Description

この発明は発光表示装置に関し、特に夜間には文字や図形などの図柄が浮き上がって見え、昼間にはその図形が太陽光によって鮮明に視認できるようにした装置に関する。   The present invention relates to a light-emitting display device, and more particularly to a device in which characters, graphics, and the like appear floating at night, and the graphics can be clearly seen by sunlight in the daytime.

例えば、地震、火災、台風などの緊急時には住民を非難場所や建造物の外に安全かつ確実に誘導するための誘導標識が大切である。   For example, in the event of an emergency such as an earthquake, a fire, or a typhoon, guidance signs are important for safely and reliably guiding residents out of condemned places and buildings.

従来この種の誘導標識は導光板の表面に文字や図形などの図柄を印刷加工などによって形成する一方、導光板の裏面全面に光の反射板を設け、導光板の側面から例えばＬＥＤの光を入射させ、導光板の反射板で反射させ、夜間において図柄を明瞭に視認できるようにした誘導標識が知られている（特許文献１、特許文献２、特許文献３）。   Conventionally, this type of guide sign is formed on the surface of the light guide plate by characters, graphics, etc. by printing, etc. There are known guidance signs that are made incident and reflected by a reflector of a light guide plate so that the design can be clearly seen at night (Patent Document 1, Patent Document 2, and Patent Document 3).

特開２００５−２６５９６６号公報JP 2005-265966 A 特開２００５−３８７７１号公報JP 2005-38771 A 特開２００３−４１５３３号公報JP 2003-41533 A

しかし、従来の誘導標識では夜間には有効であるものの、昼間には導光板の表面から入射した光が乱反射されてしまい、誘導の図柄が見にくいという問題があった。   However, although the conventional guide sign is effective at night, the light incident from the surface of the light guide plate is irregularly reflected during the day, and it is difficult to see the guide pattern.

本発明はかかる問題点に鑑み、夜間には文字や図形などの図柄が浮き上がって見え、昼間にはその図形が太陽光によって鮮明に視認できるようにした発光表示装置を提供することを課題とする。   In view of such problems, it is an object of the present invention to provide a light-emitting display device in which symbols such as letters and figures appear to be lifted at night and the figure can be clearly seen by sunlight in the daytime. .

そこで、本発明に係る発光表示装置は、文字及び／又は図形からなる図柄が発光素子の光によって視認できるようにした発光表示装置において、側面には光入射部が設けられ、表面には視認される図柄が形成され、裏面には側方からの光を前方に反射する光の反射図柄が形成された透光性の導光板と、該導光板の側面の光入射部に設けられ、上記導光板の側面から内方に向けて光を入射させる発光素子と、上記導光板の背後に配置され、上記導光板の表面から入射した光を前方に反射する裏板と、を備えたことを特徴とする。   Therefore, the light-emitting display device according to the present invention is a light-emitting display device in which characters and / or graphics can be visually recognized by the light of the light-emitting element. A light-transmitting light guide plate having a light reflection pattern for reflecting light from the side forward, and a light incident portion on a side surface of the light guide plate. A light emitting element that allows light to enter inward from the side surface of the light plate, and a back plate that is disposed behind the light guide plate and reflects light incident from the surface of the light guide plate forward. And

本発明の特徴の１つは導光板の表面に図柄を設け、導光板の裏面に光の反射図柄を設けて導光板側面から入射した発光素子の光を反射図柄で前方に反射するとともに、導光板の背面に裏板を設けて導光板表面から入射した光を裏板で前方に反射するようにした点にある。   One of the features of the present invention is that a design is provided on the surface of the light guide plate, a light reflection design is provided on the back surface of the light guide plate, and the light of the light emitting element incident from the side surface of the light guide plate is reflected forward by the reflection design. A back plate is provided on the back surface of the light plate so that light incident from the surface of the light guide plate is reflected forward by the back plate.

これにより、導光板側面から入射された発光素子の光は反射図柄で反射されて導光板を発光させるので、夜間には導光板表面の図柄が発光素子の光によって浮き上がって明瞭に視認することができる。   As a result, the light of the light emitting element incident from the side surface of the light guide plate is reflected by the reflection pattern and causes the light guide plate to emit light, so that the design on the surface of the light guide plate is lifted by the light of the light emitting element at night. it can.

また、太陽光が導光板表面から背面に向けて入射すると、裏板で導光板の表面に向けて反射されるので、導光板の図柄は裏板の色彩中に浮かんで見え、裏板の色彩が例えば白色などの場合には昼間において図柄が白色をバックに鮮明に見える。   In addition, when sunlight enters from the surface of the light guide plate toward the back, it is reflected toward the surface of the light guide plate by the back plate, so the design of the light guide plate appears to float in the color of the back plate, and the color of the back plate In the case of white, for example, the design looks clear with the white background in the daytime.

図柄を鮮明に視認する上で、導光板の図柄を半透光性又は不透光性とし、光の反射図柄を表面の図柄の背後に位置して表面の図柄と同一の大きさでかつ同一の形状に形成するのがよい。   In order to clearly see the design, the design of the light guide plate is made semi-translucent or non-translucent, and the light reflection design is located behind the design on the surface and is the same size as the design on the surface. It is good to form in the shape of.

また、上記では導光板の表面に視認されるべき図柄を形成したが、導光板と裏板との間に図柄を形成しても発光素子の光及び太陽光によって同様に明瞭に視認できる。   Further, in the above description, a symbol to be visually recognized is formed on the surface of the light guide plate. However, even if a symbol is formed between the light guide plate and the back plate, it can be clearly clearly recognized by the light and sunlight of the light emitting element.

すなわち、本発明に係る発光表示装置は、文字及び／又は図形からなる図柄が発光素子の光によって視認できるようにした発光表示装置において、側面には光入射部が設けられ、裏面には側方からの光を前方に反射する光の反射図柄が形成された透光性の導光板と、該導光板の側面の光入射部に設けられ、上記導光板の側面から内方に向けて光を入射させる発光素子と、上記導光板の背後に配置され、上記導光板の表面から入射した光を前方に反射する裏板と、上記導光板と裏板との間に介在され、視認されるべき図柄が打ち抜き形成され、着色された透光性のカッティングシートと、を備えたことを特徴とする。   That is, the light-emitting display device according to the present invention is a light-emitting display device in which characters and / or graphics can be visually recognized by the light of the light-emitting element. A light-transmitting light guide plate having a light reflection pattern for reflecting light from the front, and a light incident portion on a side surface of the light guide plate, and transmitting light from the side surface of the light guide plate to the inside. A light emitting element to be incident, a back plate disposed behind the light guide plate and reflecting light incident from the surface of the light guide plate forward, and interposed between the light guide plate and the back plate, should be visually recognized It is characterized by comprising a translucent cutting sheet in which a pattern is punched and colored.

このカッティングシートの図柄は反射図柄の背後に位置して反射図柄と同一の大きさでかつ同一の形状に打ち抜き形成されるのがよい。   The design of the cutting sheet is preferably formed behind the reflective design by being punched into the same size and the same shape as the reflective design.

図柄は導光板の表面に形成されていればよく、例えば半透光性シート又は不透光性シートを図柄の形状に切り取ったカッティングシートを導光板の表面に貼り付けることによって構成されることができる。また、図柄は半透光性又は不透光性の塗料を用いて導光板の表面に塗布し又は印刷加工することによって構成されることもできる。   The design only needs to be formed on the surface of the light guide plate. For example, the design may be configured by pasting a cutting sheet obtained by cutting a translucent sheet or a non-translucent sheet into a design shape on the surface of the light guide plate. it can. The design can also be configured by applying or printing on the surface of the light guide plate using a semi-translucent or non-translucent paint.

光の反射図柄は導光板の裏面を図柄と同一の形状にレーザー加工又はブラスト加工することによって形成することができる。また、光の反射図柄は半透光性又は不透光性の塗料を用いて導光板の裏面に塗布し又は印刷加工することによって構成されることもできる。   The light reflection pattern can be formed by laser processing or blasting the back surface of the light guide plate into the same shape as the pattern. The light reflection pattern can also be configured by applying or printing on the back surface of the light guide plate using a semi-translucent or non-translucent paint.

導光板の材料は光を透過し得る透明材料であれば特に限定されず、例えばポリカーボネートやアクリルなどのプラスチック材料やガラスなどを採用することができる。発光素子はＬＥＤなどの公知の素子を採用することができる。   The material of the light guide plate is not particularly limited as long as it is a transparent material that can transmit light. For example, a plastic material such as polycarbonate or acrylic, glass, or the like can be used. A known element such as an LED can be adopted as the light emitting element.

カッティングシートの材料は半透光性又は不透光性があればよく、例えばプラスチック材料や紙を使用することができる。また、裏板の材料は光を反射できればよく、例えばプラスチック材料やガラスを使用することができる。   The material of the cutting sheet may be semi-translucent or non-translucent, and for example, a plastic material or paper can be used. Moreover, the material of a back plate should just reflect light, for example, a plastic material and glass can be used.

以下、本発明を図面に示す具体例に基づいて詳細に説明する。図１ないし図３は本発明に係る発光表示装置の好ましい実施形態を示し、これは誘導標識に適用した例である。図において、誘導標識１０は導光板１１の下側に裏板１２を重ね、その周囲を金属製、例えばアルミニウム製のフレーム１３が囲んで構成されている。   Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 3 show a preferred embodiment of a light emitting display device according to the present invention, which is an example applied to a guidance sign. In the figure, the guide sign 10 is configured such that a back plate 12 is stacked on the lower side of the light guide plate 11 and a metal frame, for example, an aluminum frame 13 surrounds the back plate 12.

導光板１１は例えばガラス板を用いて製作され、その表面には図柄１５が貼り付けられ、図柄１５は着色した透光性又は不透光性の薄い軟質プラスチックシートから文字や図形の形状に切り抜いたカッティングシートを用いて製作されている。例えば、「矢印」「５００ｍ」及び「津波図形」は青色、「津波避難場所」「人間」及び「Ｔｓｕｎａｍｉ Ｅｖａｃｕａｔｉｏｎ Ａｒｅａ」の文字は緑色の薄い軟質プラスチックシートから切り抜いたカッティングシートが用いられている。   The light guide plate 11 is manufactured using, for example, a glass plate, and a pattern 15 is attached to the surface thereof. The pattern 15 is cut out from a colored light-transmitting or non-light-transmitting thin soft plastic sheet into a shape of characters or figures. It is manufactured using a cutting sheet. For example, “Arrow”, “500 m” and “Tsunami figure” are blue, and “Tsunami Evacuation Area”, “Human” and “Tsunami Evacuation Area” are cut from a green thin soft plastic sheet.

また、導光板１１の裏面の図柄１５の背後の位置には光の反射図柄１６が例えばレーザー加工又はブラスト加工によって図柄１５と同一の大きさでかつ同一の形状に形成されている。   Further, a light reflection pattern 16 is formed in the same size and the same shape as the pattern 15 by, for example, laser processing or blasting at a position behind the pattern 15 on the back surface of the light guide plate 11.

導光板１１の側面、例えば上方側面には嵌め込み凹部（光入射部）１１Ａが形成され、該嵌め込み凹部１１ＡにはＬＥＤ（発光素子）１７が適当な間隔をあけて嵌め込まれ、ＬＥＤ１７には駆動回路（図示せず）からの電流が通電されて発光し、導光板１１の内方に向けて光を入射させるようになっている。   A fitting recess (light incident portion) 11A is formed on the side surface of the light guide plate 11, for example, the upper side surface, and an LED (light emitting element) 17 is fitted into the fitting recess 11A with an appropriate interval. A current from (not shown) is energized to emit light, and light is incident toward the inside of the light guide plate 11.

他方、裏板１２には白色のプラスチック板が用いられている。なお、ＬＥＤ１７の電源は商用電源でもよく、蓄電池でもよく、太陽電池であってもよい。   On the other hand, a white plastic plate is used for the back plate 12. The power source of the LED 17 may be a commercial power source, a storage battery, or a solar battery.

昼間には太陽光Ｌ１が導光板１１の表面から背面に向けて入射すると、図３の(a)に示されるように、入射した光Ｌ１は裏板１２の表面で導光板１１の表面に向けて反射されるので、誘導標識１０の正面からは裏板１２の白色が透明な導光板１１を通してそのまま見え、図柄１５は太陽光の反射光によってその輪郭が鮮明にかつ白色の背景に鮮明に見えるので、昼間であっても誘導標識１０を明瞭に視認することができる。   When sunlight L1 is incident from the surface of the light guide plate 11 toward the back surface in the daytime, the incident light L1 is directed toward the surface of the light guide plate 11 on the surface of the back plate 12 as shown in FIG. From the front of the guide sign 10, the white color of the back plate 12 can be seen as it is through the transparent light guide plate 11, and the pattern 15 can be clearly seen by the reflected sunlight and the white background can be clearly seen. Therefore, the guidance sign 10 can be clearly visually recognized even in the daytime.

夜間になると、ＬＥＤ１７が発光し、その光は導光板１１の側面から導光板１１の内方に向けて入射する。すると、図３の(b)に示されるように、導光板１１に入射した光のうち、導光板１１の表面又は裏面で反射された光は導光板１１の裏面又は表面に向かい、導光板１１の裏面又は表面で反射されるという挙動を繰り返すので、裏板１２の白色は誘導標識１０の外側からはほとんど認識できない。   At night, the LED 17 emits light, and the light enters from the side surface of the light guide plate 11 toward the inside of the light guide plate 11. Then, as shown in FIG. 3B, among the light incident on the light guide plate 11, the light reflected on the front surface or the back surface of the light guide plate 11 faces the back surface or the front surface of the light guide plate 11, and the light guide plate 11. Therefore, the white color of the back plate 12 can hardly be recognized from the outside of the guide sign 10.

他方、導光板１１に入射した光のうち、導光板１１の反射図柄１６で反射された光は導光板１１の表面に向かって進み、導光板１１の表面から出射し、導光板１１の表面の図柄１５は出光する光によってその輪郭が明瞭に見えるので、夜間には誘導標識１０の図柄１５は黒い背景に浮き上がって見える。   On the other hand, among the light incident on the light guide plate 11, the light reflected by the reflection pattern 16 of the light guide plate 11 proceeds toward the surface of the light guide plate 11, is emitted from the surface of the light guide plate 11, and is reflected on the surface of the light guide plate 11. Since the outline of the symbol 15 can be clearly seen by the emitted light, the symbol 15 of the guide sign 10 appears to float on a black background at night.

図４は第２の実施形態を示し、これは歩道などに設けられる誘導ブロックに適用した例である。本例では導光板１１’の下側には白色の裏板が設けられ、導光板１１’の上側がポリカーボネート製の保護カバー２０によって覆われ、保護カバー２０の表面には滑り止め用の凸部が形成されている。   FIG. 4 shows a second embodiment, which is an example applied to a guidance block provided on a sidewalk or the like. In this example, a white back plate is provided below the light guide plate 11 ′, the upper side of the light guide plate 11 ′ is covered with a protective cover 20 made of polycarbonate, and a non-slip convex portion is formed on the surface of the protective cover 20. Is formed.

導光板１１’の表面には「路上禁煙」及び「禁止と煙草とからなる禁煙の図形」の図柄１５’がカッティングシートを用いて形成され、導光板１１’の裏面には図柄１５’に対応して光反射図柄が形成されている。   On the surface of the light guide plate 11 ′, “road smoking cessation” and “no smoking figure consisting of prohibition and cigarette” are formed using a cutting sheet, and the back surface of the light guide plate 11 ′ corresponds to the pattern 15 ′. Thus, a light reflection pattern is formed.

また、導光板１１’の両側方にはＬＥＤが配置され、導光板１１’の上方には太陽電池２１が配置され、太陽電池２１を電源とするＬＥＤの通電回路が裏板の下側スペースに内蔵されている。   Further, LEDs are arranged on both sides of the light guide plate 11 ′, a solar cell 21 is arranged above the light guide plate 11 ′, and an energization circuit of the LED that uses the solar cell 21 as a power source is in a lower space of the back plate. Built in.

本例の誘導ブロックにおいても第１の実施形態と同様の作用効果を奏し、昼間には図柄１５’は太陽光の反射光によってその輪郭が鮮明にかつ白色の背景に鮮明に見える一方、夜間になると図柄１５’は黒い背景に浮き上がって見える。   The guide block of this example also has the same effect as that of the first embodiment. In the daytime, the pattern 15 ′ is clearly reflected on the white background by the reflected light of sunlight, but at night The pattern 15 'appears to float on a black background.

図５及び図６は第３の実施形態を示し、図において図１ないし図３と同一符号は同一又は相当部分を示す。本例では導光板１１と裏板１２との間にカッティングシート１８が介在され、カッティングシート１８は着色した透光性の薄い軟質プラスチックシートを用い、反射図柄１６の背後に位置して反射図柄１６と同一の大きさでかつ同一の形状の図柄１９が打ち抜き形成されている。   5 and 6 show a third embodiment, in which the same reference numerals as those in FIGS. 1 to 3 denote the same or corresponding parts. In this example, a cutting sheet 18 is interposed between the light guide plate 11 and the back plate 12, and the cutting sheet 18 uses a colored light-transmitting thin soft plastic sheet, and is positioned behind the reflecting pattern 16 to reflect the reflecting pattern 16. A pattern 19 having the same size and the same shape is punched out.

本例では太陽光Ｌ１が導光板１１の表面から内部に向けて入射されると、図６の(a)に示されるように、着色された透光性のカッティングシート１８を通って裏板１２に達し、裏板１２で導光板１１の表面に向けて反射され、導光板１１の表面側にはカッティングシート１８の色と図柄１９を通して裏板１２の白色が見え、導光板１１の表面の図柄１５の廻りに裏板１２の白色が見え、図柄１５は太陽光の反射光によってその輪郭が白色に鮮明にかつカッティングシート１８の色の背景に鮮明に見えるので、昼間であっても誘導標識１０を明瞭に視認することができる。   In this example, when the sunlight L1 is incident from the surface of the light guide plate 11 toward the inside, the back plate 12 passes through the colored translucent cutting sheet 18 as shown in FIG. Is reflected toward the surface of the light guide plate 11 by the back plate 12, and the white color of the back plate 12 is visible on the surface side of the light guide plate 11 through the color of the cutting sheet 18 and the design 19. Since the white of the back plate 12 can be seen around 15, and the outline of the pattern 15 can be clearly seen in white by the reflected light of sunlight and the background of the color of the cutting sheet 18 can be clearly seen. Can be clearly seen.

夜間になると、ＬＥＤ１７が発光し、その光は導光板１１の側面から導光板１１の内方に向けて入射する。すると、図６の(b)に示されるように、導光板１１に入射した光のうち、導光板１１の表面又は裏面で反射された光は導光板１１の裏面又は表面に向かい、導光板１１の裏面又は表面で反射されるという挙動を繰り返すので、カッティングシート１８の色は誘導標識１０の外側からはほとんど認識できない。   At night, the LED 17 emits light, and the light enters from the side surface of the light guide plate 11 toward the inside of the light guide plate 11. Then, as shown in FIG. 6B, among the light incident on the light guide plate 11, the light reflected on the front surface or the back surface of the light guide plate 11 is directed toward the back surface or the front surface of the light guide plate 11. Therefore, the color of the cutting sheet 18 is hardly recognized from the outside of the guide sign 10.

他方、導光板１１に入射した光のうち、導光板１１の反射図柄１６で反射された光は導光板１１の表面に向かって進み、導光板１１の表面から出射し、導光板１１の表面の図柄１５は出光する光によってその輪郭が明瞭に見えるので、夜間には誘導標識１０の図柄１５は黒い背景に浮き上がって見える。   On the other hand, among the light incident on the light guide plate 11, the light reflected by the reflection pattern 16 of the light guide plate 11 proceeds toward the surface of the light guide plate 11, is emitted from the surface of the light guide plate 11, and is reflected on the surface of the light guide plate 11. Since the outline of the symbol 15 can be clearly seen by the emitted light, the symbol 15 of the guide sign 10 appears to float on a black background at night.

図７及び図８は第４の実施形態を示し、図において図５及び図６と同一符号は同一又は相当部分を示す。本例では導光板１１の表面に図柄１５が設けられていない以外は第３の形態と同様である。   7 and 8 show a fourth embodiment, in which the same reference numerals as in FIGS. 5 and 6 indicate the same or corresponding parts. This example is the same as the third embodiment except that the pattern 15 is not provided on the surface of the light guide plate 11.

太陽光Ｌ１が導光板１１の表面から内部に向けて入射されると、図８の(a)に示されるように、着色された透光性のカッティングシート１８を通って裏板１２に達し、裏板１２で導光板１１の表面に向けて反射され、導光板１１の表面側にはカッティングシート１８の色と図柄１９を通して裏板１２の白色が見え、カッティングシート１８の図柄１９がカッティングシート１８の色彩の中に白く浮かんで見え、昼間であっても誘導標識１０を明瞭に視認することができる。   When the sunlight L1 is incident from the surface of the light guide plate 11 toward the inside, as shown in FIG. 8A, it reaches the back plate 12 through the colored translucent cutting sheet 18, Reflected by the back plate 12 toward the surface of the light guide plate 11, the color of the cutting sheet 18 and the white color of the pattern 19 can be seen on the surface side of the light guide plate 11, and the design 19 of the cutting sheet 18 is seen from the cutting sheet 18. The guide sign 10 can be clearly seen even in the daytime.

夜間になると、ＬＥＤ１７が発光し、その光は導光板１１の側面から導光板１１の内方に向けて入射する。すると、図８の(b)に示されるように、導光板１１に入射した光のうち、導光板１１の表面又は裏面で反射された光は導光板１１の裏面又は表面に向かい、導光板１１の裏面又は表面で反射されるという挙動を繰り返すので、カッティングシート１８の色は誘導標識１０の外側からはほとんど認識できない。   At night, the LED 17 emits light, and the light enters from the side surface of the light guide plate 11 toward the inside of the light guide plate 11. Then, as shown in FIG. 8B, among the light incident on the light guide plate 11, the light reflected on the front surface or the back surface of the light guide plate 11 faces the back surface or the front surface of the light guide plate 11, and the light guide plate 11. Therefore, the color of the cutting sheet 18 is hardly recognized from the outside of the guide sign 10.

他方、導光板１１に入射した光のうち、導光板１１の反射図柄１６で反射された光は導光板１１の表面に向かって進み、導光板１１の表面から出射し、反射図柄１６が出光する光によって明瞭に見えるので、夜間には誘導標識１０の反射図柄１６が黒い背景に浮き上がって見える。   On the other hand, of the light incident on the light guide plate 11, the light reflected by the reflection pattern 16 of the light guide plate 11 proceeds toward the surface of the light guide plate 11, is emitted from the surface of the light guide plate 11, and the reflection pattern 16 exits. Since it looks clear by light, the reflection pattern 16 of the guide sign 10 appears to float on a black background at night.
