以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

本実施形態の照明装置１０は、直線状に並べられた複数個（図１では４個）の発光モジュール２と、隣り合う発光モジュール２同士を電気的に接続する少なくとも１個（図１では３個）のコネクタ３とを備える。各発光モジュール２はそれぞれ適宜形状の構造体である器具本体４に固定され、上記の照明装置１０は器具本体４とともに照明器具１を構成する。なお、図１では、一端の発光モジュール２に対してコネクタ３と別の発光モジュール２とが交互に接続される段数が３段となっているが、この段数は適宜増減可能である。   The lighting device 10 of the present embodiment includes a plurality (four in FIG. 1) of light emitting modules 2 arranged in a straight line and at least one (3 in FIG. 1) that electrically connects the adjacent light emitting modules 2 to each other. ) Connectors 3. Each light emitting module 2 is fixed to a fixture main body 4 which is a structure having an appropriate shape, and the lighting device 10 constitutes the lighting fixture 1 together with the fixture main body 4. In FIG. 1, the number of stages in which the connector 3 and another light emitting module 2 are alternately connected to the light emitting module 2 at one end is three, but the number of stages can be increased or decreased as appropriate.

各発光モジュール２は、それぞれ、細長い長方形状のプリント配線板２１を備える。プリント配線板２１の厚さ方向の一面（以下、「実装面」と呼ぶ。）の幅方向（図１での上下方向）の中央部には、複数個（図では６個）の発光ダイオード２０が、長手方向（図１での左右方向）に直線状に並べて等間隔に実装されている。さらに、プリント配線板２１の実装面の長手方向の両端部には、それぞれコネクタ３に接続される被接続部２２が設けられている。   Each light emitting module 2 includes an elongated rectangular printed wiring board 21. A plurality (six in the figure) of light emitting diodes 20 are provided at the center in the width direction (vertical direction in FIG. 1) of one surface in the thickness direction of the printed wiring board 21 (hereinafter referred to as “mounting surface”). Are arranged in a straight line in the longitudinal direction (left and right direction in FIG. 1) at equal intervals. Further, at both ends of the mounting surface of the printed wiring board 21 in the longitudinal direction, connected portions 22 connected to the connectors 3 are provided.

ここで、プリント配線板２１には、図２に示すように、発光ダイオード２０の直列回路を含み電流の往路とされる第１導電路２３１と、導電パターンのみからなり電流の復路とされる第２導電路２３２とが設けられている。なお、図２では、簡単のために２個の発光モジュール２と１個のコネクタ３のみを図示している。各被接続部２２は、それぞれ、第１導電路２３１の一端に電気的に接続された第１被接触子２２１と、第２導電路２３２の一端に電気的に接続された第２被接触子２２２とを有する。各接触子２２１，２２２はそれぞれ例えば金属のような導電材料からなる。   Here, as shown in FIG. 2, the printed wiring board 21 includes a first conductive path 231 including a series circuit of the light emitting diodes 20 as a current forward path and a current return path including only a conductive pattern. Two conductive paths 232 are provided. In FIG. 2, only two light emitting modules 2 and one connector 3 are shown for simplicity. Each connected portion 22 includes a first contacted element 221 electrically connected to one end of the first conductive path 231 and a second contacted element electrically connected to one end of the second conductive path 232. 222. Each of the contacts 221 and 222 is made of a conductive material such as metal.

また、コネクタ３は、図３に示すように、発光ダイオード３０を有する発光ブロック３１と、それぞれ被接続部２２に接続される２個の接続部３２を有するベースブロック３３とからなる。接続部３２と被接続部２２とは例えば嵌合により互いに着脱自在に結合する構造となっている。ここで、図３では接続部３２側を雄側とし被接続部２２側を雌側としているが、雌雄（凹凸）を逆にしてもよい。各接続部３２は、それぞれ、図２に示すように、被接続部２２に結合したときに第１被接触子２２１に接触導通する第１接触子３２１と、被接続部２２に結合したときに第２被接触子２２２に接触導通する第２接触子３２２とを有する。２個の接続部３２の第２接触子２２２同士は互いに電気的に接続されている。各接続部３２がそれぞれ発光モジュール２に接続された状態では、プリント配線板２１の実装面に直交する方向から見て、コネクタ３の発光ダイオード３０と各発光モジュール２の各発光ダイオード２０とは同一直線上に等間隔に並ぶ。   As shown in FIG. 3, the connector 3 includes a light emitting block 31 having a light emitting diode 30 and a base block 33 having two connecting portions 32 connected to the connected portions 22. The connecting portion 32 and the connected portion 22 are configured to be detachably coupled to each other, for example, by fitting. Here, in FIG. 3, the connecting portion 32 side is the male side and the connected portion 22 side is the female side, but the male and female (unevenness) may be reversed. As shown in FIG. 2, each connection portion 32 is connected to the first contact 321 that is in contact with the first contact 221 when coupled to the connection portion 22, and when connected to the connection portion 22. And a second contact 322 in contact with the second contacted element 222. The second contacts 222 of the two connecting portions 32 are electrically connected to each other. In a state where each connection portion 32 is connected to the light emitting module 2, the light emitting diode 30 of the connector 3 and the light emitting diode 20 of each light emitting module 2 are the same when viewed from the direction orthogonal to the mounting surface of the printed wiring board 21. Line up at equal intervals on a straight line.

さらに、ベースブロック３３は、発光ブロック３１が矢印Ａ１で示すように嵌め込まれる嵌合凹部３３０を有し、嵌合凹部３３０の底面には、それぞれ１個ずつの接続部３２において第１接触子２２１に電気的に接続された２個の端子３３１が保持されている。また、発光ブロック３１は、それぞれ発光ダイオード３０の一方ずつの端子に電気的に接続されて発光ブロック３１がベースブロック３３に結合した状態（つまり嵌合凹部３３０に嵌め込まれた状態）で上記の端子３３１に一対一に接触導通する端子３１１を有する。すなわち、発光ブロック３１がベースブロック３３に結合した状態では、２個の接続部３２の第１接触子３２１同士は発光ダイオード３０を介して互いに電気的に接続される。   Further, the base block 33 has a fitting recess 330 into which the light emitting block 31 is fitted as indicated by an arrow A1, and the first contactor 221 is provided on the bottom surface of the fitting recess 330 at each one connection portion 32. Two terminals 331 that are electrically connected to each other are held. In addition, each of the light emitting blocks 31 is electrically connected to one terminal of each of the light emitting diodes 30 so that the light emitting block 31 is coupled to the base block 33 (that is, the light emitting block 31 is fitted in the fitting recess 330). The terminal 331 has a terminal 311 that is in contact with the one-to-one contact 331. That is, in a state where the light emitting block 31 is coupled to the base block 33, the first contacts 321 of the two connecting portions 32 are electrically connected to each other via the light emitting diode 30.

ここで、一端（図２での左端）に位置する発光モジュール２において他の発光モジュール２に接続されない側（図２では左側）の被接続部２２は、各発光ダイオード２０，３０をそれぞれ点灯させる電力を出力する定電流電源６に電気的に接続される。また、他端（図２での右端）に位置する発光モジュール２において他の発光モジュール２に接続されない側（図２では右側）の被接続部２２の第１被接触子２２１と第２被接触子２２２とは、例えばジャンパ線５を介して互いに電気的に接続される。以上により、各発光ダイオード２０，３０は、定電流電源６の出力端間に直列に接続され、回路には矢印Ａ２で示す向きに電流が流れる。上記のような定電流電源６は周知技術で実現可能であるので、詳細な図示並びに説明は省略する。   Here, in the light emitting module 2 located at one end (left end in FIG. 2), the connected portion 22 on the side not connected to the other light emitting module 2 (left side in FIG. 2) lights each of the light emitting diodes 20 and 30 respectively. It is electrically connected to a constant current power source 6 that outputs electric power. In addition, in the light emitting module 2 located at the other end (right end in FIG. 2), the first contacted element 221 and the second contacted part of the connected portion 22 on the side not connected to the other light emitting module 2 (right side in FIG. 2). The child 222 is electrically connected to each other through, for example, the jumper wire 5. As described above, each of the light emitting diodes 20 and 30 is connected in series between the output terminals of the constant current power source 6, and a current flows through the circuit in a direction indicated by an arrow A2. Since the constant current power source 6 as described above can be realized by a well-known technique, detailed illustration and description thereof will be omitted.

上記構成によれば、コネクタ３が発光ダイオード３０を有さない場合に比べ、互いに隣接する発光モジュール２間が暗くなるような輝度むらが抑えられる。   According to the above configuration, the luminance unevenness such that the light emitting modules 2 adjacent to each other become dark can be suppressed as compared with the case where the connector 3 does not have the light emitting diode 30.

ここで、上記の輝度むらを低く抑えるには、コネクタ３の発光ダイオード３０と隣り合う各発光ダイオード２０との距離が、発光モジュール２において互いに隣り合う発光ダイオード２０間の距離と等しく、且つ、コネクタ３の発光ダイオード３０の光色、光束、配光といった特性が発光モジュール２の発光ダイオード２０の特性と共通であることが望ましい。本実施形態では、コネクタ３が、発光ダイオード３０を有する発光ブロック３１と、接続部３２を有するベースブロック３３とからなるので、接続される発光モジュール２に応じて発光ブロック３１を交換することができる。言い換えると、複数種類の発光モジュール２に対してベースブロック３３が共用されることで、コネクタ３全体を発光モジュール２毎に異なるものとする場合に比べて全体としての製造コストを低減することができる。   Here, in order to suppress the luminance unevenness, the distance between the light emitting diode 30 of the connector 3 and each adjacent light emitting diode 20 is equal to the distance between the adjacent light emitting diodes 20 in the light emitting module 2, and the connector It is desirable that the light emitting diode 30 has the same light color, luminous flux, and light distribution characteristics as the light emitting diode 20 of the light emitting module 2. In the present embodiment, since the connector 3 includes the light emitting block 31 having the light emitting diode 30 and the base block 33 having the connection portion 32, the light emitting block 31 can be exchanged according to the light emitting module 2 to be connected. . In other words, since the base block 33 is shared by a plurality of types of light emitting modules 2, the manufacturing cost as a whole can be reduced as compared with the case where the entire connector 3 is different for each light emitting module 2. .

なお、コネクタ３を、上記のように発光ブロック３１とベースブロック３３とで構成する代わりに、ベースブロック３３の上面に発光ダイオード３０が面実装されたような１個のブロックで構成してもよい。または、コネクタ３を、１個ずつの接続部３２を有して互いに着脱自在に結合する２個のブロックで構成してもよい。また、各接続部３２は、上記のような嵌合により発光モジュール２に着脱自在に接続されるものとする代わりに、半田付けによって接続されるものとしてもよい。   The connector 3 may be constituted by a single block in which the light emitting diode 30 is surface-mounted on the upper surface of the base block 33 instead of the light emitting block 31 and the base block 33 as described above. . Alternatively, the connector 3 may be composed of two blocks each having one connection portion 32 and detachably coupled to each other. Further, each connecting portion 32 may be connected by soldering instead of being detachably connected to the light emitting module 2 by fitting as described above.
