some of the solid material pieces, wherein the covering portion comprises at least one covering device and wherein the string and the covering device are attached to each other.

A light fixture, e.g., as an artificial skylight, in which light within a region defined by x, y color coordinates (0.37, 0.34), (0.35, 0.38), (0.15, 0.20), and (0.20, 0.14) exits a first light engine, and light within a region defined by coordinates (0.29, 0.32), (0.32, 0.29), (0.41, 0.36), (0.48, 0.39), (0.48, 0.43), (0.40, 0.41), and (0.35, 0.38) exits a second light engine. Also, light fixtures in which a second light engine comprises a sidewall, and light exiting a first light engine passes through space defined by the sidewall; light fixtures in which first and second light engines are able to output light providing different CS values at a luminance; light fixtures in which light incident on a surface of the fixture and cumulative light exiting the fixture have different color points; light fixtures in which light distribution characteristics of light engines differ; and/or other features. The invention also relates to corresponding methods.

The disclosure relates in general to illuminated panels resembling windows, and more particularly, to a system containing a light source, a diffuser and a panel combined in such a fashion as to resemble a window, skylight or curtain wall.

A luminaire structure, comprises a plurality of housing segments, each with at least one lighting zone, and configured to be assembled to form a support structure defining at least one panel supporting zone for supporting at least one acoustic panel removably attached thereto, wherein each of the lighting zones in the support structure is oriented to be adjacent the at least one acoustic panel, and operable to receive a lighting module to deliver light to an interior space.

A lighted railing assembly with at least one railing member includes an inner cavity, a battery disposed within the inner cavity and a lighting device powered by the battery. A solar panel is integrated into the railing member and is electrically coupled to charge the battery. A controller is configured to control charging of the battery and activation of the lighting device in response to a signal provided by an ambient light sensor.

A tiltable solar disk light has a solar light disk body comprising a disk-shaped housing which houses solar cells, LEDs, a rechargeable battery, a pushbutton switch, and driver electronics configured to deliver power to the LEDs from the battery when the switch is in the ON position and the solar cells are not detecting ambient light and to cut off power to the LEDs when the switch is in the OFF position or the solar cells are detecting ambient light. The disk body is tiltably and rotatably supported in a frame, on a pair of pegs extending from the housing, with enough clearance space about the disk body to permit tilting and rotating within the frame. A landscape spike is optionally connected to the frame by curved arms configured to define a clearance gap between the spike and the frame to permit the disk body to tilt within the frame about the axis of rotation formed by the pegs.

A grab rail (10) includes an elongate central grip region (12) extending in a linear direction and two end portions (14). Each end portion (14) includes an elbow formation (18) extending from and contiguous with the grip region through to a direction generally transverse to the grip region and terminating in a surface engaging formation (20). The central grip region (12) includes a photo luminescent material that accumulates energy under normal or day light conditions and automatically emits light under low light conditions to glow in the dark. The grab rail does not require a power source and provides enhanced visibility in low or dark lighting conditions, and is particularly useful in care facilities and where people suffer from mobility issues.

Systems, methods, and computer program products for providing and managing a lighting system. A lighting device of the system is configured to receive an activation signal from a user interface of the lighting device, an external communication device, or another lighting device. In response to receiving the activation signal, and if certain operational conditions are met, the lighting device may activate a light source and transmit another activation signal. Additional lighting devices receiving the activation signal from the first lighting device may also activate their light sources and retransmit the activation signal. Data carried by the activation signals and signals received from one or more sensors in each lighting device may be used by the lighting device to determine whether to activate its light source, and one or more characteristics of the light to be emitted.
