Description

本発明は、ダウンライト等に使用される照明器具に関するものである。   The present invention relates to a lighting fixture used for a downlight or the like.

一般に、高輝度放電灯(HIDランプ)は、白熱灯や蛍光灯に比較してエネルギ効率が高く、高輝度が得られ、また消費電力が少なくて寿命が長いといった利点があり、近年、路面などの大規模空間を照明するダウンライトなどに使用される頻度が多くなっている。   In general, high-intensity discharge lamps (HID lamps) have the advantages of higher energy efficiency and higher luminance than incandescent lamps and fluorescent lamps, as well as low power consumption and long life. It is frequently used for downlights that illuminate large-scale spaces.

ところで、このような照明器具は、発光源となるランプがソケットに装着されて電気的かつ機械的な接続が図られるが、このような照明器具が例えば道路に近接した建造物に設置されるような場合や、エレベータのような移動体に設置されるような場合には、振動等に起因してランプの装着状態に緩みが生じて、ランプがソケットから外れてしまうことがある。   By the way, in such a lighting fixture, a lamp serving as a light source is mounted on a socket to achieve electrical and mechanical connection. However, such a lighting fixture may be installed in a building close to a road, for example. In other cases, or when installed in a moving body such as an elevator, the lamp may be loosely mounted due to vibration or the like, and the lamp may come off the socket.

このようなランプのソケットからの緩みを防止するために、従来技術では、嵌合緩み防止手段としてソケットの内周面に板バネを設け、ランプの口金をソケットにねじ込むと、板バネが口金の外周部を押圧することで緩み防止を図るようにしたものが提案されている(例えば、下記の特許文献1参照)。
特開平11−329763号公報
In order to prevent such loosening of the lamp from the socket, in the prior art, a leaf spring is provided on the inner peripheral surface of the socket as means for preventing loosening of fitting, and when the lamp base is screwed into the socket, the leaf spring is connected to the base. The thing which aimed at prevention of loosening by pressing an outer peripheral part is proposed (for example, refer the following patent document 1).
JP-A-11-329963

しかしながら、上記の特許文献1記載のものでは、ランプの口金をソケットにねじ込むと、板バネが口金の外周部を押圧するだけの極めて簡単な構造であるため、長期使用中には、依然として振動等に起因してランプの口金がソケットから緩んで外れてしまい、ランプが路上等に落下する恐れがあり、緩み防止対策として十全ではない。   However, in the above-described Patent Document 1, when the lamp base is screwed into the socket, the leaf spring has a very simple structure that only presses the outer periphery of the base. As a result, the base of the lamp may come loose from the socket and come off, and the lamp may fall onto the road or the like.

本発明は、上記の課題を解決するためになされたもので、長期使用中に振動等に起因してランプの口金がソケットから緩んで外れてしまって落下するなどの不具合発生を一層確実に防止することができる照明器具を提供することを目的とする。   The present invention has been made to solve the above problems, and more reliably prevent the occurrence of problems such as the lamp base loosening and coming off from the socket and falling due to vibration during long-term use. It is an object of the present invention to provide a lighting device that can be used.

上記の目的を達成するために、本発明の照明器具にあっては、直管形のランプと、ランプ取付用のソケットとを有し、前記ランプは、前記ソケットに挿着される口金と、発光部となるバルブと、前記口金とバルブ間を接続する台座とが設けられる一方、建造物に固定されて前記ソケットを覆うソケットカバー受けと、このソケットカバー受けに装着されるソケットカバーとを備え、前記ソケットカバーには、前記バルブの外径よりも大径で、かつ、前記台座の外径よりも小径のバルブ挿通孔が形成されている。   In order to achieve the above object, the lighting apparatus of the present invention has a straight tube lamp and a socket for mounting the lamp, and the lamp includes a base inserted into the socket, A bulb serving as a light emitting unit, a base connecting the base and the bulb are provided, a socket cover receiver fixed to a building and covering the socket, and a socket cover attached to the socket cover receiver. The socket cover is formed with a valve insertion hole having a diameter larger than the outer diameter of the valve and smaller than the outer diameter of the pedestal.

本発明の照明器具においては、ランプの口金がソケットに装着されるだけでなく、さらに、ソケットカバーがソケットカバー受けに装着されるので、長期使用中に振動等に起因してランプの口金がソケットから緩んで外れても、ランプの台座がソケットカバーによって受け止められるので、ランプが落下する恐れがなく、従来よりも一層安全性が高まる。   In the lighting fixture of the present invention, not only the lamp base is mounted on the socket, but also the socket cover is mounted on the socket cover receiver, so that the lamp base is mounted on the socket due to vibration during long-term use. Even if the lamp is loosened and removed, the lamp base is received by the socket cover, so that there is no fear of the lamp falling, and the safety is further improved compared to the prior art.

以下、本発明の実施の形態について、図面を参照して詳しく説明する。図1は本発明の実施の形態における照明器具の建造物への取付状態を示す正面図、図2は同照明器具のソケットカバーをソケットカバー受けに装着する状態を示す断面図、図3は同照明器具においてソケットカバーをソケットカバー受けから取り外した状態を示す斜視図、図4は同照明器具の各部を分解して示す断面図である。   Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view showing an attachment state of a lighting fixture to a building in an embodiment of the present invention, FIG. 2 is a cross-sectional view showing a state in which a socket cover of the lighting fixture is attached to a socket cover receiver, and FIG. The perspective view which shows the state which removed the socket cover from the socket cover receptacle in the lighting fixture, FIG. 4: is sectional drawing which decomposes | disassembles and shows each part of the lighting fixture.

この実施の形態の照明器具は、ランプ1と、ランプ取付用のソケット2とを有する。ランプ1は、本例では、直管形の高輝度放電灯(HIDランプ)であって、ソケット2に挿着される口金11と、発光部となるバルブ12と、口金11とバルブ12間を接続する台座13とを備えている。この場合、台座位置13の外径D3は、バルブ12の外径D1よりも大きくなっている。なお、ランプ1は、本例のような高輝度放電灯に限らず、直管型のものであれば、白熱灯や蛍光灯であってもよい。また、ソケット2には、ランプ1との電気的接続を行うためのケーブル3が接続されている。   The lighting fixture of this embodiment includes a lamp 1 and a socket 2 for mounting the lamp. In this example, the lamp 1 is a straight tube type high intensity discharge lamp (HID lamp), and includes a base 11 inserted into the socket 2, a bulb 12 serving as a light emitting portion, and a gap between the base 11 and the bulb 12. And a pedestal 13 to be connected. In this case, the outer diameter D3 of the base position 13 is larger than the outer diameter D1 of the valve 12. The lamp 1 is not limited to the high-intensity discharge lamp as in this example, and may be an incandescent lamp or a fluorescent lamp as long as it is a straight tube type. Further, a cable 3 for electrical connection with the lamp 1 is connected to the socket 2.

また、この照明器具は、ソケット2を覆う有底円筒状のソケットカバー受け4と、このソケットカバー受け4に螺着されるソケットカバー5とを備えている。ソケットカバー受け4は、その上部にネジ穴41が形成されるとともに、ソケット2のケーブル3が挿通されるようになっており、また、外周部には雄ネジ部42が設けられている。そして、ネジ穴41にネジ6を挿通することで、このソケットカバー受け4が支柱、家屋、壁面などの建造物に固定される。   The lighting fixture includes a bottomed cylindrical socket cover receiver 4 that covers the socket 2, and a socket cover 5 that is screwed onto the socket cover receiver 4. The socket cover receiver 4 has a screw hole 41 formed in an upper portion thereof, the cable 3 of the socket 2 is inserted therethrough, and a male screw portion 42 is provided on the outer peripheral portion. Then, by inserting the screw 6 into the screw hole 41, the socket cover receiver 4 is fixed to a building such as a column, a house, or a wall surface.

一方、ソケットカバー5は、略有底円筒状のもので、その内周面には雌ネジ部51が形成され、また、底部中央にはバルブ挿通孔52が形成されている。このバルブ挿通孔52は、その口径D2がランプ1のバルブ12の外径D1よりも大径で、かつ、台座13の外径D3よりも小径になるように予め設定されている。つまり、D1<D2<D3の関係を満たすようになっている。   On the other hand, the socket cover 5 has a substantially bottomed cylindrical shape, and an internal thread portion 51 is formed on the inner peripheral surface, and a valve insertion hole 52 is formed in the center of the bottom portion. The bulb insertion hole 52 is set in advance so that its diameter D2 is larger than the outer diameter D1 of the bulb 12 of the lamp 1 and smaller than the outer diameter D3 of the base 13. That is, the relationship of D1 <D2 <D3 is satisfied.

この照明器具を組み付ける際には、ソケットカバー受け4をネジ6などを適用して支柱、家屋、壁面などの建造物7に固定する。次に、ソケット2を図示ないネジなどを適用してソケットカバー受け4に固定する。また、ソケット2のケーブル3をソケットカバー受け4を通して外部の電気配線に接続する。次に、ランプ1の口金11をソケット2にねじ込んで挿着する。続いて、ソケットカバー5のランプ挿通孔52にランプ1のバルブ12を挿通してから、ソケットカバー5の雌ネジ部51をソケットカバー受け4の雄ネジ部42に螺合してソケットカバー5を固定する。   When this lighting fixture is assembled, the socket cover receiver 4 is fixed to a building 7 such as a column, a house, or a wall surface by applying screws 6 or the like. Next, the socket 2 is fixed to the socket cover receiver 4 by applying a screw or the like (not shown). Further, the cable 3 of the socket 2 is connected to an external electric wiring through the socket cover receiver 4. Next, the base 11 of the lamp 1 is screwed into the socket 2 and inserted. Subsequently, after the bulb 12 of the lamp 1 is inserted into the lamp insertion hole 52 of the socket cover 5, the female screw portion 51 of the socket cover 5 is screwed into the male screw portion 42 of the socket cover receiver 4 to attach the socket cover 5. Fix it.

したがって、この構造の照明器具においては、ランプ1の口金11がソケット2にねじ込み固定されるだけでなく、ソケットカバー5がソケットカバー受け4にねじ込み固定されるので、ランプ1の長期使用中に、振動等に起因してランプ1の口金11がソケット2から緩んで外れても、ランプ1の台座13がソケットカバー5の底部によって受け止められるので、ランプ1が不意に落下することがなく、従来よりもさらに安全性を高めることができる。   Therefore, in the lighting fixture having this structure, not only the base 11 of the lamp 1 is screwed and fixed to the socket 2 but also the socket cover 5 is screwed and fixed to the socket cover receiver 4. Even if the base 11 of the lamp 1 is loosened and removed from the socket 2 due to vibration or the like, the base 13 of the lamp 1 is received by the bottom portion of the socket cover 5, so that the lamp 1 does not drop unexpectedly, and the conventional art. Can further increase safety.
