電源装置6は、電源基板と、電源基板を収納する収納ケース60とを有する(図3参照)。電源基板は、左右方向に長い矩形板状に形成されたプリント配線板からなり、このプリント配線板には、少なくともLED30の点灯電力を生成するために必要な回路部品(例えば、トランスやダイオード、コンデンサなど)が実装されている。収納ケース60は、長手方向(左右方向)の両端が開口する矩形箱状に形成されている。また、収納ケース60は、例えば、ねじなどを用いて支持部材4(の底板40)の第2面(上面)に取り付けられることが好ましい。   The power supply device 6 includes a power supply board and a storage case 60 for storing the power supply board (see FIG. 3). The power supply board is formed of a printed wiring board formed in a rectangular plate shape that is long in the left-right direction. The printed wiring board includes at least circuit components (for example, a transformer, a diode, a capacitor, etc.) that are required to generate the lighting power of the LED 30. Etc.) has been implemented. The storage case 60 is formed in a rectangular box shape that is open at both ends in the longitudinal direction (left-right direction). Moreover, it is preferable that the storage case 60 is attached to the 2nd surface (upper surface) of the supporting member 4 (the bottom plate 40) using a screw etc., for example.

ケース5は、ケース本体50と2つのエンド部材51及び防水パッキン52で構成される(図2参照)。ケース本体50は、合成樹脂材料によって長手方向の両端が開口した長尺の筒状に形成され、その内部にLEDモジュール3及び支持部材4を収容するように構成されている(図1及び図2参照)。なお、支持部材4は、後述するように3つの固定具7によってケース本体50に固定される。   The case 5 includes a case main body 50, two end members 51, and a waterproof packing 52 (see FIG. 2). The case main body 50 is formed in a long cylindrical shape with both ends in the longitudinal direction opened by a synthetic resin material, and is configured to accommodate the LED module 3 and the support member 4 therein (FIGS. 1 and 2). reference).

(See FIG. 2). However, the connection part of a pair of side wall 501 and the front wall 502 is formed in the curved surface shape which protrudes outside (refer FIG. 1). Further, the pair of side walls 501 are curved outward so as to be separated from the rear wall 500 downward (see FIG. 1). Furthermore, the front wall 502 is formed in a semi-cylindrical shape that bulges downward from both ends toward the center. However, the case main body 50 is preferably formed by two-color extrusion molding of a synthetic resin material (such as acrylic resin or polycarbonate resin) having translucency and a synthetic resin material having no translucency. Here, a part formed of a synthetic resin material having translucency is referred to as a transmission part 503, and a part formed of a synthetic resin material having no translucency is referred to as a non-transmission part 504 (FIG. 1). reference). That is, the light emitted from the LED module 3 is subjected to light distribution control when passing through the transmission unit 503. Note that the transmissive portion 503 is preferably configured to diffuse light by mixing a diffusing material or forming a large number of irregularities.

エンド部材51は、図1〜図3に示すように、第1底壁510、第2底壁511、外周壁512、内周壁513並びにカバー部514を有する。第1底壁510は、厚み方向(左右方向)から見た外形が、ケース本体50を左右方向から見た外形と相似する形状に形成される。第2底壁511は、厚み方向(左右方向)から見た外形が、ケース本体50の透過部503を左右方向から見た外形と相似する形状(略半円形状)に形成される。外周壁512は、第1底壁510の周縁から全周に渡って突出する筒状に形成される。内周壁513は、外周壁512に対向して第1底壁510から突出する筒状に形成される。カバー部514は、第2底壁511の周縁の弧状の部分から第2底壁511の厚み方向に突出し、かつ、その表面を外周壁512の表面と同一の曲面(略半円筒面)とする形状に形成される(図2参照)。また、カバー部514の下面中央には、円筒形の凹部5140が設けられている(図2参照)。さらに、凹部5140の底壁には、円形の孔が形成されている。   As shown in FIGS. 1 to 3, the end member 51 includes a first bottom wall 510, a second bottom wall 511, an outer peripheral wall 512, an inner peripheral wall 513, and a cover portion 514. The first bottom wall 510 is formed in a shape similar to the outer shape of the case body 50 viewed from the left-right direction when viewed from the thickness direction (left-right direction). The second bottom wall 511 is formed in a shape (substantially semicircular shape) whose outer shape viewed from the thickness direction (left-right direction) is similar to the outer shape of the transmission part 503 of the case body 50 viewed from the left-right direction. The outer peripheral wall 512 is formed in a cylindrical shape that protrudes from the periphery of the first bottom wall 510 over the entire periphery. The inner peripheral wall 513 is formed in a cylindrical shape that protrudes from the first bottom wall 510 so as to face the outer peripheral wall 512. The cover part 514 protrudes in the thickness direction of the second bottom wall 511 from the arc-shaped portion of the peripheral edge of the second bottom wall 511, and the surface thereof is the same curved surface (substantially semi-cylindrical surface) as the surface of the outer peripheral wall 512. It is formed into a shape (see FIG. 2). A cylindrical recess 5140 is provided at the center of the lower surface of the cover portion 514 (see FIG. 2). Further, a circular hole is formed in the bottom wall of the recess 5140.

防水パッキン52は、シリコーン樹脂などの弾性を有する材料により、エンド部材51の外周壁512及び内周壁513に相似した形状(筒状)に形成されている。そして、防水パッキン52は、エンド部材51の第1底壁510と外周壁512と内周壁513に囲まれた空間に圧入される(図1参照)。さらに、防水パッキン52は、外周壁512及び内周壁513の先端から露出する面に全周に渡る溝520が設けられている。そして、この溝520にケース本体50の長手方向における端部が圧入される(図1参照)。つまり、エンド部材51とケース本体50の隙間が防水パッキン52によって密閉され、ケース本体50内への水(雨水など)の浸入が抑制される。   The waterproof packing 52 is formed in a shape (cylindrical shape) similar to the outer peripheral wall 512 and the inner peripheral wall 513 of the end member 51 by a material having elasticity such as silicone resin. The waterproof packing 52 is press-fitted into a space surrounded by the first bottom wall 510, the outer peripheral wall 512, and the inner peripheral wall 513 of the end member 51 (see FIG. 1). Further, the waterproof packing 52 is provided with a groove 520 over the entire circumference on the surface exposed from the tips of the outer peripheral wall 512 and the inner peripheral wall 513. And the edge part in the longitudinal direction of the case main body 50 is press-fit in this groove | channel 520 (refer FIG. 1). That is, the gap between the end member 51 and the case main body 50 is sealed by the waterproof packing 52, and the intrusion of water (rain water or the like) into the case main body 50 is suppressed.

In addition, it is preferable that these three fixing tools 7 are each attached to the both ends and center of the longitudinal direction (left-right direction) of the supporting member 4 (refer FIG. 3).

取付具8は、図1〜図3に示すように、第1固定部80と、第2固定部81と、第1固定部80と第2固定部81を連結する連結部82とが金属板を加工することで一体に形成される。第1固定部80は、平坦な矩形板状に形成され、前後方向の中央に円錐台状の突部800が設けられる。突部800の天面には、円形のねじ挿通孔が貫通している。連結部82は、前後方向から見てL形に曲げられている。第2固定部81は、矩形平板状であって、連結部82の下端から水平かつ外向きに突出するように構成される。第2固定部81は、長手方向(前後方向)のほぼ中央に長孔状のねじ挿通孔810が設けられている(図3参照)。   As shown in FIGS. 1 to 3, the fixture 8 includes a first fixing portion 80, a second fixing portion 81, and a connecting portion 82 that connects the first fixing portion 80 and the second fixing portion 81. Are integrally formed. The first fixed portion 80 is formed in a flat rectangular plate shape, and a truncated cone-shaped protrusion 800 is provided at the center in the front-rear direction. A circular screw insertion hole passes through the top surface of the protrusion 800. The connecting portion 82 is bent into an L shape when viewed from the front-rear direction. The second fixing portion 81 has a rectangular flat plate shape and is configured to protrude horizontally and outward from the lower end of the connecting portion 82. The second fixing portion 81 is provided with a long hole-like screw insertion hole 810 at substantially the center in the longitudinal direction (front-rear direction) (see FIG. 3).

次に、光源ユニット2の組立手順について説明する。まず、作業者は、LEDモジュール3や電源装置6、並びに3つの固定具7が取り付けられた支持部材4を、長手方向の一端側からケース本体50内に挿入して収容する。さらに、作業者は、支持部材4に取り付けられている3つの固定具7にケース本体50を固定する。すなわち、作業者は、ケース本体50の後壁500の長手方向の両端及び中央にそれぞれ設けられているねじ挿通孔に固定ねじ53をそれぞれ挿通し、各固定片70の一方のねじ孔700に固定ねじ53をねじ込む。   Next, the assembly procedure of the light source unit 2 will be described. First, an operator inserts and accommodates the support member 4 to which the LED module 3, the power supply device 6, and the three fixtures 7 are attached into the case main body 50 from one end side in the longitudinal direction. Further, the operator fixes the case main body 50 to the three fixtures 7 attached to the support member 4. That is, the operator inserts the fixing screws 53 into the screw insertion holes respectively provided at both ends and the center in the longitudinal direction of the rear wall 500 of the case main body 50, and is fixed to one screw hole 700 of each fixing piece 70. Screw in the screw 53.

続いて、作業者は、取付具8の第2固定部81のねじ挿通孔810に取付ねじ83を挿通した後、防水パッキン52を取り付けたエンド部材51をケース本体50の端部に被せる。そして、作業者は、エンド部材51の上に取付具8を被せた状態で、取付具8の第1固定部80のねじ挿通孔にねじを挿通し、このねじを、ケース本体50の後壁500に設けられる孔を通して、固定片70の他方のねじ孔700にねじ込む。つまり、取付具8が固定具7に固定(ねじ止め)されることにより、取付具8の連結部82によってエンド部材51と防水パッキン52が抜け止めされる(図3参照)。以上のようにして、光源ユニット2が組み立てられる。   Subsequently, the operator inserts the attachment screw 83 into the screw insertion hole 810 of the second fixing portion 81 of the fixture 8, and then covers the end member 51 to which the waterproof packing 52 is attached over the end portion of the case body 50. Then, the operator inserts a screw into the screw insertion hole of the first fixing portion 80 of the fixture 8 in a state where the fixture 8 is put on the end member 51, and this screw is inserted into the rear wall of the case body 50. The other screw hole 700 of the fixing piece 70 is screwed through the hole provided in 500. That is, when the fixture 8 is fixed (screwed) to the fixture 7, the end member 51 and the waterproof packing 52 are prevented from coming off by the connecting portion 82 of the fixture 8 (see FIG. 3). The light source unit 2 is assembled as described above.

次に、照明器具の施工手順について説明する。作業者は、器具本体1を天井に取り付けた後、光源ユニット2の上部(2つの取付具8の第2固定部81よりも上側の部分)を器具本体1の第1面(下面)の開口内に挿入する。そして、作業者は、エンド部材51のカバー部514の凹部5140にドライバの軸を挿入し、凹部5140の底壁に設けられている孔を通して、第2固定部81のねじ挿通孔810に挿通されている取付ねじ83を締め込む。その結果、取付ねじ83が、器具本体1の取付片132のねじ孔133にねじ込まれるので、取付具8の第2固定部81が器具本体1の取付片132にねじ止め(固定)される。最後に、作業者は、カバー部514の表面に露出している凹部5140の口をテープなどで塞いで目隠しすることが好ましい。このようにして、光源ユニット2が器具本体1に取り付けられることで照明器具の施工が完了する(図4A、図4B、図4C参照)。   Next, the construction procedure of the lighting fixture will be described. After attaching the instrument main body 1 to the ceiling, the operator opens the upper part of the light source unit 2 (the part above the second fixing part 81 of the two fixtures 8) on the first surface (lower surface) of the instrument main body 1. Insert inside. Then, the operator inserts the driver shaft into the recess 5140 of the cover portion 514 of the end member 51, and is inserted into the screw insertion hole 810 of the second fixing portion 81 through the hole provided in the bottom wall of the recess 5140. The mounting screw 83 is tightened. As a result, the attachment screw 83 is screwed into the screw hole 133 of the attachment piece 132 of the instrument body 1, so that the second fixing portion 81 of the attachment tool 8 is screwed (fixed) to the attachment piece 132 of the instrument body 1. Finally, it is preferable for the operator to cover the mouth of the concave portion 5140 exposed on the surface of the cover portion 514 with a tape or the like so as to be blindfolded. Thus, the installation of the lighting fixture is completed by attaching the light source unit 2 to the fixture body 1 (see FIGS. 4A, 4B, and 4C).

ここで、ケース本体50のうち、支持部材4の底板40の第1面(下面)と対向する部位(透過部503の大部分)を第1部位505とする。また、ケース本体50のうち、底板40の第2面(上面)と対向する部位(不透過部504)を第2部位506とする。さらに、ケース本体50のうち、第1部位505と第2部位506とを繋ぐ部位(透過部503の第1部位505以外の部分)を第3部位507とする(図1参照)。ケース本体50は、第1面及び第2面と平行な方向(前後方向)において、第1部位505及び第2部位506の幅寸法よりも第3部位507の幅寸法の方が大きくなるように構成される。   Here, a portion of the case main body 50 that faces the first surface (lower surface) of the bottom plate 40 of the support member 4 (most part of the transmission portion 503) is defined as a first portion 505. In addition, a portion of the case main body 50 that opposes the second surface (upper surface) of the bottom plate 40 (an impermeable portion 504) is referred to as a second portion 506. Furthermore, the part (part other than the 1st site | part 505 of the permeation | transmission part 503) which connects the 1st site | part 505 and the 2nd site | part 506 among the case main bodies 50 is made into the 3rd site | part 507 (refer FIG. 1). In the case body 50, the width dimension of the third part 507 is larger than the width dimension of the first part 505 and the second part 506 in the direction (front-rear direction) parallel to the first surface and the second surface. Composed.

LED30から放射される光の一部は、底板40の第1面に反射されてから第1部位505を通してケース本体50の外に出射される。また、LED30から放射される光の一部は、第1部位505の内周面に反射される。そして、第1部位505の内周面に反射された光の一部が、支持部材4の側板41と第3部位507との間の空間に進行し、直接又は側板41の表面に反射されて、第3部位507からケース本体50の外に出射される。つまり、LED30から放射された光が、側板41の先端(上端)よりも上方に進行する可能性は非常に低いと考えられる。したがって、側板41よりも上に存在する第2部位506を器具本体1内に収容し、かつ、第2部位506の幅寸法を第3部位よりも小さくすることにより、器具本体1の幅寸法(前後方向の長さ寸法)を相対的に小さくすることができる。   A part of the light emitted from the LED 30 is reflected by the first surface of the bottom plate 40 and then emitted out of the case body 50 through the first portion 505. A part of the light emitted from the LED 30 is reflected on the inner peripheral surface of the first portion 505. A part of the light reflected on the inner peripheral surface of the first part 505 travels to the space between the side plate 41 and the third part 507 of the support member 4 and is reflected directly or on the surface of the side plate 41. The light is emitted from the third portion 507 to the outside of the case body 50. That is, it is considered that the possibility that the light emitted from the LED 30 travels higher than the tip (upper end) of the side plate 41 is very low. Therefore, the second part 506 existing above the side plate 41 is accommodated in the instrument main body 1 and the width dimension of the second part 506 is made smaller than the third part, whereby the width dimension ( The length dimension in the front-rear direction) can be made relatively small.

さらに、器具本体1は、第1面(開口面、すなわち、下面)を囲む周縁の少なくとも一部分(第1側壁11A、11Bの下端)において、ケース5に近付く向きに突出する突片14をそれぞれ有している(図1及び図2参照)。各突片14は、第1側壁11A及び第2側壁12Aの下端において、長手方向の両端部を除くほぼ全体に渡って設けられている。つまり、光源ユニット2のケース本体50と、器具本体1の第1側壁11A、11Bの下端との間に隙間が生じるが、この隙間を、各突片14で覆い隠すことができる(図4A参照)。ゆえに、本実施形態に係る照明器具では、器具本体1の小型化を図ることができるとともに、器具本体1と光源ユニット2との境界部分の明るさ(輝度)の低下を抑制することができる。   Furthermore, the instrument main body 1 has protrusions 14 that protrude in a direction approaching the case 5 at least at a part of the periphery (the lower ends of the first side walls 11A and 11B) surrounding the first surface (opening surface, that is, the lower surface). (See FIGS. 1 and 2). Each projecting piece 14 is provided over substantially the whole of the lower end of the first side wall 11A and the second side wall 12A except for both ends in the longitudinal direction. That is, a gap is generated between the case main body 50 of the light source unit 2 and the lower ends of the first side walls 11A and 11B of the instrument main body 1, and this gap can be covered with the projecting pieces 14 (see FIG. 4A). ). Therefore, in the lighting fixture according to the present embodiment, the fixture main body 1 can be reduced in size, and a decrease in brightness (luminance) at the boundary between the fixture main body 1 and the light source unit 2 can be suppressed.

上述のように本実施形態に係る照明器具は、光源ユニット2と、器具本体1とを備える。光源ユニット2は、LEDモジュール3と、LEDモジュール3を支持する支持部材4と、LEDモジュール3及び支持部材4を内部に収容するケース5とを備える。支持部材4は、第1面(下面)にLEDモジュール3が取り付けられる底板40を有する。ケース5は、底板40の第1面(下面)と対向する第1部位505と、底板40の第1面と反対側の第2面(上面)と対向する第2部位506と、第1部位505と第2部位506とを繋ぐ第3部位507とを有する。ケース5は、第1面及び第2面と平行な方向において、第1部位505及び第2部位506の幅寸法よりも第3部位507の幅寸法の方が大きくなるように構成される。器具本体1は、第1面(下面)が開口する箱状に形成される。器具本体1は、ケース5の第2部位506の全部又は一部を第1面から内部に挿入した状態で光源ユニット2を保持するように構成される。さらに、器具本体1は、第1面を囲む周縁の少なくとも一部分(第1側壁11A、11Bの下端)において、ケース5に近付く向きに突出する突片14を有する。   As described above, the lighting fixture according to the present embodiment includes the light source unit 2 and the fixture main body 1.
