Description

本発明は、虫や埃等の侵入に対応できる照明器具に関するものである。   The present invention relates to a lighting apparatus that can cope with intrusion of insects, dust, and the like.

従来、侵入した昆虫等の虫を捕虫する照明器具が知られている（例えば、特許文献１参照）。
図５（Ａ）および図５（Ｂ）に示すように、特許文献１に記載の照明器具（シーリングライト）１００では、器具本体１０１と、光源である蛍光灯１０２と、透光部材であるグローブ１０３ を有しており、器具本体１０１の上面部分が天井に取付けられる。
グローブ１０３の上面には、３カ所に捕虫部品１０４が設けられている。捕虫部品１０４は、昆虫等の害虫を誘引して捕獲するものであり、グローブ１０３の上面側の３箇所に設けられた差込穴（図示省略）に差込まれて、グローブ１０３に取付けられている。この捕虫部品１０４は、透光性を有しており、蛍光灯１０２からの光を透過するようになっている。 Conventionally, lighting fixtures that catch insects such as invading insects are known (see, for example, Patent Document 1).
As shown in FIGS. 5A and 5B, in a lighting fixture (ceiling light) 100 described in Patent Document 1, a fixture body 101, a fluorescent lamp 102 as a light source, and a globe as a translucent member. 103, and the upper surface portion of the instrument body 101 is attached to the ceiling.
On the upper surface of the globe 103, insect trapping parts 104 are provided at three locations. The insect catching part 104 attracts and captures insects and other harmful insects, and is inserted into three insertion holes (not shown) provided on the upper surface side of the globe 103 and attached to the globe 103. Yes. The insect trap 104 has translucency and transmits light from the fluorescent lamp 102.

捕虫部品１０４は、昆虫が侵入する開口部１０５を有しており、開口部１０５と反対側の末端部（底部）が封鎖された略円筒形状の袋状の構造をしている。一般に、昆虫は光に誘引される習性を持っているので、捕虫部品１０４は、グローブ１０３を透過する光よりも誘虫性の高い光を透過するようになっており、照明器具１００の近傍に飛来する昆虫を引き寄せるようになっている。
また、捕虫部品１０４内部の途中部分には、侵入した昆虫が脱出するのを防止する退路制限具（図示省略）が配置されている。 The insect trapping part 104 has an opening 105 through which insects enter, and has a substantially cylindrical bag-like structure in which the end (bottom) opposite to the opening 105 is sealed. In general, since insects have a habit of being attracted by light, the insect catching component 104 transmits light having a higher insecticidal property than light transmitted through the globe 103, and jumps to the vicinity of the lighting apparatus 100. It is designed to attract insects.
Further, a retreat restricting tool (not shown) for preventing the invading insects from escaping is disposed in the middle part of the insect capturing part 104.

従って、照明器具１００の近傍を飛来する昆虫は、捕虫部品１０４を透過する光に誘引されて、捕虫部品１０４の開口部１０５に引き寄せられる。捕虫部品１０４によりとらえられた虫は、退路制限具により退路が制限されるので、捕虫部品１０４から脱出できない。   Therefore, insects flying in the vicinity of the lighting device 100 are attracted to the light transmitted through the insect capturing component 104 and are attracted to the opening 105 of the insect capturing component 104. Insects caught by the insect trapping part 104 are prevented from exiting from the insect trapping part 104 because the exit path is restricted by the withdrawal limiter.

（第１実施形態）
以下、本発明に係る第１実施形態の照明器具について、図面を用いて説明する。なお、以下の説明においては、天井面１１に取り付けた状態で、天井面１１側を「上」、照明側（床側）を「下」として説明する。
図１に示すように、実施形態の照明器具１０Ａは、例えば天井面１１に取り付けて、主に下方を照明するシーリングライトに適用することができる。 (First embodiment)
Hereinafter, the lighting fixture of 1st Embodiment which concerns on this invention is demonstrated using drawing. In the following description, the ceiling surface 11 side is described as “upper” and the illumination side (floor side) as “lower” in a state of being attached to the ceiling surface 11.
As shown in FIG. 1, the lighting fixture 10A of the embodiment can be applied to a ceiling light that is attached to, for example, the ceiling surface 11 and mainly illuminates the lower part.

照明器具１０Ａは、平面視の中央に筒状の器具本体２０を上下方向に有する。器具本体２０は、円筒形状や多角形筒状とすることができる。
器具本体２０の外周面２０１には、光源部３０が設けられている。光源部３０は、器具本体２０の外周面２０１に取り付けられる基板３１と、基板３１に実装されるＬＥＤ３２を有する。基板３１は器具本体２０の全周にわたって取り付けられており、複数個のＬＥＤ３２が所定間隔で全周に設けられている。 The lighting fixture 10A has a cylindrical fixture body 20 in the vertical direction in the center in plan view. The instrument main body 20 can be formed in a cylindrical shape or a polygonal cylindrical shape.
A light source unit 30 is provided on the outer peripheral surface 201 of the instrument body 20. The light source unit 30 includes a substrate 31 attached to the outer peripheral surface 201 of the instrument body 20 and an LED 32 mounted on the substrate 31. The board | substrate 31 is attached over the perimeter of the instrument main body 20, and several LED32 is provided in the perimeter at predetermined intervals.

器具本体２０には、支持部２１が設けられており、支持部２１は導光板４０を支持する。
導光板４０は、中心部に開口部４３を有する円板状の部材であり、開口部４３に面する端面４４は、光源部３０のＬＥＤ３２に対面する。開口部４３は、器具本体２０の形状に対応して円形や多角形とすることができる。あるいは、器具本体２０の形状にかかわらず円形とすることもできる。 The instrument body 20 is provided with a support portion 21, and the support portion 21 supports the light guide plate 40.
The light guide plate 40 is a disk-shaped member having an opening 43 at the center, and an end surface 44 facing the opening 43 faces the LED 32 of the light source unit 30. The opening 43 can be circular or polygonal corresponding to the shape of the instrument body 20. Alternatively, it may be circular regardless of the shape of the instrument body 20.

支持部２１は、導光板４０の下面（表面）４１に当接する円板状の第１挟持部２２と、導光板４０の上面（裏面）４２に当接する円板状の第２挟持部２３を有する。
第１挟持部２２の上面である第１当接面２２１は、導光板４０の下面４１における光源部３０側（すなわち、中心側）に当接する。また、第２挟持部２３の下面である第２当接面２３１は、導光板４０の上面４２における光源部３０側に当接する。これにより、導光板４０は支持部２１により支持される。 The support portion 21 includes a disc-shaped first sandwiching portion 22 that contacts the lower surface (front surface) 41 of the light guide plate 40 and a disc-shaped second sandwiching portion 23 that contacts the upper surface (back surface) 42 of the light guide plate 40. Have.
The first contact surface 221 that is the upper surface of the first clamping unit 22 contacts the light source unit 30 side (that is, the center side) of the lower surface 41 of the light guide plate 40. In addition, the second contact surface 231 that is the lower surface of the second clamping unit 23 contacts the light source unit 30 side of the upper surface 42 of the light guide plate 40. Thereby, the light guide plate 40 is supported by the support portion 21.

第１挟持部２２と第２挟持部２３とは平行に設けられており、導光板４０からの光を多く下方へ照射するために、第１挟持部２２の外径は第２挟持部２３の外径よりも小さく設定されている。
従って、照明器具１０Ａを下方から見ると、第１挟持部２２の外側に第２挟持部２３の外周部が突出しており、この第２挟持部２３の外周部は、導光板４０を通して下方に露呈する露呈領域Ｒ１を形成する。
導光板の上面４２と露呈領域Ｒ１との間には、露呈領域Ｒ１を覆う膜部材２４が設けられている。 The first clamping unit 22 and the second clamping unit 23 are provided in parallel, and the outer diameter of the first clamping unit 22 is that of the second clamping unit 23 in order to irradiate much light from the light guide plate 40 downward. It is set smaller than the outer diameter.
Accordingly, when the luminaire 10A is viewed from below, the outer peripheral portion of the second holding portion 23 protrudes outside the first holding portion 22, and the outer peripheral portion of the second holding portion 23 is exposed downward through the light guide plate 40. The exposed region R1 is formed.
A film member 24 that covers the exposed region R1 is provided between the upper surface 42 of the light guide plate and the exposed region R1.

図２に示すように、膜部材２４は、導光板４０の上面４２における光源部３０とは反対側、すなわち外側の端部側に塗布された不透過層２５を有する。不透過層２５は、導光板４０の上面４２に塗装や印刷（シルク印刷）を施すことにより設けることができる。不透過層２５の下面は白色系で処理されており、導光板４０から上向きに発せられて不透過層２５に照射された光は、下方へ反射される。
また、膜部材２４では、不透過層２５に粘着層２６が積層されており、不透過のシート２７が粘着層２６を介して不透過層２５に粘着されている。 As shown in FIG. 2, the film member 24 has an impermeable layer 25 applied to the upper surface 42 of the light guide plate 40 on the side opposite to the light source unit 30, that is, on the outer end side. The opaque layer 25 can be provided by painting or printing (silk printing) on the upper surface 42 of the light guide plate 40. The lower surface of the opaque layer 25 is processed in white, and the light emitted upward from the light guide plate 40 and applied to the opaque layer 25 is reflected downward.
In the membrane member 24, an adhesive layer 26 is laminated on the impermeable layer 25, and an impermeable sheet 27 is adhered to the impermeable layer 25 via the adhesive layer 26.

粘着層２６を導光板４０の上面４２に積層する際には、粘着層２６内に気泡が生じるおそれがある。このため、導光板４０の上面４２に不透過層２５を設けており、粘着層２６に発生した気泡は、不透過層２５の存在により、下方から導光板４０を通して見えないようになっている。
シート２７は、露呈領域Ｒ１に対応しており、露呈領域Ｒ１と同じ幅を有するリング形状を呈している。シート２７は、外周側端部のみが粘着層２６により不透過層２５に粘着されているが、粘着層２６および不透過層２５をシート２７の幅全域に設けることも可能である。
シート２７は不透過の部材であるため、シート２７より上側にあるものは、下方から導光板４０を通して見ることはできない。 When the adhesive layer 26 is laminated on the upper surface 42 of the light guide plate 40, there is a possibility that bubbles are generated in the adhesive layer 26. For this reason, the opaque layer 25 is provided on the upper surface 42 of the light guide plate 40, and bubbles generated in the adhesive layer 26 cannot be seen through the light guide plate 40 from below due to the presence of the opaque layer 25.
The sheet 27 corresponds to the exposed region R1 and has a ring shape having the same width as the exposed region R1. Only the outer peripheral side end of the sheet 27 is adhered to the impermeable layer 25 by the adhesive layer 26, but the adhesive layer 26 and the impermeable layer 25 may be provided over the entire width of the sheet 27.
Since the sheet 27 is an impermeable member, anything above the sheet 27 cannot be seen through the light guide plate 40 from below.

照明器具１０Ａの作用効果について説明する。
照明器具１０Ａでは、器具本体２０に収容された光源部３０が、器具本体２０の支持部２１に挟持されている導光板４０の端面４４に対面している。従って、光源部３０から発せられた光は、導光板４０の端面４４から導光板４０に入射し、導光板４０から出射する。この出射光により照明する。
導光板４０を支持する支持部２１は、導光板４０の下面４１における光源部３０側に第１当接面２２１が面当接する第１挟持部２２と、導光板４０の上面４２における光源部３０側に第２当接面２３１が面当接する第２挟持部２３とを有する。従って、第１挟持部２２と第２挟持部２３とで導光板４０を挟持することにより、導光板４０を支持する。 The effects of the lighting apparatus 10A will be described.
In the lighting fixture 10 </ b> A, the light source unit 30 accommodated in the fixture body 20 faces the end surface 44 of the light guide plate 40 sandwiched between the support portions 21 of the fixture body 20. Accordingly, light emitted from the light source unit 30 enters the light guide plate 40 from the end face 44 of the light guide plate 40 and exits from the light guide plate 40. Illumination is performed by the emitted light.
The support portion 21 that supports the light guide plate 40 includes a first sandwiching portion 22 in which the first contact surface 221 is in surface contact with the light source portion 30 side of the lower surface 41 of the light guide plate 40, and the light source portion 30 on the upper surface 42 of the light guide plate 40. The second abutting surface 231 has a second clamping portion 23 that abuts on the side. Therefore, the light guide plate 40 is supported by sandwiching the light guide plate 40 between the first sandwiching portion 22 and the second sandwiching portion 23.

第２挟持部２３の一部は、下方から導光板４０を厚み方向に沿って透過して露呈可能な露呈領域Ｒ１を形成する。
そして、導光板４０の上面４２と露呈領域Ｒ１との間に、露呈領域Ｒ１を覆う膜部材２４を設けた。
これにより、導光板４０を通して見える露呈領域Ｒ１と導光板４０の上面４２との間に侵入した虫や埃等を、膜部材２４により隠すことができるので、簡易な構造によりコスト高を招くことなく外観を改善することができる。
また、虫等が導光板４０を通して下方から見えないので、導光板４０の下面４１を支持する第１挟持部２２の大きさを設定する自由度が増し、光束の低下やデザインの制約を減少させることができる。 A part of the second clamping part 23 forms an exposed region R1 that can be exposed through the light guide plate 40 from below along the thickness direction.
A film member 24 that covers the exposed region R1 is provided between the upper surface 42 of the light guide plate 40 and the exposed region R1.
Accordingly, since the insects, dust, and the like that have entered between the exposed region R1 that can be seen through the light guide plate 40 and the upper surface 42 of the light guide plate 40 can be hidden by the film member 24, the cost is not increased due to a simple structure. Appearance can be improved.
In addition, since insects and the like cannot be seen from below through the light guide plate 40, the degree of freedom for setting the size of the first sandwiching portion 22 that supports the lower surface 41 of the light guide plate 40 is increased, and the reduction in luminous flux and design restrictions are reduced. be able to.

また、膜部材２４は、導光板４０の上面４２における光源部３０とは反対側（すなわち外側）の端部側に塗布された不透過層２５と、この不透過層２５に積層する粘着層２６と、粘着層２６を介して不透過層２５に粘着する不透過のシート２７とを有する。シート２７は、露呈領域Ｒ１に対応しており、露呈領域Ｒ１の全域を覆っている。
これにより、導光板４０を通して見える露呈領域Ｒ１と導光板４０の上面４２との間に侵入した虫や埃等を、確実に隠すことができる。 In addition, the film member 24 includes an impermeable layer 25 applied to an end side of the upper surface 42 of the light guide plate 40 opposite to the light source unit 30 (that is, an outer side), and an adhesive layer 26 laminated on the impermeable layer 25. And an impermeable sheet 27 that adheres to the impermeable layer 25 via the adhesive layer 26. The sheet 27 corresponds to the exposure region R1 and covers the entire area of the exposure region R1.
Thereby, insects, dust, and the like that have entered between the exposed region R <b> 1 that can be seen through the light guide plate 40 and the upper surface 42 of the light guide plate 40 can be reliably hidden.

なお、シート２７の貼付は、塗装・印刷に比して、光束の低下を減少することができるが、シート２７を貼付ける粘着層２６に気泡が発生することがあり、明暗ムラが生じる場合がある。
このため、導光板４０の上面４２に不透過層２５を設けて粘着層２６に発生する気泡を隠すので、外観を改善することができる。 Note that the application of the sheet 27 can reduce the decrease in luminous flux as compared with painting and printing. However, bubbles may be generated in the adhesive layer 26 to which the sheet 27 is applied, which may cause uneven brightness. is there.
For this reason, since the opaque layer 25 is provided on the upper surface 42 of the light guide plate 40 to hide the bubbles generated in the adhesive layer 26, the appearance can be improved.

The convex part 45 which covers the clearance gap between them was provided. The convex portion 45 is provided over the entire circumference on the outer side of the membrane member 24, and desirably has a height at which the upper end abuts on the second clamping portion 23 of the instrument main body 20.

凸部４５の形状は特に限定するものではないが、ここでは、第２挟持部２３の外周面２３２が、上に向かって拡径するように傾斜しているので、凸部４５の先端が外周面２３２に当接している。
凸部４５は、導光板４０と一体的に設けることができるが、導光板４０の上面４２に後から貼付けることも可能である。 The shape of the convex portion 45 is not particularly limited, but here, since the outer peripheral surface 232 of the second clamping portion 23 is inclined so as to increase in diameter upward, the tip of the convex portion 45 is the outer periphery. It is in contact with the surface 232.
The convex portion 45 can be provided integrally with the light guide plate 40, but can be attached to the upper surface 42 of the light guide plate 40 later.

照明器具１０Ｂの作用効果について説明する。
照明器具１０Ｂでは、導光板４０の上面４２に、導光板４０の上面４２と器具本体２０の支持部２１の第２当接面２３１との間の隙間を覆う凸部４５を設けた。
これにより、支持部２１と導光板４０の上面４２との間に、虫や埃等が侵入するのを防止することができ、簡易な構造によりコスト高を招くことなく外観を改善することができる。 The effect of the lighting fixture 10B is demonstrated.
In the lighting fixture 10 </ b> B, a convex portion 45 that covers a gap between the upper surface 42 of the light guide plate 40 and the second contact surface 231 of the support portion 21 of the fixture body 20 is provided on the upper surface 42 of the light guide plate 40.
Thereby, it is possible to prevent insects, dust, and the like from entering between the support portion 21 and the upper surface 42 of the light guide plate 40, and the appearance can be improved without increasing the cost due to a simple structure. .

図４に示すように、第３実施形態の照明器具１０Ｃでは、前述した第１実施形態の照明器具１０Ａおよび第２実施形態の照明器具１０Ｂとは異なり、支持部２１の第１挟持部２２と第２挟持部２３の外径が略等しい。
このため、前述した露呈領域Ｒ１が形成されない。 (Third embodiment)
Next, the lighting fixture of 3rd Embodiment is demonstrated. In addition, the same code | symbol is attached | subjected to the site | part which is common in the lighting fixture 10A of 1st Embodiment mentioned above, or the lighting fixture 10B of 2nd Embodiment, and the overlapping description is abbreviate | omitted.
As shown in FIG. 4, in the lighting fixture 10C of the third embodiment, unlike the lighting fixture 10A of the first embodiment and the lighting fixture 10B of the second embodiment described above, the first clamping portion 22 of the support portion 21 and The outer diameter of the 2nd clamping part 23 is substantially equal.
For this reason, the exposure region R1 described above is not formed.

一方、第１挟持部２２には、導光板４０からの光を下方へ照射するための光照射用透過部２２２が設けられている。光照射用透過部２２２の形状は特定するものではないが、例えば、円形の光照射用透過部２２２を複数個設けたり、扇形状の光照射用透過部２２２を複数個設けることもできる。
光照射用透過部２２２は、導光板４０からの光を透過するものであるため、導光板４０を通して第２挟持部２３が下方から見える露呈領域Ｒ２が形成される。 On the other hand, the first clamping unit 22 is provided with a light irradiation transmission unit 222 for irradiating light from the light guide plate 40 downward. Although the shape of the light irradiation transmission part 222 is not specified, for example, a plurality of circular light irradiation transmission parts 222 or a plurality of fan-shaped light irradiation transmission parts 222 may be provided.
Since the light irradiation transmission part 222 transmits the light from the light guide plate 40, an exposed region R <b> 2 is formed through which the second clamping part 23 can be seen from below.

従って、導光板４０の上面４２と第２挟持部２３との間に虫等が侵入して、露呈領域Ｒ２に虫等がとどまると下方から見えてしまう。
このため、導光板４０の上面４２で、露呈領域Ｒ２に対応する部分には、第１実施形態の照明器具１０Ａおよび第２実施形態の照明器具１０Ｂにおいて前述した膜部材２４を設けた。 Accordingly, when insects or the like enter between the upper surface 42 of the light guide plate 40 and the second sandwiching portion 23 and the insects or the like remain in the exposed region R2, they are visible from below.
For this reason, in the upper surface 42 of the light guide plate 40, the film member 24 described above in the lighting fixture 10A of the first embodiment and the lighting fixture 10B of the second embodiment is provided in a portion corresponding to the exposure region R2.

本発明の照明器具１０Ｃの作用効果について説明する。
この照明器具１０Ｃでは、第１挟持部２２に光照射用透過部２２２を設けたので、照明器具１０Ｃの中央部付近からも導光板４０からの光を下方へ照射することができ、照明効率が向上する。
また、光照射用透過部２２２により形成される露呈領域Ｒ２に対応して膜部材２４を設けたので、導光板４０の上面４２と第２挟持部２３との間に虫等が侵入して露呈領域Ｒ２に虫等がとどまっても、下方から見えない。
これにより、簡易な構造によりコスト高を招くことなく外観を改善することができるとともに、導光板４０の下面４１を支持する第１挟持部２２の大きさを設定する自由度が増し、光束の低下やデザインの制約を減少させることができる。 The effect of the lighting fixture 10C of this invention is demonstrated.
In this luminaire 10C, since the light transmissive portion 222 is provided in the first sandwiching portion 22, light from the light guide plate 40 can be radiated downward from near the center of the luminaire 10C, and the illumination efficiency is improved. improves.
In addition, since the film member 24 is provided corresponding to the exposure region R2 formed by the light irradiation transmission portion 222, insects or the like enter between the upper surface 42 of the light guide plate 40 and the second sandwiching portion 23 and are exposed. Even if insects stay in the region R2, they cannot be seen from below.
As a result, the appearance can be improved without incurring high costs due to a simple structure, and the degree of freedom for setting the size of the first sandwiching portion 22 that supports the lower surface 41 of the light guide plate 40 is increased, and the luminous flux is reduced. And design constraints can be reduced.

本発明の照明器具は、前述した各実施形態に限定されるものでなく、適宜な変形、改良等が可能である。
例えば、前述した各実施形態においては、光源部３０としてＬＥＤ３２を用いる場合について例示したが、これに限るものではない。蛍光灯等のその他の光源を用いることも可能である。 The lighting fixture of the present invention is not limited to the above-described embodiments, and appropriate modifications and improvements can be made.
For example, in each embodiment mentioned above, although illustrated about the case where LED32 was used as the light source part 30, it does not restrict to this. It is also possible to use other light sources such as fluorescent lamps.
