図２に照明装置１０の放熱器１１および光源装置１２の正面図を示す。 FIG. 2 shows a front view of the radiator 11 and the light source device 12 of the lighting device 10.

放熱器１１は、熱伝導性および放熱性に優れた例えばアルミニウムなどの金属製で、前面側には光源装置１２を配設する光源取付面２０が設けられている。光源取付面２０は、平面状で、例えば、正四角形、あるいは縦方向や横方向が長い長方形などの四角形状の外形に形成されている。光源取付面２０の外形は、四角形に限らず、五角形以上の多角形や、円形などでもよい。放熱器１１の背面側には、放熱フィンなどの放熱構造を備えていてもよい。 The heat radiator 11 is made of a metal such as aluminum, which has excellent thermal conductivity and heat dissipation, and is provided with a light source mounting surface 20 on the front side on which the light source device 12 is disposed. The light source mounting surface 20 is planar and has a square outer shape, such as a regular square or a rectangle that is long in the vertical and horizontal directions. The outer shape of the light source mounting surface 20 is not limited to a quadrangle, but may be a polygon of pentagon or more, a circle, or the like. The back side of the heat radiator 11 may be provided with a heat dissipation structure such as a heat dissipation fin.

光源装置１２は、複数の光源モジュール２２ａ，２２ｂ，２２ｃ（第１の光源モジュール２２ａ、第２の光源モジュール２２ｂ、第３の光源モジュール２２ｃともいう）を備えている。光源モジュール２２ａ，２２ｂ，２２ｃは、光源装置１２の中心点Ｏを中心とする周方向の所定の角度毎に分割された形状であって、例えば１２０度毎に３つに分割された形状に形成されている。これら３つの光源モジュール２２ａ，２２ｂ，２２ｃが中心点Ｏを中心とする周方向に隣接するように集合して配置されることで、１つの光源モジュール集合体である光源装置１２が形成される。 The light source device 12 includes a plurality of light source modules 22a, 22b, and 22c (also referred to as a first light source module 22a, a second light source module 22b, and a third light source module 22c). The light source modules 22a, 22b, and 22c have a shape that is divided into predetermined angles in the circumferential direction centering on the center point O of the light source device 12, and are formed into a shape that is divided into three parts every 120 degrees, for example. has been done. By arranging these three light source modules 22a, 22b, and 22c so as to be adjacent to each other in the circumferential direction around the center point O, the light source device 12, which is one light source module assembly, is formed.

各光源モジュール２２ａ，２２ｂ，２２ｃは、基板２３と、この基板２３の一面側である前面側にそれぞれ実装された複数の発光素子２４および複数のコネクタ２５と、を備えている。 Each of the light source modules 22a, 22b, and 22c includes a substrate 23, and a plurality of light emitting elements 24 and a plurality of connectors 25 mounted on the front side, which is one side of the substrate 23, respectively.

図２および図３に示すように、基板２３は、５つの頂点Ｐ１～Ｐ５と５つの辺を有する五角形に形成されている。五角形は、中心点Ｏに対応した１つの頂点Ｐ１を通る仮想線に対して左右に線対称となる五角形に形成されている。例えば、五角形は、頂点Ｐ１から、頂点Ｐ１に対向する辺に向かって伸ばした垂線に対して左右対象となっている。 As shown in FIGS. 2 and 3, the substrate 23 is formed into a pentagon having five vertices P1 to P5 and five sides. The pentagon is formed to be horizontally symmetrical with respect to an imaginary line passing through one vertex P1 corresponding to the center point O. For example, a pentagon is symmetrical with respect to a perpendicular line extending from the vertex P1 toward the side opposite the vertex P1.

基板２３は、図２のように中心点Ｏに３つの基板２３の頂点Ｐ１が位置するように３つの基板２３を集合して配設した際、隣接する他の基板２３と対向する対向辺部２６と、他の基板２３と対向しない非対向辺部２７と、を備えている。対向辺部２６は、第１の対向辺部２６ａと第２対向辺部２６ｂの２つを備え、また、非対向辺部２７は、第１の非対向辺部２７ａと第２の非対向辺部２７ｂと第３の非対向辺部２７ｃの３つを備えている。基板２３は、２つの対向辺部２６ａ，２６ｂと３つの非対向辺部２７ａ，２７ｂ，２７ｃとを有する五角形に形成され、３つの基板２３が集合されることで、正六角形の基板集合体が形成される。本実施形態では、３つの基板２３を集合配設し、それぞれの基板２３が２つの対向辺部２６を備える構成となるが、この形態に限定されるものではない。例えば、４つの基板２３を集合配設し、それぞれの基板２３が２つの対向辺部２６を備える構成であってもよいし、５つの基板２３を集合配設し、３つの対向辺部２６を有する基板２３と、４つの対向辺部２６を有する基板２３と、を備える構成であってもよい。なお、Ｎ枚の基板２３を集合配設する場合は、最大Ｎ－１の数量の対向辺部２６を備える構成となる。また、この場合、Ｎは３以上であることが好ましい。言い換えれば、対向辺部２６の最小数量は２つであることが好ましい。 When the three substrates 23 are collectively arranged so that the apex P1 of the three substrates 23 is located at the center point O as shown in FIG. 26, and a non-opposing side portion 27 that does not face the other substrate 23. The opposing side portion 26 includes a first opposing side portion 26a and a second opposing side portion 26b, and the non-opposing side portion 27 includes a first non-opposing side portion 27a and a second non-opposing side portion 26b. It has three parts: a portion 27b and a third non-opposing side portion 27c. The substrate 23 is formed into a pentagonal shape having two opposing sides 26a, 26b and three non-opposing sides 27a, 27b, 27c, and when the three substrates 23 are assembled, a regular hexagonal substrate assembly is formed. It is formed. In this embodiment, three substrates 23 are arranged in a group, and each substrate 23 has two opposing sides 26, but the present invention is not limited to this configuration. For example, four substrates 23 may be arranged together and each substrate 23 has two opposing sides 26, or five substrates 23 may be arranged together and three opposing sides 26 are provided. The substrate 23 may include a substrate 23 having a substrate 23 and a substrate 23 having four opposing sides 26. Note that when N substrates 23 are arranged in a group, the configuration is such that a maximum number of opposing sides 26 is N-1. Moreover, in this case, it is preferable that N is 3 or more. In other words, it is preferable that the minimum number of opposing sides 26 is two.

１つの基板２３において、対向辺部２６ａ，２６ｂは、頂点Ｐ１を介して１２０度の角度をもって形成されている。３つの非対向辺部２７ａ，２７ｂ，２７ｃのうち、第１の非対向辺部２７ａは、第１の対向辺部２６ａとの間の頂点Ｐ２を介して９０度の角度をもって形成され、第２の非対向辺部２７ｂは、第２の対向辺部２６ｂとの間の頂点Ｐ３を介して９０度の角度をもって形成され、第３の非対向辺部２７ｃは、各非対向辺部２７ａ，２７ｂとの間の各頂点Ｐ４，Ｐ５を介してそれぞれ１２０度の角度を介して形成されている。 In one substrate 23, opposing sides 26a and 26b are formed at an angle of 120 degrees with respect to the vertex P1. Among the three non-opposing sides 27a, 27b, 27c, the first non-opposing side 27a is formed at an angle of 90 degrees through the apex P2 between it and the first opposing side 26a, and The non-opposing side 27b is formed at an angle of 90 degrees through the apex P3 between it and the second opposing side 26b, and the third non-opposing side 27c is formed between each non-opposing side 27a, 27b. The vertices P4 and P5 are formed at an angle of 120 degrees between the vertices P4 and P5.

第３の非対向辺部２７ｃは、基板２３の辺の中で最も長い辺で、正六角形の基板集合体の一辺を成す。第１の非対向辺部２７ａおよび第２の非対向辺部２７ｂは、基板２３の辺の中で最も短い辺であるとともに第３の非対向辺部２７ｃの１／２の長さで、正六角形の基板集合体を形成した際に隣接する２つの基板２３の第１の非対向辺部２７ａと第２の非対向辺部２７ｂとで正六角形の基板集合体の一辺を成す。２つの対向辺部２６ａ，２６ｂは、第１の非対向辺部２７ａおよび第２の非対向辺部２７ｂよりも長く、第３の非対向辺部２７ｃよりも短い。 The third non-opposing side portion 27c is the longest side among the sides of the substrate 23, and forms one side of the regular hexagonal substrate assembly. The first non-opposing side 27a and the second non-opposing side 27b are the shortest sides of the sides of the substrate 23 and have a length of 1/2 of the third non-opposing side 27c. When a square substrate assembly is formed, the first non-opposing side 27a and the second non-opposing side 27b of two adjacent substrates 23 form one side of the regular hexagonal substrate assembly. The two opposing sides 26a and 26b are longer than the first non-opposing side 27a and the second non-opposing side 27b, and shorter than the third non-opposing side 27c.

なお、基板２３の形状は、他の基板２３と対向しない外側辺が３つの非対向辺部２７ａ，２７ｂ，２７ｃで形成される五角形に限らず、その外側辺が円弧形状とする扇形や、三角形状とする菱形などに形成されていてもよい。その外側辺が円弧形状とする扇形の基板２３を用いることで、外形が円形状の基板集合体に形成してもよい。あるいは、基板集合体の外形は、六角形以外の多角形でもよい。また、光源モジュール２２ａ，２２ｂ，２２ｃの基板２３の形状は、中心点Ｏを中心とする周方向に３つに分割された形状に限らず、２つに分割された形状でもよく、あるいは４つ以上に分割された形状でもよい。 Note that the shape of the substrate 23 is not limited to a pentagon whose outer side that does not face other substrates 23 is formed by three non-opposing sides 27a, 27b, and 27c, but may also be a fan shape whose outer side is an arc shape, or a triangular shape. It may be formed into a diamond shape or the like. By using a fan-shaped substrate 23 whose outer side is arc-shaped, a substrate assembly having a circular outer shape may be formed. Alternatively, the outer shape of the substrate assembly may be a polygon other than a hexagon. Further, the shape of the substrate 23 of the light source modules 22a, 22b, 22c is not limited to a shape divided into three in the circumferential direction centering on the center point O, but may be divided into two or four. The shape may be divided into more than one.

基板２３は、単層基板または片面基板であり、例えばアルミニウムなどの金属材料や、例えばガラスエポキシなどの樹脂材料や、例えば酸化アルミニウムや窒化アルミニウムなどのセラミックスなどの無機材料で形成されたベース板を有し、このベース板の前面側に配線パターンが形成されている。配線パターンには、各発光素子２４を実装する複数の発光素子実装パッド部と、基板２３の周辺部（非対向辺部２７ａ，２７ｂ側）に設けられる一対のコネクタ実装パッド部と、発光素子２４の種類毎の発光素子実装パッド部を直列または直並列に接続するとともに両端が一対のコネクタ実装パッド部に接続される配線部と、を含んでいる。配線部は複数の発光素子実装パッド部の間や、基板２３の周辺領域などに沿って配線されるが、一部の配線部が交差する交差箇所が存在する場合、その交差箇所では下層の配線部上に設けられるジャンパー用絶縁層に交差する上層の配線部が設けられ、配線部同士が絶縁されている。 The substrate 23 is a single-layer substrate or a single-sided substrate, and includes a base plate made of a metal material such as aluminum, a resin material such as glass epoxy, or an inorganic material such as ceramics such as aluminum oxide or aluminum nitride. A wiring pattern is formed on the front side of this base plate. The wiring pattern includes a plurality of light emitting element mounting pad parts on which each light emitting element 24 is mounted, a pair of connector mounting pad parts provided on the peripheral part of the board 23 (on the non-opposed sides 27a and 27b side), and a plurality of light emitting element mounting pad parts for mounting each light emitting element 24. The wiring section connects the light emitting element mounting pad sections of each type in series or in series and parallel, and has both ends connected to a pair of connector mounting pad sections. The wiring portions are routed between multiple light emitting element mounting pad portions and along the peripheral area of the substrate 23. However, if there is an intersection where some of the wiring portions intersect, the lower layer wiring is routed at that intersection. An upper layer wiring section is provided that intersects with the jumper insulating layer provided on the jumper insulating layer, and the wiring sections are insulated from each other.

基板２３は、発光素子２４およびコネクタ２５が実装される前面側とは反対の他面である背面側が、放熱器１１の光源取付面２０に面接触されて熱的に接続されるように取り付けられる。この際、図２のように、第２の光源モジュール２２ｂの第３の非対向辺部２７ｃが放熱器１１の光源取付面部２０の一辺である第１の辺２０ａに平行に対向するように配設され、第１の光源モジュール２２ａの第１の非対向辺部２７ａおよび第３の光源モジュール２７ｃの第２の非対向辺部２７ｂが放熱器１１の光源取付面部２０の第１の辺２０ａとは反対の第２の辺２０ｂに平行に対向するように配設され、第１の光源モジュール２２ａの頂点Ｐ５および第３の光源モジュール２２ｃの頂点Ｐ４が放熱器１１の光源取付面２０の各辺２０ａ，２０ｂに交差する第３の辺２０ｃおよび第４の辺２０ｄに最も接近するように配設される。なお、照明装置１０がスポットライトの場合、放熱器１１の光源取付面２０の第１の辺２０ａは上辺、第２の辺２０ｂは下辺、第３の辺２０ｃは左辺、第４の辺２０ｄは右辺となる。 The substrate 23 is attached so that the back side, which is the other side opposite to the front side on which the light emitting element 24 and the connector 25 are mounted, is in surface contact with the light source mounting surface 20 of the radiator 11 and is thermally connected. . At this time, as shown in FIG. 2, the third non-opposing side 27c of the second light source module 22b is arranged parallel to and opposite to the first side 20a, which is one side of the light source mounting surface 20 of the radiator 11. The first non-opposing side 27a of the first light source module 22a and the second non-opposing side 27b of the third light source module 27c are aligned with the first side 20a of the light source mounting surface 20 of the radiator 11. are arranged to face parallel to the opposite second side 20b, and the vertex P5 of the first light source module 22a and the vertex P4 of the third light source module 22c are on each side of the light source mounting surface 20 of the radiator 11. It is arranged so as to be closest to the third side 20c and the fourth side 20d that intersect 20a and 20b. Note that when the lighting device 10 is a spotlight, the first side 20a of the light source mounting surface 20 of the radiator 11 is the top side, the second side 20b is the bottom side, the third side 20c is the left side, and the fourth side 20d is the top side. This will be the right side.

第１の光源モジュール２２ａの第２の非対向辺部２７ｂおよび第２の光源モジュール２２ｂの第１の非対向辺部２７ａは、放熱器１１の光源取付面２０の第１の辺２０ａと第３の辺２０ｃとの成す角部域に間隔を空けて対向配置され、その角部域との間に配線スペース２８が形成される。同様に、第２の光源モジュール２２ｂの第２の非対向辺部２７ｂおよび第３の光源モジュール２２ｃの第１の非対向辺部２７ａは、放熱器１１の光源取付面２０の第１の辺２０ａと第４の辺２０ｄとの成す角部域に間隔を空けて対向配置され、その角部域との間に配線スペース２８が形成される。配線スペース２８は、図２に示す正面視において、光源部１７の、放熱器１１と光源装置１２とが重ならない領域を指す。本構成によって配線スペース２８を広く設けることが可能となり、配線スペース２８に配置する配線の自由度を高くすることが可能となる。 The second non-opposing side 27b of the first light source module 22a and the first non-opposing side 27a of the second light source module 22b are connected to the first side 20a of the light source mounting surface 20 of the radiator 11 and the third non-opposing side 27b of the first light source module 22a. A wiring space 28 is formed between the corner region formed by the side 20c and the corner region 20c at a distance from each other. Similarly, the second non-opposing side 27b of the second light source module 22b and the first non-opposing side 27a of the third light source module 22c are the same as the first side 20a of the light source mounting surface 20 of the radiator 11. and the fourth side 20d, facing each other with an interval between them, and a wiring space 28 is formed between the corner area and the fourth side 20d. The wiring space 28 refers to a region of the light source section 17 where the heat radiator 11 and the light source device 12 do not overlap in the front view shown in FIG. With this configuration, it becomes possible to provide a wide wiring space 28, and it becomes possible to increase the degree of freedom in wiring arranged in the wiring space 28.

光源モジュール２２ａ，２２ｂ，２２ｃは、外形寸法や、発光素子２４の種類および実装位置が同じ光源モジュールを用いることで、共通化できる。光源モジュール２２ａ，２２ｂ，２２ｃは、共通化の観点から同一の光源モジュールであることが好ましいが、異なる光源モジュールであってもよい。ここでの異なる光源モジュールとは、外形寸法や、発光素子２４の実装位置が同じだが、例えば、発光素子２４の種類が異なったり、配線パターンが異なったり、コネクタ２５の位置が異なったりする光源モジュールである。 The light source modules 22a, 22b, and 22c can be made common by using light source modules that have the same external dimensions, the same type of light emitting element 24, and the same mounting position. The light source modules 22a, 22b, and 22c are preferably the same light source module from the viewpoint of common use, but may be different light source modules.

そして、照明装置１０においては、投影する光色に応じて、電源ユニットにより発光素子２４の種類の系統毎に配線部材３１，３２を通じて光源装置１２の光源モジュール２２ａ，２２ｂ，２２ｃに点灯電力を供給し、発光素子２４を点灯させる。点灯した発光素子２４の光がアパーチャ１４に対向する拡散板１３の有効領域に入射され、拡散板１３によって各色の光が混色されて疑似光源が生成され、この拡散板１３で生成される疑似光源の光が投影レンズ１６により照射面へ照射される。 In the lighting device 10, the power supply unit supplies lighting power to the light source modules 22a, 22b, 22c of the light source device 12 through the wiring members 31, 32 for each type of light emitting element 24 according to the color of light to be projected. Then, the light emitting element 24 is turned on. The light from the lit light emitting element 24 is incident on the effective area of the diffuser plate 13 facing the aperture 14, and the diffuser plate 13 mixes the light of each color to generate a pseudo light source. The light is irradiated onto the irradiation surface by the projection lens 16.

Unlike the light, the colors are not mixed by the diffuser plate 13 and are likely to be projected without being mixed. Therefore, if a non-phosphor light emitting element such as a primary color red light emitting element, a green light emitting element, or a blue light emitting element that does not contain a phosphor is placed at the outermost periphery of the mounting area of the light emitting element 24, color unevenness may occur. Light from non-phosphor light-emitting elements such as primary-color red light-emitting elements, green light-emitting elements, and blue light-emitting elements that do not contain easily recognized phosphors is projected without being mixed, resulting in poor color reproducibility, color unevenness, and Optical properties such as uneven brightness are impaired.

本実施形態の光源装置１２では、発光素子２４の実装領域の最外周部には、蛍光体を含む蛍光体発光素子のみを配置し、発光素子２４の実装領域の最外周部よりも内側の実装位置に、蛍光体を含まない原色系の赤色発光素子、緑色発光素子および青色発光素子などの非蛍光体発光素子を配置している。 In the light source device 12 of this embodiment, only the phosphor light-emitting elements containing fluorescent material are arranged at the outermost periphery of the mounting area of the light-emitting element 24, and the phosphor light-emitting elements containing phosphor are arranged inside the outermost periphery of the mounting area of the light-emitting element 24. Non-phosphor light-emitting elements such as primary color red light-emitting elements, green light-emitting elements, and blue light-emitting elements that do not contain fluorescent substances are arranged at the positions.

このように、発光素子２４の実装領域の最外周部に、蛍光体を含まない原色系の赤色発光素子、緑色発光素子および青色発光素子などの非蛍光体発光素子が配置されないことで、これら蛍光体を含まない原色系の赤色発光素子、緑色発光素子および青色発光素子などの非発光体発光素子からの光が拡散板１３で混色されずに投影されてしまうのを防止でき、色の再現性、色むら、輝度むらなどの光学特性を向上させることができる。 In this way, non-phosphor light-emitting elements such as primary color red light-emitting elements, green light-emitting elements, and blue light-emitting elements that do not contain fluorescent substances are not placed on the outermost periphery of the mounting area of the light-emitting elements 24, so that these fluorescent It is possible to prevent light from non-luminescent light-emitting elements such as primary color red light-emitting elements, green light-emitting elements, and blue light-emitting elements that do not contain a body from being projected on the diffuser plate 13 without being mixed, improving color reproducibility. , optical properties such as color unevenness and brightness unevenness can be improved.

また、原色系の赤色発光素子と、緑色発光素子と、青色発光素子とが隣接して配置されている場合、これら原色系の赤色発光素子と、緑色発光素子と、青色発光素子との色度の差が、非蛍光体発光素子と蛍光体発光素子との色度の差に比べて大きいため、光が拡散板１３で混色されず、色むらとして認識されやすい。 In addition, when a primary color red light emitting element, a green light emitting element, and a blue light emitting element are arranged adjacent to each other, the chromaticity of the primary color red light emitting element, green light emitting element, and blue light emitting element is Since the difference in chromaticity between the non-phosphor light emitting element and the phosphor light emitting element is larger than the difference in chromaticity between the non-phosphor light emitting element and the phosphor light emitting element, the light is not mixed on the diffuser plate 13 and is easily recognized as color unevenness.

本実施形態の光源装置１２では、赤色発光素子と、緑色発光素子と、青色発光素子とは、それぞれ隣接しない位置に配置している。すなわち、赤色発光素子と、緑色発光素子と、青色発光素子とは、それぞれ発光素子２４との色度の差が小さい蛍光体発光素子間においた位置に配置している。 In the light source device 12 of this embodiment, the red light emitting element, the green light emitting element, and the blue light emitting element are arranged at positions that are not adjacent to each other. That is, the red light emitting element, the green light emitting element, and the blue light emitting element are respectively arranged at positions between the phosphor light emitting elements having a small difference in chromaticity from the light emitting element 24.

これにより、隣接する発光素子２４の色度の差を小さくし、拡散板１３での混色を良好にでき、色むらを低減できる。 This reduces the difference in chromaticity between adjacent light emitting elements 24, improves color mixing on the diffuser plate 13, and reduces color unevenness.

また、発光素子２４の点灯時に発生する熱は基板２３から放熱器１１に伝達されて放熱される。 Further, heat generated when the light emitting element 24 is turned on is transmitted from the substrate 23 to the heat radiator 11 and radiated.

このとき、光源装置１２の基板２３を大形の１枚基板で構成した場合、発光素子２４の発熱による基板２３の反りや曲がりなどの変位の影響が大きく、基板２３に実装された発光素子２４などの半田付け箇所にクラックが生じる虞がある。 At this time, if the board 23 of the light source device 12 is configured as a single large board, the effect of displacement such as warping or bending of the board 23 due to heat generation of the light emitting elements 24 is large, and the light emitting elements 23 mounted on the board 23 are There is a risk that cracks may occur at soldered points such as.

本実施形態の光源装置１２では、複数の基板２３を集合して１つの基板集合体を形成しているため、複数の基板２３の１つずつの大きさを１枚基板に比べて小さくすることでき、発光素子２４の発熱による基板２３の反りや曲がりなどの変位の影響を少なくし、基板２３に実装された発光素子２４などの半田付け箇所にクラックが生じるのを抑制できる。 In the light source device 12 of this embodiment, since the plurality of substrates 23 are assembled to form one substrate assembly, the size of each of the plurality of substrates 23 can be made smaller than that of a single substrate. It is possible to reduce the influence of displacement such as warping or bending of the board 23 due to heat generated by the light emitting element 24, and to suppress the occurrence of cracks at the soldered parts of the light emitting element 24 and the like mounted on the board 23.

そして、本実施形態の光源装置１２では、コネクタ２５が基板２３の非対向辺部２７側に配設されるため、複数の基板２３を集合させて１つの基板集合体を形成した場合でも、コネクタ２５に対する配線の自由度が高く、電源ユニットとの間を接続する配線部材３１や、基板２３間を接続する配線部材３２を容易に配線でき、しかも配線部材３１，３２で発光素子２４からの光を遮るようなことも防止できる。 In the light source device 12 of this embodiment, the connector 25 is disposed on the non-opposing side 27 side of the substrate 23, so even when a plurality of substrates 23 are assembled to form one substrate assembly, the connector 25, the wiring member 31 that connects the power supply unit and the wiring member 32 that connects the board 23 can be easily wired. It is also possible to prevent things that would obstruct the

また、発光素子２４は、四角形状の外形の一辺が基板２３の第１の対向辺部２６ａに平行に対向する第１の向きで配設される発光素子２４と、四角形状の外形の一辺が第２の対向辺部２６ｂに平行に対向する第２の向きに配設される発光素子２４と、を備えるため、隣接する基板２３の第１の対向辺部２６ａと第２の対向辺部２６ｂとが対向することで、隣接する基板２３間で隣接する発光素子２４の向きを合わせることができ、基板２３間の繋ぎ目での光特性の変化を抑制できる。 Further, the light emitting element 24 is arranged in a first direction in which one side of the rectangular outer shape faces parallel to the first opposing side 26a of the substrate 23, and the other light emitting element 24 is disposed in a first direction in which one side of the rectangular outer shape faces the first opposing side 26a of the substrate 23. Since the light emitting element 24 is disposed in a second direction facing parallel to the second opposing side 26b, the first opposing side 26a and the second opposing side 26b of the adjacent substrate 23 are provided. By facing each other, the directions of the adjacent light emitting elements 24 can be matched between the adjacent substrates 23, and changes in optical characteristics at the joint between the substrates 23 can be suppressed.

しかも、第２の向きの発光素子２４は、第２の対向辺部２６ｂに最も近い列の位置のみに配設され、残りの位置には全て第１の向きの発光素子２４が配設されるため、隣接する基板２３間で隣接する発光素子２４の向きとともに位置関係などを含めて容易に合わせることができ、基板２３間の繋ぎ目での光特性の変化を抑制できる。 Moreover, the light emitting elements 24 facing the second direction are arranged only in the position of the row closest to the second opposing side 26b, and the light emitting elements 24 facing the first direction are arranged at all the remaining positions. Therefore, the orientation and positional relationship of the adjacent light emitting elements 24 can be easily matched between the adjacent substrates 23, and changes in optical characteristics at the joint between the substrates 23 can be suppressed.

また、照明装置１０は、移動機構１８により、光源部１７が前方または後方に移動し、疑似光源を生成する拡散板１３と投影レンズ１６との間の距離が変化し、照射する光の範囲を変更できる。 Further, in the illumination device 10, the light source unit 17 is moved forward or backward by the moving mechanism 18, and the distance between the diffuser plate 13 that generates a pseudo light source and the projection lens 16 is changed, and the range of light to be irradiated is changed. Can be changed.

この際、基板２３間を接続する配線部材３２は、放熱器１１の光源取付面２０に対向する前方向から見て、放熱器１１の光源取付面２０の領域内に配置され、配線スペース２８や放熱器１１の光源取付面２０から外側にはみ出ることはないため、光源部１７が移動しても配線部材３２が他の部材に引っ掛かるようなことがなく、光源部１７の移動を阻害することがないとともに電気的な断線などの発生を抑制できる。 At this time, the wiring member 32 that connects the substrates 23 is arranged within the area of the light source mounting surface 20 of the radiator 11 when viewed from the front facing the light source mounting surface 20 of the radiator 11, and Since it does not protrude outward from the light source mounting surface 20 of the radiator 11, even if the light source section 17 moves, the wiring member 32 will not get caught on other members, and the movement of the light source section 17 will not be hindered. In addition, the occurrence of electrical disconnections can be suppressed.

基板２３間を接続する配線部材３２に関しては、図４（ａ）～（ｇ）に示すように（図４（ａ）～（ｇ）は光源装置１２の外形と仮想矩形４０との関係をそれぞれ示す概略正面図を示す）、正面視で光源装置１２を包含し、光源装置１２の基板２３の正面の面積の総和よりも大きい面積を有する仮想矩形４０であって、仮想矩形４０の少なくとも一辺と、光源装置１２の外形の頂点もしくは辺と、が重なる仮想矩形４０を定義した場合、配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１（配線スペース２８）に引き回される関係を有する。ここでの引き回すとは、領域４１内に配線部材３２の少なくとも一部が存在していることをいう。なお、領域４１内に配線部材３２の全てが存在することが好ましい。この場合、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に対応して隣接する基板２３間の分割部が配置されることで、基板２３間を接続する配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に引き回される。 Regarding the wiring member 32 that connects the substrates 23, as shown in FIGS. (shows a schematic front view), a virtual rectangle 40 that includes the light source device 12 in a front view and has an area larger than the sum of the areas of the front surfaces of the substrates 23 of the light source device 12, and at least one side of the virtual rectangle 40 and , when defining a virtual rectangle 40 that overlaps with the apex or side of the external shape of the light source device 12, the wiring member 32 is formed in an area 41 (wiring space 28 ). Routing here means that at least a portion of the wiring member 32 exists within the region 41. Note that it is preferable that all of the wiring members 32 exist within the region 41. In this case, the wiring member 32 connecting the substrates 23 is arranged so that the dividing portion between the adjacent substrates 23 corresponds to the area 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40. is routed to a region 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40 .

図４（ａ）に、光源装置１２の外形が三角形の場合を示し、仮想矩形４０の一の辺は、光源装置１２の外形の１つの辺と重なり、かつ、仮想矩形４０の一の辺と対向する他の辺は、光源装置１２の外形の頂点１つと重なる関係にある。この関係により、配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に引き回される。なお、ここでの重なるとは、仮想矩形４０の辺と、光源装置１２の外形の辺と、が一致する構成も含まれるし、仮想矩形４０の辺の少なくとも一部と、光源装置１２の外形の辺もしくは頂点と、が重なる構成も含まれる。以降においても同じである。 FIG. 4A shows a case where the outer shape of the light source device 12 is triangular, and one side of the virtual rectangle 40 overlaps with one side of the outer shape of the light source device 12, and one side of the virtual rectangle 40 overlaps with one side of the outer shape of the light source device 12. The other opposing sides overlap one vertex of the outer shape of the light source device 12 . Due to this relationship, the wiring member 32 is routed to a region 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40. Note that overlapping here includes a configuration in which the sides of the virtual rectangle 40 and the sides of the outer shape of the light source device 12 match, and also includes a configuration in which the sides of the virtual rectangle 40 and the outer shape of the light source device 12 match. This also includes configurations in which the edges or vertices overlap. The same applies thereafter.

図４（ｂ）に、光源装置１２の外形が四角形の場合を示し、仮想矩形４０の全ての辺は、それぞれ光源装置１２の外形の異なる頂点１つと重なる関係にある（ただし、仮想矩形の面積＞光源装置１２の面積の関係を有する）。この関係により、配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に引き回される。 FIG. 4B shows a case where the outer shape of the light source device 12 is a quadrilateral, and all sides of the virtual rectangle 40 overlap one different vertex of the outer shape of the light source device 12 (however, the area of the virtual rectangle >the area of the light source device 12). Due to this relationship, the wiring member 32 is routed to a region 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40.

図４（ｃ）に、光源装置１２の外形が五角形の場合を示し、仮想矩形４０の１つの辺は、光源装置１２の外形の１つの辺と重なり、かつ、仮想矩形４０の他の３つの辺は、それぞれ光源装置１２の外形の異なる頂点１つと重なる関係にある。この関係により、配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に引き回される。 FIG. 4C shows a case where the outer shape of the light source device 12 is pentagonal, and one side of the virtual rectangle 40 overlaps with one side of the outer shape of the light source device 12, and the other three sides of the virtual rectangle 40 overlap with one side of the outer shape of the light source device 12. Each side has a relationship of overlapping with one different vertex of the outer shape of the light source device 12. Due to this relationship, the wiring member 32 is routed to a region 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40.

光源装置１２の外形が五角形以上の奇数角形（２×ｎ＋１ （ｎ＝２以上の整数））の場合、例えば七角形、九角形、十一角形…の場合、図４（ｃ）に示した五角形と同様の関係となる。ただし、仮想矩形４０の他の３つの辺は、それぞれ光源装置１２の外形の異なる頂点１つと重なる関係にある。つまり、この場合、光源装置１２は、外形に、仮想矩形４０の辺と重ならない頂点を備える構成となる。 When the outer shape of the light source device 12 is an odd-numbered polygon of pentagon or more (2×n+1 (n=integer of 2 or more)), for example, heptagon, nonagon, decagon, etc., the pentagon shown in FIG. 4(c) is used. The relationship is similar to . However, the other three sides of the virtual rectangle 40 are in a relationship where they each overlap one different vertex of the external shape of the light source device 12. That is, in this case, the light source device 12 has a configuration in which the external shape includes vertices that do not overlap with the sides of the virtual rectangle 40.

図４（ｄ）に、上述した実施形態のように、光源装置１２の外形が六角形の場合を示し、仮想矩形４０の上下に対向する２つの辺は、それぞれ光源装置１２の外形の異なる辺１つと重なり、かつ、仮想矩形４０の他の左右に対向する２つの辺は、それぞれ光源装置１２の外形の異なる頂点１つと重なる関係にある。この関係により、配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に引き回される。 FIG. 4D shows a case where the outer shape of the light source device 12 is hexagonal as in the above-described embodiment, and two vertically opposing sides of the virtual rectangle 40 are different sides of the outer shape of the light source device 12. The other two left and right sides of the virtual rectangle 40 that overlap with one other and which are opposite to each other on the left and right are in a relationship that each overlaps with one different vertex of the outer shape of the light source device 12 . Due to this relationship, the wiring member 32 is routed to a region 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40.

また、光源装置１２の外形が六角形以上の偶数角形であって、Ｎ（６＋４ｎ （ｎ＝１以上の整数））角形の場合、例えば十角形、十四角形、十八角形…の場合、図４（ｄ）に示した六角形と同様の関係となる。この場合も、光源装置１２は、仮想矩形４０の辺と重ならない頂点を備える構成となる。 In addition, when the outer shape of the light source device 12 is an even-numbered polygon of hexagon or more, and is an N (6+4n (n=an integer of 1 or more)) polygon, for example, a decagon, a decagon, a decagon, an octagon, etc., FIG. The relationship is similar to that of the hexagon shown in (d). In this case as well, the light source device 12 is configured to include vertices that do not overlap with the sides of the virtual rectangle 40.

例えば、図４（ｅ）に、光源装置１２の外形が十角形の場合を示し、仮想矩形４０の上下に対向する２つの辺は、それぞれ光源装置１２の外形の異なる辺１つと重なり、かつ、仮想矩形４０の他の左右に対向する２つの辺は、それぞれ光源装置１２の外形の異なる頂点１つと重なる関係にある。 For example, FIG. 4E shows a case where the outer shape of the light source device 12 is a decagon, and two vertically opposing sides of the virtual rectangle 40 each overlap one side of the light source device 12 with a different outer shape, and The other two left and right opposing sides of the virtual rectangle 40 are in a relationship where they each overlap one different vertex of the outer shape of the light source device 12.

光源装置１２の外形がＮ（６＋４ｎ （ｎ＝１以上の整数））角形においては、上下に対向する２つの辺が、それぞれ仮想矩形４０の上下に対向する２つの辺と重なるので、残りの辺の数はＮ－２で、光源装置１２の外形において左右側に配置される辺の数（Ｎ／２－１）は均等となり、この光源装置１２の外形において左右側に配置される辺の数（Ｎ／２－１）の値が偶数となる場合は、光源装置１２の外形において左右側に配置される辺が、仮想矩形４０の左右側に対向する辺と重なることはない。 When the outer shape of the light source device 12 is N (6+4n (n=an integer of 1 or more)), the two vertically opposing sides overlap the two vertically opposing sides of the virtual rectangle 40, so the remaining sides are The number of sides is N-2, and the number of sides (N/2-1) arranged on the left and right sides of the outer shape of the light source device 12 is equal, and the number of sides arranged on the left and right sides of the outer shape of the light source device 12 is equal. When the value of (N/2-1) is an even number, the sides arranged on the left and right sides of the outer shape of the light source device 12 do not overlap the sides of the virtual rectangle 40 that are opposite to the left and right sides.

また、図４（ｆ）に、光源装置１２の外形が八角形の場合を示し、仮想矩形４０の４つの辺は、それぞれ光源装置１２の外形の辺１つと重なる関係にある。この関係により、配線部材３２は、光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１に引き回される。 Further, FIG. 4F shows a case where the outer shape of the light source device 12 is an octagon, and each of the four sides of the virtual rectangle 40 overlaps one side of the outer shape of the light source device 12. Due to this relationship, the wiring member 32 is routed to a region 41 surrounded by the non-opposed side portion 27 of the light source device 12 and the virtual rectangle 40.

光源装置１２の外形が六角形以上の偶数角形であって、（６×４ｎ－２ （ｎ＝１以上の整数））角形の場合、例えば八角形、十二角形、十六角形…の場合、図４（ｆ）に示した八角形と同様の関係となる。 When the outer shape of the light source device 12 is an even-numbered polygon of hexagon or more, and is (6×4n-2 (n=an integer of 1 or more)), for example, an octagon, a dodecagon, a hexagon, etc., The relationship is similar to that of the octagon shown in FIG. 4(f).

例えば、図４（ｇ）に、光源装置１２の外形が十二角形の場合を示し、仮想矩形４０の４つの辺は、それぞれ光源装置１２の外形の異なる辺１つと重なる関係にある。 For example, FIG. 4G shows a case where the outer shape of the light source device 12 is a dodecagon, and each of the four sides of the virtual rectangle 40 is in a relationship that overlaps with one different side of the outer shape of the light source device 12.

このように、正面視で光源装置１２を包含し、光源装置１２の基板２３の正面の面積の総和よりも大きい面積を有する仮想矩形４０であって、仮想矩形４０の少なくとも一辺と、光源装置１２の外形の頂点もしくは辺と、が重なる仮想矩形４０を定義した場合、配線部材３２は、少なくとも光源装置１２の非対向辺部２７と仮想矩形４０とで囲まれる領域４１（配線スペース２８）に引き回される関係を有することで、基板２３間を接続する配線部材３２の引き回しの自由度を高くすることが可能となる。なお、仮想矩形４０は、光源装置１２を包含し、かつ、光源装置１２の基板２３の正面の面積の総和よりも大きい面積を有し、かつ、仮想矩形４０の少なくとも一辺と、光源装置１２の外形の頂点もしくは辺と、が重なる、条件を満たしつつ最小の面積となるように構成されることが望ましい。 In this way, the virtual rectangle 40 includes the light source device 12 in a front view and has an area larger than the total area of the front surface of the substrate 23 of the light source device 12, and the virtual rectangle 40 includes at least one side of the virtual rectangle 40 and the light source device 12. If a virtual rectangle 40 is defined that overlaps with the vertices or sides of the outer shape of By having a rotational relationship, it becomes possible to increase the degree of freedom in routing the wiring member 32 that connects the substrates 23. The virtual rectangle 40 includes the light source device 12, has an area larger than the total area of the front surface of the substrate 23 of the light source device 12, and has at least one side of the virtual rectangle 40 and the light source device 12. It is desirable that the configuration is such that the area overlaps with the vertices or edges of the external shape, and the area is the minimum while satisfying the condition.
