A traffic sign board easily identifiable during day and night is provided. The traffic sign board which is easily identified at night includes a flickering operation of a backlight installed inside a frame, and easily identified by a driver during day even on a secluded country road or a deserted road due to flickering of light emitting diode (LED) light projected to a front side through a reflective sheet while the backlight is switched off.

The present invention relates to A selection panel (1) for a beverage dispensing device comprising a front window (2) having at least one display zone (3a) designed for displaying a product information label, at least one light source for illuminating the product information label arranged in the display zone (3a) of the front window (2), a reflector means (6) designed for reflecting the light emitted by the light source towards the display zone (3a) of the front window (2), wherein the light source is arranged outside of the contours of the respective display zone (3a).

Non-emergency illumination apparatus (10) arranged in use to mark a location of an article, fixture or fitting in an aircraft cabin, the apparatus including: an emitting layer (2) including a photoluminescent material, the photoluminescent material emitting visible light in a first region of the electromagnetic spectrum in response to excitation by light from a second region of the electromagnetic spectrum, different to the first region; and a protective layer (6) overlying the emitting layer, the protective layer transmitting light from the first and second regions of the electromagnetic spectrum, wherein the non-emergency illumination apparatus is constructed and arranged to be placed in proximity to an article, fixture or fitting, such that the apparatus marks the location of the article, fixture or fitting when excited by light from the second region of the electromagnetic spectrum. The illumination apparatus can comprise a carrier matrix. The illumination apparatus aids location of items such as headphone sockets and power sockets in low lighting conditions so calming passengers.

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 light-emitting display system has an alignment mechanism to align or angle light-emitting tiles of the display. A first tile connects to a second tile by joining a first clamp portion on the first tile with a second clamp portion on the second tile. In an implementation, the alignment mechanism includes a replaceable angle adjustment insert that is inserted into at least one of the clamp portions, such as the first clamp portion. When the first and second clamp portions are joined, a surface of the second clamp portion presses against the insert and a desired angle between the first and second tile is formed. The insert can have any angle so that any desired angle can be formed between the first and second tiles.

A light guide system includes a substrate with multiple light sources connected to the substrate. Multiple zones are individually positioned each proximate to one of the light sources. Each of the multiple zones includes a translucent area back-lit by energizing one of the light sources. A polymeric material is applied onto individual pairs defined by one of the multiple light sources and one of the multiple zones. The polymeric material after subsequent curing defines a light guide for each of the pairs for transmission of light generated by the light source of each pair. A reflective coating is applied onto the at least one external facing surface of the light guide, the reflective coating defining a material different from the polymeric material.

Provided is a side light-emitting type display device having a frame member. The side light-emitting display device having a frame member includes a display assembly configured to guide light to a side surface of the display assembly while displaying an image using light emitted from light sources; a transparent frame member which is configured to surround and fix the display assembly and through which the light guided to the side surface of the display assembly is transmitted; and a side display member provided on a side surface of the transparent frame member, and configured to display information of the image using the light guided to the side surface of the display assembly.
