DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-emitting road sign or traffic sign composed of a concrete structure provided with an EL light-emitting body, or various guide blocks, road boundary blocks, median strip blocks, wall materials, and the like. The present invention relates to a guide display, an interior material, a landscape material, and the like. The EL light-emitting concrete structure of the present invention is a concrete structure having excellent visibility and aesthetic appearance, and having a light-emitting display function having a high degree of freedom in shape, such as being able to form a curved surface as a light-emitting surface.

[0002]

2. Description of the Related Art Conventionally, a retaining wall block or a guard rail provided with a light reflecting plate or the like is provided on a sharp curve portion of a road or the like for ensuring safety. By shining, the presence of the curve can be confirmed even at night. However, in the configuration using the light reflecting plate, there is a problem that the light is not sufficiently reflected unless the vehicle approaches the curve, so that visibility from a distance is poor.
Further, the range illuminated by the light of the car is limited, and the illuminated range of the light moves as the vehicle travels, so that the light may not be properly irradiated on the reflector, which is very dangerous. Roads without streetlights, such as mountainous areas and suburbs, and roads with a small number of streetlights are dangerous because the center line of the road and the boundary line of the sidewalk are difficult to see at night. It was particularly dangerous if a storm occurred.

Therefore, it has been proposed to embed a luminous body in a retaining wall block provided on a boundary block (curbstone) or a sharp curve of a sidewalk. For example, JP-A-59-76304 discloses a retaining wall block using a light emitting diode as a light emitting body, and registered utility model No. 3036936 embeds an optical fiber cable provided with a light emitting diode (LED). It is described that the used concrete block is used as a roadway / sidewalk block.

[0004]

However, since LEDs emit light at a point, a large number of LEDs must be arranged to occupy that area in order to display information by emitting light in a certain area. However, there is a problem that the power connection becomes complicated and power consumption increases. Further, those using LEDs are not necessarily good in visibility because they are displayed by a group of point emission. Furthermore, since the LED display portion is formed by a mechanical arrangement, there is a disadvantage that the display function and the guidance function of the light emitting section are inferior.

According to the present invention, an EL luminous body which emits surface light is used as a luminous body, and the luminous portion is formed in a plurality of sections, symbols or characters, or punched shapes thereof, and the luminous body is made of a concrete structure. It solves the above-mentioned problems in the conventional light-emitting display type concrete by mounting it on the body and adapting it to a specific application.It is a concrete structure with good visibility and excellent display function and guidance function by the light-emitting part. To provide.

[0006]

That is, the present invention comprises a concrete structure having an electroluminescent light emitting panel (EL light emitting panel) mounted thereon, and a light emitting traffic sign, a road sign, a display panel or a display block, a road side wall block, The present invention relates to an EL light-emitting concrete structure used as a boundary block for a roadway or a sidewalk, a block for a median strip, or a wall material or an interior material forming a light-emitting portion of a retaining wall, an inner wall of a tunnel, or an outer wall of a structure. .

A preferred example of the EL light-emitting concrete structure according to the present invention is that the light-emitting portion of the EL light-emitting panel has a figure,
A control circuit that is formed in the shape of a symbol or a character, or a punched shape thereof, and that these shape portions are formed by light-emitting elements having different luminous colors or shades, or that switches the light emission of each portion stepwise. Are attached to the EL light emitting panel, and have a function of switching between multicolor display and light emitting portion.

In another preferred example of the EL light emitting concrete structure according to the present invention, an EL light emitting panel is mounted in a concave portion on the surface of the concrete structure with its light emitting surface facing inward. It is characterized by irradiation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. An EL light-emitting display concrete structure according to the present invention is a concrete structure having a display function provided with an EL light-emitting panel, wherein the EL light-emitting panel has a surface-emitting EL element light-emitting portion, and a front surface and a rear surface for protecting the light-emitting portion. , And preferably, the front surface is formed of a transparent and weather-resistant member. In addition, it is more preferable from the viewpoint of aesthetics if the outer surface is formed as a continuous outer surface integral with the surface of the concrete structure.

In general, an EL luminous body is formed of a sheet-like laminate, and has a structure in which an insulating layer is interposed between a transparent surface electrode layer and a back electrode layer with a phosphor layer interposed therebetween. Covered by film. EL used in the present invention
The light-emitting panel includes a surface light-emitting portion made of this EL light-emitting body, and a front portion and a back portion for protecting the surface light-emitting portion. The front part is formed of a transparent member so that the light emitting part is displayed outside. In addition, the front and rear parts protect the light-emitting part in an airtight manner, and are resistant to weather,
A material having water resistance, light resistance and the like is desirable. For example, the front part is formed of a transparent glass material or a resin material, and the back part is formed of a resin material or the like. The front part and the back part may be provided in close contact with the light emitting part, or formed in a case shape,
A structure in which a light emitting unit is housed therein may be used. Also,
In general, since the EL luminous body has flexibility, a flexible EL luminous panel can be obtained by forming the above-mentioned front and rear portions with a flexible material.

On the other hand, a recess having a depth corresponding to the thickness of the EL panel is provided on the surface of the concrete structure.
By sticking or embedding the EL light-emitting panel in the recess, the panel can be mounted so that the outer surface of the panel forms a continuous external surface integral with the surface of the concrete structure. Also, by utilizing the flexibility of the EL light emitting panel, a light emitting surface curved integrally with the curved surface of concrete can be formed. Here, the phrase “the panel surface portion forms an outer surface that is integrally continuous with the surface of the concrete structure” means that the panel surface surface forms the same plane that is substantially continuous with the surface of the concrete structure. There may be a slight step between the panel surface and the concrete surface.

The light emitting panel is preferably detachably mounted on the concrete structure. By providing the light-emitting panel detachably, it can be easily replaced or repaired. As detachable mounting means, for example, EL
Either the back surface of the light emitting panel or the panel mounting recess of the concrete structure is provided with a groove for engagement, and the other is provided with a ridge engaging with this groove. Alternatively, a means such as providing a screw hole for screwing in a panel mounting recess provided on the surface of the concrete structure can be used. The mounting means is not limited to such screwing or screwing.

[0013] In the EL light emitting display concrete structure according to the present invention, preferably, the surface light emitting portion of the EL light emitting panel is formed by a figure,
It is formed in the shape of a symbol or a letter, or a punched shape. By forming in this manner, a specific shape or a specific symbol or character can be displayed by light emission. As this specific structure, for example,
The EL light emitting element layer is formed in a shape of a figure, a symbol or a character, or a punched shape thereof. Alternatively, a light-emitting portion to be displayed may be made to emit light in these punched shapes by providing a shielding layer in the shape of a figure, a symbol, or a character on a surface layer laminated on the light-emitting layer, or a shield of a punched shape may be provided. A layer may be provided to emit light in the above shape. Further, the shape of a figure or the like may be divided into a plurality of portions, and specific information may be displayed by a change in each light emitting portion. Further, these light-emitting portions are formed in advance by light-emitting elements of different color tones or different shades of light emission, or a control circuit for switching the light emission of each portion stepwise is provided to change the color tone and shade of light emission. A display function can be formed.

Since the EL light-emitting display concrete structure of the present invention can display such specific shapes, figures, symbols, characters and colors, it is possible to display light-emitting road signs, traffic signs, guidance displays and guidance displays. It can be used as a concrete panel or concrete block. Conventional traffic signs and road signs have a structure in which the sign is attached to a support, so that they are easily damaged by a car collision or the like, and often cannot be used due to rust or peeling of paint.
According to the present invention, since traffic signs and road signs can be formed as a concrete structure, they are resistant to impact and do not cause problems such as rust and peeling of paint. In addition, since it is a self-luminous sign, the display is clear even at night or in a day with poor visibility, and has excellent visibility.

Further, since the EL light emitting display concrete structure of the present invention is made of concrete, it can be incorporated as a wall material or an interior material in a concrete retaining wall, an inner wall of a tunnel, and an outer wall of a structure. While forming the same continuous wall surface as the wall surface, a light emitting portion or a display portion can be formed on a part of the wall surface. By providing the retaining wall according to the present invention, for example, along a sharp curve or a shoulder of a road, the protective wall can be used as a sign for indicating a dangerous place. In the case where the present invention is applied to the inner wall of the tunnel or the wall of the structure, the guide guide sign or the sign of the emergency communication means can be used together with the wall.

Furthermore, the concrete structure of the present invention
It is suitable as a road material having a light emitting display function. That is, it is used as a road side wall block having a light emitting display function, a roadway or sidewalk boundary block, or a median strip block. These are used to clearly indicate the boundaries of the specific area.However, by applying the present invention, it is possible to form a high-visibility road environment with a clear display even at night or in places with poor visibility. Can be.

In addition, since the concrete structure of the present invention can form a unique lighting environment by its light emitting display function, it is suitable for landscape materials, monuments, etc. installed around parks, gardens, or buildings. The light-emitting display concrete structure of the present invention can be a self-luminous concrete structure that does not require an external power source by incorporating a solar cell or the like.

In the concrete structure of the present invention, in addition to the structure in which the light-emitting portion of the light-emitting panel to be used is mounted on the outer surface of the concrete structure, the light-emitting surface of the light-emitting panel is provided in the concave portion of the concrete structure surface. A so-called indirect light type structure in which the light emitting device is mounted inward and indirectly emits EL light can be used. Specifically, for example, a concave portion having a predetermined depth is provided on the surface of the concrete structure, and an EL light-emitting panel is mounted on the inner surface of the concave portion so that the light-emitting surface faces the other inner surface of the concave portion. It is formed so as to be reflected outward by the concrete surface in the recess. In this case, a transparent front cover (plate) that covers the recess is provided,
The outer surface (plate) may form an outer surface integral with the concrete surface. With this structure, the indirect light reflected by the EL light is emitted to the outside, so that an illumination environment that cannot be obtained by direct light can be formed.

The EL light-emitting concrete structure of the present invention comprises:
A solar battery or the like can be used as a power source, and is suitable for a case where the device is installed outdoors such as a traffic sign, a road sign, and a road boundary block. Note that a general power supply such as a power line may be used.
