以下、本発明に係る発光装置について、好適な実施の形態を挙げ、添付の図面を参照しながら詳細に説明する。 Hereinafter, a light emitting device according to the present invention will be described in detail with reference to the accompanying drawings, with reference to preferred embodiments.

本実施の形態に係る発光装置１０は、車両室内の照明に用いられ、図１及び図２に示すように、光源としての発光素子１２と、前記発光素子１２が実装されて平面視で長方形状に形成された基板１４と、前記基板１４のうち前記発光素子１２が実装された面（以下、実装面と称することがある。）１６に装着されて前記発光素子１２に電気的に接続された電子部品１８と、前記基板１４に接続される一対の接続端子（ターミナル）２０ａ、２０ｂと、前記基板１４等が収容されるケース（支持部材）２２と、前記ケース２２に装着されるカバー部２４と、前記発光素子１２から発光された光を導く導光体２５とを備える。 The light emitting device 10 according to the present embodiment is used for illumination in a vehicle interior, and as shown in FIGS. 1 and 2, a light emitting element 12 serving as a light source, and a rectangular shape in plan view in which the light emitting element 12 is mounted. And a surface of the substrate 14 on which the light emitting element 12 is mounted (hereinafter, also referred to as a mounting surface) 16 and are electrically connected to the light emitting element 12. The electronic component 18, a pair of connection terminals (terminals) 20a and 20b connected to the board 14, a case (supporting member) 22 in which the board 14 and the like are housed, and a cover portion 24 attached to the case 22. And a light guide 25 that guides the light emitted from the light emitting element 12.

発光素子１２としては、例えば、ＬＥＤが用いられるが、有機ＥＬ等を用いることも可能である。このようなＬＥＤや有機ＥＬは、公知のものを利用することができる。発光素子１２は、基板１４の長手方向中央よりもやや一端部側に偏在している。 As the light emitting element 12, for example, an LED is used, but it is also possible to use an organic EL or the like. Known LEDs and organic ELs can be used. The light emitting element 12 is unevenly distributed on the one end side rather than the longitudinal center of the substrate 14.

電子部品１８は、発光素子１２への電源の供給制御等を行うためのものであって、抵抗器やダイオード等が例示される。前記電子部品１８は、基板１４の短手方向の略中央であって、長手方向中央よりもやや他端部側に偏在している。 The electronic component 18 is for controlling the supply of power to the light emitting element 12, and is exemplified by a resistor and a diode. The electronic component 18 is located substantially at the center in the lateral direction of the substrate 14 and slightly unevenly located on the other end side from the center in the longitudinal direction.

基板１４の長手方向に沿って電子部品１８よりも他端側に近接して一対の貫通孔２６ａ、２６ｂが形成されている。前記貫通孔２６ａ、２６ｂには前記接続端子２０ａ、２０ｂの一端部が挿入されるものであって、その離間間隔は、任意に設定可能である。この場合、これら貫通孔２６ａ、２６ｂに前記接続端子２０ａ、２０ｂを挿入して固定した状態で、該接続端子２０ａ、２０ｂ同士が接触しない程度の間隔が好ましい。なお、基板１４の裏面２８には、図示しないが、導体が面状、例えば、箔状に配設されており、発光素子１２、電子部品１８及び接続端子２０ａ、２０ｂは、前記導体を介して電気的に接続される。放熱効果を得るためである。 A pair of through holes 26a and 26b are formed along the longitudinal direction of the substrate 14 closer to the other end side than the electronic component 18. One ends of the connection terminals 20a and 20b are inserted into the through holes 26a and 26b, and the distance between them can be set arbitrarily. In this case, it is preferable that the connection terminals 20a and 20b are inserted and fixed in the through holes 26a and 26b, and the connection terminals 20a and 20b are not in contact with each other. Although not shown, conductors are arranged in a plane shape, for example, in a foil shape on the back surface 28 of the substrate 14, and the light emitting element 12, the electronic component 18, and the connection terminals 20a and 20b are connected via the conductor. It is electrically connected. This is to obtain a heat dissipation effect.

図２及び図８から諒解されるように、接続端子２０ａの両端面は、平坦に形成されている。但し、前記接続端子２０ａの両端部の形状は、特に限定されず、例えば、先細りのテーパ状に形成されていてもよい。この場合、接続端子２０ａの一端部を前記貫通孔２６ａに挿入し易くなると共に、接続端子２０ａの他端部を後述する電力供給用の外部コネクタに装着し易くなる。 As is clear from FIGS. 2 and 8, both end surfaces of the connection terminal 20a are formed flat. However, the shape of both ends of the connection terminal 20a is not particularly limited, and may be, for example, a tapered shape. In this case, one end of the connection terminal 20a can be easily inserted into the through hole 26a, and the other end of the connection terminal 20a can be easily attached to an external connector for power supply described later.

接続端子２０ａは、断面矩形状の細長い金属棒（金属板）で構成され、基板１４の貫通孔２６ａに挿入された状態で、基板１４に半田付けされる溶着部（図８参照）３０と、前記溶着部３０に連なる弧状の湾曲部３２と、前記湾曲部３２に連なり且つ他方の端部側に延伸するリード部３４とを有する。 The connection terminal 20a is composed of an elongated metal rod (metal plate) having a rectangular cross section, and a welding portion (see FIG. 8) 30 that is soldered to the substrate 14 in a state of being inserted into the through hole 26a of the substrate 14, The arc-shaped curved portion 32 is connected to the welded portion 30, and the lead portion 34 is connected to the curved portion 32 and extends to the other end side.

接続端子２０ａの厚みＴ１（図８参照）は、湾曲部３２を撓ませることが可能な程度の厚みに設定されている。これにより、湾曲部３２を撓ませて溶着部３０とリード部３４との位置関係を調整することが可能となる。実際、リード部３４は、図示しない電力供給用の外部コネクタに接続されるものであって、これにより、外部から発光素子１２に電力を供給することができる。なお、貫通孔２６ｂに挿入される接続端子２０ｂは、接続端子２０ａと同一構成であるため、その詳細な説明を省略する。 The thickness T1 (see FIG. 8) of the connection terminal 20a is set to a thickness that allows the bending portion 32 to bend. This makes it possible to bend the bending portion 32 and adjust the positional relationship between the welding portion 30 and the lead portion 34. In fact, the lead portion 34 is connected to an external connector for power supply (not shown), which allows power to be supplied to the light emitting element 12 from the outside. Since the connection terminal 20b inserted into the through hole 26b has the same configuration as the connection terminal 20a, detailed description thereof will be omitted.

図３に示すように、ケース２２は、幅広で一方向に延在し、基板１４が収容されるケース本体３６と、幅狭で前記ケース本体３６に接続されるコネクタ部３８とを有する。ケース本体３６とコネクタ部３８とは樹脂等で一体的に構成される。 As shown in FIG. 3, the case 22 includes a case body 36 that is wide and extends in one direction to accommodate the substrate 14, and a connector portion 38 that is narrow and connected to the case body 36. The case body 36 and the connector portion 38 are integrally formed of resin or the like.

図６を参照して、ケース本体３６は、平面視で略長方形状に形成された底部４０と、前記底部４０の短手方向の両端部に設けられた一対の第１段差部４２ａ、４２ｂと、前記一対の第１段差部４２ａ、４２ｂのそれぞれに連なる一対の第２段差部４４ａ、４４ｂと、前記一対の第２段差部４４ａ、４４ｂのそれぞれに連なる一対の側壁部４６ａ、４６ｂと、前記底部４０に立設されて該側壁部４６ａ、４６ｂの上端部近傍まで延在する壁部４８と、前記壁部４８に対向して前記底部４０に立設される分厚い壁部５０とを有する。 Referring to FIG. 6, the case main body 36 includes a bottom portion 40 formed in a substantially rectangular shape in a plan view, and a pair of first step portions 42a and 42b provided at both ends in the lateral direction of the bottom portion 40. A pair of second step portions 44a, 44b connected to each of the pair of first step portions 42a, 42b, and a pair of side wall portions 46a, 46b connected to each of the pair of second step portions 44a, 44b, It has a wall portion 48 standing on the bottom portion 40 and extending to the vicinity of the upper end portions of the side wall portions 46a, 46b, and a thick wall portion 50 facing the wall portion 48 and standing on the bottom portion 40.

第１段差部４２ａ、４２ｂは、側壁部４６ａ、４６ｂに沿って延びており、その一端部が壁部４８に接し、その他端部は壁部５０に接している。各第１段差部４２ａ、４２ｂは、底部４０の内面（基板１４との対向面）４０ａに連なる第１垂直面４３ａ、４３ｂと、前記第１垂直面４３ａ、４３ｂのそれぞれに連なる第１上面４５ａ、４５ｂを有する。 The first step portions 42a and 42b extend along the side wall portions 46a and 46b, one end of which is in contact with the wall portion 48, and the other end is in contact with the wall portion 50. Each of the first step portions 42a, 42b has a first vertical surface 43a, 43b continuous with the inner surface 40a of the bottom portion 40 (a surface facing the substrate 14) and a first upper surface 45a continuous with the first vertical surface 43a, 43b. , 45b.

第１垂直面４３ａ、４３ｂの幅（第１段差部４２ａ、４２ｂの高さ）Ｗ１は、基板１４の厚さＴ２と同程度の幅に設定されている。これにより、第１上面４５ａ、４５ｂに基板１４を載置した状態で、基板１４と底部４０の間に適度な隙間Ｓが形成されることとなる。これにより、発光素子１２及び電子部品１８から発生した熱を該隙間Ｓに拡散させることができるので、基板１４の裏面２８全体を底部４０に接触させる場合と比較して、発光素子１２及び電子部品１８の温度上昇を抑えることができる。 The width (height of the first step portions 42a, 42b) W1 of the first vertical surfaces 43a, 43b is set to be approximately the same as the thickness T2 of the substrate 14. As a result, an appropriate gap S is formed between the substrate 14 and the bottom portion 40 with the substrate 14 placed on the first upper surfaces 45a and 45b. As a result, the heat generated from the light emitting element 12 and the electronic component 18 can be diffused into the gap S, so that the light emitting element 12 and the electronic component 12 can be compared with the case where the entire back surface 28 of the substrate 14 is brought into contact with the bottom portion 40. The temperature rise of 18 can be suppressed.

第２段差部４４ａ、４４ｂは、側壁部４６ａ、４６ｂに沿って延びており、その一端部が壁部４８に接し、その他端部はコネクタ部３８に接している。各第２段差部４４ａ、４４ｂは、第１上面４５ａ、４５ｂのそれぞれに連なる第２垂直面４７ａ、４７ｂと、前記第２垂直面４７ａ、４７ｂのそれぞれに連なる第２上面４９ａ、４９ｂを有する。 The second step portions 44a and 44b extend along the side wall portions 46a and 46b, one end portion of which is in contact with the wall portion 48, and the other end portion thereof is in contact with the connector portion 38. Each of the second step portions 44a, 44b has a second vertical surface 47a, 47b connected to each of the first upper surfaces 45a, 45b and a second upper surface 49a, 49b connected to each of the second vertical surfaces 47a, 47b.

第２垂直面４７ａ、４７ｂの幅（第２段差部４４ａ、４４ｂの高さ）Ｗ２は、基板１４の厚さＴ２よりも大きく設定されている。これにより、第１上面４５ａ、４５ｂに基板１４を載置した状態で、第２上面４９ａ、４９ｂが基板１４の実装面１６よりも上方に位置することとなる。 The width (height of the second step portions 44a, 44b) W2 of the second vertical surfaces 47a, 47b is set to be larger than the thickness T2 of the substrate 14. As a result, the second upper surfaces 49a and 49b are located above the mounting surface 16 of the substrate 14 with the substrate 14 placed on the first upper surfaces 45a and 45b.

第２垂直面４７ａ、４７ｂ同士の間隔は、基板１４の短手方向の幅と略同一に設定されている。これにより、基板１４の短手方向の移動を制限することができる。 The interval between the second vertical surfaces 47a and 47b is set to be substantially the same as the width of the substrate 14 in the lateral direction. Thereby, the movement of the substrate 14 in the lateral direction can be restricted.

図２に示すように、側壁部４６ａには所定間隔離間した複数（図では２つ）の装着孔（第２係合部）５２ａ、５２ｂが形成され、同様に側壁部４６ｂにも装着孔（第２係合部）５２ｃ、５２ｄが形成されている。装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄは、四角形状に開口し、この構成は後述するカバー部２４の装着爪（第１係合部）７０ａ、７０ｂと、装着爪（第１係合部）７０ｃ、７０ｄのそれぞれの形状に対応する。 As shown in FIG. 2, a plurality of (two in the figure) mounting holes (second engaging portions) 52a and 52b are formed in the side wall portion 46a at predetermined intervals, and similarly, the side wall portion 46b is also mounted with mounting holes (second engaging portions). Second engaging portions) 52c and 52d are formed. The mounting holes 52a and 52b and the mounting holes 52c and 52d are opened in a quadrangular shape, and this configuration has mounting claws (first engaging parts) 70a and 70b and a mounting claw (first engaging part) of the cover part 24 described later. ) Corresponding to the respective shapes of 70c and 70d.

装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄは、側壁部４６ａ、４６ｂの中央よりもやや上方に位置している。これにより、カバー部２４をケース２２に装着する際に、装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄのそれぞれを側壁部４６ａ、４６ｂの中央よりも下方に位置する場合と比較して、装着爪７０ａ、７０ｂと装着爪７０ｃ、７０ｄにて外方に押される側壁部４６ａ、４６ｂの弾性変形量を小さくすることができるので、より小さい力で該カバー部２４を該ケース２２に装着することができる。 The mounting holes 52a, 52b and the mounting holes 52c, 52d are located slightly above the center of the side wall portions 46a, 46b. As a result, when the cover portion 24 is mounted on the case 22, the mounting holes 52a and 52b and the mounting holes 52c and 52d are located below the center of the side wall portions 46a and 46b, respectively. Since it is possible to reduce the amount of elastic deformation of the side walls 46a and 46b that are pushed outward by the 70a and 70b and the mounting claws 70c and 70d, it is possible to mount the cover portion 24 on the case 22 with a smaller force. it can.

また、側壁部４６ａの装着孔５２ａ、５２ｂは、ケース２２の長手方向において、側壁部４６ａの一端から装着孔５２ａまでの間隔、装着孔５２ａと装着孔５２ｂの間隔、及び、装着孔５２ｂから側壁部４６ａの他端までの間隔が等しくなるように配置されている。側壁部４６ｂの装着孔５２ｃは、装着孔５２ａに対向しており、側壁部４６ｂの装着孔５２ｄは、装着孔５２ｂに対向している。これにより、ケース２２の長手方向に装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄを偏って位置する場合と比較して、該カバー部２４をバランス良く保持することができる。 In addition, the mounting holes 52a and 52b of the side wall portion 46a are arranged such that, in the longitudinal direction of the case 22, the distance from one end of the side wall portion 46a to the mounting hole 52a, the distance between the mounting hole 52a and the mounting hole 52b, and the side wall from the mounting hole 52b. It is arranged so that the interval to the other end of the portion 46a is equal. The mounting hole 52c of the side wall portion 46b faces the mounting hole 52a, and the mounting hole 52d of the side wall portion 46b faces the mounting hole 52b. As a result, the cover portion 24 can be held in a well-balanced manner as compared with the case where the mounting holes 52a and 52b and the mounting holes 52c and 52d are located in a deviated position in the longitudinal direction of the case 22.

各側壁部４６ａ、４６ｂの外面には、装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄ間に位置し、且つ、車体パネルＰに設けられた後述の固定部２００ａ、２００ｂに係合する固定爪５４ａ、５４ｂがそれぞれ形成されている（図９参照）。各固定爪５４ａ、５４ｂは、ケース２２の長手方向に沿って延在し、略直方体形状に構成された基部５５ａ、５５ｂと一体的に形成され、且つ、上端部から外方に向かって下傾するテーパ部５７ａ、５７ｂを含む。 On the outer surface of each of the side wall portions 46a and 46b, a fixing claw 54a that is located between the mounting holes 52a and 52b and the mounting holes 52c and 52d and that engages with fixing portions 200a and 200b (described later) provided on the vehicle body panel P. , 54b are respectively formed (see FIG. 9). Each of the fixing claws 54a and 54b extends along the longitudinal direction of the case 22, is integrally formed with the bases 55a and 55b having a substantially rectangular parallelepiped shape, and is inclined downward from the upper end toward the outside.

An external connector for power supply (not shown) can be inserted into the inside of the cylinder. In the present embodiment, the vertical thickness of the connector portion 38 is formed larger than that of the case main body 36. A rectangular cutout portion 58 is formed in the wall portion 53 that constitutes the connector portion 38, and the width of the cutout portion 58 corresponds to the width of a cover extending portion 64 described later (see FIG. 2).

以上のように構成されたケース２２では、底部４０、第１段差部４２ａ、４２ｂ、第２段差部４４ａ、４４ｂ、側壁部４６ａ、４６ｂ、壁部４８、及び壁部５０で囲まれた空間とコネクタ部３８の切欠部５８とによって、カバー部２４が装着可能な空間（室）５９が形成されることとなる。 In the case 22 configured as described above, a space surrounded by the bottom portion 40, the first step portions 42a and 42b, the second step portions 44a and 44b, the side wall portions 46a and 46b, the wall portion 48, and the wall portion 50. The notch 58 of the connector 38 forms a space (chamber) 59 in which the cover 24 can be mounted.

図２及び図４に示すように、カバー部２４は、例えば、射出成形によって樹脂等で一体的に構成されており、平面視で略長方形状のカバー部本体６０と、前記カバー部本体６０の他端部から幅狭に延在するカバー延在部６４と、前記カバー部本体６０に形成されて導光体２５を内部に装着可能な筒部８０とを有する。 As shown in FIGS. 2 and 4, the cover part 24 is integrally formed of resin or the like by injection molding, for example, and has a substantially rectangular shape in plan view, and the cover part body 60. It has a cover extending portion 64 extending narrowly from the other end portion, and a tubular portion 80 formed in the cover portion main body 60 and capable of mounting the light guide 25 therein.

カバー部本体６０は、その外形形状を構成するベース部６１と、前記ベース部６１の短手方向両端部から長手方向に沿って下方に突出した一対の突出部６２ａ、６２ｂと、前記一対の突出部６２ａ、６２ｂに形成された一対の突起部６８ａ、６８ｂとを有する。 The cover portion main body 60 includes a base portion 61 that forms the outer shape thereof, a pair of protruding portions 62a and 62b that protrude downward from both ends in the lateral direction of the base portion 61 along the longitudinal direction, and the pair of protruding portions. It has a pair of protrusions 68a and 68b formed on the portions 62a and 62b.

前記突出部６２ａ、６２ｂの突出量は、上述した側壁部４６ａ、４６ｂの高さに対応して規定される。突起部６８ａ、６８ｂの長さは、突出部６２ａ、６２ｂの長さと同一に設定され、その突出量は、上述した第２垂直面４７ａ、４７ｂの幅Ｗ２と基板１４の厚さＴ２の差（Ｗ２−Ｔ２）と同程度に設定されている（図６参照）。 The amount of protrusion of the protrusions 62a and 62b is defined according to the height of the side wall portions 46a and 46b described above. The lengths of the protrusions 68a and 68b are set to be the same as the lengths of the protrusions 62a and 62b, and the protrusion amount is the difference between the width W2 of the second vertical surfaces 47a and 47b and the thickness T2 of the substrate 14 ( W2-T2) and is set to the same level (see FIG. 6).

各突出部６２ａ、６２ｂの外側面には、上述した装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄに嵌合可能な装着爪７０ａ、７０ｂと装着爪７０ｃ、７０ｄがそれぞれ互いに離間して設けられ、その離間間隔は、上述した装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄの離間間隔と同一に設定されている。装着爪７０ａ、７０ｂ、７０ｃ、７０ｄは、略直方体状であるが、その下端部は下方に向かうに従って徐々に先細りするテーパ状に形成されている。 Mounting claws 70a, 70b and mounting claws 70c, 70d that can be fitted into the above-described mounting holes 52a, 52b and mounting holes 52c, 52d are provided separately from each other on the outer surface of each of the projecting portions 62a, 62b, The spacing is set to be the same as the spacing between the mounting holes 52a and 52b and the mounting holes 52c and 52d described above. The mounting claws 70a, 70b, 70c, 70d have a substantially rectangular parallelepiped shape, but the lower end portion thereof is formed in a tapered shape that gradually tapers downward.

この場合、本実施の形態では、図６に示すように、突起部６８ａ、６８ｂの下端面６９ａ、６９ｂから装着爪７０ａ、７０ｂと装着爪７０ｃ、７０ｄの上端面までの距離Ｌ１は、ケース本体３６の第１上面４５ａ、４５ｂに基板１４を載置した状態において、基板１４の実装面１６から装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄの上端部までの距離Ｌ２よりも若干大きく設定されている。その理由については後述する。 In this case, in the present embodiment, as shown in FIG. 6, the distance L1 from the lower end surfaces 69a and 69b of the protrusions 68a and 68b to the upper ends of the mounting claws 70a and 70b and the mounting claws 70c and 70d is the case body. In a state where the board 14 is placed on the first upper surfaces 45a and 45b of 36, the distance L2 from the mounting surface 16 of the board 14 to the upper ends of the mounting holes 52a and 52b and the mounting holes 52c and 52d is set to be slightly larger than the distance L2. There is. The reason will be described later.

ベース部６１とカバー延在部６４の境界部には、下方に突出した端子保持部７２が形成されている（図４参照）。端子保持部７２の下端面７３と突起部６８ａ、６８ｂの下端面６９ａ、６９ｂとは、それぞれが一体に接続して平坦面を形成している。 A terminal holding portion 72 protruding downward is formed at a boundary portion between the base portion 61 and the cover extending portion 64 (see FIG. 4). The lower end surface 73 of the terminal holding portion 72 and the lower end surfaces 69a and 69b of the protrusions 68a and 68b are integrally connected to each other to form a flat surface.

端子保持部７２の下端面７３には、一対の凹部７４ａ、７４ｂがカバー部本体６０の短手方向に所定間隔離間して形成され、その離間間隔は、上述した壁部５０に設けられた配置溝５６ａ、５６ｂの離間間隔に対応している。 A pair of concave portions 74a and 74b are formed on the lower end surface 73 of the terminal holding portion 72 at a predetermined interval in the lateral direction of the cover body 60, and the distance between the recesses 74a and 74b is provided in the wall portion 50 described above. It corresponds to the spacing between the grooves 56a and 56b.

カバー延在部６４の下面のうち端子保持部７２に隣接する部位には、前記電力供給用の外部コネクタを保持するための溝７６が形成されている。 A groove 76 for holding the external connector for power supply is formed in a portion of the lower surface of the cover extending portion 64 adjacent to the terminal holding portion 72.

筒部８０は、略円筒状であってベース部６１の一端部側に位置しており、筒部８０の内部（内孔）は、ベース部６１の下端面に開口している。筒部８０には、その周方向に沿って４つの肉厚部位８２ａ、８２ｂ、８２ｃ、８２ｄが互いに離間して形成されている。なお、各肉厚部位８２ａ、８２ｂ、８２ｃ、８２ｄは、筒部８０の軸線方向全体に亘って延在しており、その筒部８０の周方向に沿った長さは略同一に設定されている。 The tubular portion 80 has a substantially cylindrical shape and is located on one end side of the base portion 61, and the inside (inner hole) of the tubular portion 80 is open to the lower end surface of the base portion 61. Four thick portions 82a, 82b, 82c, 82d are formed on the cylindrical portion 80 so as to be spaced from each other along the circumferential direction. Each of the thick portions 82a, 82b, 82c, 82d extends over the entire axial direction of the tubular portion 80, and the lengths of the tubular portion 80 along the circumferential direction are set to be substantially the same. There is.

肉厚部位８２ａと肉厚部位８２ｃは、ベース部６１の長手方向に沿って並んでおり、肉厚部位８２ｂと肉厚部位８２ｄは、ベース部６１の短手方向に沿って並んでいる。 The thick portion 82a and the thick portion 82c are arranged along the longitudinal direction of the base portion 61, and the thick portion 82b and the thick portion 82d are arranged along the lateral direction of the base portion 61.

図６に示すように、肉厚部位８２ｂの内周面の下端部には第１ストッパ部８６ａが形成され、肉厚部位８２ｄの内周面の下端部には前記第１ストッパ部８６ａに対向して第１ストッパ部８６ｂが形成されている。また、肉厚部位８２ｂの内周面の上端側には、筒部８０の軸線方向に延在して該筒部８０の上端面に開口した係止溝８８が形成されている。なお、係止溝８８は、筒部８０の上端面に開口していなくてもよい。つまり、係止溝８８の上端部は、筒部８０の上端面よりもやや下方に位置していても構わない。各第１ストッパ部８６ａ、８６ｂは、略直方体状に形成され、その上端面は平坦に形成されている。 As shown in FIG. 6, a first stopper portion 86a is formed at the lower end of the inner peripheral surface of the thick portion 82b, and a first stopper portion 86a is formed at the lower end of the inner peripheral surface of the thick portion 82d so as to face the first stopper portion 86a. Then, the first stopper portion 86b is formed. Further, on the upper end side of the inner peripheral surface of the thick portion 82b, a locking groove 88 is formed which extends in the axial direction of the tubular portion 80 and is open to the upper end surface of the tubular portion 80. The locking groove 88 does not have to be opened in the upper end surface of the tubular portion 80. That is, the upper end portion of the locking groove 88 may be located slightly below the upper end surface of the tubular portion 80. Each of the first stopper portions 86a and 86b is formed in a substantially rectangular parallelepiped shape, and the upper end surface thereof is formed flat.

図５に示すように、肉厚部位８２ａの内周面には、筒部８０の軸線方向に沿って延びた溝部９０ａが形成され、その溝部９０ａは、筒部８０の上端よりもやや下方の位置からその下端まで延在している。これにより、肉厚部位８２ａの内周面の上端部に後述する導光体２５の凸部９６ａが当接（係止）可能な第２ストッパ部９２ａが形成されることとなる。 As shown in FIG. 5, a groove portion 90a extending along the axial direction of the tubular portion 80 is formed on the inner peripheral surface of the thick portion 82a, and the groove portion 90a is located slightly below the upper end of the tubular portion 80. It extends from the position to its lower edge. As a result, the second stopper portion 92a is formed at the upper end of the inner peripheral surface of the thick portion 82a, with which the convex portion 96a of the light guide 25, which will be described later, can abut (lock).

肉厚部位８２ｃの内周面には、前記溝部９０ａと同一形状の溝部９０ｂが該溝部９０ａに対向して形成されている。これにより、肉厚部位８２ｃの内周面の上端部に後述する導光体２５の凸部９６ｂが当接（係止）可能な第２ストッパ部９２ｂが形成されることとなる。なお、第２ストッパ部９２ａ、９２ｂのそれぞれは、上端に向かうに従って先細りのテーパ状に形成され、その下端面は平坦に形成されている。 A groove portion 90b having the same shape as the groove portion 90a is formed on the inner peripheral surface of the thick portion 82c so as to face the groove portion 90a. As a result, the second stopper portion 92b with which the convex portion 96b of the light guide 25 described later can abut (lock) is formed at the upper end portion of the inner peripheral surface of the thick portion 82c. Each of the second stopper portions 92a and 92b is formed in a taper shape that tapers toward the upper end, and the lower end surface thereof is formed flat.

導光体２５は、透明体であって、樹脂材料で一体的に構成されている。また、図２、図５、及び、図６に示すように、導光体２５は、円柱状に形成された導光体本体９４と、前記導光体本体９４の外周面に形成されて上述した一対の溝部９０ａ、９０ｂのそれぞれに挿入可能な一対の凸部９６ａ、９６ｂと、前記導光体本体９４の外周面に形成されて該導光体本体９４の軸線方向に延びた略直方体状の係止用突起９８とを有する。 The light guide 25 is a transparent body and is integrally formed of a resin material. In addition, as shown in FIGS. 2, 5, and 6, the light guide 25 is formed on the light guide body 94 formed in a columnar shape, and on the outer peripheral surface of the light guide body 94. A pair of convex portions 96a and 96b that can be inserted into the pair of groove portions 90a and 90b, respectively, and a substantially rectangular parallelepiped shape that is formed on the outer peripheral surface of the light guide body 94 and extends in the axial direction of the light guide body 94. Locking projection 98.

導光体本体９４の外径は、筒部８０の内径に対応している。各凸部９６ａ、９６ｂは、略直方体状であるが、その下端部は下方に向かうに従って徐々に先細りするテーパ状に形成され、その上端面は平坦に形成されている。また、各凸部９６ａ、９６ｂは、溝部９０ａ、９０ｂに挿入可能な大きさに設定される。 The outer diameter of the light guide body 94 corresponds to the inner diameter of the tubular portion 80. Each of the convex portions 96a and 96b has a substantially rectangular parallelepiped shape, but the lower end portion thereof is formed in a taper shape that gradually tapers downward, and the upper end surface thereof is formed flat. Further, each of the convex portions 96a and 96b is set to a size that can be inserted into the groove portions 90a and 90b.

なお、導光体本体９４の下端面から凸部９６ａ、９６ｂの上端面までの距離Ｌ３は、第１ストッパ部８６ａ、８６ｂの上端面から第２ストッパ部９２ａ、９２ｂの下端面までの距離Ｌ４と略同一の長さに設定されている。この理由は後述する。 The distance L3 from the lower end surface of the light guide body 94 to the upper end surfaces of the convex portions 96a and 96b is the distance L4 from the upper end surfaces of the first stopper portions 86a and 86b to the lower end surfaces of the second stopper portions 92a and 92b. And the length is set to be almost the same. The reason for this will be described later.

係止用突起９８の幅（導光体本体９４の軸線方向及び半径方向に直交する方向に沿った長さ）は、上述した係止溝８８の溝幅と略同一に設定されている。これにより、係止用突起９８を係止溝８８に挿入した状態で、前記係止用突起９８が前記係止溝８８の一対の溝側面のそれぞれに接触するので、筒部８０の周方向において導光体２５を筒部８０に確実に位置決めすることができる。よって、筒部８０に対する導光体２５の誤組を防止することができる。また、導光体２５を筒部８０の内部に装着した状態で、該導光体２５が筒部８０の周方向に回転することを好適に防止することができる。 The width of the locking projection 98 (the length along the direction orthogonal to the axial direction and the radial direction of the light guide body 94) is set to be substantially the same as the groove width of the locking groove 88 described above. As a result, in a state where the locking projection 98 is inserted into the locking groove 88, the locking projection 98 comes into contact with each of the pair of groove side surfaces of the locking groove 88, so that in the circumferential direction of the tubular portion 80. The light guide 25 can be reliably positioned in the tubular portion 80. Therefore, it is possible to prevent erroneous assembly of the light guide 25 with respect to the tubular portion 80. Further, it is possible to preferably prevent the light guide 25 from rotating in the circumferential direction of the cylinder 80 in a state where the light guide 25 is mounted inside the cylinder 80.

次に、本実施形態に係る発光装置１０を組み立てる手順について説明する。先ず、基板１４の一方の面（実装面１６）に発光素子１２と電子部品１８をそれぞれ実装すると共に、基板１４の貫通孔２６ａ、２６ｂに接続端子２０ａ、２０ｂのそれぞれの溶着部３０を挿入し、該溶着部３０を半田付けにより基板１４に固定する。 Next, a procedure for assembling the light emitting device 10 according to the present embodiment will be described. First, the light emitting element 12 and the electronic component 18 are mounted on one surface (mounting surface 16) of the board 14, and the welding portions 30 of the connection terminals 20a and 20b are inserted into the through holes 26a and 26b of the board 14, respectively. The welded portion 30 is fixed to the substrate 14 by soldering.

その後、前記発光素子１２等が実装された基板１４をケース２２内に進入させる。このとき、図６に示すように、基板１４の裏面２８が第１上面４５ａ、４５ｂに接触すると共に、基板１４の側面が第２垂直面４７ａ、４７ｂに接触し、壁部５０の配置溝５６ａ、５６ｂ内に接続端子２０ａ、２０ｂのそれぞれのリード部３４が収納されることとなる。これにより、基板１４と接続端子２０ａ、２０ｂがケース２２内に位置決めされる。 After that, the substrate 14 on which the light emitting device 12 and the like are mounted is inserted into the case 22. At this time, as shown in FIG. 6, the back surface 28 of the substrate 14 contacts the first upper surfaces 45a and 45b, the side surface of the substrate 14 contacts the second vertical surfaces 47a and 47b, and the arrangement groove 56a of the wall portion 50 is formed. , 56b, the lead portions 34 of the connection terminals 20a, 20b are housed. As a result, the board 14 and the connection terminals 20a and 20b are positioned in the case 22.

また、導光体２５を筒部８０の内部に装着する。具体的には、図５に示すように、係止用突起９８が係止溝８８に挿入されるようにカバー部２４に対する導光体２５の向きを調節した上で、該導光体２５を筒部８０の内部に進入させる。そうすると、導光体本体９４の外周面と筒部８０の内周面とが接触した状態で、凸部９６ａ、９６ｂのテーパ面が第２ストッパ部９２ａ、９２ｂのテーパ面に接触するに至る。 Further, the light guide 25 is mounted inside the tubular portion 80. Specifically, as shown in FIG. 5, after adjusting the direction of the light guide 25 with respect to the cover portion 24 so that the locking projection 98 is inserted into the locking groove 88, the light guide 25 is fixed. It is made to enter the inside of the tubular portion 80. Then, in a state where the outer peripheral surface of the light guide body 94 and the inner peripheral surface of the tubular portion 80 are in contact with each other, the tapered surfaces of the convex portions 96a and 96b come into contact with the tapered surfaces of the second stopper portions 92a and 92b.

続いて、導光体２５をベース部６１が位置する側に押圧すると、肉厚部位８２ａ、８２ｃが互いに離間する方向（筒部８０の半径方向外方）に弾性変形しながら導光体２５が筒部８０の内部にさらに進入し、導光体本体９４の下端面が第１ストッパ部８６ａ、８６ｂの上端面に当接することとなる。このとき、弾性変形していた肉厚部位８２ａ、８２ｃは原形に復帰し、係止用突起９８は係止溝８８に配置され、凸部９６ａ、９６ｂは溝部９０ａ、９０ｂに配置される。 Subsequently, when the light guide 25 is pressed toward the side where the base portion 61 is located, the light guide 25 is elastically deformed in a direction in which the thick portions 82a and 82c are separated from each other (outward in the radial direction of the tubular portion 80). Further, the lower end surface of the light guide main body 94 comes into contact with the upper end surfaces of the first stopper portions 86a and 86b by further entering the inside of the tubular portion 80. At this time, the elastically deformed thick portions 82a and 82c return to the original shape, the locking projection 98 is arranged in the locking groove 88, and the convex portions 96a and 96b are arranged in the groove portions 90a and 90b.

なお、上述したように、導光体本体９４の下端面から凸部９６ａ、９６ｂの上端面までの距離Ｌ３が第１ストッパ部８６ａ、８６ｂの上端面から第２ストッパ部９２ａ、９２ｂの下端面までの距離Ｌ４と略同一に設定されているので、この状態において、凸部９６ａの上端面が第２ストッパ部９２ａの下端面に当接すると共に凸部９６ｂの上端面が第２ストッパ部９２ｂの下端面に当接する。その結果、導光体２５は、筒部８０の内部に位置決め保持される（図６参照）。なお、このとき、導光体本体９４の一部は、筒部８０から突出している。 Note that, as described above, the distance L3 from the lower end surface of the light guide body 94 to the upper end surfaces of the protrusions 96a and 96b is determined from the upper end surfaces of the first stopper portions 86a and 86b to the lower end surfaces of the second stopper portions 92a and 92b. Since it is set to be substantially the same as the distance L4 up to, the upper end surface of the convex portion 96a contacts the lower end surface of the second stopper portion 92a and the upper end surface of the convex portion 96b corresponds to the second stopper portion 92b in this state. Abut on the lower end surface. As a result, the light guide 25 is positioned and held inside the tubular portion 80 (see FIG. 6). At this time, a part of the light guide body 94 projects from the tubular portion 80.

続いて、カバー部２４をケース２２に装着する。具体的には、カバー部２４をケース２２に近接すると、カバー部２４の突出部６２ａ、６２ｂの外側面とケース本体３６の側壁部４６ａ、４６ｂの内面とが互いに接触した状態で突出部６２ａ、６２ｂの下端がケース本体３６内に進入し、このため装着爪７０ａ、７０ｂと、装着爪７０ｃ、７０ｄが側壁部４６ａ、４６ｂに接触するに至る。 Then, the cover portion 24 is attached to the case 22. Specifically, when the cover portion 24 approaches the case 22, the protruding portions 62a and 62b of the cover portion 24 and the inner surfaces of the side wall portions 46a and 46b of the case main body 36 are in contact with each other and the protruding portion 62a, The lower end of 62b enters the case main body 36, so that the mounting claws 70a, 70b and the mounting claws 70c, 70d come into contact with the side wall portions 46a, 46b.

そして、カバー部２４をケース本体３６の底部４０側に押圧すると、側壁部４６ａ、４６ｂが互いに離間する方向に弾性変形すると共に、その反力で突出部６２ａ、６２ｂが互いに近接する方向に弾性変形しながら、突出部６２ａ、６２ｂがケース本体３６内にさらに進入する。 When the cover portion 24 is pressed toward the bottom portion 40 of the case main body 36, the side walls 46a and 46b are elastically deformed in the direction of separating from each other, and the reaction force elastically deforms the protrusions 62a and 62b in the direction of approaching each other. Meanwhile, the protrusions 62a and 62b further enter into the case body 36.

その後、突起部６８ａ、６８ｂの下端面６９ａ、６９ｂが基板１４の実装面１６に接触すると共に、突出部６２ａ、６２ｂの下端面が第２上面４９ａ、４９ｂに接触することとなる。なお、上述したように、下端面６９ａ、６９ｂから装着爪７０ａ、７０ｂと装着爪７０ｃ、７０ｄの上端面までの距離Ｌ１が実装面１６から装着孔５２ａ、５２ｂ、と装着孔５２ｃ、５２ｄの上端部までの距離Ｌ２よりも大きく設定されているため、この状態において、装着爪７０ａ、７０ｂ、７０ｃ、７０ｄは未だ装着孔５２ａ、５２ｂ、５２ｃ、５２ｄに嵌合していない。 Then, the lower end surfaces 69a and 69b of the protrusions 68a and 68b contact the mounting surface 16 of the substrate 14, and the lower end surfaces of the protrusions 62a and 62b contact the second upper surfaces 49a and 49b. As described above, the distance L1 from the lower end surfaces 69a, 69b to the upper ends of the mounting claws 70a, 70b and the mounting claws 70c, 70d is determined by the mounting surface 16 to the upper ends of the mounting holes 52a, 52b and the mounting holes 52c, 52d. Since it is set to be larger than the distance L2 to the portion, in this state, the mounting claws 70a, 70b, 70c, 70d are not yet fitted in the mounting holes 52a, 52b, 52c, 52d.

次いで、カバー部２４を底部４０側にさらに押し込むと、ケース本体３６及びカバー部２４が若干撓むので、カバー部２４がケース本体３６内にさらに進入し、装着爪７０ａ、７０ｂ、７０ｃ、７０ｄが装着孔５２ａ、５２ｂ、５２ｃ、５２ｄに嵌合することとなる（図６参照）。このとき、弾性変形していた突出部６２ａ、６２ｂ及び側壁部４６ａ、４６ｂは原形に復帰する。その結果、カバー部２４は、突起部６８ａ、６８ｂの下端面６９ａ、６９ｂで基板１４の実装面１６を押圧した（実装面１６に当接した）状態でケース２２に装着される。このとき、端子保持部７２の下端面７３は、接続端子２０ａ、２０ｂのそれぞれのリード部３４に当接することとなる（図８参照）。 Then, when the cover portion 24 is further pushed into the bottom portion 40 side, the case body 36 and the cover portion 24 are slightly bent, so that the cover portion 24 further enters the case body 36 and the mounting claws 70a, 70b, 70c, 70d are removed. It will be fitted in the mounting holes 52a, 52b, 52c, 52d (see FIG. 6). At this time, the elastically deformed protrusions 62a and 62b and the side wall portions 46a and 46b are restored to their original shapes. As a result, the cover portion 24 is attached to the case 22 in a state in which the mounting surface 16 of the substrate 14 is pressed (contacted with the mounting surface 16) by the lower end surfaces 69a and 69b of the protrusions 68a and 68b. At this time, the lower end surface 73 of the terminal holding portion 72 comes into contact with the respective lead portions 34 of the connection terminals 20a and 20b (see FIG. 8).

以上のようにして組み立てられた発光装置１０は、図９に示すように、図示しない車両の車体パネルＰの所定の位置に配設される。具体的には、筒部８０における基板１４が位置する側とは反対側の開口部が鉛直下方に指向すると共に、車体パネルＰに形成された窓部Ｈと導光体本体９４とが対向するように車体パネルＰの裏面側（図９の二点鎖線の位置）に発光装置１０をセットし、該発光装置１０を車体パネルＰに接近させる。これにより、先ず、車体パネルＰの裏面側に設けられた樹脂製の固定部２００ａ、２００ｂが発光装置１０の固定爪５４ａ、５４ｂのテーパ部５７ａ、５７ｂに接触する。 The light emitting device 10 assembled as described above is arranged at a predetermined position of a vehicle body panel P of a vehicle (not shown) as shown in FIG. Specifically, the opening of the tubular portion 80 on the side opposite to the side on which the substrate 14 is located is directed vertically downward, and the window H formed in the vehicle body panel P and the light guide body 94 face each other. As described above, the light emitting device 10 is set on the back surface side of the vehicle body panel P (the position of the chain double-dashed line in FIG. 9), and the light emitting device 10 is brought close to the vehicle body panel P. As a result, first, the resin-made fixing portions 200a and 200b provided on the back surface side of the vehicle body panel P come into contact with the tapered portions 57a and 57b of the fixing claws 54a and 54b of the light emitting device 10.

次いで、発光装置１０をさらに車体パネルＰ側に押圧すると、固定部２００ａ、２００ｂが互いに離間する方向に弾性変形しながら、発光装置１０が車体パネルＰ側に進行し、筒部８０が車体パネルＰの裏面に当接すると共に導光体本体９４の一部が窓部Ｈに嵌まり込むと共に車両室内に露出する。このとき、弾性変形していた固定部２００ａ、２００ｂは原形に復帰する。その結果、発光装置１０は、車体パネルＰと固定部２００ａ、２００ｂによって挟圧されるので、車体パネルＰに対してしっかりと固定される。 Next, when the light emitting device 10 is further pressed toward the vehicle body panel P, the light emitting device 10 advances toward the vehicle body panel P side while the fixing portions 200a and 200b are elastically deformed in the direction in which the fixing portions 200a and 200b are separated from each other, and the tubular portion 80 moves toward the vehicle body panel P. While being in contact with the back surface of the light guide body 94, a part of the light guide body 94 is fitted into the window portion H and is exposed in the vehicle compartment. At this time, the elastically deformed fixing portions 200a and 200b return to the original shape. As a result, the light emitting device 10 is pinched by the vehicle body panel P and the fixing portions 200a and 200b, so that the light emitting device 10 is firmly fixed to the vehicle body panel P.

本実施の形態に係る発光装置１０によれば、ケース本体３６の第１上面４５ａ、４５ｂに基板１４の裏面２８を当接させた状態でカバー部２４の突起部６８ａ、６８ｂの下端面６９ａ、６９ｂを基板１４の実装面１６に押し付けて（圧接させて）いるので、ケース２２に対して基板１４を確実に保持することができる。これにより、発光素子１２と筒部８０の間隔を一定にすることができる。 According to the light emitting device 10 according to the present embodiment, the lower end surfaces 69a of the protrusions 68a and 68b of the cover portion 24 in the state where the back surface 28 of the substrate 14 is in contact with the first upper surfaces 45a and 45b of the case body 36, Since 69b is pressed (pressed against) the mounting surface 16 of the substrate 14, the substrate 14 can be reliably held with respect to the case 22. Thereby, the distance between the light emitting element 12 and the tubular portion 80 can be made constant.

また、導光体２５を筒部８０の内部に装着した状態で導光体本体９４の下端面が第１ストッパ部８６ａ、８６ｂの上端面に当接しているので、導光体２５の基板１４に向かう側の移動が阻止される。これにより、導光体２５が筒部８０の内部に位置決めされる。 Further, since the lower end surface of the light guide body 94 is in contact with the upper end surfaces of the first stopper portions 86a and 86b in a state where the light guide body 25 is mounted inside the tubular portion 80, the substrate 14 of the light guide body 25 is provided. The movement toward the side is blocked. As a result, the light guide 25 is positioned inside the tubular portion 80.

さらに、この状態で、凸部９６ａ、９６ｂの上端面が第２ストッパ部９２ａ、９２ｂの下端面に当接しているので、導光体２５における基板１４が位置する側とは反対側の移動が阻止される。これにより、例えば、筒部８０における基板１４が位置する側とは反対側の開口部が鉛直下方に指向するように発光装置１０の向きを設定した場合であっても、筒部８０に対する導光体２５の位置がずれることはない。これにより、発光装置１０の向きによらず、発光素子１２と導光体２５の距離を一定に保持することができる。 Furthermore, in this state, since the upper end surfaces of the convex portions 96a and 96b are in contact with the lower end surfaces of the second stopper portions 92a and 92b, the movement of the light guide 25 on the side opposite to the side on which the substrate 14 is located can be prevented. Be blocked. Thereby, for example, even when the orientation of the light emitting device 10 is set so that the opening of the tubular portion 80 on the side opposite to the side where the substrate 14 is located is directed vertically downward, the light guide to the tubular portion 80 is performed. The position of the body 25 does not shift. As a result, the distance between the light emitting element 12 and the light guide 25 can be kept constant regardless of the orientation of the light emitting device 10.

本実施の形態では、第１ストッパ部８６ａ、８６ｂと第２ストッパ部９２ａ、９２ｂを利用して導光体２５を筒部８０の内部に位置決め保持しているので、筒部８０の壁部に前記導光体２５を保持するための孔を形成する必要がない。そのため、発光素子１２から発光された光が該孔を介して外部に漏れるような問題も起きない。よって、部品点数の増加を招くことなく発光装置１０の品質を向上させることができる。 In the present embodiment, the light guide 25 is positioned and held inside the tubular portion 80 by using the first stopper portions 86a and 86b and the second stopper portions 92a and 92b, so that the wall portion of the tubular portion 80 is held. It is not necessary to form a hole for holding the light guide 25. Therefore, there is no problem that the light emitted from the light emitting element 12 leaks to the outside through the hole. Therefore, the quality of the light emitting device 10 can be improved without increasing the number of components.

本実施の形態では、第２ストッパ部９２ａ、９２ｂに当接可能な凸部９６ａ、９６ｂを導光体本体９４の外面に一体的に形成しているので、導光体２５を筒部８０の内部に挿入する際に、前記凸部９６ａ、９６ｂを前記第２ストッパ部９２ａ、９２ｂに押し当てて肉厚部位８２ａ、８２ｃを筒部８０の半径方向外方に撓ませることができる。これにより、前記導光体２５を前記筒部８０の内部に一層容易に挿入することができる。 In the present embodiment, since the convex portions 96a and 96b capable of contacting the second stopper portions 92a and 92b are integrally formed on the outer surface of the light guide body 94, the light guide 25 is fixed to the tubular portion 80. When inserted inside, the convex portions 96a and 96b can be pressed against the second stopper portions 92a and 92b to bend the thick portions 82a and 82c outward in the radial direction of the tubular portion 80. Thereby, the light guide 25 can be inserted into the cylindrical portion 80 more easily.

また、導光体２５の凸部９６ａ、９６ｂのテーパ面を第２ストッパ部９２ａ、９２ｂのテーパ面に接触させた状態で導光体２５をベース部６１側に押圧しているので、肉厚部位８２ａ、８２ｃを筒部８０の半径方向外方に容易に撓ませることができる。従って、導光体２５を筒部８０の内部にさらに容易に挿入することができる。 In addition, since the light guide 25 is pressed toward the base 61 while the tapered surfaces of the convex portions 96a and 96b of the light guide 25 are in contact with the tapered surfaces of the second stoppers 92a and 92b, the thickness is increased. The parts 82a and 82c can be easily bent outward in the radial direction of the tubular portion 80. Therefore, the light guide 25 can be inserted into the cylindrical portion 80 more easily.

さらに、一対の第１ストッパ部８６ａ、８６ｂをベース部６１の短手方向に対向して配置すると共に、一対の第２ストッパ部９２ａ、９２ｂをベース部６１の長手方向に対向して配置しているので、例えば、第１ストッパ部８６ａ及び第２ストッパ部９２ａを１つずつ設けた場合（第１ストッパ部８６ｂ及び第２ストッパ部９２ｂを省略した場合）と比較して導光体２５を筒部８０にバランス良く位置決め保持することができる。また、カバー部２４を射出成形により成形する場合に、筒部８０の内部に配置される中子を適当な大きさに分割することで、該中子を該筒部８０の内部から容易に取り出すことができる。 Further, the pair of first stopper portions 86a and 86b are arranged to face each other in the lateral direction of the base portion 61, and the pair of second stopper portions 92a and 92b are arranged to face each other in the longitudinal direction of the base portion 61. Therefore, for example, as compared with the case where the first stopper portion 86a and the second stopper portion 92a are provided one by one (the first stopper portion 86b and the second stopper portion 92b are omitted), The portion 80 can be positioned and held with good balance. Further, when the cover portion 24 is molded by injection molding, the core arranged inside the tubular portion 80 is divided into appropriate sizes, so that the core can be easily taken out from the inside of the tubular portion 80. be able to.

本実施の形態に係る発光装置１０によれば、カバー部２４の一対の突出部６２ａ、６２ｂが発光素子１２を挟むようにして基板１４の実装面１６を押圧すると共に、前記突出部６２ａ、６２ｂのそれぞれに設けられた装着爪７０ａ、７０ｂと装着爪７０ｃ、７０ｄが、側壁部４６ａ、４６ｂのそれぞれに形成された装着孔５２ａ、５２ｂと装着孔５２ｃ、５２ｄに嵌合するので、発光素子１２と筒部８０の間隔を一定に保持することができる。 According to the light emitting device 10 of the present embodiment, the pair of protrusions 62a and 62b of the cover portion 24 presses the mounting surface 16 of the substrate 14 so as to sandwich the light emitting element 12, and the protrusions 62a and 62b respectively. Since the mounting claws 70a, 70b and the mounting claws 70c, 70d provided on the above are fitted into the mounting holes 52a, 52b and the mounting holes 52c, 52d formed in the side wall portions 46a, 46b, respectively, the light emitting element 12 and the cylinder The interval between the parts 80 can be kept constant.

また、本実施の形態では、カバー部２４をケース２２に装着した状態で、カバー部２４の突起部６８ａ、６８ｂの外側面がケース本体３６の第２垂直面４７ａ、４７ｂに接触しているので、カバー部２４と基板１４がその短手方向に相対移動することを好適に抑えることができる。これにより、発光素子１２の光軸を筒部８０の軸線上に位置させることができる。 Further, in the present embodiment, the outer surfaces of the protrusions 68a and 68b of the cover portion 24 are in contact with the second vertical surfaces 47a and 47b of the case body 36 when the cover portion 24 is attached to the case 22. The relative movement of the cover portion 24 and the substrate 14 in the lateral direction can be appropriately suppressed. Thereby, the optical axis of the light emitting element 12 can be located on the axis of the tubular portion 80.

さらにまた、本実施の形態では、端子保持部７２の下端面７３が配置溝５６ａ、５６ｂに収納された接続端子２０ａ、２０ｂのそれぞれのリード部３４に当接しているので、接続端子２０ａ、２０ｂをケース２２に対して好適に保持することができる。 Furthermore, in the present embodiment, since the lower end surface 73 of the terminal holding portion 72 is in contact with the respective lead portions 34 of the connection terminals 20a and 20b housed in the arrangement grooves 56a and 56b, the connection terminals 20a and 20b are provided. Can be suitably held with respect to the case 22.

これにより、接続端子２０ａ、２０ｂを保持するための部品を設ける必要がないので、発光装置１０全体を有効に小型化及び軽量化することができる。また、接続端子２０ａ、２０ｂのそれぞれは、溶着部３０を介して基板１４に固定されているので、該接続端子２０ａ、２０ｂを保持することにより、基板１４の保持が一層安定する。 Accordingly, it is not necessary to provide a component for holding the connection terminals 20a and 20b, so that the entire light emitting device 10 can be effectively reduced in size and weight. Further, since each of the connection terminals 20a and 20b is fixed to the substrate 14 via the welded portion 30, holding the connection terminals 20a and 20b further stabilizes the holding of the substrate 14.

ところで、通常、ケース２２には寸法公差がある。そのため、発光素子１２や接続端子２０ａ、２０ｂ等が実装された基板１４をケース２２内に位置決めした際に、例えば、接続端子２０ａ、２０ｂの各リード部３４が配置溝５６ａ、５６ｂから若干浮き出ることがある。 By the way, the case 22 usually has a dimensional tolerance. Therefore, when the substrate 14 on which the light emitting element 12 and the connection terminals 20a and 20b are mounted is positioned in the case 22, for example, the lead portions 34 of the connection terminals 20a and 20b slightly protrude from the arrangement grooves 56a and 56b. There is.

このような場合であっても、本実施の形態に係る発光装置１０によれば、接続端子２０ａ、２０ｂのそれぞれに湾曲部３２を設けているので、カバー部２４をケース２２に装着した際に、湾曲部３２を撓ませることにより、溶着部３０に余計な応力をかけることなく、接続端子２０ａ、２０ｂを保持することが可能となる。これにより、溶着部３０の接続不良を好適に抑えることができる。 Even in such a case, according to the light emitting device 10 according to the present embodiment, since the curved portions 32 are provided on each of the connection terminals 20a and 20b, when the cover portion 24 is attached to the case 22. By bending the bending portion 32, it is possible to hold the connection terminals 20a and 20b without applying extra stress to the welding portion 30. Thereby, the poor connection of the welded portion 30 can be suppressed appropriately.

また、端子保持部７２の下端面７３に一対の凹部７４ａ、７４ｂを形成しているので、接続端子２０ａ、２０ｂの湾曲部３２がカバー部２４に当たり、該カバー部２４をケース２２に装着し難くなることを防止することができる。さらに、端子保持部７２の下端面７３に一対の凹部７４ａ、７４ｂを形成せずに、前記湾曲部３２と該下端面７３の間に該湾曲部３２が該下端面７３に当たらないように空間を設ける場合と比較して、発光装置１０全体をコンパクトにすることができる。 Further, since the pair of recesses 74a and 74b are formed on the lower end surface 73 of the terminal holding portion 72, the curved portions 32 of the connection terminals 20a and 20b hit the cover portion 24, and it is difficult to attach the cover portion 24 to the case 22. Can be prevented. Further, a space is formed between the curved portion 32 and the lower end surface 73 so that the curved portion 32 does not hit the lower end surface 73 without forming a pair of recesses 74a and 74b on the lower end surface 73 of the terminal holding portion 72. The entire light emitting device 10 can be made compact as compared with the case where the light emitting device 10 is provided.

さらに、本実施の形態では、発光素子１２が実装される基板１４の実装面１６に電子部品１８を配設しているので、電子部品１８を基板１４の裏面２８に実装する場合と比較して、発光装置１０全体を好適に小型化及び軽量化することができる。 Further, in the present embodiment, since the electronic component 18 is arranged on the mounting surface 16 of the substrate 14 on which the light emitting element 12 is mounted, compared with the case where the electronic component 18 is mounted on the back surface 28 of the substrate 14. Therefore, the entire light emitting device 10 can be suitably reduced in size and weight.

本実施の形態に係る発光装置１０において、カバー部２４及び導光体２５に代え、図１０及び図１１に示すようなカバー部１００及び導光体１０２を用いてもよい。この変形例において、上記実施形態の構成要素と同一の構成要素には同一の参照符号を付し、詳細な説明を省略する。 In the light emitting device 10 according to the present embodiment, the cover part 100 and the light guide body 102 as shown in FIGS. 10 and 11 may be used instead of the cover part 24 and the light guide body 25. In this modification, the same components as those of the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

図１０及び図１１に示すように、カバー部１００は、筒部１０４の構成が上述した筒部８０と異なる。具体的には、上述した肉厚部位８２ａの溝部９０ａを省略して肉厚部位８２ａの内周面の上端に第２ストッパ部１０６ａを突設すると共に、肉厚部位８２ｃの溝部９０ｂを省略して肉厚部位８２ｃの内周面の上端に第２ストッパ部１０６ｂを突設している。なお、各第２ストッパ部１０６ａ、１０６ｂは、上端に向かうに従って徐々に先細りするテーパ状に形成されている。 As shown in FIGS. 10 and 11, the cover portion 100 is different in the configuration of the tubular portion 104 from the above-described tubular portion 80. Specifically, the groove portion 90a of the thick portion 82a is omitted, the second stopper portion 106a is provided at the upper end of the inner peripheral surface of the thick portion 82a, and the groove portion 90b of the thick portion 82c is omitted. A second stopper portion 106b is provided at the upper end of the inner peripheral surface of the thick portion 82c. Note that each of the second stopper portions 106a and 106b is formed in a tapered shape that gradually tapers toward the upper end.

筒部１０４では、上述した実施の形態と同様に、肉厚部位８２ｂの内周面の下端部に第１ストッパ部８６ａが形成され、肉厚部位８２ｄの内周面の下端部に第１ストッパ部８６ｂが形成されている。また、導光体１０２では、上述した導光体２５の凸部９６ａ、９６ｂが省略されている。 In the cylindrical portion 104, as in the above-described embodiment, the first stopper portion 86a is formed at the lower end portion of the inner peripheral surface of the thick portion 82b, and the first stopper portion 86a is formed at the lower end portion of the inner peripheral surface of the thick portion 82d. The portion 86b is formed. Further, in the light guide body 102, the convex portions 96a and 96b of the light guide body 25 described above are omitted.

この場合、導光体１０２を筒部１０４の内部に装着した状態で、導光体本体９４の下端面が第１ストッパ部８６ａ、８６ｂの上端面に当接すると共に導光体本体９４の上端面が第２ストッパ部１０６ａ、１０６ｂの下端面に当接することにより、導光体１０２が筒部１０４の内部に位置決め保持することができる。また、本変形例によれば、導光体本体９４の外周面に上述した凸部９６ａ、９６ｂを設ける必要がないので、導光体１０２を簡易な構成にすることができる。その結果、発光装置１０の製造コストの低減を図ることができる。 In this case, the lower end surface of the light guide body 94 abuts on the upper end surfaces of the first stopper portions 86a and 86b and the upper end surface of the light guide body 94 in a state where the light guide body 102 is mounted inside the tubular portion 104. By contacting the lower end surfaces of the second stopper portions 106a and 106b with each other, the light guide body 102 can be positioned and held inside the cylindrical portion 104. Further, according to this modification, since it is not necessary to provide the above-described convex portions 96a and 96b on the outer peripheral surface of the light guide body 94, the light guide 102 can have a simple configuration. As a result, the manufacturing cost of the light emitting device 10 can be reduced.

本実施の形態は、上述した構成に限らず、例えば、発光装置１０は、複数の発光素子１２を基板１４に実装して構成されていても構わない。 The present embodiment is not limited to the configuration described above, and for example, the light emitting device 10 may be configured by mounting a plurality of light emitting elements 12 on the substrate 14.

本実施の形態に係る発光装置１０は、突起部６８ａ、６８ｂの下端面６９ａ、６９ｂから装着爪７０ａ、７０ｂ、７０ｃ、７０ｄの上端面までの距離Ｌ１を、基板１４の実装面１６から装着孔５２ａ、５２ｂ、５２ｃ、５２ｄの上端部までの距離Ｌ２と同一に設定してもよい。この場合、基板１４は、突起部６８ａ、６８ｂによって殆ど押圧されないが、突起部６８ａ、６８ｂの下端面６９ａ、６９ｂと基板１４の実装面１６との接触抵抗によって、基板１４をケース本体３６に対して保持することができる。 In the light emitting device 10 according to the present embodiment, the distance L1 from the lower end surfaces 69a, 69b of the protrusions 68a, 68b to the upper end surfaces of the mounting claws 70a, 70b, 70c, 70d is set from the mounting surface 16 of the substrate 14 to the mounting hole. The distance L2 to the upper ends of 52a, 52b, 52c and 52d may be set to be the same. In this case, the substrate 14 is hardly pressed by the protrusions 68a and 68b, but the contact resistance between the lower end surfaces 69a and 69b of the protrusions 68a and 68b and the mounting surface 16 of the substrate 14 causes the substrate 14 to move against the case body 36. Can be held.

本実施の形態では、装着爪７０ａ、７０ｂ、７０ｃ、７０ｄに代えてカバー部２４の突出部６２ａ、６２ｂに装着孔を形成し、装着孔５２ａ、５２ｂ、５２ｃ、５２ｄに代えてケース本体３６の側壁部４６ａ、４６ｂに装着爪を設けてもよい。この場合にもカバー部２４をケース２２に対して容易に装着することができる。 In the present embodiment, mounting holes are formed in the projecting portions 62a and 62b of the cover part 24 in place of the mounting claws 70a, 70b, 70c, and 70d, and the mounting holes 52a, 52b, 52c, and 52d are replaced by the case main body 36. Mounting claws may be provided on the side walls 46a and 46b. Also in this case, the cover portion 24 can be easily attached to the case 22.

装着孔５２ａ〜５２ｄ、装着爪７０ａ〜７０ｄ、及び、固定爪５４ａ、５４ｂの数量・位置・形状は、適宜変更可能である。また、第１ストッパ部８６ａ、８６ｂ、第２ストッパ部９２ａ、９２ｂ、１０６ａ、１０６ｂ、及び、凸部９６ａ、９６ｂの数量・位置・形状は、適宜変更可能である。 The numbers, positions, and shapes of the mounting holes 52a to 52d, the mounting claws 70a to 70d, and the fixed claws 54a and 54b can be appropriately changed. Further, the numbers, positions, and shapes of the first stopper portions 86a, 86b, the second stopper portions 92a, 92b, 106a, 106b, and the convex portions 96a, 96b can be appropriately changed.

本実施の形態に係る筒部８０は、樹脂材料で構成される例に限らず、任意の材料で構成してよい。例えば、筒部８０は、鉄等の金属材料で構成してもよい。この場合、例えば、筒部８０の厚みを調節する（筒部８０を肉薄に形成する）ことにより、導光体２５を筒部８０の内部に挿入する際に該筒部８０を半径方向外方に好適に撓ませることが可能である。なお、筒部１０４についても同様に任意の材料で構成してよい。 The tubular portion 80 according to the present embodiment is not limited to the example made of the resin material, and may be made of any material. For example, the tubular portion 80 may be made of a metal material such as iron. In this case, for example, by adjusting the thickness of the tubular portion 80 (making the tubular portion 80 thin), when the light guide 25 is inserted into the tubular portion 80, the tubular portion 80 is radially outward. It is possible to bend it appropriately. The cylindrical portion 104 may be similarly made of any material.

本発明は上記した実施形態に限らず、本発明の要旨を逸脱することなく、種々の構成を採り得ることは当然可能である。本発明に係る発光装置は、車両室内の照明用に限定されない。 The present invention is not limited to the above-described embodiment, and it is naturally possible to adopt various configurations without departing from the gist of the present invention. The light emitting device according to the present invention is not limited to lighting for a vehicle interior.
