Description

本発明は、発光ダイオードをプリント基板に固定している照明に関する。   The present invention relates to illumination in which a light emitting diode is fixed to a printed circuit board.

発光ダイオードの照明は、フィラメントのある電球等を使用する照明に比較して、極めて長寿命であるからメンテナンスを簡単にできる特徴がある。ただ、発光ダイオードは1個の輝度が小さいために、多数の発光ダイオードを設けて、全体の輝度を高くする必要がある。多数の発光ダイオードを備える照明は、発光ダイオードをプリント基板に固定して配線を簡素化できる。さらに、多数のプリント基板を連結して、種々の形状や発光輝度の照明を実現できる。このことから、発光ダイオードの照明は、多数のプリント基板を連結する必要がある。   The illumination of the light emitting diode has an extremely long life compared to the illumination using a light bulb with a filament, etc., and thus has a feature that can be easily maintained. However, since one light emitting diode has a small luminance, it is necessary to provide a large number of light emitting diodes to increase the overall luminance. In the illumination including a large number of light emitting diodes, the wiring can be simplified by fixing the light emitting diodes to the printed circuit board. Furthermore, by connecting a large number of printed circuit boards, illumination with various shapes and light emission luminances can be realized. For this reason, it is necessary to connect a large number of printed circuit boards to illuminate the light emitting diode.

発光ダイオードを固定しているプリント基板は、物理的に連結し、また電気的にも接続する必要がある。従来は、プリント基板をネジ等を使用して物理的に連結し、コネクタとリード線を介して電気的に接続している。この構造は、電気的な接続にコネクタとリード線を使用するので、多数のプリント基板を連結するためには、多数のコネクタと長いリード線を必要とする。また、コネクタとリード線を使用するので、連結のための部品コストが高くなる欠点もある。さらに、リード線の端部にコネクタを接続するので、製造に著しく手間がかかる欠点もある。さらに、コネクタは、金属の弾性で接点を電気的に接続するので、長年使用されると接触不良を起こしやすい欠点がある。とくに、屋外の悪い環境で使用されると、接触不良を起こしやすくなる。   The printed circuit board on which the light emitting diode is fixed needs to be physically connected and electrically connected. Conventionally, a printed circuit board is physically coupled using screws or the like, and electrically connected to the connector via a lead wire. Since this structure uses connectors and lead wires for electrical connection, a large number of connectors and long lead wires are required to connect a large number of printed circuit boards. In addition, since the connector and the lead wire are used, there is a drawback that the cost of the parts for connection is increased. Further, since the connector is connected to the end of the lead wire, there is a drawback that it takes much time to manufacture. Further, since the connector electrically connects the contacts with the elasticity of metal, there is a drawback that contact failure is likely to occur when used for many years. In particular, when used in a bad outdoor environment, poor contact is likely to occur.

プリント基板を簡単に連結する構造は、物理的に連結すると電気的にも接続される構造で解消できる。このことを実現する連結構造は開発されている(特許文献1及び2参照)。
特開2002−117707号公報 特開2002−141555号公報
The structure for easily connecting the printed circuit boards can be eliminated by a structure that is electrically connected when physically connected. A connecting structure for realizing this has been developed (see Patent Documents 1 and 2).
JP 2002-117707 A JP 2002-141555 A

特許文献1の公報に記載されるプリント基板の連結構造は、図1の断面図に示すように、発光ダイオード21のリード21Aを2枚のプリント基板22に貫通し、これをプリント基板22に半田付して連結する。この構造は、発光ダイオード21のリード21Aで、2枚のプリント基板22を物理的に連結しながら、電気的にも接続できる。ただ、この接続構造は、細いリード21Aを介して2枚のプリント基板22を物理的に連結するので、しっかりと強靭な構造で連結できない欠点がある。このため、大きなプリント基板をしっかりと連結できない欠点がある。   As shown in the cross-sectional view of FIG. 1, the printed circuit board connection structure described in Patent Document 1 penetrates the leads 21 </ b> A of the light emitting diode 21 through the two printed circuit boards 22 and solders them to the printed circuit board 22. Attach and attach. This structure can be electrically connected while physically connecting the two printed boards 22 with the lead 21A of the light emitting diode 21. However, since this connection structure physically connects the two printed circuit boards 22 through the thin leads 21A, there is a drawback that the connection structure cannot be connected with a firm and strong structure. For this reason, there exists a fault which cannot connect a large printed circuit board firmly.

特許文献2の公報に記載される照明は、互いにプリント基板を連結するものではない。ただ、この公報は、図2と図3に示すように、プリント基板32を内蔵する照明30を器具に物理的に連結しながら電気的に接続する連結構造を記載している。この公報に記載される照明30は、細長管33内に設置されるプリント基板32と、このプリント基板32の上面側に長手方向に沿って所定間隔をおいて配設される多数のLED31とを設け、細長管33の両端に一対のブッシング34を取付けている。ブッシング34は、プリント基板32を細長管33内に固定し、口金具35を保持している。口金具35は、ブッシング34の取付筒部の外周に圧入される金属製胴体35Aと、電源回路部に電気的に接続する1本の電極ピン35Bと、金属製胴体35Aの開口端縁に固定され、電極ピン35Bを支持する絶縁物からなる絶縁円板35Cとを有している。   The illumination described in the publication of Patent Document 2 does not connect printed circuit boards to each other. However, as shown in FIGS. 2 and 3, this publication describes a connection structure in which an illumination 30 containing a printed circuit board 32 is electrically connected to a device while being physically connected. The illumination 30 described in this publication includes a printed circuit board 32 installed in an elongated tube 33 and a large number of LEDs 31 arranged on the upper surface side of the printed circuit board 32 at predetermined intervals along the longitudinal direction. A pair of bushings 34 are attached to both ends of the elongated tube 33. The bushing 34 fixes the printed circuit board 32 in the elongated tube 33 and holds the fitting 35. The metal fitting 35 is fixed to the metal body 35A press-fitted into the outer periphery of the mounting cylinder part of the bushing 34, one electrode pin 35B electrically connected to the power supply circuit part, and the opening edge of the metal body 35A. And an insulating disc 35C made of an insulator that supports the electrode pin 35B.

この照明30は、口金具35を受具(図示せず)に挿入して、物理的に受具に連結され、また、電気的にも接続される。この構造は、連結部の構造が極めて複雑な形状となるばかりでなく、大きくなるので、多数のプリント基板をコンパクトな構造で連結できない。また、連結方向が特定されるので、プリント基板を種々な方向には連結できない欠点もある。また、長期間にわたって接触不良が起こらないようにできない欠点もある。   The illumination 30 is physically connected to the receptacle by inserting the fitting 35 into a receptacle (not shown), and is also electrically connected. In this structure, not only the structure of the connecting portion has an extremely complicated shape but also a large size, and thus a large number of printed circuit boards cannot be connected in a compact structure. In addition, since the connecting direction is specified, there is a drawback that the printed circuit board cannot be connected in various directions. In addition, there is a drawback that contact failure does not occur over a long period of time.

本発明は、こ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、極めて簡単な構造で、簡単かつ容易に、しかも接触不良を極減する状態で複数のプリント基板を物理的に連結しながら電気的に接続できる照明を提供することにある。   The present invention has been developed for the purpose of solving this drawback. An important object of the present invention is to provide an illumination that can be electrically connected while physically connecting a plurality of printed circuit boards with a very simple structure, in a simple and easy manner, and in a state that minimizes contact failure. is there.

The plurality of printed circuit boards 2 are physically connected to each other and electrically connected so that the light emitting diodes 1 fixed to the connected printed circuit boards 2 emit light. The printed circuit board 2 opens a through hole 4 through which the stopper 3 is inserted, and a connection conductive portion 5 is provided around the through hole 4. The connection conductive parts 5 are provided on both surfaces of the printed circuit board 2, and one or both of the connection conductive parts 5 are insulated from the inner surface of the through hole 4. Further, the printed circuit board 2 to which the light emitting diode 1 is fixed has a pair of connection conductive portions 5 provided on both surfaces thereof connected to a pair of connection terminals of the light emitting diode 1 via lead conductive portions 6 provided on the surface. By connecting, power is supplied to the light emitting diode 1 from the pair of connection conductive portions 5. In this illumination, a plurality of printed circuit boards 2 are laminated so that the through holes 4 coincide with each other, the connection conductive portions 5 that are in contact with each other are electrically connected, and the through holes 4 are electrically conductive stoppers. 3, the printed circuit board 2 is connected to the laminated state with the stopper 3, and both ends of the stopper 3 are brought into contact with the connection conductive portions 5 provided on the surface of the printed circuit board 2. The connection conductive portion 5 on the surface side of the substrate 2 is electrically connected.

本発明の照明は、プリント基板2が、発光ダイオード1を固定している発光用のプリント基板2Aと、発光ダイオード1を固定しない連結用のプリント基板2Bとを備え、発光ダイオード1を固定しているプリント基板2を、発光ダイオード1を固定していない連結用のプリント基板2Bで連結することができる。   In the illumination according to the present invention, the printed circuit board 2 includes a light emitting printed circuit board 2A to which the light emitting diode 1 is fixed, and a connecting printed circuit board 2B to which the light emitting diode 1 is not fixed. The printed circuit board 2 can be connected by a connection printed circuit board 2B to which the light emitting diode 1 is not fixed.

本発明の照明は、止具3が、止ネジ3Aと、この止ネジ3Aにねじ込まれるナット3Bを備えることができる。   In the illumination of the present invention, the stopper 3 can include a set screw 3A and a nut 3B screwed into the set screw 3A.

本発明の照明は、複数のプリント基板2を文字や図形等の表示形状に配置している看板とすることも、複数のプリント基板2を連結している装飾用の照明とすることもできる。   The illumination of the present invention may be a signboard in which a plurality of printed circuit boards 2 are arranged in a display shape such as characters and figures, or may be a decorative illumination that connects a plurality of printed circuit boards 2.

本発明の照明は、複数のプリント基板2を物理的に連結して、接続導電部5を介して複数のプリント基板2を並列に接続することができる。   The illumination according to the present invention can physically connect the plurality of printed circuit boards 2 and connect the plurality of printed circuit boards 2 in parallel via the connection conductive portion 5.

本発明の照明は、プリント基板2の両面に設けている接続導電部5を貫通孔4の周囲から絶縁して配置することができる。   In the illumination according to the present invention, the connection conductive portions 5 provided on both surfaces of the printed circuit board 2 can be insulated from the periphery of the through hole 4.

さらに、本発明の照明は、2枚のプリント基板2を積層して物理的に連結すると共に、一対の接続導電部5を電気的に接続することができる。   Furthermore, the illumination of the present invention can stack and physically connect two printed boards 2 and can electrically connect a pair of connection conductive portions 5.

本発明の照明は、極めて簡単な構造としながら、簡単かつ容易に、しかも接触不良を極減する状態で複数のプリント基板を物理的に連結しながら電気的に接続できる特長がある。それは、本発明の照明が、プリント基板に貫通孔を開口して、貫通孔の周囲であってプリント基板の両面に接続導電部を設けており、両面に設けている接続導電部は、少なくとも一方の接続導電部を貫通孔の内面から絶縁しており、さらに、両面に設けている一対の接続導電部をリード導電部を介して、発光ダイオードに接続して、一対の接続導電部から発光ダイオードに電力を供給するようにし、さらにまた、複数のプリント基板は貫通孔が一致するように積層されて、対向して接触される接続導電部を電気接続し、さらに、貫通孔に導電性のある止具を挿通して、止具で積層状態のプリント基板を物理的に連結し、また、止具の両端をプリント基板の表面に設けている接続導電部に接触させて、止具でプリント基板の表面側の接続導電部を電気接続するからである。   The illumination according to the present invention has an advantage that it can be electrically connected while physically connecting a plurality of printed circuit boards in a state where contact failure is minimized while having an extremely simple structure. That is, the illumination of the present invention has a through hole in the printed circuit board, and the connection conductive part is provided on both sides of the printed circuit board around the through hole. At least one of the connection conductive parts provided on both surfaces is provided. Are electrically insulated from the inner surface of the through hole, and a pair of connection conductive portions provided on both sides are connected to the light emitting diode via the lead conductive portion, and the light emitting diode is connected to the light emitting diode from the pair of connection conductive portions. In addition, the plurality of printed circuit boards are stacked so that the through holes coincide with each other, electrically connect the connecting conductive portions that are opposed to each other, and the through holes are conductive. Insert the stopper, physically connect the stacked printed circuit boards with the stopper, and bring the both ends of the stopper into contact with the connection conductive part provided on the surface of the printed circuit board, and the printed circuit board with the stopper. Connecting conductive part on the surface side of This is because the electrical connection.

以上の構造でプリント基板を連結する照明は、貫通孔を同じ位置として積層して、貫通孔に止具を入れ、止具の両端の鍔部でプリント基板を挟着して、プリント基板を物理的に連結して、電気的に接続できる。このため、プリント基板を電気的に接続するためにコネクタやリード線を使用する必要がなく、使用部品を少なくしながら、簡単に電気的に接続できる。   The lighting that connects the printed circuit boards with the above structure is made by stacking the through holes at the same position, inserting fasteners into the through holes, and sandwiching the printed circuit boards at the flanges at both ends of the fasteners to physically place the printed circuit boards. Can be connected and electrically connected. For this reason, it is not necessary to use a connector or a lead wire to electrically connect the printed circuit board, and it can be easily electrically connected while reducing the number of parts used.

さらに、本発明の照明は、止具で積層しているプリント基板を挟着して、物理的に連結しながら、電気的に接続するので、コネクタやリード線で接続する構造に比較して接触不良を極減できる特長がある。それは、コネクタが、金属の弾性変形を利用して接点を押圧して電気接続するのに対し、止具の鍔部でプリント基板を挟着して電気接続する構造は、たとえば止ネジやナットの止具、あるいはリベット等を止具でもって、確実に強い力で鍔部を接続導電部に押圧して電気接続できるからである。また、止具のナットは、強く止ネジにねじこんで押圧力を強くでき、またリベットは、強く押圧できるように叩いて変形することができるので、押圧力を調整して、より確実に電気接続して接触不良を極減できる。   Furthermore, since the illumination of the present invention is electrically connected while sandwiching the printed circuit boards laminated with the fasteners and physically connecting them, it is in comparison with the structure connected with the connector or the lead wire. There is a feature that can reduce defects. This is because the connector uses the elastic deformation of the metal to press the contacts to make electrical connections, while the structure that connects the printed circuit board with the hooks of the fasteners to make electrical connections is, for example, a set screw or nut. This is because the hook or the rivet or the like can be securely connected to the connecting conductive portion by pressing the collar portion with a strong force. In addition, the nut of the fastener can be strongly screwed into the set screw to increase the pressing force, and the rivet can be deformed by hitting it so that it can be pressed strongly. Connection failure can be minimized.

さらにまた、接続導電部を強い力で押圧して電気接続できるので、接続部の接触抵抗を著しく小さくして、理想的な状態で接続できる特長も実現される。また、押圧状態で電気接続される接続導電部は、経時的に電気抵抗が増加したり、あるいは接触不良となるのも確実に阻止して、安定して長期間にわたって低い電気抵抗で接続できる特長もある。   In addition, since the connection conductive portion can be pressed and electrically connected with a strong force, the contact resistance of the connection portion can be remarkably reduced and an advantage of being able to connect in an ideal state is realized. In addition, the connection conductive part that is electrically connected in the pressed state can reliably connect with a low electric resistance over a long period of time, reliably preventing electrical resistance from increasing over time or causing poor contact. There is also.

また、プリント基板は、貫通孔の周囲に接続導電部を設けているので、プリント基板を、止具を中心に自由に回転させる姿勢で連結でき、連結方向が特定されない特長もある。このことは、たとえば、図4に示すように、多数のプリント基板を連結し、あるいは同じプリント基板を異なる状態で連結して、違う配列の照明とすることができるなど、同じプリント基板を使用して、種々の形状の照明を実現できる特長がある。   In addition, since the printed circuit board is provided with the connection conductive portion around the through hole, the printed circuit board can be connected in a posture in which the printed circuit board is freely rotated around the stopper, and the connection direction is not specified. This is because, for example, as shown in FIG. 4, a large number of printed circuit boards can be connected, or the same printed circuit boards can be connected in different states to provide different arrangements of illumination. In addition, there is a feature that can realize illumination of various shapes.

また、本発明の請求項2の照明は、発光ダイオードを設けている発光用のプリント基板を、発光ダイオードのない連結用のプリント基板を介して連結しているので、発光用のプリント基板に同じ回路構成のものを使用して、種々の組み合われの照明にできる特長がある。それは、互いに連結されるプリント基板の上下の接続導電部が極性が同じになるからである。   In the illumination according to claim 2 of the present invention, since the light-emitting printed circuit board provided with the light-emitting diode is connected via a connection printed circuit board without the light-emitting diode, it is the same as the light-emitting printed circuit board. There is a feature that can be used in various combinations of illumination using a circuit configuration. This is because the upper and lower connecting conductive parts of the printed circuit boards connected to each other have the same polarity.

以下、本発明の実施例を図面に基づいて説明する。ただし、以下に示す実施例は、本発明の技術思想を具体化するための照明を例示するものであって、本発明は照明を以下のものに特定しない。   Embodiments of the present invention will be described below with reference to the drawings. However, the example shown below illustrates the illumination for embodying the technical idea of the present invention, and the present invention does not specify the illumination as follows.

さらに、この明細書は、特許請求の範囲を理解しやすいように、実施例に示される部材に対応する番号を、「特許請求の範囲」および「課題を解決するための手段の欄」に示される部材に付記している。ただ、特許請求の範囲に示される部材を、実施例の部材に特定するものでは決してない。   Further, in this specification, in order to facilitate understanding of the scope of claims, numbers corresponding to the members shown in the examples are indicated in the “claims” and “means for solving problems” sections. It is added to the members. However, the members shown in the claims are not limited to the members in the embodiments.

本発明の照明は、複数のプリント基板を、文字や図形等の表示形状に配置して看板として使用される。この照明は、複数のプリント基板を、文字や図形等を表示する形状に連結して、これをケースに収納して看板として使用する。また、本発明の照明は、複数のプリント基板を種々の平面的な形状に連結し、あるいは立体的な形状に連結して、装飾用の照明として使用される。   The illumination of the present invention is used as a signboard by arranging a plurality of printed circuit boards in a display shape such as letters and figures. In this illumination, a plurality of printed circuit boards are connected to a shape for displaying characters, figures, etc., and this is housed in a case and used as a signboard. In addition, the illumination of the present invention is used as a decoration illumination by connecting a plurality of printed circuit boards in various planar shapes or in a three-dimensional shape.

図4は装飾用の照明を示す。この照明は、細長い複数のプリント基板2の両端を互いに連結して、全体の形状を球形としている。この照明は、発光ダイオードを装着している細長いプリント基板2で三角形を形成するように、交点において5本または6本のプリント基板2を放射状に連結している。発光ダイオードを有する発光用のプリント基板2Aは、図5に示すように6本を放射状に連結し、あるいは図示しないが、5本を放射状に連結している。発光用のプリント基板2Aは、発光ダイオードを装着しない連結用のプリント基板2Bを介して、連結している。図5と図6に示すプリント基板2は、連結用のプリント基板2Bを介して発光用のプリント基板2Aを連結している。ただ、本発明の照明は、連結用のプリント基板を介することなく、発光用のプリント基板を直接に連結することもできる。   FIG. 4 shows decorative lighting. In this illumination, both ends of a plurality of elongated printed circuit boards 2 are connected to each other so that the overall shape is spherical. In this illumination, five or six printed circuit boards 2 are radially connected at intersections so as to form a triangle with the elongated printed circuit boards 2 on which the light emitting diodes are mounted. As shown in FIG. 5, six printed circuit boards 2A for light emission having light emitting diodes are connected radially, or five are connected radially, although not shown. The light emitting printed circuit board 2A is connected via a connecting printed circuit board 2B to which no light emitting diode is attached. The printed circuit board 2 shown in FIGS. 5 and 6 is connected to a light emitting printed circuit board 2A via a connection printed circuit board 2B. However, the illumination of the present invention can directly connect the light emitting printed circuit board without using the connection printed circuit board.

複数のプリント基板2は、止具3を介して互いに物理的に連結され、さらに、止具3を介して電気的にも接続される。プリント基板2を電気的に接続するのは、接続部からプリント基板2に電力を供給して、プリント基板2に固定している発光ダイオード1に通電して発光させるためである。   The plurality of printed circuit boards 2 are physically connected to each other via a stopper 3 and are also electrically connected to each other via the stopper 3. The reason why the printed circuit board 2 is electrically connected is that power is supplied to the printed circuit board 2 from the connecting portion and the light emitting diode 1 fixed to the printed circuit board 2 is energized to emit light.

プリント基板2は、止具3を介して連結できるように、止具3を挿通する貫通孔4を開口している。貫通孔4は、止具3を挿通できるように、止具3よりもわずかに大きい円形孔である。さらに、この止具3を介して物理的に連結される状態で、プリント基板2を電気的に接続するために、貫通孔4の周囲に接続導電部5を設けている。接続導電部5は、プリント基板2に電力を供給するために、プリント基板2の両面に設けている。プリント基板2の両面に設けている一対の接続導電部5は、正負の直流電力をプリント基板2に供給し、あるいは極性のない交流電力をプリント基板2に供給する。   The printed board 2 has a through hole 4 through which the stopper 3 is inserted so that the printed board 2 can be connected via the stopper 3. The through hole 4 is a circular hole slightly larger than the stopper 3 so that the stopper 3 can be inserted. Furthermore, a connection conductive portion 5 is provided around the through hole 4 in order to electrically connect the printed circuit board 2 in a state of being physically coupled via the stopper 3. The connection conductive portion 5 is provided on both surfaces of the printed circuit board 2 in order to supply power to the printed circuit board 2. The pair of connection conductive portions 5 provided on both surfaces of the printed circuit board 2 supplies positive and negative DC power to the printed circuit board 2 or supplies AC power having no polarity to the printed circuit board 2.

プリント基板2の両面に設けている一対の接続導電部5は、正負の直流電力を供給し、あるいは極性のない交流電力を供給する。したがって、一対の接続導電部5が互いに接触すると短絡する。貫通孔4には導電性の止具3を挿通するので、この止具3が一対の接続導電部5に接触すると短絡する。したがって、プリント基板2の両面に設けている一対の接続導電部5は、一方又は両方を貫通孔4の内面から絶縁して配置している。図6のプリント基板2は、プリント基板2の両面に設けている接続導電部5を貫通孔4の内面から絶縁している。とくに、図に示すプリント基板2は、両面に設けている接続導電部5を、貫通孔4の周囲から絶縁して配置している。このプリント基板2は、貫通孔4の内面で両方の接続導電部5が止具3に接触せず、止具3による短絡を効果的に阻止できる。   The pair of connection conductive portions 5 provided on both surfaces of the printed circuit board 2 supplies positive and negative DC power, or supplies AC power having no polarity. Therefore, a short circuit occurs when the pair of connection conductive portions 5 come into contact with each other. Since the conductive stopper 3 is inserted into the through hole 4, a short circuit occurs when the stopper 3 comes into contact with the pair of connection conductive portions 5.

One or a plurality of light emitting diodes 1 are fixed to the light emitting printed circuit board 2A. FIG. 7 shows a circuit diagram of a light-emitting printed circuit board 2A on which a plurality of light-emitting diodes 1 are mounted. In the printed circuit board 2A for light emission shown in this circuit diagram, ten light emitting diodes 1 are fixed. The light emitting diode 1 is connected to the connection conductive portion 5 by connecting in parallel five pieces connected in series via the lead conductive portion 6. The light emitting diodes 1 are connected in series and in parallel via the lead conductive part 6 and connected to the connection conductive part 5. As shown in this circuit diagram, the light emitting printed circuit board 2A in which the plurality of light emitting diodes 1 are connected in series can increase the supply voltage of the connection conductive portion 5. As shown in FIG. 8, the printed circuit board 2A for light emission is provided with a constant voltage circuit 7 for stabilizing the supply voltage to a constant voltage, and the supply voltage is made constant by the constant voltage circuit 7 and supplied to the light emitting diode 1. You can also. In addition, as shown in FIG. 9, the light emitting diode 1 can be connected to the connection conductive portion 5 through the current limiting resistor 8.

さらに、図10の回路図に示す発光用のプリント基板2Aは、接続導電部5に発光ダイオード1を点灯する電源回路9を接続している。電源回路9は、整流用のダイオード10と平滑用コンデンサ11を備える。平滑用コンデンサ11は、整流用のダイオード10を介して入力側の接続部5Aに接続される。平滑用コンデンサ11は、一対の接続導電部5の入力電圧が0Vになる状態で、平滑用コンデンサ11の電圧が低下するのを阻止する。平滑用コンデンサ11は、接続導電部5の入力電圧が一時的に低下するときに、出力電圧が低下するのを保持する。この電源回路9は、図示しないが、平滑用コンデンサの出力に、出力電圧を一定に制御する定電圧回路を設けて、発光ダイオードを一定の明るさに点灯することができる。   Further, the printed circuit board 2 </ b> A for light emission shown in the circuit diagram of FIG. 10 has a power supply circuit 9 for lighting the light emitting diode 1 connected to the connection conductive portion 5. The power supply circuit 9 includes a rectifying diode 10 and a smoothing capacitor 11. The smoothing capacitor 11 is connected to the input side connection portion 5 </ b> A via the rectifying diode 10. The smoothing capacitor 11 prevents the voltage of the smoothing capacitor 11 from decreasing when the input voltage of the pair of connection conductive portions 5 becomes 0V. The smoothing capacitor 11 holds that the output voltage decreases when the input voltage of the connection conductive portion 5 temporarily decreases. Although not shown, the power supply circuit 9 can be provided with a constant voltage circuit for controlling the output voltage at the output of the smoothing capacitor to light the light emitting diode with a constant brightness.

さらに、図10の回路図に示す発光用のプリント基板2Aは、接続導電部5に制御回路12を接続している。制御回路12は、一対の接続導電部5に入力される制御信号を検出して、発光用のプリント基板2Aに実装している発光ダイオード1の点滅をコントロールする。制御回路12が発光ダイオード1の点灯を制御するために、発光ダイオード1はスイッチング素子13を介して電源回路9に接続している。発光ダイオード1は、直列に接続しているスイッチング素子13がオンに切り換えられる状態で点灯して、オフに切り換えられる状態で消灯される。   Furthermore, the printed circuit board 2 </ b> A for light emission shown in the circuit diagram of FIG. 10 has the control circuit 12 connected to the connection conductive portion 5. The control circuit 12 detects a control signal input to the pair of connection conductive portions 5 and controls blinking of the light emitting diode 1 mounted on the light emitting printed circuit board 2A. In order for the control circuit 12 to control the lighting of the light emitting diode 1, the light emitting diode 1 is connected to the power supply circuit 9 via the switching element 13. The light emitting diode 1 is turned on when the switching element 13 connected in series is turned on, and turned off when the switching element 13 is turned off.

この回路図に示すプリント基板2は、発光ダイオード1の点滅をコントロールする制御信号を接続導電部5から入力して、発光ダイオード1の点滅をコントロールできる。制御信号は、一対の接続導電部5に供給する電圧を、”High”と”Low”に切り換えるパルス信号である。接続導電部5に、”High”と”Low”に切り換えられるパルス信号の制御信号が入力されると、この信号を制御回路12が検出して、発光ダイオード1の点滅をコントロールする。発光ダイオード1の電源回路9は、接続導電部5に入力される電圧が”High”と”Low”に切り換えられると、”High”のときに平滑用コンデンサ11をチャージして、出力電圧を一定に保持する。   The printed circuit board 2 shown in this circuit diagram can control the blinking of the light emitting diode 1 by inputting a control signal for controlling the blinking of the light emitting diode 1 from the connection conductive portion 5. The control signal is a pulse signal for switching the voltage supplied to the pair of connection conductive portions 5 between “High” and “Low”. When a control signal of a pulse signal that can be switched between “High” and “Low” is input to the connection conductive portion 5, the control circuit 12 detects this signal and controls blinking of the light emitting diode 1. When the voltage input to the connection conductive portion 5 is switched between “High” and “Low”, the power supply circuit 9 of the light emitting diode 1 charges the smoothing capacitor 11 when “High” and the output voltage is constant. Hold on.

この回路構成のプリント基板2は、信号端子を設けることなく、発光用のプリント基板2Aに実装する発光ダイオード1の点滅をコントロールできる。   The printed circuit board 2 having this circuit configuration can control blinking of the light-emitting diode 1 mounted on the printed circuit board 2A for light emission without providing a signal terminal.

プリント基板2の連結構造を図5と図6に示す。これ等の図に示す連結構造は、連結用のプリント基板2Bに発光用のプリント基板2Aを連結する構造を示している。連結されるプリント基板2は、貫通孔4を一致するように積層して、対向して接触される接続導電部5を電気接続する。さらに、貫通孔4に導電性のある止具3を挿通して、止具3で積層しているプリント基板2を物理的に連結する。さらに、止具3の両端をプリント基板2の表面に設けている接続導電部5に接触させて、止具3でプリント基板2の非対向面である表面側の接続導電部5を電気接続する。   The connection structure of the printed circuit board 2 is shown in FIGS. The connection structure shown in these drawings shows a structure in which the light emission printed circuit board 2A is connected to the connection printed circuit board 2B. The printed circuit boards 2 to be coupled are stacked so that the through holes 4 coincide with each other, and the connection conductive portions 5 that are in contact with each other are electrically connected. Further, the conductive stopper 3 is inserted into the through hole 4 to physically connect the printed circuit boards 2 stacked with the stopper 3. Furthermore, both ends of the fastener 3 are brought into contact with the connection conductive portion 5 provided on the surface of the printed circuit board 2, and the connection conductive portion 5 on the surface side which is the non-facing surface of the printed circuit board 2 is electrically connected by the fastener 3. .

図5と図6の連結構造は、発光用のプリント基板2Aを連結用のプリント基板2Bを介して連結している。この連結構造は、連結用のプリント基板2Bで連結される発光用のプリント基板2Aの上面と下面の極性を同じにできる。たとえば、連結される2枚のプリント基板2は、上面の接続導電部5が正極で、下面が負極となり、あるいは反対に上面の接続導電部が負極で、下面が正極となる。したがって、連結用のプリント基板2Bを介して連結されるプリント基板2は、全く同じ回路構成のものを使用できる。   In the connection structure shown in FIGS. 5 and 6, the printed circuit board 2A for light emission is connected through the printed circuit board 2B for connection. In this connection structure, the polarities of the upper surface and the lower surface of the light emitting printed circuit board 2A connected by the connection printed circuit board 2B can be made the same. For example, in the two printed circuit boards 2 to be connected, the connection conductive portion 5 on the upper surface is a positive electrode and the lower surface is a negative electrode, or conversely, the connection conductive portion on the upper surface is a negative electrode and the lower surface is a positive electrode. Accordingly, the printed circuit board 2 connected via the connecting printed circuit board 2B can have the same circuit configuration.

ただし、本発明の照明は、2枚のプリント基板を積層して同じ連結構造で連結することができる。この連結構造で上下に積層される2枚のプリント基板は、上下の接続導電部の極性が互いに反転する。上面のプリント基板が上面の接続導電部を正極、下面を負極とするとき、下面のプリント基板は、上面の接続導電部を負極、下面を正極とするようになる。したがって、上下に積層して連結するプリント基板は、接続導電部の極性を反対にするものを使用する。   However, the illumination of the present invention can be formed by stacking two printed circuit boards and connecting them with the same connection structure. In the two printed boards that are stacked one above the other in this connection structure, the polarities of the upper and lower connecting conductive portions are reversed from each other. When the upper printed circuit board has a connection conductive portion on the upper surface as a positive electrode and a lower surface as a negative electrode, the lower printed circuit board has a connection conductive portion on the upper surface as a negative electrode and the lower surface as a positive electrode. Therefore, the printed circuit boards that are stacked and connected in the upper and lower directions are those in which the polarity of the connection conductive portion is reversed.

さらに、プリント基板は、図11に示すように、偶数枚を積層して連結することができる。偶数枚のプリント基板2は、貫通孔4を同じ位置に配置して積層され、貫通孔4に止ネジ3A等の止具3が挿通される。止具3である止ネジ3Aにナット3Bをねじこんで、積層しているプリント基板2を物理的に連結し、かつ、接続導電部5を電気的に接続できる。偶数枚のプリント基板2が積層されると、最も外側の接続導電部5は同じ極性となる。積層面で互いに接触する接続導電部5は、同じ極性となって電気的に接続される。したがって、偶数枚のプリント基板2を積層して、外側の接続導電部5を止具3で連結して、全てのプリント基板2を電気的に接続できる。   Furthermore, as shown in FIG. 11, the printed circuit boards can be connected by stacking even numbers. The even number of printed circuit boards 2 are stacked with the through holes 4 arranged at the same position, and a stopper 3 such as a set screw 3 </ b> A is inserted through the through hole 4. The nut 3B is screwed into the set screw 3A which is the stopper 3, so that the laminated printed circuit boards 2 can be physically coupled, and the connection conductive portion 5 can be electrically connected. When an even number of printed circuit boards 2 are stacked, the outermost connection conductive portion 5 has the same polarity. The connection conductive parts 5 that are in contact with each other on the laminated surface have the same polarity and are electrically connected. Therefore, it is possible to electrically connect all the printed circuit boards 2 by laminating an even number of printed circuit boards 2 and connecting the outer connecting conductive parts 5 with the stoppers 3.

4枚以上のプリント基板を積層して、止具で連結する連結構造も、上下に積層されるプリント基板は、接続導電部の極性が上下で反転する。したがって、上下に積層するプリント基板には、接続導電部の極性を反転したものを使用する。   In the connection structure in which four or more printed boards are stacked and connected by a fastener, the polarity of the connection conductive portion is reversed up and down in the printed board stacked up and down. Therefore, the printed circuit board laminated on the upper and lower sides is one in which the polarity of the connection conductive portion is reversed.

図12は、接続導電部5から交流を供給して発光ダイオード1を点灯する発光用のプリント基板2Aの回路図を示す。この発光用のプリント基板2Aは、接続導電部5から入力される交流を整流用のダイオード10で整流し、整流された脈流を平滑用コンデンサ11で平滑な直流として発光ダイオード1を点灯する。平滑用コンデンサ11の出力側には、図示しないが、出力電圧を一定にする定電圧回路を設けることができる。定電圧回路の出力側に発光ダイオード1を接続して点灯する。この回路構成のプリント基板2は、接続導電部5に交流を入力するので、一対の接続導電部5に極性がない。したがって、同じ回路構成の発光用のプリント基板2Aを積層して連結して、発光ダイオード1を点灯できる。   FIG. 12 shows a circuit diagram of a printed circuit board 2A for light emission in which alternating current is supplied from the connection conductive portion 5 and the light emitting diode 1 is turned on. The printed circuit board 2A for light emission rectifies the alternating current input from the connection conductive portion 5 with the rectifying diode 10 and turns on the light emitting diode 1 with the rectified pulsating flow as a smooth direct current with the smoothing capacitor 11. Although not shown, a constant voltage circuit that makes the output voltage constant can be provided on the output side of the smoothing capacitor 11. Lights up by connecting the light emitting diode 1 to the output side of the constant voltage circuit. Since the printed circuit board 2 having this circuit configuration inputs alternating current to the connection conductive portion 5, the pair of connection conductive portions 5 have no polarity. Therefore, the light emitting diode 1 can be turned on by stacking and connecting the light emitting printed circuit boards 2A having the same circuit configuration.
