A light emitting diode (LED) lighting device is provided having a front housing having an outer profile and a shape formed from a translucent or transparent material. The front housing has an edge protrusion extending from a front housing body along the outer profile. The edge protrusion bounds an inner light chamber. A rear housing is separately provided having a size and outer profile substantially corresponding to the shape of the front housing. The rear housing is opaque or impervious to light, and has a substantially planar rear panel and a rear panel protrusion extending from the rear panel adjacent to and spaced apart from an outer edge of the rear housing. The rear panel protrusion and the rear panel further bound the inner light chamber. At least a portion of the edge protrusion surrounds the rear panel protrusion.

A light emitting diode (LED) lighting device includes a frame having a substantially consistent cross-sectional profile and an inner surface; a front panel having a front surface sized and shaped to substantially correspond to the inner surface of the frame, a rear surface having a shape substantially corresponding to the shape of the front surface and a size smaller than the front surface, an edge profile extending from the front surface to the rear surface; and an adhesive positioned between the edge profile adjacent the rear surface of the front panel and the inner surface of the frame; a rear panel sized and shaped to correspond to the frame and spaced apart from the front panel a distance about the thickness of the frame; and at least one LED mounted on the rear panel.

Light emitting diode (LED) light tubes having rotatable end cap assemblies are described. The LED light tubes include a hollow tube and a circuit board with LED chips thereon. The end cap assemblies are provided on either end of the tube. Each end cap assembly includes a socket cap, a plug having a plug body and at least one connector, and an end cap body, one end of which engages one of the ends of the hollow tube. A cam locking mount that is positioned within the plug body and on the opposite side has projections to be positioned in the bore of the end cap body. A rotation cam is seated in the cam locking mount and provides for controlled rotation of the LED tube relative to the end caps. Methods of installing the LED light tubes in new installations and retrofit installations and for use in sign assemblies are also described.

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.

A display module (102) comprises light-emitting elements (106) coupled to one or more mounting structures and grouped into a pixels in a pixel array on a display face to display textual, graphical, or video information, with each pixel comprising a grouping of one or more light-emitting elements. A face cover (100) is mounted to the mounting structure and is positioned in front of at least a portion of the display face. The face cover comprises a plurality of moguls (110) arranged in a mogul array with each mogul positioned in front of and proximate to a corresponding one of the pixels so that the mogul covers at least a portion of the corresponding pixel, and one or more light-emitting openings (112) in each mogul, each positioned relative to one or more corresponding light-emitting element of the pixel to permit light emitted from the corresponding one or more light-emitting elements to pass through the mogul.

A branding device includes a housing, a faceplate, a backlit recess within the housing, housing retention features, and faceplate retention features. The branding device is configured to be installed within a corresponding recess of a panel, such that the faceplate can be removed and replaced without requiring replacement of the entire branding device. To update the branding information of the branding device, the faceplate retention features must be disengaged from the rear of the branding device, the faceplate is then removed, and a faceplate with updated branding information is then installed.

A sales or test display, comprising, in the assembled state, a lower level (14) for receiving products, a lighting system (16), and an upper level on which the lighting system is fastened, the lighting system comprising: a base (24), a printed circuit board (22) including a light-emitting diode suitable for emitting a light (L1), and a guide (26) made from a translucent material extending along a line (L), and located opposite the light-emitting diode to conduct said light, the guide (26) comprising: an upper surface for downwardly reflecting at least part of the light (L1) and forming a reflected light, and a lower surface for allowing at least part of the reflected light to pass and forming a diffused light (L3), the guide being configured to form an illuminated zone (20) on the lower level.

A lighting system for a hat includes a front housing containing lighting elements that mates with a back plate positioned on the inside of the hat. Driver circuitry controls operation of the LEDs for various lighting modes, and a cover for the front housing is translucent and designed in the shape of a recognizable logo or other design. Electric power comes from a battery located on the back plate, and is provided through the hate using prongs or projections that pass through the hat, from the back plate to a circuit connector in the front housing. The circuit connector is electrically coupled to circuitry on a circuit board in the front housing.

A display device includes a plurality of moveable display units, and at least one external control device for emitting control signals in dependence on which at least some of the plurality of display units form a display, the display units each being connected at different locations via coupling means and capable of being detachably connected to one another, where at least some of the display units include at least one detection device for detecting a relative position of at least one further display unit, and the at least one detection device is a sensor which detects at least one adjacent display unit.
