そして、補助光源７０から出射される光が、パネル５０に照射されないようにする。このとき、パネル５０は、中央部が高くなっているので、光がパネル５０の頂部に当たらず、且つ、照射範囲を広げるように、開口部２２３の内縁部に設けるテーパ２２７の傾斜角度θを設定する。   The panel 50 is prevented from being irradiated with light emitted from the auxiliary light source 70. At this time, since the center of the panel 50 is high, the inclination angle θ of the taper 227 provided at the inner edge of the opening 223 is set so that the light does not strike the top of the panel 50 and the irradiation range is widened. Set.

図５に示すように、アッパーユニット３０は、ＬＥＤ３３を実装する基板３４と、基板３４を器具本体２０の上面に取り付けるための取付部３５と、ＬＥＤ３３の前面を覆うレンズ３６を有する。
取付部３５は全体Ｌ字形状をしており、基板３４およびレンズ３６を、器具本体２０の上面に直交するように取り付ける。従ってＬＥＤ３３からの光は、器具本体２０の上面と平行に外側へ向けて出射される。 As shown in FIG. 5, the upper unit 30 includes a substrate 34 on which the LED 33 is mounted, an attachment portion 35 for attaching the substrate 34 to the upper surface of the instrument body 20, and a lens 36 that covers the front surface of the LED 33.
The attachment portion 35 has an overall L shape, and the substrate 34 and the lens 36 are attached so as to be orthogonal to the upper surface of the instrument body 20. Therefore, the light from the LED 33 is emitted outward in parallel with the upper surface of the instrument body 20.

図６（Ａ）および（Ｂ）に示すように、器具本体２０の上面２０１には、アッパーユニット３０が平面視で略均等に設けられている。
図６（Ａ）に示すように、４個のアッパーユニット３０を設ける場合、中心角９０度で配置する。また、図６（Ｂ）に示すように、８個のアッパーユニット３０を設ける場合、中心角４５度で配置する。
なお、アッパーユニット３０の数は限定するものではなく、任意である。
また、特定の方向を明るく照明したい場合には、アッパーユニット３０のうちの少なくとも一つの光量を、他のアッパーユニット３０の光量よりも大きくすることができる。 As shown in FIGS. 6 (A) and 6 (B), the upper unit 30 is provided on the upper surface 201 of the instrument body 20 substantially equally in plan view.
As shown in FIG. 6A, when four upper units 30 are provided, they are arranged at a central angle of 90 degrees. Further, as shown in FIG. 6B, when eight upper units 30 are provided, they are arranged at a central angle of 45 degrees.
The number of upper units 30 is not limited and is arbitrary.
When it is desired to illuminate a specific direction brightly, at least one light amount of the upper units 30 can be made larger than the light amounts of the other upper units 30.

以上、説明した本発明に係る第１実施形態の照明器具１０によれば、天井面１１に取り付けられる器具本体２０の中央部には、取付金具２１を有し、取付金具２１から供給される電力により制御する制御部２３を有する。また、制御部２３により制御される複数の光源として、器具本体２０の下面中央部に設けられたロアーユニット４０と、器具本体２０の上面に設けられた補助光源７０とを有する。
補助光源７０は、器具本体２０の外周の枠部２２に設けられているので、器具の小型化が可能になり、意匠性が向上する。また、ロアーユニット４０の周囲に補助光源７０を配置したので、器具の直下の照度を上げることができる。 As mentioned above, according to the lighting fixture 10 of 1st Embodiment which concerns on this invention demonstrated in the center part of the fixture main body 20 attached to the ceiling surface 11, it has the attachment metal fitting 21 and the electric power supplied from the attachment metal fitting 21 It has the control part 23 controlled by. The plurality of light sources controlled by the control unit 23 include a lower unit 40 provided at the center of the lower surface of the instrument body 20 and an auxiliary light source 70 provided on the upper surface of the instrument body 20.
Since the auxiliary light source 70 is provided on the frame portion 22 on the outer periphery of the instrument body 20, the instrument can be miniaturized and the design is improved. Moreover, since the auxiliary light source 70 is disposed around the lower unit 40, the illuminance directly below the instrument can be increased.

また、補助光源７０の表面が、枠部２２の表面に沿った形状となっており、補助光源７０が突出しないので、意匠性が向上する。   Moreover, since the surface of the auxiliary light source 70 is shaped along the surface of the frame portion 22 and the auxiliary light source 70 does not protrude, the design is improved.

また、ロアーユニット４０をパネル５０で覆うとともに、補助光源７０から出射される光がロアーユニット４０のパネル５０に照射されないようにした。このため、ロアーユニット４０を消灯して補助光源７０を点灯しても、補助光源７０からの光はパネル５０に照射されないので、補助光源７０の点灯時における外観性を向上できる。また、補助光源７０からの光がパネル５０に遮られないので、光束の損失がない。さらに、部屋に照射された光に、違和感のある影を作るのを防止できる。   Further, the lower unit 40 is covered with the panel 50, and the light emitted from the auxiliary light source 70 is prevented from being irradiated on the panel 50 of the lower unit 40. For this reason, even if the lower unit 40 is turned off and the auxiliary light source 70 is turned on, the light from the auxiliary light source 70 is not applied to the panel 50, so that the appearance when the auxiliary light source 70 is turned on can be improved. Further, since the light from the auxiliary light source 70 is not blocked by the panel 50, there is no loss of light flux. Furthermore, it is possible to prevent a shadow with an uncomfortable feeling from being produced in the light irradiated on the room.

また、補助光源７０が、枠部２２の外形に沿う形状を有するので、大型化を防止するとともに、意匠性の向上を図れる。   In addition, since the auxiliary light source 70 has a shape that follows the outer shape of the frame portion 22, it is possible to prevent an increase in size and to improve design.

また、補助光源７０が、補助光源用レンズ７４を有するので、補助光源用レンズ７４を選択することにより、器具の直下に光を集光させることができる。あるいは、光を拡散させることもできる。
また、ロアーユニット４０とは別の用途の補助光源用レンズ７４を用いることにより、部屋の雰囲気や快適性を変更することができる。 In addition, since the auxiliary light source 70 includes the auxiliary light source lens 74, the light can be condensed immediately below the instrument by selecting the auxiliary light source lens 74. Alternatively, the light can be diffused.
Further, by using the auxiliary light source lens 74 for a different purpose from the lower unit 40, the atmosphere and comfort of the room can be changed.

以上、説明した本発明に係る第１実施形態の照明器具１０によれば、天井面１１に取り付けられる器具本体２０の中央部には、取付金具２１を有し、取付金具２１から供給される電力により制御する制御部２３を有する。また、制御部２３により制御される複数の光源として、器具本体２０の中央部に設けられたロアーユニット４０と、アッパーユニット３０とを有する。
アッパーユニット３０は、器具本体２０と天井面１１との間に設けられて天井面１１を照明するので、アッパーユニット３０は直接見えず、グレアを防止できる。また、アッパーユニット３０が平面視で略均等に配置されているので、器具をどのような向きに取り付けても、部屋全体を照明することができ、部屋の明るさ感が向上する。 As mentioned above, according to the lighting fixture 10 of 1st Embodiment which concerns on this invention demonstrated in the center part of the fixture main body 20 attached to the ceiling surface 11, it has the attachment metal fitting 21 and the electric power supplied from the attachment metal fitting 21 It has the control part 23 controlled by. The plurality of light sources controlled by the control unit 23 include a lower unit 40 and an upper unit 30 provided at the center of the instrument body 20.
Since the upper unit 30 is provided between the instrument body 20 and the ceiling surface 11 and illuminates the ceiling surface 11, the upper unit 30 is not directly visible, and glare can be prevented. In addition, since the upper units 30 are arranged substantially evenly in plan view, the entire room can be illuminated regardless of the orientation of the appliance, and the brightness of the room is improved.

また、アッパーユニット３０のうちの少なくとも一つの光量が，他のアッパーユニット３０の光量よりも大きく設定することにより、特定の方向の光量を上げることができる。これにより、配光効率を向上させることができる。また、部屋の雰囲気を変えることができる。   Further, by setting at least one light amount of the upper units 30 to be larger than the light amounts of the other upper units 30, the light amount in a specific direction can be increased. Thereby, light distribution efficiency can be improved. In addition, the atmosphere of the room can be changed.

（第２実施形態）
次に、本発明に係る第２実施形態の照明器具について、図面を用いて説明する。
なお、前述した第１実施形態に係る照明器具１０と共通する部位には同じ符号を付して、重複する説明を省略することとする。
図７に示すように、第２実施形態の照明器具１０Ｂでは、アッパーユニット３０のうちの少なくとも二つが、平面視で偏っている。
すなわち、アッパーユニット３０は、３個のアッパーユニット３０Ａからなる第１群と、２個のアッパーユニット３０Ｂからなる第２群を有する。ここでは、第２群を、エコナビセンサー２４１側に設定する。 (Second Embodiment)
Next, the lighting fixture of 2nd Embodiment which concerns on this invention is demonstrated using drawing.
In addition, the same code | symbol is attached | subjected to the site | part which is common in the lighting fixture 10 which concerns on 1st Embodiment mentioned above, and the overlapping description is abbreviate | omitted.
As shown in FIG. 7, in the luminaire 10B of the second embodiment, at least two of the upper units 30 are biased in plan view.
That is, the upper unit 30 has a first group composed of three upper units 30A and a second group composed of two upper units 30B. Here, the second group is set on the eco navigation sensor 241 side.

そして、第２群における２個のアッパーユニット３０Ｂの間隔を第１群における３個のアッパーユニット３０Ｂの間隔と異なるように偏らせている。
第１群における３個のアッパーユニット３０Ａの間隔および第１群と第２群との間隔を中心角θ１とし、第２群における２個のアッパーユニット３０Ｂの間隔を中心角θ２とする。従って、第２群における２個のアッパーユニット３０Ｂの間隔を小さくする場合、θ１＞θ２である。
例えば、θ１＝７６．５度とすると、θ２＝５４度となる。
なお、５個のアッパーユニット３０が、同一円内に収容されるように配置すると、間隔を狭めた第２群のアッパーユニット３０Ｂは、中心からの距離が遠くなる。このため、図８に示すように、上カバー３１を図８中上側へ延ばした略長円形状とするのが望ましい。 The distance between the two upper units 30B in the second group is biased to be different from the distance between the three upper units 30B in the first group.
The interval between the three upper units 30A in the first group and the interval between the first group and the second group is defined as a central angle θ1, and the interval between the two upper units 30B in the second group is defined as a central angle θ2. Therefore, when the interval between the two upper units 30B in the second group is reduced, θ1> θ2.
For example, if θ1 = 76.5 degrees, θ2 = 54 degrees.
If the five upper units 30 are arranged so as to be accommodated in the same circle, the distance from the center of the second group of upper units 30 </ b> B having a narrower interval becomes longer. For this reason, as shown in FIG. 8, it is desirable to make the upper cover 31 into a substantially oval shape extending upward in FIG.

図９に示すように、上述した照明器具１０Ｂを、天井面１１の中央に取り付け、第２群をテレビＴＶ側に向けた。
