Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting display member that emits light to display characters, arrows and the like.

[0002]

2. Description of the Related Art Conventionally, an emergency light has been used as an emergency guide display when the light is turned off, for example, in an office building or a hotel. This emergency light is a plastic box that displays the evacuation route and is equipped with an electric light that is connected to an emergency power source that is different from the normal power source. By doing so, the evacuation route can be clearly displayed even in the dark.

[0003]

However, although the above emergency light can clearly display the evacuation route at the time of power failure, it has the following problems and is not necessarily suitable. In other words, the emergency light device must place the electric light in a semi-transparent plastic container on which guide signs such as arrows are written,
There is a problem that the structure is complicated and a special emergency power supply is required. Therefore, there is a problem that the device is large and the installation place is limited.

The present invention has been made to solve the above problems, and an object thereof is to provide a light emitting display member which has a simple structure and can be used at any place.

[0005]

In order to achieve the above object, the invention of claim 1 is to store a light energy from the outside world, and to radiate the stored energy to the outside world as a light; A shield layer provided around the phosphorescent material layer for preventing leakage of the phosphorescent material to the outside, and a part or the whole of the shield layer is made of a light transmissive material, characterized in that The gist of the light emitting display member is.

A second aspect of the present invention provides a light emitting display member according to the first aspect, characterized in that the plurality of phosphorescent material layers and a shield layer are laminated. Further, claim 3
The invention provides a light emitting display member according to claim 1 or 2, wherein the surface of the phosphorescent material layer or the shield layer is provided with a display layer made of characters, symbols, or figures.

Here, it is preferable that the light emitting display member is in the form of a sheet having flexibility because the method of use is easy and the place of use is not limited. A material having flexibility is suitable as the material of the shield layer, and for example, a transparent or translucent processed synthetic resin such as vinyl or polyethylene can be used.

[0008]

According to the invention of claim 1, the energy of the light received from the outside is stored in the light storing material layer, and the stored energy is radiated to the outside as light. Further, the shield layer provided around the phosphorescent material layer prevents the phosphorescent material from leaking to the outside. Here, since the shield layer is partially or entirely formed of a light transmitting material that transmits light, the light from the light storing material layer is emitted to the outside through the shield layer.

In particular, it is preferable to stack a plurality of light-emitting display members and stack a plurality of light-storing material layers and shield layers, since a large amount of light is emitted and the light emission lasts for a long time. Furthermore, when a display layer such as letters is formed on the surface of the phosphorescent material layer or the shield layer, the letters and the like stand out clearly because the surroundings of the letters and the like emit light, making it easy to display even in dark surroundings. You can check the contents.

[0010]

Next, a light emitting display member according to an embodiment of the present invention will be described with reference to the drawings. In the figure, the vertical and horizontal scales are changed in order to clearly show the state of each layer. Figure 1
As shown in the cross section in (A), the light emitting display member 1 of the first embodiment.
Is a sheet-like flexible member, and is formed in the shape of an arrow indicating a direction, for example, as shown in FIG.

The light emitting display member 1 has a phosphorescent material layer 3 containing a phosphorescent material in the center thereof, and shield layers 5 made of a transparent film such as polyethylene are formed on both sides of the phosphorescent material layer 3. In addition, the side end portion 7 of the phosphorescent material layer 3 is shielded by the shield layer 5 that has entered and the applied adhesive agent so that the phosphorescent material does not leak out. It should be noted that one surface of the light emitting display member 1 is coated with an adhesive to form an adhesive layer 9
The surface of the adhesive layer 9 is pasted with a seal 11 that is peeled off during use.

The light emitting display member 1 is manufactured by cutting or punching from a material 13 formed in a roll shape as shown in FIG. And this light emitting display member 1
When using, the seal 11 is first peeled off, the adhesive layer 9 is pressed against a predetermined display position, and the entire light emitting display member 1 is attached. Light-emitting display member 1 attached in this manner
Is not particularly noticeable when there is light in the surroundings, but once the surrounding light disappears, light is emitted from the phosphorescent material layer 3 through the transparent shield layer 5 to perform the display.

As described above, the light emitting display member 1 of this embodiment is
Since it can be displayed clearly even in the dark, it is a suitable guide display when electricity is suddenly turned off in the event of a power failure. Also,
Since no special emergency power source is required unlike the conventional emergency light, there are advantages that the device configuration is simple, the cost is low, and the life is long.

Further, since the periphery of the phosphorescent material layer 3 is sufficiently shielded, the phosphorescent material does not leak to the outside and can be safely used even when the phosphorescent material is harmful. In addition, there are few restrictions on where it can be used. Not only can it be used as a guide for emergency evacuation routes, but it can also be placed as a guide near equipment such as switches, breakers, and telephone boxes. It can be used in various places where it is easy to hit, such as the corner of a desk placed in a building such as a hotel.

Next, the light emitting display member of the second embodiment will be described. As shown in FIG. 3, the light emitting display member 2 of the present embodiment.
1 is a laminate of a plurality of phosphorescent material layers 23 and a plurality of transparent shield layers 25, and a double-sided tape 27 is attached to the bottom surface thereof.

Therefore, since the luminous material layer 23 is laminated on the light emitting display member 21, a large amount of light is emitted and the display is easy to see even in the dark. It can also emit light for a long time. Further, the double-sided tape 27 on the bottom surface has an advantage that it can be easily attached at any place.

Next, the light emitting display member of the third embodiment will be described. As shown in FIG. 4, the light emitting display member 3 of the present embodiment.
Reference numeral 1 is used, for example, to display the position of a switch, and is a rectangular shape in which a plurality of switch portions are punched out to form a plurality of windows 33.

Therefore, when the light emitting display member 31 is attached to the periphery of the switch, there is an effect that the entire plurality of switches can be clearly shown. next,
The light emitting display member of the fourth embodiment will be described. As shown in FIG. 5, the light emitting display member 41 of this embodiment has a display layer 42 formed of characters formed on the surface of the light emitting display member 41. Since the display layer 42 is formed of light-shielding ink, tape, or the like, when the surroundings become dark, it appears that the surroundings of the display layer 42 emit light and the characters appear to be clear, and the instruction content is clearly displayed. There is an advantage that you can check. The display layer 42 is a transparent shield layer 43.
It may be formed on either the front surface or the back surface.

It is needless to say that the present invention is not limited to the above embodiment and can be carried out in various modes without departing from the easiness of the present embodiment.

[0020]

As described above, according to the light emitting display member of the first aspect, the energy accumulated in the luminous material layer is radiated through the transparent shield layer, so that the surroundings become dark due to a power failure or the like. In this case, it is possible to clearly display the guidance. Further, since the shield layer is provided around the phosphorescent material layer, even if the phosphorescent material is harmful, it is possible to prevent danger without leaking. Furthermore,
It has a simpler construction than conventional emergency lights, so it can be easily installed at any place, has low cost, and has a long life.

In particular, when a plurality of light emitting display members are laminated and a plurality of phosphorescent material layers and shield layers are superposed, a large amount of light is emitted, and further, light emission lasts for a long time, which is preferable. In addition, when a display layer such as characters is formed on the surface of the light-storing material layer or the shield layer, the periphery of the characters or the like emits light, so that there is an advantage that the display content can be easily confirmed.
