Further, a guide portion 2320 that protrudes downward from the lower surface of the base portion 231 and is curved in an arc shape is provided between the fixing portion 2315 and the fixing portion 2316 in the circumferential direction of the base portion 231.

また、ベース部２３１の周方向における固定部２３１６と固定部２３１７との間には、ベース部２３１の下面から下向きに突出し且つ弧状に湾曲するガイド部２３２１が設けられている。さらに、ベース部２３１の周方向における固定部２３１７と固定部２３１４との間には、ベース部２３１の下面から下向きに突出し且つ弧状に湾曲するガイド部２３１８が設けられている。   A guide portion 2321 that protrudes downward from the lower surface of the base portion 231 and is curved in an arc shape is provided between the fixing portion 2316 and the fixing portion 2317 in the circumferential direction of the base portion 231.

これらのガイド部２３１８〜２３２１は、取付部材２３のベース部２３１にレンズ２２を取り付ける際のガイドとして機能する。また、各ガイド部２３１８〜２３２１の先端には、先端に近づくほど厚みが薄くなるように傾斜するテーパがつけられており、このテーパによってレンズ２２をガイド部２３１８〜２３２１に誘いやすくなっている。   These guide portions 2318 to 2321 function as guides when the lens 22 is attached to the base portion 231 of the attachment member 23. Further, the tips of the respective guide portions 2318 to 2321 are tapered such that the thickness thereof becomes thinner as the distance from the guide portions 2318 to 2321 is approached, and this taper makes it easy to invite the lens 22 to the guide portions 2318 to 2321.

また、ベース部２３１の上面には、図４Ｂに示すように、開口部２３１１の周りを取り囲むように溝２３２８が形成されており、光源ユニット２を組み立てた状態では、基板２１の上面に密着した状態で放熱シート２５が溝２３２８内に収納される。   Further, as shown in FIG. 4B, a groove 2328 is formed on the upper surface of the base portion 231 so as to surround the opening portion 2311. When the light source unit 2 is assembled, the groove is closely attached to the upper surface of the substrate 21. In the state, the heat dissipation sheet 25 is stored in the groove 2328.

放熱部材２４は、例えば放熱性の高いアルミニウムからなり、前後方向に長い矩形板状に形成された底壁部２４１と、底壁部２４１の前後方向における両端から下向きに突出する一対の側壁部２４２，２４４とを有する。一方の側壁部２４２には、非常用電源４のケース４１に設けられた引掛部４１１の引掛爪４１１１が引っ掛けられる矩形の引掛孔２４２１が設けられている。また、他方の側壁部２４４には、電源装置３のケース３１に設けられた引掛部３１１の引掛爪（図示せず）が引っ掛けられる矩形の引掛孔（図示せず）が設けられている。   The heat radiating member 24 is made of, for example, aluminum having high heat radiating property, and has a bottom wall portion 241 formed in a rectangular plate shape long in the front-rear direction, and a pair of side wall portions 242 protruding downward from both ends in the front-rear direction of the bottom wall portion 241. , 244.

An extending portion 245 extending in parallel with the portion 241 is provided integrally.

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が挟まれて、レンズ２２が取付部材２３に取り付けられる。   Then, when the fixing portions 2314 to 2317 are returned to their original positions by the elastic force, 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 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.

次に、照明器具１０の施工手順について説明する。   Next, the construction procedure of the lighting fixture 10 will be described.

まず最初に、作業者は、電源装置３が右側、非常用電源４が左側となるように配置した後、図示しない接続構造により電源装置３と非常用電源４とを機械的且つ電気的に接続する。そして、作業者は、機械的且つ電気的に接続された電源装置３及び非常用電源４を器具本体１の内部に収納する。   First, the worker arranges the power supply device 3 on the right side and the emergency power supply 4 on the left side, and then mechanically and electrically connects the power supply device 3 and the emergency power supply 4 with a connection structure (not shown). To do. Then, the worker stores the power supply device 3 and the emergency power supply 4 that are mechanically and electrically connected to each other inside the instrument main body 1.

電源装置３と非常用電源４とを組み付けた状態では、下面中央に収納部１００が形成され、作業者は、レンズ２２が下側となる向きで光源ユニット２を収納部１００に収納する。このとき、光源ユニット２は、リブ３１２，４１２によって左右方向に位置決めされた状態で収納部１００に収納される。   In a state in which the power supply device 3 and the emergency power supply 4 are assembled, the storage unit 100 is formed at the center of the lower surface, and the operator stores the light source unit 2 in the storage unit 100 with the lens 22 facing downward. At this time, the light source unit 2 is stored in the storage unit 100 while being positioned in the left-right direction by the ribs 312 and 412.

そして、作業者が光源ユニット２を収納部１００の所定位置まで押し込むと、光源ユニット２が電源装置３及び非常用電源４に保持される。このとき、放熱部材２４の側壁部２４２の引掛孔２４２１にケース４１の引掛部４１１の引掛爪４１１１が引っ掛けられ、且つ、側壁部２４４の引掛孔（図示せず）にケース３１の引掛部３１１の引掛爪（図示せず）が引っ掛けられる。ここに、本実施形態では、ケース３１に設けた引掛部３１１とケース４１に設けた引掛部４１１とで保持部が構成されている。   When the operator pushes the light source unit 2 to a predetermined position in the storage unit 100, the light source unit 2 is held by the power supply device 3 and the emergency power supply 4. At this time, the hooking claw 4111 of the hooking portion 411 of the case 41 is hooked in the hooking hole 2421 of the side wall portion 242 of the heat radiating member 24, and the hooking portion 311 of the case 31 is hooked in the hooking hole (not shown) of the side wall portion 244. A hooking claw (not shown) is hooked. Here, in this embodiment, the holding portion is configured by the hook portion 311 provided in the case 31 and the hook portion 411 provided in the case 41.

そして最後に、作業者は、器具本体１の開口部１１１を塞ぐようにカバー５を器具本体１に取り付ける。このとき、カバー５に取り付けられた各取付ばね７が、器具本体１の対応するばね受け部１１３，１１３に引っ掛けられ、カバー５が器具本体１に保持される。   Finally, the operator attaches the cover 5 to the instrument body 1 so as to close the opening 111 of the instrument body 1. At this time, each attachment spring 7 attached to the cover 5 is hooked on the corresponding spring receiving portions 113, 113 of the instrument body 1, and the cover 5 is held by the instrument body 1.

本実施形態の光源ユニット２によれば、ＬＥＤチップ２１０から放射される光の配光を変更する際には、レンズ２２を交換するだけでよく、従来例のようにランプ装置全体を交換しなくてもいいことから、コストアップを抑えることができる。また、本実施形態のように、ガイド部２３１８〜２３２１を取付部材２３に設けることによって、レンズ２２を取付部材２３に取り付ける際に取り付けやすくなるという利点がある。   According to the light source unit 2 of this embodiment, when changing the light distribution of the light emitted from the LED chip 210, it is only necessary to replace the lens 22, and not to replace the entire lamp device as in the conventional example. It is okay to reduce the cost. Further, by providing the guide portions 2318 to 2321 on the attachment member 23 as in the present embodiment, there is an advantage that it is easy to attach the lens 22 to the attachment member 23.

図５は本実施形態の別の照明器具１０の分解斜視図である。この照明器具１０は、器具本体１と、光源ユニット２と、電源装置３と、非常用電源４と、カバー５とを備える。なお、器具本体１、電源装置３、非常用電源４及びカバー５については、図２で説明した照明器具１０と同様であるから、ここでは説明を省略する。   FIG. 5 is an exploded perspective view of another lighting fixture 10 of the present embodiment. The lighting fixture 10 includes a fixture main body 1, a light source unit 2, a power supply device 3, an emergency power supply 4, and a cover 5. The appliance main body 1, the power supply device 3, the emergency power supply 4 and the cover 5 are the same as those of the lighting fixture 10 described in FIG.

光源ユニット２は、基板２１（図１参照）と、レンズ２２と、取付部材２３と、放熱部材２４と、放熱シート２５（図１参照）とを備える。ここに、本例の光源ユニット２は、図１で説明した光源ユニット２よりも光出力の大きいＬＥＤチップ２１０（図１参照）を採用しており、ＬＥＤチップ２１０で発生する熱も大きくなる。従って、本例では、放熱部材２４による放熱効率を向上させるために、放熱部材２４の表面積を大きくしている。以下、放熱部材２４について具体的に説明する。   The light source unit 2 includes a substrate 21 (see FIG. 1), a lens 22, a mounting member 23, a heat radiating member 24, and a heat radiating sheet 25 (see FIG. 1). Here, the light source unit 2 of the present example employs the LED chip 210 (see FIG. 1) having a larger light output than the light source unit 2 described in FIG. 1, and the heat generated by the LED chip 210 is also increased. Therefore, in this example, the surface area of the heat dissipation member 24 is increased in order to improve the heat dissipation efficiency of the heat dissipation member 24. Hereinafter, the heat dissipation member 24 will be specifically described.

放熱部材２４は、図５に示すように、矩形板状の底壁部２４１と、底壁部２４１の端部より底壁部２４１と直交する方向（下向き）に突出する４つの側壁部２４２，２４４，２４６，２４７とで下面が開口する箱形に形成されている。側壁部２４２の下端には、外向き且つ底壁部２４１と平行に延出する延出部２４３が一体に設けられ、側壁部２４４の下端には、外向き且つ底壁部２４１と平行に延出する延出部２４５が一体に設けられている。   As shown in FIG. 5, the heat radiating member 24 includes a rectangular plate-like bottom wall portion 241 and four side wall portions 242 projecting in a direction (downward) perpendicular to the bottom wall portion 241 from the end of the bottom wall portion 241. 244, 246 and 247 are formed in a box shape whose lower surface is open.

Further, the side wall portion 244 is provided with a rectangular hooking hole 2441 that is hooked on a hooking claw (not shown) of the hooking portion 311 provided in the case 31 of the power supply device 3.

本例においても、ＬＥＤチップ２１０から放射される光の配光を変更する際には、レンズ２２を交換するだけでよく、従来例のようにランプ装置全体を交換しなくてもいいことから、コストアップを抑えることができる。   Also in this example, when changing the light distribution of the light emitted from the LED chip 210, it is only necessary to replace the lens 22, and it is not necessary to replace the entire lamp device as in the conventional example. Cost increase can be suppressed.

図６は本実施形態のさらに別の照明器具１０の分解斜視図である。上述の図２及び図５で説明した照明器具１０のように天井埋込型の照明器具だけでなく、本例の照明器具１０のように天井直付け型の照明器具であってもよい。この照明器具１０は、器具本体８と、光源ユニット２と、電源装置３と、非常用電源４と、カバー９とを備える。なお、光源ユニット２、電源装置３及び非常用電源４については、図２で説明した照明器具１０と同様であるから、ここでは説明を省略する。   FIG. 6 is an exploded perspective view of still another lighting fixture 10 of the present embodiment. The lighting fixture 10 described in FIGS. 2 and 5 described above is not limited to a ceiling-embedded lighting fixture, but may be a ceiling-mounted lighting fixture such as the lighting fixture 10 of this example. The lighting fixture 10 includes a fixture body 8, a light source unit 2, a power supply device 3, an emergency power supply 4, and a cover 9.

Through the opening 811, a power line (not shown) wired in advance on the back of the ceiling is passed. In addition, a suspension bolt (not shown) exposed from the ceiling plate is passed through the set of two through holes 812 and 812 and the dharma hole 813, respectively, to fix the instrument body 8 to the ceiling plate.

カバー９は、上面が開口し且つ上下方向を軸方向とする円筒状に形成された本体部９１を有し、本体部９１の底壁部には、円形の開口部９１１と楕円形状の開口部９１２とが設けられている。   The cover 9 has a main body portion 91 formed in a cylindrical shape having an upper surface opened and an axial direction in the vertical direction. A circular opening portion 911 and an elliptical opening portion are formed on the bottom wall portion of the main body portion 91. 912 are provided.

次に、この照明器具１０の施工手順について説明する。   Next, the construction procedure of this lighting fixture 10 will be described.

まず最初に、作業者は、器具本体８の開口部８１１を通して上記電源線を下向きに引き出した後、天井板から露出する吊ボルトを貫通孔８１２，ダルマ孔８１３に通して器具本体８を天井板に固定する。続けて、作業者は、電源装置３と非常用電源４とを組み付けた後、適宜の取付方法により電源装置３及び非常用電源４を器具本体８に取り付ける。   First, the operator pulls the power supply line downward through the opening 811 of the instrument body 8 and then passes the suspension bolt exposed from the ceiling plate through the through hole 812 and the dharma hole 813 to place the instrument body 8 in the ceiling plate. Secure to. Subsequently, after assembling the power supply device 3 and the emergency power supply 4, the worker attaches the power supply device 3 and the emergency power supply 4 to the instrument body 8 by an appropriate attachment method.

さらに、作業者は、電源装置３と非常用電源４とを組み付けることで形成される収納部１００に光源ユニット２を収納する。このとき、放熱部材２４の側壁部２４４に設けられた引掛孔２４４１に電源装置３のケース３１に設けられた引掛部３１１の引掛爪３１１１が引っ掛けられる。またこのとき、放熱部材２４の側壁部２４２に設けられた引掛孔（図示せず）に非常用電源４のケース４１に設けられた引掛部４１１の引掛爪４１１１が引っ掛けられる。その結果、光源ユニット２が電源装置３及び非常用電源４に保持される。   Further, the worker stores the light source unit 2 in the storage unit 100 formed by assembling the power supply device 3 and the emergency power supply 4. At this time, the hooking claw 3111 of the hooking part 311 provided in the case 31 of the power supply device 3 is hooked in the hooking hole 2441 provided in the side wall part 244 of the heat radiating member 24.

As a result, the light source unit 2 is held by the power supply device 3 and the emergency power supply 4.

そして最後に、作業者が、光源ユニット２、電源装置３及び非常用電源４を覆うようにカバー９を器具本体８に取り付けることで、照明器具１０の施工が完了する。   Finally, the worker attaches the cover 9 to the fixture main body 8 so as to cover the light source unit 2, the power supply device 3, and the emergency power supply 4, thereby completing the construction of the lighting fixture 10.

本例においても、ＬＥＤチップ２１０から放射される光の配光を変更する際には、レンズ２２を交換するだけでよく、従来例のようにランプ装置全体を交換しなくてもいいことから、コストアップを抑えることができる。   Also in this example, when changing the light distribution of the light emitted from the LED chip 210, it is only necessary to replace the lens 22, and it is not necessary to replace the entire lamp device as in the conventional example. Cost increase can be suppressed.

なお、本実施形態では、発光素子としてＬＥＤチップ２１０を例に説明したが、発光素子はＬＥＤチップ２１０に限らず、例えば有機ＥＬやレーザ・ダイオードなどであってもよい。また、接続部についてもコネクタ部２３２に限らず、基板２１と電源装置３との間を接続できれば他の構成でもよい。   In this embodiment, the LED chip 210 is described as an example of the light emitting element.
