特開２００５−３３１７７６号公報JP-A-2005-331776

しかしながら、図１に示すように、文字本体９１に沿って多数の発光ダイオード９２を配置する看板文字は、発光ダイオード９２を配置するのに極めて手間がかかって製造コストが高くなる。それは、各々の文字によって多数の発光ダイオード９２を異なる配列で配置するからである。文字の長手方向に沿って配置される発光ダイオードは、たとえば、文字本体と同じ形状に加工しているフレキシブル基板に固定して、文字本体の内部に配置される。この構造は、フレキシブル基板を文字本体の形状に加工するので、フレキシブル基板の製作に手間がかかり、また、フレキシブル基板の利用効率が悪いので、部品コストも高くなる欠点がある。   However, as shown in FIG. 1, a signboard character in which a large number of light emitting diodes 92 are arranged along the character main body 91 is extremely time consuming to arrange the light emitting diodes 92 and the manufacturing cost is high. This is because a large number of light emitting diodes 92 are arranged in different arrangements for each character. The light-emitting diodes arranged along the longitudinal direction of the character are, for example, fixed to a flexible substrate processed into the same shape as the character main body and arranged inside the character main body. Since this structure processes the flexible substrate into the shape of the character main body, it takes time to manufacture the flexible substrate, and the utilization efficiency of the flexible substrate is poor, so that there is a disadvantage that the component cost is increased.

フレキシブル基板を小さく分割して数個の発光ダイオードを固定してなる基板ユニットとし、複数の基板ユニットを文字本体に沿って配置することで、複数の発光ダイオードを文字に沿って配列することはできる。この構造は、基板ユニットを小さくすることでより小さい文字にも配置できる。ただ、基板ユニットを小さくすると、ひとつの文字本体に多数の基板ユニットを配置する必要があって、組み立てに手間がかかる欠点がある。反対に基板ユニットを大きくして、大きな文字本体に簡単に配置できるようにすると、小さい文字に基板ユニットを配置できなくなる欠点がある。したがって、この構造では、小さい文字から大きな文字まで、簡単に多数の発光ダイオードを配置できない欠点がある。   It is possible to arrange a plurality of light emitting diodes along a character by arranging a plurality of substrate units along a character body by dividing the flexible substrate into small pieces and fixing a plurality of light emitting diodes. . This structure can be placed on smaller characters by making the substrate unit smaller. However, if the substrate unit is made small, it is necessary to arrange a large number of substrate units in one character body, and there is a disadvantage that it takes time to assemble. On the other hand, if the substrate unit is enlarged so that it can be easily arranged on a large character body, there is a disadvantage that the substrate unit cannot be arranged on a small character. Therefore, this structure has a drawback that a large number of light emitting diodes cannot be arranged easily from a small character to a large character.

本発明は、さらに以上の欠点を解決することを目的に開発されたものである。本発明の重要な目的は、簡単かつ容易に、しかも小さい文字から大きな文字にも多数の発光ダイオードを能率よく配置して組み立てコストを著しく低減できる看板文字を提供することにある。   The present invention has been developed for the purpose of solving the above-mentioned drawbacks. An important object of the present invention is to provide a signboard character that can easily and easily arrange a large number of light-emitting diodes from small characters to large characters and can significantly reduce the assembly cost.

図２に示す看板文字は、複数の発光ダイオード２を文字の長手方向に沿って配列している。この図の看板文字は、文字本体１にプリント基板３を介して発光ダイオード２を配置している。   The signboard character shown in FIG. 2 has a plurality of light emitting diodes 2 arranged in the longitudinal direction of the character. The signboard character in this figure has a light emitting diode 2 arranged on a character body 1 via a printed board 3.

文字本体１は、図３の分解斜視図示すように、断面形状を溝型として内側に溝型凹部１０を設けて、溝型凹部１０の長手方向に、複数の発光ダイオード２を固定しているプリント基板３を配置している。   As shown in the exploded perspective view of FIG. 3, the character main body 1 has a cross-sectional shape of a groove shape and is provided with a groove-shaped recess 10 inside, and a plurality of light-emitting diodes 2 are fixed in the longitudinal direction of the groove-shaped recess 10. A printed circuit board 3 is arranged.

文字本体１は、図４の拡大断面図に示すように、底板１１の両側に対向壁１２を設けて、内側に溝型凹部１０を設けている。底板１１と対向壁１２は、ステンレス等の金属板やプラスチック板で製作される。底板１１は金属板やプラスチック板を文字の形状に裁断して製作され、対向壁１２は金属板やプラスチック板を底板１１の両側に沿う形状に曲げ加工して製作される。一対の対向壁１２は、底板１１の両側縁に垂直に固定されて、底板１１と対向壁１２とで溝型凹部１０のある文字本体１が製作される。   As shown in the enlarged sectional view of FIG. 4, the character body 1 is provided with opposing walls 12 on both sides of the bottom plate 11 and a groove-shaped recess 10 on the inside. The bottom plate 11 and the facing wall 12 are made of a metal plate such as stainless steel or a plastic plate. The bottom plate 11 is manufactured by cutting a metal plate or a plastic plate into a character shape, and the opposing wall 12 is manufactured by bending the metal plate or the plastic plate into a shape along both sides of the bottom plate 11. The pair of opposing walls 12 are fixed perpendicularly to both side edges of the bottom plate 11, and the character body 1 having the groove-shaped recess 10 is manufactured by the bottom plate 11 and the opposing wall 12.

図４の文字本体１は、底板１１の両側に対向壁１２を連結しているが、文字本体は、一対の対向壁のみで構成することもできる。この文字本体は、一対の対向壁を文字の形状に加工して、連結ロッド（図示せず）などを介して互いに平行に連結される。一対の対向壁のみで構成される文字本体は、対向壁の間にプリント基板を介して複数の発光ダイオードを文字に沿って配置する。   Although the character main body 1 of FIG. 4 has connected the opposing wall 12 to the both sides of the baseplate 11, a character main body can also be comprised only with a pair of opposing wall. The character main body is connected in parallel to each other via a connecting rod (not shown) by processing a pair of opposing walls into a character shape. A character main body composed of only a pair of opposing walls has a plurality of light emitting diodes arranged along the characters between the opposing walls via a printed circuit board.

図２ないし図４の看板文字は、溝型凹部１０の開口部１３に向かって光を照射するように発光ダイオード２を文字本体１に配置している。この看板文字は、発光ダイオード２を固定しているプリント基板３を文字本体１の溝型凹部１０に収納して、複数の発光ダイオード２を文字に沿って配置している。この看板文字は、図２と図４に示すように、建物の壁面２０などに固定されて、発光ダイオード２で文字を表示する。図４の看板文字は、文字本体１の底板１１を建物の壁面２０と対向する姿勢とし、図５の看板文字は、溝型凹部１０の開口部１３を建物の壁面２０と対向させる姿勢として文字本体１を建物などに固定している。   In the signboard character of FIGS. 2 to 4, the light emitting diode 2 is arranged on the character body 1 so as to irradiate light toward the opening 13 of the groove-shaped recess 10. In this signboard character, the printed circuit board 3 on which the light emitting diode 2 is fixed is housed in the groove-shaped recess 10 of the character body 1, and a plurality of light emitting diodes 2 are arranged along the character. As shown in FIGS. 2 and 4, the signboard character is fixed to the wall surface 20 of the building and the character is displayed by the light emitting diode 2. The signboard character in FIG. 4 has a posture in which the bottom plate 11 of the character main body 1 faces the wall surface 20 of the building, and the signboard character in FIG. 5 has a character in which the opening 13 of the groove-shaped recess 10 faces the wall surface 20 of the building. The main body 1 is fixed to a building or the like.

図４の看板文字は、発光ダイオード２の光を、壁面２０から前面に照射して明るく文字を表示できる。図５の看板文字は、発光ダイオード２の発光で文字の周囲を明るく照射して、文字の輪郭を美しく表示する。   The signboard character of FIG. 4 can display a bright character by irradiating the light from the light emitting diode 2 from the wall surface 20 to the front surface. The signboard character of FIG. 5 illuminates the periphery of the character brightly by the light emission of the light emitting diode 2, and displays the outline of the character beautifully.

図４と図５の看板文字は、発光ダイオード２を光を文字本体１の開口部１３から外部に照射する。この看板文字は、発光ダイオード２の光を文字本体１の外部に直接に照射して、文字を明るく発光させる。   The signboard characters of FIGS. 4 and 5 irradiate the light emitting diode 2 to the outside through the opening 13 of the character body 1. This signboard character irradiates the light of the light emitting diode 2 directly to the outside of the character main body 1 to lighten the character brightly.

図６の看板文字は、発光ダイオード２の光が溝型凹部１０の底面１４に向かって光を照射する。この看板文字も、プリント基板３を文字本体１の溝型凹部１０に収納して複数の発光ダイオード２を文字の形状に配置している。この看板文字は、発光ダイオード２が文字本体１の底面１４に向けて光を照射するので、文字本体１の底板１１、すなわち溝型凹部１０の底面１４を透光プレート１５としている。   The signboard character of FIG. 6 irradiates light from the light emitting diode 2 toward the bottom surface 14 of the groove-shaped recess 10. This signboard character also has a printed circuit board 3 housed in a groove-shaped recess 10 of the character body 1 and a plurality of light emitting diodes 2 arranged in a character shape. Since the light emitting diode 2 irradiates light toward the bottom surface 14 of the character main body 1, the signboard character uses the bottom plate 11 of the character main body 1, that is, the bottom surface 14 of the groove-shaped recess 10 as the translucent plate 15.

図６の看板文字は、発光ダイオード２の光を、透光プレート１５の底板１１に透過させて外部に照射する。この看板文字は、発光ダイオード２の光を底板１１に透過させて外部に照射する。したがって、この看板文字は、溝型凹部１０の開口部１３を閉塞することができる。溝型凹部１０の開口部１３を閉塞する看板文字は、発光ダイオード２を雨水などから保護して内部に配置できる。ただ、前述の図４と図５に示す看板文字も、図示しないが、文字本体の開口部を、透光性を有するプレートで閉塞して、内部に収納された発光ダイオードの光をこのプレートに透過させて外部に照射しながら、発光ダイオードを雨水などから保護できる。   The signboard character of FIG. 6 transmits the light of the light emitting diode 2 to the bottom plate 11 of the translucent plate 15 and irradiates the outside. This sign character irradiates the light from the light emitting diode 2 to the outside through the bottom plate 11. Therefore, this signboard character can block the opening 13 of the groove-type recess 10. The signboard character that closes the opening 13 of the groove-shaped recess 10 can be disposed inside while protecting the light emitting diode 2 from rainwater or the like. However, although the signboard characters shown in FIGS. 4 and 5 are not shown, the opening of the character body is closed with a light-transmitting plate, and the light of the light-emitting diode housed inside is applied to this plate. Light-emitting diodes can be protected from rainwater and the like while being transmitted and irradiated outside.

発光ダイオード２は、プリント基板３に実装され、このプリント基板３が文字本体１に収納されて、複数の発光ダイオード２が文字に沿って配置される。プリント基板３は、文字に沿って変形でき、かつ発光ダイオード２を固定できる幅の溝底部５の両側に一対の側壁部６を有する横断面形状を溝形とするフレキシブル基板４である。   The light emitting diode 2 is mounted on a printed circuit board 3, the printed circuit board 3 is accommodated in the character body 1, and a plurality of light emitting diodes 2 are arranged along the character. The printed circuit board 3 is a flexible substrate 4 that has a pair of side wall portions 6 on both sides of a groove bottom portion 5 having a width that can be deformed along a character and that can fix the light emitting diode 2 and has a groove shape.

フレキシブル基板４は、図３と図７に示すように、溝底部５に所定の間隔で複数の発光ダイオード２を固定して、発光ダイオード２の接続端子２Ｂをフレキシブル基板４の導電部４Ｂにハンダ付けなどの方法で電気接続している。フレキシブル基板４は、可撓性のある絶縁シート４Ａの表面に導電部４Ｂを設けて、導電部４Ｂを発光ダイオード２の接続端子２Ｂに電気接続している。発光ダイオード２に接続している導電部４Ｂは、発光ダイオード２を点灯する電源回路（図示せず）に接続されて、発光ダイオード２に通電して発光させる。フレキシブル基板４は、溝底部５を文字に沿って変形させて、文字本体１の溝型凹部１０に配置される。溝底部５が文字に沿って変形されると、その両側に連結している側壁部６も文字に沿って変形される。   As shown in FIGS. 3 and 7, the flexible substrate 4 has a plurality of light emitting diodes 2 fixed to the groove bottom portion 5 at predetermined intervals, and the connection terminals 2 </ b> B of the light emitting diodes 2 are soldered to the conductive portions 4 </ b> B of the flexible substrate 4. It is electrically connected by a method such as attaching. The flexible substrate 4 is provided with a conductive portion 4B on the surface of a flexible insulating sheet 4A, and the conductive portion 4B is electrically connected to the connection terminal 2B of the light emitting diode 2. The conductive portion 4B connected to the light emitting diode 2 is connected to a power supply circuit (not shown) that lights the light emitting diode 2, and the light emitting diode 2 is energized to emit light. The flexible substrate 4 is disposed in the groove-type recess 10 of the character body 1 by deforming the groove bottom 5 along the character. When the groove bottom portion 5 is deformed along the character, the side wall portions 6 connected to both sides thereof are also deformed along the character.

図３と図７のフレキシブル基板４は、溝底部５に所定の間隔で複数の穴５Ａを設けて、穴５Ａの間に連結部５Ｂを設けている。連結部５Ｂの表面に発光ダイオード２は固定される。この図で示すフレキシブル基板４の連結部５Ｂは、フレキシブル基板４の長手方向に直交する方向に伸びる所定の幅の帯状である。   In the flexible substrate 4 shown in FIGS. 3 and 7, a plurality of holes 5A are provided at a predetermined interval in the groove bottom 5, and a connecting portion 5B is provided between the holes 5A. The light emitting diode 2 is fixed to the surface of the connecting portion 5B. The connecting portion 5 </ b> B of the flexible substrate 4 shown in this figure is a strip having a predetermined width extending in a direction orthogonal to the longitudinal direction of the flexible substrate 4.

溝底部５の横幅（Ｗ）は、文字に沿って変形でき、かつ、ここに発光ダイオード２を固定できるように、好ましくは２ｍｍ〜３ｍｍとする。ただし、溝底部の横幅（Ｗ）は１ｍｍ〜５ｍｍとすることもできる。溝底部の横幅（Ｗ）を狭くして、小さい曲率半径で湾曲でき、広くして大出力の大きい発光ダイオードを固定できる。溝底部５に穴５Ａを設けて、穴５Ａの間を連結部５Ｂで連結しているフレキシブル基板４は、溝底部５の横幅（Ｗ）を広くしながら小さい曲率半径で湾曲できる。   The lateral width (W) of the groove bottom 5 is preferably 2 mm to 3 mm so that it can be deformed along the characters and the light emitting diode 2 can be fixed thereto. However, the lateral width (W) of the groove bottom may be 1 mm to 5 mm. The width (W) at the bottom of the groove can be narrowed and curved with a small radius of curvature, and the light emitting diode with a large output and a large output can be fixed. The flexible substrate 4 in which the hole 5A is provided in the groove bottom part 5 and the holes 5A are connected by the connecting part 5B can be bent with a small curvature radius while widening the lateral width (W) of the groove bottom part 5.

図７のフレキシブル基板４は、所定の幅の帯状のものを中央に沿ってＵ曲して、溝底部５の両側に側壁部６を設けている。このフレキシブル基板４は、溝底部５をＵ曲部とするので、横幅（Ｗ）を広くしながら小さい曲率半径で湾曲できる。とくに、溝底部５をＵ曲し、かつ、ここに穴５Ａを設けて連結部５Ｂで連結する構造は、溝底部５をより小さい曲率半径で湾曲できる。   The flexible substrate 4 of FIG. 7 is U-shaped along a center with a belt-like member having a predetermined width, and side wall portions 6 are provided on both sides of the groove bottom portion 5. Since the flexible substrate 4 has the groove bottom portion 5 as a U-curved portion, the flexible substrate 4 can be bent with a small curvature radius while widening the width (W). Particularly, the structure in which the groove bottom portion 5 is U-curved and the hole 5A is provided here and connected by the connecting portion 5B can be curved with a smaller radius of curvature.

両側の側壁部６を一定の間隔で設けている複数の連結部５Ｂで連結しているフレキシブル基板４は、連結部５Ｂに発光ダイオード２を固定する。ただし、連結部の間に設けている穴の位置に発光ダイオードを配置して、発光ダイオードの両側にある接続端子やリード線を側壁部にハンダ付けなどの方法で連結して、フレキシブル基板に発光ダイオードを固定することもできる。   The flexible substrate 4 in which the side wall portions 6 on both sides are connected by a plurality of connecting portions 5B provided at regular intervals fixes the light emitting diode 2 to the connecting portions 5B. However, light emitting diodes are arranged at the positions of the holes provided between the connecting parts, and the connection terminals and lead wires on both sides of the light emitting diodes are connected to the side wall part by soldering or the like to emit light to the flexible substrate. The diode can also be fixed.

側壁部６は、発光ダイオード２の接続端子２Ｂやリード線を接続する導電部４Ｂを表面側に設けている。導電部４Ｂに発光ダイオード２の接続端子２Ｂやリード線がハンダ付けされて、発光ダイオード２はフレキシブル基板４に電気接続され、また、固定される。   The side wall portion 6 is provided with a connection portion 2B of the light emitting diode 2 and a conductive portion 4B for connecting a lead wire on the surface side. A connection terminal 2B and a lead wire of the light emitting diode 2 are soldered to the conductive portion 4B, and the light emitting diode 2 is electrically connected to the flexible substrate 4 and fixed.

側壁部６の横幅（Ｄ）は、好ましくは３ｍｍ〜１０ｍｍとする。ただし、本発明の看板文字は、側壁部の横幅（Ｄ）を前述の範囲に特定するものでなく、たとえば、側壁部の横幅（Ｄ）を２ｍｍないし５０ｍｍとすることもできる。とくに、大きな看板文字は、側壁部の横幅（Ｄ）を広くして、フレキシブル基板の強度を強くして、文字本体に収納される。側壁部の横幅（Ｄ）を広くすることで、側壁部を含む面内での曲げ強度を強くして、フレキシブル基板を文字本体の溝型凹部に配置できる。また、側壁部は、横幅（Ｄ）を広くしても、文字に沿って簡単に変形できる。   The lateral width (D) of the side wall 6 is preferably 3 mm to 10 mm. However, the signboard character of the present invention does not specify the lateral width (D) of the side wall portion in the above-described range, and for example, the lateral width (D) of the side wall portion can be set to 2 mm to 50 mm. In particular, large signboard characters are accommodated in the character body by increasing the width (D) of the side wall and increasing the strength of the flexible substrate. By widening the lateral width (D) of the side wall portion, the bending strength in the plane including the side wall portion can be increased, and the flexible substrate can be disposed in the groove-type recess of the character body. Further, the side wall portion can be easily deformed along the characters even if the width (D) is widened.

図の発光ダイオード２はチップタイプで、チップ２Ａの両側に一対の接続端子２Ｂを設けている。チップタイプの発光ダイオード２は、両端に設けている接続端子２Ｂを側壁部６にハンダ付けなどの方法で接続して、しっかりと強固にフレキシブル基板４に固定される。ただし、フレキシブル基板に固定される発光ダイオードは、必ずしもチップタイプとする必要はない。発光ダイオードには、一対のリード線を後端から伸びるように設けている砲弾形のものも使用できる。砲弾形の発光ダイオードは、透明のプラスチックに発光チップを埋設して、後端に一対のリード線を引き出す構造としている。この発光ダイオードは、一対のリード線を、側壁部の導電部にハンダ付けしてフレキシブル基板に接続されて、発光部をフレキシブル基板の溝底部に配置する。   The light emitting diode 2 in the figure is a chip type, and a pair of connection terminals 2B are provided on both sides of the chip 2A. The chip-type light emitting diode 2 is firmly and firmly fixed to the flexible substrate 4 by connecting the connection terminals 2B provided at both ends to the side wall portion 6 by a method such as soldering. However, the light emitting diode fixed to the flexible substrate does not necessarily have to be a chip type. As the light emitting diode, a bullet-shaped one provided with a pair of lead wires extending from the rear end can be used. The bullet-shaped light emitting diode has a structure in which a light emitting chip is embedded in a transparent plastic and a pair of lead wires are drawn out at the rear end. In this light emitting diode, a pair of lead wires is soldered to the conductive portion of the side wall portion and connected to the flexible substrate, and the light emitting portion is disposed at the groove bottom portion of the flexible substrate.

溝底部５に所定の間隔で複数の発光ダイオード２を固定しているフレキシブル基板４は、溝底部５を文字に沿って湾曲して、文字本体１の溝型凹部１０に入れて固定される。横幅（Ｗ）の広い溝底部５の文字本体１は、図８に示すように、複数列のフレキシブル基板４を文字に沿って湾曲して、溝型凹部１０に収納して固定される。   The flexible substrate 4 in which the plurality of light emitting diodes 2 are fixed to the groove bottom portion 5 at a predetermined interval is fixed by inserting the groove bottom portion 5 along the character into the groove-shaped recess 10 of the character body 1. As shown in FIG. 8, the character main body 1 of the groove bottom portion 5 having a wide width (W) is curved along the characters and accommodated in the groove-shaped recess 10 to be fixed.

小さい看板文字は、図２ないし図６に示すように、発光ダイオード２を１列に配置して文字に沿って発光させる。文字本体１の溝型凹部１０に収納されたフレキシブル基板４は、側壁部６を文字本体１の対向壁１２の内面に接着して固定され、あるいはＵ曲されたフレキシブル基板４の復元力、すなわち両側の側壁部６が拡開しようとする復元力で、側壁部６を文字本体１の対向壁１２に押し付けて固定する。さらに、図５と図８に示すように、溝型凹部１０にフレキシブル基板４を配置する状態で、溝型凹部１０にポッティング樹脂７を充填し、このポッティング樹脂７でフレキシブル基板４を文字本体１に固定することもできる。ポッティング樹脂７でフレキシブル基板４を文字本体１に固定する看板文字は、フレキシブル基板４を確実に位置ずれしないように文字本体１に固定できる。   As shown in FIGS. 2 to 6, small signboard characters are arranged in a single row with the light emitting diodes 2 to emit light along the characters. The flexible substrate 4 housed in the groove-shaped recess 10 of the character body 1 is fixed by adhering the side wall 6 to the inner surface of the opposing wall 12 of the character body 1, or the restoring force of the U-curved flexible substrate 4, ie, The side wall 6 is pressed against the opposing wall 12 of the character main body 1 and fixed by the restoring force that the side wall 6 on both sides tries to expand. Further, as shown in FIGS. 5 and 8, the potting resin 7 is filled in the groove-shaped recess 10 in a state in which the flexible substrate 4 is disposed in the groove-shaped recess 10, and the flexible substrate 4 is attached to the character body 1 with the potting resin 7. It can also be fixed to. The signboard character that fixes the flexible substrate 4 to the character body 1 with the potting resin 7 can be fixed to the character body 1 so that the flexible substrate 4 is not misaligned.
