In addition to the supply unit 4, an appliance body 1, an LED package 2, and a lens body 3 that are attached to the surface of the ceiling plate CB are provided.

器具本体１は、図１に示すように、例えば絶縁性の樹脂成形により、円状の底部１ａと、この外周縁から下方に延設された円筒部１ｂとを一体に有する形状に形成されている。底部１ａには、天井板ＣＢの孔Ｈに通された電源接続線Ｗ１を介してＬＥＤ電源供給部４の出力に電気的に接続される接続部（コネクタ）１ｃが下面中央に設けられているとともに、当該器具本体１を天井板ＣＢの表面にねじ止め固定するための一対の取付孔１ｄが接続部１ｃの両側に穿設されている。さらに、円筒部１ｂには、ねじ溝１ｅが外周壁に形成されている。   As shown in FIG. 1, the instrument main body 1 is formed into a shape integrally including a circular bottom 1 a and a cylindrical portion 1 b extending downward from the outer peripheral edge by, for example, insulating resin molding. Yes. A connection portion (connector) 1c that is electrically connected to the output of the LED power supply portion 4 via the power supply connection line W1 that is passed through the hole H of the ceiling plate CB is provided at the bottom surface 1a. In addition, a pair of mounting holes 1d for screwing and fixing the appliance body 1 to the surface of the ceiling plate CB is formed on both sides of the connecting portion 1c. Further, a thread groove 1e is formed in the outer peripheral wall of the cylindrical portion 1b.

ＬＥＤパッケージ２は、電子部品が実装され器具本体１内に着脱自在に収納される円状の実装基板（プリント基板）２ａに形成されており、器具本体１の接続部１ｃにコネクタ接続される接続部２ｃを実装基板２ａの上面中央に備え、実装基板２ａの下面には、実装基板２ａの中心に対して円環状に配置された複数のＬＥＤ素子２ｂが周縁に沿って実装されている。これらのＬＥＤ素子２ｂには、ＬＥＤ電源供給部４から接続部１ｃ，２ｃを介して点灯電力が供給される。   The LED package 2 is formed on a circular mounting board (printed circuit board) 2a on which electronic components are mounted and detachably housed in the instrument body 1, and is connected to the connection portion 1c of the instrument body 1 by a connector. A portion 2c is provided at the center of the upper surface of the mounting substrate 2a, and a plurality of LED elements 2b arranged in an annular shape with respect to the center of the mounting substrate 2a are mounted on the lower surface of the mounting substrate 2a along the periphery. Lighting power is supplied to the LED elements 2b from the LED power supply unit 4 through the connection units 1c and 2c.

レンズ体３は、例えば絶縁性の樹脂成形により、円状の底部３ａと、この外周縁から上方に延設された円筒部３ｂとを一体に有する形状に形成されている。底部３ａには、レンズ３ｃが周縁に沿って円環状に形成されており、レンズ３ｃはＬＥＤ素子２ｂが発する光を制御（配光，集光）する。また、円筒部３ｂには、器具本体１のねじ溝１ｅと嵌合するねじ溝３ｄが内周壁に形成されている。   The lens body 3 is formed in a shape integrally including a circular bottom portion 3a and a cylindrical portion 3b extending upward from the outer peripheral edge by, for example, insulating resin molding. A lens 3c is formed in an annular shape along the periphery on the bottom 3a, and the lens 3c controls (light distribution, condensing) light emitted from the LED element 2b. In addition, the cylindrical portion 3b is formed with a screw groove 3d that fits into the screw groove 1e of the instrument body 1 on the inner peripheral wall.

次に、ＬＥＤ照明器具の天井板ＣＢへの取付手順について説明すると、まず、器具本体１を各取付孔１ｄを介してねじ止めすることで天井板ＣＢの表面に固定する。そして、ＬＥＤパッケージ２の接続部２ｃを器具本体１の接続部１ｃにコネクタ接続して、ＬＥＤパッケージ２を器具本体１に収納する。このとき、複数のＬＥＤ素子２ｂは器具本体１の中心に対して円環状に配置されている。この後、器具本体１のねじ溝１ｅにレンズ体３のねじ溝３ｄをねじ合わせて、レンズ体３を器具本体１に螺着する。このとき、レンズ３ｃも器具本体１の中心に対して円環状となるように形成されており、レンズ３ｃは複数のＬＥＤ素子２ｂからなる円環と同軸に配置され、各ＬＥＤ素子２ｂは円環状のレンズ３ｃに対向する。   Next, a procedure for attaching the LED lighting fixture to the ceiling plate CB will be described. First, the fixture body 1 is fixed to the surface of the ceiling plate CB by screwing it through the attachment holes 1d. Then, the connection portion 2 c of the LED package 2 is connected to the connection portion 1 c of the instrument body 1 by a connector, and the LED package 2 is accommodated in the instrument body 1. At this time, the plurality of LED elements 2 b are arranged in an annular shape with respect to the center of the instrument body 1. Thereafter, the thread groove 3 d of the lens body 3 is screwed with the thread groove 1 e of the instrument body 1, and the lens body 3 is screwed to the instrument body 1. At this time, the lens 3c is also formed in an annular shape with respect to the center of the instrument body 1, and the lens 3c is arranged coaxially with an annular shape composed of a plurality of LED elements 2b, and each LED element 2b is annular. It faces the lens 3c.

このように、複数のＬＥＤ素子２ｂは円環状に配置され、レンズ３ｃは複数のＬＥＤ素子２ｂからなる円環と同軸の円環状に形成されているので、ＬＥＤパッケージ２を収納した器具本体１の下方からレンズ体３を同軸に回転させて螺着させることで、各ＬＥＤ素子２ｂは円環状のレンズ３ｃに対向する位置に常にあり、レンズ体３を回転させて器具本体１に螺着する際の回転方向の位置決めが容易になる。   In this way, the plurality of LED elements 2b are arranged in an annular shape, and the lens 3c is formed in an annular shape that is coaxial with the ring made up of the plurality of LED elements 2b. By rotating the lens body 3 coaxially and screwing from below, each LED element 2b is always in a position facing the annular lens 3c, and when the lens body 3 is rotated and screwed to the instrument body 1 Positioning in the rotation direction becomes easy.

なお、本実施形態では、複数のＬＥＤ素子２ｂを１重の円環状に配置し、レンズ３ｃも１重に形成しているが、複数のＬＥＤ素子２ｂを２重以上の円環状に配置し、レンズ３ｃも２重以上の円環状に形成しても、上記同様の効果を得ることができる。   In the present embodiment, the plurality of LED elements 2b are arranged in a single annular shape, and the lens 3c is also formed in a single shape. However, the plurality of LED elements 2b are arranged in a double or more annular shape, Even if the lens 3c is formed in a double or more annular shape, the same effect as described above can be obtained.
