Description

本発明は、光の配光を制御する複数のカバーを有する照明器具に関する。 The present invention relates to a luminaire having a plurality of covers for controlling the light distribution.

従来、複数のカバーによって、光の配光を制御する照明器具が知られている。特許文献１には、ＬＥＤが実装された基板が取り付けられるフレームと、基板を覆うようにフレームに取り付けられるカバーと、カバーの内側に取り付けられ、ＬＥＤから照射された光の配光を制御する配光制御板とを備える照明装置が開示されている。カバーは、配光制御板が着脱自在に取り付けられる支持部を有し、支持部は、内側に突出したガイドレールからなる。 Conventionally, a lighting fixture that controls the light distribution by a plurality of covers has been known. In Patent Document 1, a frame to which a substrate on which an LED is mounted is attached, a cover attached to the frame so as to cover the substrate, and an arrangement attached to the inside of the cover to control the light distribution of light emitted from the LED. A lighting device including an optical control plate is disclosed. The cover has a support portion to which the light distribution control plate is detachably attached, and the support portion consists of a guide rail protruding inward.

特開２０１５－８４２９６号公報Japanese Unexamined Patent Publication No. 2015-84296

しかしながら、特許文献１に開示された照明装置は、カバーに設けられた支持部が、カバーを介して照明装置の外部に露出しているため、ＬＥＤから照射された光が支持部に当たると、カバーに影として現れる。また、支持部はリブから構成されたガイドレールであるため、安定した形状で生産し難く、他の部位と比較して厚さにばらつきが生じる。このため、ユーザが意図しない配光となるおそれがある。このように、特許文献１に開示されたような複数のカバーが用いられた照明装置において、カバーを保持する支持部に起因して所望の配光が得られない。 However, in the lighting device disclosed in Patent Document 1, since the support portion provided on the cover is exposed to the outside of the lighting device via the cover, when the light emitted from the LED hits the support portion, the cover Appears as a shadow. Further, since the support portion is a guide rail composed of ribs, it is difficult to produce the support portion in a stable shape, and the thickness varies as compared with other portions. Therefore, the light distribution may not be intended by the user. As described above, in a lighting device using a plurality of covers as disclosed in Patent Document 1, a desired light distribution cannot be obtained due to the support portion holding the covers.

本発明は、上記のような課題を解決するためになされたもので、複数のカバーを用いても所望の配光制御が可能な照明器具を提供するものである。 The present invention has been made to solve the above-mentioned problems, and provides a lighting fixture capable of desired light distribution control even when a plurality of covers are used.

本発明に係る照明器具は、内部に中空部が形成された器具本体と、器具本体に取り付けられる光源ユニットと、を備え、光源ユニットは、光を照射する発光部と、発光部が載置され、中空部に収容されるフレームと、発光部を覆うようにフレームに取り付けられ、発光部から照射された光の配光を制御する第１のカバーと、第１のカバーに取り付けられ、発光部から照射された光の配光を制御する第２のカバーと、を有し、第１のカバーは、中空部に配置され、第２のカバーを保持する保持部と、保持部から延び、器具本体の外側に突出する主カバー部と、主カバー部から外側に延び、保持部と共に第２のカバーを保持する屈曲部と、を有する。 The lighting fixture according to the present invention includes a fixture main body having a hollow portion formed therein and a light source unit attached to the fixture main body, and the light source unit includes a light emitting portion that irradiates light and a light emitting portion. , A frame housed in the hollow portion, a first cover attached to the frame so as to cover the light emitting portion and controlling the light distribution of the light emitted from the light emitting portion, and a first cover attached to the first cover and the light emitting portion. It has a second cover that controls the light distribution of the light emitted from the first cover, the first cover is arranged in a hollow portion, a holding portion that holds the second cover, and an instrument that extends from the holding portion. It has a main cover portion that protrudes to the outside of the main body, and a bent portion that extends outward from the main cover portion and holds the second cover together with the holding portion .

本発明によれば、第２のカバーを保持する保持部が、器具本体の中空部に配置されている。このため、発光部から照射された光が保持部に当たっても、保持部に当たった光は、中空部内で拡散される。よって、保持部に当たった光は、第１のカバーに直接当たらないため、第１のカバーに影が現れることを抑制することができる。このように、照明器具は、複数のカバーを用いても所望の配光制御が可能である。 According to the present invention, the holding portion for holding the second cover is arranged in the hollow portion of the instrument body. Therefore, even if the light emitted from the light emitting portion hits the holding portion, the light hitting the holding portion is diffused in the hollow portion. Therefore, since the light that hits the holding portion does not directly hit the first cover, it is possible to suppress the appearance of shadows on the first cover. As described above, the luminaire can control the desired light distribution even if a plurality of covers are used.

図６は、実施の形態１における光源ユニット２００を示す断面図であり、図２のＡ－Ａ断面図のうち、光源ユニット２００を示す。図７は、実施の形態１における光源ユニット２００を示す分解断面図である。図５、図６及び図７に示すように、発光部２１０は、光源２１２と、基板２１１とを有している。光源２１２は、光を照射するものであり、例えば複数のＬＥＤからなる。基板２１１は、光源２１２が設けられた長手方向に延びる板状の部材であり、複数の光源２１２が長手方向に一列に並べられている。フレーム２２０は、基板２１１が取り付けられる部材であり、基板２１１が載置される載置面２２１と、載置面２２１の両端から垂直に延びる立ち上がり部２２２とを有している。 FIG. 6 is a cross-sectional view showing the light source unit 200 according to the first embodiment, and shows the light source unit 200 in the cross-sectional view taken along the line AA of FIG. FIG. 7 is an exploded cross-sectional view showing the light source unit 200 according to the first embodiment. As shown in FIGS. 5, 6 and 7, the light emitting unit 210 has a light source 212 and a substrate 211. The light source 212 irradiates light, and is composed of, for example, a plurality of LEDs. The substrate 211 is a plate-shaped member provided with a light source 212 and extending in the longitudinal direction, and a plurality of light sources 212 are arranged in a row in the longitudinal direction. The frame 220 is a member on which the substrate 211 is mounted, and has a mounting surface 221 on which the substrate 211 is mounted, and rising portions 222 extending vertically from both ends of the mounting surface 221.

第１のカバー２３０は、発光部２１０から照射された光の配光を制御し、光源２１２及び基板２１１を覆うようにフレーム２２０に取り付けられる長手方向に延在する部材である。第１のカバー２３０は、例えば樹脂材料からなる。第１のカバー２３０は、フレーム２２０と係合する一対の係合部２３１と、一対の係合部２３１の先端から内側に延びる一対の保持部２３２ａとを有している。また、第１のカバー２３０は、一対の係合部２３１の先端から延びる主カバー部２３３と、主カバー部２３３の途中から外側に延びる一対の化粧部２３４とを有している。一対の係合部２３１の内部には、フレーム２２０が挿入され、係合部２３１とフレーム２２０とが係合することによって、フレーム２２０と第１のカバー２３０とが固定される。 The first cover 230 is a member that controls the light distribution of the light emitted from the light emitting unit 210 and is attached to the frame 220 so as to cover the light source 212 and the substrate 211 and extends in the longitudinal direction. The first cover 230 is made of, for example, a resin material. The first cover 230 has a pair of engaging portions 231 that engage with the frame 220, and a pair of holding portions 232a that extend inward from the tips of the pair of engaging portions 231. Further, the first cover 230 has a main cover portion 233 extending from the tips of the pair of engaging portions 231 and a pair of decorative portions 234 extending outward from the middle of the main cover portion 233. A frame 220 is inserted inside the pair of engaging portions 231 and the frame 220 and the first cover 230 are fixed by engaging the engaging portions 231 and the frame 220.

一対の保持部２３２ａは、主カバー部２３３との間に溝部２３２を形成しており、溝部２３２に第２のカバー２４０が取り付けられる。ここで、保持部２３２ａの先端は、発光部２１０に向かって傾斜して延びている。光源２１２から照射された光が、保持部２３２ａに当たっても、保持部２３２ａで反射されて主カバー部２３３に向かって出射する。即ち、光源２１２から出射された光が保持部２３２ａと係合部２３１との間に入り込んで主カバー部２３３側に出射され難いため、光の損失を減らすことができ、光源ユニット２００の光効率性を高めることができる。ここで、保持部２３２ａは、中空部１１０に配置されている。 The pair of holding portions 232a form a groove portion 232 with the main cover portion 233, and the second cover 240 is attached to the groove portion 232. Here, the tip of the holding portion 232a is inclined and extends toward the light emitting portion 210. Even if the light emitted from the light source 212 hits the holding portion 232a, it is reflected by the holding portion 232a and emitted toward the main cover portion 233. That is, since the light emitted from the light source 212 enters between the holding portion 232a and the engaging portion 231 and is difficult to be emitted to the main cover portion 233 side, the light loss can be reduced and the light efficiency of the light source unit 200 can be reduced. It can enhance the sex. Here, the holding portion 232a is arranged in the hollow portion 110.

一対の主カバー部２３３は、係合部２３１の先端から一旦内側に屈曲し、その後床側に延びている。主カバー部２３３の屈曲部２３３ａと保持部２３２ａとの間に、溝部２３２が形成されている。一対の主カバー部２３３は、床側に延びた先端同士が水平方向において接続されている。主カバー部２３３を通過した光は、被照射空間に照射される。化粧部２３４は、光源ユニット２００が器具本体１００に取り付けられたときに鍔部１１３に接触して鍔部１１３を覆う。これにより、床側から照明器具１０００を視認しても、鍔部１１３は化粧部２３４に隠れて見えない。 The pair of main cover portions 233 are once bent inward from the tip of the engaging portion 231 and then extend to the floor side. A groove portion 232 is formed between the bent portion 233a and the holding portion 232a of the main cover portion 233. In the pair of main cover portions 233, the tips extending toward the floor are connected to each other in the horizontal direction. The light that has passed through the main cover portion 233 is applied to the irradiated space. The decorative portion 234 contacts the flange portion 113 when the light source unit 200 is attached to the instrument main body 100 and covers the flange portion 113. As a result, even if the lighting fixture 1000 is visually recognized from the floor side, the flange portion 113 is hidden behind the decorative portion 234 and cannot be seen.

第２のカバー２４０は、発光部２１０から照射された光の配光を制御し、長手方向に延びる板状の拡散部材である。第２のカバー２４０は、溝部２３２に差し込まれ、光源２１２と対向する位置に設置されている。第２のカバー２４０は、光源２１２から照射された光を拡散させることによって、第１のカバー２３０に光ムラが生じることを抑制している。第２のカバー２４０は、特に、長手方向に生じる光ムラを抑制している。 The second cover 240 is a plate-shaped diffusion member that controls the light distribution of the light emitted from the light emitting unit 210 and extends in the longitudinal direction. The second cover 240 is inserted into the groove portion 232 and is installed at a position facing the light source 212. The second cover 240 suppresses the occurrence of light unevenness on the first cover 230 by diffusing the light emitted from the light source 212. The second cover 240 particularly suppresses light unevenness that occurs in the longitudinal direction.

エンドカバー２５０は、第１のカバー２３０の断面形状と同様の形状をなしており、第１のカバー２３０の長手方向の両端の開口１１０ａを塞ぐ。エンドカバー２５０が第１のカバー２３０に取り付けられることによって、第１のカバー２３０の溝部２３２に第２のカバー２４０が取り付けられた状態を保持し、第２のカバー２４０が長手方向に変位することが抑制される。エンドカバー２５０は、第１のカバー２３０と同様の樹脂材料からなり、接着剤等によって第１のカバー２３０の長手方向の両端に取り付けられる。 The end cover 250 has a shape similar to the cross-sectional shape of the first cover 230, and closes the openings 110a at both ends of the first cover 230 in the longitudinal direction. By attaching the end cover 250 to the first cover 230, the state in which the second cover 240 is attached to the groove 232 of the first cover 230 is maintained, and the second cover 240 is displaced in the longitudinal direction. Is suppressed. The end cover 250 is made of the same resin material as the first cover 230, and is attached to both ends of the first cover 230 in the longitudinal direction by an adhesive or the like.

なお、エンドカバー２５０は、第１のカバー２３０と係合する着脱自在の係合機構によって取り付けられてもよい。これにより、第２のカバー２４０を交換することが容易となり、配光性能が異なる複数の第２のカバー２４０を利用することができる。従って、光源ユニット２００の配光特性を容易に変更することができる。また、エンドカバー２５０の材質として、乳白又は不透過の白色材料を用いることによって、エンドカバー２５０側から出射する光の量を調整することができる。 The end cover 250 may be attached by a detachable engaging mechanism that engages with the first cover 230. This makes it easy to replace the second cover 240, and a plurality of second covers 240 having different light distribution performance can be used. Therefore, the light distribution characteristics of the light source unit 200 can be easily changed. Further, by using a milky white or opaque white material as the material of the end cover 250, the amount of light emitted from the end cover 250 side can be adjusted.

図８は、実施の形態１に係る照明器具１０００を示す組立断面図であり、図２のＡ－Ａ断面図である。図８に示すように、器具本体１００に光源ユニット２００が取り付けられて照明器具１０００が組み立てられる。光源ユニット２００において、器具本体１００の開口１１０ａに対し、主カバー部２３３が外側に位置し、溝部２３２及び係合部２３１が内側である中空部１１０に位置している。即ち、保持部２３２ａが、中空部１１０の開口１１０ａから、中空部１１０の内側に距離Ｌだけ離れた位置に配置されている。 FIG. 8 is an assembly cross-sectional view showing the lighting fixture 1000 according to the first embodiment, and is a cross-sectional view taken along the line AA of FIG. As shown in FIG. 8, the light source unit 200 is attached to the fixture body 100 to assemble the lighting fixture 1000. In the light source unit 200, the main cover portion 233 is located outside the opening 110a of the instrument main body 100, and the groove portion 232 and the engaging portion 231 are located in the hollow portion 110 inside. That is, the holding portion 232a is arranged at a position separated from the opening 110a of the hollow portion 110 inside the hollow portion 110 by a distance L.

本実施の形態１によれば、第２のカバー２４０を保持する保持部２３２ａが、器具本体１００の中空部１１０に配置されている。このため、発光部２１０から照射された光が保持部２３２ａに当たっても、保持部２３２ａに当たった光は、中空部１１０内で拡散される。ここで、器具本体１００の開口１１０ａから被照射空間に露出している部分は、第１のカバー２３０のみである。 According to the first embodiment, the holding portion 232a for holding the second cover 240 is arranged in the hollow portion 110 of the instrument main body 100. Therefore, even if the light emitted from the light emitting unit 210 hits the holding portion 232a, the light hitting the holding portion 232a is diffused in the hollow portion 110. Here, the portion exposed to the irradiated space from the opening 110a of the instrument main body 100 is only the first cover 230.

よって、保持部２３２ａに当たった光は、第１のカバー２３０に直接当たらないため、第１のカバー２３０に影が現れることを抑制することができる。このように、照明器具１０００は、複数のカバーを用いても所望の配光制御が可能である。また、溝部２３２が中空部１１０内に存在するため、光が保持部２３２ａに当たっても、第１のカバー２３０の配光制御に影響を与えることを抑制することができる。 Therefore, since the light that hits the holding portion 232a does not directly hit the first cover 230, it is possible to suppress the appearance of shadows on the first cover 230. As described above, the luminaire 1000 can control the desired light distribution even if a plurality of covers are used. Further, since the groove portion 232 exists in the hollow portion 110, it is possible to suppress the influence of the light distribution control of the first cover 230 even if the light hits the holding portion 232a.

保持部２３２ａは、発光部２１０に向かって傾斜して延びている。このため、光源２１２から照射された光が、保持部２３２ａに当たっても、保持部２３２ａで反射されて主カバー部２３３に向かって出射する。即ち、光源２１２から出射された光が保持部２３２ａと係合部２３１との間に入り込んで主カバー部２３３側に出射され難いため、光の損失を減らすことができる。従って、光源ユニット２００の光効率性を高めることができる。 The holding portion 232a is inclined and extends toward the light emitting portion 210. Therefore, even if the light emitted from the light source 212 hits the holding portion 232a, it is reflected by the holding portion 232a and emitted toward the main cover portion 233. That is, since the light emitted from the light source 212 does not easily enter between the holding portion 232a and the engaging portion 231 and is emitted to the main cover portion 233 side, the loss of light can be reduced. Therefore, the light efficiency of the light source unit 200 can be improved.

また、化粧部２３４は、器具本体１００の中空部１１０と光源ユニット２００との間の隙間を覆っている。このため、床側から照明器具１０００を視認しても、隙間は化粧部２３４に隠れて見えない。従って、隙間に起因する意匠性の低下を抑制することができる。また、器具本体１００と光源ユニット２００とを連結する連結機構としてバネが用いられる場合、化粧部２３４と鍔部１１３との接触位置を考慮することによって、光源ユニット２００が組み立てられるときに容易に位置決めすることができる。 Further, the decorative portion 234 covers the gap between the hollow portion 110 of the instrument main body 100 and the light source unit 200. Therefore, even if the lighting fixture 1000 is visually recognized from the floor side, the gap is hidden behind the decorative portion 234 and cannot be seen. Therefore, it is possible to suppress the deterioration of the design due to the gap. Further, when a spring is used as a connecting mechanism for connecting the instrument main body 100 and the light source unit 200, the contact position between the decorative portion 234 and the flange portion 113 is taken into consideration so that the light source unit 200 can be easily positioned when assembled. can do.

なお、本実施の形態では、器具本体１００が、一面が開口した直方体形状である場合について例示しているが、長手側方に反射部が設けられた器具本体としてもよい。例えば、器具本体は、逆富士型形状のものでもよい。また、器具本体１００の天井への固定方法は、固定穴１１１ａに固定具を挿通して取り付ける方法以外にも、蓋部１１４に取付金具（爪状）を取り付けシステム天井のＴバーに固定する方法をとってもよい。 In the present embodiment, the case where the instrument main body 100 has a rectangular parallelepiped shape with one side open is illustrated, but the instrument main body may be provided with a reflective portion on the longitudinal side. For example, the instrument body may have an inverted Fuji shape. Further, as a method of fixing the instrument body 100 to the ceiling, in addition to the method of inserting the fixing tool into the fixing hole 111a and attaching the fixture, a method of attaching a mounting bracket (claw shape) to the lid 114 and fixing it to the T-bar of the system ceiling. You may take.
