図1〜3に本発明のダウンライトの一実施形態を示す。 Figures 1 to 3 show an embodiment of the downlight of the present invention.

ダウンライト1は、ベース10、ランプ本体20、端子台30および2つの取付バネ40、50を備えている。 The downlight 1 includes a base 10, a lamp body 20, a terminal block 30, and two mounting springs 40 and 50.

前記ベース10は、環形の枠体11と、この枠体11の下端外周部に突出するフランジ12とを備えている。 The base 10 includes a ring-shaped frame body 11 and a flange 12 projecting from the outer peripheral portion of the lower end of the frame body 11.

前記ランプ本体20は、ランプが収納された円柱形のランプハウス21と直方体の制御部22とからなり、前記制御部22はランプハウス21の上面の中心Rから側方に寄った位置に設けられている。前記ランプハウス21の中心Rはランプ本体20の中心である。前記ランプハウス21は前記ベース10の枠体11に嵌合されて固定され、下端の導光板23が枠体11から露出している。また、前記制御部22は枠体11の外に突出している。 The lamp body 20 includes a cylindrical lamp house 21 in which a lamp is housed and a rectangular parallelepiped control unit 22, and the control unit 22 is provided at a position closer to the side from the center R on the upper surface of the lamp house 21. ing. The center R of the lamp house 21 is the center of the lamp body 20. The lamp house 21 is fitted and fixed to the frame 11 of the base 10, and the light guide plate 23 at the lower end is exposed from the frame 11. Further, the control unit 22 projects outside the frame body 11.

前記端子台30は前記ランプハウス21の上面に制御部22と並んで配置され、側面に電源線用および送り配線用の2組の端子31、32が取り付けられている。なお、図は各組の端子を1つのみ表示している。前記端子31、32に対し、図2においてAで示す方向から電源線および送り配線等の電線が接続される。 The terminal block 30 is arranged side by side with the control unit 22 on the upper surface of the lamp house 21, and two sets of terminals 31 and 32 for power supply lines and feed wiring are attached to the side surfaces. In the figure, only one terminal of each set is displayed. An electric wire such as a power supply line and a feed wiring is connected to the terminals 31 and 32 from the direction shown by A in FIG.

前記取付バネ40、50は、金属板の複数箇所を屈曲させた弾性変形可能な板バネであり、概ねV字形である。2つの取付バネ40、50はランプハウス21の中心Rに対して対向する位置、即ち2つの取付バネ40、50はランプハウス21の周方向において180°の間隔で配置されている。前記取付バネ40、50は、V字形の一方の要素が基端部41、51となりその先端の屈曲する支持部41a、51aが前記ランプハウス21の上面に固定され、他方の要素が自由端部42、52となってベース10の外方に放射状に張出し、前記基端部41、51と自由端部42、52の間の屈曲部43、53がベース10のフランジ12の上面近くに位置している。前記自由端部42、52は屈曲部43を支点として基端部41、51側に弾性変形し、その復元力によって設置天井に係止される。 The mounting springs 40 and 50 are elastically deformable leaf springs in which a plurality of metal plates are bent, and are generally V-shaped. The two mounting springs 40 and 50 are arranged at positions facing the center R of the lamp house 21, that is, the two mounting springs 40 and 50 are arranged at intervals of 180 ° in the circumferential direction of the lamp house 21. In the mounting springs 40 and 50, one V-shaped element becomes the base end portions 41 and 51, and the bending support portions 41a and 51a at the tip thereof are fixed to the upper surface of the lamp house 21, and the other element is a free end portion. It becomes 42, 52 and extends radially outward of the base 10, and the bent portions 43, 53 between the base end portions 41, 51 and the free end portions 42, 52 are located near the upper surface of the flange 12 of the base 10. ing. The free end portions 42 and 52 are elastically deformed toward the base end portions 41 and 51 with the bent portion 43 as a fulcrum, and are locked to the installation ceiling by the restoring force thereof.

図2において、Pはランプハウス21の中心Rを通り電線の接続方向Aに平行する直線を示している。2つの取付バネ40、50のうちの端子31、32に近い取付バネ40は、前記直線Pに対し、端子31、32から遠ざかる方向に10°の位置に配置されている。前記直線Pは電線等の接続方向Aと平行であるから、取付バネ40は電線等の接続方向Aに対して遠ざかる方向に10°の角度の位置に配置されている。本発明において、取付バネ40の位置は電線等の接続方向Aに対する角度Qで規定され、Qが5°〜20°の範囲とする。このように、電線の接続方向Aに対して角度を持たせると端子31、32前のスペースが広がるので、端子31、32に電線を接続する時に取付バネ40に干渉しにくくなり、接続作業が容易になる。また、電線を接続した後、取付バネ40を弾性変形させる時も電線に干渉しにくい。前記角度Qが5°未満では端子31、32のスペースの拡大も僅かであり上記効果が乏しい。前記角度Qの好ましい範囲は10°〜15°である。 In FIG. 2, P indicates a straight line passing through the center R of the lamp house 21 and parallel to the connection direction A of the electric wires. Of the two mounting springs 40 and 50, the mounting spring 40 close to the terminals 31 and 32 is arranged at a position of 10 ° with respect to the straight line P in the direction away from the terminals 31 and 32. Since the straight line P is parallel to the connection direction A of the electric wire or the like, the mounting spring 40 is arranged at a position at an angle of 10 ° in the direction away from the connection direction A of the electric wire or the like. In the present invention, the position of the mounting spring 40 is defined by the angle Q with respect to the connection direction A of the electric wire or the like, and the Q is in the range of 5 ° to 20 °. In this way, if the wire is angled with respect to the connection direction A, the space in front of the terminals 31 and 32 expands, so that when the wire is connected to the terminals 31 and 32, it is less likely to interfere with the mounting spring 40, and the connection work becomes difficult. It will be easier. Further, even when the mounting spring 40 is elastically deformed after connecting the electric wires, it does not easily interfere with the electric wires. If the angle Q is less than 5 °, the space of the terminals 31 and 32 is slightly expanded, and the above effect is poor. The preferred range of the angle Q is 10 ° to 15 °.

上述したように、前記端子31、32はランプハウス21の中心R(即ちランプ本体20の中心R)から側方に寄った位置に配置されている。しかも、電線の接続方向Aがランプ本体20の中心Rに向かわない位置に端子31、32が取り付けられている。このような位置に端子31、32が取り付けられていると、ランプ本体20に放射状に配置された取付バネ40は電線に近接しやすく両者が干渉しやすいが、取付バネ40を電線の接続方向Aに対して角度を持たせた位置に配置すると端子前31、32のスペースが広がるので両者が干渉しにくくなる。 As described above, the terminals 31 and 32 are arranged at positions closer to the side from the center R of the lamp house 21 (that is, the center R of the lamp body 20). Moreover, the terminals 31 and 32 are attached at positions where the electric wire connection direction A does not face the center R of the lamp body 20. When the terminals 31 and 32 are attached at such positions, the mounting springs 40 radially arranged on the lamp body 20 tend to be close to the electric wire and easily interfere with each other. However, the mounting spring 40 is connected to the electric wire in the connection direction A. If it is arranged at an angle with respect to the terminal, the space in front of the terminals 31 and 32 is widened, so that they are less likely to interfere with each other.

前記取付バネは少なくとも2つ必要であるが、3つ以上の取付バネを有するダウンライトも本発明に含まれる。図4Bに示すように、2つの取付バネを取り付けた場合は、親指と人差指で2つの取付バネを押さえることができるので、片手で設置作業を行うことができる。 Although at least two mounting springs are required, a downlight having three or more mounting springs is also included in the present invention. As shown in FIG. 4B, when the two mounting springs are attached, the two mounting springs can be pressed with the thumb and the index finger, so that the installation work can be performed with one hand.

本発明においてダウンライトの寸法は限定されない。但し、小型のダウンライトでは取付バネや端子の取り付けスペースそのものが小さいために取付バネと端子が近接するので、取付バネと電線の干渉が起こりやすい。従って、本発明は大型のダウンライトよりも小型のダウンライトへの適用意義が大きい。 The size of the downlight is not limited in the present invention. However, in a small downlight, since the mounting space itself for the mounting spring and the terminal is small, the mounting spring and the terminal are close to each other, so that the mounting spring and the electric wire are likely to interfere with each other. Therefore, the present invention has greater significance for application to a small downlight than a large downlight.

また、ダウンライトの取り付けには設置天井の裏側に埋込用の空間が必要であるが、その空間の高さは設置場所によって様々である。空間の高さが十分に深い(高い)場合は端子に接続した電線を取付バネから離れるように押しやることは容易である。しかし、空間の高さが浅い(低い)場合は、電線が設置天井に接触しやすく電線を自由に動かせる範囲が狭くなるために設置作業がしづらくなる。本発明のダウンライトは取付バネが電線から遠ざかる方向に取り付けられて両者の干渉が起こり難いので、埋込用空間の高さの浅い設置天井に対しても設置し易い。 In addition, the installation of the downlight requires a space for embedding behind the installation ceiling, but the height of the space varies depending on the installation location. When the height of the space is sufficiently deep (high), it is easy to push the electric wire connected to the terminal away from the mounting spring. However, when the height of the space is shallow (low), the electric wire easily comes into contact with the installation ceiling and the range in which the electric wire can be freely moved becomes narrow, which makes the installation work difficult. Since the downlight of the present invention is mounted in the direction in which the mounting spring is away from the electric wire and interference between the two is unlikely to occur, it is easy to install the downlight even on an installation ceiling where the height of the embedding space is shallow.

[ダウンライトの設置方法]
図4A〜図4Dを参照しつつ、前記ダウンライト1を天井60の取付穴61に設置する方法を説明する。前記取付穴61の直径は、ダウンライト1のベース10の枠体11よりもやや大きく、フランジ12の外直径よりも小さい。
[How to install the downlight]
A method of installing the downlight 1 in the mounting hole 61 of the ceiling 60 will be described with reference to FIGS. 4A to 4D. The diameter of the mounting hole 61 is slightly larger than the frame 11 of the base 10 of the downlight 1 and smaller than the outer diameter of the flange 12.

まず、図4Aに示すように、天井60の取付穴61から電源線62および送り配線63を引き出して端子31、32に接続する。端子31、32に近い取付バネ40は電源線62および送り配線63から遠ざかる方向に取り付けられているので、取付バネ40に干渉する電源線52および送り配線53を端子31、32に接続できる。 First, as shown in FIG. 4A, the power supply line 62 and the feed wiring 63 are pulled out from the mounting hole 61 of the ceiling 60 and connected to the terminals 31 and 32. Since the mounting spring 40 close to the terminals 31 and 32 is mounted in a direction away from the power supply line 62 and the feed wiring 63, the power supply line 52 and the feed wiring 53 that interfere with the mounting spring 40 can be connected to the terminals 31 and 32.

次に、図4Bおよび図4Cに示すように、手で2つの取付バネ40、50の自由端部42、52を枠体11側に押して弾性変形させて両自由端部42、52間の距離を狭める。前記取付バネ40は電源線52および送り配線53から遠ざかる方向に取り付けられているので、支障なく自由端部42、52を変形させることができる。この状態で取付穴61に端子台30側からベース10の枠体11を挿入する。 Next, as shown in FIGS. 4B and 4C, the free ends 42 and 52 of the two mounting springs 40 and 50 are manually pushed toward the frame 11 side to be elastically deformed and the distance between the two free ends 42 and 52. Narrow. Since the mounting spring 40 is mounted in a direction away from the power supply line 52 and the feed wiring 53, the free end portions 42 and 52 can be deformed without any trouble. In this state, the frame 11 of the base 10 is inserted into the mounting hole 61 from the terminal block 30 side.

そして、図4Dに示すように、取付バネ40、50から手を離すと、弾性変形させた自由端部42、52が復元し、自由端部42、52の根元部42a、52aが取付穴61の周面を押圧する。また、自由端部42、42の先端部42b、52bが天井60の裏面を押圧し、フランジ12と自由端部42、52の先端部42b、52bとで天井60を挟み付ける。これにより、ダウンライト1が2つの取付バネ40、50によって天井60に埋め込まれた状態で固定される。 Then, as shown in FIG. 4D, when the hands are released from the mounting springs 40 and 50, the elastically deformed free end portions 42 and 52 are restored, and the root portions 42a and 52a of the free end portions 42 and 52 are the mounting holes 61. Press the peripheral surface of. Further, the tip portions 42b and 52b of the free end portions 42 and 42 press the back surface of the ceiling 60, and the ceiling 60 is sandwiched between the flange 12 and the tip portions 42b and 52b of the free end portions 42 and 52. As a result, the downlight 1 is fixed in a state of being embedded in the ceiling 60 by two mounting springs 40 and 50.

本発明のダウンライトは天井等に埋め込んで設置される照明器具として利用できる。 The downlight of the present invention can be used as a lighting fixture embedded in a ceiling or the like.
