A light emitting unit 2 includes a cylindrical ferrite 3 through which an AC driven wiring 1 is inserted, a power receiving coil 7 wound around the ferrite, and a light emitting element 9 provided on a substrate 8 arranged on the outer surface side of the ferrite. And a cylindrical resin mold 12 for enclosing the whole. The resin mold has a recess 15 that can approach the ferrite.

Description

本考案は、受電コイルに発光素子が接続された発光部に交流駆動される配線を貫通させ、発光部の受電コイルに電磁誘導で起電力を発生させて発光素子を発光させる電飾装置に係り、特に前記発光素子の点灯・非点灯を交流駆動される配線側での給電のON/OFFでなく、発光部側での簡単な操作で切り替えられるようにした電飾装置に関するものである。   The present invention relates to an electrical decoration device that causes a light-emitting element connected to a light-emitting element to pass through an AC-driven wiring and generates an electromotive force by electromagnetic induction in the power-receiving element of the light-emitting element to cause the light-emitting element to emit light. In particular, the present invention relates to an electrical decoration device in which lighting / non-lighting of the light emitting element can be switched by a simple operation on the light emitting unit side, not on / off of power feeding on the AC driven wiring side.

電飾装置の発光素子へ電力を供給する手段としては、下記特許文献1に示す接続部のようにコネクター・ソケット・半田付け等の機械的接続構造を介して供給するものが一般的であるが、この機械的接続構造の電気的・機械的信頼性を確保するためには、これを設けられるだけの十分な空間が必要であり、これが発光部を大きくし、電飾装置を全体としても大型化してしまう原因となっていた。   As a means for supplying electric power to the light emitting element of the decoration device, one that supplies power through a mechanical connection structure such as a connector, a socket, and soldering as in the connection part shown in Patent Document 1 below is common. In order to ensure the electrical and mechanical reliability of this mechanical connection structure, it is necessary to have enough space to provide this, which enlarges the light emitting part and makes the decoration device large as a whole. It was a cause to become.

このような課題を解決する一方法として、下記特許文献2に示すように、電磁誘導を用いて非接触にて発光素子に電力を供給する電飾装置が提案されている。この電飾装置は、交流駆動される配線に円筒形の発光部が移動可能に設けられたものであるが、発光部は、円筒を縦2分割にして開閉可能とした筐体の内部に、同様に縦2分割にして開閉可能とした円筒形の磁性体を設け、この磁性体に受電コイルをトロダイル状に巻き、筐体の外面に設けた発光素子に受電コイルを接続した構造である。交流駆動される配線を筐体及び磁性体の中心の通孔に挿通させれば、発光部は配線に沿って移動可能となり、発光部は配線に対して任意の位置に設定可能となる。そして配線を交流駆動すれば受電コイルに電磁誘導によって交流起電力が生じ、発光素子が発光する。   As a method for solving such a problem, as shown in Patent Document 2 below, an electrical decoration device that supplies power to a light emitting element in a non-contact manner using electromagnetic induction has been proposed. In this electrical decoration device, a cylindrical light emitting unit is movably provided on a wiring driven by alternating current, but the light emitting unit is arranged inside a casing that can be opened and closed by dividing the cylinder into two vertically, Similarly, a cylindrical magnetic body that can be opened and closed in two vertically divided portions is provided, and a receiving coil is wound around the magnetic body in a troidal shape, and the receiving coil is connected to a light emitting element provided on the outer surface of the housing. If the AC driven wiring is inserted through the central hole of the housing and the magnetic body, the light emitting unit can be moved along the wiring, and the light emitting unit can be set at an arbitrary position with respect to the wiring. When the wiring is AC driven, an AC electromotive force is generated in the power receiving coil by electromagnetic induction, and the light emitting element emits light.

特開平7−230256号公報Japanese Patent Laid-Open No. 7-230256 特開2003−157702号公報JP 2003-157702 A

上記特許文献2に示す電飾装置では、各発光部の筐体及び磁性体は開閉可能であり、必要に応じて開閉することで、交流駆動される配線に対して着脱する操作を行うことができ、発光させる必要がない場合には配線から取り外すことができる。しかし、このような開閉可能な構造は複雑であり、発光部のサイズが大きくなるという問題があった。   In the electrical decoration device shown in Patent Document 2, the casing and the magnetic body of each light emitting unit can be opened and closed, and an operation of attaching and detaching to / from AC driven wiring can be performed by opening and closing as necessary. If it is not necessary to emit light, it can be removed from the wiring. However, such an openable and closable structure is complicated, and there is a problem that the size of the light emitting part increases.

そこで、本願発明者は、電磁誘導を用いた電飾装置において、単純な筒形の磁性体に受電コイルを巻き、その周囲に設けた発光素子に受電コイルを接続し、全体を透光性の樹脂で筒形にモールドしたコンパクトな構成の発光部を提案した。しかし、この発光部は一旦配線を挿通してしまうと、上記特許文献2に示す電飾装置のようには配線から取り外すことができないので、発光部を非点灯とするためには、給電を行う配線側の駆動回路に設けたスイッチを操作する必要がある。   Therefore, the inventor of the present application, in an electrical decoration device using electromagnetic induction, winds a power receiving coil around a simple cylindrical magnetic body, connects the power receiving coil to a light emitting element provided in the periphery thereof, and the whole is translucent. We proposed a light-emitting part with a compact structure molded into a cylinder with resin. However, once this light-emitting part is inserted through the wiring, it cannot be removed from the wiring as in the case of the illumination device shown in Patent Document 2, so power is supplied to turn off the light-emitting part. It is necessary to operate a switch provided in the driving circuit on the wiring side.

しかし、発光部が複数設けられている場合には、配線側のスイッチで個々の発光部を選択的に点灯・非点灯とすることはできない。発光部を個々にON/OFFするためには、各発光部ごとにスイッチを設ける必要があるが、そのような構造は樹脂モールドでコンパクトに構成した発光部の構造を複雑化し、装置としての信頼性を低下させることとなるので、現実的ではない。   However, when a plurality of light emitting units are provided, individual light emitting units cannot be selectively turned on / off by a switch on the wiring side. In order to turn on / off each light emitting unit individually, it is necessary to provide a switch for each light emitting unit. However, such a structure complicates the structure of the light emitting unit that is compactly formed of a resin mold and is reliable as a device. This is not realistic because it reduces the sex.

本考案は、以上説明したような問題を解決するものであり、筒形の磁性体に受電コイルを巻いて発光素子とともに樹脂モールドした発光部を有する電磁誘導式の電飾装置において、個々の発光部にスイッチ等の複雑な構成を設けることなく、簡単な構成で個々の発光部の点灯を制御できるようにすることを目的とする。   The present invention solves the problems as described above, and in an electromagnetic induction type electric decoration device having a light emitting part in which a receiving coil is wound around a cylindrical magnetic body and resin-molded together with a light emitting element, individual light emission An object of the present invention is to enable lighting of individual light emitting units to be controlled with a simple configuration without providing a complicated configuration such as a switch in the unit.

以下、本考案を実施するために実用新案登録出願人が出願時点で最良と思う本考案の実施の形態を図1〜図11を参照して説明する。
1.第1実施形態(図1〜図5)
図1〜図5は本考案の実施の形態において電磁誘導を利用した電飾装置の一例を示すものである。
図1は同電飾装置の原理を示す説明図、図2は同電飾装置の回路構成を示す全体図、図3は同電飾装置の発光部の横断面図、図4は発光部の回路構成図、図5は同電飾装置の作動タイミング図である。
Hereinafter, an embodiment of the present invention which is considered best by the applicant for utility model registration at the time of filing to implement the present invention will be described with reference to FIGS.
1. 1st Embodiment (FIGS. 1-5)
FIGS. 1-5 shows an example of the electrical decoration apparatus using electromagnetic induction in embodiment of this invention.
FIG. 1 is an explanatory view showing the principle of the electrical decoration device, FIG. 2 is an overall view showing the circuit configuration of the electrical decoration device, FIG. 3 is a cross-sectional view of a light emitting portion of the electrical decoration device, and FIG. FIG. 5 is a circuit configuration diagram, and FIG. 5 is an operation timing diagram of the electrical decoration device.

(1)電飾装置の基本構成(図1)
本例の電飾装置は、交流電源を有する給電部に接続されて駆動される配線1(給電コイル)と、この配線1に貫通されるようにして設けられ、配線1に沿って移動可能で任意の位置に設定できる発光部2からなる。この発光部2の設置個数は任意である。発光部2は、発光素子に接続された受電コイルを有する円筒形であり、交流駆動される配線1と受電コイルを電磁結合が成立する給電状態に置くことにより、電磁誘導で発光部2に非接触で給電を行い、発光素子を発光させることができる。
(1) Basic configuration of the illumination device (Fig. 1)
The electrical decoration device of this example is provided so as to penetrate through the wiring 1 connected to a power supply unit having an AC power supply (power supply coil), and is movable along the wiring 1. The light emitting unit 2 can be set at an arbitrary position. The number of the light emitting units 2 installed is arbitrary. The light emitting unit 2 has a cylindrical shape having a power receiving coil connected to the light emitting element, and by placing the AC driven wiring 1 and the power receiving coil in a power supply state in which electromagnetic coupling is established, the light emitting unit 2 is non-conductive to the light emitting unit 2 by electromagnetic induction. Power can be supplied by contact, and the light emitting element can emit light.

図1に模式的に示すように、配線1が駆動されると、発光部2を貫通している配線1には矢印Aで示すような交流が流れる。すると、発光部2の受電コイル(図示せず)が巻装される円筒形のフェライトにおいては、矢印Bに示すように円周方向について交互に向きが変わる磁界が発生する。この磁界により受電コイルに発生する交流を電力として利用し、発光素子(図示せず)を発光駆動する。   As schematically illustrated in FIG. 1, when the wiring 1 is driven, an alternating current as indicated by an arrow A flows through the wiring 1 penetrating the light emitting unit 2. Then, in the cylindrical ferrite around which the power receiving coil (not shown) of the light emitting unit 2 is wound, a magnetic field whose direction changes alternately in the circumferential direction as shown by an arrow B is generated. The alternating current generated in the receiving coil by this magnetic field is used as electric power to drive a light emitting element (not shown) to emit light.

ここで、上述したような作用で発光部2の発光素子が発光している時に、図示のように永久磁石10を発光部に接近させると、この永久磁石10(磁石10とも呼ぶ)の磁場が受電コイル側に誘起される電力が減少するように作用し、受電コイルに発生する電力が低下する。従って、複数の発光部2を貫通している配線1を交流駆動してすべての発光部2が発光する状態において、特定の発光部2のみに磁石10を設ければ、当該磁石10のみを非点灯とし、その他の磁石10を設けない発光部2のみを点灯とすることができる。すなわち、多数の発光部2の各々にスイッチ等を設けなくとも、磁石10を取り付けるだけの簡単な手段で点灯していたものを非点灯とすることができる。   Here, when the light emitting element of the light emitting unit 2 emits light by the action as described above, when the permanent magnet 10 is brought close to the light emitting unit as illustrated, the magnetic field of the permanent magnet 10 (also referred to as the magnet 10) is changed. The power induced on the power receiving coil side acts so as to decrease, and the power generated in the power receiving coil decreases. Therefore, when the wiring 10 penetrating the plurality of light emitting units 2 is AC-driven and all the light emitting units 2 emit light, if the magnet 10 is provided only for the specific light emitting unit 2, only the magnet 10 is not used. Only the light emitting unit 2 that is not provided with the other magnets 10 can be turned on. That is, even if a switch or the like is not provided in each of the large number of light emitting units 2, what has been lit by simple means simply by attaching the magnet 10 can be turned off.

(2)電飾装置の全体の回路構成(図2)
図2に示すように、所望のパターンで配置された給電コイルである配線1には給電部20が接続されている。給電部20は、電源21と、駆動信号の基準となる信号を発生する発振回路22と、必要に応じて発振回路22からの信号をもとに駆動信号に変換する分周回路23と、配線1の駆動タイミングを制御する制御回路24と、制御回路24からの信号により配線1を分周回路23からの信号で数kHz〜数十kHzで交流駆動する駆動回路25とを有している。さらに、給電部20には、配線1に設けた駆動中の発光部2に磁石を設けて消灯し、これによって配線1に流れる電流が増加して他の発光部2の輝度が変化してしまうことを防止するため、前記駆動回路25を制御して駆動回路25から配線1に流れる電流を一定化する定電流回路26も設けられている。
(2) Overall circuit configuration of the illumination device (FIG. 2)
As shown in FIG. 2, a power feeding unit 20 is connected to the wiring 1 that is a power feeding coil arranged in a desired pattern. The power feeding unit 20 includes a power source 21, an oscillation circuit 22 that generates a signal serving as a reference for the drive signal, a frequency dividing circuit 23 that converts the signal from the oscillation circuit 22 into a drive signal based on a signal as necessary, and wiring 1 has a control circuit 24 that controls the drive timing of 1, and a drive circuit 25 that drives the wiring 1 with a signal from the frequency divider circuit 23 at several kHz to several tens of kHz by a signal from the control circuit 24. Further, the power supply unit 20 is provided with a magnet in the light-emitting unit 2 that is being driven provided in the wiring 1 and is turned off, thereby increasing the current flowing in the wiring 1 and changing the luminance of the other light-emitting units 2. In order to prevent this, a constant current circuit 26 for controlling the drive circuit 25 to make the current flowing from the drive circuit 25 to the wiring 1 constant is also provided.

(3)発光部2の回路構成(図3)
図3に示すように、発光部2のフェライト3(磁性体)は、配線1が挿通できるように中心孔4が両端面に貫通した一体構造の円筒形である。
(3) Circuit configuration of the light emitting unit 2 (FIG. 3)
As shown in FIG. 3, the ferrite 3 (magnetic material) of the light emitting unit 2 has a cylindrical structure with an integral structure in which the center hole 4 penetrates both end faces so that the wiring 1 can be inserted.

前記フェライト3の周壁には、皮膜銅線がトロダイル状に巻かれて受電コイル7が構成されている。これらの受電コイル7は交流駆動される配線1と電磁誘導で結合されると誘導起電力を生じる。   On the peripheral wall of the ferrite 3, a coated copper wire is wound in a troidal shape to constitute a power receiving coil 7. When these power receiving coils 7 are coupled to the AC driven wiring 1 by electromagnetic induction, an induced electromotive force is generated.

フェライト3の外周面側には、フェライト3に巻かれた受電コイル7を囲む実質的に円筒形のプリント基板8が配置されている。このプリント基板8には、その外面側にLED等の発光素子9が取り付けられている。発光素子9と受電コイル7との接続構造は後述する。また、プリント基板8の上には電流制限用の抵抗11が実装されて受電コイル7と発光素子9の間に接続されている。本例では、発光素子9と抵抗11は、プリント基板8上の4箇所に、その円筒形の周方向に沿って略90度間隔で配置されている。   A substantially cylindrical printed circuit board 8 surrounding the power receiving coil 7 wound around the ferrite 3 is disposed on the outer peripheral surface side of the ferrite 3. A light emitting element 9 such as an LED is attached to the printed board 8 on the outer surface side. A connection structure between the light emitting element 9 and the power receiving coil 7 will be described later. A current limiting resistor 11 is mounted on the printed circuit board 8 and connected between the power receiving coil 7 and the light emitting element 9. In this example, the light emitting elements 9 and the resistors 11 are disposed at four positions on the printed board 8 at intervals of approximately 90 degrees along the cylindrical circumferential direction.

図3に示すように、前記フェライト3と前記受電コイル7と前記プリント基板8と前記発光ユニット10を内部に包み込むように、貫通孔13を備えた筒状の樹脂モールド12が形成されている。樹脂モールド12の貫通孔13は、フェライト3の中心孔4の内面にある受電コイル7を必要十分な厚さで被覆するように構成されている。   As shown in FIG. 3, a cylindrical resin mold 12 having a through hole 13 is formed so as to wrap the ferrite 3, the power receiving coil 7, the printed circuit board 8, and the light emitting unit 10 inside. The through hole 13 of the resin mold 12 is configured to cover the power receiving coil 7 on the inner surface of the center hole 4 of the ferrite 3 with a necessary and sufficient thickness.

図3に示すように、樹脂モールド12の外周面側は、発光素子9と抵抗11がある部分では厚く形成され、プリント基板8上に部品のない部分ではプリント基板8の表面を覆う程度の薄さの凹部15として形成されている。凹部15は、その内形状が断面略扇形であり、発光部2の円筒形の全軸長にわたって連続して形成されている。この凹部15は、発光素子9の発光を停止させるべく、磁石10を受電コイル7のフェライト3に極力接近させて取り付けるために設けられた取付け部である。また、このように、磁石10を取り付ける凹部15を発光部2の側周面に設けたので、取り付けた磁石10の影響が発光を妨げる必要のない他の発光部2に及ぶ事態は極力避けられる。   As shown in FIG. 3, the outer peripheral surface side of the resin mold 12 is formed thick in a portion where the light emitting element 9 and the resistor 11 are present, and thin enough to cover the surface of the printed circuit board 8 in a portion where there are no components on the printed circuit board 8. A recess 15 is formed. The concave portion 15 has a substantially sectoral cross section and is formed continuously over the entire axial length of the light emitting portion 2. The concave portion 15 is an attachment portion provided to attach the magnet 10 as close as possible to the ferrite 3 of the power receiving coil 7 in order to stop the light emission of the light emitting element 9. Further, since the concave portion 15 for attaching the magnet 10 is provided on the side peripheral surface of the light emitting portion 2 as described above, a situation where the influence of the attached magnet 10 does not need to interfere with light emission extends to another light emitting portion 2 is avoided as much as possible. .

所望の発光部2の発光素子9を非点灯とすべく、受電コイル7に生じる誘導起電力を減衰させるためには、受電コイル7が巻き込まれたフェライト3に対し、交流駆動される配線1によって発生する磁場とは異なる磁場を与える必要があり、磁石10としては高い磁束密度を有するネオジウム、サマリウムコバルト等からなる永久磁石が最適である。また、その形状は、前記凹部15の内形に合致した形状であることが好ましい。   In order to attenuate the induced electromotive force generated in the power receiving coil 7 so that the light emitting element 9 of the desired light emitting unit 2 is not lit, the ferrite 3 around which the power receiving coil 7 is wound is connected to the ferrite 3 by the AC drive 1. It is necessary to apply a magnetic field different from the generated magnetic field. As the magnet 10, a permanent magnet made of neodymium, samarium cobalt or the like having a high magnetic flux density is optimal. The shape is preferably a shape that matches the inner shape of the recess 15.

(4)発光部2の回路構成(図4)
図4にて発光部2の回路構成を説明する。
発光部2は、フェライト3に巻き込まれた一つの受電コイル7と、受電コイル7の両端に接続されて該受電コイル7に誘起された電力で駆動される発光素子9とを有している。本例の発光素子9は4個のLEDであり、導通方向が同じになるように2個ずつ並列に接続したものを、互いに逆極性となるとともに互いに並列となるように接続し、受電コイル7に対しては電流制限用の抵抗11を介してそれぞれ直列となるように接続する。
(4) Circuit configuration of the light emitting unit 2 (FIG. 4)
The circuit configuration of the light emitting unit 2 will be described with reference to FIG.
The light emitting unit 2 includes one power receiving coil 7 wound around the ferrite 3 and a light emitting element 9 connected to both ends of the power receiving coil 7 and driven by the electric power induced in the power receiving coil 7. The light-emitting element 9 of this example is four LEDs, and two LEDs connected in parallel so that the conduction direction is the same are connected so as to have opposite polarities and to be parallel to each other. Are connected in series with each other via a current limiting resistor 11.

(5)作用効果等(図5)
以上説明した構成における作用について説明する。
給電部20の配線1が発光部2の中心孔4を貫通するように発光部2を配線1に対して取り付ける。発光部2は、配線1に沿って移動させることができるので、一旦定めた発光部2の配置は、後に必要に応じて自由に変更することができる。この状態で配線1を駆動すれば、受電コイル7に誘導電流が誘起されてその発光素子9が発光する。各発光部2がすべて発光している状態において、非点灯としたい発光部2の樹脂モールド12の凹部15に磁石10を取り付ければ、磁石10の磁場によって当該発光部2の受電コイル7に誘起される電力が低下し、その点灯が妨げられる。
(5) Effects, etc. (Fig. 5)
The operation of the configuration described above will be described.
The light emitting unit 2 is attached to the wiring 1 so that the wiring 1 of the power feeding unit 20 passes through the center hole 4 of the light emitting unit 2. Since the light emitting unit 2 can be moved along the wiring 1, the arrangement of the light emitting unit 2 once determined can be freely changed later as needed. When the wiring 1 is driven in this state, an induced current is induced in the power receiving coil 7 and the light emitting element 9 emits light. When the magnet 10 is attached to the concave portion 15 of the resin mold 12 of the light emitting unit 2 to be turned off in a state where all the light emitting units 2 emit light, the light receiving unit 7 of the light emitting unit 2 is induced by the magnetic field of the magnet 10. Power is reduced and its lighting is prevented.

上記の作用を図5の駆動タイミング図を参照してさらに詳細に説明する。
図5(a)に示すように、磁石10がない状態において、制御回路24が点灯を指示する信号を任意のパターンで出力すると、図5(b)に示すように配線1(給電コイル)には同様のパターンで交流電圧が印可される。図5(c)に示すように、配線1に設けられている前記発光部2の受電コイル7には電力が誘起され、受電コイル7に接続された発光素子9が点灯する。
The above operation will be described in more detail with reference to the drive timing chart of FIG.
As shown in FIG. 5A, when the control circuit 24 outputs a signal instructing lighting in an arbitrary pattern in the absence of the magnet 10, the wiring 1 (feeding coil) is connected to the wiring 1 as shown in FIG. 5B. AC voltage is applied in the same pattern. As shown in FIG. 5C, power is induced in the power receiving coil 7 of the light emitting unit 2 provided in the wiring 1, and the light emitting element 9 connected to the power receiving coil 7 is turned on.

図5に示すように、非点灯としたい発光部2に磁石を装着すると、図5(c)に示すように受電コイル7に誘起される電力は小さくなり、発光素子9は消灯する。なお、磁石を取り付けると、受電コイル7のインダクタンスが変化して配線1に流れる電流が増加する方向に向くが、定電圧回路26があるので配線1には常に一定の電流が流れる。   As shown in FIG. 5, when a magnet is attached to the light emitting unit 2 that is desired to be turned off, the power induced in the power receiving coil 7 is reduced as shown in FIG. 5C, and the light emitting element 9 is turned off. When the magnet is attached, the inductance of the power receiving coil 7 changes and the current flowing through the wiring 1 increases, but since the constant voltage circuit 26 is provided, a constant current always flows through the wiring 1.

2. Second Embodiment (FIGS. 6 to 8)
FIGS. 6-8 shows the effect of embodiment of the electrical decoration apparatus of this invention using electromagnetic induction compared with a prior art example.
FIG. 6 is a schematic diagram of an electrical decoration device using electromagnetic induction previously proposed by the inventor of the present application, in which a large number of light emitting parts of different emission colors are provided for wiring. FIG. FIG. 8 is a diagram showing wiring routing states and problems when a specific color light emitting unit is excluded from the light emitting unit of the apparatus, and FIG. 8 is a book in which a large number of light emitting units of different emission colors are provided movably to the wiring It is a figure which shows the routing state of the wiring in the case of excluding the light emission part of a specific color in the example electrical decoration apparatus, and its effect. In each of these drawings, the light emission color of the light emitting unit is distinguished by a hatched pattern, a grid pattern, a solid paint pattern, and the like. In these drawings, the “driving unit 40” is the “power feeding unit” of the first embodiment. 20 ”.

図6に示すように、配線1に対して発光部を移動可能に設けてなる電磁誘導を用いた電飾装置において、多数の発光色の発光部で多彩な発光表示を行わせるために、配線1に対して異なる発光色の発光部2を多数個移動可能に設ける構成を本願発明者は案出した。しかし、この場合、多数の発光部2は配線1に貫通されて設けられているので、各発光色の発光部2は隣接して設けられた順序を簡単には変えることができない。また、各発光部2は配線1の交流駆動により一律に発光駆動されるので、特定の発光部2のみを選択して消灯することはできない。   As shown in FIG. 6, in an illumination device using electromagnetic induction in which a light emitting part is provided so as to be movable with respect to the wiring 1, in order to perform a variety of light emitting displays with a plurality of light emitting parts of light emitting colors, The inventor of the present application has devised a structure in which a large number of light emitting portions 2 having different light emission colors with respect to 1 are movable. However, in this case, since the large number of light emitting units 2 are provided so as to penetrate the wiring 1, the order in which the light emitting units 2 of the respective emission colors are provided adjacent to each other cannot be easily changed. Further, since each light emitting unit 2 is uniformly driven to emit light by AC driving of the wiring 1, it is not possible to select only a specific light emitting unit 2 and turn it off.

ここで、例えばべた塗り(黒色)で表示した「アンバー色」の発光を示す発光部2aを表示させたくない場合には、上述したように、「アンバー色」の発光部2aのみを簡単に配線1から外すことはできないし、また配線1を交流駆動しつつ「アンバー色」の発光部2aのみを消灯する手段もないので、図7に示すように、配線1をこれら「アンバー色」の発光部2aに貫通させたままの状態で引き回し、表示エリア外に持ち出す必要があった。このような作業は、配線1を長く引き回す必要があるため非常に煩雑であり、発光色の変更は不便であった。   Here, for example, when it is not desired to display the light emitting portion 2a showing “amber color” light emission displayed in solid color (black), only the “amber color” light emitting portion 2a is simply wired as described above. 7 and there is no means to turn off only the “amber” light emitting part 2a while AC driving the wiring 1, so that the wiring 1 emits light of these “amber” as shown in FIG. It was necessary to draw out the part 2a while leaving the part 2a out of the display area. Such an operation is very complicated because it is necessary to route the wiring 1 for a long time, and changing the emission color is inconvenient.

ところが、本願発明の実施形態を利用すると、永久磁石10を消灯したい発光部2に取り付けるだけで目的とする発光部2のみを消灯させることができるので、消灯した発光部2はそのまま表示エリア内に置いておくことが可能となる。図8に示すように、べた塗り(黒色)で表示した「アンバー色」の発光部2aには磁石10が設けられて配線1の交流駆動にも係わらず発光しないので、この「アンバー色」の発光部2aは、表示エリアの外にまで引き回す必要はなく、その前後の異なる発光色の発光部2の間における短い配線1の部分のみで発光部2の並びから外せばよい。このようにすれば、異なる発光色の多数の発光部2が一定の間隔で並んで表示される電飾装置において、特定の色を消灯とした場合に当該部分において発光部2の間隔が変わるという不自然さが生じない。もちろん、表示部2の間隔を気にしなければ、配線1はそのままで「アンバー色」の発光部2aのみを磁石10で消灯とするだけでもよい。   However, if the embodiment of the present invention is used, only the target light-emitting part 2 can be turned off simply by attaching the permanent magnet 10 to the light-emitting part 2 to be turned off. It can be left. As shown in FIG. 8, the “amber color” light emitting portion 2 a displayed in solid color (black) is provided with a magnet 10 and does not emit light regardless of the AC driving of the wiring 1. The light emitting unit 2a does not need to be routed outside the display area, and only needs to be removed from the arrangement of the light emitting units 2 only by the portion of the short wiring 1 between the light emitting units 2 having different emission colors before and after the display area. In this way, in an illumination device in which a large number of light emitting units 2 of different emission colors are displayed side by side at a constant interval, when a specific color is turned off, the interval of the light emitting units 2 changes in that portion. There is no unnaturalness. Of course, if the distance between the display portions 2 is not taken care of, only the “amber” light-emitting portion 2 a may be turned off by the magnet 10 without changing the wiring 1.

3.第3実施形態(図9〜図11)

3. 3rd Embodiment (FIGS. 9-11)
FIGS. 9-11 shows the other example of the electrical decoration apparatus using electromagnetic induction in embodiment of this invention. FIG. 9 is a perspective view of an electromagnet used in the electrical decoration device, FIG. 10 is a schematic perspective view showing the overall configuration of the electrical decoration device, and FIG. 11 is an operation timing diagram of the electrical decoration device.

本例の電飾装置は、第1の実施形態における磁石10に替えて電磁石30を利用しており、該電磁石30の駆動は、発光部2を発光させるために配線1を交流駆動する駆動部40(第1実施形態の給電部20に相当)によって行われる。   The electrical decoration device of this example uses an electromagnet 30 instead of the magnet 10 in the first embodiment, and the electromagnet 30 is driven by an AC drive of the wiring 1 to cause the light emitting unit 2 to emit light. 40 (corresponding to the power supply unit 20 of the first embodiment).

図9に示す本例の電磁石30は、所定間隔の隙間をおいて互いに平行に対面する2枚のフランジ31,31を基部32において一体とした横断面略コ字形の磁性体(フェライト)33を備えており、この磁性体33の基部32に駆動コイル34が巻装されている。   The electromagnet 30 of this example shown in FIG. 9 includes a magnetic body (ferrite) 33 having a substantially U-shaped cross section in which two flanges 31, 31 facing each other in parallel with a gap of a predetermined interval are integrated at a base portion 32. The drive coil 34 is wound around the base 32 of the magnetic body 33.

図10に示すように、電磁石30は複数個設けられ、各電磁石30はフランジ31を鉛直方向に平行として隙間を上に向け、互いに接近して平行に並べられている。各電磁石30は、駆動部40に接続されている。駆動部40に接続された配線1には、発光色が異なる複数の発光部2が外挿されているが、各発光部2は、配線1を外挿する順番で電磁石30のフランジ31,31の隙間の間に載置されているが、必要に応じて電磁石30から離すこともできる。   As shown in FIG. 10, a plurality of electromagnets 30 are provided, and the electromagnets 30 are arranged close to each other in parallel, with the flange 31 parallel to the vertical direction and the gap facing upward. Each electromagnet 30 is connected to the drive unit 40. A plurality of light emitting units 2 having different emission colors are extrapolated to the wiring 1 connected to the driving unit 40, but each light emitting unit 2 has flanges 31 and 31 of the electromagnet 30 in the order in which the wiring 1 is extrapolated. However, it can be separated from the electromagnet 30 as needed.

本例によれば、発光部2は、電磁石30上に設置されて電磁石30が駆動された場合には、駆動部40が発光部駆動信号によって配線1を交流駆動している場合であっても消灯する。発光部2が電磁石30の上に置かれている場合は電磁石30の駆動信号によって点滅動作を行い、電磁石30から離された場合には各発光部2は連続点灯する。   According to this example, when the light emitting unit 2 is installed on the electromagnet 30 and the electromagnet 30 is driven, even if the driving unit 40 is AC driving the wiring 1 by the light emitting unit driving signal. Turns off. When the light emitting unit 2 is placed on the electromagnet 30, a blinking operation is performed by a drive signal of the electromagnet 30, and when the light emitting unit 2 is separated from the electromagnet 30, each light emitting unit 2 is continuously lit.

上記の作用を図11の駆動タイミング図を参照してさらに詳細に説明する。
図11(a)に示すように、駆動部40は発光部駆動信号によって配線1を連続的に交流駆動している。駆動部40は発光部2を消灯させるために電磁石30を所望のタイミングで駆動するが、本例では例えば同図(b)に示すようなタイミングで駆動するものとする。このため、電磁石30の上に載置された各発光部2では、同図(c)に示すように、電磁石30を駆動していない時には受電コイル7には所定の誘導起電力が生じ、電磁石30を駆動している時には受電コイル7に生じる誘導起電力は弱まる。その結果、同図(d)に示すように、電磁石30を駆動していない時には発光素子9が発光するが、電磁石30を駆動している時には発光素子9は発光しない。
The above operation will be described in more detail with reference to the drive timing chart of FIG.
As shown in FIG. 11A, the driving unit 40 continuously drives the wiring 1 with an AC by a light emitting unit driving signal. The drive unit 40 drives the electromagnet 30 at a desired timing in order to turn off the light emitting unit 2. In this example, the drive unit 40 is driven at a timing as shown in FIG. Therefore, in each light emitting unit 2 placed on the electromagnet 30, as shown in FIG. 5C, when the electromagnet 30 is not driven, a predetermined induced electromotive force is generated in the power receiving coil 7, and the electromagnet When driving 30, the induced electromotive force generated in the receiving coil 7 is weakened. As a result, as shown in FIG. 4D, the light emitting element 9 emits light when the electromagnet 30 is not driven, but the light emitting element 9 does not emit light when the electromagnet 30 is driven.

以上のように、発光部2を電磁石30の上に載置して配線1を連続して交流駆動している場合は、電磁石30を選択的に駆動することで発光している発光部2を消灯することができるが、図11(e)〜(g)に示すように発光部2を電磁石30から離してしまえば、もちろん電磁石30の駆動に係わらず、連続駆動されている配線1によってすべての発光部は連続点灯する。   As described above, when the light emitting unit 2 is placed on the electromagnet 30 and the wiring 1 is continuously AC driven, the light emitting unit 2 that emits light by selectively driving the electromagnet 30 is used. Although the light can be turned off, as shown in FIGS. 11E to 11G, if the light emitting unit 2 is separated from the electromagnet 30, all of the wiring 1 is continuously driven regardless of the driving of the electromagnet 30. The light-emitting part of is continuously lit.

なお、第3実施形態では、電磁石30の上に発光部2を配置するとともに、配線1の交流駆動を連続とし、選択的に電磁石30を駆動することで選択された発光部2のみが発光を抑制されることとしたが、配線1の発光部駆動信号と電磁石30の駆動信号を適当なパターンとして適宜タイミングの調整を図って組み合わせることによっても、任意の複雑な発光動作を行わせることができる。   In the third embodiment, the light emitting unit 2 is disposed on the electromagnet 30, the AC drive of the wiring 1 is continuous, and only the light emitting unit 2 selected by selectively driving the electromagnet 30 emits light. Although it is suppressed, any complicated light emitting operation can be performed by combining the light emitting unit driving signal of the wiring 1 and the driving signal of the electromagnet 30 with appropriate patterns and adjusting the timing appropriately. .
