However, the light emitted from the light emitting diode, in particular, has a relatively high luminance, and the light is likely to enter the eyes and may feel dazzling. In recent years, light emitting diodes have become increasingly brighter and more powerful, and there has been a risk of further feeling dazzling, and how to realize a lighting environment in which it is difficult to feel dazzling is an issue.

また、一方、この種の照明器具においては、室内外を問わず環境の厳しい如何なる場所に設置されても、器具の劣化等が生じ難い、例えば、防水・防塵等を施した安全な照明器具の出現が要望されている。さらに、店舗等においては各種、多様な室内装飾等が施され、部屋の雰囲気に合わせることができる照明器具が要望されており、各種照明環境に適合可能な器具を如何に実現するかが課題になっている。   On the other hand, in this type of lighting equipment, the deterioration of the equipment is unlikely to occur regardless of the location where the environment is severe, regardless of whether it is indoors or outdoors. For example, a safe lighting equipment that is waterproof and dustproof. Appearance is desired. Furthermore, in stores and the like, various and various interior decorations are applied, and there is a demand for lighting fixtures that can be adapted to the atmosphere of the room, and the issue is how to realize fixtures that can be adapted to various lighting environments.

A reflector having a widened exit-side opening and having a reflecting surface inclined from the light source-side opening toward the exit-side opening; and having a locking member made of an elastic member, And a mounting member that is mounted by sliding the reflecting surface inclined against the elasticity as a guide and engaging with the reflector.

本発明によれば、係止部材をその弾性に抗して傾斜した反射面をガイドとして摺動させ、反射体に係止することにより装着される装着部材を設けることにより、例えば、広角用の反射板に対して狭角用のグレアレス反射板からなる装着部材を適宜装着することにより、配光角を狭くして眩しさを感じ難い照明器具を構成することが可能となる。   According to the present invention, by providing the mounting member that is mounted by sliding the locking member against the elasticity against the reflecting surface inclined against the elasticity and locking the locking member to the reflector, for example, for a wide angle By appropriately attaching a mounting member made of a narrow-angle glareless reflecting plate to the reflecting plate, it becomes possible to configure a lighting fixture that makes it difficult to feel glare by narrowing the light distribution angle.

本発明において、照明器具は、ダウンライトやスポットライト等住宅用に限らず、店舗、オフィスなど施設・業務用の各種の照明器具を構成してもよい。   In the present invention, the luminaire is not limited to housing such as downlights and spotlights, but may constitute various luminaires for facilities and businesses such as stores and offices.

器具本体は、例えば、円筒状をなす本体の一端部に光源を配設し、内部に光源を点灯させる点灯装置等を収容するもので、光源から発生する熱を放熱するためには、熱伝導性の良好な、アルミニウム、銅、鉄等の金属で構成されることが好ましいが、耐光性、耐熱性および電気絶縁性を有する白色の合成樹脂、例えば、PBT(ポリブチレンテレフタレート)や、アクリルやABS等の合成樹脂で構成したものであってもよい。   The instrument main body is, for example, a light source disposed at one end of a cylindrical main body and containing a lighting device for lighting the light source inside. It is preferable to be made of a metal such as aluminum, copper, or iron having good properties, but a white synthetic resin having light resistance, heat resistance, and electrical insulation, for example, PBT (polybutylene terephthalate), acrylic, It may be composed of a synthetic resin such as ABS.

光源は、発光ダイオードや半導体レーザーなど、半導体を発光源とした半導体発光素子が好適であるが、白熱電球やハロゲン電球、さらには放電灯等で構成されたものであってもよい。光源は複数個で構成されていることが好ましいが、照明の用途に応じて必要な個数は選択され、例えば、1個の光源で構成されるものであってもよい。光源は、点、若しくは面モジュールを構成するように円板状や四角形、六角形などの多角形状、さらには楕円形状等をなすように配設されたものであっても、線モジュールを構成するように長尺なライン状に配設されたものであってもよく、目的とする配光特性を得るための全ての配設形状が許容される。   The light source is preferably a semiconductor light emitting element using a semiconductor as a light source, such as a light emitting diode or a semiconductor laser, but may be an incandescent bulb, a halogen bulb, a discharge lamp, or the like. The light source is preferably composed of a plurality of light sources, but the necessary number is selected according to the use of illumination, and may be composed of, for example, one light source. The light source constitutes a line module even if it is arranged to form a point or a polygonal shape such as a disk, a quadrangle, a hexagon, or an ellipse to constitute a surface module. Thus, it may be arranged in a long line shape, and all arrangement shapes for obtaining a desired light distribution characteristic are allowed.

反射体は、光源に対向する光源側開口部、および光源からの光を出射する拡開した出射側開口部を有し、例えば、部屋の中心部を主として照明するために、周囲にわたり光度の変化が比較的少ない広角用の反射板からの反射光を一部遮光し、所望の配光を得るための反射体が許容される。また、光源側開口部から出射側開口部に向けて傾斜する反射面は、光源から放射される光を反射させ、さらに回転対象となる配光を得るために、光源の発光領域を囲繞するように横断面が円形をなす「浅いすり鉢状」の凹部で形成してもよい。また、例えば、横断面が矩形状をなす「浅いすり鉢状」の凹部などの形状でもよい。また、反射面は連続した曲面で形成されていることが好ましいが、一部に平面状をなす面が形成されたものであってもよい。   The reflector has a light source side opening facing the light source and a widened emission side opening that emits light from the light source. For example, in order to mainly illuminate the center of the room, the luminous intensity changes over the surroundings. A reflector for obtaining a desired light distribution by partially blocking the reflected light from the wide-angle reflecting plate with a relatively small amount of light is allowed. In addition, the reflecting surface that is inclined from the light source side opening toward the emission side opening reflects the light emitted from the light source and surrounds the light emitting region of the light source in order to obtain a light distribution to be rotated. Alternatively, it may be formed of a “shallow mortar-shaped” recess having a circular cross section. Further, for example, the shape may be a “shallow mortar-shaped” recess having a rectangular cross section. Moreover, although it is preferable that the reflective surface is formed by a continuous curved surface, a part of a flat surface may be formed.

Or, conversely, the mounting member is composed of a wide-angle reflecting plate, and is appropriately mounted on the narrow-angle reflecting plate so as to configure a light fixture that is shielded so that the light distribution angle is widened. In short, the light distribution of one reflector is changed to the light distribution of the other reflector, in other words, the light distribution of the two reflectors is relatively changed, and the light source is changed. What is necessary is just to be able to arbitrarily regulate and adjust the light blocking angle, in other words, the irradiation angle.

凹部12cは、個別の6個の反射板を構成するもので、周囲にわたり光度の変化が比較的少ない配光パターンを構成するように、光源であるLED12からの光を広角度に反射させ、さらに回転対象となる配光を得るためにLED12の発光領域を囲繞するように横断面が円形をなす「すり鉢状」の反射面12dを形成し、凹部12cの開口を光出射部とし底部に貫通孔を形成する。これにより、反射板12bは広角用の反射板として構成される。また、反射板12bを構成する円盤の裏面側には、内部に空間部を形成した開口部12eを形成する。   The recess 12c constitutes six individual reflectors, and reflects light from the LED 12 as a light source at a wide angle so as to constitute a light distribution pattern with relatively little change in luminous intensity around the periphery. In order to obtain a light distribution to be rotated, a “mortar-shaped” reflecting surface 12 d having a circular cross section is formed so as to surround the light emitting region of the LED 12, and the opening of the recess 12 c is used as a light emitting portion and a through hole is formed at the bottom. Form. Thereby, the reflecting plate 12b is configured as a wide-angle reflecting plate. Further, an opening 12e having a space inside is formed on the back side of the disk constituting the reflecting plate 12b.

上記に構成された反射板12bには、各LED12を実装した基板12aを、反射板12bの開口部12eに嵌め込み、図示しない係合手段によって基板12aを反射板12bに対して回転しないように仮固定する。   In the reflection plate 12b configured as described above, the substrate 12a on which each LED 12 is mounted is fitted into the opening 12e of the reflection plate 12b, and the substrate 12a is temporarily prevented from rotating with respect to the reflection plate 12b by engagement means (not shown). Fix it.

そして、点灯装置16が配設された器具本体11の収容部11c側からネジ等の固定手段によって反射板12bおよび基板12aを器具本体11側に引き寄せて固定する。これにより、反射板12bの各凹部12cの底面に形成された貫通孔の中心に対して、各LED12が外部に露出して臨むように配置され、各凹部12cにより構成された個別の反射体の光軸y−yとLED11の光軸x−xが略一致した状態に構成され、広角用の光源体Aが形成される。   And the reflecting plate 12b and the board | substrate 12a are pulled near to the instrument main body 11 side by fixing means, such as a screw, from the accommodating part 11c side of the instrument main body 11 in which the lighting device 16 is disposed. Thereby, each LED 12 is arranged so as to be exposed to the outside with respect to the center of the through hole formed in the bottom surface of each recess 12c of the reflection plate 12b, and the individual reflector constituted by each recess 12c. The optical axis yy and the optical axis xx of the LED 11 are configured to substantially coincide with each other, and the light source body A for wide angle is formed.

反射体13は、上記に構成された光源体Aの6個の光源である各LED12に対して1個の共通したリング状をなす反射板を構成するように、LED12側に対向する光源側開口部13a、およびLED12からの光を出射する拡開した出射側開口部13bを形成し、光源側開口部13aから出射側開口部13bに向けて連続して傾斜する反射面13cを形成する。反射面13cは、主に広角用の反射板12bの反射面12dで反射したLED12から放射される光を反射させ、さらに回転対象となる配光を得るために、LED12の発光領域を囲繞するように横断面が円形をなす「浅いすり鉢状」の凹部をなすように構成される。   The reflector 13 has a light source side opening facing the LED 12 side so as to form a common ring-shaped reflector for each LED 12 that is the six light sources of the light source body A configured as described above. The part 13a and the expanded emission side opening 13b that emits the light from the LED 12 are formed, and the reflection surface 13c that is continuously inclined from the light source side opening 13a toward the emission side opening 13b is formed. The reflecting surface 13c mainly reflects the light emitted from the LED 12 reflected by the reflecting surface 12d of the wide-angle reflecting plate 12b and surrounds the light emitting region of the LED 12 in order to obtain a light distribution to be rotated. It is configured to form a “shallow mortar-shaped” recess having a circular cross section.

反射体13は、器具本体11と同様にアルミダイカストでリング状に構成され、一体に形成された支持部13dが器具本体11の一端部に嵌合されて装着される。また、図中13gは、反射体13の光源側開口部13aの開口端に設けられた透光性の合成樹脂等からなるカバー部材(レンズの機能を有していてもよい)である。また、図中18は、器具本体11を天井X等の設置孔に設置するための板バネからなる支持具である。   The reflector 13 is configured in a ring shape by aluminum die casting in the same manner as the instrument main body 11, and an integrally formed support portion 13 d is fitted and attached to one end of the instrument main body 11. Reference numeral 13g in the figure denotes a cover member (which may have a lens function) made of translucent synthetic resin or the like provided at the opening end of the light source side opening 13a of the reflector 13. In the figure, reference numeral 18 denotes a support made of a leaf spring for installing the instrument body 11 in an installation hole such as the ceiling X.

The white synthetic resin, in this embodiment, is formed into a disk shape by PBT (polybutylene terephthalate), and on the surface side, the white inner surface forms a rotating paraboloid surface. The recess 14a is formed integrally. The recess 14a has a hole that is gently inclined so as to shield light from the LED 12 as a light source at a certain angle, reflects the light at a narrow angle, and further emits light from the LED 12 to obtain a light distribution to be rotated. A conical frustum-shaped reflecting surface 14b (inclined at a steeper angle than the inclined angle of the reflecting surface 12d of the reflecting plate 12b of the light source body A) is formed so as to surround the concave portion 14a. The through hole 14d is formed in the bottom part with the opening of the light emitting part 14c. In addition, the glareless reflector 14 made of PBT is provided with a reflective film including the surface and the reflective surface 14b of the concave portion 14a in order to further improve the light reflection performance. To be processed.

20は、リング状をなす本発明の枠部材で、本実施例ではグレアレス反射体14と同様に耐光性、耐熱性および電気絶縁性を有する白色の合成樹脂、本実施例では、PBT(ポリブチレンテレフタレート)により、白色をなすリング状の化粧枠20として構成する。化粧枠20の内径寸法は、円盤状をなすグレアレス反射体14の外径寸法に略等しい寸法に形成し、円盤状をなすグレアレス反射体14を化粧枠20の内周面に嵌合し、化粧枠20の開口部に形成した係合段部20aに係合させる。また、化粧枠20の外径寸法はリング状をなす反射体13における出射側開口部13bの内径寸法に略等しい寸法に形成し、リング状をなす化粧枠20を出射側開口部13bの内周面に嵌合し、反射体13の開口部に形成した係合段部13eに係合させる。   Reference numeral 20 denotes a ring-shaped frame member of the present invention. In this embodiment, a white synthetic resin having light resistance, heat resistance, and electrical insulation, similar to the glareless reflector 14, and in this embodiment, PBT (polybutylene). The ring-shaped decorative frame 20 is formed of white by terephthalate). The inner diameter dimension of the decorative frame 20 is formed to be approximately the same as the outer diameter dimension of the disk-shaped glareless reflector 14, and the disk-shaped glareless reflector 14 is fitted to the inner peripheral surface of the decorative frame 20. Engage with an engaging step 20 a formed in the opening of the frame 20. In addition, the outer diameter of the decorative frame 20 is formed to be approximately equal to the inner diameter of the exit side opening 13b in the reflector 13 having a ring shape, and the outer frame of the ring shape is formed on the inner periphery of the exit side opening 13b. It engages with the surface and engages with an engaging step 13e formed in the opening of the reflector 13.

上記に構成されたグレアレス反射体14および化粧枠20は、図1、図2に示すように、係止部材15により、グレアレス反射体14と化粧枠20が係止され一体化されると共に、一体化されたグレアレス反射体14および化粧枠20が反射体13の光源側開口部13aに係止される。   As shown in FIGS. 1 and 2, the glareless reflector 14 and the decorative frame 20 configured as described above are integrated with the glareless reflector 14 and the decorative frame 20 by the locking member 15. The glareless reflector 14 and the decorative frame 20 that have been converted into the shape are locked to the light source side opening 13 a of the reflector 13.

係止部材15は、図3(a)に示すように、薄いステンレス製の板材を折り曲げて形成することにより弾性が付与されるもので、平坦なベース部15aの一端を略「く」の字形状に折り曲げて当接部15bを形成し、その両側に係合爪片15c、15cを一体に斜めに切起こして形成すると共に、当接部15bの端部をさらに長い略L字形をなすように折り曲げて係止腕15dを形成し、さらにその先端を鉤状に折り曲げて係止片15eを一体に形成する。さらにベース部15aの他端を、上記当接部15bと共に、係合部材15の装着前後の変形に耐える弾性を与えるように略U字形をなすように折り曲げて固定部15fを形成し、固定部の中央部分を略直角に切起こして固定片15gを形成し、固定片の両側に支持片15h、15hを一体に形成する。なお、固定部15fの上端部15jは長い略L字形をなす係止腕15dが撓んだ際のストッパーの役目をなすように形成する(図3(d))。   As shown in FIG. 3 (a), the locking member 15 is provided with elasticity by bending a thin stainless steel plate material, and one end of the flat base portion 15a is substantially "" The contact portion 15b is formed by bending it into a shape, and the engaging claw pieces 15c and 15c are integrally formed obliquely on both sides of the contact portion 15b, and the end portion of the contact portion 15b is formed in a substantially long L shape. The locking arm 15d is formed by bending it into the shape of a hook, and the locking piece 15e is integrally formed by bending the tip of the locking arm 15d into a hook shape. Further, the other end of the base portion 15a is bent together with the abutting portion 15b so as to give elasticity to withstand deformation before and after the engagement member 15 is mounted, thereby forming a fixing portion 15f. The fixed portion 15g is formed by cutting and raising the central portion of the fixed portion at a substantially right angle, and support pieces 15h and 15h are integrally formed on both sides of the fixed piece. The upper end portion 15j of the fixing portion 15f is formed so as to serve as a stopper when the long locking arm 15d having a substantially L shape is bent (FIG. 3D).

上記に構成された係止部材15は、同一形状のものが3本用意され、図2に示すように、化粧枠20の上面の内周面側に略等間隔に支持される。すなわち、化粧枠20の上面の内周面側に略120°の角度で等間隔に支持溝20bが一体に形成され、図3(b)(c)に詳細に示すように、この支持溝20b内に係止部材15のベース部15a、当接部15bおよび固定部15fを、両側の支持片15h、15hをガイドにし、斜めに切起こして形成した係合爪片15c、15cの弾性力に抗しながら挿入する。   Three locking members 15 having the same shape are prepared as described above, and are supported on the inner peripheral surface side of the upper surface of the decorative frame 20 at substantially equal intervals, as shown in FIG. That is, the support grooves 20b are integrally formed at equal intervals at an angle of approximately 120 ° on the inner peripheral surface side of the upper surface of the decorative frame 20, and as shown in detail in FIGS. The base member 15a, the contact portion 15b and the fixing portion 15f of the locking member 15 are provided inside, and the elastic force of the engaging claw pieces 15c and 15c formed by obliquely raising the supporting pieces 15h and 15h on both sides as guides. Insert while resisting.

これにより図3(b)に示すように斜めに切起こして形成した係合爪片15c、15cが支持溝20b内の段部20cに「カッチ」と係合し、係止部材15の抜け止めがなされ支持溝20bに固定される。同時に、略直角に切起こした固定片15gが、円盤状をなすグレアレス反射体14の外周部に形成した溝14eの底面に係止し、固定片15gの弾性力によりグレアレス反射体14を化粧枠20の係合段部20aに対して押圧し、グレアレス反射体14と化粧枠20が係止部材15により強固に係止され一体化される。なお、図2に示すように、係止部材15は、グレアレス反射体14の裏面に形成される6個の凹部14aの周りに形成されるデッドスペースに位置させるように配置し、光源体Aの広角用の反射板12bから光軸x−xに沿ってグレアレス反射体14の凹部14aに向けて出射される光を遮らないように構成する。   As a result, as shown in FIG. 3 (b), the engaging claw pieces 15c, 15c formed by being obliquely raised and engaged with the step 20c in the support groove 20b engage with the “catch”, and the locking member 15 is prevented from coming off. Is fixed to the support groove 20b. At the same time, the fixed piece 15g cut and raised substantially at a right angle is engaged with the bottom surface of the groove 14e formed in the outer peripheral portion of the disk-shaped glareless reflector 14, and the glareless reflector 14 is attached to the decorative frame by the elastic force of the fixed piece 15g. The glareless reflector 14 and the decorative frame 20 are firmly locked by the locking member 15 and integrated with each other. As shown in FIG. 2, the locking member 15 is disposed so as to be positioned in a dead space formed around the six recesses 14 a formed on the back surface of the glareless reflector 14. The light emitted from the wide-angle reflecting plate 12b toward the concave portion 14a of the glareless reflector 14 along the optical axis xx is configured not to be blocked.

また、上記により一体化されたグレアレス反射体14および化粧枠20は、係止部材15により反射体13の光源側開口部13aに係止され装着される。すなわち、図4に示すように、一体化されたグレアレス反射体14および化粧枠20を、反射体13の出射側開口部13b側(下方から)から、図中矢印で示すように係止部材15を光源側開口部13aに向けて挿入する。これにより、係止部材15の長い係止腕15dの先端に形成した鉤状の係止片15eが、その弾性に抗して反射体13の傾斜した反射面13cをガイドとして摺動し、光源側開口部13aの縁を乗り越えて光源側開口部13aの裏側に形成された係合段部13hに係止され固定される。この際、グレアレス反射体14および化粧枠20の自重により垂れ下がらないように、弾性部材からなる係止部材15の剛性を強くしておく。   Further, the glareless reflector 14 and the decorative frame 20 integrated as described above are locked and attached to the light source side opening 13 a of the reflector 13 by the locking member 15. That is, as shown in FIG. 4, the integrated glareless reflector 14 and the decorative frame 20 are engaged with the locking member 15 as shown by an arrow in the figure from the emission side opening 13 b side (from below) of the reflector 13. Is inserted toward the light source side opening 13a. As a result, the hook-shaped locking piece 15e formed at the tip of the long locking arm 15d of the locking member 15 slides against the elasticity using the inclined reflecting surface 13c of the reflector 13 as a guide, and the light source Overcoming the edge of the side opening 13a, it is locked and fixed to an engaging step 13h formed on the back side of the light source side opening 13a. At this time, the rigidity of the locking member 15 made of an elastic member is increased so that the glareless reflector 14 and the decorative frame 20 do not hang down due to their own weight.

これにより、グレアレス反射体14および化粧枠20は、係止部材15により反射体13の光源側開口部13aに係止されることによって装着され、光源体Aの広角用の反射板12bの光軸と狭角用の反射板からなるグレアレス反射体14の光軸が光軸x−x線上で略一致する。さらに、グレアレス反射体14の外周と出射側開口13bの内周との間が白色の綺麗な化粧枠20で閉塞される。上記により、図1に示すように、広角用の反射板12bの光出射部側に狭角用の反射板からなるグレアレス反射体14が装着された狭角用、すなわち、眩しさを感じ難くさせるダウンライト10が構成される。   Thus, the glareless reflector 14 and the decorative frame 20 are mounted by being locked to the light source side opening 13a of the reflector 13 by the locking member 15, and the optical axis of the wide-angle reflecting plate 12b of the light source A. And the optical axis of the glareless reflector 14 formed of a narrow-angle reflecting plate substantially coincide with each other on the optical axis xx. Furthermore, the space between the outer periphery of the glareless reflector 14 and the inner periphery of the exit side opening 13b is closed with a beautiful white decorative frame 20. As described above, as shown in FIG. 1, the glareless reflector 14 made of a narrow-angle reflector is mounted on the light-emitting portion side of the wide-angle reflector 12b, so that it is difficult to feel glare. A downlight 10 is configured.

なお、上記により反射体13に装着されたグレアレス反射体14および化粧枠20は、次のようにして取り外すことができる。図3(d)に示すように、化粧枠20に略等間隔に形成された支持溝20bの内、1箇所の支持溝には、取り外し用の貫通孔20dが化粧枠20の表面から裏面にわたって形成され、細いドライバ等の冶具Tを貫通孔20dから図中A方向に挿入し、係止部材15の「く」の字状に折り曲げられた当接部15bの傾斜部分を、その弾性力に抗して押圧する。これにより、長い係止腕15dが水平方向にずれながら矢印Bの方向に撓み、鉤状の係止片15eが反射体13の係合段部13hからずれて係合が解除される。そして、残りの2個の係止片15eを係合段部13hからずらして引き外すことにより、グレアレス反射体14および化粧枠20を反射体13から取り外すことができる。これにより、一体化されたグレアレス反射体14および化粧枠20が反射体13に対して着脱が可能になるように装着され、装着されたグレアレス反射体14および化粧枠20を適宜選択して取り外すことにより、元の広角用の反射板12bを有するダウンライト10´に戻すことができる(図5)。   The glareless reflector 14 and the decorative frame 20 attached to the reflector 13 as described above can be removed as follows. As shown in FIG. 3 (d), among the support grooves 20 b formed in the decorative frame 20 at approximately equal intervals, one support groove has a through hole 20 d for removal extending from the front surface to the back surface of the decorative frame 20. A formed jig T such as a thin screwdriver is inserted from the through hole 20d in the direction A in the figure, and the inclined portion of the abutting portion 15b of the locking member 15 bent in a "<" shape is used as its elastic force. Press against. As a result, the long locking arm 15d is bent in the direction of the arrow B while being displaced in the horizontal direction, and the hook-shaped locking piece 15e is displaced from the engagement step portion 13h of the reflector 13 to be disengaged. Then, the glareless reflector 14 and the decorative frame 20 can be detached from the reflector 13 by shifting the remaining two locking pieces 15e away from the engaging step portion 13h. Thereby, the integrated glareless reflector 14 and the decorative frame 20 are mounted so as to be detachable from the reflector 13, and the mounted glareless reflector 14 and the decorative frame 20 are appropriately selected and removed. Thus, it is possible to return to the downlight 10 ′ having the original wide-angle reflecting plate 12 b (FIG. 5).

次に、上記に構成された広角用のダウンライト10´およびグレアレス反射体14を装着した狭角用のダウンライト10の作用につき説明する。まず、広角用のダウンライトにつき説明する。   Next, the operation of the wide-angle downlight 10 'configured as described above and the narrow-angle downlight 10 equipped with the glareless reflector 14 will be described. First, a wide-angle downlight will be described.

上記構成の広角用のダウンライト10´(図5)は、図6(a)に示すように、被設置面である天井X等に単体若しくは複数個を送り用ケーブルにより接続させて設置される。点灯すると、各LED12が発光し、LEDから放射された光は、図中矢印で示すように、先ず、光源体Aの広角用の反射板12bの反射面12dで反射しながら光出射部から放射され、さらに、反射光の一部がリング状をなす反射体13の反射面13cで反射され、周囲にわたり光度の変化が比較的少ない配光特性をもって、部屋の中心部が比較的明るく、周囲にわたって徐々に暗くなるダウンライトとしての配光特性をもった照明を行うことができる。   As shown in FIG. 6A, the wide-angle downlight 10 ′ (FIG. 5) having the above-described configuration is installed by connecting a single or a plurality of them to the ceiling X, which is the installation surface, using a feeding cable. . When lit, each LED 12 emits light, and light emitted from the LED is first emitted from the light emitting part while being reflected by the reflecting surface 12d of the wide-angle reflecting plate 12b of the light source A, as indicated by arrows in the figure. Further, a part of the reflected light is reflected by the reflecting surface 13c of the reflector 13 having a ring shape, has a light distribution characteristic in which the change in luminous intensity is relatively small over the surroundings, the center of the room is relatively bright, and the surroundings are spread over the surroundings. Illumination with light distribution characteristics as a downlight that gradually darkens can be performed.

このように、LED12から放射された光を広角用の反射板12bで配光制御し、LEDの遮光角を反射板12bで規制すると共に、反射板12bの反射光を反射体13で遮光することができるので、所望の配光を得ると共に眩しさを低減させることができる。しかし、使用目的によっては、LED12および反射板12bの遮光角をさらに大きくする必要がある。また、上記構成では、リング状をなす反射体13の反射面13cで光を反射させるために光が目に入り眩しさを感じ易くなる。   In this way, light distribution from the LED 12 is controlled by the wide-angle reflecting plate 12b, the light-shielding angle of the LED is regulated by the reflecting plate 12b, and the reflected light from the reflecting plate 12b is shielded by the reflector 13. Therefore, the desired light distribution can be obtained and the glare can be reduced. However, depending on the purpose of use, it is necessary to further increase the light shielding angle of the LED 12 and the reflecting plate 12b. Moreover, in the said structure, since light is reflected by the reflective surface 13c of the reflector 13 which makes | forms a ring shape, light enters into eyes and it becomes easy to feel dazzling.

これを解決するために、上記に構成され天井X等に設置されたダウンライト10´の広角用の反射板12bに対し、狭角用の反射板であるグレアレス反射体14を選択して装着し、図1に示すダウンライト10を構成する。すなわち、別部品として用意した、グレアレス反射体14および化粧枠20を用い、図4に示すように、係止部材15により係止し一体化したグレアレス反射体14および化粧枠20を、下方に面する反射体13の出射側開口部13bから上方に向けて挿入し、係止部材15の鉤状の係止片15eを、その弾性に抗して反射体13の傾斜した反射面13cをガイドとして利用して摺動させ光源側開口部13aの係合段部13hに鉤状の係止片15eを係止して装着し狭角用のダウンライト10を構成する。   In order to solve this problem, the glareless reflector 14 which is a narrow-angle reflector is selected and mounted on the wide-angle reflector 12b of the downlight 10 'configured as described above and installed on the ceiling X or the like. 1 constitutes the downlight 10 shown in FIG. That is, using the glareless reflector 14 and the decorative frame 20 prepared as separate parts, as shown in FIG. 4, the glareless reflector 14 and the decorative frame 20 that are locked and integrated by the locking member 15 face downward. The reflector 13 is inserted upward from the exit side opening 13b of the reflector 13, and the hook-like locking piece 15e of the locking member 15 is used as a guide against the elasticity of the reflecting surface 13c against the elasticity. The narrow-angle downlight 10 is configured by sliding and using the hook-shaped locking piece 15e and mounting it on the engaging step 13h of the light source side opening 13a.

この狭角用のダウンライトを点灯すると、各LED12が発光し、LEDから放射された光は、図6(b)の矢印で示すように、先ず光源体Aの広角用の反射板12bの反射面12dで反射しながら光出射部から放射され、さらに、グレアレス反射体14の狭角をなす反射面14bで反射しながら光出射部14cから放射される。この際、リング状をなす反射体13の反射面13cで光は反射されず、狭角をなすグレアレス反射体14の反射面14bで反射させるために配光角が比較的小さくなる。また、LED12および広角用の反射板12bの遮光角をグレアレス反射体14によってダウンライト10´の遮光角よりも大きくすることができ、眩しさを感じることが少ない照明を行うことができる。   When the narrow-angle downlight is turned on, each LED 12 emits light, and the light emitted from the LED is first reflected by the wide-angle reflecting plate 12b of the light source A as shown by the arrow in FIG. The light is emitted from the light emitting portion while being reflected by the surface 12d, and is further emitted from the light emitting portion 14c while being reflected by the reflection surface 14b forming a narrow angle of the glareless reflector 14. At this time, the light is not reflected by the reflecting surface 13c of the reflector 13 having a ring shape, and is reflected by the reflecting surface 14b of the glareless reflector 14 having a narrow angle, so that the light distribution angle is relatively small. Further, the light shielding angle of the LED 12 and the wide-angle reflecting plate 12b can be made larger than the light shielding angle of the downlight 10 ′ by the glareless reflector 14, and illumination with less glare can be performed.

また、狭角をなすグレアレス反射体14の反射体13への装着は、設置する現場に合わせて、照明の状況をみながら適宜選択して装着する。また、複数台設置されたダウンライトに対して装着が必要か否かを選択しながら調整し、全体として目的とする配光特性を作り出すようにする。また、設置後に照明環境を変更する場合にも、同様に現地において装着の可否を適宜選択して調整し、変更された照明環境に合わせた目的とする配光特性を作り出すようにする。これらに伴うグレアレス反射体14の着脱操作は、化粧枠20の取り外し用の貫通孔20dにドライバ等の冶具Tを挿入して行う。   In addition, the glareless reflector 14 having a narrow angle is attached to the reflector 13 by appropriately selecting and attaching the glareless reflector 14 according to the installation site while observing the lighting conditions. In addition, it is adjusted while selecting whether or not it is necessary to install a plurality of downlights so that a desired light distribution characteristic as a whole is created. Similarly, when the lighting environment is changed after installation, similarly, whether or not the lighting environment is installed is appropriately selected and adjusted to create a desired light distribution characteristic in accordance with the changed lighting environment. The attachment / detachment operation of the glareless reflector 14 is performed by inserting a jig T such as a screwdriver into the through hole 20d for removing the decorative frame 20.

以上、本実施例によれば、広角用の反射板12bを有する照明器具の反射体13に対し、光源であるLED12の遮光角を規制する狭角用の反射板であるグレアレス反射体14を適宜選択して装着することができるように構成したので、眩しさを感じ難くすることが可能な照明器具を提供することができ、目的とする眩しさを感じ難い照明環境を容易に作り出すことができる。   As described above, according to the present embodiment, the glareless reflector 14, which is a narrow-angle reflector that regulates the light-shielding angle of the LED 12 that is the light source, is appropriately used for the reflector 13 of the lighting fixture having the wide-angle reflector 12 b. Since it is configured so that it can be selected and mounted, it is possible to provide a lighting fixture that can make it difficult to feel glare, and to easily create a lighting environment that makes it difficult to feel the desired glare. .

グレアレス反射体14の反射体13に対する装着は、係止部材15の鉤状の係止片15eを、その弾性に抗して反射体13の傾斜した反射面13cをガイドとして利用し摺動させるようにしたので、グレアレス反射体14を反射体13に単純に挿入するワンタッチの簡単な操作で、かつ確実に装着することができる。   The glareless reflector 14 is attached to the reflector 13 such that the hook-like locking piece 15e of the locking member 15 is slid using the inclined reflecting surface 13c of the reflector 13 as a guide against its elasticity. As a result, the glareless reflector 14 can be securely attached by a simple one-touch operation in which the glareless reflector 14 is simply inserted into the reflector 13.

グレアレス反射体14は、反射体13の光源側開口部13aにワンタッチで装着するのみで、自動的に光源体Aの広角用の反射板12bの光軸と、グレアレス反射体14の光軸を簡単かつ確実に略一致させることができる。さらに、化粧枠20を設け、グレアレス反射体14は化粧枠20と一体化され装着されるようにしたので、グレアレス反射体14の外周と出射側開口部13bの内周との間が化粧枠20で閉塞され、光源であるLED12に対する防塵・防水効果を図ることができ、環境の厳しい場所に設置されても劣化し難い安全な照明器具を提供することができる。同時に綺麗な化粧枠で閉塞することができ、部屋の雰囲気に合わせた外観のよい照明器具を提供することができる。さらに、グレアレス反射体14の外周と出射側開口13bの内周との間の隙間がなくなってLED12から放射される光が隙間から漏れることなく光ロスを発生させることがない。また、グレアレス反射体14は、アルミニウムによる蒸着膜を施して鏡面に加工されており、装着の際などに手で触れると鏡面が汚れる恐れがあるが、グレアレス反射体14は化粧枠20と一体化されているので、化粧枠20のみを掴んで反射体13への装着が行えるので、鏡面加工されたグレアレス反射体14の表面等に手が触れることなく汚れを防止することができる。   The glareless reflector 14 is simply mounted on the light source side opening 13a of the reflector 13 with one touch, and the optical axis of the wide-angle reflecting plate 12b of the light source body A and the optical axis of the glareless reflector 14 are simply set. And it can be made to substantially agree | coincide reliably. Further, since the decorative frame 20 is provided and the glareless reflector 14 is integrated with the decorative frame 20, the decorative frame 20 is between the outer periphery of the glareless reflector 14 and the inner periphery of the emission side opening 13b. Therefore, it is possible to provide a dustproof / waterproof effect for the LED 12 that is a light source, and it is possible to provide a safe lighting device that is difficult to deteriorate even when installed in a severe environment. At the same time, it is possible to provide a lighting device that can be closed with a beautiful decorative frame and has a good appearance according to the atmosphere of the room. Furthermore, there is no gap between the outer circumference of the glareless reflector 14 and the inner circumference of the exit side opening 13b, so that light emitted from the LED 12 does not leak from the gap and no light loss occurs. Further, the glareless reflector 14 is processed into a mirror surface by applying a vapor deposition film made of aluminum, and the mirror surface may become dirty when touched with a hand when wearing it, but the glareless reflector 14 is integrated with the decorative frame 20. Therefore, since only the decorative frame 20 can be grasped and attached to the reflector 13, it is possible to prevent contamination without touching the surface of the glareless reflector 14 that has been mirror-finished.

また、反射体13に装着されるグレアレス反射体14、化粧枠20および係止部材15は一体化され、反射体13の反射面13cで囲われる「浅いすり鉢状」の凹部からなる空きスペースに収納される大きさに構成したので、既存の広角用の照明器具の外径寸法および高さ寸法を大きくする必要がなく小型化を達成することができる。   In addition, the glareless reflector 14, the decorative frame 20, and the locking member 15 attached to the reflector 13 are integrated and accommodated in an empty space formed by a “shallow mortar-shaped” recess surrounded by the reflecting surface 13 c of the reflector 13. Since it is configured in such a size, it is not necessary to increase the outer diameter and height of the existing wide-angle lighting fixture, and it is possible to achieve downsizing.

係止部材15は、1個の部品でグレアレス反射体14と化粧枠20を係止すると共に、係止されたグレアレス反射体14および化粧枠20を反射体13の光源側開口部13aに係止させることができるので、部品点数を削減することができコスト的に有利になる。   The locking member 15 locks the glareless reflector 14 and the decorative frame 20 with one component, and locks the locked glareless reflector 14 and the decorative frame 20 to the light source side opening 13 a of the reflector 13. Therefore, the number of parts can be reduced, which is advantageous in terms of cost.

係止部材15は、薄いステンレス製の板材等を折り曲げることにより、グレアレス反射体14と化粧枠20を係止する固定片15g、グレアレス反射体14および化粧枠20を反射体13の光源側開口部13aに係止させるための鉤状の係止片15e、さらに係止部材15自体を化粧枠20の支持溝20bに支持するための係合爪片15c、15c等を一体に形成したので、1個の部品で多様な機能を果たすことができ、さらなる部品点数の削減が可能となり、コスト的にも有利でかつ組立も支持溝20bに挿入する単純な作業で行うことができ、量産化に適した照明器具を提供することができる。また、グレアレス反射体14は、係止部材15の固定片15gの弾性力により化粧枠20の係合段部20aに対して押圧されて支持されるので、簡単に外れることなく強固に固定することができる。   The locking member 15 is formed by bending a thin stainless steel plate or the like to fix the glareless reflector 14 and the decorative frame 20, the glareless reflector 14 and the decorative frame 20 to the light source side opening of the reflector 13. Since hook-shaped locking pieces 15e for locking to 13a, and engaging claw pieces 15c, 15c for supporting the locking member 15 itself in the support groove 20b of the decorative frame 20, are integrally formed. Individual parts can perform various functions, and the number of parts can be further reduced, which is advantageous in terms of cost and can be assembled by a simple operation of inserting into the support groove 20b, and is suitable for mass production. Lighting equipment can be provided. Further, since the glareless reflector 14 is supported by being pressed against the engaging step portion 20a of the decorative frame 20 by the elastic force of the fixing piece 15g of the locking member 15, it is firmly fixed without being easily detached. Can do.

グレアレス反射体14および化粧枠20が、反射体13から取り外すことができるので、元の広角用の反射板12bを有するダウンライト10´に簡単に戻すことができる。さらに、設置する現場の状況に合わせて、照明の状況をみながら適宜選択して装着することもでき、各種の照明環境に合わせた目的とする配光特性を容易に作り出すことができる。また、雰囲気に合わせて都度、配光を変更することもでき、さらに、各種・多様な配光特性を有するバリエーションに富んだ照明器具を提供することも可能となる。また、その取り外しは化粧枠20の取り外し用の貫通孔20dにドライバ等の冶具Tを単に挿入するだけの操作で行うことができ、施工のし易い照明器具を提供することができる。また、取り外し用の貫通孔20dは、小型の治具が入る程度の小さな孔を形成するのみで済み、化粧枠20の外観を損なうことがない。また、係止部材15の係合を解除するための取り外し用の貫通孔20dは、3個の支持溝20b全てに設けるようにしてもよい。   Since the glareless reflector 14 and the decorative frame 20 can be detached from the reflector 13, it can be easily returned to the downlight 10 'having the original wide-angle reflector 12b. Furthermore, according to the situation of the installation site, it can also be appropriately selected and installed while observing the illumination situation, and the desired light distribution characteristics suitable for various illumination environments can be easily created. In addition, it is possible to change the light distribution each time according to the atmosphere, and it is also possible to provide a variety of lighting fixtures having various and various light distribution characteristics. Moreover, the removal can be performed by simply inserting a jig T such as a driver into the through-hole 20d for removing the decorative frame 20, and a lighting device that is easy to construct can be provided. Further, the through-hole 20d for removal only needs to form a small hole enough to accommodate a small jig, and the appearance of the decorative frame 20 is not impaired. Further, the through holes 20d for removal for releasing the engagement of the locking members 15 may be provided in all the three support grooves 20b.

また、反射体13に適宜選択して装着されるグレアレス反射体14により、広角の配光パターンを狭角の配光パターンに必要に応じて容易に変更させることができるので、商品としての在庫は広角用の照明器具10´のみとし、狭角用の照明器具は広角用の照明器具10´の反射体13に狭角用のグレアレス反射体14を装着することにより構成するようにすれば、商品ラインナップを減じることなく、かつ商品在庫を減少させることも可能となる。   Further, the glareless reflector 14 that is appropriately selected and mounted on the reflector 13 can easily change the wide-angle light distribution pattern to the narrow-angle light distribution pattern as necessary. If only the wide-angle lighting fixture 10 ′ is used, and the narrow-angle lighting fixture is configured by mounting the glareless reflector 14 for the narrow angle on the reflector 13 of the wide-angle lighting fixture 10 ′, It is also possible to reduce product inventory without reducing the lineup.
