図８（ａ）に示すように、第１突出部１５４は幅Ｌ１のリング状であり、第２突出部１５６は、幅Ｌ３のリング状である。
また、図５に示すように、第１突出部１５４は、幅Ｌ１が器具本体１４０の鍔部１４２の幅Ｌ２と略同一か若干広く形成される。第２突出部１５６の幅Ｌ３は、第１突出部１５４の幅Ｌ１と略同一が好ましい。
図８の（ｃ）及び図１１に示すように、第２突出部１５６は上面、すなわち第１突出部１５４に対向する面が周枠部１５３の内部中心に向かって徐々に傾斜する傾斜面部５６１を形成している。 As shown in FIG. 8A, the first protruding portion 154 has a ring shape having a width L1 and the second protruding portion 156 has a ring shape having a width L3.
Further, as shown in FIG. 5, the width L1 of the first protruding portion 154 is formed to be substantially the same as or slightly wider than the width L2 of the flange portion 142 of the instrument main body 140. The width L3 of the second protruding portion 156 is preferably substantially the same as the width L1 of the first protruding portion 154.
As shown in (c) and 11 of FIG. 8, the second protruding portion 156 has an inclined surface portion 561 whose upper surface, that is, a surface facing the first protruding portion 154 gradually inclines toward the inner center of the peripheral frame portion 153. Is forming.

第１突出部１５４には、嵌め込み部１５１に器具本体１４０の鍔部１４２が嵌め込まれた場合に、器具本体１４０のリブ１４８が挿入されるスリット５４１と、バネ取付部１４７の一部が配置される切欠き部５４２とが形成される。 The first protrusion 154 is provided with a slit 541 into which the rib 148 of the instrument body 140 is inserted when the flange 142 of the instrument body 140 is fitted into the fitting portion 151, and a part of the spring mounting portion 147. A notch portion 542 is formed.

＜カバーの周枠部１５３について＞
カバー１５０は、弾性部材により形成される。また、カバー１５０は、透光性を有する。具体的には、カバー１５０は、シリコーン製である。
シリコーンのような透過性を有する材料は、材料厚みの厚いところが薄いところに比べ、暗くなってしまう傾向がある。本実施の形態では、図７の（ｂ）に示すように、カバー１５０内の明暗差を極力抑えるため、カバー１５０の円筒形上の周枠部１５３の角部５３１は厚みが一定になるようＲ形状としている。
また、カバー１５０内で光が反射するので、肉厚になりやすい周枠部１５３と第１突出部１５４との境目に光が当たり、暗がりになりにくい。 <About the peripheral frame part 153 of the cover>
The cover 150 is formed of an elastic member. Further, the cover 150 has a translucent property. Specifically, the cover 150 is made of silicone.
A permeable material such as silicone tends to be darker in thicker parts than in thinner parts. In the present embodiment, as shown in FIG. 7B, in order to suppress the difference in brightness in the cover 150 as much as possible, the corner portion 531 of the peripheral frame portion 153 on the cylinder of the cover 150 has a constant thickness. It has an R shape.
Further, since the light is reflected inside the cover 150, the light hits the boundary between the peripheral frame portion 153 and the first protruding portion 154, which tend to be thick, and it is difficult for the light to become dark.

周枠部１５３の内周径は鍔部１４２の外周径よりも小さい、或いは、周枠部１５３の内周径と鍔部１４２の外周径とは等しいように形成される。すなわち、周枠部１５３の内周径は、鍔部１４２の外周径と同じか、やや小さくなるように形成されている。なお、鍔部１４２の外周径よりも周枠部１５３の内周径を小さくするのは、嵌め込み部１５１が形成される部分のみでもよい。すなわち、嵌め込み溝１５７の内周径が器具本体１４０の鍔部１４２の外周径よりもやや小さくなっていればよい。すなわち、周枠部１５３全体の内周径を鍔部１４２の外周径よりも小さくする必要はない。要するに、嵌め込み部１５１が鍔部１４２に嵌合したときに、周枠部１５３が外側に広げられ、周枠部１５３が元の形状に戻るように、内側方向に対して応力が発生するようになっていればよい。 The inner peripheral diameter of the peripheral frame portion 153 is smaller than the outer peripheral diameter of the flange portion 142, or the inner peripheral diameter of the peripheral frame portion 153 is formed to be equal to the outer peripheral diameter of the flange portion 142. That is, the inner peripheral diameter of the peripheral frame portion 153 is formed so as to be the same as or slightly smaller than the outer peripheral diameter of the flange portion 142. The inner peripheral diameter of the peripheral frame portion 153 may be smaller than the outer peripheral diameter of the flange portion 142 only at the portion where the fitting portion 151 is formed. That is, the inner peripheral diameter of the fitting groove 157 may be slightly smaller than the outer peripheral diameter of the flange portion 142 of the instrument main body 140. That is, it is not necessary to make the inner peripheral diameter of the entire peripheral frame portion 153 smaller than the outer peripheral diameter of the flange portion 142. In short, when the fitting portion 151 is fitted to the flange portion 142, the peripheral frame portion 153 is expanded outward and stress is generated in the inward direction so that the peripheral frame portion 153 returns to its original shape. It should be.

このように、シリコーン製のカバー１５０の周枠部１５３の内周径を鍔部１４２（反射枠ともいう）の外周径よりも等しいか、やや小さめとする。このようにすることで、カバー１５０を鍔部１４２に取り付けた際、カバー１５０を押し広げるように応力が発生するので、カバー１５０が鍔部１４２から外れ難くすることができる。
また、周枠部１５３によって、光を拡散することができる。図６の矢印Ｑ４に示すように、照明器具３０を天井に取り付けた際、天井面方向に光を照射することができ、天井面を明るくすることができる。またカバー１５０を均一に明るくすることもできる。これにより、天井面とカバー１５０との輝度差を小さくすることができるので、グレアを抑制することができる。 As described above, the inner peripheral diameter of the peripheral frame portion 153 of the silicone cover 150 is equal to or slightly smaller than the outer peripheral diameter of the flange portion 142 (also referred to as the reflection frame). By doing so, when the cover 150 is attached to the collar portion 142, stress is generated so as to spread the cover 150, so that the cover 150 can be prevented from coming off from the collar portion 142.
In addition, the peripheral frame portion 153 can diffuse the light. As shown by the arrow Q4 in FIG. 6, when the luminaire 30 is attached to the ceiling, it is possible to irradiate light toward the ceiling surface and brighten the ceiling surface. The cover 150 can also be uniformly brightened. As a result, the difference in brightness between the ceiling surface and the cover 150 can be reduced, so that glare can be suppressed.

＜カバー１５０の底部１５５について＞
底部１５５は、中央部５５１が取付側に凹むように、曲面状をなしている。
図６に示すように、底部１５５において中央部５５１を凹ますことで、光源部１２０の発光部１２２と中央部５５１との距離Ｌ４が近くなり、直下方向への光の透過量が多くなる。よって、ダウンライトである照明装置１０の直下方向の照度を高めることができる。
また、図９の（ｂ）に示すように、カバー１５０を器具本体１４０の鍔部１４２に取り付けた際、カバー１５０の周枠部１５３が外方へ引っ張られる応力Ｑ３が発生する。しかし、底部１５５を凹状に形成することで、この底部１５５の凹状が変形し、応力Ｑ３と均衡した状態となる。よって、カバー１５０の周枠部１５３が内側方向へ形状が変形する変形量を抑えることができる。また、凹状の形状が若干変形しても、照明装置１０としての意匠性を保つことができる。つまり、発光部１２２を覆う部分（底部１５５の部分）が平面であると、応力Ｑ３により発光部１２２を覆う部分が変形した場合、平面から窪んだ状態に変形してしまうため、意匠面の形状変化が現れる。しかし、元々凹状に形成しているので、意匠面の形状変化が少なく、意匠性を保つことができる。 <About the bottom 155 of the cover 150>
The bottom portion 155 has a curved surface shape so that the central portion 551 is recessed toward the mounting side.
As shown in FIG. 6, by recessing the central portion 551 at the bottom portion 155, the distance L4 between the light emitting portion 122 of the light source portion 120 and the central portion 551 becomes closer, and the amount of light transmitted in the direct downward direction increases. Therefore, the illuminance in the direction directly below the lighting device 10 which is a downlight can be increased.
Further, as shown in FIG. 9B, when the cover 150 is attached to the flange portion 142 of the instrument main body 140, a stress Q3 is generated in which the peripheral frame portion 153 of the cover 150 is pulled outward. However, by forming the bottom portion 155 into a concave shape, the concave shape of the bottom portion 155 is deformed, and the state is in equilibrium with the stress Q3. Therefore, it is possible to suppress the amount of deformation in which the peripheral frame portion 153 of the cover 150 is deformed inward. Further, even if the concave shape is slightly deformed, the design of the lighting device 10 can be maintained. That is, if the portion covering the light emitting portion 122 (the portion of the bottom portion 155) is flat, when the portion covering the light emitting portion 122 is deformed by the stress Q3, the portion covering the light emitting portion 122 is deformed from the flat surface to a recessed state, so that the shape of the design surface is formed. Changes appear. However, since it is originally formed in a concave shape, there is little change in the shape of the design surface, and the design can be maintained.

＜カバーの嵌め込み部１５１について＞
図９の（ｂ）及び図１１に示すように、嵌め込み部１５１は、鍔部１４２に取り付けられた際、鍔部１４２を挟み込む或いは包み込むような「コ」の字状、「Ｕ」字状或いは「Ｖ」字状に形成されている。すなわち、嵌め込み溝１５７の断面形状が、鍔部１４２を挟み込む或いは包み込むような「コ」の字状、「Ｕ」字状或いは「Ｖ」字状となる。 <About the fitting part 151 of the cover>
As shown in FIG. 9B and FIG. 11, the fitting portion 151 has a "U" shape, a "U" shape, or a "U" shape that sandwiches or wraps the collar portion 142 when attached to the collar portion 142. It is formed in a "V" shape. That is, the cross-sectional shape of the fitting groove 157 is a "U" shape, a "U" shape, or a "V" shape that sandwiches or wraps the collar portion 142.

上述したように、嵌め込み部１５１は、第１突出部１５４と、第２突出部１５６と、第１突出部１５４と第２突出部１５６とを連結する連結部１５８とを有する。連結部１５８は周枠部１５３の一部であってもよい。第１突出部１５４は、一端部の縁部から内側に向かって突出し、鍔部１４２に接している。また、第２突出部１５６は、周枠部１５３の内壁から内側に向かって形成され、鍔部１４２に接していると共に第１突出部１５４との間に鍔部１４２を嵌め込む。 As described above, the fitting portion 151 has a first protruding portion 154, a second protruding portion 156, and a connecting portion 158 that connects the first protruding portion 154 and the second protruding portion 156. The connecting portion 158 may be a part of the peripheral frame portion 153. The first protruding portion 154 projects inward from the edge portion of one end portion and is in contact with the flange portion 142. Further, the second protruding portion 156 is formed inward from the inner wall of the peripheral frame portion 153, is in contact with the flange portion 142, and fits the collar portion 142 between the second protruding portion 154 and the first protruding portion 154.

第１突出部１５４は、鍔部１４２のうち、反射部１４１が天井面の埋め込み穴に挿入されたとき、天井面側の上面４２２に接触する。第１突出部１５４は上面支持部ともいう。第１突出部１５４は、鍔部１４２から外れ難くするため、鍔部１４２との重なり量が大きくなるように形成されている。第１突出部１５４の幅Ｌ１は、鍔部１４２の幅Ｌ２と略同一に形成されることが好ましい。 The first protruding portion 154 comes into contact with the upper surface 422 on the ceiling surface side when the reflecting portion 141 of the flange portion 142 is inserted into the embedded hole on the ceiling surface. The first protruding portion 154 is also referred to as an upper surface support portion. The first protruding portion 154 is formed so as to have a large amount of overlap with the flange portion 142 in order to prevent the first protruding portion 154 from coming off the flange portion 142. It is preferable that the width L1 of the first protruding portion 154 is formed substantially the same as the width L2 of the flange portion 142.

第２突出部１５６は、鍔部１４２のうち、上面４２２とは反対側に形成される下面４２１に接触する。第２突出部１５６は下面支持部ともいう。第２突出部１５６は、第１突出部１５４と共に鍔部１４２を挟み込む機能を有する。
図１１に示すように、照明器具３０の反射部１４１が天井面に形成された埋め込み穴に取り付けられた場合、天井面における埋め込み穴の周縁と鍔部１４２との間に第１突出部１５４が挟まれるので、カバー１５０が鍔部１４２から外れることはない。よって、第２突出部１５６は必須ではない。しかし、反射部１４１が天井面の埋め込み穴から外されたとき、第１突出部１５４は天井面に接触することがなくなるので、鍔部１４２の上面４２２への接触ができなくなる。よって、これを解消するために、第２突出部１５６により鍔部１４２の下面４２１を支持して、第１突出部１５４が鍔部１４２の上面４２２へ接触することを補助している。 The second protruding portion 156 comes into contact with the lower surface 421 of the collar portion 142 formed on the side opposite to the upper surface 422. The second protruding portion 156 is also referred to as a lower surface support portion. The second protruding portion 156 has a function of sandwiching the flange portion 142 together with the first protruding portion 154.
As shown in FIG. 11, when the reflective portion 141 of the luminaire 30 is attached to the embedded hole formed in the ceiling surface, the first protruding portion 154 is formed between the peripheral edge of the embedded hole and the flange portion 142 on the ceiling surface. Since it is sandwiched, the cover 150 does not come off from the collar 142. Therefore, the second protrusion 156 is not essential. However, when the reflecting portion 141 is removed from the embedded hole on the ceiling surface, the first protruding portion 154 does not come into contact with the ceiling surface, so that the flange portion 142 cannot come into contact with the upper surface 422. Therefore, in order to eliminate this, the lower surface 421 of the collar portion 142 is supported by the second protrusion 156, and the first protrusion 154 is assisted in contacting the upper surface 422 of the collar portion 142.

連結部１５８は、第１突出部１５４と第２突出部１５６とを繋げるための機能を有する。つまり、連結部１５８は、周枠部１５３の一部であってもよいし、第１突出部１５４と第２突出部１５６とを直接連結するようにしてもよい。よって、連結部１５８の形状は特定の形状に限定されない。 The connecting portion 158 has a function for connecting the first protruding portion 154 and the second protruding portion 156. That is, the connecting portion 158 may be a part of the peripheral frame portion 153, or the first protruding portion 154 and the second protruding portion 156 may be directly connected. Therefore, the shape of the connecting portion 158 is not limited to a specific shape.

なお、上記の周枠部１５３の説明では、鍔部１４２の外周径と周枠部１５３の内周径との関係から、周枠部１５３に応力を発生する場合について述べた。ここでは、鍔部１４２の外周径と周枠部１５３の内周径との関係ではなく、嵌め込み部１５１を工夫することによって、カバー１５０が器具本体１４０の鍔部１４２から外れないように固定力を高めてもよい。
具体的には、嵌め込み部１５１が鍔部１４２に当接した際に、嵌め込み部１５１が押し広げられるようにしてもよい。また、嵌め込み部１５１と鍔部１４２との接触面を大きくしたり、引っ掛かり部を設けてもよい。この場合は、周枠部１５３の内周径は、必ずしも鍔部１４２の外周径よりも小さくする必要はない。 In the above description of the peripheral frame portion 153, a case where stress is generated in the peripheral frame portion 153 has been described from the relationship between the outer peripheral diameter of the flange portion 142 and the inner peripheral diameter of the peripheral frame portion 153. Here, rather than the relationship between the outer peripheral diameter of the flange portion 142 and the inner peripheral diameter of the peripheral frame portion 153, by devising the fitting portion 151, the cover 150 is fixed so as not to come off from the flange portion 142 of the instrument main body 140. May be increased.
Specifically, when the fitting portion 151 comes into contact with the flange portion 142, the fitting portion 151 may be pushed open. Further, the contact surface between the fitting portion 151 and the flange portion 142 may be enlarged, or a hooking portion may be provided. In this case, the inner peripheral diameter of the peripheral frame portion 153 does not necessarily have to be smaller than the outer peripheral diameter of the flange portion 142.

以上のように、カバー１５０の嵌め込み部１５１において、器具本体１４０の鍔部１４２へ重なる部分を多くすることで、カバー１５０の鍔部１４２に対する嵌合力を高めている。
また、嵌め込み部１５１の変形例として、図１１の（ｂ）に示すように、第２突出部１５６において鍔部１４２と重なる部分にリング状の凸部５６２を鍔部１４２方向に設ける。また、図１１の（ｂ）に示すように、鍔部１４２の下面４２１において凸部５６２と重なる部分にリング状の凹み４２５を設ける。このような凸部５６２と凹み４２５を設けることにより、カバー１５０が鍔部１４２から外れ難くすることができる。
また、嵌め込み部１５１の変形例として、図１１の（ｃ）に示すように、第１突出部１５４において鍔部１４２と重なる部分にリング状の凸部５６３を鍔部１４２方向に設けてもよい。この凸部５６３が鍔部１４２の上面４２２と接することにより、カバー１５０が鍔部１４２から外れ難くすることができる。 As described above, the fitting force of the cover 150 with respect to the flange portion 142 is increased by increasing the portion of the fitting portion 151 of the cover 150 that overlaps the flange portion 142 of the instrument main body 140.
Further, as a modification of the fitting portion 151, as shown in FIG. 11B, a ring-shaped convex portion 562 is provided in the portion of the second protruding portion 156 that overlaps the collar portion 142 in the direction of the collar portion 142. Further, as shown in FIG. 11B, a ring-shaped recess 425 is provided in a portion of the lower surface 421 of the collar portion 142 that overlaps with the convex portion 562. By providing such a convex portion 562 and a concave portion 425, the cover 150 can be made difficult to come off from the flange portion 142.
Further, as a modification of the fitting portion 151, as shown in FIG. 11C, a ring-shaped convex portion 563 may be provided in the portion of the first protruding portion 154 that overlaps the collar portion 142 in the direction of the collar portion 142. .. When the convex portion 563 comes into contact with the upper surface 422 of the flange portion 142, the cover 150 can be made difficult to come off from the flange portion 142.

また、カバー１５０の嵌め込み部１５１に鍔部１４２が嵌め込まれているので、照明装置１０を天井面に取り付けた際、カバー１５０が天井面へ当接する（図１１の（ａ）参照）。カバー１５０はシリコーンのように弾性力を有する材料で形成されており、弾力性を持っているので、カバー１５０と天井面との間に隙間が生じ難い。これは、カバー１５０が弾性変形することで、天井面との密着性を高めることができるからである。また、カバー１５０が天井面と密着することにより、照明装置１０を天井面に取り付けた際、カバー１５０が照明器具３０から外れ難くすることができる。 Further, since the flange portion 142 is fitted into the fitting portion 151 of the cover 150, the cover 150 comes into contact with the ceiling surface when the lighting device 10 is attached to the ceiling surface (see (a) in FIG. 11). Since the cover 150 is made of an elastic material such as silicone and has elasticity, it is unlikely that a gap is formed between the cover 150 and the ceiling surface. This is because the cover 150 is elastically deformed, so that the adhesion to the ceiling surface can be improved. Further, since the cover 150 is in close contact with the ceiling surface, the cover 150 can be prevented from coming off from the lighting fixture 30 when the lighting device 10 is attached to the ceiling surface.

また、照明器具３０は、鍔部１４２から第１突出部１５４の側に突き出たリブ１４８を有し、第１突出部１５４は、リブ１４８が入り込んだスリット５４１を有する。図１０に示すように、第１突出部１５４には、反射部１４１に形成されたリブ１４８が挿入されるスリット５４１が形成されると共に、バネ取付部１４７の一部が挿入される切欠き部５４２が形成される。
照明装置１０を天井から外す際、作業者は、カバー１５０を挟持し、引き下げる方向に引っ張ることで取り外しを行う。このとき、作業者がカバー１５０を挟持した状態で回転方向（図１の（ｂ）のＱ５方向）に回してしまうと、カバー１５０が照明器具３０の鍔部１４２の周りを空転してしまう虞がある。
本実施の形態に係るカバー１５０によれば、反射部１４１に形成されているリブ１４８が入り込むスリット５４１を設けているので、回転方向にカバー１５０を回しても、鍔部１４２の周りを空転しないようにすることができる。作業者が回転方向にカバー１５０を回転させる場合、スリット５４１に反射部１４１のリブ１４８が入り込んでいるので、器具本体１４０全体を回転させることができる。例えば、天井材に当接している取付バネ１４６が天井材に噛み合ってしまって、照明装置１０を天井材から引き下げ難い場合がある。このような場合に、本実施の形態に係る照明器具３０によれば、作業者は、照明装置１０全体を回転方向へ右回転、左回転とグリグリと揺さぶる（右へ左へと回転動作をさせる）ことにより、強固に嵌合している状態を緩和させることができる。 Further, the luminaire 30 has a rib 148 protruding from the flange portion 142 toward the first protruding portion 154, and the first protruding portion 154 has a slit 541 in which the rib 148 has entered. As shown in FIG. 10, the first protruding portion 154 is formed with a slit 541 into which the rib 148 formed in the reflecting portion 141 is inserted, and a notch portion into which a part of the spring mounting portion 147 is inserted. 542 is formed.
When removing the lighting device 10 from the ceiling, the operator holds the cover 150 and pulls it in the pulling direction to remove the lighting device 10. At this time, if the operator turns the cover 150 in the rotation direction (Q5 direction in FIG. 1B) while holding the cover 150, the cover 150 may slip around the flange portion 142 of the lighting fixture 30. There is.
According to the cover 150 according to the present embodiment, since the slit 541 in which the rib 148 formed in the reflection portion 141 enters is provided, even if the cover 150 is rotated in the rotation direction, the cover 150 does not slip around the collar portion 142. Can be done. When the operator rotates the cover 150 in the rotation direction, the rib 148 of the reflecting portion 141 is inserted in the slit 541, so that the entire instrument main body 140 can be rotated. For example, the mounting spring 146 that is in contact with the ceiling material may mesh with the ceiling material, making it difficult to pull down the lighting device 10 from the ceiling material. In such a case, according to the luminaire 30 according to the present embodiment, the operator rotates the entire illuminating device 10 clockwise, counterclockwise, and shakes (rotates to the right and left). ), It is possible to relax the tightly fitted state.

＜鍔部１４２と嵌め込み部１５１との嵌合状態について＞
図１１の（ａ）に示すように、鍔部１４２は、周縁に向かって徐々に上方に傾斜する傾斜部４２７を形成している。また、嵌め込み部１５１の第２突出部１５６は、この傾斜部４２７に沿って傾斜する傾斜面部５６１を有する。傾斜面部５６１の傾斜は、傾斜部４２７の傾斜より、若干きつい傾斜であることが好ましい。これにより、第２突出部１５６により鍔部１４２を第１突出部１５４側に適度に押し付けることができる。よって、鍔部１４２に対するカバー１５０の取り付けを強固にすることができる。
また、鍔部１４２に傾斜部４２７を形成し、この傾斜部４２７に傾斜面部５６１が適度に接するようにしているので、強い振動などによって挟み込み状態が解除されることを防ぐことができる。 <About the fitting state of the flange portion 142 and the fitting portion 151>
As shown in FIG. 11A, the collar portion 142 forms an inclined portion 427 that gradually inclines upward toward the peripheral edge. Further, the second protruding portion 156 of the fitting portion 151 has an inclined surface portion 561 that is inclined along the inclined portion 427. The inclination of the inclined surface portion 561 is preferably slightly steeper than the inclination of the inclined portion 427. As a result, the flange portion 142 can be appropriately pressed against the first protruding portion 154 by the second protruding portion 156. Therefore, the attachment of the cover 150 to the flange portion 142 can be strengthened.
Further, since the inclined portion 427 is formed on the flange portion 142 so that the inclined surface portion 561 is appropriately in contact with the inclined portion 427, it is possible to prevent the pinched state from being released due to strong vibration or the like.

＊＊＊他の構成＊＊＊
本実施の形態では、底部１５５は凹部を形成しているとしたが、底部１５５が嵌め込み部１５１から離れる方向に突き出た凸状でもよい。また、底部１５５は、平面状であってもよい。その他、底部１５５が凹凸を有する形状でも構わない。 *** Other configurations ***
In the present embodiment, the bottom portion 155 is said to have a concave portion, but the bottom portion 155 may have a convex shape protruding in a direction away from the fitting portion 151. Further, the bottom portion 155 may be flat. In addition, the bottom portion 155 may have an uneven shape.

また、本実施の形態では、鍔部１４２は略円形であり、周枠部１５３も端面が略円形の円筒形状を例に説明した。しかし、鍔部は楕円形、多角形、不定形等でもよく、この場合は鍔部の形状に合わせてカバーの周枠部も端面が楕円形、多角形、不定形等の筒形状でもよい。 Further, in the present embodiment, the flange portion 142 has a substantially circular shape, and the peripheral frame portion 153 also has a cylindrical shape having a substantially circular end face. However, the collar portion may have an elliptical shape, a polygonal shape, an amorphous shape, or the like. In this case, the peripheral frame portion of the cover may also have a tubular shape such as an elliptical shape, a polygonal shape, or an amorphous shape according to the shape of the collar portion.

また、本実施の形態では、周枠部１５３の側部１５２が筒形状であるとしたが、周枠部１５３の側部１５２が嵌め込み部１５１から底部１５５に向かって広がるように形成されていてもよい。また、周枠部１５３の側部１５２が嵌め込み部１５１から底部１５５に向かって狭くなるように形成されていてもよい。また、周枠部１５３の側部１５２に凹状部或いは凸状部が形成されていても構わない。 Further, in the present embodiment, the side portion 152 of the peripheral frame portion 153 has a tubular shape, but the side portion 152 of the peripheral frame portion 153 is formed so as to expand from the fitting portion 151 toward the bottom portion 155. May be good. Further, the side portion 152 of the peripheral frame portion 153 may be formed so as to narrow from the fitting portion 151 toward the bottom portion 155. Further, a concave portion or a convex portion may be formed on the side portion 152 of the peripheral frame portion 153.

＊＊＊本実施の形態の効果の説明＊＊＊
以上のように、本実施の形態に係るカバーによれば、周枠部によって光を拡散し、天井面方向にも光を照射することができるので、天井面を明るくすることができる。また、本実施の形態に係るカバーによれば、底部１５５に凹部を有するので、照明装置の直下方向の照度を高めることができる。 *** Explanation of the effect of this embodiment ***
As described above, according to the cover according to the present embodiment, the light can be diffused by the peripheral frame portion and the light can be irradiated toward the ceiling surface, so that the ceiling surface can be brightened. Further, according to the cover according to the present embodiment, since the bottom portion 155 has a recess, the illuminance in the direction directly below the lighting device can be increased.

また、本実施の形態に係るカバーは、嵌め込み部が照明器具の鍔部を覆った状態で照明器具に取り付けられるので、嵌め込み部が弾性変形することで、天井面との密着性を高めることができる。また、カバーが天井面と密着することにより、照明器具を天井面に取り付けた際、カバーを照明器具から外れ難くすることができる。 Further, since the cover according to the present embodiment is attached to the luminaire with the fitting portion covering the flange portion of the luminaire, the fitting portion is elastically deformed to improve the adhesion to the ceiling surface. it can. Further, since the cover is in close contact with the ceiling surface, it is possible to prevent the cover from coming off from the lighting fixture when the lighting fixture is attached to the ceiling surface.

また、本実施の形態に係るカバー１５０では、周枠部の内周径と鍔部の外周径とが略等しいか、或いは周枠部の内周径が鍔部の外周径よりもやや小さめである。このため、カバーを鍔部に取り付けた際、カバーが押し広げられるように応力が発生し、カバーが鍔部から外れ難くすることができる。また、本実施の形態に係るカバーによれば、底部１５５に凹部を有するので、カバーが押し広げられるように応力が発生した場合の形状変化を目立たなくでき、意匠性を保つことができる。 Further, in the cover 150 according to the present embodiment, the inner peripheral diameter of the peripheral frame portion and the outer peripheral diameter of the flange portion are substantially equal to each other, or the inner peripheral diameter of the peripheral frame portion is slightly smaller than the outer peripheral diameter of the collar portion. is there. Therefore, when the cover is attached to the collar portion, stress is generated so that the cover is spread out, and the cover can be made difficult to come off from the collar portion. Further, according to the cover according to the present embodiment, since the bottom portion 155 has a recess, the shape change when stress is generated so that the cover can be expanded can be made inconspicuous, and the design can be maintained.

また、本実施の形態に係るカバー１５０によれば、リブが挿入されるスリットや、バネ取付部がの一部が配置される切欠き部を有するので、作業者が周枠部を挟持してカバーを回転させた場合でもカバーが空転することなく、照明器具全体を回転させることができる。よって、作業性を向上させることができる。 Further, according to the cover 150 according to the present embodiment, since the cover 150 has a slit into which the rib is inserted and a notch portion in which a part of the spring mounting portion is arranged, the operator sandwiches the peripheral frame portion. Even when the cover is rotated, the entire luminaire can be rotated without the cover idling. Therefore, workability can be improved.
