An illuminated decorative panel comprises a slab composed at least partly of substantially transparent material, a decorative element associated with the slab, lighting device/unit/component/structure of the slab comprising at least one emitting device of at least one light wave, wherein the slab comprises at least one housing compartment of the emitting device formed along at least one stretch of at least one side of the slab.

Provided here are mobile way-finder signs having changeable panels that are internally illuminated. Internal illumination may be caused by battery-powered LED light bulbs. The sign may include a base, an inner frame, an outer frame, a changeable panel, and a retainer. The sign may include a power toggle switch and interior LEDs and wiring within the inner or outer frames. The sign may include a rechargeable battery pack located under the base in a snap-in holder, and heavy-duty black polyurethane wheels.

Modular lighted display panel assemblies are disclosed that are used to provide modular lighted signage in various applications. The modular lighted display panel assemblies may be linked in a serialized fashion in certain implementations shown herein. In one particular implementation described herein, modular lighted display panel assemblies are linked to provide digital signage on a series of server racks. The techniques described herein allow implementation of some panels without the additional cost and complexity of power modules and/or lighting modules.

A display unit for a passage control device, having a housing that has a front side, a rear side and an encircling circumferential side connecting the front side and rear side to one another. A display surface is integrated in the front side of the housing. The housing has an optical signaling apparatus that consists of front and rear light bands that are able to be actuated by a computing unit of the passage control device. The front light strip is arranged between the front and circumferential sides and the rear light strip is arranged between the rear and circumferential sides such that the front light strip is visible in a plan view of the front side and the rear light strip is visible in a plan view of the rear side.

A lightboard system providing the multiple advantages required by presenters to audiences. Wheels support and render mobile a base. Supported by the base, a frame defines an opening and includes pairs of vertical struts and corresponding vertical tubes, the tubes sliding along the struts in a telescoping movement to raise and lower the frame height. A clear screen is fixed within the opening; the height of the screen is adjusted as the frame telescopes. The screen has a front face displaying content from presenters and an opposing rear face, and induces paths for and scattering of light to highlight the content. A dimmable light source is embedded in the frame and illuminates the screen. Attached to a telescoping mount on the frame, a video camera is directed toward the rear face, streams or records the content to create images, and automatically flips the images for viewing by audiences.

A display device includes a display plate, a micro light source, a first reflecting element and a second reflecting element. The display plate has a pattern. The micro light source emits a light beam. The first reflecting element is arranged beside a first side of the display plate. A first portion of the light beam is reflected by the first reflecting element. A second portion of the light beam is transmitted through the first reflecting element. The second reflecting element is arranged beside a second side of the display plate to reflect the light beam. The light beam is repeatedly reflected by the first reflecting element and the second reflecting element, so that a multiple-luminous effect of the pattern is provided.

A system and method for controlling amount of light emitting from an illuminating screen including: a frame defining a space, a screen mounted onto a front side of said frame, a back plate mounted onto a back side of the frame, opposite the front side, at least one light source and a concealing element. The at least one light source is positioned within the space defined by the frame and is configured to illuminate the screen. The concealing element is located inside the space defined by the frame and is configured to block light from illuminating the screen. The amount of light emitting through the screen is controlled by a ratio between the area of the concealing element positioned in a section located between the at least one light source and the screen, and the total area of the section.
