（実施形態）
図１は、本発明の実施形態の照明器具１の分解斜視図である。同図に示すように、実施形態の照明器具１は、本体１０、光拡散カバー３０、光源５０及びカバー部材６０から構成されており、本体１０に配置された取付具９０により、光拡散カバー３０、光源５０及びカバー部材６０が一体的に設置される。なお、図面において、配線、ネジ等の構成要素は省略している（以下、同じ）。 (Embodiment)
FIG. 1 is an exploded perspective view of the lighting fixture 1 according to the embodiment of the present invention. As shown in the figure, the lighting fixture 1 of the embodiment is composed of a main body 10, a light diffusion cover 30, a light source 50, and a cover member 60, and the light diffusion cover 30 is provided by a fixture 90 arranged on the main body 10. , The light source 50 and the cover member 60 are integrally installed. In the drawings, components such as wiring and screws are omitted (hereinafter the same).

本体１０は、別称「シャーシ」ともいわれる部材であり、冷間圧延鋼板等の金属材料の平板から円形状に成形され、中央に、円形の開口１３が形成されている。本体１０の開口１３には、照明器具１を天井２に配置された配線器具３に取り付けるためのアダプタ８０が取り付けられる（図６参照）。アダプタ８０を挿通するため、本体１０の開口１３は本体１０、光源５０、光拡散カバー３０の中央にも共通して設けられている。 The main body 10 is a member also known as a “chassis”, which is formed into a circular shape from a flat plate of a metal material such as a cold-rolled steel plate, and has a circular opening 13 formed in the center. An adapter 80 for attaching the lighting fixture 1 to the wiring fixture 3 arranged on the ceiling 2 is attached to the opening 13 of the main body 10 (see FIG. 6). In order to insert the adapter 80, the opening 13 of the main body 10 is also provided in common in the center of the main body 10, the light source 50, and the light diffusion cover 30.

光源５０は、中央に略円形の開口１３が形成された略四角形の基板５１上にＬＥＤ等の複数の発光素子５２が実装されたものである。基板５１は、１枚の平板に限らず、複数枚の基板の連結により全体が略四角形とされていてもよい。 The light source 50 is a board in which a plurality of light emitting elements 52 such as LEDs are mounted on a substantially quadrangular substrate 51 having a substantially circular opening 13 formed in the center. The substrate 51 is not limited to one flat plate, and the entire substrate 51 may be formed into a substantially quadrangle by connecting a plurality of substrates.

発光素子５２は、表面実装型のＬＥＤパッケージであり、基板５１上に所定間隔をあけて複数個が実装されている。また、発光素子５２は、発光色が昼白色のものと電球色のものを用い、これらを交互に並べて、各列の隣接する発光素子５２と所定間隔をあけて配置してもよい。昼白色と電球色の発光素子５２を流れる電流等を調整することにより、調色が可能となる。また、発光素子５２は発光色が昼白色、電球色以外の発光色を有する発光素子５２を用いてもよい。発光素子５２の個数及びその配列は、所望の出力等に応じて、適宜設定できる。また、ＬＥＤに代えて有機ＥＬ素子を用いてもよい。 The light emitting element 52 is a surface mount type LED package, and a plurality of light emitting elements 52 are mounted on the substrate 51 at predetermined intervals. Further, as the light emitting element 52, one having a neutral white light emitting color and one having a light bulb color may be used, and these may be arranged alternately and arranged at a predetermined interval from the adjacent light emitting element 52 in each row. Color matching is possible by adjusting the current flowing through the light emitting element 52 having a neutral white color and a light bulb color.

The number of light emitting elements 52 and the arrangement thereof can be appropriately set according to a desired output or the like. Further, an organic EL element may be used instead of the LED.

発光素子５２は基板５１上に実装された発光素子５２全体を減光することにより、常夜灯として機能させることができるが、発光素子５２の１つまたは複数の発光素子５２を常夜灯用の発光素子５２とし、輝度調整をすることにより、一般家庭において夜間安心して睡眠できる環境を形成することができる。この場合の発光素子５２は電球色が望ましい。 The light emitting element 52 can function as a nightlight by dimming the entire light emitting element 52 mounted on the substrate 51, but one or more light emitting elements 52 of the light emitting element 52 can be used as a nightlight light emitting element 52. By adjusting the brightness, it is possible to form an environment in which a general household can sleep with peace of mind at night. In this case, the light bulb color is desirable for the light emitting element 52.

基板５１は、中央に開口１３を有し隅部５６が面取りされた略四角形状の平板である。基板５１の表面には、実装された複数の発光素子５２と、常夜灯用の発光素子５２と接続端子５５が配置されている。図１では接続端子５５は略四角形状の基板５１の外周縁部の中央付近の発光素子５２の列間に配置されているが、これに限らず、開口１３周辺や発光素子５２の列の間等に配置してもよい。また、電源装置２０には受信部（図示省略）が配置されている。受信部は外部のリモートコントローラ（図示省略）から送信される赤外線等の指令信号を受信して電源装置２０に送信し、電源装置２０はリモートコントローラからの指令信号にしたがって、光源５０の調光及び調色等の制御をする。リモートコントローラからの指令信号は赤外線信号のほか、Ｗｉ－Ｆｉ（登録商標）信号、Ｂｌｕｅｔｏｏｔｈ（登録商標）信号、移動体通信信号（例えば、第３世代移動通信（３Ｇ）、第５世代移動通信（５Ｇ）、ＬＴＥ（ＬｏｎｇＴｅｒｍＥｖｏｌｕｔｉｏｎ）通信、ＬＰＷＡ（ＬｏｗＰｏｗｅｒ、ＷｉｄｅＡｒｅａ）通信等の信号）等を用いてもよい。 The substrate 51 is a substantially square flat plate having an opening 13 in the center and chamfered corners 56. On the surface of the substrate 51, a plurality of mounted light emitting elements 52, a light emitting element 52 for a nightlight, and a connection terminal 55 are arranged. In FIG. 1, the connection terminals 55 are arranged between rows of light emitting elements 52 near the center of the outer peripheral edge of the substantially square substrate 51, but the present invention is not limited to this, and the connection terminals 55 are not limited to this and are arranged around the openings 13 and between the rows of light emitting elements 52. Etc. may be arranged. Further, a receiving unit (not shown) is arranged in the power supply device 20. The receiving unit receives a command signal such as infrared rays transmitted from an external remote controller (not shown) and transmits it to the power supply device 20, and the power supply device 20 dims the light source 50 and dims according to the command signal from the remote controller. Controls toning, etc. In addition to infrared signals, command signals from remote controllers include Wi-Fi (registered trademark) signals, Bluetooth (registered trademark) signals, mobile communication signals (for example, 3rd generation mobile communication (3G), 5th generation mobile communication (for example). 5G), LTE (Long Term Evolution) communication, LPWA (Low Power, Wide Area) communication and other signals) and the like may be used.

基板５１は、絶縁材であるガラスエポキシ樹脂（ＦＲ－４）の平板からなり、発光素子５２が実装された表面側に銀箔によって配線パターンが形成されたものを用いる。なお、配線パターンはこれに限らず、基板５１の裏面や内部に形成されていてもよい。また、配線パターンの上部、すなわち、基板５１の表面には、反射層として作用する白色のレジスト層が施されている。基板５１の材料としては、絶縁材とする場合には、ガラスエポキシ樹脂（ＦＲ－４）以外に、セラミックス材料、合成樹脂材料等を適用できる。また、基板５１を金属製とする場合には、アルミニウム等の熱伝導性が良好で放熱性に優れたベース板の一面に絶縁層が積層されたベース基板等を適用できる。 The substrate 51 is made of a flat plate of glass epoxy resin (FR-4) which is an insulating material, and a wiring pattern formed by silver foil on the surface side on which the light emitting element 52 is mounted is used. The wiring pattern is not limited to this, and may be formed on the back surface or the inside of the substrate 51. Further, the upper part of the wiring pattern, that is, the surface of the substrate 51 is provided with a white resist layer that acts as a reflective layer. When the substrate 51 is used as an insulating material, a ceramic material, a synthetic resin material, or the like can be applied in addition to the glass epoxy resin (FR-4). Further, when the substrate 51 is made of metal, a base substrate or the like in which an insulating layer is laminated on one surface of a base plate having good thermal conductivity and excellent heat dissipation such as aluminum can be applied.

光拡散カバー３０は、光源５０の光照射面を隈なく覆うように配置され、発光素子５２の直線的な出射光を拡散して全方位的に光を照射できるように作用する。光拡散カバー３０の表面には、基板５１に実装された発光素子５２に逐一対向して光出射面側に光変換部３１として、光拡散カバー３０の表面から突出する凸部３１が設けられている。凸部３１のレンズ効果により、発光素子５２から出射された光は、均等に周囲に拡散され、ＬＥＤ等の発光素子５２の眩しさが軽減されるとともに効率よく光照射される。なお、凸部３１は半球状の凸レンズであることが好ましいが、用途に応じて楕円形状、三角錐、四角錐等の多角錐形状とする等、適宜の形状を採用してもよい。また、光拡散カバー３０の裏面と基板５１との間に発光素子５２が収容される空間を凹レンズ状の凹部３３に形成することで、凸部３１との相乗効果により光拡散効果を得ることができる。そして、光拡散カバー３０の光出射面側を平面とし、光拡散カバー３０の裏面と基板５１との間に発光素子５２が収容される空間を凹レンズ状の凹部３３に形成することで、光拡散性を持たせるようにしてもよい。 The light diffusion cover 30 is arranged so as to completely cover the light irradiation surface of the light source 50, and acts so as to diffuse the linear emitted light of the light emitting element 52 and irradiate the light in all directions. On the surface of the light diffusion cover 30, a convex portion 31 protruding from the surface of the light diffusion cover 30 is provided as a light conversion unit 31 on the light emitting surface side facing the light emitting element 52 mounted on the substrate 51 one by one. There is. Due to the lens effect of the convex portion 31, the light emitted from the light emitting element 52 is evenly diffused to the surroundings, the glare of the light emitting element 52 such as the LED is reduced, and the light is efficiently irradiated. The convex portion 31 is preferably a hemispherical convex lens, but an appropriate shape such as an elliptical shape, a triangular pyramid, or a polygonal pyramid such as a quadrangular pyramid may be adopted depending on the intended use. Further, by forming a space in which the light emitting element 52 is accommodated between the back surface of the light diffusion cover 30 and the substrate 51 in the concave lens-shaped concave portion 33, the light diffusion effect can be obtained by the synergistic effect with the convex portion 31. can. Then, the light emitting surface side of the light diffusion cover 30 is set as a flat surface, and a space in which the light emitting element 52 is accommodated is formed between the back surface of the light diffusion cover 30 and the substrate 51 in the concave lens-shaped recess 33 to diffuse the light. It may be made to have sex.

光拡散カバー３０は、光拡散性を有する透明の樹脂から形成され、例えば、ポリカーボネート（ＰＣ）、ＰＭＭＡ（ポリメタクリル酸メチル）等のアクリル、ＰＳ（ポリスチレン）等が用いられる。 The light diffusion cover 30 is formed of a transparent resin having light diffusion properties, and for example, acrylic such as polycarbonate (PC) and PMMA (polymethylmethacrylate), PS (polystyrene) and the like are used.

カバー部材６０は、別名「グローブ」とも称されるものであり、照明器具１の光照射面の全面を覆っている。カバー部材６０は略円盤形状をなし、透光性を有する材料で形成され、光拡散性と防眩性を付与するため乳白色の材料が用いられる。カバー部材６０は光源５０と光拡散カバー３０と取付具９０の光出射面側の全面を隈なく覆っている。また、カバー部材６０の開口を有する底辺部の内側には縁部の周方向に添って内側に突出する内側凸部６１が設けられている（図９参照）。また、カバー部材６０の材質はＰＭＭＡ（ポリメタクリル酸メチル）等のアクリル樹脂を用いるが、これに限定されず、ポリカーボネート、ポリスチレン等の合成樹脂を用いてもよい。なお、カバー部材６０の表面を磨りガラス状やスリット状の模様に加工することで、光拡散性や防眩性を付与してもよい。 The cover member 60 is also known as a “glove” and covers the entire surface of the light irradiation surface of the lighting fixture 1. The cover member 60 has a substantially disk shape and is made of a translucent material, and a milky white material is used to impart light diffusivity and antiglare property. The cover member 60 completely covers the entire surface of the light source 50, the light diffusion cover 30, and the fixture 90 on the light emitting surface side. Further, an inner convex portion 61 is provided inside the bottom portion having an opening of the cover member 60 so as to project inward along the circumferential direction of the edge portion (see FIG. 9). Further, the material of the cover member 60 is an acrylic resin such as PMMA (polymethyl methacrylate), but the material is not limited to this, and a synthetic resin such as polycarbonate or polystyrene may be used. The surface of the cover member 60 may be polished into a glass-like or slit-like pattern to impart light diffusivity and antiglare property.

The substantially circular main body 10 has a flat portion 11 on the outer peripheral portion along the circumferential direction. The fixtures 90 are arranged at four locations on the flat plate portion 11 at predetermined intervals. The substantially circular light diffusion cover 30 has a narrow edge portion 37 in the circumferential direction of the outermost peripheral portion. A small hole 54 is formed in the edge portion 37, and the small hole 54 communicates with the small hole 95 of the fixture 90 and is fixed to the main body 10. Further, the light source 50 (dotted line portion) is housed inside the light diffusion cover 30.

光拡散カバー３０の表面には、基板５１上に設置された接続端子５５を収納する収納凸部４０が、光照射面側に突出するように設けられている。接続端子５５は光拡散カバー３０の収納凸部４０に設けられた凹部３３内に収納される。また、図３には、光拡散カバー３０は７７個の発光素子５２を覆う光変換部としての凸部３１と、２６個の発光素子５２を覆う小光変換部としての小凸部３２を備えていることが示されているが、発光素子の個数及びその基板５１上の配置は必要な光量等によって適宜変更可能である。凸部３１のすぐ近くに設けられた小凸部３２は、凸部３１に配置された発光素子５２の光照射を補助することで、拡散性と防眩性の向上に寄与する。 On the surface of the light diffusion cover 30, a storage convex portion 40 for accommodating the connection terminal 55 installed on the substrate 51 is provided so as to project toward the light irradiation surface side.

図６は実施形態の照明器具１のカバー部材６０を外した状態における概略断面図である。アダプタ８０は、従来公知のものを利用できる。このようなアダプタ８０の代表例として、図６に示すような扁平な円柱形状をなし、上面側に天井２に配置された既存の引掛シーリングローゼット等の配線器具３の引掛刃係合穴（図示省略）に係合する引掛刃８５を有するものがあげられる。アダプタ８０は、照明器具１内の電源装置２０に接続するコネクタ８４を有する。配線器具３とアダプタ８０は、引掛刃係合穴と引掛刃８５を係合させることで、機械的及び電気的に接続する。 FIG. 6 is a schematic cross-sectional view of the lighting fixture 1 of the embodiment with the cover member 60 removed. As the adapter 80, a conventionally known one can be used. As a typical example of such an adapter 80, it has a flat cylindrical shape as shown in FIG. 6, and has a hook blade engaging hole (illustrated) of a wiring device 3 such as an existing hook ceiling rosette arranged on the ceiling 2 on the upper surface side. (Omitted) includes those having a hooking blade 85 that engages. The adapter 80 has a connector 84 that connects to the power supply device 20 in the luminaire 1.

図９は、図７に示す取付具９０において、カバー部材６０の内側凸部６１を嵌入した状態におけるＡ－Ａ′の水平面でカットした面を上面側からみた断面図である。図７の斜視図、図８の平面図に示すように、取付具９０には、係合部９２の側壁部１０２の収容空間１０３側に、板バネ状の弾性突起部１０５が形成されている。また、弾性突起部１０５に隣接して、内側凸部６１の回動を停止させる停止壁１０８が突出している。
図９に示すように、カバー部材６０の内側凸部６１からさらに突起したストッパー突起部１０９が形成されている場合、カバー部材６０の取付時に、カバー部材６０の内側凸部６１を係合部９２の収容空間１０３に配置して回動（同図において上矢印方向）させると、弾性突起部１０５がストッパー突起部１０９と接触し、弾性突起部１０５が変形してストッパー突起部１０９が弾性突起部１０５を乗り越えるようにカバー部材６０の回動を可能とし、ストッパー突起部１０９がその先の停止壁１０８に突き当たることで、カバー部材の回動が停止する。なお、本実施形態には、カバー部材の内側凸部６１とストッパー突起部１０９とを別個に構成した例を示したが、内側凸部６１とストッパー突起部１０９とを一体化して、一つの凸部として構成することも可能である。このような形態であれば、カバー部材６０の構成をさらに単純化できる。 FIG. 9 is a cross-sectional view of the mounting tool 90 shown in FIG. 7 as seen from the upper surface side of the horizontal plane cut surface of AA ′ in a state where the inner convex portion 61 of the cover member 60 is fitted. As shown in the perspective view of FIG. 7 and the plan view of FIG. 8, the mounting tool 90 is formed with a leaf spring-shaped elastic protrusion 105 on the accommodation space 103 side of the side wall portion 102 of the engaging portion 92. .. Further, adjacent to the elastic protrusion 105, a stop wall 108 for stopping the rotation of the inner convex portion 61 protrudes.
As shown in FIG. 9, when the stopper protrusion 109 further protrudes from the inner convex portion 61 of the cover member 60 is formed, the inner convex portion 61 of the cover member 60 is engaged with the engaging portion 92 when the cover member 60 is attached. When the elastic protrusion 105 is placed in the accommodation space 103 and rotated (in the direction of the upward arrow in the figure), the elastic protrusion 105 comes into contact with the stopper protrusion 109, the elastic protrusion 105 is deformed, and the stopper protrusion 109 becomes the elastic protrusion 109. The cover member 60 can be rotated so as to get over the 105, and when the stopper protrusion 109 abuts on the stop wall 108 beyond the stopper member 60, the rotation of the cover member is stopped. In this embodiment, an example in which the inner convex portion 61 of the cover member and the stopper protrusion 109 are separately configured is shown, but the inner convex portion 61 and the stopper protrusion 109 are integrated into one convex portion. It can also be configured as a part. With such a form, the configuration of the cover member 60 can be further simplified.

取付具９０の材質は、例えば、金属製であってもよいし、樹脂製であってもよい。このような金属の材質としては、例えば、カラー鋼板、亜鉛メッキ鋼板、バネ用ステンレス鋼板等があげられ、樹脂の材質としては、例えば、ＰＰ（ポリプロピレン）、ＰＢＴ（ポリブチレンテレフタレート）等があげられる。 The material of the fixture 90 may be, for example, metal or resin. Examples of such metal materials include colored steel plates, galvanized steel plates, stainless steel plates for springs, and the like, and examples of resin materials include PP (polypropylene), PBT (polybutylene terephthalate), and the like. ..

取付具９０は、光拡散カバー３０及びカバー部材６０と隙間なく密に接しているため、防虫部材を別途用いることなく、簡単な構成で、外部からの虫、粉塵等の光拡散カバー３０やカバー部材６０の内部への侵入を防ぐことができる。さらに、カバー部材６０の内側凸部６１の個数や位置については、それぞれ任意に設定可能である。
また、光源５０から発生した熱は、取付具９０、本体１０を通して外部に放熱される。また、一部の熱はカバー部材６０を介して外部に放熱される。 Since the fixture 90 is in close contact with the light diffusion cover 30 and the cover member 60 without any gaps, the light diffusion cover 30 and the cover for insects, dust, etc. from the outside can be easily configured without using a separate insect repellent member. It is possible to prevent the member 60 from invading the inside. Further, the number and positions of the inner convex portions 61 of the cover member 60 can be arbitrarily set.
Further, the heat generated from the light source 50 is dissipated to the outside through the fixture 90 and the main body 10. Further, some heat is dissipated to the outside via the cover member 60.
