The opening 62 is formed at a position corresponding to the mounting hole 24 of the housing portion 23. A notch 67 is formed in the opening 62 so as not to interfere with the night light 28. The notch 67 also has a positioning function when the protection member 61 is attached to the instrument main body 21. A first abutting portion 63 that abuts on the first protection member abutting surface 26 of the instrument main body 21 in a state where the protection member 61 is attached to the instrument main body 21 is formed at the edge of the opening 62 and the notch 67. ing.

平坦部６５は、開口部６２から外周側に向けて形成される部分である。曲面部６６は、平坦部６５から外周側に向けて湾曲して形成される部分である。曲面部６６の外周側の縁部には、保護部材６１を器具本体２１に取り付けた状態で、器具本体２１の第２保護部材当接面２７に当接する第２当接部６４が形成されている。   The flat portion 65 is a portion formed from the opening 62 toward the outer peripheral side. The curved surface portion 66 is a portion that is curved from the flat portion 65 toward the outer peripheral side. A second abutment portion 64 that abuts against the second protection member abutment surface 27 of the instrument main body 21 in a state where the protection member 61 is attached to the instrument main body 21 is formed at the outer peripheral edge of the curved surface portion 66. Yes.

保護部材６１の外周側には、保護部材６１と器具本体２１とを固定するための固定部６８が設けられている。固定部６８は、保護部材６１を器具本体２１に取り付けた状態で、器具本体２１と略平行となる平面状の部分である。固定部６８には、ボルト７１Ａを通すための孔６９が形成されている。保護部材６１と器具本体２１との固定には、上述のＬＥＤ光源モジュール４４を光源取付部２２に固定するためのボルト７１Ａが兼用して用いられる。固定部６８付近では、曲面部６６の形状は、固定部６８に滑らかに連続するように谷状に形成されている。   A fixing portion 68 for fixing the protection member 61 and the instrument main body 21 is provided on the outer peripheral side of the protection member 61.

L1 is set to L1, and as shown in FIG. 5A, when the height difference between the first contact portion 63 and the second contact portion 64 of the protection member 61 is L2, L2 is set slightly shorter than L1. . For this reason, when the protection member 61 is attached to the instrument main body 21 with the bolt 71A, as shown in FIG. 2, the flat portion 65 and the curved surface portion 66 are mainly elastically deformed, and the flat portion 65 and the curved surface portion 66 are restored to their original shapes. The first abutting portion 63 is pressed against the housing portion 23 of the instrument body 21 by the force to return.

以上説明した本実施形態に係る照明器具１１によれば、次のような効果を有する。   According to the lighting fixture 11 which concerns on this embodiment demonstrated above, it has the following effects.

照明器具１１は、器具本体２１とセード５１との間において、光源部４１を覆うように配置され、器具本体２１との間に空間を形成する透光性の保護部材６１を備える。このため、セード５１を外した状態でも光源部４１が露出せず、使用者が不用意に基板４３やＬＥＤ４２に接触し、静電気や湿気によりＬＥＤ４２の性能が低下することを防止できる。また、セード５１内に侵入した昆虫等が光源部４１に入り込むことを防止できる。   The luminaire 11 includes a translucent protective member 61 that is disposed between the fixture body 21 and the shade 51 so as to cover the light source unit 41 and forms a space between the fixture body 21. For this reason, even if the shade 51 is removed, the light source unit 41 is not exposed, and the user can be prevented from inadvertently coming into contact with the substrate 43 and the LED 42 and the performance of the LED 42 being deteriorated due to static electricity or moisture. In addition, insects or the like that have entered the shade 51 can be prevented from entering the light source unit 41.

照明器具１１の保護部材６１は、取付穴２４に対応する位置に形成される開口部６２と、開口部６２の周囲に形成され、器具本体２１に当接する第１当接部６３と、外周側に形成され、器具本体２１に当接する第２当接部６４と、を備える。このため、器具本体２１に第１当接部６３と第２当接部６４とが当接することで昆虫等が入り込みにくい空間が形成される。   The protection member 61 of the lighting device 11 includes an opening 62 formed at a position corresponding to the mounting hole 24, a first contact portion 63 formed around the opening 62 and contacting the device body 21, and an outer peripheral side. And a second abutting portion 64 that abuts against the instrument main body 21. For this reason, the first contact part 63 and the second contact part 64 are brought into contact with the instrument body 21 to form a space in which insects and the like are difficult to enter.

照明器具１１は、保護部材６１と器具本体２１とを固定するための固定部６８を備え、固定部６８は、保護部材６１の外周側に配置される。外周側の固定部６８によって保護部材６１の取り付け、取り外しができるため、保護部材６１の取り付け、取り外しが容易である。   The lighting fixture 11 includes a fixing portion 68 for fixing the protection member 61 and the fixture main body 21, and the fixing portion 68 is disposed on the outer peripheral side of the protection member 61. Since the protective member 61 can be attached and detached by the fixing portion 68 on the outer peripheral side, the protective member 61 can be easily attached and detached.

照明器具１１は、固定部６８において、保護部材６１と器具本体２１とを固定するとともに、光源部４１を器具本体２１に固定する。固定部６８において保護部材６１と光源部４１が器具本体２１に取り付けられているため、保護部材６１と光源部４１の取り付けが容易である。   The lighting fixture 11 fixes the protection member 61 and the fixture main body 21 at the fixing portion 68 and also fixes the light source portion 41 to the fixture main body 21. Since the protection member 61 and the light source unit 41 are attached to the instrument main body 21 in the fixing unit 68, the protection member 61 and the light source unit 41 can be easily attached.

照明器具１１の保護部材６１は、平坦部６５と、曲面部６６と、を備え、保護部材６１は、器具本体２１に配置された状態において、第１当接部６３が収容部２３に対して付勢された状態、すなわち、平坦部６５と曲面部６６が元の形状に戻ろうとする力により器具本体２１の収容部２３に第１当接部６３が押し付けられる状態で当接している。曲面部６６は湾曲して形成されているため、光源部４１からの光を遮りにくくセード５１に影が出にくい。また、曲面部６６は弾性変形しにくいが、平坦部６５は弾性変形しやすいため、第１当接部６３を収容部２３に対して付勢された状態で当接させることができる。   The protection member 61 of the lighting device 11 includes a flat portion 65 and a curved surface portion 66, and the protection member 61 is arranged such that the first abutting portion 63 is located with respect to the housing portion 23 in a state where the protection member 61 is disposed on the fixture body 21. The first contact portion 63 is in contact with the housing portion 23 of the instrument main body 21 by the biased state, that is, the force that the flat portion 65 and the curved surface portion 66 return to the original shape. Since the curved surface portion 66 is formed to be curved, it is difficult to block the light from the light source portion 41, and it is difficult for a shadow to appear on the shade 51. In addition, the curved surface portion 66 is not easily elastically deformed, but the flat portion 65 is easily elastically deformed. Therefore, the first contact portion 63 can be brought into contact with the housing portion 23 while being urged.

照明器具１１の保護部材６１は、光拡散処理が施されている。このため、光源部４１からの光を拡散させることで、色むらがでにくくなる。   The protective member 61 of the luminaire 11 is subjected to a light diffusion process. For this reason, it is difficult to cause color unevenness by diffusing the light from the light source unit 41.

以上、本発明の実施形態について説明したが、本発明は上記実施例に限定されるものではなく、様々な変更が可能である。例えば、照明器具１１は丸型としたが、角型やその他の形状としてもよい。また、シーリングライトの他、ペンダントライト等に適用してもよい。   As mentioned above, although embodiment of this invention was described, this invention is not limited to the said Example, A various change is possible. For example, although the luminaire 11 is a round shape, it may be a square shape or other shapes. Moreover, you may apply to a pendant light etc. besides a ceiling light.

本実施形態の保護部材６１の形状は一例であり、本実施形態の形状に限定されるものではない。例えば、照明器具１１の形状が丸型以外の角型やその他の形状である場合には、それに応じた形状とすることができる。また、光源部４１の形状に応じて適宜変形させることも可能である。   The shape of the protection member 61 of this embodiment is an example, and is not limited to the shape of this embodiment. For example, when the shape of the luminaire 11 is a square shape other than the round shape or other shapes, the shape can be set accordingly. Further, it can be appropriately modified according to the shape of the light source unit 41.
