以下、図面を参照して本発明の実施形態を詳細に説明する。本実施形態は、図１〜図３に示すように２つの光源１を支持して取付面(壁面Ｗ)に取り付けられる長尺の器具本体３、器具本体３に取り付けられて光源１を覆うカバー２、光源１を点灯させる点灯装置６などを備える。なお、以下の説明では、図１における上下方向を上下方向、図１における右向き(壁面Ｗから離れる向き)を前向き、左向き(壁面Ｗに近付く向き)を後向きとし、さらに図１の紙面に垂直な方向を左右方向と定義する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In this embodiment, as shown in FIGS. 1 to 3, a long instrument body 3 that supports two light sources 1 and is attached to an attachment surface (wall surface W), a cover that is attached to the instrument body 3 and covers the light source 1. 2. A lighting device 6 for turning on the light source 1 is provided. In the following description, the vertical direction in FIG. 1 is the vertical direction, the right direction (the direction away from the wall surface W) in FIG. The direction is defined as the left-right direction.

光源１は、図３に示すように３つの発光部10と、３つの発光部10を覆う透光パネル11と、一対のパネルエンド12とを有する。発光部10は、複数個の発光ダイオード(図示せず)、これら複数個の発光ダイオードが実装される実装基板100などを有する。実装基板100は、絶縁材料(例えば、セラミック)によって長尺の板状に形成されている。そして、複数個の発光ダイオードが実装基板100の一面側に長手方向(左右方向)に沿って直線状に並べて実装され、透光性を有し且つ蛍光材料が混合された合成樹脂製の封止部材101で発光ダイオードが封止されている。また、実装基板100に実装されている複数個の発光ダイオードは導電パターン(図示せず)によって直列に接続されている。そして、発光部10が発光(点灯)すると、発光ダイオードから放射される光(例えば、青色光)の一部が蛍光材料で波長変換され、波長変換された光(例えば、黄色光)と波長変換されなかった光(青色光)が混ざることで発光部10から放射される光が全体として白色光となる。   As shown in FIG. 3, the light source 1 includes three light emitting units 10, a translucent panel 11 that covers the three light emitting units 10, and a pair of panel ends 12. The light emitting unit 10 includes a plurality of light emitting diodes (not shown), a mounting substrate 100 on which the plurality of light emitting diodes are mounted, and the like. The mounting substrate 100 is formed in a long plate shape by an insulating material (for example, ceramic). A plurality of light emitting diodes are mounted on one surface side of the mounting substrate 100 in a straight line along the longitudinal direction (left and right direction), and are sealed with a synthetic resin mixed with a fluorescent material having translucency. The light emitting diode is sealed with the member 101. The plurality of light emitting diodes mounted on the mounting substrate 100 are connected in series by a conductive pattern (not shown). When the light emitting unit 10 emits light (lights up), a part of light emitted from the light emitting diode (for example, blue light) is wavelength-converted with a fluorescent material, and wavelength-converted light (for example, yellow light) and wavelength conversion are performed. The light emitted from the light emitting unit 10 becomes white light as a whole by mixing the light (blue light) that has not been performed.

透光パネル11は、図５に示すようにアクリル樹脂などの透光性を有する合成樹脂材料によって長尺の半円筒形状に形成され、長手方向の両端にそれぞれパネルエンド12が装着されている。パネルエンド12は、透光パネル11の端部を塞ぐ半円板状のエンド部12Aと、エンド部12Aの直線状の端縁より透光パネル11の長手方向に沿って突出する矩形平板状の固定部12Bとが透光パネル11と同じ透光性材料で一体に形成されている。なお、固定部12Bに貫通するねじ挿通孔(図示せず)に、透光パネル11を器具本体３に固定するための固定ねじ13が挿通される。   As shown in FIG. 5, the translucent panel 11 is formed in a long semi-cylindrical shape by a synthetic resin material having translucency such as acrylic resin, and panel ends 12 are attached to both ends in the longitudinal direction. The panel end 12 is a semi-disc-shaped end portion 12A that closes the end portion of the light transmissive panel 11, and a rectangular flat plate shape that protrudes along the longitudinal direction of the light transmissive panel 11 from the straight edge of the end portion 12A. The fixing portion 12B is integrally formed of the same translucent material as that of the translucent panel 11. A fixing screw 13 for fixing the translucent panel 11 to the instrument body 3 is inserted through a screw insertion hole (not shown) that penetrates the fixing portion 12B.

器具本体３は、図１及び図３，図４に示すようにそれぞれが光源１を保持する一対の光源保持部30，31、連結部32、カバー２を支持する３つの支持部33〜35などがアルミの押出成形によって一体に形成されてなる。一対の光源保持部30，31は長尺の板状であって、それぞれの前端同士が突き合わされた状態で結合されている。また、光源保持部30，31の後端は略平板状の連結部32によって連結されている。すなわち、一対の光源保持部30，31と連結部32とで内部が空洞の三角柱が形成されている。なお、以下の説明では、壁面Ｗに取り付けられたときに上に位置する方を上側光源保持部30と呼び、下に位置する方を下側光源保持部31と呼ぶことにする。   As shown in FIGS. 1, 3, and 4, the instrument body 3 includes a pair of light source holding portions 30 and 31 that hold the light source 1, a connecting portion 32, and three support portions 33 to 35 that support the cover 2. Are integrally formed by extrusion of aluminum. The pair of light source holding portions 30 and 31 are long plate-shaped, and are coupled in a state where their front ends are abutted with each other. The rear ends of the light source holding portions 30 and 31 are connected by a substantially flat connecting portion 32. That is, the pair of light source holding portions 30 and 31 and the connecting portion 32 form a triangular prism with a hollow inside. In the following description, the upper side when attached to the wall surface W will be referred to as the upper light source holding unit 30, and the lower side will be referred to as the lower light source holding unit 31.

上側光源保持部30と下側光源保持部31の前端から前方に、長手方向に沿って延びる略平板状の第１支持部33が突設されている。この第１保持部33の先端(前端)には円柱状の当接部33Aが一体に設けられている。また、上側光源保持部30の後端から後方且つ上方に、長手方向に沿って延びる略平板状の第２支持部34が突設されている。同じく、下側光源保持部31の後端から後方且つ下方に、長手方向に沿って延びる略平板状の第３支持部35が突設されている。なお、第２支持部34及び第３支持部35の先端は曲面形状に形成されている。第２支持部34及び第３支持部35の後面には、長手方向(左右方向)に沿った凹溝34A，35Aがそれぞれ形成されている。また、凹溝34A，35Aにはそれぞれ複数本(望ましくは３本以上)のボルト36が長手方向に沿ってほぼ等間隔に埋設されている(図１参照)。   A substantially flat plate-like first support portion 33 extending in the longitudinal direction is projected from the front ends of the upper light source holding portion 30 and the lower light source holding portion 31 in a projecting manner. A columnar contact portion 33A is integrally provided at the tip (front end) of the first holding portion 33. Further, a substantially flat plate-like second support portion 34 is provided so as to protrude rearward and upward from the rear end of the upper light source holding portion 30 along the longitudinal direction. Similarly, a substantially flat third support portion 35 extending in the longitudinal direction protrudes rearward and downward from the rear end of the lower light source holding portion 31. The tips of the second support part 34 and the third support part 35 are formed in a curved shape. On the rear surfaces of the second support portion 34 and the third support portion 35, concave grooves 34A and 35A are formed along the longitudinal direction (left-right direction), respectively. In addition, a plurality of (preferably three or more) bolts 36 are embedded in the concave grooves 34A and 35A, respectively, at substantially equal intervals along the longitudinal direction (see FIG. 1).

ところで、上側光源保持部30の保持面(上面)が第１支持部33の上面及び第２支持部34の前面から下方に後退している。同じく、下側光源保持部31の保持面(下面)が第１支持部33の下面及び第３支持部35の前面から上方に後退している。すなわち、器具本体３は、光源１を保持する部位に凹所が設けられ、凹所の底面(光源保持部30，31)に実装基板100が固定されることになる。   By the way, the holding surface (upper surface) of the upper light source holding unit 30 is retracted downward from the upper surface of the first support unit 33 and the front surface of the second support unit 34. Similarly, the holding surface (lower surface) of the lower light source holding unit 31 is retreated upward from the lower surface of the first support unit 33 and the front surface of the third support unit 35. That is, the instrument body 3 is provided with a recess in a portion that holds the light source 1, and the mounting substrate 100 is fixed to the bottom surface (the light source holding portions 30 and 31) of the recess.

ここで、実装基板100は、図３(ａ)に示すように器具本体３にねじ止めされた複数(図示例では９つ)の止め具14によって各光源保持部30，31に固定されている。また、固定部12Bのねじ挿通孔に挿通された固定ねじ13が、各光源保持部30，31の長手方向の両端部に設けられているねじ孔(図示せず)に螺合することで透光パネル11及びパネルエンド12が各光源保持部30，31に取り付けられる(図１及び図３参照)。   Here, the mounting substrate 100 is fixed to the light source holding portions 30 and 31 by a plurality (9 in the illustrated example) of fasteners 14 screwed to the instrument body 3 as shown in FIG. . Further, the fixing screws 13 inserted through the screw insertion holes of the fixing portion 12B are screwed into screw holes (not shown) provided at both ends in the longitudinal direction of the light source holding portions 30 and 31, respectively. The light panel 11 and the panel end 12 are attached to the light source holding portions 30 and 31 (see FIGS. 1 and 3).

カバー２は、透光性材料によって可撓性を有するシート状に形成されるものであって、例えば、ガラス繊維の織物、いわゆる、ガラスクロス(glass cloth)からなる。このようにカバー２を形成する材料としてガラスクロスを用いているため、グレアやランプイメージ(光源１の輪郭がカバー２越しに見えること)を低減し、やわらかい光による快適な照明環境を得ることができる。ただし、カバー２を形成する材料はガラスクロスに限定されるものではなく、透光性及び可撓性を有するシート状の材料であればよく、さらに不燃性であることが好ましい。   The cover 2 is formed into a flexible sheet shape by a translucent material, and is made of, for example, a glass fiber fabric, so-called glass cloth. Since glass cloth is used as a material for forming the cover 2 in this way, glare and lamp images (the contour of the light source 1 can be seen through the cover 2) can be reduced, and a comfortable lighting environment with soft light can be obtained. it can. However, the material for forming the cover 2 is not limited to glass cloth, and may be any sheet-like material having translucency and flexibility, and is preferably nonflammable.

次に、器具本体３に対するカバー２の取付方法について詳しく説明する。器具本体３の前方からカバー２が被せられ、第１支持部33先端の当接部33Aと、第２支持部34の先端部及び第３支持部35の先端部との間にカバー２が張り渡され、一方の端部が第２支持部34の凹溝34A内に挿入され、他方の端部が第３支持部35の凹溝35A内に挿入される。カバー２の両端部にはそれぞれ複数のねじ挿通孔(図示せず)が設けられており、各凹溝34A，35Aの底面から突出する複数本のボルト36が各ねじ挿通孔に挿通されることで器具本体３にカバー２が取り付けられる。   Next, the attachment method of the cover 2 with respect to the instrument main body 3 is demonstrated in detail. The cover 2 is covered from the front of the instrument body 3, and the cover 2 is stretched between the contact portion 33 </ b> A at the tip of the first support portion 33, the tip portion of the second support portion 34, and the tip portion of the third support portion 35. One end portion is inserted into the groove 34A of the second support portion 34, and the other end portion is inserted into the groove 35A of the third support portion 35. A plurality of screw insertion holes (not shown) are provided at both ends of the cover 2, and a plurality of bolts 36 protruding from the bottom surfaces of the concave grooves 34A and 35A are inserted into the screw insertion holes. Then, the cover 2 is attached to the instrument body 3.

ここで、器具本体３に取り付けられた状態のカバー２には常にテンションが掛かっているので、ねじ挿通孔の周辺部分が経時変化により延びてカバー２に弛みが生じる可能性がある。そのために本実施形態では、凹溝34A，35A内においてカバー２の端部を押さえる押さえ金具７を備えている。押さえ金具７は、金属板が曲げ加工されることで半角筒状に形成されるとともにボルト36が挿通される挿通孔(図示せず)が貫設され、両端部を底面に向けるようにして凹溝34A，35A内に収納される。そして、後述するようにボルト36にナットが螺合されると、押さえ金具７の両端と凹溝34A，35A底面との間にカバー２の端部がそれぞれ挟み込まれるため、カバー２の弛みを抑制することができる。   Here, since tension is always applied to the cover 2 attached to the instrument body 3, there is a possibility that the peripheral portion of the screw insertion hole extends due to a change with time and the cover 2 is slackened. For this purpose, in the present embodiment, a holding metal fitting 7 that holds the end of the cover 2 in the concave grooves 34A and 35A is provided. The presser fitting 7 is formed in a half-pipe cylinder shape by bending a metal plate, and has insertion holes (not shown) through which the bolts 36 are inserted, and is recessed so that both ends are directed to the bottom surface. It is stored in the grooves 34A and 35A. Then, as will be described later, when the nut is screwed onto the bolt 36, the end of the cover 2 is sandwiched between both ends of the presser fitting 7 and the bottom surfaces of the concave grooves 34A and 35A, thereby suppressing the looseness of the cover 2. can do.

なお、カバー２が取り付けられた器具本体３の長手方向(左右方向)の両端に、それぞれエンドキャップ５が取り付けられる。エンドキャップ５は、カバー２及び器具本体３の外形と同形状の略矢印形に形成された合成樹脂成形体からなる。各エンドキャップ５は、左右方向に突設されている一対の係止片50，51が第１支持部33及び連結部32にそれぞれ設けられた係止孔33B，32Aに係止されることで器具本体３に固定され(図４(ｂ)参照)、カバー２と器具本体３とで形成される内部空間の両端を塞いでいる。   End caps 5 are attached to both ends in the longitudinal direction (left-right direction) of the instrument body 3 to which the cover 2 is attached. The end cap 5 is made of a synthetic resin molded body formed in a substantially arrow shape having the same shape as the outer shape of the cover 2 and the instrument body 3. Each end cap 5 is configured such that a pair of locking pieces 50 and 51 projecting in the left-right direction are locked in locking holes 33B and 32A provided in the first support portion 33 and the connecting portion 32, respectively. It is fixed to the instrument body 3 (see FIG. 4B) and closes both ends of the internal space formed by the cover 2 and the instrument body 3.

点灯装置６は、従来周知の整流器やDC/DCコンバータなどで構成され、商用電源から供給される交流電力を直流電力に変換して発光部10を発光させる(光源１を点灯させる)ものである。本実施形態においては、図６に示すように一方の点灯装置６に、上側の光源１の３つの発光部10と下側の光源１の中央の発光部10が直列に接続され、他方の点灯装置６に、下側の光源１の左右両端の２つの発光部10が直列に接続されている。つまり、上側の光源１の３つの発光部10及び下側の光源１の中央の発光部10と、下側の光源１の左右両端の２つの発光部10とが２つの点灯装置６によって個別に点灯されることになる。   The lighting device 6 is configured by a conventionally known rectifier, DC / DC converter, or the like, and converts AC power supplied from a commercial power source into DC power to cause the light emitting unit 10 to emit light (lights the light source 1). . In the present embodiment, as shown in FIG. 6, one lighting device 6 is connected in series with the three light emitting units 10 of the upper light source 1 and the central light emitting unit 10 of the lower light source 1, and the other lighting device. Two light emitting units 10 at both left and right ends of the lower light source 1 are connected to the apparatus 6 in series. That is, the three light emitting units 10 of the upper light source 1 and the central light emitting unit 10 of the lower light source 1 and the two light emitting units 10 at the left and right ends of the lower light source 1 are individually provided by the two lighting devices 6. Will be lit.

点灯装置６は、図１に示すように整流器やDC/DCコンバータなどが金属製のケースに収納されてなり、器具本体３を壁面Ｗに取り付けるための取付台４の内部に収納される。取付台４は、鋼板などが曲げ加工されることで長尺の箱状に形成された本体部40と、鋼板などが曲げ加工されることで長尺の角樋状に形成され、本体部40の前面側に被せられるカバー部41とを有する(図１及び図３参照)。本体部40は、底面を壁面Ｗに当接するようにして壁面Ｗにねじ止めされ、その内底面に２つの点灯装置６が長手方向に並べて取り付けられる。カバー部41は、底面を本体部40の底面と対向させるようにして本体部40に被せられ、上下両側で本体部40にねじ止めされる。ここで、カバー部41の底部は、器具本体３の第２支持部34及び第３支持部35の後面に沿うように山型に形成されるとともに複数のねじ挿通孔が貫通されている。そして、カバー２及び押さえ金具７を第２支持部34と第３支持部35に固定している複数のボルト36がカバー部41の複数のねじ挿通孔に挿通され、カバー部41の内底面側に突出するボルト36にナットが締め付けられることで取付台４に器具本体３が固定される。   As shown in FIG. 1, the lighting device 6 includes a rectifier, a DC / DC converter, and the like housed in a metal case, and is housed in a mounting base 4 for attaching the fixture body 3 to the wall surface W. The mounting base 4 is formed into a long box shape by bending a steel plate or the like, and is formed into a long square hook shape by bending the steel plate or the like. And a cover portion 41 that covers the front side of the cover (see FIGS. 1 and 3). The main body 40 is screwed to the wall surface W so that the bottom surface is in contact with the wall surface W, and two lighting devices 6 are attached to the inner bottom surface side by side in the longitudinal direction. The cover part 41 is covered with the main body part 40 so that the bottom surface faces the bottom surface of the main body part 40, and is screwed to the main body part 40 on both upper and lower sides. Here, the bottom portion of the cover portion 41 is formed in a mountain shape so as to follow the rear surfaces of the second support portion 34 and the third support portion 35 of the instrument body 3, and a plurality of screw insertion holes are penetrated therethrough. Then, a plurality of bolts 36 fixing the cover 2 and the presser fitting 7 to the second support portion 34 and the third support portion 35 are inserted into the plurality of screw insertion holes of the cover portion 41, and the inner bottom surface side of the cover portion 41 The instrument main body 3 is fixed to the mounting base 4 by tightening the nuts to the bolts 36 projecting to.

本実施形態は、例えば、病室や宿泊施設の客室などの壁面に設置され、全ての光源１が点灯することで室内全体を照明することができる。また、本実施形態の下側の光源１が有する３つの発光部10のうちの両端の発光部10のみを点灯させれば、ベッドの枕元周辺を左右両側から照明することで読書灯の機能を実現することができる。   The present embodiment is installed on a wall surface of a guest room or a guest room of an accommodation facility, for example, and can illuminate the entire room by turning on all the light sources 1. In addition, if only the light emitting units 10 at both ends of the three light emitting units 10 included in the lower light source 1 of the present embodiment are turned on, the function of the reading lamp can be achieved by illuminating the bedside area from both the left and right sides. Can be realized.

上述のように本実施形態は、光源１を覆うカバー２が透光性材料によって可撓性を有するシート状に形成されているので、従来例の合成樹脂製のカバーに比較して軽量化が図れ、その結果、カバー２の垂れ下がりを抑えることができる。   As described above, in the present embodiment, the cover 2 that covers the light source 1 is formed into a flexible sheet shape by a translucent material, so that the weight can be reduced as compared with the synthetic resin cover of the conventional example. As a result, the drooping of the cover 2 can be suppressed.

また、本実施形態では、第１支持部33が器具本体３の長手方向に沿って延びる板状であって先端部でカバー２に当接してなり、カバー２に覆われた空間が第１支持部33によって上下２つの領域に分割され、各領域にそれぞれ光源１が配設されている。故に、上側の光源１から放射される光が第１支持部33に遮られて下方に行かず、同じく下側の光源１から放射される光が第１支持部33に遮られて上方に行かない。このため、室内を効率的に照明することができ、且つ外観上の見栄えがよく、上下切り替え可能な照明環境を提供することができる。なお、本実施形態では光源１が半円筒形であるので、直管形の蛍光ランプや直管形のＬＥＤランプを上下２段に備える構成と比較して、照明器具全体の高さ寸法が小型化できるという利点がある。また、パネルエンド12は、透光パネル11と同じ透光性材料で形成されているので、カバー２のエンドキャップ５付近まで暗がりになる箇所が生じない。   Moreover, in this embodiment, the 1st support part 33 is plate shape extended along the longitudinal direction of the instrument main body 3, Comprising: It contact | abuts on the cover 2 in the front-end | tip part, and the space covered with the cover 2 is the 1st support. The area 33 is divided into two upper and lower areas by the section 33, and the light source 1 is disposed in each area. Therefore, the light emitted from the upper light source 1 is blocked by the first support portion 33 and does not go downward, and the light emitted from the lower light source 1 is also blocked by the first support portion 33 and goes upward. Absent. For this reason, it is possible to efficiently illuminate the interior of the room, and to provide an illumination environment that has a good appearance and can be switched up and down. In this embodiment, since the light source 1 has a semi-cylindrical shape, the overall height of the lighting fixture is small as compared with a configuration in which a straight tube fluorescent lamp and a straight tube LED lamp are provided in two upper and lower stages. There is an advantage that can be made. Further, since the panel end 12 is formed of the same light-transmitting material as that of the light-transmitting panel 11, there is no darkened portion up to the vicinity of the end cap 5 of the cover 2.

さらに本実施形態は、器具本体３の光源１を保持する部位(光源保持部30，31)に凹所が設けられ、凹所の底面(光源保持部30，31)に実装基板100が固定されるため、凹所の深さ分だけ発光部10の位置を変位させることができる。このため、第１支持部33の上下両面及び第２支持部34及び第３支持部35の前面と発光部10の段差が小さくなり、第１支持部33の上下両面及び第２支持部34及び第３支持部35の前面における発光部10の近傍まで光が届くようになる。ここで、第１支持部33の上下両面及び第２支持部34及び第３支持部35の前面、すなわち、各支持部33〜35の光源１と対向する面が光源１から放射される光を反射する反射面であれば、照明空間に照射される光の均斉度を高めることができる。なお、前記面を反射面とするには、例えば、第１支持部33の上下両面及び第２支持部34及び第３支持部35の前面に白色の塗料が塗布されればよい。   Furthermore, in this embodiment, a recess is provided in a part (light source holding part 30, 31) that holds the light source 1 of the instrument body 3, and the mounting substrate 100 is fixed to the bottom surface (light source holding part 30, 31) of the recess. Therefore, the position of the light emitting unit 10 can be displaced by the depth of the recess. Accordingly, the upper and lower surfaces of the first support portion 33 and the steps of the second support portion 34 and the front surface of the third support portion 35 and the light emitting portion 10 are reduced, and the upper and lower surfaces of the first support portion 33 and the second support portion 34 and Light reaches the vicinity of the light emitting unit 10 on the front surface of the third support unit 35. Here, the light emitted from the light source 1 is emitted from the upper and lower surfaces of the first support portion 33 and the front surfaces of the second support portion 34 and the third support portion 35, that is, the surfaces of the support portions 33 to 35 facing the light source 1. If it is a reflective surface that reflects, the uniformity of the light irradiated to the illumination space can be increased. In order to make the surface a reflective surface, for example, white paint may be applied to the upper and lower surfaces of the first support portion 33 and the front surfaces of the second support portion 34 and the third support portion 35.
