Description
【発明の詳細な説明】 〔発明の属する技術分野〕 本発明はルーバーを有する照明器具に関する。Description: TECHNICAL FIELD The present invention relates to a lighting fixture having a louver.
従来、この種の照明器具は実開昭59−76012号公報
（文献１）および特願平３−34204号公報（文献２）等
に開示されている。Conventionally, this type of lighting fixture is disclosed in Japanese Utility Model Laid-Open No. 59-76012 (Document 1) and Japanese Patent Application No. 3-34204 (Document 2).
文献１および２の照明器具は、側壁部を有する器具本
体、この器具本体内に配設されるルーバーおよびルーバ
ーを支持するルーバー枠で構成されている。The lighting fixtures of Literatures 1 and 2 each include a fixture main body having a side wall, a louver provided in the fixture main body, and a louver frame supporting the louver.
ルーバーは、その軸方向に沿って延びる縦ルーバー羽
根と、これに直交する複数の横ルーバー羽根とを格子状
に組み合わせて構成されている。ルーバー枠は、全体が
ルーバー枠とは別部品で形成されたルーバーのその内周
に載置するかマグネットで接合させて支持している。The louver is configured by combining a vertical louver blade extending along the axial direction thereof and a plurality of horizontal louver blades orthogonal to the vertical louver blade in a lattice shape. The louver frame is supported by being mounted on the inner periphery of a louver formed entirely of a separate component from the louver frame or joined with a magnet.
また、実開昭52−66180号公報（文献３）に開示の照

他端には固定ネジが配設されている。そして、器具本体
の軸受けにルーバーの軸を装着するとともに固定ネジを
器具本体の固定部にねじ込むことによってルーバーが器
具本体に装着される。Further, in the lighting fixture disclosed in Japanese Utility Model Laid-Open No. 52-66180 (Reference 3), a bearing plate and a fixing portion are provided inside the opening of the fixture main body. Also, a shaft at one end of the louver,
A fixing screw is provided at the other end. Then, the louver is mounted on the device main body by mounting the louver shaft on the bearing of the device main body and screwing the fixing screw into the fixing portion of the device main body.
この構造によると、ルーバーは軸を支点に回動自在に
なるので、器具本体内に配設されたランプを交換すると
きには、ルーバー全体を器具本体から取り外さないでラ
ンプ交換を容易にすることができるものである。According to this structure, the louver is rotatable about the axis, so that when replacing the lamp provided in the appliance body, the lamp can be easily replaced without removing the entire louver from the appliance body. Things.
しかしながら、文献１および２のルーパー枠は器具本
体の側壁部間の幅寸法よりも大きい寸法であるので、器
具本体を小形化してもルーバーを含めた器具全体の幅寸
法が大きくなる欠点がある。また、ルーバー枠は、側壁
部の端面に重ねて取り付けられているので、ルーバー枠
の高さ分、器具全体の高さが高くなる欠点もある。However, since the looper frames of Literatures 1 and 2 are larger than the width between the side walls of the instrument main body, there is a drawback that the width of the entire instrument including the louver becomes large even if the instrument main body is downsized. In addition, since the louver frame is mounted on the end face of the side wall portion, there is a disadvantage that the height of the entire device is increased by the height of the louver frame.
また、ルーバーとルーバー枠は別部品で形成され、ル
ーバーはルーバー枠の内周に形成されたルーバー受け片
に載置等して支持されているので、ルーバーが載置され
る部分の面積分、器具本体の下面開口面積が減少する。In addition, the louver and the louver frame are formed of separate parts, and the louver is supported by being mounted on a louver receiving piece formed on the inner periphery of the louver frame. The lower opening area of the instrument body is reduced.
また、ルーバーとルーバー枠は別部品で形成されてい
るので、ルーバー枠にルーバーを装着するのに別部品が
必要になり、その分、組立時間およびコストが増加する
恐れもある。In addition, since the louver and the louver frame are formed of different components, separate components are required to mount the louver on the louver frame, which may increase assembling time and cost.
さらにまた、文献３にはルーバー枠はなく、同心円状

を構成している。この場合には、ルーバー構体の強度が
弱く、またランプを収納する器具本体内面とルーバー構
体との間に隙間ができやすくなり、この部分から不用意
な光が漏れる恐れも出てくる。Furthermore, there is no louver frame in Literature 3, and a louver structure is configured by fixing louver blades arranged concentrically by a shaft. In this case, the strength of the louver structure is weak, and a gap is easily formed between the inner surface of the fixture housing the lamp and the louver structure, and there is a risk that careless light may leak from this portion.
本発明は、器具本体にルーバー構体を配設しても器具
高さおよび幅を大きくすることなく、さらにルーバー構
体の強度向上と光漏れを生じにくい照明器具を提供する
ことを目的とする。An object of the present invention is to provide a lighting device that does not increase the height and width of the louver structure even when the louver structure is provided in the device main body, further improves the strength of the louver structure, and hardly causes light leakage.

体の強度を向上できる。[Effects of the Invention] As described above, according to the first aspect of the present invention, the louver structure is disposed close to the side plate portion of the device main body, and the end surface of the frame portion of the louver structure is substantially the same as the end surface of the bent portion of the device main body. Since it is arranged so as to be on the surface, the height and width of the entire device are suppressed from increasing, and light leakage from the device main body is less likely to occur. Further, the frame portion can improve the strength of the louver structure. Furthermore, since the louver structure is rotatable about the engagement mechanism as a fulcrum, it is possible to replace the fluorescent lamp provided in the instrument body without removing the louver structure from the instrument body. Claim 2
According to the present invention, in addition to the effect of the first aspect of the present invention, the top plate constituting the instrument main body can block dust and dirt from the ceiling. According to the third aspect of the invention, in addition to the first or second aspect, the frame portion can be reinforced and the strength of the louver structure can be improved.
