Abstract

(57) [Summary] [Purpose] Photos printed on plastic films,
Display devices that illuminate posters and the like from behind with fluorescent lights and the like are used for various purposes. However, it could not be made into a compact size that could be attached to a wall, and therefore was rarely used for general interior decoration. This invention provides a display device which can be used for wall hangings as well as a frame, by making it into a frame shape. [Structure] The small diameter fluorescent lamps 2 are continuously mounted in the outer frame 3. In order to apply the illumination light on the illumination screen plate 1 as uniformly as possible, the inner surfaces of the outer edge frame 3 and the base plate 4 are used as reflecting surfaces, and further, the base plate 4
An inclined reflector 5 and a partition reflector 6 are provided on the top. A display device having the illumination screen plate 1 of uniform brightness having the above structure and having a frame shape.

Description

[Detailed description of the device]     [0001]   [Industrial application] For the purpose of advertising, information display, viewing, etc., a illuminator such as a fluorescent lamp is lit in a box-shaped case. It is provided as a source, and photos, drawings, characters, etc. are printed or painted on the front of the case. Transparent or translucent glass plate, plastic plate, plastic film, etc. The function and structure to mount it and make it clear by the transmitted light of the illuminator from the inside The present invention relates to a display device having a structure.     [0002]   [Conventional technology] 2. Description of the Related Art Conventionally, a display device used for advertisement, guidance display, or viewing is illuminated by a fluorescent lamp or the like. Illuminator and reflector are installed in a box-shaped case, and the illumination light is received and the transmitted light is emitted. A screen is provided in front of the case, which can be used for lighting screens, illuminators, The plates are aligned and the lighting screen is primarily illuminated by the direct light of the illuminator. It was a structure that received light.     [0003]   [Problems to be solved by the invention] Due to its structural limitation, the conventional display device is not suitable for the lighting screen surface. There is no choice but to increase the depth, and to mount this display unit on the wall, It has a drawback that it is difficult to use because the protrusion is large. The present invention has been made to eliminate this drawback.     [0004]   [Means for solving problems] It is thick enough not to get in the way even if it is attached to the wall, and it is aesthetically pleasing. In order to realize a display device, the outer frame (3 ), And a small-diameter fluorescent lamp tube (2) is continuously installed. And the outer frame A surface composed of (3), the illumination screen plate (1), and the base plate (4) By providing a part of the inner surface of the panel excluding the lighting screen plate (1) as a reflective surface. Can be solved. On the other hand, when the area of the lighting screen plate (1) increases, this reflection The brightness of the surface of the lighting screen plate (1) is more Get dark. Therefore, the base between the base plate (4) and the lighting screen plate (1) is An inclined reflector (5) and a partition reflector (6) are provided on the base plate (4). This Here, the inclined reflection plate (5) is on a perpendicular line that stands on the surface center of the base plate (4). A polygonal cone or cone with one point as the apex and the base on the base plate (4) It is an inclined surface with the side surface of the body as a reflection surface, while the partition reflector (6) is a base plate. Stand vertically on the rate (4) and inclined reflector (5) and have both sides as reflective surfaces On the ridgeline of the partition plate when the inclined reflection plate (5) is the side surface of the polygonal cone, and On the extension of the base plate (4) and, if it is the side of the cone, It is provided on a plurality of bus bars and an extension line on the base plate (4). .     [0005]   [Action] By making a frame shape, the fluorescent lamp tube (2) with a small diameter is housed in the outer frame (3). And a structure that mainly illuminates the lighting screen plate (1) with reflected light The display device can be made thinner by setting. But the lighting screen In the case of a large display device where the area of the lean plate (1) becomes large, the outer frame The lighting screen plate (1) is composed of only the reflective surface on the frame (3) and the base plate (4). The brightness of the surface tends to be darker in the central part than in the peripheral part close to the fluorescent lamp (2). Remarkably appears. Therefore, an inclined reflection plate (5) and a partition reflection plate (6) are provided to The central portion is made lighter by the primary reflected light and the secondary reflected light, and the lighting screen plate (1 ) To make the brightness uniform. In addition, the brightness is adjusted by adjusting the position of each reflection surface. It is possible by adjusting the area, the area, the inclination angle and the like in advance.     [0006]   [Example] Example 1 FIG. 1 is a perspective view showing a first embodiment, and FIG. 2 shows a cross section thereof. (A) The outer frame of this rectangular frame type display device is the same as the base plate (4). Composed of an outer frame (3) surrounding it, and a lighting screen plate (1) To be done. The illuminating screen plate (1) allows the transmitted light to diffuse easily when it passes, so that the Translucent white plastic plate or frosted glass plate to soften the trust And so on. (B) The small-diameter fluorescent lamp tube (2), which is a light source for illumination, is placed in the outer frame (3). Install as continuously as possible with no gaps. (C) At the part between the lighting screen plate (1) and the base plate (4), An inclined reflector (5) and a partition reflector (6) each having a reflecting surface are provided. here, The inclined reflector (5) has a point on the center of the surface of the base plate (4) as its apex. A quadrilateral similar to the splat (4), with the base sharing the diagonal line It has the side of the quadrangular pyramid on the rate (4) as an inclined surface. The projection plate (6) is on the ridge of the quadrangular pyramid and its extension, and the inclined reflector (5) and the base It is a partition plate that stands vertically on the plate (4). (D) Base plate (4), lighting screen plate (1), and outer frame ( Except for the lighting screen plate (1), all the surfaces in contact with the space surrounded by the surface of 3) are Let it be the shooting surface. (E) Printed plastic film (7) on the lighting screen plate (1) On top of that, to protect the print plastic film (7), Cover the light cover plate (8) and fix it tightly. Due to this structure, The sticky film (7) can be freely replaced. (F) Fluorescent lamp ballast and accessory parts (9) necessary for lighting the fluorescent lamp Mounted on the rate cover (12), the inclined reflector (5) and the base plate (4) Store in the space between. The fluorescent lamp starting tube (10) is a fluorescent tube (11) and the fluorescent lamp tube socket (11). In addition, although the first embodiment shows an example of a quadrangular frame shape, a polygonal shape such as a pentagon or a hexagon may be used. It goes without saying that the rectangular shape can be implemented in the same manner. .     [0007] Example 2 FIG. 3 is a perspective view showing the second embodiment. This embodiment is the same as the embodiment 1 except that the inclined reflector (5) and the partition reflector (6) are mounted. In an example in which the positions are different, the diagonal line of the base of the quadrangular pyramid forming the inclined reflector (5) is The base plate is parallel to the outer periphery of the base plate (4), and is otherwise the same as that of the first embodiment. Have the same structure.     [0008] Example 3 FIG. 4 is a perspective view showing the third embodiment. This embodiment is an example of an elliptical frame shape, and a circular shape is also included in this example.     [0009]   [Effect of device] The display device obtained in this way is compact and can be used for wall hangings. We have realized a frame-shaped display device that is thick enough not to cause any problems. Since it can be used in dark places such as, waiting room, hospital room, etc. It can be expected to have a wide range of uses as interior decoration.
