Has been. A concave portion 67 is formed in the arc portion 64 in the longitudinal direction, and a screw hole 65a (see FIG. 4) is formed between the screw fixing portion 65 and the jig fixing portion 66.

Further, the end portions of the side wall portion 63 in the instrument side direction are respectively integrated with both end portions of the arc portion 64. The curvature of the arc portion 64 is substantially the same as the curvature of the inner peripheral surface of the cover 2, and the arc portion 64 faces the inner peripheral surface of the cover 2 when the light source module 3 is held inside the cover 2.
　光源設置部６１の器具側の面には、４つの治具固定部６６が器具側へ長手方向に渡って突出して設けられており、さらに円弧部６４の出射側の面には、ねじ固定部６５が出射側へ長手方向に渡って突出して設けられている。治具固定部６６のうち光源４近傍の２つの治具固定部６６と、ねじ固定部６５の間にはねじ孔６５ａが形成されている。保持口金筐体７１に形成されたねじ孔７３又は給電口金筐体８１に形成されたねじ孔８３に挿入されたねじ９がねじ孔６５ａに挿入されることにより、光源モジュール３の一部であるヒートシンク６と保持口金７０又は給電口金８０とが固定される。また、ヒートシンク６がカバー２の内部に固定されている状態でヒートシンク６に保持口金７０又は給電口金８０が固定されると、保持口金７０はカバー２の一方の端部を覆うように固定され、給電口金８０はカバー２の他方の端部を覆うように固定される。 On the surface of the light source installation portion 61 on the instrument side, four jig fixing portions 66 are provided so as to protrude in the longitudinal direction toward the instrument side, and on the surface on the emission side of the arc portion 64, a screw fixing portion is provided. 65 is provided to protrude in the longitudinal direction toward the emission side. A screw hole 65 a is formed between the two jig fixing parts 66 in the vicinity of the light source 4 of the jig fixing part 66 and the screw fixing part 65. The screw 9 inserted into the screw hole 73 formed in the holding base casing 71 or the screw hole 83 formed in the power supply base casing 81 is inserted into the screw hole 65a, thereby being a part of the light source module 3. The heat sink 6 and the holding base 70 or the power supply base 80 are fixed. Further, when the holding base 70 or the power supply base 80 is fixed to the heat sink 6 in a state where the heat sink 6 is fixed inside the cover 2, the holding base 70 is fixed so as to cover one end of the cover 2, The power supply cap 80 is fixed so as to cover the other end of the cover 2.
　凹部６７は２つの面の断面形状が略Ｖ字型となるように形成された溝であり、ヒートシンク６の長手方向（矢印Ｘの方向）に対して並行に伸びるよう形成されている。凹部６７には、図６で示すように接着部材１０がヒートシンク６の長手方向に沿って設けられており、接着部材１０によってヒートシンク６はカバー２の内周面に接着固定されている。実施の形態１の接着部材１０には、シリコーン樹脂系接着剤などの硬化するまで流動性を有する接着剤を用いている。 The recess 67 is a groove formed so that the cross-sectional shapes of the two surfaces are substantially V-shaped, and is formed to extend in parallel to the longitudinal direction of the heat sink 6 (the direction of the arrow X). As shown in FIG. 6, the adhesive member 10 is provided in the recess 67 along the longitudinal direction of the heat sink 6, and the heat sink 6 is bonded and fixed to the inner peripheral surface of the cover 2 by the adhesive member 10. The adhesive member 10 of the first embodiment uses an adhesive having fluidity until it is cured, such as a silicone resin adhesive.
　ヒートシンク６の断面形状は一定の形状であるため、押出成形を用いた製造が適している。なお、凹部６７は押出成形時に形成しても構わないし、押出成形では凹部６７が形成されていない断面形状で成形してから加工によって凹部６７を形成しても構わない。また、断面形状は略Ｖ字型に限らず、円弧型、Ｕ字型、Ｍ字型などの断面形状であってもよい。 Since the cross-sectional shape of the heat sink 6 is a fixed shape, manufacturing using extrusion molding is suitable. The recess 67 may be formed at the time of extrusion molding, or the recess 67 may be formed by processing after forming in a cross-sectional shape where the recess 67 is not formed by extrusion molding. The cross-sectional shape is not limited to a substantially V shape, and may be a cross-sectional shape such as an arc shape, a U shape, or an M shape.
　次に照明ランプ１を組み立てる手順について説明する。 Next, the procedure for assembling the lighting lamp 1 will be described.
ステップ１．
　まず、ステップ１として、複数の光源４と、基板５と、ヒートシンク６とを一体化させ、光源モジュール３を組み立てる。具体的には、基板５の配線パターンに従って光源４を実装し、光源４を実装した基板５をヒートシンク６の光源設置部６１に設置する。なお、光源設置部６１に基板５を設置する方法としては、接着剤あるいは両面テープ等によって接着する方法や、基板５と光源設置部６１にねじ孔を設けねじ止めする方法等が挙げられる。 Step 1.
First, as step 1, a plurality of light sources 4, a substrate 5, and a heat sink 6 are integrated to assemble a light source module 3. Specifically, the light source 4 is mounted according to the wiring pattern of the substrate 5, and the substrate 5 on which the light source 4 is mounted is installed on the light source installation unit 61 of the heat sink 6. Examples of the method of installing the substrate 5 on the light source installation unit 61 include a method of adhering with an adhesive or a double-sided tape, a method of providing a screw hole on the substrate 5 and the light source installation unit 61, and screwing.
ステップ２．
　ステップ１で光源モジュール３を組み立てた後、ステップ２に進み、ヒートシンク６の凹部６７に沿って光源モジュール３の長手方向に対し並行に接着部材１０を設ける。接着部材１０が流動性を有するシリコーン樹脂系接着剤の場合は、例えば、ノズルなどを用いて射出量が管理された接着部材１０が凹部６７に沿って付設される。凹部６７は、前述の通りヒートシンク６の長手方向、つまり光源モジュール３の長手に対して並行に伸びるよう形成されている。このため、凹部６７は接着部材１０を設ける際の目印として機能し、凹部６７に沿って接着部材１０を設けることで複数の照明ランプ１において略同一の位置に接着部材１０を照明ランプ１の長手方向に対して並行に設け易くなっている。 Step 2.
After assembling the light source module 3 in step 1, the process proceeds to step 2, and the adhesive member 10 is provided in parallel to the longitudinal direction of the light source module 3 along the recess 67 of the heat sink 6. In the case where the adhesive member 10 is a silicone resin adhesive having fluidity, for example, the adhesive member 10 whose injection amount is controlled using a nozzle or the like is provided along the recess 67. As described above, the recess 67 is formed to extend in parallel to the longitudinal direction of the heat sink 6, that is, the longitudinal direction of the light source module 3. For this reason, the concave portion 67 functions as a mark when the adhesive member 10 is provided. By providing the adhesive member 10 along the concave portion 67, the longitudinal direction of the illumination lamp 1 is set at approximately the same position in the plurality of illumination lamps 1. It is easy to provide parallel to the direction.
ステップ３．
　ステップ２で接着部材１０を凹部６７に設けた後、ステップ３に進み、接着部材１０が硬化する前に光源モジュール３をカバー２の内部に挿入し、ヒートシンク６の円弧部６４とカバー２の内周面とを接着部材１０を介して密着させる。接着部材１０は硬化するまで流動性を有する接着剤を使用しており、また接着部材１０は凹部６７に設けられているため、ヒートシンク６をカバー２の内周面に密着させる際に、凹部６７に接着部材１０を捕捉させ、接着部材１０が凹部６７の外側にはみ出すことを防ぐことができる。 Step 3.
After the adhesive member 10 is provided in the recess 67 in step 2, the process proceeds to step 3 and the light source module 3 is inserted into the cover 2 before the adhesive member 10 is cured, and the arc portion 64 of the heat sink 6 and the cover 2 The peripheral surface is brought into close contact with the adhesive member 10. The adhesive member 10 uses an adhesive having fluidity until it is cured, and the adhesive member 10 is provided in the concave portion 67. Therefore, when the heat sink 6 is brought into close contact with the inner peripheral surface of the cover 2, the concave portion 67 is used. It is possible to prevent the adhesive member 10 from protruding outside the recess 67 by capturing the adhesive member 10.
ステップ４．
　ステップ３でカバー２とヒートシンク６とを接着部材１０を介して密着させた後、ステップ４に進み、接着部材１０を硬化させる。カバー２とヒートシンク６とを接着部材１０を介して密着させた状態で接着部材１０を硬化させることによって、光源モジュール３はカバー２の内周面に接着固定される。なお、接着部材１０は、加熱、送風などの方法を用いることによって硬化する時間を短縮させることができる。 Step 4.
After the cover 2 and the heat sink 6 are brought into close contact with each other through the adhesive member 10 in Step 3, the process proceeds to Step 4 where the adhesive member 10 is cured. The light source module 3 is bonded and fixed to the inner peripheral surface of the cover 2 by curing the adhesive member 10 in a state where the cover 2 and the heat sink 6 are in close contact with each other via the adhesive member 10. Note that the adhesive member 10 can be cured by using a method such as heating or air blowing.
ステップ５．
　ステップ４で接着部材１０を硬化させた後、ステップ５に進み、カバー２の両端の開口に保持口金７及び給電口金８を取り付ける。具体的には、保持口金７及び給電口金８のそれぞれのねじ孔７３，８３を、ヒートシンク６のねじ孔６５ａと照明ランプ１の長手方向の向きに一直線上に配置する。この状態で、ねじ孔７３，８３よりねじ９をねじ孔６５まで挿入し、ねじ止めすることによって、保持口金７及び給電口金８はカバー２の両端の開口を覆うようにヒートシンク６を介してカバー２に取り付けられる。また、給電口金８の給電端子８２と基板５の配線パターンとは電気的に接続された状態で、給電端子８２はカバー２に取り付けられる。なお、ステップ５において、保持口金筐体７１及び給電口金筐体８１に接着剤あるいは両面テープ等を設け、保持口金７並びに給電口金８をカバー２に直接接着して、より強固に取り付けても構わない。 Step 5.
After the adhesive member 10 is cured in step 4, the process proceeds to step 5, and the holding base 7 and the power supply base 8 are attached to the openings at both ends of the cover 2. Specifically, the screw holes 73 and 83 of the holding base 7 and the power supply base 8 are arranged in a straight line in the longitudinal direction of the screw hole 65 a of the heat sink 6 and the illumination lamp 1. In this state, the screw 9 is inserted from the screw holes 73 and 83 to the screw hole 65 and fixed, whereby the holding base 7 and the power supply base 8 are covered via the heat sink 6 so as to cover the openings at both ends of the cover 2. 2 is attached. Further, the power supply terminal 82 is attached to the cover 2 in a state where the power supply terminal 82 of the power supply base 8 and the wiring pattern of the substrate 5 are electrically connected. In step 5, the holding base casing 71 and the power supply base casing 81 may be provided with an adhesive or a double-sided tape, and the holding base 7 and the power supply base 8 may be directly bonded to the cover 2 to be attached more firmly. Absent.
　ステップ５でカバー２の両端の開口に保持口金７及び給電口金８を取り付けることによって、照明ランプ１の組み立てが完了する。 At step 5, the attachment of the holding base 7 and the power supply base 8 to the openings at both ends of the cover 2 completes the assembly of the illumination lamp 1.
　以上より、実施の形態１の照明ランプ１は、ヒートシンク６の円弧部６４、つまり光源モジュール３の表面のうちカバー２の内周面に対向する表面に照明ランプ１の長手方向に並行に伸びる凹部６７を形成することによって、凹部６７が接着部材１０を設ける際の目印として機能し、凹部６７に沿って接着部材１０を設けることで複数の照明ランプ１において略同一の位置に接着部材１０を照明ランプ１の長手方向に対して並行に設け易くなっている。このため、均一な品質の照明ランプ１を容易に量産することができる。 As described above, the illumination lamp 1 of the first embodiment has the arc portion 64 of the heat sink 6, that is, the recess extending in parallel with the longitudinal direction of the illumination lamp 1 on the surface of the light source module 3 that faces the inner peripheral surface of the cover 2. By forming 67, the recess 67 functions as a mark when the adhesive member 10 is provided, and the adhesive member 10 is provided along the recess 67 to illuminate the adhesive member 10 at substantially the same position in the plurality of illumination lamps 1. It is easy to provide parallel to the longitudinal direction of the lamp 1. For this reason, the uniform quality illumination lamp 1 can be easily mass-produced.
　また、接着部材１０は硬化するまで流動性を有する接着剤を用いているため、光源モジュール３をカバー２の内周面に密着させる際に、凹部６７が接着部材１０を捕捉し、円弧部６４まで接着部材１０がはみ出し難くなる。カバー２は透光性を有しているので接着部材１０は使用者が視認することができ、接着部材１０が円弧部６４にはみ出してしまうと照明ランプ１の意匠性を損ねてしまう。このため、実施の形態１の照明ランプ１は接着部材１０のはみ出しによる意匠性の低下が発生し難くなる。 Further, since the adhesive member 10 uses a fluid adhesive until it is cured, when the light source module 3 is brought into close contact with the inner peripheral surface of the cover 2, the concave portion 67 captures the adhesive member 10 and the arc portion 64. It becomes difficult for the adhesive member 10 to protrude. Since the cover 2 has translucency, the user can visually recognize the adhesive member 10. If the adhesive member 10 protrudes from the arc portion 64, the design of the illumination lamp 1 is impaired. For this reason, in the illumination lamp 1 according to the first embodiment, it is difficult for the designability to deteriorate due to the protrusion of the adhesive member 10.
　なお、実施の形態１の照明ランプ１の接着部材１０には、硬化するまで流動性を有する接着剤を用いているが、これに限らず、粘着テープ等のようにカバー２の内周面に光源モジュール３を固定することができる物質であれば良い。 In addition, although the adhesive agent which has fluidity | liquidity is used for the adhesive member 10 of the illumination lamp 1 of Embodiment 1 until it hardens | cures, it is not restricted to this, On the inner peripheral surface of the cover 2 like an adhesive tape etc. Any substance that can fix the light source module 3 may be used.
　また、実施の形態１の照明ランプ１は、上述したステップ１から５の手順で組み立てを行っているが、凹部６７に沿って接着部材１０を設ける工程（ステップ２）と、設けた接着部材１０が硬化する前にカバー２とヒートシンク６とを接着部材１０を介して密着させる工程（ステップ３）と、カバー２とヒートシンク６とが接着部材１０を介して密着した状態で接着部材１０が硬化する工程（ステップ４）を備えていれば、これに限らない。さらに、接着部材１０が粘着テープ等のように硬化せずにカバー２と光源モジュール３を固定することが可能な物質であるならば、ステップ４を備えていなくても構わない。 Moreover, although the illumination lamp 1 of Embodiment 1 is assembled in the procedure of step 1 to 5 mentioned above, the process (step 2) which provides the adhesive member 10 along the recessed part 67, and the provided adhesive member 10 are provided. The adhesive member 10 is cured in a state in which the cover 2 and the heat sink 6 are in close contact with each other through the adhesive member 10 (step 3), and the cover 2 and the heat sink 6 are in close contact with each other through the adhesive member 10 before the adhesive is cured. If it has a process (Step 4), it will not be restricted to this. Further, if the adhesive member 10 is a substance capable of fixing the cover 2 and the light source module 3 without being cured, such as an adhesive tape, the step 4 may not be provided.
実施の形態２．
　図９は、実施の形態２に係る照明ランプの側面図である。図１０は、実施の形態２に係る照明ランプの底面図である。図１１は、実施の形態２に係る照明ランプの図９及び図１０に示すＢ－Ｂ断面を示す断面図である。図１２は、実施の形態２に係るヒートシンクの他方の端部の拡大斜視図である。実施の形態２の照明ランプ１ａは、実施の形態１の照明ランプ１と比べて、ヒートシンク６ａの凹部６７が２ヶ所に形成され、それぞれに接着部材１０が設けられている点が異なっている。なお、その他の構成については実施の形態１と略同様であるため、説明を割愛する。 Embodiment 2. FIG.
FIG. 9 is a side view of the illumination lamp according to the second embodiment. FIG. 10 is a bottom view of the illumination lamp according to the second embodiment. FIG. 11 is a cross-sectional view showing the BB cross section shown in FIGS. 9 and 10 of the illumination lamp according to the second embodiment. FIG. 12 is an enlarged perspective view of the other end of the heat sink according to the second embodiment. The illumination lamp 1a according to the second embodiment is different from the illumination lamp 1 according to the first embodiment in that the recesses 67 of the heat sink 6a are formed in two places and the adhesive member 10 is provided in each of them. Since other configurations are substantially the same as those in the first embodiment, the description thereof is omitted.
　実施の形態２においても、凹部６７はヒートシンク６ａの長手方向（矢印Ｘの方向）に対して並行に伸びるようそれぞれ形成されている。このため、実施の形態１と同様にそれぞれの凹部６７は着部材１０を設ける際の目印として機能し、略同一の位置に接着部材１０を照明ランプ１ａの長手方向に対して並行に設け易くなっている。また、実施の形態１に比べて、接着部材１０を設ける箇所が増えているため、より強固に光源モジュール３をカバー２に固定することができる。 Also in the second embodiment, the recesses 67 are formed so as to extend in parallel to the longitudinal direction of the heat sink 6a (the direction of the arrow X). For this reason, each recessed part 67 functions as a mark at the time of providing the attachment member 10 similarly to Embodiment 1, and it becomes easy to provide the adhesion member 10 in the longitudinal direction of the illumination lamp 1a in the substantially same position. ing. Moreover, since the location where the adhesive member 10 is provided is increased as compared with the first embodiment, the light source module 3 can be more firmly fixed to the cover 2.
実施の形態３．
　本発明におけるヒートシンクの凹部６７、又は凹部６７と対向するカバー２の内周面の、接着部材１０によって相互に接着固定される部分には、例えばサンドブラスト法などの方法によって表面処理が施され微細な凹凸が形成されてもよい（図示省略）。このような構成にすることによって、接着部材１０を接する面積を増やすことができるため、より強固に光源モジュール３をカバー２に固定することができる。なお、カバー２の内周面に形成された微細な凹凸は、カバー２を透過する光を拡散させる機能を備えて、構造的な機能と光学的な機能とを兼ねるものであってもよい。 Embodiment 3 FIG.
In the present invention, the concave portion 67 of the heat sink or the portion of the inner peripheral surface of the cover 2 facing the concave portion 67 that is bonded and fixed to each other by the adhesive member 10 is subjected to a surface treatment, for example, by a sandblasting method or the like. Concavities and convexities may be formed (not shown). By adopting such a configuration, the area in contact with the adhesive member 10 can be increased, so that the light source module 3 can be more firmly fixed to the cover 2. The fine irregularities formed on the inner peripheral surface of the cover 2 may have a function of diffusing light transmitted through the cover 2 and may have both a structural function and an optical function.
