Description

この発明は、照明器具に関する。   The present invention relates to a lighting fixture.

商品照明等を行うために、照射方向を任意に変更することができるユニバーサルダウンライトが従来から多用されている。ユニバーサルダウンライトに関しては、照射方向の変更範囲を拡げるために、灯体をケースから引き出し得るようにした引き出し型のユニバーサルダウンライトも開発されている(例えば特許文献1)。灯体をケースから引き出することが可能な従来のユニバーサルダウンライトの構造は、特許文献1の図に示されている。
特開平11−339512号公報
Conventionally, universal downlights that can arbitrarily change the irradiation direction have been widely used to perform product illumination and the like. As for the universal downlight, a drawer-type universal downlight has been developed in which the lamp body can be pulled out of the case in order to expand the range of change in the irradiation direction (for example, Patent Document 1). The structure of a conventional universal downlight capable of pulling out the lamp body from the case is shown in the figure of Patent Document 1.
JP-A-11-339512

照射方向を自在に調整できる器具としては、天井直付器具、ダクト取付器具が一般的であるが、天井面をすっきり見せたい場合、引き出し形のユニバーサルダウンライトが好んで用いられる。従来の引き出し型ユニバーサルダウンライトでは、灯体をケースの下方へ完全に引き出すことができるため、照射角度が広範囲に変更される。しかし一方で、下方を照射する場合、灯体をケース内に完全に引き込む必要があるため、昇降ストロークが必要になり、その結果、ダウンライトの全高が大きくなるという課題がある。また、灯体を引き出したときに、ケースの下方に灯体の全体が完全に露出するため、灯体が目立つという意匠上の課題がある。   As a device that can freely adjust the irradiation direction, a direct ceiling mounting device and a duct mounting device are generally used. However, when it is desired to show the ceiling surface clearly, a drawer-type universal downlight is preferably used. In the conventional pull-out type universal downlight, the lamp body can be completely pulled out below the case, so that the irradiation angle is changed in a wide range. However, on the other hand, when illuminating the lower part, since it is necessary to draw the lamp body completely into the case, a lifting stroke is required, and as a result, there is a problem that the overall height of the downlight is increased. In addition, when the lamp body is pulled out, the entire lamp body is completely exposed below the case, so that there is a design problem that the lamp body is conspicuous.

本発明は、照射角度を広範囲に変更できる構成であるとともに、全高を抑制できる薄型の照明器具を提供することを目的とする。   It is an object of the present invention to provide a thin luminaire that is capable of changing the irradiation angle over a wide range and that can suppress the overall height.

It is attached to the main body 10 so as to be rotatable. FIGS. 1A to 1C show a state in which the rotating body 20 is rotating from (a) to (c) with the rotation shaft 83 as an axis. Further, as shown in FIGS. 1B and 2B, the lamp body 30 has a connecting portion 40 that is rotatably connected to the rotating body 20 at its outer edge. As shown in a), the connecting portion 40 can be rotated about the rotating shaft 84 including the layer state in which the lamp body 30 that is the self is the third layer with respect to the rotating body 20 that is the second layer. is there. FIGS. 2A to 2C show a state in which the lamp body 30 is rotated about the rotation shaft 84 from (a) to (c). As shown in FIGS. 1A to 1C and FIGS. 2A to 2C, in the lighting fixture 1000, when the main body 10 is fixed to the ceiling, the rotating body 20 has the rotation shaft 83. The lamp body 30 can be rotated about the center, and the lamp body 30 can be rotated about the rotation shaft 84.

図3〜図5は、照明器具1000の灯体30が回動軸84を中心に回転する様子を説明する図である。図3〜図5において、(a)は上面図であり、(b)は正面図であり、(c)は右側面図であり、(d)は底面図である。図3は、灯体30が回転体20に対して閉じており、本体10、回転体20、灯体30が層状態(例えば図3(b)、(c))をなしている場合を示している。図4は、図4(c)に示すように、灯体30が回転体20に対して45度程度開いた状態を示している。図5は、図5(c)に示すように、灯体30が回転体20に対して90度程度開いた状態を示している。   3-5 is a figure explaining a mode that the lamp 30 of the lighting fixture 1000 rotates centering around the rotating shaft 84. FIG. 3 to 5, (a) is a top view, (b) is a front view, (c) is a right side view, and (d) is a bottom view. FIG. 3 shows a case where the lamp body 30 is closed with respect to the rotating body 20, and the main body 10, the rotating body 20, and the lamp body 30 are in a layered state (for example, FIGS. 3B and 3C). ing. FIG. 4 shows a state where the lamp body 30 is opened about 45 degrees with respect to the rotating body 20 as shown in FIG. FIG. 5 shows a state in which the lamp body 30 is opened about 90 degrees with respect to the rotating body 20 as shown in FIG.

図6は、本体10,回転体20,灯体30の組み付け構造を示す図である。図6は、矢印C方向が室内側であり、矢印D方向が天井側を示す。前述のように、本体10は、ダクト200を介して天井に取り付けられる。回転体20は、図6のように、本体10の中央に設けられた軸穴11に回動自在に支持される。灯体30は、照射角度を広範囲に傾動できるように、回転体20の端部に接続部40により回動自在に接続される。灯体30は、LED31を備えている。この照明器具1000により、高さを低く抑えるとともに、水平方向で略360度、垂直方向で下方垂直から水平まで光を照射することが可能となる。さらに詳しく説明する。
(1)本体10は、外形が円筒形状である。本体10は、円筒形状の上面(天井側の円筒の底面を上面とする)が天井に固定的に取り付けられる。本体10は、円筒の直径に対して円筒の高さが小さい形状である。本体10の下面(天井と反対方向の底面を下面とする)には回転体20が回動自在に取り付けられる。
(2)回転体20は、円形の板状体(円板)である。回転体20の本体10側の面である回転体上面、及び灯体30側の面である回転体下面は、いずれも略円形である。回転体20は、本体10の下面(円形状)の中心を通る直線であってこの下面に垂直な直線が回動軸83となるように、本体10に取り付けられ、回転体上面は本体10の下面と対向するように取り付けられる。本体10と回転体20とは、両者の底面はほぼ同じ大きさである。
(3)灯体30の外形は、回転体20と同様に円板形状である。回転体20と灯体30とは、両者の底面はほぼ同じ大きさである。灯体30は、円板形状の縁の部分に接続部40が形成され、この接続部40により回転体下面の縁の部分において回動自在に回転体20に接続される。図2(b)に示すように、接続部40の形成する回動軸84は、回動軸83に対して略直角方向である。この接続部40により、図2に示したように、灯体30は回転体20に対して、回転体20の回転体下面を覆う方向(回転体20と灯体30との開く角度が狭まる方向)と、その反対方向とに回転することが可能である。
これにより、回転体20は回動軸83を中心として水平方向で略360度回転することがで、また、灯体30は回転体20に対して、回動軸84を中心として、垂直方向で下方垂直から水平(層状態の位置)まで光を照射可能である。
FIG. 6 is a diagram illustrating an assembly structure of the main body 10, the rotating body 20, and the lamp body 30. In FIG. 6, the arrow C direction is the indoor side, and the arrow D direction indicates the ceiling side. As described above, the main body 10 is attached to the ceiling via the duct 200. As shown in FIG. 6, the rotating body 20 is rotatably supported by a shaft hole 11 provided in the center of the main body 10. The lamp body 30 is rotatably connected to the end portion of the rotating body 20 by the connecting portion 40 so that the irradiation angle can be tilted over a wide range. The lamp body 30 includes an LED 31. With this lighting fixture 1000, the height can be kept low, and light can be irradiated from the lower vertical to the horizontal in the vertical direction at about 360 degrees in the horizontal direction. This will be described in more detail.
(1) The main body 10 has a cylindrical outer shape. The main body 10 has a cylindrical upper surface (the bottom surface of the cylinder on the ceiling side is the upper surface) fixedly attached to the ceiling. The main body 10 has a shape in which the height of the cylinder is smaller than the diameter of the cylinder. A rotating body 20 is rotatably attached to the lower surface of the main body 10 (the bottom surface in the direction opposite to the ceiling is the lower surface).
(2) The rotating body 20 is a circular plate-like body (disk). The upper surface of the rotating body that is the surface on the main body 10 side of the rotating body 20 and the lower surface of the rotating body that is the surface on the lamp body 30 side are both substantially circular. The rotating body 20 is attached to the main body 10 so that a straight line passing through the center of the lower surface (circular shape) of the main body 10 and perpendicular to the lower surface becomes the rotation shaft 83, and the upper surface of the rotating body is the upper surface of the main body 10. It is attached so as to face the lower surface. The main body 10 and the rotating body 20 have substantially the same bottom surface.
(3) The outer shape of the lamp body 30 is a disk shape like the rotating body 20. The rotating body 20 and the lamp body 30 have substantially the same bottom surface. The lamp body 30 is formed with a connecting portion 40 at a disc-shaped edge portion, and the connecting portion 40 is connected to the rotating body 20 so as to be rotatable at the edge portion of the lower surface of the rotating body. As shown in FIG. 2B, the rotation shaft 84 formed by the connecting portion 40 is in a substantially right angle direction with respect to the rotation shaft 83. As shown in FIG. 2, the lamp body 30 covers the rotating body 20 with respect to the rotating body 20 by the connecting portion 40 (the direction in which the opening angle between the rotating body 20 and the lamp body 30 is narrowed). ) And the opposite direction.
As a result, the rotating body 20 can rotate approximately 360 degrees in the horizontal direction about the rotation shaft 83, and the lamp body 30 can rotate in the vertical direction about the rotation shaft 84 with respect to the rotation body 20. Light can be irradiated from the lower vertical to the horizontal (layer state position).

図7、図8は、本体10の備える操作部付きプラグ61を説明する図である。図7は照明器具1000のみの図であり、図8は、照明器具1000がダクト200に取り付いた状態を示す図である。図7及び図8では(a)が上面図であり、(b)が左側面図であり、(c)が正面図であり、(d)が右側面図であり、(e)が底面図である。図7(b)に示すように、本体10は、天井面に配設されたダクト200を収納するダクト収納溝71が形成されている。また、本体10は、図7(a)に示すように、ダクトに電気的機械的に接続する操作部付きプラグ61を備えている。操作部付きプラグ61は、操作部62とプラグ63とを有する。図7(a)、(c)、(e)に示すように、操作部62は本体10から突出している。作業者は、図7(d)の矢印64の方向に操作部62を操作することで、プラグ63をダクト200に電気的機械的に接続することができる。図7(d)の場合は、図の位置(操作部62が右側位置)でプラグ63をダクト200に接続できるものとする。   7 and 8 are diagrams illustrating the plug 61 with an operation unit included in the main body 10. FIG. 7 is a view showing only the lighting fixture 1000, and FIG. 8 is a view showing a state where the lighting fixture 1000 is attached to the duct 200. 7 and 8, (a) is a top view, (b) is a left side view, (c) is a front view, (d) is a right side view, and (e) is a bottom view. It is. As shown in FIG. 7B, the main body 10 is formed with a duct housing groove 71 for housing the duct 200 disposed on the ceiling surface. Moreover, the main body 10 is provided with the plug 61 with an operation part which electrically and mechanically connects to a duct, as shown to Fig.7 (a). The plug 61 with an operation unit includes an operation unit 62 and a plug 63. As shown in FIGS. 7A, 7 </ b> C, and 7 </ b> E, the operation unit 62 protrudes from the main body 10. The operator can electrically and mechanically connect the plug 63 to the duct 200 by operating the operation unit 62 in the direction of the arrow 64 in FIG. In the case of FIG. 7D, it is assumed that the plug 63 can be connected to the duct 200 at the position shown in the figure (the operation unit 62 is on the right side).

図9は、複数のLED31を点灯させる第1点灯回路と第2点灯回路の配置を説明する図である。図9(a)は、本体照明器具1000がダクト200に取り付けられた場合の斜視図である。図9(b)は、ダクト200の長手方向に対して、その直角方向を切断した断面を示している。図9(c)は、ダクト200の長手方向に沿って切断した断面を示している。図9(b)、(c)に示すように、本体10は、灯体30の有するLED31を点灯させる第1点灯回路81と第2点灯回路82とを備える。そして、第1点灯回路81と第2点灯回路82とは、図9(b)に示すように、ダクト収納溝71がダクト200を収納した場合に、ダクト200の両側に位置するように配置されている。これにより重量バランスが良好となる。   FIG. 9 is a diagram for explaining the arrangement of the first lighting circuit and the second lighting circuit for lighting the plurality of LEDs 31. FIG. 9A is a perspective view when the main body lighting apparatus 1000 is attached to the duct 200. FIG. 9B shows a cross section obtained by cutting the direction perpendicular to the longitudinal direction of the duct 200. FIG. 9C shows a cross section cut along the longitudinal direction of the duct 200. As shown in FIGS. 9B and 9C, the main body 10 includes a first lighting circuit 81 and a second lighting circuit 82 that turn on the LEDs 31 of the lamp body 30. The first lighting circuit 81 and the second lighting circuit 82 are disposed so as to be positioned on both sides of the duct 200 when the duct storage groove 71 stores the duct 200, as shown in FIG. 9B. ing. Thereby, a weight balance becomes favorable.

実施の形態1の本体照明器具1000は、本体10の中央に設けられた軸穴に回動自在に支持された回転体20と、回転体20の略端部に照射角度を広範囲に傾動できるように設けられた回動軸を備えた灯体30とを備えたので、照射方向を広範囲に変更することができる。また灯体30の出量が小さいので、目立たず、意匠性にも優れる。特に、垂直方向を照射する場合、灯体とケースは略同一円筒に見え、灯体が目立たず、意匠性にも優れる。   The main body lighting fixture 1000 according to the first embodiment can tilt the irradiation angle over a wide range between the rotating body 20 rotatably supported by a shaft hole provided at the center of the main body 10 and the substantially end portion of the rotating body 20. Since the lamp body 30 having the rotation shaft provided in the lamp is provided, the irradiation direction can be changed in a wide range. Moreover, since the amount of the lamp body 30 is small, it is not conspicuous and is excellent in design. In particular, when irradiating in the vertical direction, the lamp body and the case appear to be substantially the same cylinder, the lamp body is not conspicuous, and the design is excellent.

実施の形態1の本体照明器具1000は、本体10が操作部付きプラグ61を備えたので、天井への取り付けの容易性を向上することができる。   In the main body lighting apparatus 1000 according to the first embodiment, the main body 10 includes the plug 61 with the operation unit, so that the ease of attachment to the ceiling can be improved.

実施の形態2.
図10〜図12を参照して実施の形態2を説明する。実施の形態2は、照明器具1000が天井埋め込み型の実施形態である。本体10は、少なくとも一部が天井に埋め込まれることにより天井に取り付けられる。図10を参照して説明する。実施の形態2の照明器具1000は、天井に埋め込まれて取り付けられる。照明器具1000は、取付用バネを備えている。図10(b)に天井の下面の位置を一点鎖線で示した。矢印E方向が室内側である。図10〜図12は、図3〜図5に対応する。すなわち、図10〜図12は、照明器具1000の灯体30が、回動軸84を中心に回転する様子を説明する図である。図10〜図12において、(a)は上面図であり、(b)は正面図であり、(c)は右側面図であり、(d)は底面図である。図10は、灯体30が回転体20に対して閉じており、本体10、回転体20、灯体30が層状態をなしている場合を示している。図11は、図11(c)に示すように、灯体30が回転体20に対して45度程度開いた状態を示している。図12は、図2(c)に示すように、灯体30が回転体20に対して90度程度開いた状態を示している。
Embodiment 2. FIG.
The second embodiment will be described with reference to FIGS. The second embodiment is an embodiment in which the lighting fixture 1000 is embedded in the ceiling. The main body 10 is attached to the ceiling by being at least partially embedded in the ceiling. This will be described with reference to FIG. The lighting fixture 1000 of Embodiment 2 is embedded and attached to the ceiling. The luminaire 1000 includes a mounting spring. FIG. 10B shows the position of the lower surface of the ceiling with a one-dot chain line. The direction of arrow E is the indoor side. 10 to 12 correspond to FIGS. 3 to 5. That is, FIGS. 10-12 is a figure explaining a mode that the lamp 30 of the lighting fixture 1000 rotates centering around the rotating shaft 84. FIG. 10 to 12, (a) is a top view, (b) is a front view, (c) is a right side view, and (d) is a bottom view. FIG. 10 shows a case where the lamp body 30 is closed with respect to the rotating body 20, and the main body 10, the rotating body 20, and the lamp body 30 are in a layered state. FIG. 11 shows a state in which the lamp body 30 is opened about 45 degrees with respect to the rotating body 20 as shown in FIG. FIG. 12 shows a state in which the lamp body 30 is opened about 90 degrees with respect to the rotating body 20 as shown in FIG.

実施の形態2の照明器具1000は、灯体を下方へ引き出すことなく、照射角度を広範囲に変更することができる。これにより、空間形状によって照射できなかった場所や、天井に近いディスプレイポイントへもベストの状態で照明を行うことができる。しかも、灯体30を下方へ引き出す必要がないため、照射方向の調整が容易である。また灯体30の出量が小さいので、目立たず、意匠性にも優れる。特に、垂直方向を照射する場合、出量は極めて小さくでき、灯体30が目立たず、意匠性にも優れる。   The lighting fixture 1000 of Embodiment 2 can change the irradiation angle over a wide range without pulling out the lamp body downward. Thereby, it is possible to illuminate in a best state even on a place that could not be irradiated due to the space shape or on a display point near the ceiling. Moreover, since it is not necessary to pull out the lamp body 30 downward, the irradiation direction can be easily adjusted. Moreover, since the amount of the lamp body 30 is small, it is not conspicuous and is excellent in design. In particular, when irradiating in the vertical direction, the output amount can be made extremely small, the lamp body 30 is not conspicuous, and the design is excellent.
