　従来から、例えばスイッチユニットの意匠面を裏面から照明する照明装置が知られている（特許文献１参照）。 Conventionally, for example, a lighting device is known which illuminates a design surface of a switch unit from the back side (see Patent Document 1).
　かかる照明装置は、小型ランプと、この小型ランプを装着するソケットとを有し、ソケットは小型ランプの電極に接続されるコンタクト部を有しており、ソケットをプリント基板の取付孔に取り付けると、ソケットのコンタクト部がプリント基板に設けた円弧状パターン面に接触し、これにより小型ランプが点灯し、スイッチユニットの意匠面を裏面から照明するようになっている。 Such a lighting device has a small lamp and a socket for mounting the small lamp, and the socket has a contact portion connected to the electrode of the small lamp, and the socket is mounted in the mounting hole of the printed circuit board The contact portion of the socket comes in contact with the arc-shaped pattern surface provided on the printed circuit board, whereby the small lamp is turned on to illuminate the design surface of the switch unit from the back surface.

発明が解決しようとうする課題Problems that the Invention is to Solve
ところで、近年、小型ランプの替わりに発光ダイオードが使用されることが提案されており、発光ダイオードは個々の特性のバラツキにより、所定の電圧を印加しても明るさがそれぞれ異なる。このため、特性のバラツキに拘わらず明るさを一定にするためには、それぞれの発光ダイオードに応じた抵抗値の抵抗体を直列接続して、その明るさが一定となるようにしている。
抵抗体は発光ダイオードを取り付ける回路基板にハンダ付けにより取り付けているが、そのハンダ付け作業が面倒であり、手間がかかるという問題がある。 In recent years, it has been proposed that a light emitting diode is used instead of a small lamp, and the brightness of the light emitting diode is different even when a predetermined voltage is applied due to the variation of individual characteristics. Therefore, in order to make the brightness constant regardless of the variation in characteristics, resistors of resistance values corresponding to the respective light emitting diodes are connected in series to make the brightness constant.
The resistor is attached to the circuit board to which the light emitting diode is attached by soldering, but the soldering operation is troublesome and there is a problem that it takes time and effort.
　この発明の目的は、抵抗体をハンダ付けする必要のない照明装置を提供することにある。 An object of the present invention is to provide a lighting device which does not need to solder a resistor.

[Light emitting diode]
As shown in FIGS. 8 and 13, the light emitting diode 70 has terminals 71 and 72 at the lower part, and has a light emitting part 73 on the upper surface. The terminal 71 is connected to the anode of the light emitting diode, the terminal 72 is connected to the cathode, and when a positive voltage is applied to the terminal 71 and a negative voltage is applied to the terminal 72, a current flows through the light emitting diode 70. The light emitting unit 73 emits light. The light emitted by the light emitting unit 73 is emitted upward.
[Cap lens]
The cap lens 50 is formed of a transparent resin, and has a cylindrical cap portion 51 and a lens portion 60 integrally formed on the upper surface of the cap portion 51 as shown in FIGS.
[Cap section]
The cap portion 51 includes a cylindrical portion 52, leg portions 53 and 54 protruding downward from the lower surface of the cylindrical portion 52 and opposed in the front-rear direction (left and right direction in FIG. 18), and lower portions from the lower surface of the cylindrical portion 52. It has the contact walls 55 and 56 which were protruded and mutually opposed in the left-right direction.
　脚部５３,５４は、図８及び図９に示すようにソケット２０の突出壁２３,２４の凹部２３Ａ,２４Ａに挿入されるようになっている。脚部５３,５４の下部には、穴５３Ａ,５４Ａが形成され、この穴５３Ａ,５４Ａには、ソケット２０の突出壁２３,２４の凹部２３Ａ,２４Ａの突起２５,２６が係合するようになっている。脚部５３,５４は、ソケット２０に対するキャップレンズ５０の前後方向の位置決めを行うようになっている。 The legs 53 and 54 are inserted into the recesses 23A and 24A of the projecting walls 23 and 24 of the socket 20 as shown in FIGS. Holes 53A and 54A are formed in lower parts of the legs 53 and 54, and the projections 25 and 26 of the recesses 23A and 24A of the projecting walls 23 and 24 of the socket 20 engage with the holes 53A and 54A. It has become. The legs 53 and 54 are adapted to position the cap lens 50 in the front-rear direction with respect to the socket 20.
　当接壁５５,５６は、ソケット２０の支持片２７,２８を外側から挟み込む位置に配置され、ソケット２０の支持片２７,２８の外面に当接して、ソケット２０に対するキャップレンズ５０の左右方向の位置決めを行うようになっている。 The contact walls 55 and 56 are disposed at positions sandwiching the support pieces 27 and 28 of the socket 20 from the outside, and abut on the outer surfaces of the support pieces 27 and 28 of the socket 20. It is designed to perform positioning.
  当接壁５６の一端には、下方に突出した突起５７が形成され、図９に示すように、この突起５７がソケット２０の円柱部２２の切欠２２Ｓ内に入るようになっている。この突起５７によって、円柱部２２の突出部３３と突出壁２３との間には切欠は設けられていないことにより、キャップレンズ５０はソケット２０に対して逆向き、すなわち、後述する射出面６２の向きが図８及び図９に示す向きと逆方向に向けられて、キャップレンズ５０がソケット２０に装着されないようになっている。 A projection 57 projecting downward is formed at one end of the abutting wall 56, and as shown in FIG. 9, the projection 57 is inserted into the notch 22S of the cylindrical portion 22 of the socket 20. The cap lens 50 is directed in the opposite direction to the socket 20 by the projection 57 and the notch is not provided between the projection 33 and the projection wall 23 of the cylindrical portion 22, that is, the projection surface 62 to be described later. The orientation is reversed from the orientation shown in FIGS. 8 and 9 so that the cap lens 50 is not attached to the socket 20.
　キャップ部５１の底面には、図１２Ａ及び図１６に示すように、発光ダイオード７０から発光した光が入射する入射面５１Ａを有している。
［レンズ部］
　レンズ部６０は、キャップ部５１の入射面５１Ａから入射してきた光を反射させる反射面である傾斜面６１と、傾斜面６１で反射した光を射出する射出面６２とを有している。 On the bottom surface of the cap portion 51, as shown in FIGS. 12A and 16, there is provided an incident surface 51A on which the light emitted from the light emitting diode 70 is incident.
[Lens section]
The lens unit 60 has an inclined surface 61, which is a reflection surface for reflecting light incident from the incident surface 51A of the cap unit 51, and an emission surface 62, which emits light reflected by the inclined surface 61.
　図５に示すように、傾斜面６１の傾斜方向をＹ軸（縦軸）に、Ｙ軸と直交する方向にＸ軸（横軸）を取った場合、傾斜面６１は、Ｘ－Ｙ平面に対して内側に凹むように湾曲面に形成され、Ｘ軸に対して一定の曲率で湾曲し、Ｙ軸に対して一定の曲率で湾曲し、これら曲率が異なっている。すなわち、レンズ部６０内から見た傾斜面６１は縦と横の曲率が異なる凸面鏡として機能する。 As shown in FIG. 5, when the inclined direction of the inclined surface 61 is taken as the Y axis (vertical axis) and the X axis (horizontal axis) is taken in the direction orthogonal to the Y axis, the inclined surface 61 is taken as the XY plane. On the other hand, it is formed in a curved surface so as to be recessed inward, is curved with a constant curvature with respect to the X axis, and is curved with a constant curvature with respect to the Y axis, and these curvatures are different. That is, the inclined surface 61 viewed from the inside of the lens unit 60 functions as a convex mirror having different vertical and horizontal curvatures.
　したがって、キャップ部５１の入射面５１Ａから入射してきた光は、傾斜面６１である凸面鏡で反射されて、左右方向と上下方向（図５において）とに広げられて射出面６２に到達する。 Therefore, light incident from the incident surface 51 A of the cap 51 is reflected by the convex mirror which is the inclined surface 61, and is spread in the lateral direction and the vertical direction (in FIG. 5) to reach the emission surface 62.
　射出面６２の中央部６２Ａは、図９に示すように、左右方向に沿った軸線（図示せず）を有する凹面状の円柱レンズ部となっている。中央部６２Ａの上下の両側である上下部６２Ｂ,６２Ｃが平面となっている。　 As shown in FIG. 9, the central portion 62A of the exit surface 62 is a concave cylindrical lens portion having an axis (not shown) along the left-right direction. Upper and lower portions 62B and 62C which are both upper and lower sides of the central portion 62A are flat.
  射出面６２の中央部６２Ａに到達する光は、その円柱レンズ部により上下方向に広げられて、中央部より弱い光が到達する上下部６２Ｂ,６２Ｃに配光されることになる。このため、上下方向に広げられて射出面６２から射出される光は上下方向に対してほぼ均一な明るさとなる。 The light reaching the central portion 62A of the emission surface 62 is spread in the vertical direction by the cylindrical lens portion, and is distributed to the upper and lower portions 62B and 62C to which light weaker than the central portion reaches. For this reason, the light which is spread in the vertical direction and emitted from the emission surface 62 has substantially uniform brightness in the vertical direction.
　この実施例では、傾斜面６１の縦の横の曲率が異なっているが、同一にした球面状に形成してもよい。
［組み付け］
　照明装置１０の組み付けは、先ず、抵抗体８０を図１１及び図１２に示すようにソケット２０の穴２９に入れる。なお、ソケット２０には端子板１００,１１０がインサート成型や折り曲げ加工により、図５ないし図１０に示すように既に配設されている。 In this embodiment, although the vertical and horizontal curvatures of the inclined surface 61 are different, they may be formed in the same spherical shape.
[Assembly]
In assembling the lighting device 10, first, the resistor 80 is inserted into the hole 29 of the socket 20 as shown in FIGS. The terminal boards 100 and 110 are already arranged in the socket 20 by insert molding or bending as shown in FIG. 5 to FIG.
　抵抗体８０が穴２９へ挿入されると、図１６に示すように抵抗体８０の端子８０Ｂが端子板１１０の端子１１３に接触する。 When the resistor 80 is inserted into the hole 29, the terminal 80B of the resistor 80 contacts the terminal 113 of the terminal plate 110 as shown in FIG.
　次に、端子板９０の固定片９２をソケット２０の孔３１に挿入して、端子板９０を図１２に示すように、抵抗体８０の上に取り付ける。これにより端子板９０の接触片９１が抵抗体８０の端子８０Ａに接触する。 Next, the fixing piece 92 of the terminal plate 90 is inserted into the hole 31 of the socket 20, and the terminal plate 90 is mounted on the resistor 80 as shown in FIG. As a result, the contact piece 91 of the terminal plate 90 contacts the terminal 80A of the resistor 80.
　この後、図９及び図１０に示すように、ソケット２０の支持片２７,２８間に発光ダイオード７０を上から挿入して取り付ける。発光ダイオード７０は、突出壁２３,２４と支持片２７,２８とによって前後・左右に位置決めされることになる。 Thereafter, as shown in FIG. 9 and FIG. 10, the light emitting diode 70 is inserted between the support pieces 27 and 28 of the socket 20 from above and attached. The light emitting diode 70 is positioned back and forth and right and left by the projecting walls 23 and 24 and the support pieces 27 and 28.
　この取り付けにより、発光ダイオード７０の端子７１が端子板９０の接点部９４に接触し、発光ダイオード７０の端子７２が端子板１００の接点部１０６に接触する。 By this attachment, the terminal 71 of the light emitting diode 70 contacts the contact portion 94 of the terminal plate 90, and the terminal 72 of the light emitting diode 70 contacts the contact portion 106 of the terminal plate 100.
　次に、キャップレンズ５０の脚部５３,５４をソケット２０の突出壁２３,２４の凹部２３Ａ,２４Ａ内に上から挿入していき、脚部５３,５４を図５及び図１１に示す位置まで突出壁２３,２４の凹部２３Ａ,２４Ａ内に入れていくと、脚部５３,５４の下部がソケット２０の凹部２３Ａ,２４Ａの突起２５,２６の傾斜面２５Ａ,２６Ａに案内されて突起２５,２６を乗り越え、脚部５３,５４の穴５３Ａ,５４Ａに突起２５,２６が係合する。これにより、キャップレンズ５０がソケット２０に装着されることになる。 Next, the legs 53 and 54 of the cap lens 50 are inserted from above into the recesses 23A and 24A of the projecting walls 23 and 24 of the socket 20, and the legs 53 and 54 are moved to the positions shown in FIGS. The lower portions of the leg portions 53 and 54 are guided by the inclined surfaces 25A and 26A of the protrusions 25 and 26 of the concave portions 23A and 24A of the socket 20 as they enter the concave portions 23A and 24A of the protruding walls 23 and 24. 26, and the projections 25, 26 engage with the holes 53A, 54A of the legs 53, 54, respectively. Thus, the cap lens 50 is attached to the socket 20.
　この装着の際に、キャップレンズ５０の突起５７がソケット２０の円柱部２２の切欠２２Ｓ内に入り、キャップレンズ５０のソケット２０への装着が可能となる。これにより、キャップレンズ５０がソケット２０に対して逆向きに装着されるのが防止されることになる。 At the time of this mounting, the projection 57 of the cap lens 50 enters the notch 22S of the cylindrical portion 22 of the socket 20, and the cap lens 50 can be mounted on the socket 20. As a result, the cap lens 50 is prevented from being attached to the socket 20 in the reverse direction.
  キャップレンズ５０のソケット２０への装着により、発光ダイオード７０はキャップレンズ５０とソケット２０とで挟持された状態となる。 By mounting the cap lens 50 on the socket 20, the light emitting diode 70 is held between the cap lens 50 and the socket 20.
　また、キャップレンズ５０がソケット２０へ装着されると、発光ダイオード７０の発光部７３の外側である外周部がキャップレンズ５０のキャップ部５１の下面によって下方へ押圧されるようになっている。これによって、端子板１００の折曲部１０４が弾性を有していることにより、発光ダイオード７０の端子７２と端子板１００の接点部１０６とが圧接し、発光ダイオード７０の端子７２と端子板１００の接点部１０６とが確実に電気的に接触することになる。 In addition, when the cap lens 50 is attached to the socket 20, the outer peripheral portion which is the outer side of the light emitting portion 73 of the light emitting diode 70 is pressed downward by the lower surface of the cap portion 51 of the cap lens 50. As a result, the bent portion 104 of the terminal plate 100 has elasticity so that the terminal 72 of the light emitting diode 70 and the contact portion 106 of the terminal plate 100 come into pressure contact, and the terminal 72 of the light emitting diode 70 and the terminal plate 100 Thus, the contact portion 106 reliably comes in electrical contact.
　キャップレンズ５０の装着により、このキャップレンズ５０とソケット２０の端子板１１０とで、抵抗体８０と端子板９０と発光ダイオード７０とを端子板９０の弾性力を利用して挟持することになる。すなわち、抵抗体８０を端子板１１０と発光ダイオード７０の端子７１とで端子板９０を介して挟持することになり、抵抗体８０をハンダ付けしなくてよいことになる。 By mounting the cap lens 50, the resistor 80, the terminal plate 90, and the light emitting diode 70 are held between the cap lens 50 and the terminal plate 110 of the socket 20 using the elastic force of the terminal plate 90. That is, the resistor 80 is held between the terminal plate 110 and the terminal 71 of the light emitting diode 70 via the terminal plate 90, and it is not necessary to solder the resistor 80.
　そして、端子板９０の折曲片９３が弾性を有していることにより、発光ダイオード７０の端子７１と端子板９０の接点部９４とが、抵抗体８０の端子８０Ａと端子板９０の接触片９１とが、抵抗体８０の端子８０Ｂと端子板１１０の端子１１３とが圧接し、それぞれが互いに確実に電気的に接触することになる。 Then, since the bent pieces 93 of the terminal plate 90 have elasticity, the terminals 71 of the light emitting diode 70 and the contact portions 94 of the terminal plate 90 are the contact pieces of the terminal 80A of the resistor 80 and the terminal plate 90. In the case 91, the terminal 80B of the resistor 80 and the terminal 113 of the terminal plate 110 are in pressure contact with each other, so that they are in electrical contact with each other reliably.
　また、端子板９０の折曲片９３の弾性力によって、発光ダイオード７０はキャップレンズ５０のキャップ部５１の下面に当接されるので、ソケット２０に対する上下方向の位置決めされる。
［照明装置１０の装着］
　組み付けが完了した照明装置１０は、図２に示すハウジング２の基板２Ａの装着穴５に装着する。 Further, since the light emitting diode 70 is in contact with the lower surface of the cap portion 51 of the cap lens 50 by the elastic force of the bent piece 93 of the terminal plate 90, the light emitting diode 70 is positioned in the vertical direction relative to the socket 20.
[Mounting of lighting device 10]
The lighting device 10 that has been assembled is mounted in the mounting hole 5 of the substrate 2A of the housing 2 shown in FIG.
　この装着は、照明装置１０のキャップレンズ５０を、図４に示す基板２Ａの外面２Ａａから装着穴５へ挿入して行う。この挿入の際、ソケット２０の突出部３３,３４を装着穴５の凹部７,６に入れていき、ソケット２０のフランジ２１の上面２１Ａを基板２Ａの外面２Ａａに当接させる。そして、照明装置１０を図４において時計回りに回動させる。 This mounting is performed by inserting the cap lens 50 of the lighting device 10 from the outer surface 2Aa of the substrate 2A shown in FIG. 4 into the mounting hole 5. At the time of this insertion, the protrusions 33 and 34 of the socket 20 are inserted into the recesses 7 and 6 of the mounting hole 5, and the upper surface 21A of the flange 21 of the socket 20 is brought into contact with the outer surface 2Aa of the substrate 2A. Then, the lighting device 10 is rotated clockwise in FIG.
　この回動により、ソケット２０の突出部３３の上辺部３３Ａとフランジ２１の上面２１Ａとの間の間隙Ｋ１（図５参照）に、基板２Ａの凹部７の縁部７Ａが入り込んでいく。同様に、ソケット２０の間隙Ｋ２（図９参照）に、基板２Ａの凹部６の縁部６Ａが入り込んでいく。 By this rotation, the edge 7A of the recess 7 of the substrate 2A enters the gap K1 (see FIG. 5) between the upper side 33A of the protrusion 33 of the socket 20 and the upper surface 21A of the flange 21. Similarly, the edge 6A of the recess 6 of the substrate 2A enters the gap K2 (see FIG. 9) of the socket 20.
　これにより、図２４に示すように、端子板１００,１１０の摺接部１０２,１１２が基板２Ａの電極パターン８,９上を摺接していく。 Thereby, as shown in FIG. 24, the sliding contact portions 102 and 112 of the terminal boards 100 and 110 slide on the electrode patterns 8 and 9 of the substrate 2A.
　基板２Ａの凹部６,７の縁部６Ａ,７Ａがソケット２０の突出部３３の支持部３３Ｂに当接するまで、照明装置１０を回動させれば照明装置１０の基板２Ａへの装着が完了する。 The mounting of the lighting device 10 on the substrate 2A is completed by rotating the lighting device 10 until the edges 6A, 7A of the recessed portions 6, 7 of the substrate 2A abut the supporting portions 33B of the projecting portion 33 of the socket 20 .
　基板２Ａの凹部６,７の縁部６Ａ,７Ａがソケット２０の突出部３３の支持部３３Ｂに当接すると、照明装置１０のキャップレンズ５０の射出面６２がスイッチ装置１の操作ボタン３の意匠面３Ａに向けられる（図１参照）。 When the edges 6A and 7A of the recessed portions 6 and 7 of the substrate 2A abut the supporting portion 33B of the projecting portion 33 of the socket 20, the emission surface 62 of the cap lens 50 of the lighting device 10 is a design of the operation button 3 of the switch device 1. It is directed to face 3A (see FIG. 1).
　このとき、端子板１００,１１０の摺接部１０２,１１２が基板２Ａの電極パターン９,８に接触しており、発光ダイオード７０の端子７２は端子板１００を介し電極パターン９に接触し（図１３参照）、発光ダイオード７０の端子７１は端子板９０と抵抗体８０と端子板１１０を介して電極パターン８に接触する。　 At this time, the sliding contact portions 102 and 112 of the terminal boards 100 and 110 are in contact with the electrode patterns 9 and 8 of the substrate 2A, and the terminals 72 of the light emitting diodes 70 are in contact with the electrode patterns 9 via the terminal board 100 (see FIG. 13), the terminal 71 of the light emitting diode 70 is in contact with the electrode pattern 8 through the terminal plate 90, the resistor 80 and the terminal plate 110.
　このため、直流電源から電極パターン９にプラスの電圧が、電極パターン８にマイナスの電圧が印加されると、発光ダイオード７０に電流が流れて発光ダイオード７０が発光する。 Therefore, when a positive voltage is applied to the electrode pattern 9 and a negative voltage is applied to the electrode pattern 8 from the DC power supply, a current flows through the light emitting diode 70, and the light emitting diode 70 emits light.
　発光ダイオード７０の発光部７３から発光した光Ｑ１,Ｑ２は、図１１に示すように、キャップレンズ５０のキャップ部５１の入射面５１Ａに入射し、光Ｑ１はレンズ部６０の傾斜面６１で反射して射出面６２の中央部６２Ａから射出され、光Ｑ２は射出面６２の下部６２Ｃから射出される。この射出面６２からは、傾斜面６１などにより、図５に示すように上下方向に角度αで、左右方向に角度βで広がるように射出されていく。 The lights Q1 and Q2 emitted from the light emitting portion 73 of the light emitting diode 70 are incident on the incident surface 51A of the cap portion 51 of the cap lens 50, and the light Q1 is reflected by the inclined surface 61 of the lens portion 60 as shown in FIG. Then, the light Q2 is emitted from the central portion 62A of the emission surface 62, and the light Q2 is emitted from the lower portion 62C of the emission surface 62. As shown in FIG. 5, the light is emitted from the emission surface 62 so as to spread at an angle α in the vertical direction and at an angle β in the horizontal direction as shown in FIG.
　このため、指向性のある発光ダイオード７０であっても、操作ボタン３の意匠面３Ａを裏面から広範囲に渡って照明することができる。しかも、射出面６２の中央部６２Ａが凹面状となっていることにより、中央部６２Ａに到達する強い光が上下方向に広げられるので、操作ボタン３の意匠面３Ａを裏面から広範囲に渡って均一に照明することができることになる。 Therefore, even with the directional light emitting diode 70, the design surface 3A of the operation button 3 can be widely illuminated from the back surface. Moreover, since the central portion 62A of the emission surface 62 is concave, the strong light reaching the central portion 62A can be spread in the vertical direction, so the design surface 3A of the operation button 3 is uniform over a wide area from the back surface. It will be possible to illuminate.
　以上説明したように、抵抗体８０は端子板１１０と発光ダイオード７０の端子７１とによって端子板９０の弾性力によって挟持されるので、抵抗体８０をハンダ付けする必要がなく、このため、照明装置１０の組み付け作業は簡単に行うことなできる。 As described above, since the resistor 80 is held between the terminal plate 110 and the terminal 71 of the light emitting diode 70 by the elastic force of the terminal plate 90, there is no need to solder the resistor 80. Therefore, the lighting device The 10 assembling operations can be easily performed.
　この実施例では、照明する意匠面３Ａと、照明装置１０を装着する基板２Ａの面とが直交する場合であっても、発光ダイオード７０で照明することができる。 In this embodiment, even when the design surface 3A to be illuminated and the surface of the substrate 2A on which the illumination device 10 is mounted are orthogonal to each other, the light emitting diode 70 can illuminate.
　しかも、ソケット２０に対するキャップレンズ５０の取り付けの向きや、ソケット２０の基板２Ａの装着穴５への装着の向きが決められているので、照明装置１０を基板２Ａの装着穴５に装着させるだけで、照明装置１０で操作ボタン３の意匠面３Ａを裏面から常に照明することができる。また、ソケット２０の基板２Ａの装着穴５への装着の向きが決められていることにより、発光ダイオード７０の端子７１,７２に逆向きの電圧を印加させてしまうことも防止することができる。 Moreover, since the mounting direction of the cap lens 50 with respect to the socket 20 and the mounting direction of the socket 20 to the mounting hole 5 of the substrate 2A are determined, only by mounting the lighting device 10 in the mounting hole 5 of the substrate 2A. The design surface 3A of the operation button 3 can always be illuminated from the back by the lighting device 10. In addition, by determining the mounting direction of the socket 20 in the mounting hole 5 of the substrate 2A, it is possible to prevent the reverse voltage from being applied to the terminals 71 and 72 of the light emitting diode 70.
　上記実施例では、ソケット２０の突出部３３,３４と、基板２Ａの装着穴５の凹部６,７とで、ソケット２０の装着向きを規制しているが、この逆にソケット２０に凹部を設け、基板２Ａの装着穴５に突出部を設けて規制してもよい。 In the above embodiment, the mounting direction of the socket 20 is regulated by the projecting portions 33 and 34 of the socket 20 and the concave portions 6 and 7 of the mounting hole 5 of the substrate 2A. A protrusion may be provided in the mounting hole 5 of the substrate 2A to regulate the same.

It may be a lens. Further, regardless of the shape of the inclined surface 61 of the lens unit 60, the exit surface 62 of the lens unit 60 may also be flat.
  また、キャップレンズ５０の射出面６２の中央部６２Ａおよび平面部６２Ｂ,６２Ｃが上下方向に設けられているが、射出面６２が９０度回転した状態に、すなわち、中央部６２Ａおよび平面部６２Ｂ,６２Ｃが左右方向に並ぶように設けてもよい。また、中央部６２Ａを円形にしてその周囲を平面にしてもよい。 Further, although the central portion 62A and the flat portions 62B and 62C of the exit surface 62 of the cap lens 50 are provided in the vertical direction, the central portion 62A and the flat portions 62B, 62C may be provided to be aligned in the left-right direction. In addition, the central portion 62A may be circular and its periphery may be flat.
　また、操作ボタン３の意匠面３Ａと基板２Ａの面とが直交しているが、必ずしも直交する必要はなく、意匠面３Ａと基板２Ａの面とのなす角度に合わせて、レンズ部６０の傾斜面６１の傾斜角度を設定すればよい。 Further, although the design surface 3A of the operation button 3 and the surface of the substrate 2A are orthogonal to each other, it does not necessarily have to be orthogonal, and the inclination of the lens portion 60 in accordance with the angle between the design surface 3A and the surface of the substrate 2A. The inclination angle of the surface 61 may be set.
　上記実施例では、キャップレンズ５０をソケット２０に装着した照明装置１０を基板２Ａの装着穴５に装着して、操作ボタン３の意匠面３Ａの裏面を発光ダイオード７０で照明するようにした照明装置について説明したが、単に、意匠面３Ａを裏面から発光ダイオード７０で照明する照明装置の場合は、ソケット２０は不要であり、この場合、発光ダイオード７０とキャップレンズ５０は基板２Ａに設けたものでもよい。 In the above embodiment, the illumination device 10 in which the cap lens 50 is attached to the socket 20 is attached to the attachment hole 5 of the substrate 2A, and the light emitting diode 70 illuminates the back surface of the design surface 3A of the operation button 3 However, in the case of a lighting device in which the design surface 3A is simply illuminated with the light emitting diode 70 from the back surface, the socket 20 is not necessary. In this case, even if the light emitting diode 70 and the cap lens 50 are provided on the substrate 2A. Good.
　上記実施例では、スイッチ装置１の操作ボタン３の意匠面３Ａを裏面から照明する照明装置１０について説明したが、スイッチ装置１の意匠面でなくてもよく、他の装置の意匠面を裏面から照明するものであってもよい。 In the above embodiment, although the lighting device 10 illuminates the design surface 3A of the operation button 3 of the switch device 1 from the back surface, the lighting device 10 does not have to be the design surface of the switch device 1. It may be illuminated.
