Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a road traffic sign,
The present invention relates to a lighting sheet used for a railway sign, a commercial advertisement, and the like, a guidance display device using the same, and a level crossing circuit breaker.

[0002]

2. Description of the Related Art In general, representative display devices include road traffic signs installed on roads and railway signs such as station name display boards and time display boards in railways. A neon sign installed in a building such as a building is also a guidance display device in a broad sense, and other commercial advertisements such as posters other than the neon sign are considered to correspond thereto.

[0003] In these guide display devices, good visibility at night is also required.
2. Description of the Related Art Conventionally, a guidance display device has some illumination function.

[0004] For example, in the case of a road traffic sign, a front surface of the sign is subjected to a process of easily reflecting light, and a specially provided illuminating device or a high beam of a headlight of a vehicle is used to illuminate the road traffic sign from outside and reflect the light. The light is made visible to drivers and pedestrians.

[0005] In addition, a light-transmissive panel on which a character such as a sign is provided is provided on a road traffic sign having lighting means built therein, specifically, a frame body having lighting means such as a fluorescent lamp built therein. In some cases, the contents of the sign can be visually recognized from the outside by transmitting the light of the mounted and 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.

[0007] In the case of a license plate of a vehicle, the license plate is usually illuminated from the outside with a light source for illuminating the license plate provided on the vehicle so that the license plate can be recognized even at night. Recently, for example, as described in JP-A-10-81179, etc.
A license plate incorporating lighting means has also been proposed, and the license plate itself emits light, so that visibility at night is improved.

On the other hand, a lighting method similar to that of the above-mentioned conventional one in which lighting means for a road traffic sign is incorporated is employed for a station name display panel, a time bulletin board and the like which are railway signs.

[0009] Commercial advertisements have conventionally used neon signs transformed into characters or the like. Recently, however, advertising signs have been built in external lighting means or in a transparent or translucent body. Light sources illuminated by illumination means are often used.

[0010] Further, the crossing barrier for level crossings usually forms a stripe pattern in which yellow and black colors are alternately arranged on the outer surface of a pole made of bamboo, aluminum or synthetic resin, so that attention is paid to pedestrians and drivers of vehicles. However, there is a problem that visibility is reduced at night or during rainfall, and it becomes difficult to check the armature of the circuit breaker. Therefore, improvement in visibility at night or during rainfall is desired.

Therefore, as described in Japanese Patent Application Laid-Open No. 5-305870, a light beam having an incident angle of a certain angle or more with respect to the film surface is totally reflected on the inner surface of the arm tree made of a transparent or translucent hollow rod, It has been proposed to arrange a transparent light-transmitting film having a fine prism structure (retroreflection) for transmitting other light rays, and to arrange a light source at the base of the arm tree. To do
The visibility is improved even at night or during rain.

[0012]

However, in the case of a conventional road traffic sign, the illumination by the reflected light described above
Special lighting equipment is required, which is very large and expensive, and even when using the vehicle's headlights, when the driver turns the headlights on a low beam, the light from the headlights can be used in high-altitude road traffic. Drivers have difficulty recognizing road traffic signs because they are difficult to reach,
The effect as a road traffic sign has not been fully demonstrated.

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.

Further, when a road traffic sign is formed by arranging LEDs on one surface, a large number of LEDs are required, and in the case of a multi-color configuration, it is very difficult to obtain a colored LED matching the color of the sign. In addition, since the power supply for driving each LED becomes large, there is a problem that it becomes very expensive. In the case of an LED, a large number of LEDs constituting a sign are used.
If some of them are damaged, there is a disadvantage that the contents of the sign cannot be completely displayed. Moreover, since the luminance of currently marketed LEDs is not very high, even if the sign content can be confirmed by the luminescent color at night, the sign content by the luminescent color can hardly be confirmed due to the surrounding brightness in the daytime. There is also a problem.

On the other hand, with a license plate, in the case of external illumination using a conventional illumination light source, the illumination tends to be non-uniform, and it may be difficult to recognize the license at night. On the other hand, when illuminating from the inside by the illuminating means built into the license plate substrate, some uniform illumination can be expected,
Although the visibility at night is improved, a new problem arises in that the license plate substrate becomes thick due to the built-in lighting means.

By the way, as described in Japanese Patent Application Laid-Open No. 9-30325, a predetermined character or the like is punched out on a character substrate having a built-in illuminating lamp to form a character hole, and the character hole is formed from a translucent material. It has also been proposed to protrude and fix a flesh character and provide a retroreflector on at least the top of the flesh character so that the vehicle number can be recognized at night either by internal or external lighting. However, since it is necessary to incorporate an illuminating lamp in the character substrate and punch out characters, there is a problem that the character substrate also becomes thick, and a complicated punching operation is required, resulting in poor productivity.

In addition, in the case of lighting on railway signs such as a station name display panel and 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.

On the other hand, 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 with neon signs are very limited and complicated patterns cannot be expressed, so that the advertising function is not sufficient. Can not be demonstrated. On the other hand, in the case where the advertising signboard is illuminated by the external lighting means, there is a problem that the lighting means becomes very large like the above-mentioned road traffic sign.

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

In the case of a crossing barrier for level crossing, as described in the above-mentioned Japanese Patent Application Laid-Open No. 5-305870, when a cross is illuminated from the inside, a special transparent or translucent rod is used as a bar constituting the cross. In addition, since the light source is located at the base of the arm tree, light hardly reaches the tip side of the arm tree, and there is a problem that the illumination becomes uneven and the improvement in visibility is limited.

[0021] An object of the present invention is to provide a thin, lightweight, easy-to-handle lighting sheet with excellent visibility, a guide display device using the same, and a level crossing circuit breaker. .

[0022]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a sheet-like light-emitting member comprising an electroluminescent element, and a sheet-like recursive member attached to a light-emitting surface of the light-emitting member.

According to this configuration, since the sheet-like light-emitting member made of the electroluminescent element and the retroreflective member are provided, the illumination light from the inside of the light-emitting member is transmitted through the retroreflective member. While the pattern of the design film is exposed, the illumination light from the outside at a certain angle or more is totally reflected by the retroreflective member, and the reflected light causes the pattern of the design film to be exposed.

Therefore, regardless of whether the light emitting member emits light or not, the pattern of the design film can be exposed by internal illumination and external illumination, and the pattern of the design film can be externally exposed at night or day. Can be clearly recognized.

Furthermore, since the light emitting member itself is in a sheet shape, the entire lighting sheet is also very thin, and is thinner and lighter than a conventional one having a lighting function.
The handling becomes very easy, and the installation place is not limited to the place where there is 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 in the guidance display device using the above-mentioned lighting sheet, the pattern of the design film is a pattern such as a character or a pattern for a road traffic sign.

According to such a configuration, a thin and lightweight lighting sheet is used, and the design film is provided with a pattern such as a character or a pattern for a road traffic sign such as an exit guide of a highway, thereby handling the product. It is possible to provide a road traffic sign that is very easy to install and that can clearly recognize the pattern for the road traffic sign from outside either at night or during the day by internal and external illumination.

According to the present invention, in the guide display device using the above-mentioned lighting sheet, the pattern of the design film is a pattern such as a character or a pattern for a license plate of a vehicle.

According to such a configuration, the thin, lightweight lighting sheet is used, and the design film is provided with characters such as characters for a license plate, a design, etc., so that handling, installation, and processing are very easy. In addition, it is possible to provide a license plate of a vehicle that can be clearly recognized from the outside regardless of nighttime or daytime by internal illumination and external illumination.

Thus, it is possible to provide a railway sign capable of clearly recognizing a pattern for a railway sign from the outside regardless of daytime.

Further, the present invention is characterized in that, in the guide display device using the above-mentioned lighting sheet, the pattern of the design film is a pattern such as a character or a pattern for commercial advertisement.

According to such a configuration, by using a thin and lightweight lighting sheet and applying a design for commercial advertisement to the design film, handling and installation are very easy.
In addition, the contents of the advertisement can be clearly recognized regardless of nighttime or daytime by the internal illumination and the external illumination. Further, since the pattern for commercial advertisement applied to the design film can be easily changed, various advertisements are possible without being limited in the advertisement content as in the conventional neon sign. For example, a lighting board can be used by attaching a lighting sheet to a signboard or a paper or film-like poster. The signboard or the poster itself is partially or entirely illuminated, and the relationship with the coloring of the design film, the power supply, etc. Due to the relationship with the driving power supply such that the light emitting member is driven intermittently by the design of the above, a very excellent advertising function can be expected.

The present invention also provides a level crossing circuit breaker using the above-mentioned lighting sheet, wherein the lighting sheet is attached to a long arm at predetermined intervals, and the design film is formed in a single color. It is characterized by having.

According to such a configuration, a thin and lightweight lighting sheet is used, and for example, a lighting sheet of a yellow and patternless design film is provided in the yellow portion of the yellow and black color arrangement portions of the arms of the circuit breaker. By sticking, it is possible to provide a level crossing circuit breaker capable of clearly recognizing a lighting sheet portion stuck to a crosspiece from outside at night or day by internal and external illumination.

Further, since the lighting sheet itself emits light, no special member such as transparent or translucent is required for the crosspiece.
Moreover, a uniform lighting effect can be obtained even at the tip of the arm. In addition, if a continuous character, for example, the character “CAUTION” at the crossing is applied to the design film of each lighting sheet to be pasted, one character at a time or a kanji at one character or at least one character or two or more characters at the same time is called “CAUTION at the crossing” Since the characters are displayed by the respective lighting sheets, an effect that the visibility of the arm tree is further improved can be expected.

(First Embodiment) A first embodiment of the present invention will be described.
An embodiment will be described with reference to FIGS.
However, FIG. 1 is a sectional view, and FIGS. 2 to 5 are explanatory views of an application example.

In FIG. 1 showing the structure of the lighting sheet according to this embodiment, reference numeral 1 denotes a lower electrode layer made of any of silver (Ag), carbon (C), and aluminum (Al); The insulating layer 3 made of an electrically insulating material and formed on the insulating layer 3 forms a luminescent center in a fluorescent substance such as zinc sulfide (ZnS) and cadmium sulfide (CdS) formed on the insulating layer 2. A light emitting layer 4 to which copper, silver, manganese, a rare earth element fluoride or the like is added, and 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 member 5 made of an electroluminescent element, which is made of TO (indium tin oxide) or the like. The light emitting member 5 composed of the electroluminescent element hardly generates heat even when driving for a long time.

In FIG. 1, reference numeral 6 denotes a retroreflective member. For example, a retroreflective member having a well-known configuration as described in JP-A-7-218708 or JP-A-10-97208 can be used. is there. As a characteristic feature of the retroreflective member 6, the incident light having a certain angle or more with respect to the incident surface is totally reflected, and the other incident light is transmitted. Some of the rays emitted from 5 are reflected and some are transmitted,
Similarly, light rays emitted from an external light source (for example, sunlight or other lighting means) of the retroreflective member 6 are reflected or transmitted, so that illumination from the inside and illumination from the outside become possible. It is.

Further, in FIG. 1, reference numeral 7 denotes a design film, which is formed by spraying color ink on a transparent PET (polyethylene terephthalate) film to form a predetermined design, thereby forming an upper electrode layer of the light emitting member 5. 4 is adhered by an adhesive or the like.

Here, as an example of a road traffic sign as a guidance display device, in the case of the entry prohibition sign shown in FIG. 2, red ink is ejected on a portion of a circular PET film which appears on a black background in the figure. And adhered to the upper electrode layer 4 of the light emitting member 5 formed in the same circular shape as the circular PET film. In addition, in the case of the guidance display of the entrance notice and the exit notice of the expressway shown in FIGS. 3 and 4 which are other examples of the road traffic sign, a rectangular P
A predetermined pattern is formed by spraying green ink on a portion of the ET film that appears on a black background in the figure, and is formed on the upper electrode layer 4 of the light emitting member 5 formed in the same rectangle as this rectangular PET film. Adhered to. However, FIG.
4 to a white background portion in FIG.
A necessary printing process is performed in advance in relation to the emission color of the light emitting layer 3. 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 8 denotes a protective film, which is made of a polyethylene film having moisture resistance, and covers the light emitting member 5, the retroreflective member 6, and the whole of the design film 7 which is adhered and polymerized thereon. Package) to protect the light emitting member 5, the retroreflective member 6, and the design film 7 inside.

By the way, the light emitting member 5 is connected to a separately provided driving power source (power supply means). At this time, the connection terminal of the light emitting member 5 with the power source is processed as shown in FIG. It has been done. That is, as shown in FIG. 1, both the electrode layers 1 and 4 and the insulating layer 2 except for the light-emitting layer 3 extend beyond the ends of the retroreflective member 6 and the design film 7. The extended portions of the insulating layers 1, 4 and the insulating layer 2 are further led out of the protective film 8, and are connected to the terminals + and-of the 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 member 5, a 6 Hz (or 50 Hz) commercial AC is converted into an inverter circuit that converts the commercial alternating current to about 400 Hz.
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 member 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.

Further, when the present invention is applied to a vehicle license plate as shown in FIG. 5, a design film 7 may be provided with a vehicle number character or numeral pattern and then mounted on a reinforcing frame. No need to punch out large numbers, and because it uses thin lighting sheets,
The entire license plate does not become thicker than the conventional type with built-in lighting, and is very easy to handle and produce.

In addition, when a design such as a station name display panel or a time display panel is applied to the design film 7 as a guide display device, a railway sign on which a pattern such as a character or a pattern for a railway sign is formed can be obtained. . In addition, if a design for the advertisement of a product, a company or various events is applied to the design film 7 on the PET film, it is possible to obtain a guidance display device in which patterns such as characters and designs for commercial advertisement are formed.

Therefore, according to the first embodiment,
Illumination light from inside by the light emitting member 5 is reflected by the retroreflective member 6
, The pattern of the design film 7 is exposed, while the illumination light from outside having a certain angle or more is totally reflected by the retroreflective member 6, and the reflected light causes the pattern of the design film 7 to be exposed. Therefore, regardless of whether the light emitting member 5 emits light or not, the pattern of the design film 7 can be exposed by the internal illumination and the external illumination, and the pattern of the design film 7 can be displayed at night or day. It can be clearly recognized from outside.

The use of the retroreflective member 6 makes it possible to clearly recognize the pattern of the design film 7 from the outside regardless of whether it is nighttime or daytime under internal and external illumination. As in the case where a large number of LEDs are used, the inconvenience of not being able to visually recognize the contents of the sign due to the malfunction of some LEDs can be eliminated, and the patterns that can be applied to the design film 7 are extremely diverse. A variety of road traffic signs can be realized without any color restrictions.

Furthermore, when the present invention is applied to a license plate of a vehicle, the substrate does not become thicker as in the conventional built-in lighting type, and the work of punching out characters is not required. Without the need for clear recognition from the outside.

On the other hand, in the case of a railway sign, a thin and lightweight lighting sheet is used, and the design film 7 is provided with a character such as a station name or a timetable, or a pattern for a railway sign, a design, etc. This makes it possible to use the wall surface of the station effectively and install it, and it is possible to clearly recognize the display contents for the railway sign regardless of night or day by internal and external illumination.

When used for commercial advertisement, a poster can be constructed by itself by applying an advertisement pattern to the design film 7 of the lighting sheet.
A poster having such a structure, or a conventional signboard with an advertising sign attached to a signboard is partially or entirely caused to emit light, the relationship with the coloring of the design film 7 is devised, or the light emitting member 5 is used. If the drive power supply is designed so that light emission is intermittently performed at regular intervals, it is possible to obtain an excellent advertising function and advertising effect.

Further, since the light emitting member 5 itself is in a sheet shape, the entire lighting sheet is also very thin, and is provided with a guide display device such as a road traffic sign, a license plate, a railway sign, and a commercial notice having a conventional lighting function. Even when compared, it is thin and lightweight, making it very easy to handle, and the installation location is not limited to the place where there is a conventional pillar, etc., and the device itself is easily attached to the wall etc. with adhesive can do.

(Second Embodiment) A second embodiment of the present invention will be described with reference to FIG. However, this embodiment is an example in which a lighting sheet is used for a level crossing circuit breaker, and the configuration of the lighting sheet in this embodiment is the same as that of the above-described first embodiment. I will explain.

As shown in FIG. 6, the lighting sheet 12 is attached to the long arm 11 at a predetermined interval at a position corresponding to the yellow part of the yellow and black color arrangement of the arm of the circuit breaker.
At this time, the design film 7 of the lighting sheet 12 has no pattern and is colored yellow. In addition, arm arm 11
Is preferably made of, for example, a hollow aluminum material. In consideration of the weight, a hollow aluminum pole whose diameter decreases toward the tip may be added. The hollow aluminum material may be not only circular in cross section but also square.

In the case of such a structure, the thin and lightweight retroreflective member 6 of the lighting sheet 12 makes the lighting sheet portion adhered to the crosspiece by the internal illumination and the external illumination regardless of nighttime or daylight from the outside. Will be able to recognize
It is possible to provide a crossing barrier for a railroad crossing that is easily visible to vehicles and pedestrians.

Further, since the illumination sheet 12 itself emits light, a special member such as a transparent or translucent member for the arm is not required unlike the conventional art, and even the tip of the arm is substantially uniform with other portions. A lighting effect can be obtained.

If the design film 7 of each lighting sheet 12 to be affixed is given a continuous character, for example, the character "Caution", one character at a time or one or two or more hiragana characters at a time, Since the letters "attention to level crossings" are displayed by the lighting sheets 12, the visibility of the crosspiece 11 is further improved.

As another embodiment of the present invention, as shown in FIG. 7, instead of pasting the design film 7 on the retroreflective member 6, it is equivalent to the design film 7 having a predetermined coloring and pattern. May be attached to the upper surface of the protective film 8, and in this case, the same effect as in the above-described embodiment can be obtained.

Further, as another different embodiment, as shown in FIG. 7, a design film 7 is provided with only a pattern such as a character or a pattern without being colored, and a predetermined area is formed on a predetermined area on the upper surface of the protective film 8. A colored film 16 may be attached.

In each of the above-described embodiments, the case where the design applied to the design film 7 is a pattern for a road traffic sign, a vehicle license plate, a railway sign, and a commercial advertisement has been described. The patterns are not particularly limited, and may be, of course, artistic patterns or similar patterns.

In the case where 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 incorporated into the guide display device to be integrated (unitized). It becomes even easier.

Further, as a method of applying a predetermined pattern to the design film 7, color printing on a PET film has been described as an example in the above embodiment, but it is needless to say that the present invention is not limited to this.

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