A backlit display system includes a display framework and a display fabric. The display frame has an inner perimeter defining a central open space and having mounted thereabout a plurality of light-emitting elements configured for emitting light into the central open space. The display fabric has a rearward, light-reflective back-lighting panel and a forward, light-permeable image-display panel supported by the display frame such that at least a portion of the central open space is situated between the back-lighting and image-display panels. A portion of the light emitted into the central open space from the light-emitting elements is reflected by the back-lighting panel toward the image-display panel through which it passes to illuminate an image defined on the image-display panel.

A shelf illumination device (1) for illuminating a shelf board of a shelving system. The device (1) is mounted on a component such as the shelf board. An illumination unit (4) with a plurality of light source is attached to an illumination support (3) to illuminate at least one of the shelf boards. At least one partially transparent label holder (5) receives at least one label, a shelf marking or the like. At least one light guide (6) at least in sections extends between the illumination support (3) and the label holder (5). The light guide (6) is constructed and arranged so that a portion of light emitted by the illumination unit (4) is coupled into and propagates through the light guide (6) to at least partially backlight the label holder (5), whereas the remaining portion of the light emitted by the illumination unit (4) illuminates the shelf board.

An aircraft interior light unit having a light output over an extended light emission area includes a flat light distribution body having a front surface, through which the light output is coupled out, and a back surface, wherein at least one of the front surface and the back surface of the flat light distribution body has a plurality of surface irregularities.

One embodiment provides a mapping device including a memory configured to store instructions. A processor is configured to execute the instructions to: receive geolocation information for the mapping device from a global positioning system (GPS) device; receive unique identification information; transmit the geolocation information and the unique identification information through a network; and cause an update to prior geolocation information that corresponds to an address in a mapping database.

A self-contained illuminated sign for mounting on a vehicle is disclosed. The sign includes a front panel, a rear panel situated opposite and substantially parallel to the front panel in spaced relation therefrom to define a space therebetween, and a light source comprising a plurality of LEDs. The light source is positioned between the front and rear panels and is configured to emit light that emanates from the front panel. The front panel is thus backlit to display indicia. A system for supporting a self-contained illuminated sign on a vehicle is also disclosed. The system includes the sign and a separate mounting frame mountable on a vehicle. The mounting frame is configured to removably receive the sign and, when the sign is received in the mounting frame, to surround a perimeter of the sign while permitting visibility of the front display area. Related methods are also disclosed.
