　特許文献１の技術の場合、パネル状の発光装置の中心を通り且つ当該発光装置に対して直交する回転中心軸周りの発光装置の角度を、取付ベース部材に対して所定の回転角度に配置したときと、当該所定の回転角度から１８０度回転させたときの、何れでも、発光装置を取付ベース部材に取り付け可能であると思われる。このため、取付ベース部材に対して発光装置を誤った取り付け方で取り付けてしまう可能性がある。 In the case of the technique of Patent Document 1, the angle of the light emitting device around the rotation center axis that passes through the center of the panel-shaped light emitting device and is orthogonal to the light emitting device is arranged at a predetermined rotation angle with respect to the mounting base member.

An example is given below.

It is a sectional side view which shows a state. FIG. 2 is a plan view of the light emitting device 100 according to the embodiment. FIG. 3 is a plan view of the mounting base member 1 to which the light emitting device 100 according to the embodiment is mounted. 1A and 1B are cross-sectional views taken along the line AA in FIGS. The light emitting device 100 can be used as a light source of, for example, a display, a lighting device, or an optical communication device.
　本実施形態に係る発光装置１００は、発光素子２と、発光素子２が一方の面に固定された固定板３と、を備える。固定板３において発光素子２が固定された面とは反対側の面には、凹部と凸部とのうちの少なくとも何れか一方を含む凹凸構造４が形成されている。凹凸構造４は、固定板３に対して直交する方向に固定板３を見たときの固定板３の中心３２を通り且つ固定板３に対して直交する回転中心軸３１を基準として、非回転対称形である。 The light emitting device 100 according to this embodiment includes a light emitting element 2 and a fixed plate 3 on which the light emitting element 2 is fixed to one surface. A concavo-convex structure 4 including at least one of a concave portion and a convex portion is formed on the surface of the fixing plate 3 opposite to the surface on which the light emitting element 2 is fixed. The concavo-convex structure 4 is non-rotating on the basis of the rotation center axis 31 that passes through the center 32 of the fixing plate 3 when viewed in the direction orthogonal to the fixing plate 3 and is orthogonal to the fixing plate 3. It is symmetrical.
　以下においては、説明を簡単にするため、発光装置１００および取付ベース部材１の各構成要素の位置関係（上下関係等）が各図に示す関係であるものとして説明を行う。ただし、この説明における位置関係は、発光装置１００および取付ベース部材１の使用時の位置関係とは無関係である。 Hereinafter, in order to simplify the description, the description will be made assuming that the positional relationship (vertical relationship, etc.) of each component of the light emitting device 100 and the mounting base member 1 is the relationship shown in each drawing. However, the positional relationship in this description is irrelevant to the positional relationship when the light emitting device 100 and the mounting base member 1 are used.
　発光装置１００は、平板なパネル状に形成されている。一例として、発光装置１００の平面形状は、矩形状であることが挙げられるが、その他の多角形状（五角形、六角形など）でも良いし、円形、楕円形、長円形などでも良い。図１および図２には、発光装置１００の平面形状が正方形である例を示している。また、この例では、固定板３の平面形状も正方形である。 The light emitting device 100 is formed in a flat panel shape. As an example, the planar shape of the light emitting device 100 may be a rectangular shape, but may be other polygonal shapes (pentagonal, hexagonal, etc.), circular, elliptical, oval or the like. 1 and 2 show an example in which the planar shape of the light emitting device 100 is a square. In this example, the planar shape of the fixing plate 3 is also square.
　発光装置１００は、発光素子２を有している。この発光素子２は、例えば、有機ＥＬ素子であることが挙げられる。ただし、発光装置１００が有する発光素子は、有機ＥＬ素子に限らない。例えば、発光素子は、ＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）と導光板とを組み合わせて構成されていても良いし、複数のＬＥＤをアレイ状に配列することにより構成されていても良い。また、発光素子は、無機ＥＬ素子や冷陰極管であっても良い。発光素子２の一方の面（図１の下面）は、光を放射する発光面２ａとなっている。 The light emitting device 100 has a light emitting element 2. The light emitting element 2 is, for example, an organic EL element. However, the light emitting element included in the light emitting device 100 is not limited to the organic EL element. For example, the light emitting element may be configured by combining an LED (Light Emitting Diode) and a light guide plate, or may be configured by arranging a plurality of LEDs in an array. Further, the light emitting element may be an inorganic EL element or a cold cathode tube. One surface (the lower surface in FIG. 1) of the light emitting element 2 is a light emitting surface 2a that emits light.
　発光装置１００は、平板状の固定板３の一方の面（図１の下面）に発光素子２が固定されることにより構成されている。発光素子２を発光させる制御を行う制御部（図７（ｃ）で後述する制御部６等）は、発光素子２および固定板３と一体に設けられていても良いし、この制御部は、発光素子２および固定板３とは別体に配置されていても良い。 The light emitting device 100 is configured by fixing the light emitting element 2 to one surface (the lower surface in FIG. 1) of the flat fixing plate 3. A control unit (such as a control unit 6 described later with reference to FIG. 7C) that controls the light emitting element 2 to emit light may be provided integrally with the light emitting element 2 and the fixing plate 3. The light emitting element 2 and the fixing plate 3 may be arranged separately.
　取付ベース部材１は、一例として図１に示すような筐体形状であることが挙げられる。この場合、取付ベース部材１は、例えば、下方に向けて開放した内部空間を画定している。この内部空間は、開口１ｂを介して、外部の空間と連通している。この内部空間の少なくとも一部は、発光装置１００が設置される設置領域１ａである。この場合、取付ベース部材１は、天板１１と、天板１１の周縁部から垂下している側壁部１２と、を有する。一例として、天板１１の平面形状は、矩形状であることが挙げられるが、その他の多角形状（五角形、六角形など）でも良いし、円形、楕円形、長円形などでも良い。天板１１の下面１１ａは、設置領域１ａに設置された状態の発光装置１００の固定板３と対向する。また、側壁部１２は、枠状（筒状）に形成されていても良いし、天板１１の周縁部の一部分からのみ垂下する形状であっても良い。なお、取付ベース部材１の平面形状は、発光装置１００の平面形状に対して相似形であっても良いし、取付ベース部材１の平面形状と発光装置１００の平面形状とに相関が無くても良い。図１および図３には、取付ベース部材１の平面形状が正方形である例を示している。また、この例では、取付ベース部材１の内部空間の平面形状も正方形である。 The mounting base member 1 has a housing shape as shown in FIG. 1 as an example. In this case, the attachment base member 1 defines, for example, an internal space opened downward. This internal space communicates with the external space through the opening 1b. At least a part of the internal space is an installation area 1a where the light emitting device 100 is installed. In this case, the mounting base member 1 includes a top plate 11 and side wall portions 12 that hang from the peripheral edge of the top plate 11. As an example, the planar shape of the top plate 11 may be a rectangular shape, but may be other polygonal shapes (pentagonal, hexagonal, etc.), circular, elliptical, oval or the like. The lower surface 11a of the top plate 11 faces the fixed plate 3 of the light emitting device 100 in a state installed in the installation area 1a. Further, the side wall portion 12 may be formed in a frame shape (tubular shape), or may have a shape that hangs down only from a part of the peripheral edge portion of the top plate 11. Note that the planar shape of the mounting base member 1 may be similar to the planar shape of the light emitting device 100, or even if there is no correlation between the planar shape of the mounting base member 1 and the planar shape of the light emitting device 100. good. 1 and 3 show an example in which the mounting base member 1 has a square planar shape. In this example, the planar shape of the internal space of the mounting base member 1 is also a square.
　取付ベース部材１の天板１１の下面１１ａには、固定板３の凹凸構造４と嵌合する凹凸構造５が形成されている。凹凸構造５は、凸部と凹部とのうちの少なくとも何れか一方を含んで構成されている。 A concavo-convex structure 5 that fits with the concavo-convex structure 4 of the fixing plate 3 is formed on the lower surface 11 a of the top plate 11 of the mounting base member 1. The concavo-convex structure 5 includes at least one of a convex portion and a concave portion.
　例えば、図１に示すように、凹凸構造４は複数の凹部４１を含んで構成されている。一例として、図２に示すように、３つの凹部４１により凹凸構造４が構成されていることが挙げられる。これら凹部４１は、例えば、二等辺三角形等の正三角形以外の三角形の各頂点に配置されている。例えば、各凹部４１は平面視円形である。 For example, as shown in FIG. 1, the concavo-convex structure 4 includes a plurality of concave portions 41. As an example, as shown in FIG. 2, the concavo-convex structure 4 is constituted by three concave portions 41. These concave portions 41 are arranged at the vertices of a triangle other than an equilateral triangle such as an isosceles triangle, for example. For example, each recess 41 is circular in plan view.
　また、凹凸構造５は、例えば図１に示すように、複数の凸部５１を含んで構成されている。一例として、図３に示すように、３つの凸部５１により凹凸構造５が構成されていることが挙げられる。これら凸部５１は、それぞれ凹部４１と対応する位置に配置されている。各凸部５１は平面視円形である。 Further, as shown in FIG. 1, for example, the concavo-convex structure 5 includes a plurality of convex portions 51. As an example, as shown in FIG. 3, the concavo-convex structure 5 is constituted by three convex portions 51. These convex portions 51 are arranged at positions corresponding to the concave portions 41, respectively. Each convex portion 51 is circular in plan view.
　発光装置１００を取り付けベース部材１に取り付ける際には、固定板３の凹凸構造４と取付ベース部材１の凹凸構造５とを相互に嵌合させる（図１（ｂ））。このため、取付ベース部材１に対するパネル状の発光装置１００の回転角度を、一義的な角度に設定したときにのみ、発光装置１００を取付ベース部材１に取り付けることができる。なぜなら、この一義的な角度以外の場合には、凹凸構造４と凹凸構造５とが嵌合しないためである。 When attaching the light emitting device 100 to the attachment base member 1, the uneven structure 4 of the fixing plate 3 and the uneven structure 5 of the attachment base member 1 are fitted to each other (FIG. 1B). For this reason, the light emitting device 100 can be attached to the mounting base member 1 only when the rotation angle of the panel-like light emitting device 100 with respect to the mounting base member 1 is set to a unique angle. This is because the concavo-convex structure 4 and the concavo-convex structure 5 do not fit in cases other than this unique angle.
　なお、取付ベース部材１は、該取付ベース部材１に発光装置１００が取り付けられた際に、取付ベース部材１を発光装置１００に対して固定するための固定部（図示略）を有している。これにより、凹凸構造４と凹凸構造５とを相互に嵌合した状態に維持することができるとともに、発光装置１００が取付ベース部材１に取り付けられた状態に維持することができる。取付ベース部材１に対する発光装置１００の固定方法は特に限定しない。例えば、係り止め、ネジ止めなどでも良いし、発光装置１００を保持する保持部材を取付ベース部材１が有していても良い。また、取付ベース部材１に発光装置１００が取り付けられた際に、発光装置１００と取付ベース部材１の天板１１や側壁部１２に発光装置１００が接触しても良いし、接触しなくても良い。 The attachment base member 1 has a fixing portion (not shown) for fixing the attachment base member 1 to the light emitting device 100 when the light emitting device 100 is attached to the attachment base member 1. . Thereby, while being able to maintain the uneven structure 4 and the uneven structure 5 in the mutually fitted state, the light-emitting device 100 can be maintained in the state attached to the attachment base member 1. The method for fixing the light emitting device 100 to the mounting base member 1 is not particularly limited. For example, locking or screwing may be used, and the mounting base member 1 may have a holding member that holds the light emitting device 100. Further, when the light emitting device 100 is attached to the attachment base member 1, the light emitting device 100 may or may not contact the light emitting device 100 and the top plate 11 or the side wall portion 12 of the attachment base member 1. good.
　図４は発光素子２が有機ＥＬ素子である場合の有機ＥＬ素子の構造の一例を示す断面図である。有機ＥＬ素子は、例えば、透光性基板１１０と、透光性の第１電極１３０と、有機機能層１４０と、第２電極１５０と、を有する。第１電極１３０は、透光性基板１１０の一方の面側（図４において下面側）に配置されている。有機機能層１４０は、第１電極１３０を基準として透光性基板１１０とは反対側（図４において下側）に配置されている。第２電極１５０は、有機機能層１４０を基準として第１電極１３０とは反対側（図４において下側）に配置されている。なお、透光性基板１１０と第１電極１３０とは相互に接していても良いし、それらの間に他の層が存在していても良い。同様に、第１電極１３０と有機機能層１４０とは相互に接していても良いし、それらの間に他の層が存在していても良い。同様に、有機機能層１４０と第２電極１５０とは相互に接していても良いし、それらの間に他の層が存在していても良い。また、第２電極１５０の下面には必要に応じて封止層を形成しても良い。 FIG. 4 is a cross-sectional view showing an example of the structure of the organic EL element when the light emitting element 2 is an organic EL element. The organic EL element includes, for example, a translucent substrate 110, a translucent first electrode 130, an organic functional layer 140, and a second electrode 150. The first electrode 130 is disposed on one surface side (the lower surface side in FIG. 4) of the translucent substrate 110. The organic functional layer 140 is disposed on the opposite side (lower side in FIG. 4) from the translucent substrate 110 with respect to the first electrode 130. The second electrode 150 is disposed on the opposite side (lower side in FIG. 4) from the first electrode 130 with respect to the organic functional layer 140. Note that the translucent substrate 110 and the first electrode 130 may be in contact with each other, or another layer may exist between them. Similarly, the first electrode 130 and the organic functional layer 140 may be in contact with each other, or another layer may exist between them. Similarly, the organic functional layer 140 and the second electrode 150 may be in contact with each other, or other layers may exist between them. Further, a sealing layer may be formed on the lower surface of the second electrode 150 as necessary.
　透光性基板１１０は、ガラスや樹脂などの透光性を有する材料からなる板状部材である。例えば、透光性基板１１０の上面、すなわち透光性基板１１０における有機機能層１４０とは反対側の面は、平坦な光取り出し面（上記の発光面２ａ）となっている。この光取り出し面は、光放出空間を充たす空気（屈折率１）と接している。なお、透光性基板１１０の上面には、光拡散フィルムなどの光取り出しフィルムが貼り付けられており、この光取り出しフィルムの上面が光取り出し面（上記の発光面２ａ）を構成していても良い。 The translucent substrate 110 is a plate-like member made of a translucent material such as glass or resin. For example, the upper surface of the translucent substrate 110, that is, the surface of the translucent substrate 110 opposite to the organic functional layer 140 is a flat light extraction surface (the light emitting surface 2a). This light extraction surface is in contact with air (refractive index 1) filling the light emission space. Note that a light extraction film such as a light diffusion film is attached to the upper surface of the translucent substrate 110, and the upper surface of the light extraction film constitutes a light extraction surface (the light emitting surface 2a). good.
　第１電極１３０は、例えばＩＴＯ（Ｉｎｄｉｕｍ　Ｔｉｎ　Ｏｘｉｄｅ）やＩＺＯ（Ｉｎｄｉｕｍ　Ｚｉｎｃ　Ｏｘｉｄｅ）などの金属酸化物導電体からなる透明電極とすることができる。ただし、第１電極１３０は、光が透過する程度に薄い金属薄膜であっても良い。有機機能層１４０は、少なくとも発光層を含んで構成されている。第２電極１５０は、例えば、ＡｌやＡｇなどの金属膜からなる反射電極である。第２電極１５０は、有機機能層１４０から第２電極１５０側に向かう光を、透光性基板１１０側に向けて反射する。 The first electrode 130 may be a transparent electrode made of a metal oxide conductor such as ITO (Indium Tin Oxide) or IZO (Indium Zinc Oxide). However, the first electrode 130 may be a metal thin film that is thin enough to transmit light. The organic functional layer 140 includes at least a light emitting layer. The second electrode 150 is a reflective electrode made of a metal film such as Al or Ag. The second electrode 150 reflects light traveling from the organic functional layer 140 toward the second electrode 150 toward the translucent substrate 110.

The translucent substrate 110, the first electrode 130, and the organic functional layer 140 all transmit at least part of the light emitted from the light emitting layer of the organic functional layer 140. Part of the light emitted from the light emitting layer is emitted (extracted) from the light extraction surface of the light-transmitting substrate 110 to the outside of the light emitting device 100 (that is, the light emission space).

That is, the organic functional layer 140 is an organic electroluminescence light emitting layer. Note that instead of the hole injection layer 141 and the hole transport layer 142, one layer having the functions of these two layers may be provided. Similarly, instead of the electron transport layer 144 and the electron injection layer 145, one layer having the functions of these two layers may be provided.
　発光層１４３は、例えば赤色の光を発光する層、青色の光を発光する層、黄色の光を発光する層、又は緑色の光を発光する層である。この場合、平面視において、赤色の光を発光する発光層１４３を有する領域、緑色の光を発光する発光層１４３を有する領域、及び青色の光を発光する発光層１４３を有する領域が繰り返し設けられていても良い。この場合、各領域を同時に発光させると、発光装置は白色等の単一の発光色で発光する。また、赤色、緑色、青色の各領域の光量のバランスを調節する制御を行うことにより、様々な光スペクトルでの発光を行うことができるようになっていても良い。 The light emitting layer 143 is, for example, a layer that emits red light, a layer that emits blue light, a layer that emits yellow light, or a layer that emits green light. In this case, in a plan view, a region having a light emitting layer 143 that emits red light, a region having a light emitting layer 143 that emits green light, and a region having a light emitting layer 143 that emits blue light are repeatedly provided.

Further, it may be possible to emit light in various light spectra by performing control for adjusting the balance of the light amounts of the red, green, and blue regions.
　なお、発光層１４３は、複数の色を発光するための材料を混ぜることにより、白色等の単一の発光色で発光するように構成されていても良い。 Note that the light emitting layer 143 may be configured to emit light in a single light emission color such as white by mixing materials for emitting a plurality of colors.
　図６は有機機能層１４０の層構造の第２例を示す断面図である。この有機機能層１４０の発光層１４３は、発光層１４３ａ、１４３ｂ、１４３ｃをこの順に積層した構成を有している。発光層１４３ａ、１４３ｂ、１４３ｃは、互いに異なる色の光（例えば赤、緑、及び青）を発光する。そして発光層１４３ａ、１４３ｂ、１４３ｃが同時に発光することにより、発光装置は白色等の単一の発光色で発光する。また、赤色、緑色、青色の各発光層１４３ａ、１４３ｂ、１４３ｃの光量のバランスを調節する制御を行うことにより、様々な光スペクトルでの発光を行うことができる。 FIG. 6 is a cross-sectional view showing a second example of the layer structure of the organic functional layer 140. The light emitting layer 143 of the organic functional layer 140 has a structure in which light emitting layers 143a, 143b, and 143c are stacked in this order. The light emitting layers 143a, 143b, and 143c emit light of different colors (for example, red, green, and blue). The light emitting layers 143a, 143b, and 143c emit light at the same time, so that the light emitting device emits light in a single emission color such as white. Further, by performing control for adjusting the balance of the light amounts of the red, green, and blue light emitting layers 143a, 143b, and 143c, light emission in various light spectra can be performed.

In other words, the inner cross-sectional area of the recess 41 decreases toward the depth direction of the recess 41. The fixed plate 3 has a terminal 411 exposed in the recess 41.
　また、凸部５１は、下方に向けて縮径している。すなわち、凸部５１の断面積は、凸部５１の先端に向けて小さくなっている。より具体的には、凸部５１は、基端側（上側）の弾性部５１２と、先端側（下側）の端子５１１と、を備えて構成されている。弾性部５１２は、例えば金属製のコイルスプリング等の導電性の弾性体からなる。端子５１１は、金属等の導電体からなる。弾性部５１２と端子５１１とは、互いに別体に形成された後で相互に接合されていても良いし、互いに一体成形されていても良い。端子５１１は、下方に向けて縮径している。弾性部５１２は、端子５１１に対して電気的に接続されているとともに、天板１１と端子５１１とを相互に機械的に連結している。 Moreover, the convex part 51 is diameter-reduced toward the downward direction. That is, the cross-sectional area of the convex portion 51 decreases toward the tip of the convex portion 51. More specifically, the convex portion 51 includes a proximal end (upper) elastic portion 512 and a distal end (lower) terminal 511. The elastic portion 512 is made of a conductive elastic body such as a metal coil spring. The terminal 511 is made of a conductor such as metal. The elastic portion 512 and the terminal 511 may be formed separately from each other and then joined to each other, or may be integrally formed with each other. The terminal 511 is reduced in diameter toward the lower side. The elastic portion 512 is electrically connected to the terminal 511 and mechanically connects the top plate 11 and the terminal 511 to each other.
　固定板３は、上記実施形態と同様に３つの凹部４１を有している。このうち第１の凹部４１内の端子４１１は、固定板３内に形成された第１の導線（図示略）を介して、発光素子２の第１電極１３０に対して電気的に接続されている。また、第２の凹部４１内の端子４１１は、固定板３内に形成された第２の導線（図示略）を介して、発光素子２の第２電極１５０に対して電気的に接続されている。また、第３の凹部４１内の端子４１１は、固定板３内に形成された第３の導線（図示略）を介して、制御部６に対して電気的に接続されている。 The fixing plate 3 has three concave portions 41 as in the above embodiment. Among these, the terminal 411 in the first recess 41 is electrically connected to the first electrode 130 of the light emitting element 2 via a first conductive wire (not shown) formed in the fixed plate 3.

In addition, the terminal 411 in the second recess 41 is electrically connected to the second electrode 150 of the light emitting element 2 via a second conductive wire (not shown) formed in the fixed plate 3. Yes. Further, the terminal 411 in the third recess 41 is electrically connected to the control unit 6 via a third conducting wire (not shown) formed in the fixed plate 3.
　また、取付ベース部材１は、上記実施形態と同様に３つの凸部５１を有している。そして、このうち第１の凸部５１の端子５１１と対応する弾性部５１２と、第２の凸部５１の端子５１１と対応する弾性部５１２とは、天板１１内に形成された第４の導線および第５の導線（何れも図示略）をそれぞれ介して、図示しない電源に接続されている。また、第３の凸部５１の端子５１１と対応する弾性部５１２は、天板１１内に形成された第６の導線（図示略）を介して、例えば図示しない操作部に接続されている。 Further, the mounting base member 1 has three convex portions 51 as in the above embodiment. Of these, the elastic portion 512 corresponding to the terminal 511 of the first convex portion 51 and the elastic portion 512 corresponding to the terminal 511 of the second convex portion 51 are the fourth formed in the top plate 11. It is connected to a power source (not shown) via a conducting wire and a fifth conducting wire (both not shown).

At this time, since the elastic portion 512 serves as a cushion, the impact at the time of contact between each convex portion 51 and each concave portion 41 is alleviated.
　また、このように各凸部５１が各凹部４１に嵌入することにより、各凸部５１の端子５１１と各凹部４１の端子４１１とが相互に接触するとともに相互に電気的に接続される。電源からの電力は、第１の凹部４１の端子４１１と第２の凹部４１の端子４１１を介して、それぞれ第１電極１３０および第２電極１５０へ供給される。このように、本実施例の場合、凹部４１には、発光素子２に電力を供給するための端子４１１が設けられている。また、操作部に対する操作により生成された信号（例えば、発光素子２の発光をオン／オフするための信号等）は、第３の凹部４１の端子４１１を介して、制御部６に供給される。制御部６は、この信号に基づいて、発光素子２の発光を制御する。このように、本実施例の場合、凹部４１には、制御部６へ制御に関する信号を供給するための端子４１１が設けられている。 In addition, by inserting the convex portions 51 into the concave portions 41 in this way, the terminals 511 of the convex portions 51 and the terminals 411 of the concave portions 41 are in contact with each other and electrically connected to each other. Power from the power source is supplied to the first electrode 130 and the second electrode 150 via the terminal 411 of the first recess 41 and the terminal 411 of the second recess 41, respectively. As described above, in this embodiment, the recess 41 is provided with the terminal 411 for supplying power to the light emitting element 2. In addition, a signal generated by an operation on the operation unit (for example, a signal for turning on / off the light emission of the light emitting element 2) is supplied to the control unit 6 via the terminal 411 of the third recess 41. . The controller 6 controls the light emission of the light emitting element 2 based on this signal. Thus, in the case of the present embodiment, the recess 41 is provided with the terminal 411 for supplying a signal related to control to the control unit 6.

　凹凸構造４は、少なくとも凹部４１を含み、凹部４１の内空断面積は、凹部４１の深さ方向に向けて小さくなっているので、凹部４１内にスムーズに凸部５１を案内することができる。 The concavo-convex structure 4 includes at least a concave portion 41, and since the inner cross-sectional area of the concave portion 41 becomes smaller in the depth direction of the concave portion 41, the convex portion 51 can be smoothly guided into the concave portion 41. .
　また、凹部４１には、発光素子２に電力を供給するための端子４１１が設けられているので、端子４１１から発光素子２へ電力を供給することができる。 Further, since the recess 41 is provided with a terminal 411 for supplying power to the light emitting element 2, power can be supplied from the terminal 411 to the light emitting element 2.
　また、凹部４１には、制御部６へ制御に関する信号を供給するための端子４１１が設けられているので、端子４１１から制御部６へ制御に関する信号を供給することができる。 Further, since the recess 41 is provided with a terminal 411 for supplying a signal related to control to the control unit 6, a signal related to control can be supplied from the terminal 411 to the control unit 6.
　なお、本実施例では、固定板３に凹部４１を形成し、取付ベース部材１に凸部５１を設ける例を説明したが、固定板３に凸部を形成し、この凸部が嵌入する凹部を取付ベース部材１に設けても良い。この場合に、固定板３の凸部の断面積は、該凸部の基端に向けて大きくなっていても良い。このようにすることにより、取付ベース部材１の凹部内にスムーズに凸部を案内することができる。 In the present embodiment, an example in which the concave portion 41 is formed in the fixing plate 3 and the convex portion 51 is provided in the mounting base member 1 has been described. However, the concave portion in which the convex portion is formed in the fixing plate 3 and this convex portion is fitted. May be provided on the mounting base member 1. In this case, the cross-sectional area of the convex portion of the fixing plate 3 may increase toward the base end of the convex portion. By doing in this way, a convex part can be smoothly guided in the recessed part of the attachment base member 1. FIG.
