Description

本発明は、照明器具に関するものである。   The present invention relates to a lighting fixture.

環形ランプ用照明器具は、一般に円盤状のシャーシの中央部に反射板が設けられており、反射板の近傍に環形ランプを装着する。環形ランプの口金の端子部の位置はランプの種類により異なる。例えば、特許文献１には、ランプの口金から内方４５°方向に向けてランプピン（端子部）を設けた環形ランプが開示されている。この環形ランプのランプピンは反射板に直接設けたランプソケットに接続される。また、ランプソケットを反射板に直接設けることなく電気コードで接続するものもある。   In general, an annular lamp illuminator is provided with a reflector at the center of a disk-shaped chassis, and the annular lamp is mounted in the vicinity of the reflector. The position of the terminal portion of the ring lamp base varies depending on the type of lamp. For example, Patent Document 1 discloses an annular lamp in which a lamp pin (terminal portion) is provided in a 45 ° inward direction from a lamp cap. The lamp pin of the annular lamp is connected to a lamp socket provided directly on the reflector. Some lamp sockets are connected by an electric cord without being directly provided on the reflector.

一方、環形ランプには環形ランプ用照明器具に取り付けた際に環形ランプの口金の端子部が反射板側に向くものがある。この場合も、ランプソケットは反射板に直接設置することもできるし、電気コードで接続することもできる。   On the other hand, some ring lamps have a terminal portion of a ring lamp base facing the reflector when attached to a lighting device for a ring lamp. In this case as well, the lamp socket can be installed directly on the reflector, or can be connected with an electric cord.

特開２００２−２５１９１４号公報JP 2002-251914 A

照明器具は輸送時に梱包されるが、梱包時には、環形ランプの口金の端子部をランプソケットに装着し、照明器具の背面（ランプ装着面でない面）を下方にして梱包する。ここで、照明器具が、環形ランプの口金の端子部を反射板側に向けたもので、ランプソケットが電気コードで接続されたものである場合、梱包状態では口金の端子部が下方を向いているため、輸送中の振動等でランプソケットが口金から脱落するおそれがある。   The lighting fixture is packed at the time of transportation. At the time of packing, the terminal portion of the ring lamp base is mounted on the lamp socket, and the lighting fixture is packed with the back surface (the surface not the lamp mounting surface) facing downward. Here, when the lighting fixture is a ring lamp with the terminal portion of the base facing the reflector, and the lamp socket is connected with an electric cord, the terminal portion of the base faces downward in the packaged state. Therefore, the lamp socket may fall off the base due to vibration during transportation.

本発明の目的は、電気コードで接続されたランプソケットがランプの口金から脱落することを防止することができる照明器具を提供することにある。   The objective of this invention is providing the lighting fixture which can prevent that the lamp socket connected with the electric cord falls off from the nozzle | cap | die of a lamp | ramp.

本発明に係る照明器具の一実施例を示す外観斜視図である。It is an external appearance perspective view which shows one Example of the lighting fixture which concerns on this invention. 図１の実施例において環形ランプを取り付けた状態を示す斜視図である。It is a perspective view which shows the state which attached the annular lamp in the Example of FIG. 図１の実施例における環形ランプの口金の周辺部を示す断面図である。It is sectional drawing which shows the peripheral part of the nozzle | cap | die of the annular lamp in the Example of FIG.

図１は、本発明に係る照明器具の一実施例を示す外観斜視図である。本実施例において図示のように、照明器具は、円盤状のシャーシ４０と、シャーシ４０の中央部に配置された反射板２０と、反射板２０に覆われたランプ点灯用の点灯装置（図示せず）と、反射板２０に取り付けられた環形ランプを保持するためのランプ保持部材２２と、点灯装置に電気コード１１で接続され環形ランプの口金の端子部に反射板２０側から装着されるランプソケット１０とを有する。環形ランプの口金と対向する反射板２０の部分には、ソケット１０を収容する凹部２１を備える。反射板２０の中央部には、器具を天井に取り付けるための取付けアダプタを配置するための取り付け孔４１が設けられている。なお、本例の反射板２０は円錐台状をしているが、形状はこれに限定されず、円筒状のものでもよい。   FIG. 1 is an external perspective view showing an embodiment of a lighting fixture according to the present invention. As illustrated in the present embodiment, the lighting fixture includes a disk-shaped chassis 40, a reflector 20 disposed in the center of the chassis 40, and a lighting device for lighting a lamp covered with the reflector 20 (not shown). 1), a lamp holding member 22 for holding the annular lamp attached to the reflecting plate 20, and a lamp connected to the lighting device by the electric cord 11 and attached to the terminal portion of the base of the annular lamp from the reflecting plate 20 side. Socket 10. A portion of the reflecting plate 20 facing the base of the annular lamp is provided with a recess 21 for accommodating the socket 10. An attachment hole 41 for arranging an attachment adapter for attaching the appliance to the ceiling is provided in the central portion of the reflection plate 20. In addition, although the reflecting plate 20 of this example has a truncated cone shape, the shape is not limited thereto, and may be a cylindrical shape.

図２は、図１の実施例においてランプ３０を取り付けた状態を示す斜視図である。本例のランプ３０は二重環形蛍光ランプであるが、本発明はこれに限定されない。ランプ３０は一重環形や四角形状やスクエア形のランプなどでも良く、ランプの形状により本発明の効果が変わることはない。電気コード１１に接続されたソケット１０は、反射板２０の凹部２１の空間を介して、反射板側からランプ３０の口金３１の端子部３２に装着される。この凹部２１は、ランプ３０の口金３１の位置に対応して、例えば図示のように、円錐台状の反射板の斜面をえぐる形で形成される。凹部２１の寸法は、ソケット１０の収容と、ソケット１０に接続される電気コード１１の配線を無理なく行うことができる大きさとされるが、凹部２１が反射板の効果に大きな影響を及ぼさないように、凹部２１のランプ周方向の幅は口金３１のランプ周方向の幅以下であることが好ましい。   FIG. 2 is a perspective view showing a state in which the lamp 30 is attached in the embodiment of FIG. The lamp 30 of this example is a double ring fluorescent lamp, but the present invention is not limited to this. The lamp 30 may be a single ring, square or square lamp, and the effect of the present invention does not change depending on the shape of the lamp. The socket 10 connected to the electric cord 11 is attached to the terminal portion 32 of the base 31 of the lamp 30 from the reflecting plate side through the space of the concave portion 21 of the reflecting plate 20. The concave portion 21 is formed in a shape that surrounds the inclined surface of the truncated cone-shaped reflecting plate, for example, as shown in the figure, corresponding to the position of the base 31 of the lamp 30. The size of the recess 21 is such that the socket 10 can be accommodated and wiring of the electric cord 11 connected to the socket 10 can be performed easily. However, the recess 21 does not greatly affect the effect of the reflector. Furthermore, the width of the recess 21 in the lamp circumferential direction is preferably equal to or less than the width of the base 31 in the lamp circumferential direction.

図３は、図１の実施例における環形ランプの口金３１の周辺部を示す断面図である。ソケット１０は筒状に形成され、一方の端面は口金の端子部３２に装着され、他方の端面は電気コード１１に接続される。ソケット１０直下の電気コード１１と凹部２１の面との距離を、ソケット１０の口金の端子部３２への挿入寸法より小さく設定することで、ソケット１０の脱落を良好に防止することができる。これは照明器具の輸送時において特に有効である。また、ソケット１０に接続される電気コード１１を凹部２１の面につけて配線すると、電気コード１１が支えになるため、ソケット１０の脱落防止に一層効果的である。一方で、ソケット１０に接続される電気コード１１を、ソケット１０に対向する反射板の凹部２１の面との間で間隔をあけて配線することで、ランプ口金部分の通風を確保することができ、ランプ口金温度の低減を図ることができる。   FIG. 3 is a cross-sectional view showing the periphery of the ring lamp base 31 in the embodiment of FIG. The socket 10 is formed in a cylindrical shape, one end surface is attached to the terminal portion 32 of the base, and the other end surface is connected to the electric cord 11. By setting the distance between the electric cord 11 directly below the socket 10 and the surface of the recess 21 to be smaller than the insertion dimension of the base of the socket 10 into the terminal portion 32, the socket 10 can be satisfactorily prevented from falling off. This is particularly effective when transporting the luminaire. Further, when the electric cord 11 connected to the socket 10 is attached to the surface of the recess 21 and wired, the electric cord 11 is supported, which is more effective in preventing the socket 10 from falling off. On the other hand, the electric cord 11 connected to the socket 10 is wired with a space between the surface of the concave portion 21 of the reflecting plate facing the socket 10 so that ventilation of the lamp base portion can be ensured. The lamp base temperature can be reduced.
