Description

    The present invention relates to a display shelf installed in a store or the like.

  Conventionally, decorative plywood such as painted plywood and polyplywood has been used for shelf boards of display shelves installed in stores and the like. In such a display shelf, in order to improve the decorativeness of the display shelf, cosmetic printing is usually performed on the surface of a plywood or the like constituting the shelf board. However, there are many common decorative printing such as wood grain patterns and metallic paints, and these cannot be said to realize attractive and attractive display shelves that enhance customer attraction. It was.

  Therefore, a transparent plate-shaped light guide plate whose surface is subjected to light scattering treatment is used as a shelf plate, and a light source such as an LED is disposed on the small surface of the light guide plate to project light into the light guide plate and to scatter the light. There are known shelves that can shine the shelf board (see, for example, Patent Document 1).

Moreover, the shape is a flat light-emitting body of a substantially square shape of 5 to 600 mm square, preferably 50 to 100 mm. One EL element 2 may constitute a single light emitting panel. For example, as shown in FIG. 3, by providing 100 pieces of 10 mm square EL elements 2c (light emitting cells) in a lattice shape. One light-emitting panel may be configured. In the latter case, it is desirable to perform patterning of transparent wiring so that lighting is controlled on a cell basis. In this case, the driving method may be either an active type or a passive type.

  As shown in FIG. 4, the EL element 2 is formed by forming a light emitting portion 23 on a light-transmitting substrate 22 and covering the outside with a sealing material 24. Here, an example is shown in which the EL element 2 is configured as a single light-emitting panel, but in the plurality of EL elements 2c as shown in FIG. Except for this point, the basic configuration is the same. The light emitting section 23 is formed by sequentially laminating an anode 23 a made of a transparent conductive film, a light emitting layer 23 b having a light emitting function, and a light transmitting cathode 23 c on a substrate 22 in order. The sealing material 24 is made of a transparent material, and is covered so that a part of each electrode is exposed. The exposed portion of these electrodes is electrically connected to an electrode terminal (not shown) directly or via a lead wire. Connected to.

  The substrate 22 is made of a translucent glass such as soda lime glass or non-alkali glass, a translucent resin material, or the like, and is formed in a rectangular plate shape. In addition, you may form the light emission part 23 grade | etc., On the plate glass 11 (refer FIG. 2) which comprises the light emission shelf 3, and the plate glass 11 will be the substantial board | substrate 22 in this case.

The anode 23a is an electrode for injecting holes into the light emitting layer 23b, and an electrode material made of a metal, an alloy, a conductive compound, or a mixture thereof having a high work function is used. Preferably, the work function is 4 eV or more. Things are used. In particular, a light-transmitting conductive material such as ITO, SnO ₂ (tin oxide), or ZnO (zinc oxide) is preferable. The anode 23a is formed by depositing and patterning these electrode materials on the surface of the substrate 22 by a method such as a vacuum deposition method or a sputtering method.

  For the light emitting layer 23b, an organic fluorescent material capable of emitting desired white light is used. For example, anthracene, naphthalene, pyrene, tetracene, coronene, perylene, phthaloperylene, naphthaloperylene, diphenylbutadiene, tetraphenylbutadiene, coumarin, oxadiazole Bisbenzoxazoline, bisstyryl, cyclopentadiene, quinoline metal complex, tris (8-hydroxyquinolinato) aluminum complex, tris (4-methyl-8-quinolinato) aluminum complex, tris (5-phenyl-8-quinolinato) Aluminum complex, aminoquinoline metal complex, benzoquinoline metal complex, tri- (p-terphenyl-4-yl) amine, 1-aryl-2,5-di (2-thienyl) pyrrole derivative, pyran, quinacridone, rubu Emissions, distyrylbenzene derivatives, di still arylene derivatives, and compounds having a group consisting of these luminescent compound in a part of the molecular structure, the polymer material, mixed material of various fluorescent dyes are used. In addition, when one light emission panel is comprised by the several EL element 2c as shown in FIG. 3, a fluorescent substance may be selected suitably so that each EL element 2c may become the light emission color from which RGB differs. desirable.

  The light emitting layer 23b is formed by forming and patterning the above-described compound on the surface of the anode 23a by, for example, a vacuum deposition method. Note that the light emitting layer 23b may be a laminate of a plurality of different materials, and a buffer layer for adjusting the potential may be interposed between the plurality of layers.

The cathode 23c is an electrode for injecting electrons into the light emitting layer 23b, and is formed of a light-transmitting conductive material such as ITO, SnO ₂ , or ZnO, similarly to the anode 23a. The cathode 23c is also formed by the same method as the anode 23a.

May be provided to such an extent that does not spoil (not shown).

  Next, an operation example of the display shelf 1 will be described. Here, an example is shown in which the display shelf 1 is used in a store that handles apparel products such as clothes and bags. For example, as shown in FIG. 5, the control unit 4 (see FIG. 1) turns on the EL elements 2 of all the light-emitting shelf boards 3. If it carries out like this, the display shelf 1 will be especially conspicuous in a store, and a customer can be effectively attracted to the goods displayed on this display shelf 1. And if the light emission area | region of the light emission shelf 3 is made wide, the display shelf 1 will function also as a lighting fixture in a shop substantially. If the EL element 2 is completely turned off, the display shelf 1 can be used as a normal display shelf having a transparent shelf board.

  Further, the light emitting shelf 3 is configured so that the plurality of EL elements 2 arranged in a lattice shape can be individually controlled in a predetermined pattern, so that, for example, as shown in FIG. The light emitting area can be adjusted according to the size and arrangement of the product M. In particular, if the lighting of the store is set to be dark, the product M displayed on the transparent shelf board is illuminated as if it is lifted by light from below, and the customer attraction for the product M is increased. Further, if a light emitting panel is constituted by the above-described plurality of EL elements c (see FIG. 3) and they are individually controlled to be lighted, a finer effect can be achieved. Etc. can be displayed. In this case, the price of a product, a brand logo, etc. may be displayed.

  Moreover, you may make the EL element 2 of the location where the goods were put among the light emission shelf boards 3 light-extinguish. For example, if a product such as clothing that requires a relatively large display area is placed on the lit EL element 2, light is blocked by the product, resulting in a light emission loss. Therefore, by turning off the EL element 2 at the display position of the product, useless lighting can be reduced, energy saving can be achieved, and the product can be protected from the heat from the EL element 2.

  Furthermore, the customer's eye-catching effect can be enhanced by changing the light-emitting area of the light-emitting shelf 3 with time. Further, for example, a human sensor (not shown) may be provided on the support member 6 so that the predetermined EL element 2 is turned on when a customer approaches.

  As described above, the display shelf 1 according to the present embodiment includes the light-emitting shelf plate in which the plurality of EL elements 2 are arranged, and thereby emits light at any position of the shelf plate to enhance illumination that enhances the displayed product. can do. In addition, by individually controlling the lighting of the plurality of EL elements 2 according to a predetermined pattern, it is possible to further increase the customer attraction of products displayed on the display shelf 1.

  In addition, the EL element 2 may be arrange | positioned on the back surface (drawing on the upper surface on drawing) of the transparent shelf board 21 like the modification of the light emission shelf board 4 shown in FIG. More specifically, a flexible resin sheet 25 is used for the substrate of the EL element 2, and a plurality of light emitting portions 23 and sealing materials 24 (see FIG. 4) having predetermined dimensions are provided on the resin sheet 25. Thus, a so-called flexible EL element sheet 26 is prepared. The flexible EL element sheet 26 may be attached to the transparent shelf board 21 and used as the light emitting shelf board 3. If it carries out like this, the function similar to the display shelf 1 of this embodiment can be given to the existing display shelf which has glass shelf boards.

  Next, a display shelf according to a modification of the present embodiment will be described with reference to FIG. In the display shelf 1, one surface of the light-emitting shelf 3 is a mirror surface. Specifically, the mirror plate 27 is attached to any surface of the light emitting shelf 3. In the above-described embodiment, the EL element 2 is transparent, and the plate glasses 10 and 11 sandwiching the EL element 2 are also transparent. Therefore, the light from the light emitting unit 23 is emitted to both the upper surface and the lower surface of the light emitting shelf 3. The On the other hand, in the display shelf 1 according to the modification, since the mirror plate 27 is attached to any surface of the light emitting shelf 3, the light incident on the surface to which the mirror plate 27 is attached is reflected on the mirror plate. 27 and is emitted from the other surface. Therefore, it is possible to reduce the light emission loss and effectively illuminate the product. Normally, the mirror plate 27 is attached to the lower surface side of the light emitting shelf 3 so that light is emitted from the upper surface side of the light emitting shelf 3 on which the product is placed. As for the light emission shelf board 3, it is desirable to stick the mirror surface board 27 on the upper surface side. Moreover, the mirror surface plate 27 is not limited to the plate-shaped member as illustrated, and may be a sheet material that has been subjected to mirror surface finish coating.

  Next, a display shelf according to still another modified example of the present embodiment will be described with reference to FIGS. 9 and 10. In the display shelf 1, a through-hole 31 is formed at a substantially central portion of the light-emitting shelf 3, and the support member 6 is inserted through the through-hole 31. According to this configuration, products can be displayed on the light-emitting shelf 3 over 360 degrees with the support member 6 as the center, and the EL elements are partially lit to provide illumination in the store. Function. Therefore, if this display shelf 1 is installed in the center of the store, a particularly high customer attraction can be exhibited.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above-described embodiment, an example in which a plurality of EL elements 2 arranged in a lattice shape are individually turned on / off to change the light emission area of the entire light emission shelf 3 has been described. The dimming output of each of the EL elements 2 may be controlled. Further, by using the EL element 2 capable of emitting three colors of red, blue, and yellow, the controller 4 performs lighting control by combining these emission colors, for example, color rendering of the store space according to various situations. The sex may be changed. In the display shelf 1, for example, it goes without saying that the shapes and specifications of, for example, the light-emitting shelf 3 and the support member 6 are not limited to the illustrated examples.
