According to the present invention, there is provided a display apparatus (D) having a colored light-transmitting base material (10), a black light-transmitting member (56) containing a black colorant, and a light source unit (40), in which the light source unit (40) is disposed such that emission light of a light source is transmitted through the colored light-transmitting base material (10) and the black light-transmitting member (56) in this order, a total light transmittance (T) of a layer obtained by combining a layer of the colored light-transmitting base material (10) and a layer of the black light-transmitting member (56) is 13% or less, and the black light-transmitting member (56) has an L* value of 45 or less. The display apparatus (D) has excellent designability and high luminance.

A light box having a front part and a rear part. The front part, a printable, translucent, and rollable front plastics plate, forms a front side with a perimeter edge. The front part has a peripheral first connecting strip fixed on the front plastics plate to extend at least substantially along the entire perimeter edge of the front plastics plate. The rear part has a rollable rear plastics plate forming the rear side with a perimeter edge. The rear part has a peripheral second connecting strip fixed on the rear plastics plate to extend at least substantially along the entire perimeter edge of the rear plastics plate. At least one electrical light-emitting unit is arranged on an inside of the rear plastics plate opposite the rear side. The front part is fixed in front of the rear part by the first and second connecting strips.

A modular and decentralized architecture for building illuminated means of egress from a device level to a building system level, wherein low and high mounted illuminated means of egress inside a building can use the same luminaire form factor.

The systems and methods of the present disclosure provide film-ready solar signs and assemblies for installations of solar signs.

A system and method are disclosed for a lamp that includes a unit capable of receiving various inserts that allow the lamp to adapt in appearance for changing the decor of a room and/or provide information to a user in proximity to the lamp.

An illumination set has a plurality of alphabet lamps and a plurality of connectors. Two of the alphabet lamps are connected by one of the connectors. Each alphabet lamp has a bottom casing, a top cover, an illumination circuit board, and a slide. The top cover is mounted on the bottom casing. The illumination circuit board is mounted in the bottom casing and between the top cover and the bottom casing. The illumination circuit board has an illumination component and a plurality of sockets. The slide is detachably mounted on the bottom casing. The top cover is located between the slide and the bottom casing. A pattern is formed on the slide. Because the slide of the alphabet lamp is detachable, the pattern on the alphabet lamp can be changed.

A stand for a touch screen device, including a base including at least two wheels, wherein the wheels are retractable within the base. The stand also includes a frame including a first end and a second end, attached by its first end to the base. Furthermore, the stand includes a support for the touch screen device, attachable to the frame at the proximity of the second end of the frame. The support includes means for rotating the support with respect to the frame and means for locking the support with respect to the frame. The stand also includes a battery and means for connecting the battery to the touch screen device.

An advertising medium includes a frame enclosing a traffic signal control cabinet. The frame includes opposing rails for each side of the cabinet with opposing inside surfaces of the rails including grooves extending longitudinally along the rail and spaced from each other. A light panel is carried within one groove near, yet spaced from, surfaces of cabinet walls. An advertising panel is carried within a second groove. The advertising panel is spaced from the light panel and on an opposite side from the cabinet wall. A clear protective panel is carried within a third groove and opposite an outer surface of the advertising panel. Tie rods extend between lock devices which are secured to the rails such that removing the frame from its position around the cabinet is prevented. As a result, advertising material may be secured to a traffic signal control cabinet without intruding upon or modifying the cabinet.

A display apparatus has a panel for receiving and/or displaying advertising material. The apparatus also includes a connector that is attachable to the panel, and a fastener for removably connecting the panel to a pipe of a beverage font. The fastener is removably attachable to the connector in two or more orientations.

Disclosed is a display module including a transparent display panel and a frame to fix a side of the transparent display panel, wherein the frame has a communication unit to receive data from the outside, a controller to process the received data and to output a drive command corresponding to the processed data and a display drive unit to drive the transparent display panel in response to the drive command from the controller. A display system includes a system body and a display module detachably mounted in the system body.
