Description

本発明は、照明器具に関する。   The present invention relates to a luminaire.

従来、光源としてＬＥＤ素子を備えた照明器具が知られている（例えば、特許文献１参照）。   DESCRIPTION OF RELATED ART Conventionally, the lighting fixture provided with the LED element as a light source is known (for example, refer patent document 1).

特許文献１には、天井面に設置される照明器具（シーリングライト）が開示されている。特許文献１に開示される照明器具は、器具本体と、器具本体に取り付けられる複数の基板と、基板上に実装された複数の発光素子と、配線器具を介して交流電源を受けて直流出力を生成し出力線を介して特定の基板に直流出力を供給する電源供給接続部と、複数の隣接する基板を電気的に接続する配線接続部材とを備えている。   Patent Document 1 discloses a luminaire (sealing light) installed on a ceiling surface. The lighting fixture disclosed in Patent Document 1 receives an AC power supply via a fixture body, a plurality of substrates attached to the fixture body, a plurality of light emitting elements mounted on the substrate, and a wiring fixture, and outputs DC power. The power supply connection part which supplies a direct current | flow output to a specific board | substrate via a production | generation output line, and the wiring connection member which electrically connects a some adjacent board | substrate are provided.

特開２０１３−５８５０３号公報JP, 2013-58503, A

しかしながら、特許文献１に開示された照明器具においては、電源供給接続部に接続する端子及び基板同士を接続する端子を備えた基板と、基板同士を接続する端子を２つ備えた基板とを用いる必要がある。そのため、２種類の基板を作製することによるコスト増加や管理が複雑になるといった問題がある。また、組み立て作業においては、２種類の基板の配置や基板の接続順が決まっている。そのため、組み立て作業者は、基板を誤って配置したり、基板の接続順を間違ったりすることがないように注意しなければならない。その結果、組み立て時間を短縮することが難しく、作業効率が低下する。   However, the lighting fixture disclosed in Patent Document 1 uses a substrate provided with a terminal connected to the power supply connection portion and a terminal for connecting the substrates, and a substrate provided with two terminals for connecting the substrates. There is a need. Therefore, there is a problem that cost increase and management become complicated by producing two kinds of substrates. Further, in the assembling operation, the arrangement of the two types of substrates and the connection order of the substrates are determined. Therefore, the assembler must be careful not to misplace the substrates or to misalign the connection order of the substrates. As a result, it is difficult to shorten the assembly time and the working efficiency is reduced.

また、通常複数の基板を接続する場合、すなわち複数の発光モジュール（発光要素）を電気的に接続する場合、直列接続又は並列接続の何れかが用いられる。ここで、発光モジュールが断線故障した場合を想定すると、直列接続とした場合は、１つの発光モジュールが断線故障すると全ての発光モジュールに電流が流れなくなる。一方、並列接続とした場合は、１つの発光モジュールが断線故障しても他の発光モジュールには電流が流れて過電流が生じるので、過電流保護回路を設けるなどの対策が必要である。よって、並列接続は直列接続より回路の構成が複雑になり、電源回路部の大型化及びコスト増加を招く。   Further, when connecting a plurality of substrates, that is, when electrically connecting a plurality of light emitting modules (light emitting elements), either series connection or parallel connection is used. Here, assuming that the light emitting modules are broken in a line, if one light emitting module is broken in the case of series connection, no current flows in all the light emitting modules. On the other hand, in the case of parallel connection, even if one light emitting module is broken, a current flows in the other light emitting module and an over current occurs, so it is necessary to take measures such as providing an over current protection circuit. Therefore, the parallel connection makes the circuit configuration more complicated than the serial connection, resulting in an increase in size and cost of the power supply circuit portion.

そこで、本発明は、上記課題に鑑みてなされたものであり、組み立て作業において発光要素の接続順を気にする必要がなく、電源回路部の構成が簡単な照明器具を提供することを目的とする。   Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a lighting fixture having a simple configuration of a power supply circuit portion without having to worry about the connection order of light emitting elements in assembly work. Do.

本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。   The problem to be solved by the present invention is as described above, and next, means for solving the problem will be described.

In order to form a symmetrical convex-concave shape as a whole, the resin material is easily filled uniformly in the mold in the resin molding for manufacturing the protective cover 91, and the moldability is good.

以上説明した本実施形態に係る照明器具１１では、電源部３１が器具本体２１の収容部２３内に収容され、電源部３１（電源ケース３５）に設けられた爪部２０を器具本体２１（収容部２３の天板部２６）に設けられた貫通孔２６ａに嵌合して固定するとともに、電源部３１（電源ケース３５）の１箇所をネジやビス等の固定部材２２を用いて器具本体２１（収容部２３の天板部２６）の第２ネジ固定部２６ｂに固定している。また、接続部７１が器具本体２１の収容部２３内に収容され、接続部７１に設けられた爪部７４を器具本体２１（収容部２３）に設けられた貫通孔２５ｃに嵌合して固定するとともに、接続部７１の１箇所をネジやビス等の固定部材２２を用いて器具本体２１（収容部２３）に固定している。このように電源部３１及び接続部７１をそれぞれ器具本体２１に取り付ける際には、各固定部材２２による固定位置（取付位置）である第１ネジ固定部２５ｄ及び第２ネジ固定部２６ｂは作業者から見て左右の一方側に偏在している。このように器具本体２１に取り付ける電源部３１と接続部７１の各々が、爪部と貫通孔により嵌合して器具本体２１に固定されることで作業時のガタツキを防止し、ネジやビス等による固定部材を用いた固定箇所を最小限（本実施形態では、１箇所）にすることが可能となる。ネジやビス等の部品点数を削減することによって、製造コストの低減や組み立て工数を低減することができる。また、固定部材の固定位置（本実施形態では、第１ネジ固定部２５ｄ及び第２ネジ固定部２６ｂ）を作業者から見て左右の一方側に偏在させることによって、固定部材の固定の作業性が向上する。例えば、右利きの作業者であれば、器具本体２１に向かって右側に固定部材の固定位置が偏在していれば、利き手側に固定部材の固定位置があるので作業がしやすい。   In the lighting apparatus 11 according to the present embodiment described above, the power supply unit 31 is accommodated in the accommodation unit 23 of the appliance main body 21, and the claw unit 20 provided in the power supply unit 31 (power supply case 35) is While fitting and fixing to the through-hole 26a provided in the top plate part 26) of the part 23, one place of the power supply part 31 (power supply case 35) is fixed using the fixing member 22 such as a screw or a screw. It fixes to the 2nd screw fixing part 26b of (the top plate part 26 of the accommodating part 23). Also, the connection portion 71 is accommodated in the accommodation portion 23 of the instrument body 21, and the claw portion 74 provided in the connection portion 71 is fitted and fixed to the through hole 25c provided in the instrument body 21 (housing portion 23). At the same time, one place of the connection portion 71 is fixed to the instrument main body 21 (the housing portion 23) using the fixing member 22 such as a screw or a screw. As described above, when the power supply unit 31 and the connection unit 71 are attached to the tool main body 21, the first screw fixing unit 25 d and the second screw fixing unit 26 b which are fixing positions (attaching positions) by the fixing members 22 are workers. It is unevenly distributed on the left and right sides as seen from the side. Thus, each of the power supply unit 31 attached to the instrument main body 21 and the connection section 71 is fitted with the claws and the through holes and fixed to the instrument main body 21 to prevent rattling at the time of operation. It is possible to minimize the number of fixing points using the fixing member according to (1 in this embodiment). By reducing the number of parts such as screws and screws, it is possible to reduce the manufacturing cost and the number of assembling steps. In addition, the workability of fixing the fixing member is achieved by unevenly distributing the fixing position of the fixing member (in the present embodiment, the first screw fixing portion 25d and the second screw fixing portion 26b) to one of the left and right as viewed from the operator. Improve. For example, if it is a right-handed worker, if the fixing position of the fixing member is unevenly distributed on the right side toward the instrument main body 21, work is easy because the fixing position of the fixing member is on the dominant hand side.

また、照明器具１１では、ＬＥＤ光源モジュール４４の基板４３が電源カバー６１の光源配置部６４と光源カバー部９３とにより挟まれて固定される。つまり、各ＬＥＤ光源モジュール４４は、保護カバー９１を電源カバー６１に取り付けることでネジやビス等の固定部材を用いずに電源カバー６１上に固定される。これにより、ネジやビス等の固定部材を用いずに固定できるため、部品点数を削減でき、ＬＥＤ光源モジュール４４に対して固定部材締結によるストレスが少ない。また、ネジやビス等の固定部材を用いずに固定することによって、組み立て工数を低減することができる。さらに、ＬＥＤ光源モジュール４４の基板４３にネジやビス等の固定部材の締結孔を設けないため、基板の小型化や基板内におけるＬＥＤ素子の配置自由度が向上する。   Further, in the lighting fixture 11, the substrate 43 of the LED light source module 44 is sandwiched and fixed by the light source placement portion 64 of the power source cover 61 and the light source cover portion 93. That is, each LED light source module 44 is fixed on the power supply cover 61 without using a fixing member such as a screw or a screw by attaching the protective cover 91 to the power supply cover 61. Thereby, since it can fix without using fixing members, such as a screw and a screw, a number of parts can be reduced and the stress by fixing member fastening to LED light source module 44 is small. Further, by fixing without using a fixing member such as a screw or a screw, the number of assembling steps can be reduced. Furthermore, since the fastening holes of fixing members such as screws and screws are not provided in the substrate 43 of the LED light source module 44, the miniaturization of the substrate and the freedom of arrangement of the LED elements in the substrate are improved.

また、照明器具１１では、電源カバー６１の光源配置部６４にＬＥＤ光源モジュール４４の基板４３の形状に合わせた係合部６４ａ及び係合凸部６４ｂが形成されており、該係合部６４ａ及び係合凸部６４ｂが光源配置部６４の被係合凸部４３ｃ及び部被係合凹部４３ｄに係合することでＬＥＤ光源モジュール４４が容易に電源カバー６１上の適正位置に配置することができる。   Further, in the lighting device 11, the light source placement portion 64 of the power source cover 61 is formed with an engaging portion 64a and an engaging convex portion 64b that conform to the shape of the substrate 43 of the LED light source module 44. The LED light source module 44 can be easily disposed at an appropriate position on the power supply cover 61 by the engagement convex portion 64b engaging with the engaged convex portion 43c and the portion engaged concave portion 43d of the light source placement portion 64. .

また、照明器具１１では、所定の幅を有する略円弧状の複数のＬＥＤ光源モジュール４４により、略円弧状の光源部４１を形成する。このように、複数のＬＥＤ光源モジュール４４を略円環状に組み合わせる構成とすることで、１つの板状の基板素材から切り取って複数の基板４３を作製する際に、該基板４３を基板素材上に並べて配置することが可能であり、円環状の基板を基板素材から切り取るよりも廃棄する部分が少なく製造歩留まりが良くなるため、製造コストが抑えられる。また、このように構成することで、ハンドリング性も良く、作業効率が向上する。   Moreover, in the lighting fixture 11, the substantially arc-shaped light source unit 41 is formed by the plurality of substantially arc-shaped LED light source modules 44 having a predetermined width. As described above, when the plurality of LED light source modules 44 are combined in a substantially annular shape, when the plurality of substrates 43 are manufactured by cutting them out from one plate-like substrate material, the substrates 43 are placed on the substrate materials. It is possible to arrange side by side, and since the portion to be discarded is smaller than in the case where the annular substrate is cut out from the substrate material, the manufacturing yield is improved, so that the manufacturing cost is suppressed. Moreover, by being configured in this way, the handling property is good and the working efficiency is improved.

また、照明器具１１では、受信部位置目印となる凸状部９２ａとチャンネル切替位置を示す刻印部９２ｃが保護カバー９１表面に設けられている。凸状部９２ａや刻印部９２ｃを保護カバー９１表面に設けることによって、受信部８１の照射面側を覆う受信部用のカバーやチャンネル切替の表示を別途設けなくてもよく、部品点数を削減できる。なお、本実施形態では刻印部９２ｃを凹状に形成したが、これに限らず凸状に形成しても良い。   Further, in the lighting device 11, a convex portion 92a serving as a receiver position mark and a marking portion 92c indicating a channel switching position are provided on the surface of the protective cover 91. By providing the convex portion 92a and the marking portion 92c on the surface of the protective cover 91, it is not necessary to separately provide a cover for the reception unit that covers the irradiation surface side of the reception unit 81 and a channel switching indication, and the number of parts can be reduced. . In the present embodiment, the marking portion 92c is formed in a concave shape, but is not limited to this and may be formed in a convex shape.

また、照明器具１１では、光源カバー部９３の外周縁側の傾斜面に、貫通孔９７を有している。貫通孔９７を設けることによって、虫や埃等を容易に除去できるとともに、空気の対流により保護カバー９１内外間の通気性が良くなり、放熱性が向上する。   Further, in the lighting fixture 11, the inclined surface on the outer peripheral edge side of the light source cover portion 93 has a through hole 97. By providing the through holes 97, insects, dust and the like can be easily removed, and the air convection between the inside and the outside of the protective cover 91 improves the air permeability and improves the heat dissipation.

また、照明器具１１では、内周縁部６３に、受信部８１が有する受光部８２に対応する位置に受光窓６３ｂと、チャンネル切替スイッチ８４の一端を露出するための貫通孔６３ｃが設けられている。照明器具１１の中央部付近に受光窓６３ｂを設けることによって、照明器具１１の照射面側（床側）からの送信されるリモコン信号の受光感度のムラを低減することができる。また、受信部８１等を覆うカバー部材を別途要さず、部品点数が削減できる。   Further, in the lighting fixture 11, a light receiving window 63b and a through hole 63c for exposing one end of the channel switching switch 84 are provided in the inner peripheral edge portion 63 at a position corresponding to the light receiving portion 82 of the receiving portion 81. . By providing the light receiving window 63 b in the vicinity of the central portion of the lighting device 11, it is possible to reduce unevenness in the light receiving sensitivity of the remote control signal transmitted from the irradiation surface side (floor side) of the lighting device 11. In addition, the number of parts can be reduced without requiring a separate cover member for covering the receiving unit 81 and the like.

また、照明器具１１では、電源部３１と接続部７１が収容部２３の照射面側に取り付けられ、光源部４１が電源カバー６１照射面側に配置されて収容部２３に取り付けられる。このように構成することにより、照明器具２１の組立工程において、器具本体２１の収容部２３に電源部３１と接続部７１を取り付ける工程と、電源カバー６１に光源部４１を取り付ける工程とに分業化することができるため、組立工程の効率化が図れる。   Further, in the lighting device 11, the power supply unit 31 and the connection unit 71 are attached to the irradiation surface side of the accommodation unit 23, and the light source unit 41 is disposed on the irradiation surface side of the power supply cover 61 and attached to the accommodation unit 23. By configuring in this manner, in the assembly process of the lighting fixture 21, the division of labor into the process of attaching the power supply unit 31 and the connection unit 71 to the housing 23 of the appliance main body 21 and the process of attaching the light source unit 41 to the power supply cover 61 As a result, the assembly process can be made more efficient.

上記の照明器具１１の形態は一例であり、上記の形態に限定されるものではない。例えば、照明器具１１は丸型としたが、角型やその他の形状としてもよい。また、シーリングライトの他、ペンダントライト等に適用してもよい。   The form of the above-mentioned lighting fixture 11 is an example, and is not limited to the above-mentioned form. For example, although the luminaire 11 is round, it may be square or another shape. Moreover, you may apply to a pendant light etc. other than a ceiling light.

上記の器具本体２１の形状は一例であり、本実施形態の形状に限定されるものではない。例えば、照明器具１１の形状が丸型以外の角型やその他の形状である場合には、それに応じた形状とすることができる。また、器具本体２１の形状は、電源部３１の形状に応じて適宜変形させることも可能である。   The shape of the instrument main body 21 described above is an example, and is not limited to the shape of the present embodiment. For example, when the shape of the lighting fixture 11 is a square other than a round shape or another shape, the shape can be made according to the shape. Further, the shape of the tool main body 21 can be appropriately deformed in accordance with the shape of the power supply unit 31.

次に、照明器具１１の回路構成について詳しく説明する。なお、以下に説明する回路構成は本実施形態の照明器具１１の構造以外でも広く照明器具であれば適用することができ、汎用性がある。   Next, the circuit configuration of the lighting fixture 11 will be described in detail. The circuit configuration described below can be widely applied to any lighting device other than the structure of the lighting device 11 of the present embodiment, and has versatility.

図１２は、電源回路部３２と光源部４１との接続を説明する回路図である。図１２では説明の便宜上、４つのＬＥＤ光源モジュール４４を、それぞれ第１モジュール４４１、第２モジュール４４２、第３モジュール４４３、第４モジュール４４４とする。図１２では、第１〜第３モジュール４４１〜４４３は同じ仕様のモジュールが用いられ、第４モジュール４４４は第１〜第３モジュール４４１〜４４３と同じ仕様のモジュールに保安灯用ＬＥＤ素子４４５が追加された仕様となっている。保安灯用ＬＥＤ素子４４５は、例えばＬＥＤ素子４２の相関色温度よりも低い相関色温度の光を出射可能なＬＥＤ素子である。   FIG. 12 is a circuit diagram for explaining the connection between the power supply circuit unit 32 and the light source unit 41. In FIG. 12, for convenience of explanation, the four LED light source modules 44 are respectively referred to as a first module 441, a second module 442, a third module 443, and a fourth module 444. In FIG. 12, the modules with the same specifications are used for the first to third modules 441 to 443, and the fourth module 444 is a module with the same specifications as the first to third modules 441 to 443. The specifications are The security lamp LED element 445 is an LED element capable of emitting light of a correlated color temperature lower than the correlated color temperature of the LED element 42, for example.

なお、複数色のＬＥＤ素子を搭載して調色制御が可能なＬＥＤ光源モジュールを用いる場合は、複数色のＬＥＤ素子のうち一色のＬＥＤ素子（例えば相関色温度が低いＬＥＤ素子）を低照度に調光することで保安灯と同じ機能を実現できるので、保安灯４４５は不要とすることができる。この場合、第１〜第４モジュールには全て同じ仕様のモジュールを用いることができる。また、第１モジュール４４１、第２モジュール４４２、第３モジュール４４３、および第４モジュール４４４は、発光要素の一例である。   In the case of using an LED light source module capable of controlling color adjustment by mounting LED elements of a plurality of colors, the LED element of one color (for example, an LED element having a low correlated color temperature) among the LED elements of a plurality of colors Since the same function as the security light can be realized by dimming, the security light 445 can be omitted. In this case, modules having the same specifications can be used for all of the first to fourth modules. Also, the first module 441, the second module 442, the third module 443 and the fourth module 444 are examples of light emitting elements.

図１２に示すように、外部商用電源がコネクタ３４を介して電源回路部３２（電源基板３３）に接続されている。また、電源回路部３２には第１〜第４モジュール４４１〜４４４と個別に電気的に接続するためのコネクタ３２１が設けられている。なお、コネクタ３２１は、本実施形態では１つのコネクタとしたが、各モジュール４４１〜４４４を接続するそれぞれ別体のコネクタであってもよい。   As shown in FIG. 12, an external commercial power supply is connected to the power supply circuit unit 32 (power supply substrate 33) via the connector 34. Further, the power supply circuit unit 32 is provided with a connector 321 for electrically connecting to the first to fourth modules 441 to 444 individually. The connector 321 is a single connector in the present embodiment, but may be separate connectors for connecting the modules 441 to 444.

コネクタ３２１内には端子として１１本のピンＰ１〜Ｐ１１が並んでいる。ピンＰ１〜Ｐ８は第１〜第４モジュール４４１〜４４４のＬＥＤ素子４２用の端子であり、ピンＰ２とピンＰ３、ピンＰ４とピンＰ５、ピンＰ６とピンＰ７がそれぞれ短絡され、ピンＰ１とピンＰ８が電源（図示せず）に接続されることで直列回路を構成している。ピンＰ９は沿面距離確保用であり、電源基板３３には電気的に接続されていない。ピンＰ１０、Ｐ１１は保安灯用ＬＥＤ素子４４５用の端子であり、電源に接続されている。   In the connector 321, eleven pins P1 to P11 are arranged as terminals. Pins P1 to P8 are terminals for the LED elements 42 of the first to fourth modules 441 to 444, and pins P2 and P3, pins P4 and P5, and pins P6 and P7 are short-circuited, respectively. A series circuit is configured by connecting P8 to a power supply (not shown). The pin P9 is for securing a creeping distance, and is not electrically connected to the power supply substrate 33. Pins P10 and P11 are terminals for the safety light LED element 445, and are connected to a power supply.

ピンＰ１、Ｐ２には第１モジュール４４１のＬＥＤ素子４２が接続されている。ピンＰ３、Ｐ４には第２モジュール４４２のＬＥＤ素子４２が接続されている。ピンＰ５、Ｐ６には第３モジュール４４３のＬＥＤ素子４２が接続されている。ピンＰ７、Ｐ８には第４モジュール４４４のＬＥＤ素子４２が接続されている。ピンＰ１０、Ｐ１１には第４モジュール４４４の保安灯用ＬＥＤ素子４４５が接続されている。ピンＰ９は沿面距離を確保するためにモジュールは接続されていない。   The LED element 42 of the first module 441 is connected to the pins P1 and P2. The LED element 42 of the second module 442 is connected to the pins P3 and P4. The LED element 42 of the third module 443 is connected to the pins P5 and P6. The LED element 42 of the fourth module 444 is connected to the pins P7 and P8. An LED element 445 for a safety light of the fourth module 444 is connected to the pins P10 and P11. The pin P9 is not connected to the module in order to secure a creeping distance.

このように、第１〜第３モジュール４４１〜４４３及び第４モジュール４４４のＬＥＤ素子４２は、各モジュールがコネクタ３２１に接続されることにより、直列接続される。ＬＥＤ素子４２が直列接続されることにより、１つのモジュールが断線故障すると全てのモジュールに電流が流れなくなるので、並列接続の場合に必要となる過電流保護回路は不要である。よって、各モジュール４４１〜４４４を直列接続することにより、並列接続するよりも回路の構成が簡単になり、電源回路部３２の小型化及びコスト低下に繋がる。また、直列接続した場合は並列接続した場合よりも順方向電圧（ＶＦ）が高くなるため変換効率がよい。   Thus, the LED elements 42 of the first to third modules 441 to 443 and the fourth module 444 are connected in series by connecting the modules to the connector 321. Since the LED elements 42 are connected in series, when one module is broken, no current flows in all the modules, so the overcurrent protection circuit required in the case of parallel connection is unnecessary. Therefore, by connecting the modules 441 to 44 in series, the configuration of the circuit becomes simpler than in parallel connection, which leads to downsizing of the power supply circuit unit 32 and cost reduction. Further, in the case of series connection, the forward voltage (VF) is higher than in the case of parallel connection, so that the conversion efficiency is high.

また、４つのモジュール（第１〜第３モジュール４４１〜４４３、第４モジュール４４４のＬＥＤ素子４２）の接続順は任意である。すなわち、各モジュールとコネクタ３２１の端子（ピンＰ１〜Ｐ８）との組み合わせが変わったとしても、点灯状態は変わらない。したがって、組み立て作業時には、作業者はモジュールの配線とコネクタ３２１の端子との接続の組み合わせを意識する必要がない。その結果、組み立て作業時間を短縮することができ、作業効率がよい。さらに、誤接続の可能性もなくなる。また、各モジュールはそれぞれ電源回路部３２へ接続する構成であるため、少なくとも保安灯を除いて共通のモジュールを使用できるので、部品管理が容易となる。   The connection order of the four modules (the first to third modules 441 to 443 and the LED elements 42 of the fourth module 444) is arbitrary. That is, even if the combination of each module and the terminals (pins P1 to P8) of the connector 321 changes, the lighting state does not change. Therefore, at the time of assembly work, the operator does not have to be aware of the combination of the wiring of the module and the connection of the terminals of the connector 321. As a result, the assembly work time can be shortened and the work efficiency is good. Furthermore, there is no possibility of misconnection. Further, since each module is configured to be connected to the power supply circuit unit 32, a common module can be used except for at least the security light, so that component management becomes easy.

図１２は一例であり、電源回路部３２は、各ＬＥＤ光源モジュール４４と個別に電気的に接続され、各ＬＥＤ光源モジュール４４を直列接続して給電する構成であればよい。「各ＬＥＤ光源モジュール４４と個別に電気的に接続される」とは、例えば図１２に示したように、コネクタ３２１に第１〜第４モジュール４４１〜４４４からの各配線５０（配線５０の端部に設けられたコネクタ）が接続される形態である。これ以外にも、コネクタ３２１を用いずに直接各配線５０を半田付け等によって電源基板３３に接続する形態などであってもよい。   FIG. 12 is an example, and the power supply circuit unit 32 may be configured to be electrically connected to each of the LED light source modules 44 individually and to connect each of the LED light source modules 44 in series to supply power. “Electrically connected to each LED light source module 44 individually” means, for example, as shown in FIG. 12, each wire 50 from the first to fourth modules 441 to 444 at the connector 321 (the end of the wire 50 It is a form to which the connector provided in the part is connected. In addition to this, each wiring 50 may be directly connected to the power supply substrate 33 by soldering or the like without using the connector 321.

「各ＬＥＤ光源モジュール４４を直列接続する」とは、例えば図１２に示したように、コネクタ３２１の端子同士が直列接続される形態である。これ以外にも、電源回路部３２内で直列接続されていればよく、コネクタ３２１部分以外で直列に接続されるようにしてもよい。例えば、電源基板３３上のコネクタ３２１から離れた位置で直列接続されるように電源基板３３上の配線を配置してもよい。   “The LED light source modules 44 are connected in series” means, for example, as shown in FIG. 12, the terminals of the connector 321 are connected in series. Other than this, they may be connected in series in the power supply circuit unit 32, and may be connected in series at portions other than the connector 321. For example, the wires on the power supply substrate 33 may be arranged to be connected in series at a position away from the connector 321 on the power supply substrate 33.

なお、図１２では４つのモジュール４４１〜４４４を用いたが、モジュールの数に限定はなく、複数の発光モジュールを用いる形態であればよい。   In addition, although four modules 441-444 were used in FIG. 12, there is no limitation in the number of modules, and a form using a plurality of light emitting modules may be used.

上記の実施形態ではＬＥＤ光源モジュール４４を直列接続する形態を例に説明したが、発光要素を直列接続する形態であればよい。発光要素は光源になり得るものであれば特に限定はなく、発光素子であってもよいし、発光素子を含む発光モジュールであってもよい。   In the above embodiment, the LED light source modules 44 are connected in series as an example, but the light emitting elements may be connected in series. The light emitting element is not particularly limited as long as it can be a light source, and may be a light emitting element or a light emitting module including the light emitting element.
