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.

A display apparatus includes: a substrate; a strip-like light source placed at ends in a width direction of the substrate; and a light guide plate mounted in front of the substrate. A display medium is disposed in front of the light guide plate. The substrate includes a main body and a pair of edge plates that cover the front surface of both ends in the width direction. Light source mounts formed separately to the substrate and the edge plates have a strip-like light source mounted thereupon and are fixed inside the insertion channels. The light guide plate is mounted with both ends inserted inside the insertion channels so that light from the strip-like light source is incident from end surfaces of the light guide plate.

A light distribution method for an advertising lamp box and an advertising lamp box are disclosed. The light distribution method comprises a step of edge lighting and a step of middle lighting, comprising: lighting from an inner wall of a frame to the middle, and lighting on two sides in the middle of the inner portion of the advertising lamp box. With the same effect as conventional lighting tools, the light distribution method of the present invention has the advantages of environmental friendliness, firmly fixed lenses which are not easy to fall off, high structural strength enough to be applied to large lamp boxes, low labor cost of mounting, and so on.

A digital human development platform can enable a user to generate a digital human. The digital human development platform can receive user input specifying a dialogue for the digital human and one or more behaviors for the digital human, the one or more specified behaviors corresponding with one or more portions of the dialog on a common timeline. Scene data can be generated with the digital human development platform by merging the one or more behaviors with one or more portions of the dialogue based on times of the one or more behaviors and the one or more portions of the dialog on the common timeline.

The present disclosure discloses a signboard assembly and a fully transparent solar LED luminous signboard. The signboard assembly comprises: a U-shaped sealing ring, a patterned reflective film, a light-diffusing plate, a light-guiding plate, an LED light bar, a white reflective film, a back plate, a signboard bracket, and a control box. The full-transparent solar LED luminous signboard includes a solar power supply assembly and the signboard assembly as described above. The present invention adopts side light emitting principle, wherein light is guided through the light-guiding plate, is reflected by the reflective film, and is homogenized by the light-diffusing plate, so that the whole signboard is finally illuminated uniformly. The problem that the traffic sign is difficult to identify is solved.

An electrical device for a vehicle includes a housing having an upper portion and a lower portion. An upper light source attaches to the upper portion and a light guiding element attaches to the upper portion to receive the upper light from the upper light source and direct outgoing light in a substantially uniform direction. A display attaches to the upper portion to receive the outgoing light for illumination of the display. A lower member couples with the lower portion. A lower light source attaches to the lower member. A collimator attaches to the lower member to receive incoming light from the lower light source and change directions of the incoming light to a collimated beam. A lens element attaches to the lower portion to direct the collimated beam at a target.

A self-contained illuminated sign for mounting on a vehicle is disclosed. The sign includes a front panel, a rear panel situated opposite and substantially parallel to the front panel in spaced relation therefrom to define a space therebetween, and a light source comprising a plurality of LEDs. The light source is positioned between the front and rear panels and is configured to emit light that emanates from the front panel. The front panel is thus backlit to display indicia. A system for supporting a self-contained illuminated sign on a vehicle is also disclosed. The system includes the sign and a separate mounting frame mountable on a vehicle. The mounting frame is configured to removably receive the sign and, when the sign is received in the mounting frame, to surround a perimeter of the sign while permitting visibility of the front display area. Related methods are also disclosed.

A digital human interactive platform can determine a contextual response to a user input and generate a digital human. The digital human can convey the contextual response to the user in real time. The digital human can be configured to convey the contextual response with a predetermined behavior corresponding to the contextual response.

A reflective-ink lighting assembly includes a light transferring medium, a reflective-ink marking in the light transferring medium, and a light source adapted to insert light into the light transferring medium. In a lit state, light from the light source propagates through the light transferring medium by total-internal reflection. As propagated light reflects off the reflective-ink marking, some light exits through a facade of the light transferring medium to produce an illuminated marking. In an unlit state, the reflective-ink marking remains visible due to ambient light reflecting off the reflective-ink marking.

The invention relates to an illuminable display element, in particular for a vehicle, which display element comprises a planar cover (1). The planar cover has a visible side (10), a rear side (11), and at least one opening (14). The display element also comprises at least one graphic element (2), which is provided and/or formed on the visible side (10) of the cover (1), and a lighting means (3), which is used to illuminate the opening (14). The graphic element (2) is at least partially surrounded by the at least one opening (14) in such a way the graphic element (2) can be at least partially peripherally illuminated by the light of the lighting means (3). The cover (1) comprises at least one elevation (12) extending upward, within which the graphic element (2) is arranged above the at least one opening (14), and/or the cover (1) comprises at least one recess (13) extending downward, within which the graphic element (2) is arranged below the at least one opening (14).
