A hybrid photoluminescent display consumes little electrical power and provides for light emission/color in a desired color. The display includes a housing having openings forming a desired legend. White LEDs internal to the housing provide light for energizing photoluminescent material. A legend panel housed within the housing defines openings corresponding to the legend. Photoluminescent material is disposed within the openings of the legend panel. The photoluminescent material is selected to be energizable by light from the white light source, and to emit light primarily in a selected wavelength range corresponding to a desired legend color. A color is filter disposed adjacent the photoluminescent material on a side of the legend panel opposite the light source. The color filter is selected to selectively transmit substantially all light in the selected wavelength range, and to selectively not transmit substantially all light outside the selected wavelength range.

A suction lighting system may provide a plurality of suction cups that may attach to a surface and display an advertisement or a decorative facade. The suction lighting system may provide at least one suction cup that may be provided to attach to the surface and may emit light from one or more LEDs. The method may provide steps for advertising on or decorating a structure utilizing a set of suction light devices. The method may include searching for available advertising space and displaying the advertisement within the space.

A mattress age indicating device includes an enclosure and an indicating assembly contained within the enclosure. The age indicating device may be configured to present an indication related to the mattress's age and may be coupled to the mattress or other bedding or seating product.

An illuminating display window has a window pane and a graphic element including fluorescent material. The graphic element has a major surface facing forward and a perimeter surface extending transverse to the major surface. An electromagnetic radiation source is configured to emit electromagnetic radiation to the perimeter surface of the graphic element. The radiation includes electromagnetic radiation having a wavelength in a non-visible spectrum. The graphic element fluoresces in response to the non-visible radiation to transmit visible light to an observer in front of the window pane. To form the graphic element, fluorescent ink can be deposited on a panel in a predefined pattern or a fluorescent panel could be shaped to have a predefined shape.

An ornamental liquid display utilizing a silicone oil as the circulating fluid. A circulator moves the fluid such that it interacts with an effect surface, creating sensory interest. The fluid may be supplemented with various dyes, fragrances, and particles, and the implementation of the display may create visual and/or auditory interests by the motion of the fluid. The display may additionally use a purifier or filter to remove outside contaminants from the fluid.

Disclosed is a digital sign system and method of use thereof. The system includes a digital sign having a controller board having a microcontroller, a temperature sensor communicably coupled to fans or a cooling/heating unit, an ambient light sensor, a GPS unit, a radar, a communication module, and a power source, wherein the controller board is in communication with an LED panel or another display module for digitally outputting messages, further wherein the digital sign is mounted on a pilot truck to allow the pilot truck to relay messages to a transport truck and oncoming vehicles. The digital sign is in communication with a second GPS unit disposed on the transport truck so as to track the real-time location of the truck. The digital sign measures the distance between a transport and the digital pilot truck sign and displays the relative distances between the two on the digital message board. In operation, the digital sign is configured to automatically adjust its brightness so as to optimize its visibility while reducing glare to other drivers on the road.

There is disclosed a road sign plate comprising a base plate (2), a series of LEDs (4) arranged on said base plate and supply means associated to said series of LEDs in which, particularly, there is a first resin layer (1) laid on which covers, at least, the base plate (2) and a second resin layer (7) arranged over said first resin layer, wherein said second resin layer (7) is of a translucent material. This road sign plate is not expensive, features great capacity of mechanical strength and electric resistance and improved translucency properties.

A product display shelf, system and method are disclosed. The product display system includes a shelf unit having a back shelf portion and a front shelf portion. The back shelf portion includes a first connecting element for releasably attaching the back shelf portion to an electrically powered support member, and the front shelf portion includes a second connecting element for releasably attaching the front shelf portion to the back shelf portion. The front shelf portion can also include a body portion and a display panel connected to or integral with the body portion, suitable for displaying information to a user.

An intelligent light-supplementing LED system for message signs and traffic lights includes multiple optical lenses and LED units which are respectively provided behind each of the optical lens. The LED units include at least two LEDs connected in parallel; multiple LED units are connected in parallel to form a parallel system unit, or multiple LED units are connected in series to form a serial system unit. The parallel system unit is connected to a constant current power supply or a constant current circuit. The serial system unit is connected to a constant current power supply, a constant-voltage DC source, or a constant current circuit. So if an LED fails to light up, the total current that passes through the LED unit will have no or little change.

A luminous element holder for fastening to at least one body, includes a slot-like interior chamber, wherein, by means of at least one web protruding laterally into the interior chamber, the interior chamber is divided into a slot-like insertion chamber for receiving the at least one body and a receiving chamber, openly adjoining the insertion chamber, for at least one luminous element.
