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 lighting fixture.

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。   With reference to Fig.8 (a)-FIG.8 (c), the illuminating device 100 of patent document 1 is demonstrated. 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 viewed from the W1 direction. FIG. 8C is a view of the diffusion cover 110 shown in FIG. 8A viewed from the W2 direction. As illustrated in FIG. 8A, the lighting device 100 includes a diffusion cover 110, a reflection plate 120, and an LED 130. An LED 130 is disposed inside the diffusion cover 110. A power supply unit is disposed inside the reflector 120. The diffusion cover 110 can be attached to and detached from the reflection plate 120. The diffusion cover 110 transmits and emits the light L emitted from the LED 130.

特開２０１５−００２１６１号公報JP2015-002161A

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 from the LED 130 at an angle of approximately 120 degrees. Therefore, when the LED 130 is disposed inside the diffusion cover 110, the light L emitted from the LED 130 may not easily 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 spreading sufficiently. In this case, the transmission amount of the light L is reduced at the upper part of the diffusion cover 110. Accordingly, a dark portion Z1 is generated at the upper portion of the diffusion cover 110. The dark part Z1 is a dark part compared with the part (bright part Z2) where the light L reaches | attains sufficiently in the diffusion cover 110. FIG. Therefore, when the dark portion Z1 is generated, light emission unevenness occurs in the upper portion of the diffusion cover 110. The uneven light emission is the occurrence of contrast between the dark part Z1 and the bright part 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。   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 at the lower portion of the diffusion cover 110. Specifically, when the diffusion cover 110 is viewed from the W2 direction (downward), a dark portion Z3 is generated at a location located between the adjacent LEDs 130 in the diffusion cover 110. The dark part Z3 occurs for the following reason. In general, when the LED 130 emits light downward, the area immediately below the LED 130 becomes darker than just below the LED 130. That is, the area directly below the LED 130 is brightest. In addition, since the illuminance immediately below the LED is inversely proportional to the distance from the LED to the irradiation surface, the difference between the brightness just below the LED 130 and the brightness just below the LED 130 becomes larger in a position closer to the LED 130 in the optical axis direction. 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 just below the LED 130 and the brightness just below the LED 130 becomes large, and a dark part Z3 is generated below 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 aesthetic appearance of the diffusion cover 110 in the light emission state may be impaired. In particular, 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 residence), there is a desire to install a lighting device with a beautiful appearance with reduced light emission unevenness. Reducing light emission unevenness means that the brightness of the dark part Z1 is made closer to the brightness of the bright part Z2, and / or the area occupied by the dark part Z1 is reduced in the outer surface of the diffusion cover (light cover part) 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-described problems, and an object thereof is to provide a light source unit and a lighting fixture that can reduce 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 lighting fixture 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 shape in cross section. A first opening 14 is formed in the base member 11. The first opening 14 is located at the end of the base member 11 on the other side R2 in the third direction R. 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 an end portion on the other side R2 in the third direction R of the first base portion 11a. The second end portion 11e is an end portion on 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 light cover portion 80 has, for example, a substantially U shape in sectional view. The light cover unit 80 covers the plurality of light sources 22. The light cover portion 80 is located on the other side R2 in the third direction R with respect to the plurality of light sources 22. Accordingly, the light cover 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 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 light cover portion 80 on the one side R1 in the third direction R. The second opening 81 is a region between the third end portion 80d and the fourth end portion 80e. The third end portion 80d is an end portion on the one side R1 in the third direction R of the first cover portion 80a. The fourth end portion 80e is an end portion on one side R1 of the third direction R in the second cover portion 80b. The second opening 81 communicates the inside D of the light cover unit 80 with the outside of the light cover unit 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). Specifically, the dimension α1 indicates the dimension from the outer side of the third end 80d to the outer side of the fourth end 80e. Specifically, the dimension α2 indicates a dimension from the outer portion of the first end portion 11d to the outer portion of the second end portion 11e. Accordingly, when the light source unit U2 is mounted on 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, the light cover portion 80 is restricted from entering the inside C of the base member 11. That is, the light 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 entry part 90 is connected to the light cover part 80. The entry part 90 protrudes from the light cover part 80 to the outside of the light cover part 80. Specifically, the entry portion 90 is connected to the edge portion of the second opening 81. The entry portion 90 protrudes from the edge 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。 In this embodiment, the entry portion 90 is integrally formed with the light cover portion 80. Therefore, the entrance part 90 and the light cover part 80 are comprised with the same material.
The entry portion 90 may be configured separately from the light cover portion 80 and the entry 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 material that transmits light, whereas the entry portion 90 is made of a material that does not transmit light. That is, it is sufficient that at least the light cover unit 80 transmits light among the light cover unit 80 and the entry unit 90.

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 inside C of the base member 11. Specifically, the entry 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 unit 90 includes a first approach body 91 and a second approach body 92.

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 entry body 91 and the second entry body 92 protrude from the light cover portion 80 to the outside of the light cover portion 80.
The first entering body 91 and the second entering body 92 are closer to each other as they are separated from the first cover portion 80a. Each of the first entry body 91 and the second entry body 92 has a shape that bends at a substantially right angle at a plurality of locations. Therefore, the 1st approach body 91 and the 2nd approach body 92 approach mutually in steps, so that it leaves | separates from the 1st cover part 80a.
The first distal end portion 94a of the first entry body 91 and the second distal end portion 94b of the second entry body 92 protrude along the second direction Q toward the central axis β.

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 entry 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 a dimension from the outer side portion of the first base end portion 93a to the outer side portion of the second base end portion 93b. Accordingly, the entry portion 90 (the first entry body 91 and the second entry body 92) is formed so as to be able to enter the interior C of the base member 11.

The void E is disposed outside the light cover unit 80. The void E communicates with the inside D of the light cover portion 80. Specifically, the void E communicates with the inside D of the light cover portion 80 through the second opening 81. In the space E, a plurality of light sources 22 are arranged. A mounting member 21 is disposed in the 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 disposed outside the light cover portion 80.
The holding member 50 is attached to the entry portion 90. The holding member 50 is attached to the entry portion 90. For example, (a) the holding member 50 is detachably attached to the entry portion 90, (b) the holding member 50 is fixed to the entry portion 90, or (C) means that the holding member 50 and the entry portion 90 are integrally formed. In the present embodiment, the holding member 50 is detachably attached to the entry portion 90.

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 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 supports the mounting member 21 so as to be slidable along the first direction P. 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 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.
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 22 b is a surface of the light source 22 that faces the mounting member 21. Accordingly, the light source attachment surface 22 b of the light source 22 is attached to the mounting member 21.
The light emitting surface 22a is disposed on the back side of the light source mounting surface 22b. The side surface 22c is disposed between the light emitting surface 22a and the light source mounting surface 22b.
The light emitting surface 22 a is a surface that emits light in the light source 22. Therefore, the light source 22 of the present embodiment emits light from the light emitting surface 22a among 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 disposed outside the light cover unit 80. Specifically, the light emitting surface 22 a of the light source 22 faces the inside D of the light cover unit 80 and is disposed outside the light cover unit 80. Accordingly, 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.
In the present embodiment, specifically, 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. The light source 22 emits light from the light emitting surface 22 a to the inside D of the light cover unit 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 attachment surface 53 is a back surface of the holding member 50 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 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 attachment 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 where the entry portion 90 has entered the inside C of the base member 11. Specifically, the attachment member 60 is pressed against the inner surface of the base member 11 by the elasticity of the attachment member 60 in a state where the entry portion 90 has entered the inside C of the base member 11. As a result, 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 attachment body via the base member 11, and is installed on the attachment 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 in which the light source unit U2 is mounted on the base member 11, the light source unit U2 can be pulled to remove the light source unit U2 from the base member 11. That is, the light source unit U <b> 2 can be detached 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, the plurality of light sources 22 face the inside D of the light cover portion 80 and are disposed outside the light cover portion 80. Specifically, each light emitting surface 22 a of the plurality of light sources 22 faces the inside D of the light cover portion 80 and is disposed outside the light cover portion 80. Accordingly, the plurality of light sources 22 can be arranged 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. That is, the light that travels from the light emitting surface 22a of each of the plurality of light sources 22 while spreading at a predetermined angle (for example, 120 degrees) is caused to enter the inside D of the light cover portion 80, so that the first cover portion of the light cover portion 80 is reached. It is possible to reach the vicinity of the upper ends of 80a and the second cover portion 80b. As a result, almost the entire light cover portion 80 can emit light, and uneven light emission that occurs 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。   The holding member 50 holds the mounting member 21 on which the plurality of light sources 22 are mounted. The holding member 50 is disposed outside the light cover portion 80. Accordingly, the plurality of light sources 22 are arranged outside the light cover portion 80. As a result, it is possible to reduce uneven light emission 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。   Further, the holding member 50 is disposed outside the light cover portion 80. Therefore, it is possible to smoothly perform the operation of attaching and detaching the mounting member 21 to the holding member 50 in a state where the inside C of the light cover portion 80 is closed. That is, the work of attaching and detaching the mounting member 21 to the holding member 50 can be smoothly performed in a state where the pair of second closing members 40 are attached to the light cover portion 80. 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。   Next, the light source unit U2 when mounted on 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 unit 80 is disposed outside 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、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。   In a state where the light source unit U <b> 2 is attached to the base member 11, the entry portion 90 (the first entry body 91 and the second entry body 92) is disposed inside 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 U <b> 2 attached to the base member 11, the holding member 50 is disposed inside 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 disposed inside the base member 11 in a state where 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 void E is disposed inside the base member 11. In a state where the light source unit U <b> 2 is attached to the base member 11, the inside D of the light cover unit 80 is disposed 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。   In a state where the light source unit U <b> 2 is mounted on the base member 11, the plurality of light sources 22 face the inside D of the light cover unit 80 and are disposed outside the light cover unit 80. In a state where the light source unit U <b> 2 is mounted on the base member 11, the plurality of light sources 22 are disposed in the inside C of the base member 11. In a state where the light source unit U2 is mounted on the base member 11, the plurality of light sources 22 are arranged so as to cross 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 the base member 11. Accordingly, the plurality of light sources 22 can be arranged apart from the light cover portion 80 to reduce uneven light emission that occurs 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, it is possible to increase the distance between the plurality of light sources 22 and the lower portion (third cover portion 80 c) of the light cover portion 80. Therefore, the difference between the brightness directly below the light source 22 and the brightness directly below the light source 22 can be reduced in the lower portion of the light cover portion 80. As a result, when the light cover portion 80 is viewed from below, it is possible to suppress the occurrence of a dark portion at a position located between the adjacent light sources 22 in the light cover portion 80, and is generated at the lower portion of the light cover portion 80. The uneven light emission 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. 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 50 a 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 can be elastically deformed, for example. The mounting member 70 includes a main body portion 71, a first engagement portion 72, a second engagement portion 73, and a contact portion 74. A first engagement portion 72, a second engagement portion 73, and a contact portion 74 are connected to the main body portion 71. In the present embodiment, the main body portion 71, the first engagement portion 72, the second engagement portion 73, and the contact portion 74 are integrally formed. The main body 71 has a substantially flat plate shape. The first engagement portion 72 and the second engagement portion 73 are disposed to face each other with a space along the second direction Q. 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 is a cross-sectional view showing the 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 is fitted 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 is fitted into the space F2. The mounting member 70 is mounted on the holding member 50 by the first engaging portion 72 being fitted into the space F1 and the second engaging portion 73 being fitted 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 in which the central portion of the luminaire 1 shown in FIG. 1 is cut parallel to the first direction P and parallel to the third direction R.
FIG. 7 shows a state where the mounting member 70 is mounted on the holding member 50. As shown in FIG. 7, the contact portion 74 is in 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 state in which the mounting member 70 is mounted on the holding member 50 can be held.

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 is opposed to 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 mounting the mounting member 21 on the holding member 50 while sliding it, the mounting member 21 can be brought into contact with the mounting member 70 and stopped at the position where the mounting member 21 is aimed. That is, it is possible to prevent the mounting member 21 from sliding too much and falling off the mounting member 21. As a result, the mounting member 21 can be smoothly mounted on the holding member 50, and the assemblability 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 the present embodiment, a pair of mounting members 70 are 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. The other one of the pair of mounting members 70 is mounted on the end 50a of the holding member 50 on the other side P2 in the first direction P. As a result, the pair of mounting members 70 can hold the holding member 50 and the mounting member 21 from both sides in the first direction P and 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-described embodiment, and can be implemented in various modes without departing from the gist thereof (for example, (1) to (2) shown below). In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the above embodiments. For example, some components may be deleted from all the components shown in the embodiment. In order to facilitate understanding, the drawings schematically show each component as a main component, and the number of components shown in the drawings may differ from the actual one due to the convenience of drawing. Moreover, each component shown by said embodiment is an example, Comprising: It does not specifically limit, A various change is possible in the range which does not deviate substantially from the effect of this 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 that holds the mounting member 21 is provided in the entry portion 90. The mounting member 21 and the light cover portion 80 are configured to be detachable from the base member 11 via the mounting member 60. However, the present invention is not limited to this. A holding part that holds the mounting member 21 may be provided in 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 attachment 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 line along the first direction P. However, the present invention is not limited to this. The 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 line 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。   In addition, when the plurality of light sources 22 are arranged in a plurality of rows, the plurality of light sources 22 may be close to the side portion (the first cover portion 80a and / or the second cover portion 80b) of the light cover portion 80. In contrast, as in the present embodiment, the plurality of light sources 22 are arranged in a line along the first direction P, and the plurality of light sources 22 are respectively arranged on the central axis β, whereby the plurality of light sources is arranged. It can suppress that 22 adjoins the side part of the light cover part 80. FIG. As a result, it is possible to effectively suppress the occurrence 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。   The present invention provides a light source unit and a lighting fixture, and has industrial applicability.
