Description

本発明は、光源ユニット、及び照明器具に関する。 The present invention relates to a light source unit and a luminaire.

図８（ａ）～図８（ｃ）を参照して、特許文献１に記載の照明装置１００について説明する。図８（ａ）は、照明装置１００の模式図である。図８（ｂ）は、図８（ａ）に示す拡散カバー１１０をＷ１方向から見た図である。図８（ｃ）は、図８（ａ）に示す拡散カバー１１０をＷ２方向から見た図である。図８（ａ）に示すように、照明装置１００は、拡散カバー１１０と、反射板１２０と、ＬＥＤ１３０とを備える。拡散カバー１１０の内部には、ＬＥＤ１３０が配置される。反射板１２０の内部には、電源部が配置される。拡散カバー１１０は、反射板１２０に着脱可能である。拡散カバー１１０は、ＬＥＤ１３０が出射した光Ｌを透過させて放出する。 The lighting device 100 described in Patent Document 1 will be described with reference to FIGS. 8 (a) to 8 (c). FIG. 8A is a schematic diagram of the lighting device 100. FIG. 8B is a view of the diffusion cover 110 shown in FIG. 8A as viewed from the W1 direction. FIG. 8 (c) is a view of the diffusion cover 110 shown in FIG. 8 (a) as viewed from the W2 direction. As shown in FIG. 8A, the lighting device 100 includes a diffusion cover 110, a reflector 120, and an LED 130. The LED 130 is arranged inside the diffusion cover 110. A power supply unit is arranged inside the reflector 120. The diffusion cover 110 is removable from the reflector 120. The diffusion cover 110 transmits and emits the light L emitted by the LED 130.

特開２０１５－００２１６１号公報Japanese Patent Application Laid-Open No. 2015-002161

しかし、図８（ａ）、及び図８（ｂ）に示すように、例えば、ＬＥＤ１３０から出射した光Ｌは、ＬＥＤ１３０から略１２０度の角度で広がりながら進行する。従って、拡散カバー１１０の内部にＬＥＤ１３０を配置すると、ＬＥＤ１３０から出射した光Ｌが拡散カバー１１０の側部の上側に到達しにくいおそれがある。理由は、ＬＥＤ１３０と拡散カバー１１０との距離が近く、ＬＥＤ１３０から出射した光が十分に広がらないうちに拡散カバー１１０に到達するからである。この場合、拡散カバー１１０の上部で光Ｌの透過量が低減する。従って、拡散カバー１１０の上部には、暗部Ｚ１が発生する。暗部Ｚ１は、拡散カバー１１０のうち光Ｌが十分に到達する箇所（明部Ｚ２）に比べて、暗い箇所である。従って、暗部Ｚ１が発生することで、拡散カバー１１０の上部に、発光ムラが発生する。発光ムラは、拡散カバー１１０の外面に暗部Ｚ１と明部Ｚ２とのコントラストが発生することである。 However, as shown in FIGS. 8A and 8B, for example, the light L emitted from the LED 130 travels while spreading at an angle of about 120 degrees from the LED 130. Therefore, if the LED 130 is arranged inside the diffusion cover 110, it may be difficult for the light L emitted from the LED 130 to reach the upper side of the side portion of the diffusion cover 110. The reason is that the distance between the LED 130 and the diffusion cover 110 is short, and the light emitted from the LED 130 reaches the diffusion cover 110 before it spreads sufficiently. In this case, the amount of light L transmitted is reduced at the upper part of the diffusion cover 110. Therefore, a dark portion Z1 is generated on the upper portion of the diffusion cover 110. The dark portion Z1 is a dark portion of the diffusion cover 110 as compared with a portion where the light L sufficiently reaches (bright portion Z2). Therefore, the generation of the dark portion Z1 causes uneven light emission in the upper part of the diffusion cover 110. The light emission unevenness is that the contrast between the dark portion Z1 and the bright portion Z2 is generated on the outer surface of the diffusion cover 110.

また、図８（ａ）、及び図８（ｃ）に示すように、ＬＥＤ１３０と拡散カバー１１０の下部との距離Ｖが短いと、拡散カバー１１０の下部に暗部Ｚ３が発生する。具体的には、拡散カバー１１０をＷ２方向（下方）から見て、拡散カバー１１０のうち隣り合うＬＥＤ１３０の間に位置する箇所に、暗部Ｚ３が発生する。暗部Ｚ３は、以下の理由により発生する。一般に、ＬＥＤ１３０が下方に光を出射する際、ＬＥＤ１３０の真下よりもＬＥＤ１３０の真下の周囲が暗くなる。つまり、ＬＥＤ１３０の真下が最も明るくなる。また、ＬＥＤの直下照度はＬＥＤから照射面までの距離に反比例するため、ＬＥＤ１３０の真下の明るさと、ＬＥＤ１３０の真下の周囲の明るさとの差は、光軸方向においてＬＥＤ１３０に近い場所程大きくなる。従って、ＬＥＤ１３０と拡散カバー１１０の下部との距離Ｖが短いと、ＬＥＤ１３０の真下の明るさと、ＬＥＤ１３０の真下の周囲の明るさとの差が大きくなり、拡散カバー１１０の下部に暗部Ｚ３が発生する。その結果、拡散カバー１１０の下部に、発光ムラが発生する。 Further, as shown in FIGS. 8A and 8C, when the distance V between the LED 130 and the lower portion of the diffusion cover 110 is short, a dark portion Z3 is generated in the lower portion of the diffusion cover 110. Specifically, when the diffusion cover 110 is viewed from the W2 direction (below), the dark portion Z3 is generated at a position located between the adjacent LEDs 130 in the diffusion cover 110. The dark portion Z3 is generated for the following reasons. Generally, when the LED 130 emits light downward, the periphery directly below the LED 130 becomes darker than the area directly below the LED 130. That is, the area directly below the LED 130 is the brightest. Further, since the illuminance directly under the LED is inversely proportional to the distance from the LED to the irradiation surface, the difference between the brightness directly under the LED 130 and the brightness of the surroundings directly under the LED 130 becomes larger in the optical axis direction as the location is closer to the LED 130. Therefore, when the distance V between the LED 130 and the lower part of the diffusion cover 110 is short, the difference between the brightness directly under the LED 130 and the brightness of the surroundings directly under the LED 130 becomes large, and a dark portion Z3 is generated in the lower part of the diffusion cover 110. As a result, light emission unevenness occurs in the lower part of the diffusion cover 110.

拡散カバー１１０に発光ムラが発生すると、発光状態における拡散カバー１１０の美観が損なわれるおそれがある。特に、拡散カバー１１０が頻繁に人目に触れる場所（例えば、店舗内の商品売り場、及び住居内のリビングルーム）では、発光ムラが軽減した外観が美しい照明器具を設置したいとの要望がある。発光ムラを軽減するとは、暗部Ｚ１の明るさを明部Ｚ２の明るさに近づけること、及び／又は、拡散カバー（光カバー部）１１０の外面のうち暗部Ｚ１の占める領域を小さくすることを示す。 If uneven light emission occurs in the diffusion cover 110, the appearance of the diffusion cover 110 in the light emitting state may be spoiled. In particular, in a place where the diffusion cover 110 is frequently exposed to the public (for example, a product section in a store and a living room in a house), there is a demand for installing a lighting fixture having a beautiful appearance with reduced light emission unevenness. Reducing light emission unevenness means bringing the brightness of the dark portion Z1 closer to the brightness of the bright portion Z2, and / or reducing the area occupied by the dark portion Z1 on the outer surface of the diffusion cover (light cover portion) 110. ..

本発明は、上記課題に鑑みてなされたものであり、光カバー部に発生する発光ムラを軽減することができる光源ユニット、及び照明器具を提供することを目的としている。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a light source unit and a lighting fixture capable of reducing light emission unevenness generated in a light cover portion.

次に、図３、及び図４を参照して、照明器具１についてさらに説明する。図３は、図１に示すＩＩＩ－ＩＩＩ線に沿った照明器具１の断面図である。図４は、図３の一部拡大図であり、カバー部材３０の断面図である。 Next, the luminaire 1 will be further described with reference to FIGS. 3 and 4. FIG. 3 is a cross-sectional view of the luminaire 1 along the line III-III shown in FIG. FIG. 4 is a partially enlarged view of FIG. 3 and is a cross-sectional view of the cover member 30.

図３、及び図４に示すように、ベース部材１１は、例えば、断面視略Ｕ字形状を有する。ベース部材１１には、第１開口１４が形成される。第１開口１４は、ベース部材１１のうち第３方向Ｒの他側Ｒ２の端部に位置する。第１開口１４は、第１端部１１ｄと、第２端部１１ｅとの間の領域である。第１端部１１ｄは、第１ベース部１１ａのうち第３方向Ｒの他側Ｒ２の端部である。第２端部１１ｅは、第２ベース部１１ｂのうち第３方向Ｒの他側Ｒ２の端部である。第１開口１４は、ベース部材１１の内部Ｃと、ベース部材１１の外部とを連通する。 As shown in FIGS. 3 and 4, the base member 11 has, for example, a substantially U-shaped cross section. The first opening 14 is formed in the base member 11. The first opening 14 is located at the end of the other side R2 of the third direction R in the base member 11. The first opening 14 is a region between the first end 11d and the second end 11e. The first end portion 11d is the end portion of the other side R2 of the third direction R in the first base portion 11a. The second end portion 11e is the end portion of the other side R2 of the third direction R in the second base portion 11b. The first opening 14 communicates the inside C of the base member 11 with the outside of the base member 11.

光カバー部８０は、例えば、断面視略Ｕ字形状を有する。光カバー部８０は、複数の光源２２を覆う。光カバー部８０は、複数の光源２２に対し第３方向Ｒの他側Ｒ２に位置する。従って、光カバー部８０は、第３方向Ｒの他側Ｒ２から複数の光源２２を覆う。 The optical cover portion 80 has, for example, a substantially U-shaped cross-sectional view. The light cover unit 80 covers a plurality of light sources 22. The light cover unit 80 is located on the other side R2 of the third direction R with respect to the plurality of light sources 22. Therefore, the light cover unit 80 covers the plurality of light sources 22 from the other side R2 of the third direction R.

光カバー部８０には、第２開口８１が形成される。第２開口８１は、光カバー部８０の内部Ｄと外部とを連通する。第２開口８１は、光カバー部８０のうち第３方向Ｒの一側Ｒ１の端部に位置する。第２開口８１は、第３端部８０ｄと、第４端部８０ｅとの間の領域である。第３端部８０ｄは、第１カバー部８０ａのうち第３方向Ｒの一側Ｒ１の端部である。第４端部８０ｅは、第２カバー部８０ｂのうち第３方向Ｒの一側Ｒ１の端部である。第２開口８１は、光カバー部８０の内部Ｄと、光カバー部８０の外部とを連通する。 A second opening 81 is formed in the optical cover portion 80. The second opening 81 communicates the inside D of the optical cover portion 80 with the outside. The second opening 81 is located at the end of one side R1 of the third direction R in the optical cover portion 80. The second opening 81 is a region between the third end 80d and the fourth end 80e. The third end portion 80d is an end portion of one side R1 of the third direction R in the first cover portion 80a. The fourth end portion 80e is an end portion of one side R1 of the third direction R in the second cover portion 80b. The second opening 81 communicates the inside D of the optical cover portion 80 with the outside of the optical cover portion 80.

光カバー部８０の第２方向Ｑの寸法α１は、ベース部材１１の第２方向Ｑの寸法α２と略等しい（α１≒α２）。寸法α１は、具体的には、第３端部８０ｄの外側部から第４端部８０ｅの外側部までの寸法を示す。寸法α２は、具体的には、第１端部１１ｄの外側部から第２端部１１ｅの外側部までの寸法を示す。従って、ベース部材１１に光源ユニットＵ２を装着する際、第３端部８０ｄが第１端部１１ｄに接触し、第４端部８０ｅが第２端部１１ｅに接触する。その結果、光カバー部８０がベース部材１１の内部Ｃに進入することが規制される。つまり、光カバー部８０は、ベース部材１１の内部Ｃに進入不能に形成される。 The dimension α1 in the second direction Q of the optical cover portion 80 is substantially equal to the dimension α2 in the second direction Q of the base member 11 (α1≈α2). Specifically, the dimension α1 indicates the dimension from the outer portion of the third end portion 80d to the outer portion of the fourth end portion 80e. Specifically, the dimension α2 indicates the dimension from the outer portion of the first end portion 11d to the outer portion of the second end portion 11e. Therefore, when the light source unit U2 is mounted on the base member 11, the third end portion 80d comes into contact with the first end portion 11d, and the fourth end portion 80e comes into contact with the second end portion 11e. As a result, the optical cover portion 80 is restricted from entering the internal C of the base member 11. That is, the optical cover portion 80 is formed so as not to enter the inside C of the base member 11.

進入部９０は、光カバー部８０に連結される。進入部９０は、光カバー部８０から光カバー部８０の外部に突出する。具体的には、進入部９０は、第２開口８１の縁部に連結される。そして、進入部９０は、第２開口８１の縁部から光カバー部８０の外部に突出する。 The approach portion 90 is connected to the optical cover portion 80. The approach portion 90 projects from the optical cover portion 80 to the outside of the optical cover portion 80. Specifically, the approach portion 90 is connected to the edge portion of the second opening 81. Then, the approach portion 90 projects from the edge portion of the second opening 81 to the outside of the optical cover portion 80.

進入部９０は、本実施形態では、光カバー部８０と一体成形される。従って、進入部９０と、光カバー部８０とが、同じ材料で構成される。
なお、進入部９０を、光カバー部８０と別体で構成し、進入部９０を光カバー部８０に固定してもよい。この場合、進入部９０と光カバー部８０とを異なる材料で構成してもよい。例えば、光カバー部８０については、光が透過する材料で構成するのに対し、進入部９０については、光が透過しない材料で構成する。つまり、光カバー部８０と進入部９０とのうち、少なくとも、光カバー部８０が光を透過すればよい。 In the present embodiment, the approach portion 90 is integrally molded with the optical cover portion 80. Therefore, the approach portion 90 and the optical cover portion 80 are made of the same material.
The approaching portion 90 may be configured separately from the optical cover portion 80, and the approaching portion 90 may be fixed to the optical cover portion 80. In this case, the approach portion 90 and the optical cover portion 80 may be made of different materials. For example, the light cover portion 80 is made of a material that allows light to pass through, while the approach portion 90 is made of a material that does not allow light to pass through. That is, of the light cover portion 80 and the approach portion 90, at least the light cover portion 80 may transmit light.

進入部９０は、ベース部材１１の内部Ｃに進入可能である。従って、進入部９０は、ベース部材１１の内部Ｃに進入する。具体的には、進入部９０は、第１開口１４を介してベース部材１１の内部Ｃに進入する。 The approach portion 90 can enter the inside C of the base member 11. Therefore, the approach portion 90 enters the inside C of the base member 11. Specifically, the approach portion 90 enters the inside C of the base member 11 through the first opening 14.

進入部９０は、第１進入体９１と、第２進入体９２とを有する。第１進入体９１と第２進入体９２とは、互いに間隔を空けて配置される。第１進入体９１と第２進入体９２とは、第２方向Ｑに沿って互いに間隔を空けつつ対向している。 The approach portion 90 has a first approach body 91 and a second approach body 92. The first approaching body 91 and the second approaching body 92 are arranged so as to be spaced apart from each other. The first approaching body 91 and the second approaching body 92 face each other with a distance from each other along the second direction Q.

第１進入体９１と第２進入体９２とは、中心軸βを中心に互いに対称な形状を有している。中心軸βは、光カバー部８０のうち第２方向Ｑの中央部を通りつつ、第３方向Ｒに沿って延びる。 The first approaching body 91 and the second approaching body 92 have shapes symmetrical with each other about the central axis β. The central axis β passes through the central portion of the second direction Q of the optical cover portion 80 and extends along the third direction R.

第１進入体９１は、第１基端部９３ａと、第１先端部９４ａとを有する。第２進入体９２は、第２基端部９３ｂと、第２先端部９４ｂとを有する。
第１進入体９１と第２進入体９２とは、それぞれ、光カバー部８０に連続して設けられる。具体的には、第１進入体９１の第１基端部９３ａは、第１カバー部８０ａの第３端部８０ｄに連続して設けられる。また、第２進入体９２の第２基端部９３ｂは、第２カバー部８０ｂの第４端部８０ｅに連続して設けられる。 The first approaching body 91 has a first base end portion 93a and a first tip portion 94a. The second approaching body 92 has a second base end portion 93b and a second tip portion 94b.
The first approaching body 91 and the second approaching body 92 are continuously provided on the optical cover portion 80, respectively. Specifically, the first base end portion 93a of the first approaching body 91 is continuously provided at the third end portion 80d of the first cover portion 80a. Further, the second base end portion 93b of the second approach body 92 is continuously provided at the fourth end portion 80e of the second cover portion 80b.

第１進入体９１と第２進入体９２とは、光カバー部８０から光カバー部８０の外部へ突出する。
第１進入体９１と第２進入体９２とは、第１カバー部８０ａから離間する程、互いに近接する。第１進入体９１と第２進入体９２とは、それぞれ、複数個所で略直角に曲がる形状を有する。従って、第１進入体９１と第２進入体９２とは、第１カバー部８０ａから離間する程、互いに段階的に近接する。
第１進入体９１の第１先端部９４ａと、第２進入体９２の第２先端部９４ｂとは、それぞれ、第２方向Ｑに沿いつつ中心軸βに向けて突出する。 The first approaching body 91 and the second approaching body 92 project from the optical cover portion 80 to the outside of the optical cover portion 80.
The first approaching body 91 and the second approaching body 92 are so close to each other that they are separated from the first cover portion 80a. The first approaching body 91 and the second approaching body 92 each have a shape that bends at a substantially right angle at a plurality of places. Therefore, the first approaching body 91 and the second approaching body 92 are gradually brought closer to each other so as to be separated from the first cover portion 80a.
The first tip portion 94a of the first approach body 91 and the second tip portion 94b of the second approach body 92 project toward the central axis β along the second direction Q, respectively.

進入部９０の第２方向Ｑの最大寸法α３は、第１開口１４の第２方向Ｑの寸法α４よりも小さい（α３＜α４）。最大寸法α３は、具体的には、第１基端部９３ａの外側部から、第２基端部９３ｂの外側部までの寸法を示す。従って、進入部９０（第１進入体９１と第２進入体９２）は、ベース部材１１の内部Ｃに進入可能に形成される。 The maximum dimension α3 of the approach portion 90 in the second direction Q is smaller than the dimension α4 of the first opening 14 in the second direction Q (α3 <α4). Specifically, the maximum dimension α3 indicates the dimension from the outer portion of the first base end portion 93a to the outer portion of the second base end portion 93b. Therefore, the approach portion 90 (the first approach body 91 and the second approach body 92) is formed so as to be able to enter the inner C of the base member 11.

第１進入体９１と第２進入体９２との間には、空所Ｅが形成される。空所Ｅは、光カバー部８０の外部に配置される。空所Ｅは、光カバー部８０の内部Ｄと連通する。具体的には、空所Ｅは、第２開口８１を介して光カバー部８０の内部Ｄと連通する。空所Ｅには、複数の光源２２が配置される。また、空所Ｅには、実装部材２１が配置される。 A vacant space E is formed between the first approaching body 91 and the second approaching body 92. The vacant space E is arranged outside the optical cover portion 80. The vacant space E communicates with the internal D of the optical cover portion 80. Specifically, the vacant space E communicates with the internal D of the optical cover portion 80 through the second opening 81. A plurality of light sources 22 are arranged in the vacant space E. Further, the mounting member 21 is arranged in the vacant space E.

保持部材５０は、光カバー部８０の外部に配置される。
保持部材５０は、進入部９０に取り付けられる。保持部材５０が進入部９０に取り付けられるとは、例えば、（ａ）保持部材５０が進入部９０に着脱可能に取り付けられること、（ｂ）保持部材５０が進入部９０に固定されること、又は、（ｃ）保持部材５０と進入部９０とが一体成形されることを意味する。本実施形態では、保持部材５０は、進入部９０に着脱可能に取り付けられる。 The holding member 50 is arranged outside the optical cover portion 80.
The holding member 50 is attached to the approach portion 90. When the holding member 50 is attached to the approaching portion 90, for example, (a) the holding member 50 is detachably attached to the approaching portion 90, (b) the holding member 50 is fixed to the approaching portion 90, or , (C) means that the holding member 50 and the approach portion 90 are integrally molded. In the present embodiment, the holding member 50 is detachably attached to the approach portion 90.

保持部材５０は、進入部９０に係合する。保持部材５０は、進入部９０により、スライド可能に支持される。具体的には、保持部材５０は、進入部９０により、第１方向Ｐにスライド可能に支持される。従って、保持部材５０を進入部９０に対し、係合させつつスライドさせることで、保持部材５０を進入部９０に対し、着脱することができる。 The holding member 50 engages with the approach portion 90. The holding member 50 is slidably supported by the approach portion 90. Specifically, the holding member 50 is slidably supported in the first direction P by the approach portion 90. Therefore, by sliding the holding member 50 with respect to the approaching portion 90 while engaging the holding member 50, the holding member 50 can be attached to and detached from the approaching portion 90.

保持部材５０は、第１保持部５１と、第２保持部５２と、取付面５３とを有する。 The holding member 50 has a first holding portion 51, a second holding portion 52, and a mounting surface 53.

第１保持部５１は、進入部９０に対応して設けられ、進入部９０に係合する。第１保持部５１は、第１保持体５１ａと、第２保持体５１ｂとを有する。第１保持体５１ａは、保持部材５０のうち第２方向Ｑの一側Ｑ１に形成される。第２保持体５１ｂは、保持部材５０のうち第２方向Ｑの他側Ｑ２に形成される。 The first holding portion 51 is provided corresponding to the approach portion 90 and engages with the approach portion 90. The first holding portion 51 has a first holding body 51a and a second holding body 51b. The first holding body 51a is formed on one side Q1 of the second direction Q in the holding member 50. The second holding body 51b is formed on the other side Q2 of the second direction Q in the holding member 50.

第１保持体５１ａは、第１進入体９１の第１先端部９４ａに沿った屈曲形状を有する。従って、第１保持体５１ａに第１進入体９１の第１先端部９４ａを嵌め込むことができる。また、第２保持体５１ｂは、第２進入体９２の第２先端部９４ｂに沿った屈曲形状を有する。従って、第２保持体５１ｂに第２進入体９２の第２先端部９４ｂを嵌め込むことができる。 The first holding body 51a has a bent shape along the first tip portion 94a of the first approaching body 91. Therefore, the first tip portion 94a of the first approaching body 91 can be fitted into the first holding body 51a. Further, the second holding body 51b has a bent shape along the second tip portion 94b of the second approaching body 92. Therefore, the second tip portion 94b of the second approaching body 92 can be fitted into the second holding body 51b.

第１保持体５１ａに第１進入体９１の第１先端部９４ａを嵌め込むと共に、第２保持体５１ｂに第２進入体９２の第２先端部９４ｂを嵌め込むことで、保持部材５０が進入部９０に係合する。その結果、保持部材５０が、進入部９０に取り付けられる。
つまり、進入部９０は、互いに間隔を空けて配置される第１進入体９１と第２進入体９２とを有し、第１進入体９１と第２進入体９２とに保持部材５０が取り付けられる。 The holding member 50 enters by fitting the first tip portion 94a of the first approaching body 91 into the first holding body 51a and fitting the second tip portion 94b of the second approaching body 92 into the second holding body 51b. Engage with portion 90. As a result, the holding member 50 is attached to the approach portion 90.
That is, the approach portion 90 has a first approach body 91 and a second approach body 92 arranged at intervals from each other, and a holding member 50 is attached to the first approach body 91 and the second approach body 92. ..

進入部９０は、保持部材５０を、第１方向Ｐに沿ってスライド可能に支持する。従って、保持部材５０を進入部９０に対し、第１方向Ｐに沿ってスライドさせることができる。
保持部材５０が第１方向Ｐに沿ってスライドし、進入部９０から離間すると、保持部材５０と進入部９０との係合が解除される。その結果、保持部材５０が進入部９０から取り外される。 The approach portion 90 slidably supports the holding member 50 along the first direction P. Therefore, the holding member 50 can be slid with respect to the approach portion 90 along the first direction P.
When the holding member 50 slides along the first direction P and separates from the approaching portion 90, the engagement between the holding member 50 and the approaching portion 90 is released. As a result, the holding member 50 is removed from the approach portion 90.

第２保持部５２は、実装部材２１に対応して設けられ、実装部材２１に係合する。第１保持部５１が進入部９０に係合した状態で、保持部材５０のうち光カバー部８０の内部Ｄと対向する面に、第２保持部５２が形成される。第２保持部５２は、第３保持体５２ａと、第４保持体５２ｂとを有する。第３保持体５２ａは、保持部材５０のうち第２方向Ｑの一側Ｑ１に形成される。第４保持体５２ｂは、保持部材５０のうち第２方向Ｑの他側Ｑ２に形成される。 The second holding portion 52 is provided corresponding to the mounting member 21 and engages with the mounting member 21. The second holding portion 52 is formed on the surface of the holding member 50 facing the inner D of the optical cover portion 80 in a state where the first holding portion 51 is engaged with the approaching portion 90. The second holding portion 52 has a third holding body 52a and a fourth holding body 52b. The third holding body 52a is formed on one side Q1 of the second direction Q in the holding member 50. The fourth holding body 52b is formed on the other side Q2 of the second direction Q in the holding member 50.

第３保持体５２ａは、実装部材２１のうち第２方向Ｑの一側Ｑ１の第５端部２１ａに沿った屈曲形状を有する。従って、第３保持体５２ａに実装部材２１の第５端部２１ａを嵌め込むことができる。また、第４保持体５２ｂは、実装部材２１のうち第２方向Ｑの他側Ｑ２の第６端部２１ｂに沿った屈曲形状を有する。従って、第４保持体５２ｂに実装部材２１の第６端部２１ｂを嵌め込むことができる。 The third holding body 52a has a bent shape along the fifth end portion 21a of one side Q1 of the second direction Q among the mounting members 21. Therefore, the fifth end portion 21a of the mounting member 21 can be fitted into the third holding body 52a. Further, the fourth holding body 52b has a bent shape along the sixth end portion 21b of the other side Q2 of the second direction Q in the mounting member 21. Therefore, the sixth end portion 21b of the mounting member 21 can be fitted into the fourth holding body 52b.

第３保持体５２ａに実装部材２１の第５端部２１ａを嵌め込むと共に、第４保持体５２ｂに実装部材２１の第６端部２１ｂを嵌め込むことで、実装部材２１が保持部材５０に係合する。その結果、実装部材２１は、保持部材５０に取り付けられ、保持部材５０により保持される。 The mounting member 21 is engaged with the holding member 50 by fitting the fifth end portion 21a of the mounting member 21 into the third holding body 52a and fitting the sixth end portion 21b of the mounting member 21 into the fourth holding body 52b. It fits. As a result, the mounting member 21 is attached to the holding member 50 and is held by the holding member 50.

保持部材５０は、実装部材２１を第１方向Ｐに沿ってスライド可能に支持する。従って、実装部材２１を保持部材５０に対し、第１方向Ｐに沿ってスライドさせることができる。
実装部材２１が第１方向Ｐに沿ってスライドし、保持部材５０から離間すると、実装部材２１と保持部材５０との係合が解除される。その結果、実装部材２１が保持部材５０から取り外される。 The holding member 50 slidably supports the mounting member 21 along the first direction P. Therefore, the mounting member 21 can be slid with respect to the holding member 50 along the first direction P.
When the mounting member 21 slides along the first direction P and is separated from the holding member 50, the engagement between the mounting member 21 and the holding member 50 is released. As a result, the mounting member 21 is removed from the holding member 50.

以下、複数の光源２２のうちの１つについて説明する。理由は、本実施形態では、複数の光源２２は、互いに同様の構成を有するからである。
光源２２は、発光面２２ａと、光源取付面２２ｂと、側面２２ｃとを有する。光源取付面２２ｂは、光源２２のうち実装部材２１に対向する面である。従って、光源２２の光源取付面２２ｂが、実装部材２１に取り付けられる。
発光面２２ａは、光源取付面２２ｂの裏側に配置される。側面２２ｃは、発光面２２ａと光源取付面２２ｂとの間に配置される。
発光面２２ａは、光源２２のうち光を出射する面である。従って、本実施形態の光源２２は、発光面２２ａと、光源取付面２２ｂと、側面２２ｃとのうち、発光面２２ａから光を出射する。
光源２２は、光カバー部８０の内部Ｄに対向すると共に、光カバー部８０の外部に配置される。具体的には、光源２２の発光面２２ａは、光カバー部８０の内部Ｄに対向すると共に、光カバー部８０の外部に配置される。従って、光源２２は、発光面２２ａから光カバー部８０の内部Ｄに光を出射する。その結果、光カバー部８０の内部Ｄに出射された光は、光カバー部８０を透過し、光カバー部８０の外部へ放出される。
本実施形態では、具体的には、光源２２の発光面２２ａは、第２開口８１を介して光カバー部８０の内部Ｄに対向する。そして、光源２２は、第２開口８１を介して、発光面２２ａから光カバー部８０の内部Ｄに光を出射する。 Hereinafter, one of the plurality of light sources 22 will be described. The reason is that, in the present embodiment, the plurality of light sources 22 have the same configuration as each other.
The light source 22 has a light emitting surface 22a, a light source mounting surface 22b, and a side surface 22c. The light source mounting surface 22b is a surface of the light source 22 facing the mounting member 21. Therefore, the light source mounting surface 22b of the light source 22 is mounted on the mounting member 21.
The light emitting surface 22a is arranged on the back side of the light source mounting surface 22b. The side surface 22c is arranged between the light emitting surface 22a and the light source mounting surface 22b.
The light emitting surface 22a is a surface of the light source 22 that emits light. Therefore, the light source 22 of the present embodiment emits light from the light emitting surface 22a of the light emitting surface 22a, the light source mounting surface 22b, and the side surface 22c.
The light source 22 faces the inside D of the light cover unit 80 and is arranged outside the light cover unit 80. Specifically, the light emitting surface 22a of the light source 22 faces the inside D of the light cover unit 80 and is arranged outside the light cover unit 80. Therefore, the light source 22 emits light from the light emitting surface 22a to the inside D of the light cover unit 80. As a result, the light emitted to the inside D of the optical cover unit 80 passes through the optical cover unit 80 and is emitted to the outside of the optical cover unit 80.
In the present embodiment, specifically, the light emitting surface 22a of the light source 22 faces the inside D of the light cover portion 80 via the second opening 81. Then, the light source 22 emits light from the light emitting surface 22a to the inside D of the light cover portion 80 through the second opening 81.

取付面５３は、保持部材５０のうち、第２保持部５２が形成される面に対する裏側の面である。 The mounting surface 53 is a surface of the holding member 50 on the back side with respect to the surface on which the second holding portion 52 is formed.

取付部材６０は、保持部材５０に取り付けられる。具体的には、取付部材６０は、保持部材５０の取付面５３に取り付けられる。取付部材６０は、弾性を有し、金属製（例えば、ステンレス製）である。 The mounting member 60 is mounted on the holding member 50. Specifically, the mounting member 60 is mounted on the mounting surface 53 of the holding member 50. The mounting member 60 has elasticity and is made of metal (for example, stainless steel).

進入部９０がベース部材１１の内部Ｃに進入した状態で、取付部材６０が、ベース部材１１に固定される。具体的には、進入部９０がベース部材１１の内部Ｃに進入した状態で、取付部材６０の弾性によって、取付部材６０がベース部材１１の内面に圧着する。その結果、ベース部材１１に光源ユニットＵ２が装着される。 The mounting member 60 is fixed to the base member 11 in a state where the approaching portion 90 has entered the inside C of the base member 11. Specifically, in a state where the approaching portion 90 has entered the inner surface C of the base member 11, the mounting member 60 is crimped to the inner surface of the base member 11 by the elasticity of the mounting member 60. As a result, the light source unit U2 is mounted on the base member 11.

ベース部材１１に光源ユニットＵ２が装着されると、光源ユニットＵ２がベース部材１１により保持される。その結果、光源ユニットＵ２が、ベース部材１１を介して取付体に取り付けられ、取付体に設置される。 When the light source unit U2 is attached to the base member 11, the light source unit U2 is held by the base member 11. As a result, the light source unit U2 is attached to the mounting body via the base member 11 and is mounted on the mounting body.

ベース部材１１に光源ユニットＵ２が装着された状態から、光源ユニットＵ２を引っ張り、光源ユニットＵ２をベース部材１１から引き外すことができる。つまり、取付部材６０の弾性力からベース部材１１を解放することで、光源ユニットＵ２をベース部材１１から引き外すことができる。 From the state where the light source unit U2 is attached to the base member 11, the light source unit U2 can be pulled and the light source unit U2 can be pulled out from the base member 11. That is, the light source unit U2 can be pulled out from the base member 11 by releasing the base member 11 from the elastic force of the mounting member 60.

以上、図３及び図４を参照して説明したように、複数の光源２２が、光カバー部８０の内部Ｄに対向すると共に、光カバー部８０の外部に配置される。具体的には、複数の光源２２の各々の発光面２２ａが、光カバー部８０の内部Ｄに対向すると共に、光カバー部８０の外部に配置される。従って、複数の光源２２を光カバー部８０から離間させて配置し、複数の光源２２が出射した光を、光カバー部８０の広範囲の領域に到達させることができる。つまり、複数の光源２２の各々の発光面２２ａから所定角度（例えば、１２０度）で広がりながら進行する光を、光カバー部８０の内部Ｄに進入させて、光カバー部８０の第１カバー部８０ａ及び第２カバー部８０ｂの上端付近まで到達させることができる。その結果、光カバー部８０のほぼ全体を発光させることができ、光カバー部８０に発生する発光ムラを軽減することが可能となる。 As described above with reference to FIGS. 3 and 4, a plurality of light sources 22 face the internal D of the optical cover unit 80 and are arranged outside the optical cover unit 80. Specifically, each light emitting surface 22a of the plurality of light sources 22 faces the inside D of the light cover unit 80 and is arranged outside the light cover unit 80. Therefore, the plurality of light sources 22 can be arranged apart from the light cover unit 80, and the light emitted by the plurality of light sources 22 can reach a wide area of the light cover unit 80. That is, light traveling while spreading at a predetermined angle (for example, 120 degrees) from each light emitting surface 22a of the plurality of light sources 22 is allowed to enter the internal D of the optical cover unit 80 to enter the first cover unit of the optical cover unit 80. It can reach near the upper ends of the 80a and the second cover portion 80b. As a result, almost the entire light cover unit 80 can be made to emit light, and the light emission unevenness generated in the light cover unit 80 can be reduced.

また、保持部材５０は、複数の光源２２を実装する実装部材２１を保持する。そして、保持部材５０は、光カバー部８０の外部に配置される。従って、複数の光源２２が光カバー部８０の外部に配置される。その結果、光カバー部８０に発生する発光ムラを軽減することが可能となる。 Further, the holding member 50 holds a mounting member 21 for mounting a plurality of light sources 22. Then, the holding member 50 is arranged outside the optical cover portion 80. Therefore, a plurality of light sources 22 are arranged outside the optical cover unit 80. As a result, it is possible to reduce the light emission unevenness generated in the light cover unit 80.

また、保持部材５０は、光カバー部８０の外部に配置される。従って、光カバー部８０の内部Ｃが閉塞されている状態で、保持部材５０に対し実装部材２１を着脱する作業を円滑に行うことができる。つまり、光カバー部８０に一対の第２閉塞部材４０が取り付けられた状態で、保持部材５０に対し実装部材２１を着脱する作業を円滑に行うことができる。その結果、光源ユニットＵ２の組立性を向上させることができる。 Further, the holding member 50 is arranged outside the optical cover portion 80. Therefore, the work of attaching / detaching the mounting member 21 to / from the holding member 50 can be smoothly performed while the internal C of the optical cover portion 80 is closed. That is, with the pair of second closing members 40 attached to the optical cover portion 80, the work of attaching and detaching the mounting member 21 to and from the holding member 50 can be smoothly performed. As a result, the assemblability of the light source unit U2 can be improved.

続いて、図３を参照して、ベース部材１１に装着時の光源ユニットＵ２について説明する。 Subsequently, with reference to FIG. 3, the light source unit U2 when mounted on the base member 11 will be described.

図３に示すように、ベース部材１１に光源ユニットＵ２が装着された状態で、光カバー部８０が、ベース部材１１の外部に配置される。 As shown in FIG. 3, the light cover unit 80 is arranged outside the base member 11 with the light source unit U2 mounted on the base member 11.

ベース部材１１に光源ユニットＵ２が装着された状態で、進入部９０（第１進入体９１と第２進入体９２）が、ベース部材１１の内部Ｃに配置される。 With the light source unit U2 mounted on the base member 11, the approaching portion 90 (first approaching body 91 and second approaching body 92) is arranged inside C of the base member 11.

ベース部材１１に光源ユニットＵ２が装着された状態で、保持部材５０が、ベース部材１１の内部Ｃに配置される。 With the light source unit U2 mounted on the base member 11, the holding member 50 is arranged inside C of the base member 11.

ベース部材１１に光源ユニットＵ２が装着された状態で、実装部材２１が、ベース部材１１の内部Ｃに配置される。 The mounting member 21 is arranged inside the base member 11 with the light source unit U2 mounted on the base member 11.

ベース部材１１に光源ユニットＵ２が装着された状態で、空所Ｅが、ベース部材１１の内部Ｃに配置される。ベース部材１１に光源ユニットＵ２が装着された状態で、光カバー部８０の内部Ｄが、ベース部材１１の外部に配置される。 With the light source unit U2 mounted on the base member 11, the space E is arranged inside the base member 11. With the light source unit U2 mounted on the base member 11, the internal D of the optical cover portion 80 is arranged outside the base member 11.

ベース部材１１に光源ユニットＵ２が装着された状態で、複数の光源２２は、光カバー部８０の内部Ｄに対向すると共に、光カバー部８０の外部に配置される。ベース部材１１に光源ユニットＵ２が装着された状態で、複数の光源２２は、ベース部材１１の内部Ｃに配置される。ベース部材１１に光源ユニットＵ２が装着された状態で、複数の光源２２は、それぞれ、中心軸βに交わるように配置される。 With the light source unit U2 mounted on the base member 11, the plurality of light sources 22 face the inside D of the light cover unit 80 and are arranged outside the light cover unit 80. With the light source unit U2 mounted on the base member 11, the plurality of light sources 22 are arranged in the internal C of the base member 11. With the light source unit U2 mounted on the base member 11, the plurality of light sources 22 are arranged so as to intersect the central axis β, respectively.

以上、図３を参照して説明したように、複数の光源２２は、ベース部材１１の内部Ｃに配置される。従って、複数の光源２２を光カバー部８０から離間させて配置し、光カバー部８０に発生する発光ムラを軽減することが可能となる。 As described above with reference to FIG. 3, the plurality of light sources 22 are arranged in the internal C of the base member 11. Therefore, it is possible to arrange the plurality of light sources 22 apart from the light cover unit 80 to reduce the light emission unevenness generated in the light cover unit 80.

また、複数の光源２２をベース部材１１の内部Ｃに配置することで、複数の光源２２と、光カバー部８０の下部（第３カバー部８０ｃ）との距離を増加させることができる。従って、光カバー部８０の下部において、光源２２の真下の明るさと、光源２２の真下の周囲の明るさとの差を小さくすることができる。その結果、光カバー部８０を下方から見て、光カバー部８０のうち隣り合う光源２２の間に位置する箇所に暗部が発生することを抑制することができ、光カバー部８０の下部に発生する発光ムラを軽減することができる。 Further, by arranging the plurality of light sources 22 inside the base member 11, the distance between the plurality of light sources 22 and the lower portion of the optical cover portion 80 (third cover portion 80c) can be increased. Therefore, in the lower part of the light cover portion 80, the difference between the brightness directly under the light source 22 and the brightness of the surroundings directly under the light source 22 can be reduced. As a result, when the light cover portion 80 is viewed from below, it is possible to suppress the generation of a dark portion in a portion of the light cover portion 80 located between the adjacent light sources 22, and it is generated in the lower part of the light cover portion 80. It is possible to reduce uneven light emission.

次に図５～図７を参照して、装着部材７０について説明する。図５は、装着部材７０を示す分解斜視図である。 Next, the mounting member 70 will be described with reference to FIGS. 5 to 7. FIG. 5 is an exploded perspective view showing the mounting member 70.

図５に示すように、装着部材７０は、保持部材５０の第１方向Ｐの端部５０ａに装着される。装着部材７０は、例えば、合成樹脂製である。装着部材７０は、例えば、弾性変形可能である。装着部材７０は、本体部７１と、第１係合部７２と、第２係合部７３と、接触部７４とを有する。本体部７１には、第１係合部７２と、第２係合部７３と、接触部７４とが連結される。本実施形態では、本体部７１と、第１係合部７２と、第２係合部７３と、接触部７４とは、一体成形される。本体部７１は、略平板形状を有する。第１係合部７２と第２係合部７３とは、第２方向Ｑに沿って互いに間隔を空けて対向配置される。第１係合部７２と第２係合部７３とは、それぞれ、第１方向Ｐに沿って本体部７１から突出する。 As shown in FIG. 5, the mounting member 70 is mounted on the end portion 50a of the holding member 50 in the first direction P. The mounting member 70 is made of, for example, a synthetic resin. The mounting member 70 is, for example, elastically deformable. The mounting member 70 has a main body portion 71, a first engaging portion 72, a second engaging portion 73, and a contact portion 74. The first engaging portion 72, the second engaging portion 73, and the contact portion 74 are connected to the main body portion 71. In the present embodiment, the main body portion 71, the first engaging portion 72, the second engaging portion 73, and the contact portion 74 are integrally molded. The main body 71 has a substantially flat plate shape. The first engaging portion 72 and the second engaging portion 73 are arranged so as to face each other at a distance from each other along the second direction Q. The first engaging portion 72 and the second engaging portion 73 each project from the main body portion 71 along the first direction P.

図６は、図３の一部拡大図であり、保持部材５０を示す断面図である。
図５及び図６に示すように、第１係合部７２は、第１保持体５１ａと第３保持体５２ａとで囲まれた空間Ｆ１に対応した形状を有する。第１係合部７２は、空間Ｆ１に嵌入する。また、第２係合部７３は、第２保持体５１ｂと第４保持体５２ｂとで囲まれた空間Ｆ２に対応した形状を有する。第２係合部７３は、空間Ｆ２に嵌入する。第１係合部７２が空間Ｆ１に嵌入すると共に、第２係合部７３が空間Ｆ２に嵌入することで、装着部材７０が保持部材５０に装着される。 FIG. 6 is a partially enlarged view of FIG. 3 and is a cross-sectional view showing a holding member 50.
As shown in FIGS. 5 and 6, the first engaging portion 72 has a shape corresponding to the space F1 surrounded by the first holding body 51a and the third holding body 52a. The first engaging portion 72 fits into the space F1. Further, the second engaging portion 73 has a shape corresponding to the space F2 surrounded by the second holding body 51b and the fourth holding body 52b. The second engaging portion 73 fits into the space F2. The mounting member 70 is mounted on the holding member 50 by fitting the first engaging portion 72 into the space F1 and fitting the second engaging portion 73 into the space F2.

図７は、照明器具１の一部を示す断面図である。具体的には、図７は、図１に示す照明器具１の中央部を第１方向Ｐに平行、かつ、第３方向Ｒに平行に切断した断面図である。
図７は、装着部材７０が保持部材５０に装着された状態を示す。図７に示すように、接触部７４は、第２閉塞部材４０に接触する。従って、装着部材７０は、保持部材５０と第２閉塞部材４０とで第１方向Ｐの両側から挟まれている。その結果、装着部材７０が保持部材５０に装着された状態を保持することができる。 FIG. 7 is a cross-sectional view showing a part of the lighting fixture 1. Specifically, FIG. 7 is a cross-sectional view of the central portion of the luminaire 1 shown in FIG. 1 cut parallel to the first direction P and parallel to the third direction R.
FIG. 7 shows a state in which the mounting member 70 is mounted on the holding member 50. As shown in FIG. 7, the contact portion 74 comes into contact with the second closing member 40. Therefore, the mounting member 70 is sandwiched between the holding member 50 and the second closing member 40 from both sides in the first direction P. As a result, the mounting member 70 can be held in a state of being mounted on the holding member 50.

また、装着部材７０は、実装部材２１に対し第１方向Ｐに対向する。すなわち、装着部材７０は、実装部材２１の第１方向Ｐの端部に対向する。その結果、保持部材５０に対し実装部材２１をスライドさせながら装着する際、実装部材２１を装着部材７０に接触させ、実装部材２１を狙った位置で停止させることができる。つまり、実装部材２１がスライドしすぎて、実装部材２１から抜け落ちることを防ぐことができる。その結果、保持部材５０に実装部材２１を円滑に装着することができ、光源ユニットＵ２の組立性を向上させることができる。 Further, the mounting member 70 faces the mounting member 21 in the first direction P. That is, the mounting member 70 faces the end portion of the mounting member 21 in the first direction P. As a result, when the mounting member 21 is slid and mounted on the holding member 50, the mounting member 21 can be brought into contact with the mounting member 70 and the mounting member 21 can be stopped at a target position. That is, it is possible to prevent the mounting member 21 from sliding too much and falling out of the mounting member 21. As a result, the mounting member 21 can be smoothly mounted on the holding member 50, and the assembling property of the light source unit U2 can be improved.

本実施形態では、装着部材７０は、一対設けられる。一対の装着部材７０のうち１つは、保持部材５０のうち第１方向Ｐの一側Ｐ１の端部に装着される。一対の装着部材７０のうち他の１つは、保持部材５０のうち第１方向Ｐの他側Ｐ２の端部５０ａに装着される。その結果、一対の装着部材７０は、第１方向Ｐの両側から保持部材５０と実装部材２１とを挟持し、保持部材５０と実装部材２１とを保持することができる。 In this embodiment, a pair of mounting members 70 are provided. One of the pair of mounting members 70 is mounted on the end of one side P1 of the first direction P in the holding member 50. The other one of the pair of mounting members 70 is mounted on the end portion 50a of the other side P2 of the first direction P in the holding member 50. As a result, the pair of mounting members 70 can sandwich the holding member 50 and the mounting member 21 from both sides of the first direction P, and can hold the holding member 50 and the mounting member 21.

以上、図面（図１～図７）を参照しながら本発明の実施形態について説明した。但し、本発明は、上記の実施形態に限られるものではなく、その要旨を逸脱しない範囲で種々の態様において実施することが可能である（例えば、下記に示す（１）～（２））。また、上記の実施形態に開示されている複数の構成要素を適宜組み合わせることによって、種々の発明の形成が可能である。例えば、実施形態に示される全構成要素から幾つかの構成要素を削除してもよい。図面は、理解しやすくするために、それぞれの構成要素を主体に模式的に示しており、図示された各構成要素の個数等は、図面作成の都合から実際とは異なる場合もある。また、上記の実施形態で示す各構成要素は一例であって、特に限定されるものではなく、本発明の効果から実質的に逸脱しない範囲で種々の変更が可能である。 The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 7). However, the present invention is not limited to the above embodiment, and can be implemented in various embodiments without departing from the gist of the present invention (for example, (1) to (2) shown below). In addition, various inventions can be formed by appropriately combining the plurality of components disclosed in the above embodiments. For example, some components may be removed from all the components shown in the embodiments. In order to make the drawings easier to understand, each component is schematically shown, and the number of each component shown may differ from the actual one due to the convenience of drawing. Further, each component shown in the above embodiment is an example, and is not particularly limited, and various changes can be made without substantially deviating from the effect of the present invention.

（１）本実施形態では、実装部材２１を保持する保持部材５０が、進入部９０に設けられる。そして、実装部材２１と光カバー部８０とが、取付部材６０を介してベース部材１１に着脱可能に構成される。しかし、本発明はこれに限定されない。実装部材２１を保持する保持部が、ベース部材１１に設けられてもよい。この場合、実装部材２１が、保持部を介してベース部材１１に着脱可能に構成される。そして、光カバー部８０が、取付部材６０を介してベース部材１１に着脱可能に構成される。その結果、実装部材２１（光源２２）を光カバー部８０とは独立させてベース部材１１に着脱することが可能となる。 (1) In the present embodiment, the holding member 50 for holding the mounting member 21 is provided in the approach portion 90. Then, the mounting member 21 and the optical cover portion 80 are detachably configured to be attached to and detached from the base member 11 via the mounting member 60. However, the present invention is not limited to this. A holding portion for holding the mounting member 21 may be provided on the base member 11. In this case, the mounting member 21 is detachably configured to be attached to and detached from the base member 11 via the holding portion. Then, the optical cover portion 80 is detachably configured to be attached to and detached from the base member 11 via the mounting member 60. As a result, the mounting member 21 (light source 22) can be attached to and detached from the base member 11 independently of the optical cover portion 80.

（２）本実施形態では、複数の光源２２が、第１方向Ｐに沿って１列に並ぶ。しかし、本発明はこれに限定されない。複数の光源２２が、第１方向Ｐに沿って複数列で並んでいてもよい。しかし、本実施形態のように複数の光源２２を１列に並べる方が、光源２２の個数を減らすことができ、光源ユニットＵ２の製造コスト、及びランニングコストを削減できる点で有利である。 (2) In the present embodiment, a plurality of light sources 22 are arranged in a row along the first direction P. However, the present invention is not limited to this. A plurality of light sources 22 may be arranged in a plurality of rows along the first direction P. However, arranging a plurality of light sources 22 in a row as in the present embodiment is advantageous in that the number of light sources 22 can be reduced, and the manufacturing cost and running cost of the light source unit U2 can be reduced.

また、複数の光源２２を複数列に並べると、複数の光源２２が、光カバー部８０の側部（第１カバー部８０ａ、及び／又は、第２カバー部８０ｂ）に近接するおそれがある。これに対し、本実施形態のように、複数の光源２２を第１方向Ｐに沿って１列に並べると共に、複数の光源２２を、それぞれ、中心軸β上に配置することで、複数の光源２２が光カバー部８０の側部に近接することを抑制できる。その結果、光カバー部８０の側部に、複数の光源２２の暗部が生じることを効果的に抑制することができる。 Further, when a plurality of light sources 22 are arranged in a plurality of rows, the plurality of light sources 22 may be close to the side portions of the optical cover portion 80 (the first cover portion 80a and / or the second cover portion 80b). On the other hand, as in the present embodiment, a plurality of light sources 22 are arranged in a row along the first direction P, and the plurality of light sources 22 are arranged on the central axis β, respectively, to form a plurality of light sources. It is possible to prevent 22 from approaching the side portion of the optical cover portion 80. As a result, it is possible to effectively suppress the occurrence of dark portions of the plurality of light sources 22 on the side portions of the light cover portion 80.

本発明は、光源ユニット、及び照明器具を提供するものであり、産業上の利用可能性を有する。 The present invention provides a light source unit and a luminaire, and has industrial applicability.
