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.

The invention relates to an illuminable emblem, in particular for a motor vehicle, which is simple and inexpensive to produce and which permits easy identifiability in darkness.

Framing member for use in mounting and displaying a SEG product.

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 light-emitting housing is disclosed. The light-emitting housing includes a light-emitting module and a housing. The light-emitting module includes a light guide plate and at least one light-emitting unit. The light guide plate includes an upper surface, a lower surface, and a plurality of dot regions, the dot regions are located on the lower surface, and the at least one light-emitting unit provides a plurality of light beams incident to the light guide plate. The housing is disposed above the light-emitting module and located on the upper surface of the light guide plate, and the housing includes at least one transparent region. Some of the light beams emitted by the at least one light-emitting unit are reflected through the dot regions and penetrate the upper surface of the light guide plate and the at least one transparent region. In this way, from the outside of the housing, the light beams penetrating the at least one transparent region can be observed, and a visual effect that a specific position on the housing emits light is generated.

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 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.

A self-generated lighting device, including: a frame, light source, solar cell, display panel, light guide plate, light reflecting plate, power control unit, and power storage device, wherein the power control unit controls electric power supplied to the light source and includes at least commercial electric power. The power storage device includes a power storage battery that stores electricity from the control unit, and supplies the electric power stored to the light source. The light source emits light energy toward a confronting side from one end side of an installation area in a frame, and the light guide plate guides the light energy emitted toward the display panel, and the light reflecting plate reflects the light energy toward the display panel, the light energy being guided toward a bottom surface portion of the light guide plate. The solar cell absorbs light energy of both direct and reflected light to generate electricity.

The invention relates to an illuminable emblem, in particular for a motor vehicle, which is simple and inexpensive to produce and which permits easy identifiability in darkness.
