An inverted T-shaped suspension rod 1 as shown in FIG. 2 is provided, and the surface constituting the upper wall of the storage portion 13 extends horizontally from the vertical support portion 11 to both sides, and the ceiling board 2 is supported. In addition, as shown in this figure, the method of supporting the ceiling board 2 may be such that the end of the ceiling board 2 is engaged and placed directly on the horizontal support portion 12, or a method other than this method may be used.

ここで、本実施形態の天井照明システムは、前記逆Ｔ字型吊持杆１の前記水平支持部１２の収納部１３内において前記開口の縁部に係合部４１を係合させ、かつ、前記開口から照明基板取付部４２を下方へ突出させる取付部材４を備えている。詳しくは、本実施形態の取付部材４は、図２に示すように、頭部４３の下面に垂設された軸部４４にねじが形成された前記照明基板取付部４２としてのボルト状部材４５と、前記軸部４４を挿通させる図示しない貫通孔が形成された係合部４１としての板状部材４６と、前記軸部４４に螺合するナット状部材４７から構成されている。なお、ボルト状部材４５の頭部４３を係合部４１として利用可能であれば、板状部材４６は省略することも可能である。 Here, the ceiling lighting system of the present embodiment has the engagement portion 41 engaged with the edge of the opening in the storage portion 13 of the horizontal support portion 12 of the inverted T-shaped suspension rod 1, and An attachment member 4 for projecting the illumination board attachment portion 42 downward from the opening is provided. Specifically, as shown in FIG. 2, the mounting member 4 of the present embodiment has a bolt-shaped member 45 as the illumination board mounting portion 42 in which a screw is formed on a shaft portion 44 that is suspended from the lower surface of the head 43. And a plate-like member 46 as an engaging portion 41 having a through hole (not shown) through which the shaft portion 44 is inserted, and a nut-like member 47 screwed into the shaft portion 44. If the head 43 of the bolt-shaped member 45 can be used as the engaging portion 41, the plate-shaped member 46 can be omitted.

また、本実施形態の天井照明システムは、薄板帯状とされ、１乃至複数個のＬＥＤ発光体３１が配置され、各ＬＥＤ発光体３１に対し通電可能に電線３３が配線された照明基板３２と、この照明基板３２の縁部に嵌着され、ＬＥＤ発光体３１を保護する乳白色の樹脂製のカバー３４とからなる照明器具３を備えている。詳しくは、本実施形態の照明基板３２は、複数個のＬＥＤ発光体３１が等間隔で長手方向に配列されているとともに、後述する、照明基板取付部４２としてのボルト状部材４５の前記軸部４４を挿通させる貫通孔３５が長手方向における中間部に複数穿設されている。なお、前記ＬＥＤ発光体３１の配設数や配設位置、前記貫通孔３５の配設数や配設位置は本実施形態の例に限定されるものではない。また、前記天井裏には、天井面に配設されるこの照明器具３に給電する電源等の電気経路が敷設されているものとする。 In addition, the ceiling lighting system of the present embodiment has a thin strip shape, one to a plurality of LED light emitters 31 are arranged, and an illumination board 32 on which an electric wire 33 is wired so as to be able to energize each LED light emitter 31; A lighting fixture 3 is provided, which is fitted to an edge of the lighting board 32 and includes a milky white resin cover 34 that protects the LED light emitter 31. Specifically, in the illumination board 32 of the present embodiment, the plurality of LED light emitters 31 are arranged in the longitudinal direction at equal intervals, and the shaft portion of the bolt-shaped member 45 as the illumination board mounting portion 42 described later. A plurality of through-holes 35 through which 44 is inserted are formed in an intermediate portion in the longitudinal direction. The number and positions of the LED light emitters 31 and the number and positions of the through holes 35 are not limited to the example of this embodiment. In addition, an electrical path such as a power source for supplying power to the lighting fixture 3 disposed on the ceiling surface is laid on the back of the ceiling.

さらに、本実施形態の天井照明システムにおいて、前記開口は水平支持部１２の長手方向にスリット形成されており、逆Ｔ字型吊持杆１を直交させて接続させた接続部位においては、前記スリットが連通するように構成されている（図１、図３参照）。そして、前記水平支持部１２には、後述するように、前記取付部材４の板状部材４６およびボルト状部材４５の頭部４３を前記収納部１３内に配置させるための取入口１４が形成されている。なお、吊持杆１を金属板を折り曲げて形成することにより、前記収納部１３の開口を簡単にスリット形成することができ、取入口１４を所望の場所に形成することが可能となる。 Furthermore, in the ceiling lighting system according to the present embodiment, the opening is formed as a slit in the longitudinal direction of the horizontal support portion 12, and the slit is formed at a connection portion where the inverted T-shaped suspension rod 1 is connected orthogonally. Are configured to communicate with each other (see FIGS. 1 and 3). The horizontal support portion 12 is formed with an inlet 14 for arranging the plate-like member 46 of the mounting member 4 and the head portion 43 of the bolt-like member 45 in the storage portion 13 as will be described later. ing. By forming the suspension rod 1 by bending a metal plate, the opening of the storage portion 13 can be easily formed into a slit, and the intake 14 can be formed at a desired location.

そして、本実施形態の天井照明システムにおいては、まず、板状部材４６の貫通孔に軸部４４を挿通させた状態で、前記板状部材４６と、ボルト状部材４５の頭部４３を取入口１４から前記収納部１３内に収納し、前記軸部４４を開口から下方へ突出させ、照明器具３を配設する逆Ｔ字型吊持杆１の水平支持部１２における前記照明器具３の照明基板３２の貫通孔３５と対向するそれぞれの位置へ、前記スリットに沿って移動させる。つまり、このとき、前記板状部材４６と、ボルト状部材４５の頭部４３をライナーとして用い、前記収納部１３内をスライド移動させる。 In the ceiling lighting system of the present embodiment, first, the plate-like member 46 and the head 43 of the bolt-like member 45 are taken in with the shaft portion 44 inserted through the through-hole of the plate-like member 46. 14 is housed in the housing portion 13, the shaft portion 44 protrudes downward from the opening, and the lighting fixture 3 is illuminated in the horizontal support portion 12 of the inverted T-shaped suspension rod 1 in which the lighting fixture 3 is disposed. The substrate 32 is moved along the slits to positions facing the through holes 35 of the substrate 32. That is, at this time, the plate-like member 46 and the head portion 43 of the bolt-like member 45 are used as a liner, and the inside of the storage portion 13 is slid.

そして、各位置において、貫通孔３５に前記照明基板取付部４２としてのボルト状部材４５の前記軸部４４を挿通させた状態で、ナット状部材４７を軸部４４に螺合させ、前記係合部４１としての板状部材４６とナット状部材４７との間に収納部１３の下面の前記開口の縁部と照明基板３２とを挟み込んだ状態で固定する。これにより、前記照明基板取付部４２に照明基板３２を取付ける。 Then, at each position, with the shaft portion 44 of the bolt-shaped member 45 serving as the illumination board mounting portion 42 inserted in the through hole 35, the nut-shaped member 47 is screwed into the shaft portion 44 and the engagement is performed. Between the plate-like member 46 and the nut-like member 47 as the portion 41, the edge portion of the opening on the lower surface of the storage portion 13 and the illumination board 32 are sandwiched and fixed. Thereby, the illumination board 32 is attached to the illumination board mounting portion 42.

なお、この照明器具３の取付の際に、前記照明基板３２と電源とを結ぶ配線は、逆Ｔ字型吊持杆１に形成された配線引き出し孔から天井裏へ引き出して電源と電気的な接続を確保するようにする。 When the lighting fixture 3 is attached, the wiring connecting the lighting board 32 and the power source is drawn out from the wiring lead hole formed in the inverted T-shaped suspension rod 1 to the back of the ceiling and electrically connected to the power source. Ensure connection.

そして、照明基板３２の縁部にＬＥＤ発光体３１を保護する乳白色の樹脂製のカバー３４を嵌着させる。 Then, a milky white resin cover 34 that protects the LED light emitter 31 is fitted to the edge of the illumination board 32.

図３は、照明器具３が十字状に配設される、天井ボード２のコーナーの配設例を示す。この樹脂製のカバー３４のように端部角部をそれぞれ９０°づつ面取りして三角形状に形成し、互いの先端部を付き合わせ、面取り形成された辺同士を並列させるように配設することで、互いのカバー３４が干渉することなく、見た目にも美しく照明器具３を配設することができる。 FIG. 3 shows an arrangement example of the corners of the ceiling board 2 in which the lighting fixtures 3 are arranged in a cross shape. Like the resin cover 34, the corners of the end portions are chamfered by 90 ° to form a triangular shape, the tips of each other are attached, and the chamfered sides are arranged side by side. Therefore, the lighting fixture 3 can be arranged beautifully without any interference between the covers 34.

なお、前記照明器具３の長さ寸法は任意である。また、逆Ｔ字型吊持杆１の組み込みは、本実施形態のように格子状に限らず、たとえば平行であってもよい。 In addition, the length dimension of the said lighting fixture 3 is arbitrary. Moreover, the incorporation of the inverted T-shaped suspension rod 1 is not limited to the lattice shape as in the present embodiment, and may be parallel, for example.

さらに、前記取付部材４は、前述のようなボルト状部材４５やナットを用いるものに限らない。例えば、前記係合部４１は、一対の係合爪が前記収納部１３内において前記開口の縁部に対し係合・係合解除可能に形成されていてもよいし、照明基板取付部４２も、ねじが形成された軸部４４に限ることなく、照明基板３２に形成された係合孔に嵌着して前記照明基板３２を吊下する爪状部材が先端に形成された軸状部材としてもよい。 Furthermore, the mounting member 4 is not limited to the one using the bolt-shaped member 45 or the nut as described above. For example, the engaging portion 41 may be formed such that a pair of engaging claws can be engaged and disengaged with respect to the edge portion of the opening in the storage portion 13. As a shaft-like member having a claw-like member that is fitted in an engagement hole formed in the illumination board 32 and suspends the illumination board 32 as a shaft-like member, not limited to the shaft portion 44 formed with a screw. Also good.

また、前記開口をスリット形成せずに、吊持杆１の長手方向に点在させる構成としてもよい。その場合、開口は、吊持杆１の長手方向の寸法を幅方向寸法の寸法より長く形成した長穴に形成するとともに、前記幅方向において、収納部１３の下面に係合部４１が係止する開口の縁部を形成し、例えば、長手方向に沿って前記開口から収納部１３内に挿入させた係合部４１を、水平方向に９０°回転させることにより、係合部４１の先端を開口の縁部に係合させる構成としてもよい。その係合部４１には前記照明基板取付部４２が連接されていることは勿論である。 Moreover, it is good also as a structure which is dotted with the longitudinal direction of the hanging rod 1 without forming the said opening slit. In that case, the opening is formed in a long hole in which the dimension in the longitudinal direction of the suspension rod 1 is longer than the dimension in the width direction, and the engagement portion 41 is locked to the lower surface of the storage portion 13 in the width direction. For example, by rotating the engaging portion 41 inserted into the housing portion 13 from the opening along the longitudinal direction by 90 ° in the horizontal direction, the tip of the engaging portion 41 is moved. It is good also as a structure engaged with the edge part of opening. Needless to say, the illumination board mounting portion 42 is connected to the engaging portion 41.

前記照明基板３２のＬＥＤ発光体３１の配設面は、ＬＥＤ発光体３１の出射光を反射させるリフレクタ面として形成してもよい。その際、照明基板３２のＬＥＤ発光体３１の配設面は平面である必要はなく、配設するＬＥＤ発光体３１毎に合わせた半球面の連続面、曲面、凹凸面等に変更することができる。 The surface of the illumination board 32 on which the LED light emitter 31 is disposed may be formed as a reflector surface that reflects the light emitted from the LED light emitter 31. At that time, the surface of the illumination substrate 32 on which the LED light emitter 31 is disposed need not be a flat surface, and may be changed to a hemispherical continuous surface, curved surface, uneven surface, or the like for each LED light emitter 31 to be disposed. it can.

さらには、前記吊持杆１は、逆Ｔ字型吊持杆１に限らず、例えば、前記垂直支持部１１の下部における一側方にのみその収納部１３の上壁を構成する面が水平に延出し、天井ボード２を支持するように構成されているＬ字型吊持杆１であっても、収納部１３を有する吊持杆１であれば、本発明の天井照明システムを採用することができる。 Further, the suspension rod 1 is not limited to the inverted T-shaped suspension rod 1. For example, the surface constituting the upper wall of the storage portion 13 is horizontal only on one side of the lower portion of the vertical support portion 11. Even if it is the L-shaped suspension rod 1 extended so that it may support the ceiling board 2, if it is the suspension rod 1 which has the accommodating part 13, the ceiling lighting system of this invention is employ | adopted. be able to.

そして、このように構成される本実施形態の天井照明システムにおいては、照明機具を配設する吊持杆１の形状を、照明器具３の形や配置によってその形状を異ならせる必要がないので、吊持杆１や天井ボード２の生産工程が繁雑になることがない。 And, in the ceiling lighting system of the present embodiment configured as described above, the shape of the hanging rod 1 for arranging the lighting device does not need to be changed depending on the shape and arrangement of the lighting fixture 3, The production process of the hanging rod 1 and the ceiling board 2 does not become complicated.

さらに、天井の形成作業における照明器具３の施工工事が一人の作業も可能となり、作業効率も大きく向上された。 Furthermore, the construction work of the lighting fixture 3 in the ceiling forming work can be performed by one person, and the work efficiency is greatly improved.

また、照明器具３の配設位置の変更が容易であるので、室内のレイアウト変更に制約を受けることがなくなり、施工工事も簡便になる等の優れた効果を奏する。 Moreover, since the change of the arrangement position of the lighting fixture 3 is easy, there is no restriction on the indoor layout change, and excellent effects such as simple construction work are obtained.
