A light-emitting device includes: a balloon, a light source disposed outside the balloon; and an optical fiber that connects the balloon and the light source and propagates light emitted by the light source. At least one of the balloon and the optical fiber becomes luminous by the light emitted by the light source.

Disclosed are a method and system for controlling a display condition which is pre-written into a passive light board by a mobile device. A display status is pre-written into a passive light board which is not powered by electricity before, and a control application program loaded into the mobile device is provided for a user to input a brightness parameter and a color temperature parameter. The light board which is not powered by electricity before can carry out the presetting of the display condition, and related manufacturers can set the light boards quickly and easily after the light boards exit the factory, and the light boards can display according to the conditions in compliance with the brightness parameter and the color temperature parameter after the light boards are powered on.

A sign apparatus of the present disclosure includes a light source operable to emit light, a front panel having a front portion and a side portion, and a rear panel attached to the front panel and having a back portion, a side portion and a rim portion. The rear panel and the front panel define a cavity where the light source is housed. The side portion of the front panel extends between the cavity and the side portion of the rear panel, and the rim portion of the rear panel is configured to follow a contour of the front panel, extend beyond a periphery of the front panel, and have opaque properties.

The present disclosure discloses a forgery-proof label and a fabrication method thereof. The forgery-proof label includes a thin film battery and an OLED display unit operable to display a first preset pattern when being powered by the thin film battery. The forgery-proof label is easy to recognize and difficult to reuse.

A mark and sign illuminating device and system. The device is a device in which a transparent light guide layer (1203), a light reflecting layer (1204) and border rims (1251, 1252) are formed integrally. An LED illuminating light source LED1 and an LED illuminating light source LED2 are provided in the transparent light guide layer (1203). The reflective layer (1204) is provided with overlapping incidence of effective incident angles within the range of 360 degrees in the transverse direction and within the range of about 1 degree to about 179 degrees in the longitudinal direction, so that wide effective reflection angles and observation angles are formed. The advantage is that marks, signs and warning marks can be identified, seen and read more easily.

An insect trapping light is shown having a visible light housing, an electronic display screen, and an insect trapping housing. The display screen may be a television screen, picture display screen, movie display screen, computer monitor or display, or the like. The insect trapping housing has a bottom space configured to removably receive an insect bait tray that may be filled with an insect baiting substance to attract insects. The insect trapping housing and the visible light housing combine to form a UV light space or chamber therebetween. An adhesive board is slidably received and held in place upon the visible light housing surface facing the UV light chamber. The spacing between the insect trapping housing and the visible light housing defines the UV light chamber having open sides The UV light chamber also includes a matrix or array of UV lights or light sources.

Systems, kits and methods are disclosed which facilitate more dynamic and visually impactful backlighting of fabric panel displays. A perimeter frame assembly has a front edge, a rear edge, and a backlight cavity disposed therebetween. A front perimeter groove extends along the front edge. A display panel includes a flexible textile display substrate removably mounted in tension across the backlight cavity. A planar array of independently-activatable point light elements distributed in mutually-orthogonal X and Y directions is disposed within the backlight cavity at a gap distance from the display substrate. The gap distance is orthogonal to the X and Y directions. A controller is in data communication with the planar array for programmably controlling sequential activation and deactivation of the point light elements independently of one another. The display substrate may have a dye sublimated printed textile graphic thereon, and the point light elements may be white LEDs.

Disclosed herein are systems and methods for displaying illuminated images. In some embodiments a light box is capable of receiving a wide variety of images, which may be changed as desired by a user. The light box may be framed independently for wall hanging or display on a stand, or incorporated within or attached to pieces of furniture, including but not limited to beds, dressers, changing tables, book shelves, chests of drawers, toy chests, and the like. In various embodiments, the light box may include a dimmer, a timed dimmer, a motion sensor, and/or equipment for playing music or generating white noise. In certain embodiments, a single light box may be used, while in other embodiments a plurality of light boxes and/or digital picture frames may be used.

A three-dimensional artwork device that provides a three-dimensional appearance for providing visual interest. The three-dimensional artwork includes a base layer having an upper surface having artwork thereon. One or more spacers are positioned on the base layer, and one or more art layers are positioned on the spacers. The art layers overhang the edges of the spacers so that the spacers are not visible to an observer. Multiple spacers and art layers can be stacked to provide additional depth. A plurality of LEDs is positioned on the base layer, and are preferably positioned adjacent to the spacers so that the LEDs are not visible by an observer.

A lighting system includes a first light device having a housing; a suction means secured to a first end of the housing, the suction means being configured to removably secure the housing to a transparent structure; a light carried within the housing; and a power source conductively coupled to the light. The method includes securing the housing to the transparent structure; and directing light through the transparent structure with the light.
