Description

Translated fromJapanese

本発明は、照明カバーを備えた照明器具に関する。  The present invention relates to a lighting fixture including a lighting cover.

照明器具において、光源となるランプを露出させている場合や、ランプを透明の照明カバーで覆っている場合には、点灯時にランプを作業面側から直視するとグレアを生じて不快感を与えるうといった問題や、非点灯時にもランプが作業面側から視認されるので意匠性が低くなるといった問題がある。これに対して、図3に概略的に示すように、光源となるランプ1を設置した照明器具本体2に、シボ加工等の拡散処理を施した照明カバー3を備えてランプ1を覆うようにした照明器具が、従来から提案されている(例えば特許文献1参照)。このように拡散処理を施した照明カバー3を備えておけば、点灯時にランプ1を作業面20側から視たときも、拡散処理された照明カバー3を通じてランプ1を視ることになるのでグレアを生じることがなく、また、非点灯時にはランプ1が作業面20側から視認され難くなるので意匠性は良好に保持される。  In lighting fixtures, when the lamp that is the light source is exposed, or when the lamp is covered with a transparent lighting cover, glare occurs when the lamp is directly viewed from the work surface side when it is lit, which may cause discomfort. There is a problem or a problem that the design is lowered because the lamp is visually recognized from the work surface side even when the lamp is not lit. On the other hand, as schematically shown in FIG. 3, the luminairemain body 2 provided with thelamp 1 serving as a light source is provided with alighting cover 3 that has been subjected to diffusion processing such as embossing so as to cover thelamp 1. The lighting fixture which was made is proposed conventionally (for example, refer patent document 1). If theillumination cover 3 subjected to the diffusion treatment is provided in this way, thelamp 1 can be seen through theillumination cover 3 subjected to the diffusion treatment even when thelamp 1 is viewed from thework surface 20 side when it is turned on. In addition, when the lamp is not lit, thelamp 1 becomes difficult to be visually recognized from thework surface 20 side.

ところが、上記の拡散処理された照明カバー3を備えただけの照明器具にあっては、以下の問題が生じる。つまり、点灯時にランプ1から照射されるランプ光の全てが照明カバー3を透過する際に拡散処理されるため、透過損失による全体の光量ロスが大きくなり、しかも拡散処理された光は全体に広がるので、作業面20を効率的に照明することができないという問題である。
特開2006−294352号公報
However, the following problem arises in the luminaire simply having the diffusingillumination cover 3 described above. That is, since all of the lamp light emitted from thelamp 1 when lit is transmitted through theillumination cover 3, the entire light amount loss due to transmission loss is increased, and the light subjected to the diffusion process spreads throughout. As a result, thework surface 20 cannot be efficiently illuminated.
JP 2006-294352 A

本発明は上記問題点に鑑みて発明したものであって、ランプを直視することによるグレアを防止しながら、ランプの光量を有効に利用して作業面を明るく照らすことの可能な照明器具を提供することを、課題とするものである。  The present invention has been invented in view of the above problems, and provides a luminaire capable of brightly illuminating a work surface by effectively using the amount of light of a lamp while preventing glare from directly viewing the lamp. It is a task to do.

上記課題を解決するために本発明を、光源となるランプ1を設置した照明器具本体2と、ランプ1を覆う照明カバー3とを具備し、照明カバー3を透過して照射されるランプ光で作業面20を照らす照明器具において、照明カバー3のうち、ランプ1と作業面20の間に位置する中央部分を拡散部7とし、該拡散部7を囲む周縁部分を透明部8とすると共に、透明部8を透過したランプ光を作業面20に向けて集光するリフレクタ9を備えたものとする。  In order to solve the above-mentioned problems, the present invention is based on lamp light that includes a luminairemain body 2 provided with alamp 1 serving as a light source and anillumination cover 3 that covers thelamp 1 and is irradiated through theillumination cover 3. In the lighting fixture that illuminates thework surface 20, the center portion located between thelamp 1 and thework surface 20 in thelighting cover 3 is thediffusion portion 7, and the peripheral portion surrounding thediffusion portion 7 is thetransparent portion 8, It is assumed that areflector 9 that condenses the lamp light transmitted through thetransparent portion 8 toward thework surface 20 is provided.

上記構成の照明器具にあっては、ランプ1から放出されるランプ光は照明カバー3の拡散部7を通じて作業面20側に直接照射されるので、作業面20側の使用者がランプ1を直視してグレアを生じるといった事態は防止される。しかも、この透過率が小さく且つ指向性の低い拡散部7は照明カバー3の中央部分に限定し、他の周縁部分は透過率が大きく且つ指向性の高い透明部8とし、この透明部8を透過したランプ光はリフレクタ9を介して作業面20側に集光されるように設けているので、全体の光量を極力ロスすることなく、作業面20を効率的に照明することが可能となっている。  In the lighting fixture having the above configuration, the lamp light emitted from thelamp 1 is directly irradiated to thework surface 20 side through thediffusion portion 7 of thelighting cover 3, so that the user on thework surface 20 side looks directly at thelamp 1. This prevents the occurrence of glare. In addition, thediffuser 7 having a low transmittance and low directivity is limited to the central portion of theillumination cover 3, and the other peripheral portion is atransparent portion 8 having a high transmittance and high directivity. Since the transmitted lamp light is provided so as to be condensed on thework surface 20 side via thereflector 9, it is possible to efficiently illuminate thework surface 20 without losing the entire amount of light as much as possible. ing.

また、上記リフレクタ9は、ランプ1を視認することが可能な作業面20側の領域を、照明カバー3の拡散部7を通じてのみランプ1が視認可能な領域に規制するものであることが好適である。このようにすることで、作業面20側の使用者がランプ1を直視してグレアを生じるといった事態が更に確実に防止される。  Thereflector 9 preferably restricts the area on thework surface 20 side where thelamp 1 can be visually recognized to an area where thelamp 1 is visible only through thediffusion portion 7 of theillumination cover 3. is there. By doing in this way, the situation where the user by the side of thework surface 20 looks at the lamp |ramp 1 and a glare is produced | generated more reliably is prevented.

請求項1に係る発明は、ランプを直視することによるグレアを防止しながら、ランプの光量を有効に利用して作業面を明るく照らすことができるという効果を奏する。  The invention according toclaim 1 has an effect that the work surface can be brightly illuminated by effectively using the light quantity of the lamp while preventing glare due to direct viewing of the lamp.

また請求項2に係る発明は、請求項1に係る発明の効果に加えて、更に確実にグレアを防止することができるという効果を奏する。  In addition to the effect of the invention according toclaim 1, the invention according toclaim 2 has an effect that glare can be more reliably prevented.

以下、本発明を添付図面に示す実施形態に基づいて説明する。なお、図3に示した従来例と同様の構成については同一符号を付して、重複する説明は省略する。図1、図2には、本発明の実施形態における一例の照明器具を示している。本例の照明器具は、作業面20を上方から照明するためのダウンライトであり、具体的には、居室空間内の流し元を作業面とする流し元灯として、好適に用いられる。  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In addition, the same code | symbol is attached | subjected about the structure similar to the prior art example shown in FIG. 3, and the overlapping description is abbreviate | omitted. 1 and 2 show an example of a lighting fixture according to an embodiment of the present invention. The luminaire of this example is a downlight for illuminating thework surface 20 from above, and specifically, is suitably used as a sink light that uses the sink in the living room space as the work surface.

本例においては、照明器具本体2の下面として円形状に形成される平坦なランプ設置面4に、LEDから成るランプ1を複数個(図示例では四つ)設置している。各ランプ1の配置は、ランプ設置面4の外縁から一定幅だけ内側に描かれる円周上において、周方向に等間隔を隔てた箇所となっている(図2参照)。  In this example, a plurality (four in the illustrated example) oflamps 1 made of LEDs are installed on a flatlamp installation surface 4 formed in a circular shape as the lower surface of the luminairemain body 2. Thelamps 1 are arranged at equal intervals in the circumferential direction on a circumference drawn by a certain width from the outer edge of the lamp installation surface 4 (see FIG. 2).

照明器具本体2の下側には、ランプ設置面4との間で全てのランプ1を囲む有底筒状の照明カバー3が取り付けてある。この照明カバー3は、円板状を成す底壁部5と、この底壁部5の外周縁から上方に延設される円筒状の側壁部6から成る。照明カバー3のうち底壁部5にはシボ加工を施してあり、透過する光が拡散するようになっている。また照明カバー3のうち側壁部6にはシボ加工等の拡散処理は施してなく、光が拡散することなく高効率で透過するようになっている。即ち本例にあっては、照明カバー3のうちで各ランプ1とその下方の作業面20との間に位置する中央部分を成す底壁部5が、透過率が小さく且つ指向性の低い拡散部7となり、照明カバー3のうちで該拡散部7を囲む周縁部分を成す側壁部6が、透過率が大きく且つ指向性の高い透明部8となる構造である。  A bottomedcylindrical lighting cover 3 that surrounds all thelamps 1 with thelamp installation surface 4 is attached to the lower side of thelighting fixture body 2. Thelighting cover 3 includes abottom wall portion 5 having a disk shape and a cylindricalside wall portion 6 extending upward from the outer peripheral edge of thebottom wall portion 5. Thebottom wall portion 5 of theillumination cover 3 is subjected to a textured process so that transmitted light is diffused. Further, theside wall portion 6 of thelighting cover 3 is not subjected to diffusion processing such as embossing, and light is transmitted with high efficiency without being diffused. That is, in this example, thebottom wall portion 5 forming the central portion located between eachlamp 1 and thework surface 20 below thelamp cover 3 in theillumination cover 3 has a low transmittance and a low directivity. Theside wall part 6 which becomes thepart 7 and forms the peripheral part surrounding thediffusion part 7 in theillumination cover 3 has a structure that becomes atransparent part 8 having a high transmittance and high directivity.

更に照明器具本体2の照明カバー3を囲む位置には、照明カバー3の透明な側壁部6を透過したランプ光を反射させて下方の作業面20に集光させるためのリフレクタ9を装着させている。このリフレクタ9は、ランプ1及び照明カバー3から作業面20側に(即ち下方に)向けて離れるほど内径が漸次大きくなるように形成したスカート状の部材であり、その内周面が反射面10となっている。  Further, areflector 9 for reflecting the lamp light transmitted through thetransparent side wall 6 of thelighting cover 3 and condensing it on thelower work surface 20 is attached to a position surrounding thelighting cover 3 of thelighting fixture body 2. Yes. Thereflector 9 is a skirt-like member formed so that its inner diameter gradually increases as it moves away from thelamp 1 and theillumination cover 3 toward the work surface 20 (that is, downward), and its inner peripheral surface has a reflectingsurface 10. It has become.

リフレクタ9の作業面20側を向いて開口する開口縁11は、照明カバー3の底壁部5よりも作業面20側に大きく突出した形状になっている。図1に位置関係を概略的に示すように、この開口縁11上の点と照明カバー3の底壁部5の端縁上の点とを結ぶ直線Lを描いたとき、該直線Lの内側に位置するように各ランプ1を配置させているので、作業面20側に位置する使用者からすればリフレクタ9が遮蔽板となり、照明カバー3のうち拡散処理を施した底壁部5を通じてしか各ランプ1を視認することができない構造となっている。換言すれば、上記リフレクタ9は透明な側壁部6を通じて側方に透過されるランプ光を下方に集光させる部材として機能すると共に、各ランプ1を視認することが可能な作業面20側の領域を、照明カバー3の拡散部7を通じてのみランプ1が視認可能な領域(図中の直線Lの内側の領域)に規制する部材としても、機能する。なお、図示例では各ランプ1の全部が直線Lの内側に位置するように配置しているが、各ランプ1の一部のみが直線Lの外側に位置する配置としてもよい。  Theopening edge 11 that opens toward thework surface 20 side of thereflector 9 has a shape that protrudes larger toward thework surface 20 side than thebottom wall portion 5 of thelighting cover 3. As schematically shown in FIG. 1, when a straight line L connecting the point on theopening edge 11 and the point on the edge of thebottom wall portion 5 of thelighting cover 3 is drawn, the inside of the straight line L is drawn. Since thelamps 1 are arranged so as to be positioned at the position of thework surface 20, thereflector 9 serves as a shielding plate for the user located on thework surface 20 side, and only through thebottom wall portion 5 subjected to the diffusion treatment in thelighting cover 3. Eachlamp 1 cannot be visually recognized. In other words, thereflector 9 functions as a member for condensing the lamp light transmitted laterally through thetransparent side wall 6 downward, and is an area on thework surface 20 side where eachlamp 1 can be visually recognized. It functions also as a member which restrict | limits to the area | region (area | region inside the straight line L in a figure) which the lamp |ramp 1 can visually recognize only through the spreading |diffusion part 7 of theillumination cover 3. FIG. In the illustrated example, all thelamps 1 are arranged so as to be located inside the straight line L, but only a part of eachlamp 1 may be arranged outside the straight line L.

上記構成の照明器具とすることで、各ランプ1のランプ光は照明カバー3の拡散部7を通じて作業面20側に直接照射されることとなり、作業面20側の使用者がランプ1を直視してグレアを生じるといった事態が防止される。しかも、この透過率が小さく且つ指向性の低い拡散部分は照明カバー3のうち底壁部5に限定し、他の部分つまり側壁部6は透過率が大きく且つ指向性の高い透明部分とし、この透明部分を透過して側方に照射されたランプ光はリフレクタ9を介して作業面20の主に周縁部分に集光されるように設けているので、光量を極力ロスすることなく、作業面20を効率的に照明することが可能となっている。  With the lighting fixture having the above-described configuration, the lamp light of eachlamp 1 is directly irradiated to thework surface 20 side through thediffusion portion 7 of thelighting cover 3, and the user on thework surface 20 side looks directly at thelamp 1. This prevents the occurrence of glare. In addition, the diffusion portion having a low transmittance and low directivity is limited to thebottom wall portion 5 of thelighting cover 3, and the other portion, that is, theside wall portion 6, is a transparent portion having a high transmittance and high directivity. Since the lamp light transmitted through the transparent portion and irradiated to the side is provided so as to be condensed mainly on the peripheral portion of thework surface 20 via thereflector 9, the work surface can be obtained without losing the amount of light as much as possible. 20 can be efficiently illuminated.

なお、照明カバー3の底壁部5の拡散処理はシボ加工には限定されず、透過するランプ光を拡散させる処理であれば、他の手段であっても構わない。またランプ1についてもLEDには限定されず、蛍光灯等のいずれを用いてもよい。ただし本例の構造は、蛍光灯と比較して輝度は高いが光量の少ないLEDを用いてLED照明器具とした場合に、特に相性の良い構造である。更に、本例の構造はダウンライトに限定されず、光源となるランプ1、作業面20、作業者視点の位置が図1に示すような関係となる照明器具であれば、問題なく適用可能である。  Note that the diffusion process of thebottom wall portion 5 of theillumination cover 3 is not limited to the embossing process, and other means may be used as long as the process diffuses the transmitted lamp light. Further, thelamp 1 is not limited to the LED, and any fluorescent lamp or the like may be used. However, the structure of this example is a structure that is particularly compatible with an LED lighting apparatus using an LED that has a high luminance but a small amount of light compared to a fluorescent lamp. Furthermore, the structure of the present example is not limited to a downlight, and can be applied without any problem as long as thelamp 1 as a light source, thework surface 20, and the position of the worker's viewpoint are in the relationship as shown in FIG. is there.
