Description

本発明は、天井又は壁等の造営部に取り付けられる照明装置に関するものである。 The present invention relates to a lighting device attached to a construction part such as a ceiling or a wall.

従来から、天井又は壁等の造営部に取り付けられる照明装置が知られている。この照明装置は、例えば造営部に固定される照明器具と、照明器具に取り付けられる灯具と、を有している。例えば特許文献１に開示された照明装置は、造営部に固定される器具本体と、器具本体に取り付けられる点灯ユニットと、を備えている。この照明装置は、器具本体に設けられた受部に、点灯ユニットに設けられた取付部を取り付けることで、器具本体に点灯ユニットが取り付けられる。受部には、矩形の開口からなる案内部と、長孔から成る保持部と、が形成されている。案内部と保持部とは、連続した孔である。取付部には、受部の案内部に挿入した後、保持部内をスライドさせる突出片が設けられている。取付部は、突出片を案内部に挿入した第１位置から、保持部内をスライドさせて保持される第２位置に配置することで、受部に取り付けることができる。 Conventionally, a lighting device attached to a construction part such as a ceiling or a wall has been known. This luminaire has, for example, a luminaire fixed to a construction unit and a luminaire attached to the luminaire. For example, the lighting device disclosed in Patent Document 1 includes a fixture main body fixed to a building unit and a lighting unit attached to the fixture main body. In this lighting device, the lighting unit is attached to the fixture body by attaching the attachment portion provided to the lighting unit to the receiving portion provided in the fixture main body. The receiving portion is formed with a guide portion having a rectangular opening and a holding portion having an elongated hole. The guide portion and the holding portion are continuous holes. The mounting portion is provided with a protruding piece that slides in the holding portion after being inserted into the guide portion of the receiving portion. The mounting portion can be mounted on the receiving portion by arranging the mounting portion from the first position where the protruding piece is inserted into the guide portion to the second position where the protruding piece is slid and held in the holding portion.

特開２０１８−１４２３２号公報Japanese Unexamined Patent Publication No. 2018-14232

特許文献１に開示された照明装置は、器具本体に設けられた受部の保持部に、点灯ユニットに設けられた取付部の突出片をスライドさせて取り付けることで、器具本体に点灯ユニットを取り付ける構成なので、保持部と突出片との間にスライドを可能する隙間が必要となる。つまり、点灯ユニットと器具本体との間に隙間が生じてしまう。また、この照明装置は、点灯ユニットが器具本体を介して造営部に取り付けられる構成なので、点灯ユニットと造営部とが接触しておらず、点灯ユニットと造営部の間にも隙間が生じる。そのため、この照明装置では、点灯ユニットと器具本体との間の隙間、及び点灯ユニットと造営部との間の隙間によって、点灯ユニットを安定させて取り付けることができないおそれがある。 In the lighting device disclosed in Patent Document 1, the lighting unit is attached to the fixture body by sliding a protruding piece of the attachment portion provided on the lighting unit to the holding portion of the receiving portion provided on the fixture body. Because of the configuration, a gap is required between the holding portion and the protruding piece to allow sliding. That is, a gap is created between the lighting unit and the fixture body. Further, since this lighting device has a configuration in which the lighting unit is attached to the building unit via the fixture main body, the lighting unit and the building unit are not in contact with each other, and a gap is generated between the lighting unit and the building unit. Therefore, in this lighting device, the lighting unit may not be stably mounted due to the gap between the lighting unit and the fixture main body and the gap between the lighting unit and the construction unit.

本発明は、上記のような課題を解決するためになされたもので、天井又は壁等の造営部に安定して灯具を取り付けることができる照明装置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 an object of the present invention is to provide a lighting device capable of stably attaching a lamp to a construction portion such as a ceiling or a wall.

本発明に係る照明装置は、造営部に固定される照明器具と、前記照明器具に装着される灯具と、を備え、前記照明器具は、前記造営部に対して交差させて設けられた器具側取付部を有し、前記灯具には、前記器具側取付部に接続されると共に、前記造営部に接触する灯具側取付部を有するものである。 The luminaire according to the present invention includes a luminaire fixed to the building portion and a luminaire to be attached to the luminaire, and the luminaire is provided so as to intersect the building portion. The lamp has a mounting portion, and the lamp has a lamp-side mounting portion that is connected to the fixture-side mounting portion and is in contact with the construction portion.

本発明によれば、天井面又は壁面等の造営部に、灯具に設けた灯具側取付部を当接させるので、造営部を基準にして灯具の取付姿勢を定めることができる。よって、造営部に対して灯具を理想の取付姿勢に保つことができるので、造営部に安定して灯具を取り付けることができる。 According to the present invention, since the lamp-side mounting portion provided on the lamp is brought into contact with the built-in portion such as the ceiling surface or the wall surface, the mounting posture of the lamp can be determined with reference to the built-in portion. Therefore, since the lamp can be kept in the ideal mounting posture with respect to the building section, the lamp can be stably mounted on the building section.

The contact portion 91 has an overhanging portion 91a that abuts on the construction portion 101, and an inclined surface portion 91b that projects obliquely downward from the overhanging portion 91a toward the end cover 7. As shown in FIGS. 5 and 8, two contact portions 91 are provided at intervals in the lateral direction Y of the lamp 2 with a screw insertion hole 90b in between. As shown in FIG. 11, the distance L3 between the left and right contact portions 91 is equal to or greater than the width dimension L4 of the instrument side mounting portion 12 (L3 ≧ L4). As shown in FIGS. 8 and 12, the fixture side mounting portion 12 of the lighting fixture 1 is arranged between the left and right contact portions 91 in a state where the lamp 2 is mounted on the lighting fixture 1. The inclined surface portion 91b functions as a positioning for restricting the movement of the instrument-side mounting portion 12 arranged between the left and right contact portions 91.

本実施の形態に係る照明装置１００は、図１０及び図１１に示すように、造営部１０１に固定した照明器具１の下方に灯具２を配置し、灯具２を照明器具１に向かって上方へ移動させる。灯具２は、図７〜図９に示すように、灯具側取付部９の当接部９１を造営部１０１に接触させて位置と姿勢が定められた状態で、照明器具１に取り付けられる。つまり、照明装置１００は、灯具２が照明器具１に取り付けられる状態において、天井面又は壁面等の造営部１０１に当接部９１が当接するので、照明器具１の造営部１０１に対する設置状態の如何に関わらず、造営部１０１を基準にして灯具２の取付姿勢を定めることができる。このため、灯具２は、造営部１０１に対して理想の姿勢を保つことができる。また、照明装置１００は、従来技術のように照明器具１に灯具２を左右方向にスライドさせて取り付ける構成ではないので、狭小な施工空間でも照明器具１に灯具２を取り付けることができる。 In the lighting device 100 according to the present embodiment, as shown in FIGS. 10 and 11, the lamp 2 is arranged below the lighting fixture 1 fixed to the construction unit 101, and the lamp 2 is moved upward toward the lighting fixture 1.

As shown in FIGS. 7 to 9, the lamp 2 is attached to the lighting fixture 1 in a state where the contact portion 91 of the lamp side mounting portion 9 is in contact with the construction portion 101 and the position and posture are determined. That is, in the lighting device 100, when the lamp 2 is attached to the lighting fixture 1, the contact portion 91 comes into contact with the building portion 101 such as the ceiling surface or the wall surface, so that the installation state of the lighting fixture 1 with respect to the building portion 101 does not matter. Regardless of this, the mounting posture of the lamp 2 can be determined with reference to the construction unit 101. Therefore, the lamp 2 can maintain an ideal posture with respect to the construction unit 101. Further, since the lighting device 100 is not configured to slide the lamp 2 to the lighting fixture 1 in the left-right direction as in the prior art, the lighting fixture 2 can be attached to the lighting fixture 1 even in a narrow construction space.

また、当接部９１は、ネジ部材から成る固定部材１６を間に挟んで、短手方向Ｙにおける外側に対をなして設けられているので、固定部材１６が器具側取付部１２のネジ挿通孔１２ａにねじ込まれる際に、固定部材１６の軸心を回転中心とする灯具側取付部９の回動を規制することができる。 Further, since the contact portion 91 is provided as a pair on the outer side in the lateral direction Y with the fixing member 16 made of a screw member sandwiched between them, the fixing member 16 is inserted into the screw of the instrument side mounting portion 12. When screwed into the hole 12a, the rotation of the lamp-side mounting portion 9 centered on the axis of the fixing member 16 can be restricted.

また、灯具２の長手方向Ｘにおける両端部に設けられた灯具側取付部９は、図７及び図１０に示すように、器具側取付部１２の外側に位置し、灯具２が照明器具１に取り付けられる際に、器具側取付部１２を案内する機能と、灯具２が照明器具１に取り付けられた状態で、器具側取付部１２の移動を規制する機能と、を有している。 Further, as shown in FIGS. 7 and 10, the lamp side mounting portions 9 provided at both ends of the lamp 2 in the longitudinal direction X are located outside the fixture side mounting portion 12, and the lamp 2 is attached to the lighting fixture 1. It has a function of guiding the fixture side mounting portion 12 when it is attached and a function of restricting the movement of the fixture side mounting portion 12 while the lamp 2 is attached to the lighting fixture 1.

以上のように、本実施の形態に係る照明装置１００は、造営部１０１に固定される照明器具１と、照明器具１に装着される灯具２と、を有している。照明器具１は、造営部１０１に対して交差させて設けられた器具側取付部１２を有している。灯具２には、器具側取付部１２に接続されると共に、造営部１０１に接触する灯具側取付部９を有している。よって、本実施の形態に係る照明装置１００は、灯具２が照明器具１に取り付けられる状態において、天井面又は壁面等の造営部１０１に灯具側取付部９が当接するので、造営部１０１を基準にして灯具２の取付姿勢を定めることができる。よって、照明装置１００は、造営部１０１に対して灯具２を理想の取付姿勢に保つことができるので、造営部１０１に安定して灯具２を取り付けることができる。 As described above, the luminaire 100 according to the present embodiment has a luminaire 1 fixed to the construction unit 101 and a luminaire 2 attached to the luminaire 1. The luminaire 1 has a fixture-side mounting portion 12 provided so as to intersect the construction portion 101. The lamp 2 has a lamp side mounting portion 9 that is connected to the fixture side mounting portion 12 and is in contact with the building portion 101. Therefore, in the lighting device 100 according to the present embodiment, when the lamp 2 is attached to the lighting fixture 1, the lamp side mounting portion 9 comes into contact with the building portion 101 such as the ceiling surface or the wall surface, so that the building portion 101 is used as a reference. The mounting posture of the lamp 2 can be determined. Therefore, since the lighting device 100 can keep the lamp 2 in the ideal mounting posture with respect to the construction unit 101, the lamp 2 can be stably attached to the construction unit 101.
