Description
本発明は、建屋の天井等に設置される水銀灯など照明器具に取り付けられ、下方の床面などを照明するのに好適な反射笠に関する。 The present invention relates to a reflective shade which is attached to a lighting fixture such as a mercury lamp installed on a ceiling of a building and is suitable for illuminating a floor surface below.
従来、建屋の天井等に取り付けられる照明器具、たとえばダウンライト等に用いられる反射笠としては、アルミ板をへら絞り加工したものが用いられていたが、加工時の肌荒れがひどく、反射面を鏡面に仕上げることとができなかった。このため、あらかじめアルミ蒸着等によって鏡面状に仕上げた複数枚の分割反射板を周回に組み合わせた照明器具の反射笠が提案されている。 Conventionally, as a reflective shade used for lighting fixtures attached to the ceiling of a building, for example, downlights, etc., an aluminum plate that has been subjected to spatula processing has been used, but the rough surface during processing is severe, and the reflective surface is a mirror surface I could not finish it. For this reason, a reflector shade for a lighting fixture has been proposed in which a plurality of divided reflectors that have been mirror-finished in advance by aluminum vapor deposition or the like are combined in a circle.
例えば、特許文献１（特開２００８−９１２０８号公報）には、ランプを取り付けるためのランプホルダと、当該ランプホルダに取り付けたシェードと、当該シェード内部に取り付けた略円錐状の反射板とを含み、当該反射板がランプホルダに取り付けられたランプを包囲する上部反射板と下部反射板を含むように構成した照明器具が記載されている。 For example, Patent Document 1 (Japanese Patent Laid-Open No. 2008-91208) includes a lamp holder for mounting a lamp, a shade attached to the lamp holder, and a substantially conical reflector attached inside the shade. A lighting fixture is described in which the reflector includes an upper reflector and a lower reflector that surround the lamp attached to the lamp holder.
また、特許文献２（特開２００７−２４２４０９号公報）には、天井から吊下げられる反射傘に配置され、前記反射傘の傘部内面に取り付けられる八面体の反射面を備えた照明器具が記載されている。 Further, Patent Document 2 (Japanese Patent Application Laid-Open No. 2007-242409) describes a lighting fixture provided with an octahedral reflecting surface that is disposed on a reflecting umbrella suspended from a ceiling and attached to the inner surface of the umbrella portion of the reflecting umbrella. Has been.
しかしながら、前記特許文献に記載の技術のものは、配光制御の観点やコスト面などで改善の余地があった。すなわち前記従来の照明器具におけるランプを囲む反射笠は、反射部分が周方向に沿ってシェードや多数のリベットで固定されるために、笠の組立・製作工程が煩雑であり使用目的に応じた調光条件などの設定が困難である。さらに、反射板の部分が周方向に屈曲させた多角形状の場合、スムースな湾曲形状の笠に比べれば、周方向での照度均一性が劣るという欠点もあった。また、省資源、軽量化のためには、より薄い反射板の使用が望まれるが、薄板にすると配光制御した反射笠の所定形状の維持が難しくなる。この傾向は、特に周方向で屈曲部のない湾曲面から反射笠が構成される場合に著しい。
本発明は前記従来の課題を解決するためになされたもので、配光制御可能で消費電力を増やすことなく照明器具の照度向上が図れ、反射板の固定方法を工夫することにより、構造が簡単で形状の保持性に優れ、軽量安価な照明器具の反射笠を提供することを目的とする。
However, the technique described in the patent document has room for improvement in terms of light distribution control and cost. In other words, the reflective shade surrounding the lamp in the conventional lighting fixture is fixed with a shade and a large number of rivets along the circumferential direction, so the assembly and production process of the shade is complicated, and the reflective shade is adjusted according to the purpose of use. It is difficult to set light conditions. Furthermore, in the case of a polygonal shape in which the reflecting plate portion is bent in the circumferential direction, there is a disadvantage that the illuminance uniformity in the circumferential direction is inferior compared to a smooth curved shade. Further, in order to save resources and reduce the weight, it is desirable to use a thinner reflector. However, if a thin plate is used, it is difficult to maintain a predetermined shape of the reflector shade that is light-distributed. This tendency is remarkable particularly when the reflective shade is formed of a curved surface having no bent portion in the circumferential direction.
The present invention has been made in order to solve the above-mentioned conventional problems. Light distribution control is possible, the illuminance of the lighting fixture can be improved without increasing power consumption, and the structure of the reflector can be simplified by devising the fixing method of the reflector. An object of the present invention is to provide a reflective shade for a lighting fixture that is excellent in shape retention and lightweight and inexpensive.

It is characterized by being provided in a shape.
（３）本発明の照明器具の反射笠は、前記（１）の照明器具の反射笠において、隣接する各段の傾斜部は、一方の傾斜部の反射板の上端又は下端が他方の傾斜部の反射板の下端又は上端に突出して配置され、且つ固定プレートには、傾斜部の反射板端部の突出を許容しその傾斜角度を固定調整する配光制御部が設けられていることを特徴とする。 (3) The reflecting shade of the lighting fixture according to the present invention is the reflecting shade of the lighting fixture according to (1), wherein the inclined portion of each adjacent step is such that the upper end or lower end of the reflecting plate of one inclined portion is the other inclined portion. A light distribution control unit is provided that protrudes from the lower end or upper end of the reflection plate, and the fixed plate is provided with a light distribution control unit that allows the reflection plate end portion of the inclined portion to protrude and fixes the inclination angle. And
（４）本発明の照明器具の反射笠は、前記（１）〜（３）の照明器具の反射笠において、各傾斜部は周方向において屈曲部のない円錐台状であることを特徴とする。 (4) The reflecting shade of the lighting fixture of the present invention is the reflecting shade of the lighting fixture of (1) to (3), wherein each inclined portion has a truncated cone shape without a bent portion in the circumferential direction. .
（５）本発明の照明器具の反射笠は、前記（１）〜（４）の照明器具の反射笠において、前記傾斜部は、その内面に銀鏡処理を施した金属板からなることを特徴とする。 (5) The reflecting shade of the lighting fixture of the present invention is the reflecting shade of the lighting fixture of (1) to (4), wherein the inclined portion is made of a metal plate having a silver mirror treatment on its inner surface. To do.
本発明の反射笠は、鏡面処理金属薄板（アルミニウムや表面処理鋼板の反射板）を曲面にした傾斜部とし上下段に組み合わせ、帯板を屈曲させたフレームで支持固定されるという、単純な加工方法、構成で形成されており、それぞれ扇状の反射板を周状に連結して形成された傾斜部の傾斜角度を調整することによって、光源ランプの反射方向を調整（配光制御）することができる。また、これまでに比べ低コストで照明器具の照度向上を図れるので、器具効率がアップし消費電力を低く抑えてエネルギー使用量を削減することが可能となる。 The reflective shade of the present invention is a simple process in which a mirror-finished metal thin plate (aluminum or surface-treated steel plate reflector) is combined with upper and lower tiers and is supported and fixed by a frame in which the strip is bent. The light source lamp reflection direction can be adjusted (light distribution control) by adjusting the inclination angle of the inclined portion formed by connecting the fan-like reflection plates in a circumferential shape. it can. In addition, since the illuminance of the lighting fixture can be improved at a lower cost than before, the fixture efficiency is improved, and the amount of energy used can be reduced while suppressing the power consumption.
さらに、反射板を絞り加工方法などを用いて形成する場合に比べ、加工機械設備による制約を受けることがないので、反射笠を簡易に加工形成することができ、大型の反射笠が製作しやすい。
また、それぞれ扇状の反射板を周状に連結して形成された傾斜部が、反射板の周方向と直角方向に帯板を屈曲させて形成した固定プレートによって支持固定されているので、各傾斜部の傾斜角度を所定の角度で正確に調整して配光制御をすることができ、消費電力を増やすことなく照度向上ができ照明器具の器具効率向上を図ることができる。
Furthermore, compared to the case where the reflector plate is formed using a drawing method or the like, it is not subject to restrictions due to processing machine equipment, so the reflector shade can be easily formed and a large reflector shade can be easily manufactured. .
In addition, the inclined portion formed by connecting the fan-shaped reflectors in a circumferential shape is supported and fixed by a fixed plate formed by bending the belt plate in a direction perpendicular to the circumferential direction of the reflector plate. The light distribution can be controlled by accurately adjusting the inclination angle of the unit at a predetermined angle, and the illuminance can be improved without increasing the power consumption, thereby improving the efficiency of the luminaire.
また、各段の傾斜部の隣接部で一方の反射板端部を突出させて配置することにより、各傾斜部間での光の漏れを少なくできるので、照明効率の向上を図ることができる。このような傾斜部の端部までを含めた傾斜角度の調整は、例えば、互いに隣接する各傾斜部の反射板の端部や固定プレートにその傾斜角度を固定調整する配光制御部を設けることで配光条件を容易に設定できる。 In addition, by arranging one end of the reflecting plate so as to protrude from the adjacent portion of the inclined portion of each step, light leakage between the inclined portions can be reduced, so that the illumination efficiency can be improved. Such adjustment of the inclination angle including the end of the inclined portion is performed, for example, by providing a light distribution control unit that fixes and adjusts the inclination angle at the end portion of the reflecting plate of each adjacent inclined portion or a fixed plate. The light distribution conditions can be set easily.
本実施形態に係る照明器具の反射笠は、照明ランプの周囲に配置され内面鏡面状の椀状を成し、反射笠の軸線方向に対して傾斜角度の異なる上下２段以上の傾斜部を組み合わせた反射笠であって、各段の傾斜部はそれぞれ扇状の単数または複数の反射板を周状に連結して形成され、且つ反射笠は前記傾斜部の周方向と直角方向に上下の傾斜部を横断して伸延した固定プレートによって支持固定されている。
反射笠の内面をそれぞれ傾斜角度の異なる上下２段以上の傾斜部から形成したので、各傾斜部の傾斜角度を調整することによって光源ランプの反射方向を調整することができる。
The reflective shade of the lighting fixture according to the present embodiment has a bowl-like shape that is arranged around the illumination lamp and has a mirror-like inner surface, and is composed of two or more upper and lower slope portions having different slope angles with respect to the axial direction of the reflective shade. The inclined portions of each step are formed by connecting one or more fan-shaped reflectors in a circumferential shape, and the reflective shades are vertically inclined portions in a direction perpendicular to the circumferential direction of the inclined portions. It is supported and fixed by a fixing plate extending across.
Since the inner surface of the reflective shade is formed from two or more inclined portions having different inclination angles, the reflection direction of the light source lamp can be adjusted by adjusting the inclination angle of each inclination portion.
一般に、照明器具は、例えば、工場、店舗、ガソリンスタンド等の屋内の天井や、屋外の仮設テント等に取り付けられ、光源ランプを取り付けるためのランプホルダと、ランプホルダに椀状に取り付けられ内面に複数の傾斜部を有した反射笠と、により構成されている。
そして、反射笠は、照明器具における光源ランプの反射部材であって、水銀灯やメタルハライドランプ、白熱灯、ＬＥＤランプなどの光源の周囲に配置され、その背面側から椀状に囲むようにして、その反射光を照明器具に対向して置かれた対象物に適性かつ効率的に照射するように機能する。
In general, lighting fixtures are attached to indoor ceilings such as factories, stores, and gas stations, or temporary temporary tents, etc., and a lamp holder for attaching a light source lamp, and a lamp holder attached to the lamp holder in a bowl shape. And a reflective shade having a plurality of inclined portions.
The reflection shade is a reflection member of a light source lamp in a lighting fixture, and is disposed around a light source such as a mercury lamp, a metal halide lamp, an incandescent lamp, and an LED lamp, and is reflected from the back side thereof in a bowl shape. Functions to irradiate the object placed facing the lighting fixture appropriately and efficiently.
傾斜部は、扇状の単数または複数の反射板を周状に連結して形成された円錐台の形状を有しており、軸方向すなわち傾斜部の周方向と直角方向に伸延した固定プレートによって支持固定されている。
また、傾斜部は、反射板の端部にその傾斜角度を固定調整する配光制御部が設けられており、各傾斜部の端部までを含めた傾斜角度を調整することによって光源ランプの反射方向を調整することができるようにされている。
反射板の素材としては、その反射面が銀鏡処理されて形成された金属薄板や、アルミなどの金属蒸着処理やアルミ箔などがラミネート加工された半透明又は不透明プラスチック板、紙板などを適用することができる。反射板の板厚としては、それが周状に曲げ加工ができ、反射笠の傾斜部として形状保持ができるものであれば特に限定されるものではないが、例えばアルミや表面処理鋼板などの金属板の場合、０．２ｍｍ〜２ｍｍが、軽量かつ加工がしやすく入手も容易なので好適である。
The inclined portion has a truncated cone shape formed by connecting one or more fan-shaped reflectors in a circumferential shape, and is supported by a fixed plate extending in the axial direction, that is, in a direction perpendicular to the circumferential direction of the inclined portion. It is fixed.
In addition, the inclined portion is provided with a light distribution control unit that fixes and adjusts the inclination angle at the end of the reflector, and the reflection of the light source lamp is adjusted by adjusting the inclination angle including the end of each inclined portion. The direction can be adjusted.
As a material of the reflector, a thin metal plate formed by a silver mirror treatment on the reflecting surface, a semi-transparent or opaque plastic plate laminated with a metal vapor deposition treatment such as aluminum or aluminum foil, a paper plate, etc. are applied. Can do. The thickness of the reflecting plate is not particularly limited as long as it can be bent into a circumferential shape and can retain the shape as the inclined portion of the reflecting shade, but for example, a metal such as aluminum or a surface-treated steel plate In the case of a plate, 0.2 mm to 2 mm is preferable because it is lightweight, easy to process, and easily available.
固定プレートは、２段以上からなる上下の傾斜部を、その背面側（外側）から固定する複数の帯板部材であり、反射笠の軸方向すなわち傾斜部の周方向と直角方向に伸延するとともに、上下の傾斜部の背面の形状に合わせて屈曲させて形成されている。
反射笠の周方向で見た場合、固定プレートの取り付け位置は対称に配置するのが、笠の形状保持の観点で好ましく、反射板の周方向接合箇所を含む２〜８ヶ所が好適である。反射板を周方向接合箇所以外の周方向位置でも固定プレートで固定することにより、反射笠の形状保持が容易となる場合があり、特に反射板の板厚が薄いときに好適である。
The fixing plate is a plurality of strip plate members that fix the upper and lower inclined portions composed of two or more steps from the back side (outside), and extend in the direction perpendicular to the axial direction of the reflective shade, that is, the circumferential direction of the inclined portion. The upper and lower inclined portions are formed to be bent in accordance with the shape of the back surface.
When viewed in the circumferential direction of the reflective shade, it is preferable to place the fixing plate symmetrically from the viewpoint of maintaining the shape of the shade, and 2 to 8 locations including the location of the reflective plate in the circumferential direction are suitable. By fixing the reflecting plate with a fixing plate even at a circumferential position other than the circumferential joining point, the shape of the reflecting shade may be easily maintained, which is particularly suitable when the thickness of the reflecting plate is thin.
このような固定プレートの材質としては、アルミニウム板、表面処理鋼板などの金属板、プラスチック板などが挙げられる。帯板の板厚としては、特に限定はされないが１ｍｍ〜３ｍｍが、軽量かつ加工がしやすく入手も容易なので好適である。固定プレートへの反射板の固定には、リベット、接着剤、粘着材など公知の方法を用いることができる。 Examples of the material of the fixing plate include an aluminum plate, a metal plate such as a surface-treated steel plate, and a plastic plate. The thickness of the band plate is not particularly limited, but 1 mm to 3 mm is preferable because it is lightweight, easy to process, and easily available. For fixing the reflection plate to the fixing plate, a known method such as a rivet, an adhesive or an adhesive can be used.
さらに、本実施形態の照明器具の反射笠においては、互いに隣接する各傾斜部には、上側となる傾斜部の下端が下側の傾斜部の上端の外側に突出して配置されるか、又は逆に下側となる傾斜部の上端が上側の傾斜部の下端の外側に突出して配置され、且つ、傾斜部の傾斜角度を固定調整する配光制御部を固定プレートに係合するように、各反射板の端部に切り欠き状に設けることができる。これによって、配光制御部の位置を調整して各傾斜部の傾斜角度を設定し、固定プレートに各傾斜部を固定支持することができる。 Furthermore, in the reflective shade of the lighting fixture of the present embodiment, the lower ends of the upper inclined portions are arranged on the inclined portions adjacent to each other so as to protrude outside the upper ends of the lower inclined portions, or vice versa. The upper end of the lower inclined portion is arranged so as to protrude outward from the lower end of the upper inclined portion, and the light distribution control unit for fixing and adjusting the inclination angle of the inclined portion is engaged with the fixing plate. It can be provided in a cutout shape at the end of the reflector. Thus, the position of the light distribution control unit is adjusted to set the inclination angle of each inclined part, and each inclined part can be fixedly supported on the fixed plate.
配光制御部は、例えば、略扇状をなす反射板の周縁に切り欠き状や突起状に固定プレートの数に応じて単数又は複数設けられる部分であり、一枚の反射板に複数の配光制御部を設けておきその中から所定の傾斜角度になるように選択して反射板の端面同士を周状に連結して形成することもできる。こうして、異なった傾斜角度を有した複数の傾斜部を固定プレートに固定して反射笠としている。ここで、異なった傾斜角度を有した複数の傾斜部とは、反射笠の軸線方向に対して各傾斜部の傾斜角度が異なっていることをいう。
なお、配光制御部は、これを反射板に設けずに固定プレートに設けることもできる。この場合、固定プレートは上下の隣接する反射板の接合線よりの伸延した位置で屈曲させ、隣接する傾斜部の突出した反射板端部が反射板の中央部と同じ傾斜角度を維持できるようになっている。
The light distribution control unit is, for example, a portion provided in the periphery of the substantially fan-shaped reflection plate in a cutout shape or a projection shape according to the number of fixed plates, or a plurality of light distributions on one reflection plate. It is also possible to provide a control unit and select it so as to have a predetermined inclination angle, and connect the end faces of the reflectors in a circumferential shape. In this way, a plurality of inclined portions having different inclination angles are fixed to the fixed plate to form a reflective shade. Here, the plurality of inclined portions having different inclination angles means that the inclination angles of the respective inclined portions are different with respect to the axial direction of the reflective shade.
The light distribution control unit can also be provided on the fixed plate without providing it on the reflecting plate. In this case, the fixed plate is bent at a position extending from the joining line of the upper and lower adjacent reflectors so that the protruding reflector end of the adjacent inclined part can maintain the same inclination angle as the central part of the reflector. It has become.
本実施形態の照明器具の反射笠において、２枚の反射板の端部を連結することにより、反射笠の各傾斜部は周方向に屈曲部のない円錐形状とすることができる。これによって、傾斜部が多角錐状ではなく円錐状なので、照明の周方向の均一性を高めることができる。
なお、２枚の反射板に代えて多数枚の反射板を連結して１段の傾斜部とすることもできる。傾斜部が多角錐台状となる場合に好適である。
In the reflective shade of the lighting fixture of the present embodiment, by connecting the ends of the two reflectors, each inclined portion of the reflective shade can be formed into a conical shape having no bent portion in the circumferential direction. Thereby, since the inclined portion is not a polygonal pyramid but a conical shape, the uniformity in the circumferential direction of illumination can be improved.
In addition, it can replace with two reflectors and can also make a 1 step | paragraph inclined part by connecting many reflectors. This is suitable when the inclined portion has a polygonal frustum shape.
本実施形態の照明器具の反射笠は、傾斜部の内面に高反射率の鏡面処理、例えば、亜鉛めっき鋼板などの表面処理金属板やアルミニウム合金薄板上に銀めっきを施した、いわゆる銀鏡めっき（銀鏡処理）を施した金属板で構成することもできる。これによって、高い反射率の反射笠を実現することができる。 The reflective shade of the lighting fixture of the present embodiment is a so-called silver mirror plating (in which the inner surface of the inclined portion is subjected to high-reflectance mirror treatment, for example, a surface-treated metal plate such as a galvanized steel plate or an aluminum alloy thin plate is plated with silver. It can also be composed of a metal plate subjected to silver mirror treatment. As a result, a reflective shade having a high reflectance can be realized.

In addition, in the exploded assembly explanatory view of FIG. 3A, only the front two of the four belt-like fixing plates 14 are shown.
This will be described with reference to enlarged explanatory views (FIGS. 4B to 4D) of the reflector fixing plate mounting portion in the inclined portion shown in FIG. Here, it arrange | positions so that the lower end of the inclination part 11 used as the upper side may cover the outer side of the upper end of the inclination part 12 used as the lower side (FIG.4 (c)), and functions as a light distribution control part at the lower end of an inclination part A notch 15 is provided. Thus, the inclined portions 11 to 13 are engaged with the fixed plate 14 and the inclination angle of the inclined portion 11 is fixedly adjusted (FIG. 4D).
なお、図４（ｃ）、図４（ｄ）において反射板接合線Ｓとは、下側傾斜部１２の上端である。また実施例では、反射板として銀鏡めっき処理した板厚０．６ｍｍのＪＩＳ５０５２−Ｈ３２のアルミニウム合金板を用い、反射笠の寸法は、最大外径（下端）５８３ｍｍ、高さ（ランプホルダを除いた笠部分のみ）２９９ｍｍ、α１＝４７°、α２＝３１°、α３＝１６．５°である。固定プレートの帯板として、幅＝３０ｍｍ、板厚＝１．６ｍｍのＪＩＳ５０５２−Ｈ３２のアルミニウム合金板を用いた。 In FIG. 4C and FIG. 4D, the reflecting plate bonding line S is the upper end of the lower inclined portion 12. Further, in the examples, a JIS5052-H32 aluminum alloy plate having a thickness of 0.6 mm subjected to silver mirror plating treatment was used as the reflecting plate, and the dimensions of the reflecting shade were a maximum outer diameter (lower end) of 583 mm and a height (excluding the lamp holder). Only the shade portion) 299 mm, α1 = 47 °, α2 = 31 °, α3 = 16.5 °. As a band plate of the fixed plate, a JIS5052-H32 aluminum alloy plate having a width = 30 mm and a plate thickness = 1.6 mm was used.
図５に示すように、傾斜部１１は、それぞれ扇状の２枚の反射板１１ａにおける片側及び固定プレート１４ａに設けられているリベット穴１６にリベット１７を通して、まずは２枚の反射板の片側（図５の右側）を固定プレート１４ａに固定する。
その後、反射板１１ａの他方側（図５の左側）をもう一つ固定プレート１４ｂのリベット穴１６に引き寄せてリベット１７を通して固定プレート１４ｂに固定することにより曲面を形成し、円錐台形状とする。
次に、切欠部１５において固定プレート１４ａ、１４ｂを予め所定角度で下方に屈曲させておき、下側となる傾斜部１２を同様にして形成する。
このようにして、３段の傾斜部１１，１２，１３を備え固定プレート１４によって支持固定された反射笠を完成させる。
As shown in FIG. 5, the inclined part 11 passes through a rivet 17 through one side of the two fan-shaped reflectors 11a and a rivet hole 16 provided in the fixed plate 14a. 5) is fixed to the fixing plate 14a.
Thereafter, the other side (the left side in FIG. 5) of the reflecting plate 11a is drawn to the rivet hole 16 of the other fixing plate 14b and fixed to the fixing plate 14b through the rivet 17, thereby forming a curved surface to have a truncated cone shape.
Next, the fixing plates 14a and 14b are bent downward at a predetermined angle in the notch 15 in advance, and the lower inclined portion 12 is formed in the same manner.
In this way, a reflective shade that is provided with three stages of inclined portions 11, 12, 13 and is supported and fixed by the fixing plate 14 is completed.
図６に実施例１の反射笠１０について、外形・高さ寸法がほぼ同等で傾斜段部を有さない単純な椀状反射笠（内面アルミ蒸着鏡面）を比較例として、同じランプ（岩崎電気（株）製Ｍ３６０ＦＣＥＬＳＰ−Ｗ／ＢＵＤ）を用い、１１ｍの高さから照らしたときの床上１ｍでの照度分布を示す。実施例１の反射笠１０ではその中央付近（床中心から約３〜４ｍの円形範囲内）での照度が約３５０ｌｘであり、比較例の反射笠が約２６０ｌｘであるのに比べ、照明効率の高いことがわかる。 FIG. 6 shows the same lamp (Iwasaki Electric Co., Ltd.) as a comparative example with respect to the reflective shade 10 of Example 1 as a comparative example using a simple saddle-shaped reflective shade (inner surface aluminum-deposited mirror surface) having substantially the same outer shape and height and no inclined stepped portion. Illuminance distribution at 1 m on the floor when illuminated from a height of 11 m using M360FCELSP-W / BUD manufactured by Co., Ltd. is shown. In the reflective shade 10 of Example 1, the illuminance near the center (in a circular range of about 3 to 4 m from the floor center) is about 350 lx, and the illumination efficiency of the comparative example is about 260 lx. I understand that it is expensive.
実施例２の照明器具の反射笠２０は、図７（ａ）（ｂ）に示すように、上側の傾斜部２１の下端が下側の傾斜部２２の上端を覆い被さるように突出して配置されている点では実施例１の反射笠と同様であるが、図７（ａ）に示すように配光制御部２５が固定プレート２４に設けられ、傾斜部２１、２２を形成する各反射板２１ａ，２２ａの周端部には固定プレートに係合する配光制御部が設けられていない点で異なる。
この場合、固定プレートの帯板を上下の隣接する反射板の接合線Ｓよりの伸延した位置で屈曲させ突出した端部を軸方向に曲げないように収容可能とすることにより、隣接する傾斜部の突出した反射板端部が反射板の中央部と同じ傾斜角を維持できるようになっている。
このように固定プレートに反射板の突出部が係合する配光制御部２５を設けることで、円錐台状となる各傾斜部２１、２２の傾斜角度を端部まで含めて調整することができ、反射板の固定方法を調整することにより配光制御が可能となり、消費電力を増やすことなく照度を向上でき照明器具の器具効率向上が図れる。
As shown in FIGS. 7A and 7B, the reflecting shade 20 of the lighting fixture of the second embodiment is disposed so as to protrude so that the lower end of the upper inclined portion 21 covers the upper end of the lower inclined portion 22. However, as shown in FIG. 7A, the light distribution control unit 25 is provided on the fixed plate 24, and each of the reflection plates 21a forming the inclined portions 21 and 22 is the same as the reflection shade of the first embodiment. , 22a is different in that a light distribution control section that engages with the fixed plate is not provided at the peripheral end of 22a.
In this case, the band plate of the fixed plate is bent at a position extending from the joint line S of the upper and lower adjacent reflectors, and the protruding end can be accommodated so as not to be bent in the axial direction. The protruding reflector end can maintain the same inclination angle as the central part of the reflector.
In this way, by providing the light distribution control unit 25 in which the protruding portion of the reflecting plate engages with the fixed plate, the inclination angle of each of the inclined parts 21 and 22 having a truncated cone shape can be adjusted including the end part. The light distribution can be controlled by adjusting the fixing method of the reflecting plate, the illuminance can be improved without increasing the power consumption, and the efficiency of the lighting fixture can be improved.
本発明の照明器具の反射笠は、天井に取り付けられるダウンライト照明用としてだけでなく、建物の壁面や床面に取り付ける照明器具用としても利用でき、産業上の利用可能性が極めて高い。 The reflective shade of the lighting fixture of the present invention can be used not only for downlight lighting attached to the ceiling but also for lighting fixtures attached to the wall surface or floor surface of a building, and has very high industrial applicability.
