One container system includes a transparent display, a projector for providing image data on the display, and a floor defining part of a watertight cavity. The display is non-perpendicularly angled from horizontal and has proximal and distal ends. And a closure device is provided for use with a watertight container. The closure device is configured to selectively seal an opening in the watertight container and includes coupling structure (a plug, a flange, and/or threading) for selectively coupling the closure device to the watertight container to seal the opening. The closure device further includes non-transitory computer memory, at least one sensor, and a processor in data communication with the memory and the at least one sensor.

A method of making suspended lighting fixtures that includes the use of flexible sheets of optically transmissive material, LED strips, and a linear heat-dissipating structure. The method comprises providing a first flexible sheet having a first major surface, an opposing second major surface, and a first edge having a first light input surface. A pair of flexible sheets of an optically transmissive material are provided, each having an edge with a light input surface. A first LED strip and a second LED strip are provided along with a linear heat-dissipating structure having a first channel and a second channel. The LED strips are positioned within the respective channels and attached to the body of the linear heat-dissipating structure. The edges of the flexible sheets are positioned within the respective channels and in proximity to the respective LED strips. The flexible sheets may be bent to a curved shape.

A display device includes a light source irradiating excitation light and a window glass for a vehicle, such as a windshield, capable of emitting visible light through incident radiation of the excitation light, and allows the window glass for a vehicle to emit the light so as to display a message toward an outside of the vehicle by irradiation with the excitation light.

An electronic price and/or product display device (2), which comprises a reflective screen (21) for displaying information, and a signalling device (28) for signalling an internal state or a state change of the display device (2) by superimposing said state or state change in a visually perceptible manner directly in the viewing direction of the screen.

A high efficiency traffic sign includes a retroreflective film and a diffuser film. The retroreflective film is located between the body of the traffic sign and the diffuser film so as to form an indication face. The traffic sign is located higher than a road and the indication face faces coining vehicles on the road. A projection light source module is located on one side of the road and emits a light beam toward the traffic sign and the light beam covers the indication face. The light beam passes through the diffuser film and reaches retroreflective film. The light beam is then reflected and passes through the diffuser film again, the diffuser film changes the reflective path of the light beam which passes through the diffuser film to form a diversified light beam to allow the drivers of the coining vehicles on the road to see the traffic sign clearly.

A suspended lighting fixture for direct/indirect lighting including a pair of curved sheets which are joined by a linear heat-dissipating structural element and cooperatively forming a trough-shaped structure configured to be suspended with a downward orientation using one or more suspension elements. The lighting fixture further includes a linear light source with one or more linear arrays of light emitting diodes (LEDs) optically coupled to light input edges of the curved sheets, a linear heat-dissipating structural element joining curved sheets, and an opaque elongated housing at least partially enclosing the structural element, light source, and the light input edges.
