Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a road traffic sign,
The present invention relates to a sign device used for railway signs and advertisements.

[0002]

2. Description of the Related Art In general, typical signage devices include road traffic signs installed on roads and railway signs such as a station name display panel and a time display panel in a railway. Also,
Neon signs installed on buildings such as buildings are also signs in a broad sense, and other commercial advertisements such as posters other than neon signs can also be called signs.

[0003] By the way, these sign devices are required to have good visibility at night. Therefore, some sign devices are conventionally provided with a lighting function.

For example, in the case of a road traffic sign, the front surface of the sign is subjected to a process of easily reflecting light, and a specially provided lighting device or a high beam of a headlight of a car is used to illuminate the road traffic sign from the outside and reflect the light. The light is made visible to drivers and pedestrians.

[0005] In addition, a translucent panel provided with a sign design is attached to a road traffic sign incorporating lighting means, specifically, a frame body incorporating lighting means such as a fluorescent lamp. In some cases, the contents of the sign can be visually recognized from the outside by transmitting the light of the built-in lighting means through the panel.

Further, a plurality of light emitting diodes (hereinafter, referred to as a plurality of light emitting diodes)
An LED is arranged to form a road traffic sign that displays traffic information such as traffic congestion and warning information for speed attention, in particular. Also, it is conceivable to form a sign design itself by arranging a plurality of LEDs having different emission colors. For example, in the case of a sign prohibiting vehicle entry, a red LED is arranged in a red portion, and entrances and lanes on a highway are arranged. , A green LED is arranged in a green portion.

On the other hand, a lighting method similar to that in which the above-described lighting means for a road traffic sign is incorporated is employed for a station name display panel, a time display board, or the like which is a railway sign.

In commercial advertisements, neon signs are often used, but there are other advertisements in which an advertisement signboard is illuminated by external lighting means.

[0009]

However, the above-mentioned conventional illumination using reflected light requires a special illuminating device, which is very large and expensive, so that the use of automobile headlights is problematic. However, when the driver turns the headlights on the low beam, the light from the headlights does not easily reach the road traffic signs at high altitudes, so it is difficult for the driver to recognize the road traffic signs and the effect as a road traffic sign is not sufficiently exhibited. .

When the road traffic sign incorporates lighting means such as a fluorescent lamp, the road traffic sign itself has a length of 2 to 2 mm.
Because it is relatively large, 3 m, the size of the fluorescent lamp used is inevitably large, and as a result, the entire road traffic sign with built-in lighting becomes large and heavy, making it extremely inconvenient to handle and supporting it. There is a problem that the structure becomes large.

Furthermore, when a large number of LEDs are arranged to form a road traffic sign, a large number of LEDs are required. In the case of a multi-color configuration, it is very difficult to obtain a colored LED that matches the color of the sign. In addition, there is a problem that the power supply for driving each LED becomes very large, so that it becomes very expensive. In addition, in the case of LEDs, when some of the many LEDs constituting the sign are damaged, there is also a disadvantage that the sign cannot be completely displayed. Moreover,
Since the brightness of currently marketed LEDs is not very high, even if the sign content can be confirmed by the luminescent color at night, it is almost impossible to confirm the sign content by the luminescent color due to the surrounding brightness in the daytime. There is.

On the other hand, in the case of lighting on a railway sign such as a station name display panel or a time display panel, there is a problem that it is structurally very large and heavy, making it difficult to handle. There is also a problem that it is limited to a specific place such as a pillar portion of a platform of a station or a beam on a ceiling.

Further, in the case of commercial advertisements, neon signs are effective in that they can be viewed even at night, but the contents that can be expressed by neon signs are very limited, so that the advertisement function cannot be fully exhibited. On the other hand, in the case where the advertising signboard is illuminated by an external illuminating means, there is a problem that the illuminating means becomes very large like the above-described road traffic sign.

Further, in the case of a commercial advertisement, there is a particular problem that the above-mentioned existing lighting means has a low design value and does not provide an excellent advertisement function.

An object of the present invention is to provide a sign device which is thin, lightweight, easy to handle, and can be installed in various places.

[0016]

In order to solve the above-mentioned problems, the present invention provides a sheet-like light emitting means comprising an electroluminescent element, and a character, a pattern, etc., which are predetermined when the light emitting means emits light. It is provided with a design film having a porosity, which is provided with a predetermined sign design to be exposed and is attached to the light emitting means, and a protective film covering the polymer of the light emitting means and the design film. Features.

According to such a configuration, since the light emitting means itself is in the form of a sheet, the entire sign device is very thin, and is thinner and lighter than a conventional device having a lighting function. Very easy to handle. Also,
Since the entire sign device is thin and light, the installation place is not limited to a place having a conventional pillar or the like, and the device itself can be easily attached to a wall surface or the like with an adhesive.

Further, the present invention is characterized in that the sign design is a design for a road traffic sign.

In this case, since the light emitting means is in the form of a single sheet made of an electroluminescent element,
Unlike the conventional case, the device does not become large-scale as in the case of illuminating with external illumination means. In addition, as a design film to be attached to the light emitting means, by appropriately combining partially colored, transparent, translucent, etc. according to the design, it is possible to visually recognize the contents of the sign by light illumination of the light emitting means at night. Needless to say, it is possible to sufficiently recognize the contents of the sign even in the daytime without emitting light.

Furthermore, the present invention is characterized in that the sign design is a design for a railway sign.

In this case, the entire signage device is thin, lightweight and easy to handle, and the installation location is not limited to the pillars of the platform of the station or the beams of the ceiling, and the signage device is installed by effectively utilizing the wall surface of the station. It becomes possible.

Further, the present invention is characterized in that the sign design is a design for a commercial advertisement.

In this manner, various advertisements are possible without being limited in the contents of advertisements as in neon signs. For example, the present invention can also be applied to signboards and posters in the form of paper or film. These signboards and posters are partially or wholly luminous, and the luminous means is determined by the relationship with the coloring of the design film and the design of the power supply. Due to the relationship with the driving power source such as intermittent driving, a very excellent advertising function can be expected.

Further, the present invention is characterized in that a power supply means comprising a solar cell is provided as a drive power supply for the light emitting means.

By doing so, the power supply means composed of a solar cell is charged in the daytime when there is no need to illuminate, and the light emitting means is driven at night using the charged power supply means, thereby saving energy. Can be.

Further, the present invention is characterized in that the polymer, the protective layer covering the polymer and the power supply are held by one holding means.

This makes it possible to provide a marker device with an integrated power supply, which makes it very easy to handle.

Is a lower electrode layer made of any of silver (Ag), carbon (C), and aluminum (Al), 2 is an insulating layer made of an electrically insulating material formed on the lower electrode layer 1, and 3 is an insulating layer 2, for example, zinc sulfide (Zn)
S), a light emitting layer formed by adding copper, silver, manganese or a fluoride of a rare earth element to form a light emitting center in a fluorescent substance such as cadmium sulfide (CdS); 4 is a transparent upper electrode layer; The lower electrode layer 1, the insulating layer 2, the light emitting layer 3 and the upper electrode layer 4 constitute a light emitting means 5 composed of an electroluminescent element made of ITO (indium tin oxide) or the like formed by being laminated on the layer 3. Have been. The light emitting means 5 composed of the electroluminescent element hardly generates heat even when driving for a long time.

In FIG. 1, reference numeral 6 denotes a design film, which is transparent PET (polyethylene terephthalate).
By jetting color ink on the film, a predetermined design is printed and formed, and is adhered to the upper electrode layer 4 of the light emitting means with an adhesive or the like.

Here, for example, in the case of the entry prohibition sign shown in FIG. 3, the red PET is formed by ejecting red ink onto a portion of a circular PET film which appears on a black background in the figure. It is adhered on the upper electrode layer 4 of the light emitting means 5 formed in the same circle as the film. Also,
In the case of the guide signs for the entrance notice and the exit notice of the highway shown in FIGS. 4 and 5, respectively, the green PET is formed by ejecting the green ink to a portion of the rectangular PET film which appears on a black background in the drawing. The rectangular PET film is bonded to the upper electrode layer 4 of the light emitting means 5 formed in the same rectangle as the PET film. However, a printing process necessary in relation to the emission color of the light emitting layer 3 is performed on the white background portion in FIGS. At this time, when it is not necessary to perform the printing process on the white background portion, it may be kept transparent.

Further, in FIG. 1, reference numeral 7 denotes a protective film, which is made of a moisture-proof polyethylene film. The light-emitting means 5 and the design film 6 adhered and polymerized thereto.
The light emitting means 5 and the design film 6 inside are formed so as to cover the entire polymer composed of

The light emitting means 5 is connected to a separately provided driving power supply (power supply means). At this time, the connection terminal of the light emitting means 5 with the power supply is processed as shown in FIG. It has been done. That is, as shown in FIG. 2, both the electrode layers 1 and 4 and the insulating layer 2 except for the light emitting layer 3 extend beyond the end of the design film 6, and the two electrode layers 1 and 4 and the insulating layer The extended portion 2 is further led out of the protective film 7 and is connected to a driving power supply by soldering or the like.

The driving power supply at this time is 100 V, 60 V
When a high-intensity is required as the luminance of the light-emitting means 5, a 6-Hz inverter (or an inverter circuit for converting a commercial alternating-current of 50 Hz (or 50 Hz) to about 400 Hz is used.
A circuit composed of an inverter circuit for converting into a high frequency alternating current such as 00 Hz to 3 kHz is used. Note that the frequency converted by the inverter circuit constituting the drive power supply is these four.
The frequency is not limited to 00 Hz or 600 Hz to 3 kHz.

Further, a solar cell may be combined with the driving power source. In this case, the solar cell is charged in the daytime when there is no need to illuminate, and the light emitting means 5 is driven at night using the charged solar cell. This makes it possible to save energy. At this time, the solar cell and the commercial AC may be used in combination.

If a design such as a station name display panel or a time display panel is applied to a PET film, a design film 6 on which a design for a railway sign is formed can be obtained.
If an advertisement design for a product, a company or various events is applied to the film, a design film 6 on which a commercial advertisement design is formed can be obtained.

Therefore, according to the above-described embodiment, since the light emitting means 5 itself has a sheet shape, the entire sign device becomes very thin, and is thinner and lighter than a conventional device having a lighting function. Of course, handling becomes very easy, and it goes without saying that installation work can be performed much easier than before, and it does not protrude on the wall of the building and hinders traffic of people and vehicles. Since the sign device can be adhered without the need, the installation place is not limited as in the related art.

Further, unlike the conventional case of illuminating with external illumination means, the device does not become large.

Further, the design film 6 adhered to the light emitting means 5 is made of transparent P by color printing according to the design.
Since the ET film is formed by applying translucent coloring, it is possible to visually recognize the contents of the sign by illuminating the light of the light emitting means 5 at night, and it is not necessary to emit light during the day. Also, it is possible to visually recognize the sign content from the color printed design, and it is possible to eliminate the inconvenience that the sign content cannot be visually recognized in the daytime as in the case where a large number of LEDs are used for a conventional road traffic sign.

In addition, since the sign device itself becomes thin, when used for commercial advertisement, it is possible to construct a poster using the sign device itself. If the drive power supply is designed so that the signboard attached to the sign device emits light partially or entirely, or the relationship with the coloring of the design film 6, and the light emission means 5 intermittently emits light at regular intervals. , It is possible to obtain a very good advertising function.

Incidentally, as another embodiment of the present invention,
As shown in FIG. 6, instead of pasting the design film 6 on the upper electrode layer 4, it may be pasted on the upper surface of the colored film 8 equivalent to the design film 6 having a predetermined design. The same effect as that of the embodiment can be obtained.

Further, as another embodiment, as shown in FIG. 7, a colored film 8 may be attached to the upper surface of the protective film 7.

In each of the above embodiments, the case where the sign design applied to the design film 6 is a road traffic sign, a railway sign, and a commercial advertisement design has been described. It is needless to say that the present invention is not limited to the above, and may be other artistic designs and the like.

Further, when the power supply means composed of a solar cell is used as the drive power supply as described above, the individual drive power supplies may be integrated into the marker device to be integrated (unitized), so that the handling is further improved. It will be easier.

Further, as a method of performing a predetermined sign design on the design film 6, the above-described embodiment employs PET.
Although the color printing on the film has been described as an example, it is needless to say that the present invention is not limited to this. In other words, a predetermined sign design is given so that predetermined characters, patterns, etc. are displayed at the time of light emission. Anything should do.

The present invention is not limited to the above embodiments, and various changes other than those described above can be made without departing from the spirit of the present invention.
