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 lighting equipment.

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 illumination 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 illumination device 100. FIG. FIG. 8(b) is a view of the diffusion cover 110 shown in FIG. 8(a) viewed from the W1 direction. FIG. 8(c) is a view of the diffusion cover 110 shown in FIG. 8(a) as seen from the W2 direction. As shown in FIG. 8( a ), lighting device 100 includes diffusion cover 110 , reflector 120 , and LED 130 . An LED 130 is arranged inside the diffusion cover 110 . A power supply unit is arranged inside the reflector 120 . The diffusion cover 110 is detachable 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JP 2015-002161 A

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 diverging from the LED 130 at an angle of approximately 120 degrees. Therefore, if the LEDs 130 are arranged inside the diffusion cover 110 , the light L emitted from the LEDs 130 may be difficult to reach the upper sides of the diffusion cover 110 . The reason is that the distance between the LEDs 130 and the diffusion cover 110 is short, and the light emitted from the LEDs 130 reaches the diffusion cover 110 before it spreads sufficiently. In this case, the amount of light L transmitted through the upper portion of the diffusion cover 110 is reduced. Accordingly, a dark portion Z1 is generated in the upper portion of the diffusion cover 110. FIG. The dark portion Z1 is a portion darker than the portion of the diffusion cover 110 where the light L sufficiently reaches (bright portion Z2). Therefore, due to the occurrence of the dark portion Z1, uneven light emission occurs in the upper portion of the diffusion cover 110. FIG. The uneven light emission is the occurrence of contrast between the dark portion Z1 and the bright portion Z2 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。 Moreover, 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. FIG. Specifically, when the diffusion cover 110 is viewed from the W2 direction (downward), a dark portion Z3 is generated in a portion of the diffusion cover 110 located between the adjacent LEDs 130 . The dark area Z3 is generated for the following reasons. In general, when the LED 130 emits light downward, the area directly below the LED 130 is darker than the area directly below the LED 130 . That is, directly below the LED 130 is the brightest. In addition, since the illuminance directly below the LED is inversely proportional to the distance from the LED to the irradiation surface, the difference between the brightness directly below the LED 130 and the brightness of the surroundings directly below the LED 130 becomes greater at locations closer to the LED 130 in the optical axis direction. Therefore, when the distance V between the LEDs 130 and the lower portion of the diffusion cover 110 is short, the difference between the brightness directly below the LEDs 130 and the brightness of the surroundings immediately below the LEDs 130 increases, and a dark portion Z3 is generated in the lower portion of the diffusion cover 110. As a result, uneven light emission occurs in the lower portion 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 the light emission unevenness occurs in the diffusion cover 110, the appearance of the diffusion cover 110 in the light-emitting state may be spoiled. Especially in places where the diffusion cover 110 is frequently seen (for example, a product sales floor in a store and a living room in a house), there is a demand to install a lighting fixture with a beautiful appearance with reduced light emission unevenness. Reducing unevenness in light emission 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 thereof is to provide a light source unit and a lighting fixture that can reduce uneven light emission that occurs 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 lighting device 1 will be further described with reference to FIGS. 3 and 4. FIG. FIG. 3 is a cross-sectional view of the luminaire 1 taken along line III-III shown in FIG. 4 is a partially enlarged view of FIG. 3 and a cross-sectional view of the cover member 30. FIG.

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. A first opening 14 is formed in the base member 11 . The first opening 14 is positioned at the end of the base member 11 on the other side R2 in the third direction R. As shown in FIG. The first opening 14 is a region between the first end portion 11d and the second end portion 11e. The first end portion 11d is the end portion on the other side R2 in the third direction R of the first base portion 11a. The second end portion 11e is the end portion on the other side R2 in the third direction R of 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 light cover part 80 has, for example, a substantially U-shaped cross section. The light cover portion 80 covers the multiple light sources 22 . The light cover part 80 is positioned on the other side R<b>2 in the third direction R with respect to the plurality of light sources 22 . Therefore, the light cover part 80 covers the plurality of light sources 22 from the other side R2 in the third direction R. As shown in FIG.

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 light cover portion 80 . The second opening 81 communicates the inside D and the outside of the light cover portion 80 . The second opening 81 is located at the end of the one side R1 in the third direction R of 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 on one side R1 in the third direction R of the first cover portion 80a. The fourth end portion 80e is the end portion of the second cover portion 80b on one side R1 in the third direction R. As shown in FIG. The second opening 81 communicates the inside D of the light cover portion 80 with the outside of the light 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 of the light cover portion 80 in the second direction Q is substantially equal to the dimension α2 of the base member 11 in the second direction Q (α1≈α2). The dimension α1 specifically indicates the dimension from the outer portion of the third end portion 80d to the outer portion of the fourth end portion 80e. The dimension α2 specifically 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 attached to the base member 11, the third end 80d contacts the first end 11d, and the fourth end 80e contacts the second end 11e. As a result, entry of the light cover portion 80 into the interior C of the base member 11 is restricted. That is, the light cover portion 80 is formed so as not to be able 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 entrance portion 90 is connected to the light cover portion 80 . The entrance portion 90 protrudes from the optical cover portion 80 to the outside of the optical cover portion 80 . Specifically, the entry portion 90 is connected to the edge of the second opening 81 . The entrance portion 90 protrudes from the edge portion of the second opening 81 to the outside of the light 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。 The entrance portion 90 is integrally formed with the light cover portion 80 in this embodiment. Therefore, the entrance portion 90 and the light cover portion 80 are made of the same material.
Note that the entrance portion 90 may be configured separately from the light cover portion 80 and the entrance portion 90 may be fixed to the light cover portion 80 . In this case, the entrance portion 90 and the light cover portion 80 may be made of different materials. For example, the light cover portion 80 is made of a light-transmissive material, whereas the entrance portion 90 is made of a light-impermeable material. That is, at least the light cover portion 80 of the light cover portion 80 and the entrance portion 90 should 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 entry portion 90 can enter the inside C of the base member 11 . Accordingly, the entry portion 90 enters the interior C of the base member 11 . Specifically, the entry portion 90 enters the interior 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 entrance section 90 has a first entrance body 91 and a second entrance body 92 . The first entrance body 91 and the second entrance body 92 are spaced apart from each other. The first entrance body 91 and the second entrance body 92 are opposed to each other along the second direction Q with a gap therebetween.

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 inserting body 91 and the second inserting body 92 have shapes symmetrical to each other about the central axis β. The central axis β extends along the third direction R while passing through the central portion of the light cover portion 80 in the second direction Q. As shown in FIG.

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 inserter 91 has a first proximal end 93a and a first distal end 94a. The second inserter 92 has a second proximal end 93b and a second distal end 94b.
The first entrance body 91 and the second entrance body 92 are provided continuously with the light cover portion 80 respectively. Specifically, the first base end portion 93a of the first inserting body 91 is provided continuously with the third end portion 80d of the first cover portion 80a. Also, the second base end portion 93b of the second inserting body 92 is provided continuously with 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 entrance body 91 and the second entrance body 92 protrude from the optical cover section 80 to the outside of the optical cover section 80 .
The first inserting body 91 and the second inserting body 92 are closer to each other as they are separated from the first cover portion 80a. Each of the first inserting body 91 and the second inserting body 92 has a shape that bends substantially at right angles at a plurality of points. Therefore, the first inserting body 91 and the second inserting body 92 approach each other step by step as the distance from the first cover portion 80a increases.
A first tip portion 94a of the first inserting body 91 and a second tip portion 94b of the second inserting body 92 protrude 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 entrance 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). The maximum dimension α3 specifically 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 entrance portion 90 (the first entrance body 91 and the second entrance body 92 ) is formed to be able to enter the interior 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 space E is formed between the first entrance body 91 and the second entrance body 92 . The void E is arranged outside the light cover portion 80 . The space E communicates with the interior D of the light cover portion 80 . Specifically, the space E communicates with the inside D of the light cover portion 80 via the second opening 81 . A plurality of light sources 22 are arranged in the space E. As shown in FIG. Also, in the space E, a mounting member 21 is arranged.

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 light cover portion 80 .
The holding member 50 is attached to the entry portion 90 . The holding member 50 attached to the entrance section 90 means, for example, (a) that the holding member 50 is detachably attached to the entrance section 90, (b) that the holding member 50 is fixed to the entrance section 90, or , (c) means that the holding member 50 and the entrance portion 90 are integrally molded. In this embodiment, the holding member 50 is detachably attached to the entrance 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。 Retaining member 50 engages entry 90 . The holding member 50 is slidably supported by the entry portion 90 . Specifically, the holding member 50 is slidably supported in the first direction P by the entrance portion 90 . Therefore, the holding member 50 can be attached to and detached from the entering portion 90 by sliding the holding member 50 with respect to the entering portion 90 while engaging it.

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 entering portion 90 and engages with the entering 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 holding member 50 in the second direction Q. As shown in FIG. The second holding body 51b is formed on the other side Q2 of the holding member 50 in the second direction Q. As shown in FIG.

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 51 a has a curved shape along the first tip portion 94 a of the first inserting body 91 . Therefore, the first tip portion 94a of the first inserting body 91 can be fitted into the first holding body 51a. Also, the second holding body 51b has a curved shape along the second tip portion 94b of the second inserting body 92 . Therefore, the second tip portion 94b of the second inserting 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。 By fitting the first end portion 94a of the first insertion body 91 into the first holding body 51a and fitting the second end portion 94b of the second insertion body 92 into the second holding body 51b, the holding member 50 is inserted. engage portion 90; As a result, the holding member 50 is attached to the entry portion 90 .
That is, the entry part 90 has a first entry body 91 and a second entry body 92 which are spaced apart from each other, and the holding member 50 is attached to the first entry body 91 and the second entry 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 entrance portion 90 supports the holding member 50 so as to be slidable along the first direction P. As shown in FIG. Therefore, the holding member 50 can be slid along the first direction P with respect to the entrance portion 90 .
When the holding member 50 slides along the first direction P and separates from the entrance portion 90, the engagement between the holding member 50 and the entrance portion 90 is released. As a result, the holding member 50 is removed from the entry 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 . A second holding portion 52 is formed on a surface of the holding member 50 facing the inside D of the light cover portion 80 while the first holding portion 51 is engaged with the entrance portion 90 . The second holding part 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 holding member 50 in the second direction Q. As shown in FIG. The fourth holding body 52b is formed on the other side Q2 of the holding member 50 in the second direction Q. As shown in FIG.

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 21a on the one side Q1 in the second direction Q of the mounting member 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 on the other side Q2 of the mounting member 21 in the second direction Q. As shown in FIG. 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 21a of the mounting member 21 into the third holding body 52a and fitting the sixth end 21b of the mounting member 21 into the fourth holding body 52b. match. As a result, the mounting member 21 is attached to the holding member 50 and 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. As shown in FIG. Therefore, the mounting member 21 can be slid along the first direction P with respect to the holding member 50 .
When the mounting member 21 slides along the first direction P and separates 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。 One of the plurality of light sources 22 will be described below. The reason is that in this embodiment, the plurality of light sources 22 have similar configurations.
The light source 22 has a light emitting surface 22a, a light source mounting surface 22b, and side surfaces 22c. The light source mounting surface 22 b is a surface of the light source 22 facing the mounting member 21 . Accordingly, the light source attachment surface 22b of the light source 22 is attached to the mounting member 21. As shown in FIG.
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 from which light is emitted. Therefore, the light source 22 of this embodiment emits light from the light emitting surface 22a out 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 portion 80 and is arranged outside the light cover portion 80 . Specifically, the light emitting surface 22 a of the light source 22 faces the inside D of the light cover portion 80 and is arranged outside the light cover portion 80 . Therefore, the light source 22 emits light from the light emitting surface 22 a to the inside D of the light cover portion 80 . As a result, the light emitted to the inside D of the light cover portion 80 passes through the light cover portion 80 and is emitted to the outside of the light cover portion 80 .
Specifically, in this embodiment, the light emitting surface 22 a of the light source 22 faces the inside D of the light cover portion 80 through the second opening 81 . Then, the light source 22 emits light from the light emitting surface 22 a to the inside D of the light cover portion 80 via 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 the surface of the holding member 50 on the back side of 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 attachment member 60 is attached to the holding member 50 . Specifically, the attachment member 60 is attached to the attachment 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 attachment member 60 is fixed to the base member 11 in a state in which the entrance portion 90 has entered the interior C of the base member 11 . Specifically, the mounting member 60 is crimped to the inner surface of the base member 11 due to the elasticity of the mounting member 60 in a state in which the entering portion 90 has entered the interior C of the base member 11 . As a result, the light source unit U<b>2 is attached to 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 U<b>2 is attached to the base member 11 , the light source unit U<b>2 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 installed 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。 The light source unit U2 can be removed from the base member 11 by pulling the light source unit U2 from the state where the light source unit U2 is attached to the base member 11 . In other words, by releasing the base member 11 from the elastic force of the mounting member 60, the light source unit U2 can be removed from the base member 11. FIG.

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 , the plurality of light sources 22 are arranged outside the light cover portion 80 while facing the inside D of the light cover portion 80 . Specifically, the light emitting surface 22 a of each of the plurality of light sources 22 faces the inside D of the light cover portion 80 and is arranged outside the light cover portion 80 . Therefore, the plurality of light sources 22 can be spaced apart from the light cover portion 80 and the light emitted from the plurality of light sources 22 can reach a wide area of the light cover portion 80 . In other words, the light traveling while spreading at a predetermined angle (for example, 120 degrees) from the light emitting surface 22a of each of the plurality of light sources 22 is caused to enter the interior D of the light cover portion 80, thereby causing the first cover portion of the light cover portion 80 to enter. It can reach near the upper ends of 80a and the second cover portion 80b. As a result, almost the entire light cover portion 80 can be caused to emit light, and uneven light emission occurring in the light cover portion 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。 Also, the holding member 50 holds the mounting member 21 on which the plurality of light sources 22 are mounted. The holding member 50 is arranged outside the light cover portion 80 . Accordingly, a plurality of light sources 22 are arranged outside the light cover portion 80 . As a result, it is possible to reduce light emission unevenness that occurs in the light cover portion 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。 Also, the holding member 50 is arranged outside the light cover portion 80 . Therefore, it is possible to smoothly attach and detach the mounting member 21 to and from the holding member 50 while the inside C of the optical cover portion 80 is closed. That is, in a state in which the pair of second blocking members 40 are 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 performed smoothly. As a result, the ease of assembly 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。 Next, the light source unit U2 when attached to the base member 11 will be described with reference to FIG.

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 portion 80 is arranged outside the base member 11 with the light source unit U2 attached to 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。 The entrance portion 90 (the first entrance body 91 and the second entrance body 92) is arranged in the interior C of the base member 11 with the light source unit U2 attached to the base member 11. As shown in FIG.

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。 The holding member 50 is arranged in the interior C of the base member 11 with the light source unit U<b>2 attached to 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 in the interior C of the base member 11 with the light source unit U2 attached to 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 U<b>2 attached to the base member 11 , the space E is arranged in the interior C of the base member 11 . The inside D of the light cover portion 80 is arranged outside the base member 11 while the light source unit U2 is attached to 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 U<b>2 attached to the base member 11 , the plurality of light sources 22 face the interior D of the light cover portion 80 and are arranged outside the light cover portion 80 . The plurality of light sources 22 are arranged in the interior C of the base member 11 with the light source unit U<b>2 attached to the base member 11 . With the light source unit U2 attached to the base member 11, the plurality of light sources 22 are arranged so as to intersect the central axis β.

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 inside C of the base member 11 . Therefore, it is possible to arrange the plurality of light sources 22 apart from the light cover portion 80 and reduce uneven light emission occurring in the light cover portion 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 in the interior C of the base member 11, the distance between the plurality of light sources 22 and the lower portion of the light cover portion 80 (third cover portion 80c) can be increased. Therefore, in the lower part of the light cover part 80, the difference between the brightness directly below the light source 22 and the brightness of the surroundings directly below 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 occurrence of a dark portion in a portion positioned between the adjacent light sources 22 in the light cover portion 80, and to prevent the dark portion from occurring in the lower portion of the light cover portion 80. light emission unevenness can be reduced.

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. FIG. 5 is an exploded perspective view showing the mounting member 70. FIG.

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. As shown in FIG. The mounting member 70 is made of synthetic resin, for example. The mounting member 70 is elastically deformable, for example. The mounting member 70 has a body portion 71 , a first engaging portion 72 , a second engaging portion 73 and a contact portion 74 . A first engaging portion 72 , a second engaging portion 73 , and a contact portion 74 are connected to the body portion 71 . In this embodiment, the body portion 71, the first engaging portion 72, the second engaging portion 73, and the contact portion 74 are integrally molded. The body portion 71 has a substantially flat plate shape. The first engaging portion 72 and the second engaging portion 73 are arranged in the second direction Q to face each other with a space therebetween. The first engaging portion 72 and the second engaging portion 73 protrude from the main body portion 71 along the first direction P, respectively.

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 a cross-sectional view showing the holding member 50. As shown in FIG.
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 engagement 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 attachment member 70 is attached to the holding member 50 by fitting the first engaging portion 72 into the space F<b>1 and fitting the second engaging portion 73 into the space F<b>2 .

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 part of the lighting fixture 1. As shown in FIG. Specifically, FIG. 7 is a sectional view of the central portion of the lighting fixture 1 shown in FIG. 1 cut parallel to the first direction P and parallel to the third direction R. As shown in FIG.
FIG. 7 shows the mounting member 70 mounted on the holding member 50 . As shown in FIG. 7, the contact portion 74 contacts the second closing member 40 . Therefore, the mounting member 70 is sandwiched from both sides in the first direction P by the holding member 50 and the second closing member 40 . As a result, the state in which the mounting member 70 is mounted on the holding member 50 can be maintained.

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。 Also, the mounting member 70 faces the mounting member 21 in the first direction P. As shown in FIG. That is, the mounting member 70 faces the end of the mounting member 21 in the first direction P. As shown in FIG. As a result, when the mounting member 21 is slidably 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 the target position. In other words, it is possible to prevent the mounting member 21 from falling out of the mounting member 21 due to excessive sliding. As a result, the mounting member 21 can be smoothly attached to the holding member 50, and the ease of assembly 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 is provided. One of the pair of mounting members 70 is mounted on the end of the holding member 50 on one side P1 in the first direction P. As shown in FIG. The other one of the pair of mounting members 70 is mounted on the end portion 50a of the holding member 50 on the other side P2 in the first direction P. As shown in FIG. As a result, the pair of mounting members 70 can sandwich the holding member 50 and the mounting member 21 from both sides in the first direction P to hold the holding member 50 and the mounting member 21 .

（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 this embodiment, the holding member 50 that holds the mounting member 21 is provided in the entry portion 90 . The mounting member 21 and the optical cover portion 80 are configured to be detachable from the base member 11 via the mounting member 60 . However, the invention is not so limited. A holding portion that holds the mounting member 21 may be provided on the base member 11 . In this case, the mounting member 21 is configured to be detachable from the base member 11 via the holding portion. The light cover portion 80 is configured to be detachable 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 light 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, the plurality of light sources 22 are arranged in a row along the first direction P. As shown in FIG. However, the invention is not so limited. A plurality of light sources 22 may be arranged along the first direction P in a plurality of rows. However, arranging the plurality of light sources 22 in a row as in this 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。 Also, when the plurality of light sources 22 are arranged in a plurality of rows, the plurality of light sources 22 may come close to the sides of the light cover portion 80 (the first cover portion 80a and/or the second cover portion 80b). On the other hand, as in the present embodiment, the 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. 22 can be prevented from coming close to the side portion of the optical cover portion 80 . As a result, it is possible to effectively suppress the generation of dark portions of the plurality of light sources 22 on the side portion 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。 INDUSTRIAL APPLICABILITY The present invention provides a light source unit and a lighting fixture, and has industrial applicability.
