次に、光源ユニット２の組立手順について説明する。   Next, the assembly procedure of the light source unit 2 will be described.

まず最初に、作業者は、基板２１の下面に実装されたＬＥＤチップ２１０を取付部材２３のベース部２３１の開口部２３１１を通して下側に露出させた状態で、基板２１をベース部２３１の上面に載せる。さらに、作業者は、導体２７，２７の一端に接続された第１接続端子２６，２６をそれぞれコネクタ部２３２の収納部２３２２，２３２２に収納した後、導体２７，２７の他端をそれぞれ基板２１の電極２１１，２１１に半田接続する。このとき、導体２７，２７は、ベース部２３１に形成された溝２３１２，２３１３にそれぞれ配置される。   First, the operator places the substrate 21 on the upper surface of the base portion 231 in a state where the LED chip 210 mounted on the lower surface of the substrate 21 is exposed downward through the opening 2311 of the base portion 231 of the mounting member 23. Put it on. Further, the operator stores the first connection terminals 26 and 26 connected to one ends of the conductors 27 and 27 in the storage portions 2322 and 2322 of the connector portion 232, respectively, and then connects the other ends of the conductors 27 and 27 to the substrate 21. The electrodes 211 and 211 are connected by soldering. At this time, the conductors 27 and 27 are respectively disposed in the grooves 2312 and 2313 formed in the base portion 231.

続けて、作業者は、ベース部２３１に載せた基板２１の上面に放熱シート２５を載せた後、ベース部２３１の上面と放熱部材２４の底壁部２４１の下面とが密着するようにして取付部材２３を放熱部材２４に取り付ける。   Subsequently, the operator places the heat radiation sheet 25 on the upper surface of the substrate 21 placed on the base portion 231, and then attaches the upper surface of the base portion 231 and the lower surface of the bottom wall portion 241 of the heat radiating member 24 in close contact with each other. The member 23 is attached to the heat radiating member 24.

このとき、取付部材２３のベース部２３１に設けた貫通孔２３２７，２３２７にそれぞれ通した取付ねじ（図示せず）を、放熱部材２４の底壁部２４１に設けたねじ孔２４１１，２４１１にそれぞれねじ込むことで、取付部材２３が放熱部材２４に取り付けられる。またこのとき、コネクタ部２３２は、底壁部２４１に設けられた切欠部２４１２を通して上側に突出する。さらにこのとき、放熱シート２５は、放熱部材２４の底壁部２４１に密着しており、基板２１のＬＥＤチップ２１０で発生した熱が放熱シート２５を介して放熱部材２４に伝えられる。   At this time, mounting screws (not shown) passed through the through holes 2327 and 2327 provided in the base portion 231 of the mounting member 23 are screwed into screw holes 2411 and 2411 provided in the bottom wall portion 241 of the heat radiating member 24, respectively. Thus, the attachment member 23 is attached to the heat dissipation member 24. At this time, the connector part 232 protrudes upward through the notch part 2412 provided in the bottom wall part 241. Further, at this time, the heat radiating sheet 25 is in close contact with the bottom wall portion 241 of the heat radiating member 24, and heat generated in the LED chip 210 of the substrate 21 is transmitted to the heat radiating member 24 through the heat radiating sheet 25.

そして最後に、作業者は、レンズ２２の軸方向が上下方向となり且つ鍔部２２２側が上側となるように向きを調整した状態でレンズ２２を取付部材２３に押し付け、レンズ２２を取付部材２３に取り付ける。これにより、光源ユニット２の組み立てが完了する。   Finally, the operator presses the lens 22 against the mounting member 23 with the orientation adjusted so that the axial direction of the lens 22 is in the vertical direction and the flange 222 side is on the upper side, and the lens 22 is attached to the mounting member 23. . Thereby, the assembly of the light source unit 2 is completed.

このとき、レンズ２２を取付部材２３に押し付けることで、レンズ２２の鍔部２２２により固定部２３１４〜２３１７の固定爪２３１４ａ〜２３１７ａが外向きに押され、固定部２３１４〜２３１７が外向きに撓められる。そして、レンズ２２を取付部材２３にさらに押し付けることで、レンズ２２の鍔部２２２が固定爪２３１４ａ〜２３１７ａを乗り越え、レンズ２２の上面（入射面）がリブ２３２３〜２３２６に接触する。   At this time, by pressing the lens 22 against the mounting member 23, the fixing claws 2314 a to 2317 a of the fixing portions 2314 to 2317 are pushed outward by the flange portion 222 of the lens 22, and the fixing portions 2314 to 2317 are bent outward. It is done. Then, by further pressing the lens 22 against the mounting member 23, the flange portion 222 of the lens 22 gets over the fixing claws 2314a to 2317a, and the upper surface (incident surface) of the lens 22 contacts the ribs 2323 to 2326.

そして、固定部２３１４〜２３１７が弾性力によって元の位置に復帰することで、固定部２３１４〜２３１７の固定爪２３１４ａ〜２３１７ａとリブ２３２３〜２３２６との間に鍔部２２２が挟まれ、レンズ２２が取付部材２３に取り付けられる。   Then, the fixing portions 2314 to 2317 return to their original positions by the elastic force, so that the flange portion 222 is sandwiched between the fixing claws 2314a to 2317a and the ribs 2323 to 2326 of the fixing portions 2314 to 2317, and the lens 22 is It is attached to the attachment member 23.

レンズ２２が取付部材２３に取り付けられた状態では、レンズ２２の上面がリブ２３２３〜２３２６の下面に接触している。また、ベース部２３１の周方向においてリブ２３２３〜２３２６がない部分では、レンズ２２の鍔部２２２がガイド部２３１８〜２３２１に接触している。その結果、レンズ２２の上面とベース部２３１の下面との間の隙間に塵埃が進入するのを抑えることができる。   In a state where the lens 22 is attached to the attachment member 23, the upper surface of the lens 22 is in contact with the lower surfaces of the ribs 2323 to 2326. Further, in a portion where the ribs 2323 to 2326 are not provided in the circumferential direction of the base portion 231, the flange portion 222 of the lens 22 is in contact with the guide portions 2318 to 2321. As a result, it is possible to prevent dust from entering the gap between the upper surface of the lens 22 and the lower surface of the base portion 231.
