Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backlight including an illuminated panel used for various notice boards or guide boards.

[0002]

2. Description of the Related Art Conventionally, a backlight including a light box and an illuminated panel is adapted to each application such as a backlight for a liquid crystal display element or a illuminated signboard without a light source. It has been created as a single function. On the other hand, the luminous material has been used as a material that luminesces sunlight or indoor illumination light and exerts its effect in a dark place. Accordingly, an illuminated panel or a light box having a light pocket for giving light to the luminous material and storing the luminous material in order to use the luminous material as one light source as in the case of a backlight as in the present invention has been made. Did not.

[0003]

SUMMARY OF THE INVENTION According to the present invention, a menu is printed on a phosphorescent plate in order to use a plate-like or film-like phosphorescent material (hereinafter referred to as a phosphorescent plate) as an alter ego of a backlight of a main body. A light-transmissive film on which a menu is printed is used by attaching it to a light storage plate, and the light is stored in a light storage plate that has a limited time during which it emits light, that is, a light storage space equivalent to a battery charger. It is trying to make a light pocket.

[0004]

As described above, the present invention provides a backlight having a light pocket which is necessary for developing a new application by using a phosphorescent plate as a substitute for a backlight of a main body. It is. For example, a back light (hereinafter, referred to as a decorative panel) made up of a decorative panel with a picture frame or a stand by decorating a photographic film, a printing film, or the like is used to decorate the interior of a store with dark interior lighting, and the decorative panel. Light pocket on the back of the
A luminous plate on which a menu is printed or a luminous plate with a film on which the menu is printed (hereinafter referred to as a luminous menu) is put into the luminous storage, and if necessary, the luminous menu is taken out from the light pocket and used. If the light can be stored back in the pocket, a menu that is always bright and easy to see can be obtained even in a shop with dark interior lighting. Also, without providing a decorative panel part, create a light pocket exclusively for luminous storage using a backlight exclusively for internal irradiation, put a lot of luminous menus inside and store them, and take out the luminous menu as necessary If used, the light-storing menu that is always bright and easy to see can be distributed to many customers and utilized. In this way, by using the light pocket to store light, a new use for the light storage plate can be opened.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The first invention uses a part of the light of the decorative panel to irradiate a light storage plate accommodated in a light pocket to store light. If necessary, the light storage plate can be used as an alternation of a light source or It is used as a phosphorescent menu. For example, on one side, a decorative panel containing a photographic film, and on the other side, a decorative panel provided with a light pocket made so as to obtain sufficient light to be stored by the light storing plate, and then storing the light in the light pocket. By taking out the board as needed and using it, and storing it in the light pocket until the next use, it is possible to obtain a copy of a bright light source during use, that is, a luminous menu which is always easy to see. In addition, the backlight can open and close the light storage plate from two directions by opening two end faces,
In addition, by assembling one unit back to back, a double-sided light emitting decorative panel having a light pocket can be provided.

The present invention does not limit the structure of the backlight that supplies light to the light pocket provided inside the decorative panel. Therefore, the number of light sources, the shape and number of light guide plates, and the mounting position such as one side or both sides may be determined as appropriate, and a single-sided backlight or diffusion plate using a light guide plate. A plurality of backlights of a type in which a light source is disposed immediately below the camera may be used. Further, a transparent plate may be used in place of the conventional diffusion plate in order to effectively use the light of the light source. That is, the present invention is to produce a decorative panel having a light pocket that supplies sufficient light for storing a light storing material or a light storing menu stored in the light pocket.

In a second aspect of the invention, one end or two end surfaces are opened to form a light-storing plate entrance, and the remaining surface is closed to form a light-storing-only light pocket having no light-emitting surface.
For example, the light-storing menu is a light-storing-only box that is used when the number and types of light-storing menus are too large to exceed the capacity of the light pocket of the decorative panel. Further, the above-mentioned light storage box can be attached to the back of a conventional decorative panel or a liquid crystal display panel, and used as a light storage box for a light storage menu or various light storage plates. Further, a conventional decorative panel is attached to the light pocket provided at the center back to back, or a liquid crystal display panel is attached back to the light pocket provided at the center back to back, and a double-sided display type provided with the above-mentioned light storage box is provided. Can be used as a decorative panel or a liquid crystal display panel.

The present invention does not limit the structure of the backlight used for the light pocket exclusively for storing light.
Therefore, the number of light sources, the shape and number of reflectors, and the mounting position such as one side or both sides may be determined as appropriate, and a single-sided or double-sided back light using a light guide plate may be used. A plurality of backlights in which a light source is arranged immediately below a light or a diffusion plate may be used.
Further, a transparent plate may be used in place of the conventional diffusion plate in order to effectively use the light of the light source. That is, the present invention is to create a light pocket dedicated to light storage, which supplies sufficient light enough to store light storage materials and light storage menus stored in the light pocket.

A third invention provides a large number of decorative panels or liquid crystal display panels, such as a panel in which three decorative panels or liquid crystal display panels are assembled in a triangle, or a panel in which four decorative panels or liquid crystal display panels are assembled in a square. A light pocket of a shape corresponding to each is provided inside a polygonal or circular decorative panel by assembling it, and the light storage plate that has stored light in the light pocket is extracted and used as a copy of the decorative panel or dark It is intended to be an explanation plate of a liquid crystal panel which is easy to see even in places.

The present invention does not limit the structure of the backlight as in the first embodiment. Therefore, the number of light sources, the shape and number of reflectors, and the mounting position such as one side or both sides may be determined appropriately.
Alternatively, a single-sided or double-sided backlight using a light guide plate, or a plurality of backlights in which a light source is disposed immediately below a diffusion plate may be used. Further, a transparent plate may be used in place of the conventional diffusion plate in order to effectively use the light of the light source.
That is, the present invention is to create a light pocket dedicated to light storage, which supplies sufficient light enough to store light storage materials and light storage menus stored in the light pocket.
