Description

本発明は、ＬＥＤを光源として例えば店舗や施設のベースライトに適用される照明器具に関する。   The present invention relates to a luminaire that is applied to, for example, a base light of a store or a facility using an LED as a light source.

従来より複数のＬＥＤ光源および反射板をケースに収容した照明器具が知られている（例えば、特許文献１参照）。   2. Description of the Related Art Conventionally, a lighting fixture in which a plurality of LED light sources and a reflecting plate are housed in a case is known (see, for example, Patent Document 1).

特開２００８−２７０１４４号公報（図２、段落番号００２８）JP 2008-270144 A (FIG. 2, paragraph number 0028)

前述した特許文献１に記載された照明器具は、反射板が複数のＬＥＤ光源をそれぞれ取り囲んで配置されているために、複数のＬＥＤ光源からの光を床面に向けて照射することができる。

The plurality of reflecting plates 102 have the same opening dimension L60 of the lower opening 103, whereby the light shielding angle α11 is set constant.
However, in such a conventional lighting fixture 100, the glare is reduced by taking a light blocking angle α11, but the light quantity to the side is reduced due to the light distribution characteristics of the LED light source 101 which is a point light source. The degree of uniformity decreases.

以下、本発明の複数の実施形態に係る照明器具について図面を参照して説明する。
（第１実施形態）
本発明の第１実施形態である照明器具１０は、複数のＬＥＤ光源１２を実装したＬＥＤ基板１３が保持部材１４に保持されたＬＥＤユニット１１と、複数の反射板形成部材１６と複数のパネル１７とが組付けられて枠部材（器具本体）１８に配列された反射板ユニット１５と、点灯装置１９とを備えて店舗や施設のベースライトに適用される。 Hereinafter, the lighting fixture which concerns on several embodiment of this invention is demonstrated with reference to drawings.
(First embodiment)
The lighting fixture 10 which is 1st Embodiment of this invention is the LED unit 11 with which the LED board 13 which mounted the some LED light source 12 was hold | maintained at the holding member 14, the some reflecting plate formation member 16, and the some panel 17 And a reflector unit 15 arranged in a frame member (equipment main body) 18 and a lighting device 19 and applied to a base light of a store or a facility.

図１、図２、図３に示すように、ＬＥＤユニット１１は、ＬＥＤ基板１３の下面に複数のＬＥＤ光源１２が実装されており、ＬＥＤ基板１３の上側に保持部材１４が組付けられている。保持部材１４は例えば金属製であり、上部に点灯装置１９が取り付けられている。点灯装置１９には、不図示のＡＣ／ＤＣコンバータやインバータ回路が内蔵されており、駆動により商用電源を直流電源に変換してＬＥＤ基板１３に有するプリント回路に供給してＬＥＤ光源１２を発光させる。
枠部材１８は、端部が垂直断面視コ字形状を有する金属製であって、コ字形状部分の内側にフランジ２０を有し、このフランジ２０を介してパネル１７の外縁部と保持部材１４の外縁部とが枠部材１８に取り付けられる。 As shown in FIGS. 1, 2, and 3, the LED unit 11 has a plurality of LED light sources 12 mounted on the lower surface of the LED substrate 13, and a holding member 14 assembled on the upper side of the LED substrate 13. . The holding member 14 is made of, for example, metal, and a lighting device 19 is attached to the upper part. The lighting device 19 incorporates an AC / DC converter (not shown) and an inverter circuit, and converts the commercial power source into a DC power source by driving and supplies it to the printed circuit on the LED board 13 to cause the LED light source 12 to emit light. .
The frame member 18 is made of metal having an U-shaped end portion in a vertical sectional view, and has a flange 20 inside the U-shaped portion, and the outer edge portion of the panel 17 and the holding member 14 via the flange 20. Are attached to the frame member 18.

図４、図５に示すように、ＬＥＤユニット１１において、保持部材１４は、板形状をなす保持部材本体部２１を有する。保持部材本体部２１は、ＬＥＤ基板１３の外周部に複数のネジ孔２２を有し、これらネジ孔２２を介してネジ（図１０参照）２３が反射板ユニット１５の反射板形成部材１６にネジ込まれることによりＬＥＤユニット１１が反射板ユニット１５に取り付けられる。さらに、保持部材１４は、ＬＥＤ基板１３の外周部においてネジ孔２２とは独立した位置に複数の突起部２４が下方に向けて突出されている。ＬＥＤ光源１２は、ＬＥＤ基板１３の長手方向および長手方向に直交する幅方向に予め定められたピッチで整列されている。   As shown in FIGS. 4 and 5, in the LED unit 11, the holding member 14 has a holding member main body portion 21 having a plate shape. The holding member main body 21 has a plurality of screw holes 22 on the outer peripheral portion of the LED substrate 13, and screws (see FIG. 10) 23 are screwed into the reflection plate forming member 16 of the reflection plate unit 15 through these screw holes 22. The LED unit 11 is attached to the reflector unit 15 by being inserted. Further, the holding member 14 has a plurality of projecting portions 24 projecting downward at a position independent of the screw hole 22 on the outer peripheral portion of the LED substrate 13. The LED light sources 12 are aligned at a predetermined pitch in the longitudinal direction of the LED substrate 13 and the width direction orthogonal to the longitudinal direction.

図６、図７、図８に示すように、反射板ユニット１５は、反射板形成部材１６のそれぞれの下面に、例えば透明や乳白色のパネル１７が組付けられており、これら反射板形成部材１６とパネル１７との組体２５が枠部材１８の内側に長手方向に沿って組付けられる。
反射板形成部材１６は、ＬＥＤユニット１１におけるＬＥＤ光源１２の数と同数の複数の連結された反射板（遮光部材）２６を有する。反射板２６は、第１実施形態においては、白色の樹脂成型材料を基材として略四角錐形状に形成されており、内面に反射面（傾斜面）２７を有するとともに外面（裏面）に突起部当接面２８を有し、上端部の頂部に予め定められた大きさの四角形の上方開口部２９を有する。 As shown in FIGS. 6, 7, and 8, the reflecting plate unit 15 includes, for example, a transparent or milky white panel 17 attached to the lower surface of each reflecting plate forming member 16. And the panel 17 are assembled along the longitudinal direction inside the frame member 18.
The reflection plate forming member 16 has a plurality of connected reflection plates (light shielding members) 26 in the same number as the LED light sources 12 in the LED unit 11. In the first embodiment, the reflecting plate 26 is formed in a substantially quadrangular pyramid shape using a white resin molding material as a base material, and has a reflecting surface (inclined surface) 27 on the inner surface and a protrusion on the outer surface (back surface). It has a contact surface 28 and has a rectangular upper opening 29 having a predetermined size at the top of the upper end.

図９、図１０、図１１、図１２に示すように、反射板形成部材１６は、樹脂製であって、保持部材本体部２１のネジ孔２２に対応した位置に複数のボス３０を有し、これらボス３０にボス孔３１を有する。そのため、保持部材本体部２１に挿通されたネジ２３がボス３０のボス孔３１にネジ込まれる。   As shown in FIGS. 9, 10, 11, and 12, the reflection plate forming member 16 is made of resin and has a plurality of bosses 30 at positions corresponding to the screw holes 22 of the holding member main body 21. These bosses 30 have boss holes 31. Therefore, the screw 23 inserted through the holding member main body 21 is screwed into the boss hole 31 of the boss 30.

図１３に示すように、保持部材１４の突起部２４は、保持部材本体部２１におけるＬＥＤ基板１３の外周部の所定位置を下方に向けて切り曲げ加工することにより形成される。そして、突起部２４は、その先端部に反射板２６の突起部当接面２８の傾斜形状に平行な角度に形成された反射板支持部（反射板当接部）３２を有する。なお、突起部２４は、保持部材本体部２１の所定位置を下方に向けて切り曲げ加工することにより板形状に形成するのに代えて、円筒形等に形成されても良い。もちろん、その場合も、先端部が反射板２６の突起部当接面２８の傾斜形状に平行な角度に形成される。また、突起部２４は、保持部材１４に代えて、反射板２６側に形成しても良く、その場合は、反射板２６の保持部材１４側が反射板２６の裏面の傾斜形状に平行な角度に形成される。   As shown in FIG. 13, the protrusion 24 of the holding member 14 is formed by cutting and bending a predetermined position of the outer peripheral portion of the LED substrate 13 in the holding member main body 21 downward. The protrusion 24 has a reflection plate support portion (reflection plate contact portion) 32 formed at an angle parallel to the inclined shape of the protrusion contact surface 28 of the reflection plate 26 at the tip. Note that the protrusion 24 may be formed in a cylindrical shape or the like instead of being formed into a plate shape by cutting and bending a predetermined position of the holding member main body portion 21 downward. Of course, also in that case, the tip portion is formed at an angle parallel to the inclined shape of the protruding portion abutting surface 28 of the reflecting plate 26. Further, the protrusion 24 may be formed on the reflecting plate 26 side instead of the holding member 14. In this case, the holding member 14 side of the reflecting plate 26 is at an angle parallel to the inclined shape of the back surface of the reflecting plate 26. It is formed.

図１４、図１５に示すように、ＬＥＤユニット１１を反射板ユニット１５の反射板形成部材１６に組付けるにあたり、保持部材１４が枠部材１８のフランジ２０上に載置されてから、保持部材本体部２１に挿通されたネジ２３がボス３０のボス孔３１にネジ込まれる。このとき、保持部材１４に有する突起部２４の反射板支持部３２が反射板２６の裏面の突起部当接面２８に最初に当接することにより反射板２６をＬＥＤ光源１２に合致する所定位置に誘導する。   As shown in FIGS. 14 and 15, in assembling the LED unit 11 to the reflection plate forming member 16 of the reflection plate unit 15, after the holding member 14 is placed on the flange 20 of the frame member 18, the holding member main body is mounted. The screw 23 inserted through the portion 21 is screwed into the boss hole 31 of the boss 30. At this time, the reflecting plate support portion 32 of the protrusion 24 provided on the holding member 14 first comes into contact with the protrusion contact surface 28 on the back surface of the reflecting plate 26, thereby bringing the reflecting plate 26 into a predetermined position that matches the LED light source 12. Induce.

図１６、図１７に示すように、保持部材１４の保持部材本体部２１に挿通されたネジ２３がボス３０のボス孔３１にネジ込まれることにより、ＬＥＤユニット１１のＬＥＤ光源１２に対して反射板形成部材１６の個々の反射板２６における上方開口部２９が位置合わせされて固定される。これにより、従来のものと比べて、反射板２６の上方開口部２９の開口寸法Ｌ１を小さく設定できるとともに反射面２７の傾斜角度α１を小さくできる。従って、ＬＥＤ光源１２からの光のうちの反射板２６の反射面２７で反射した反射光を効率良く下方へ向けることができる。特に、反射板２６の反射面２７で反射した反射光のパネル１７に対する入射角が垂直に近づくために、パネル１７の内面で反射してしまう光を低減することができる。   As shown in FIGS. 16 and 17, the screw 23 inserted through the holding member main body 21 of the holding member 14 is screwed into the boss hole 31 of the boss 30, thereby reflecting the LED light source 12 of the LED unit 11. The upper openings 29 in the individual reflecting plates 26 of the plate forming member 16 are aligned and fixed. Thereby, compared with the conventional one, the opening dimension L1 of the upper opening 29 of the reflecting plate 26 can be set smaller, and the inclination angle α1 of the reflecting surface 27 can be made smaller. Therefore, the reflected light reflected by the reflecting surface 27 of the reflecting plate 26 out of the light from the LED light source 12 can be efficiently directed downward. In particular, since the incident angle of the reflected light reflected by the reflecting surface 27 of the reflecting plate 26 with respect to the panel 17 approaches a vertical direction, the light reflected by the inner surface of the panel 17 can be reduced.

図１８に示すように、保持部材１４の保持部材本体部２１に挿通されたネジ２３がボス３０のボス孔３１にネジ込まれた際、ＬＥＤ基板１３と反射板２６の上端面との間隔寸法Ｌ２よりも、保持部材１４の突起部２４の反射板支持部３２と反射板２６の裏面の突起部当接面２８との間の間隔寸法Ｌ３の方が小さくなっている。これにより、ネジ２３のネジ込み時等に反射板２６を上方に押圧する荷重が反射板２６にかかったとしても、突起部２４を介して、その荷重を保持部材１４が受けることになるために、ＬＥＤ基板１３およびＬＥＤ光源１２に反射板２６が接触しない。   As shown in FIG. 18, when the screw 23 inserted through the holding member main body 21 of the holding member 14 is screwed into the boss hole 31 of the boss 30, the distance between the LED substrate 13 and the upper end surface of the reflecting plate 26. The distance L3 between the reflection plate support portion 32 of the protrusion 24 of the holding member 14 and the protrusion contact surface 28 on the back surface of the reflection plate 26 is smaller than L2. As a result, even if a load that presses the reflection plate 26 upward is applied to the reflection plate 26 when the screw 23 is screwed in or the like, the holding member 14 receives the load via the protrusion 24. The reflector 26 does not contact the LED substrate 13 and the LED light source 12.

図１９、図２０に示すように、照明器具１０の第１変形例では、保持部材１４の保持部材本体部２１におけるＬＥＤ基板１３の外周部に複数のボス孔３３が形成されている。そして、反射板形成部材１６に、保持部材本体部２１のボス孔３３に対応した位置に複数のボス３４を有する。
この場合、保持部材１４を反射板形成部材１６に取り付けるにあたり、保持部材１４のボス孔３３を反射板形成部材１６のボス３４に外挿させてから、反射板形成部材１６から飛び出しているボス３４が熱溶着等により保持部材１４に固定される。 As shown in FIGS. 19 and 20, in the first modification of the lighting fixture 10, a plurality of boss holes 33 are formed in the outer peripheral portion of the LED substrate 13 in the holding member main body portion 21 of the holding member 14. The reflecting plate forming member 16 has a plurality of bosses 34 at positions corresponding to the boss holes 33 of the holding member main body 21.
In this case, when attaching the holding member 14 to the reflecting plate forming member 16, the boss 34 protruding from the reflecting plate forming member 16 after the boss hole 33 of the holding member 14 is extrapolated to the boss 34 of the reflecting plate forming member 16. Is fixed to the holding member 14 by heat welding or the like.

図２１、図２２に示すように、照明器具１０の第２変形例では、保持部材１４の保持部材本体部２１におけるＬＥＤ基板１３の外周部に複数のＵ字切欠３５が形成されている。そして、反射板形成部材１６に、保持部材本体部２１のＵ字切欠３５に対応した位置に複数のボス３６を有する。
この場合、保持部材１４を反射板形成部材１６に取り付けるにあたり、保持部材１４のＵ字切欠３５を反射板形成部材１６のボス３６に外挿させてから、反射板形成部材１６から飛び出しているボス３６が熱溶着等により保持部材１４に固定される。 As shown in FIGS. 21 and 22, in the second modification of the lighting apparatus 10, a plurality of U-shaped notches 35 are formed on the outer peripheral portion of the LED substrate 13 in the holding member main body portion 21 of the holding member 14. The reflecting plate forming member 16 has a plurality of bosses 36 at positions corresponding to the U-shaped notches 35 of the holding member main body 21.
In this case, when attaching the holding member 14 to the reflecting plate forming member 16, the U-shaped notch 35 of the holding member 14 is extrapolated to the boss 36 of the reflecting plate forming member 16 and then the boss protruding from the reflecting plate forming member 16. 36 is fixed to the holding member 14 by heat welding or the like.

従って、この第１実施形態の照明器具１０においては、保持部材１４に有する突起部２４の反射板支持部３２により反射板２６の裏面の突起部当接面２８が誘導される。そのため、この第１実施形態の照明器具１０においては、ＬＥＤユニット１１のＬＥＤ光源１２に対して反射板形成部材１６の個々の反射板２６における上方開口部２９が位置合わせされる。
これにより、この第１実施形態の照明器具１０においては、従来のものと比べて、反射板１６の上方開口部２９の開口寸法Ｌ１を小さく設定できるとともに、反射面２７の傾斜角度α１を小さくできる。そのため、この第１実施形態の照明器具１０においては、ＬＥＤ光源１２からの光のうちの反射板２６の反射面２７で反射した反射光を効率良く下方へ向けることができるので、ＬＥＤ光源１２の光を下方へ効率的に反射することにより器具効率を高められる。 Therefore, in the lighting fixture 10 of the first embodiment, the projection contact surface 28 on the back surface of the reflection plate 26 is guided by the reflection plate support portion 32 of the projection 24 provided on the holding member 14. Therefore, in the lighting fixture 10 of the first embodiment, the upper openings 29 in the individual reflecting plates 26 of the reflecting plate forming member 16 are aligned with the LED light sources 12 of the LED unit 11.
Thereby, in the lighting fixture 10 of this 1st Embodiment, while being able to set the opening dimension L1 of the upper opening part 29 of the reflecting plate 16 small compared with the conventional thing, the inclination | tilt angle (alpha) 1 of the reflective surface 27 can be made small. . Therefore, in the lighting fixture 10 of the first embodiment, the reflected light reflected by the reflecting surface 27 of the reflecting plate 26 out of the light from the LED light source 12 can be efficiently directed downward. By efficiently reflecting light downward, the instrument efficiency can be increased.

また、この第１実施形態の照明器具１０においては、ＬＥＤ基板１３と反射板２６の上端面との間隔寸法Ｌ２よりも、保持部材１４の突起部２４の反射板支持部３２と反射板２６の裏面の突起部当接面２８との間の間隔寸法Ｌ３の方が小さくなっている。
これにより、この第１実施形態の照明器具１０においては、ネジ２３のネジ込み時等に反射板２６を上方に押圧する荷重が反射板２６にかかった場合、突起部２４を介して、その荷重を保持部材１４が受けることになるために、ＬＥＤ基板１３およびＬＥＤ光源１２に反射板２６が接触することがなく、ＬＥＤ光源１２およびＬＥＤ基板１３への損傷を防止できる。 Moreover, in the lighting fixture 10 of this 1st Embodiment, rather than the space | interval dimension L2 of the LED board 13 and the upper end surface of the reflecting plate 26, the reflecting plate support part 32 of the projection part 24 of the holding member 14, and the reflecting plate 26 of FIG. The distance L3 between the rear surface protruding portion contact surface 28 is smaller.
Thereby, in the lighting fixture 10 of this 1st Embodiment, when the load which presses the reflection board 26 upwards at the time of screwing in of the screw 23, etc. is applied to the reflection board 26, the load is provided via the projection part 24. Therefore, the reflecting plate 26 does not come into contact with the LED substrate 13 and the LED light source 12, and damage to the LED light source 12 and the LED substrate 13 can be prevented.

そして、この第１実施形態の照明器具１０においては、保持部材１４の保持部材本体部２１に挿通されたネジ２３がボス３０のボス孔３１にネジ込まれる際、保持部材１４に有する突起部２４の反射板支持部３２により反射板２６の裏面の突起部当接面２８が誘導される。
これにより、この第１実施形態の照明器具１０においては、ＬＥＤユニット１１のＬＥＤ光源１２に対して反射板形成部材１６の個々の反射板２６における上方開口部２９を確実に位置合わせできる。 And in the lighting fixture 10 of this 1st Embodiment, when the screw | thread 23 penetrated by the holding member main-body part 21 of the holding member 14 is screwed in the boss hole 31 of the boss | hub 30, the projection part 24 which the holding member 14 has. The projecting portion abutting surface 28 on the rear surface of the reflecting plate 26 is guided by the reflecting plate support portion 32.
Thereby, in the lighting fixture 10 of this 1st Embodiment, the upper opening part 29 in each reflecting plate 26 of the reflecting plate formation member 16 can be reliably aligned with respect to the LED light source 12 of the LED unit 11.

（第２実施形態）
次に、本発明の第２実施形態の照明器具について説明する。なお、以下の各実施形態において、上述した第１実施形態と重複する構成要素や機能的に同様な構成要素については、図中に同一符号あるいは相当符号を付することによって説明を簡略化あるいは省略する。 (Second Embodiment)
Next, the lighting fixture of 2nd Embodiment of this invention is demonstrated. In the following embodiments, components that are the same as those in the first embodiment described above or functionally similar components are simplified or omitted by giving the same reference numerals or equivalent symbols in the drawings. To do.

図２３に示すように、本発明の第２実施形態の照明器具４０は、反射板形成部材１６における長手方向に直交する幅方向の外側に位置する反射板４１と、反射板４１の内側に位置する反射板４２と、反射板４２の内側に位置する反射板４３とにおいて、上下方向の寸法は同一とし、幅方向の寸法を外側のみ変更したものである。   As shown in FIG. 23, the lighting fixture 40 according to the second embodiment of the present invention includes a reflecting plate 41 positioned outside in the width direction orthogonal to the longitudinal direction of the reflecting plate forming member 16, and positioned inside the reflecting plate 41. In the reflecting plate 42 and the reflecting plate 43 positioned inside the reflecting plate 42, the vertical dimension is the same, and the width dimension is changed only on the outer side.

すなわち、照明器具４０は、反射板形成部材１６における長手方向に直交する幅方向の外側に位置する反射板４１の下方開口部４４の開口寸法Ｌ４が、反射板４１の内側に位置する反射板４２の下方開口部４５の開口寸法Ｌ５よりも大きく設定されている。そして、反射板４２の内側に位置する反射板４３の開口寸法Ｌ５が反射板４２と同一に設定されている。そのため、ＬＥＤユニット１１は、外側に位置するＬＥＤ光源１２が、外側に位置する反射板４１の下方開口部４４の開口中心に対して内側にオフセットされて配置されている。   That is, in the luminaire 40, the reflecting plate 42 in which the opening dimension L4 of the lower opening 44 of the reflecting plate 41 located outside the width direction orthogonal to the longitudinal direction of the reflecting plate forming member 16 is located inside the reflecting plate 41. Is set to be larger than the opening dimension L5 of the lower opening 45. The opening dimension L5 of the reflecting plate 43 located inside the reflecting plate 42 is set to be the same as that of the reflecting plate 42. Therefore, the LED unit 11 is arranged such that the LED light source 12 positioned outside is offset inward with respect to the opening center of the lower opening 44 of the reflecting plate 41 positioned outside.

照明器具４０では、内側に位置する反射板４２、４３の反射面４６が有する傾斜角度α２よりも、外側に位置する反射板４１の反射面４７が有する傾斜角度α３の方が小さく（浅く）なっている。そのため、内側に位置する反射板４２、４３の反射面４６が有する遮光角α４よりも、外側に位置する反射板４１の反射面４７が有する遮光角α５の方が小さくなっている。   In the lighting fixture 40, the inclination angle α3 of the reflection surface 47 of the reflection plate 41 located outside is smaller (shallow) than the inclination angle α2 of the reflection surface 46 of the reflection plates 42 and 43 located inside. ing. Therefore, the light shielding angle α5 of the reflecting surface 47 of the reflecting plate 41 located on the outer side is smaller than the light shielding angle α4 of the reflecting surface 46 of the reflecting plates 42 and 43 located on the inner side.

これにより、外側に位置するＬＥＤ光源１２からの光が、より側方に向けて照射される。これに対して、内側に位置するＬＥＤ光源１２からの光は、より側方へ向けて照射されない。加えて、外側に位置するＬＥＤ光源１２からの光は、内側に位置するＬＥＤ光源１２からの光の遮光特性および反射特性に影響を与えないために、オフセットされることに伴う光学性能の変動を内側方向に影響させることがない。なお、反射板４１、４２、４３は、金属製であっても良く、それらの表面が銀色等の、より反射率の高いものや、黒色等の反射率の低いものであっても良い。さらに、略四角錐形状に代えて、円錐形状に形成されても良い。   Thereby, the light from the LED light source 12 located outside is irradiated toward the side. On the other hand, the light from the LED light source 12 located on the inner side is not irradiated toward the side. In addition, since the light from the LED light source 12 located on the outside does not affect the light shielding characteristics and the reflection characteristics of the light from the LED light source 12 located on the inside, fluctuations in optical performance due to offset are caused. Does not affect the inward direction. In addition, the reflecting plates 41, 42, and 43 may be made of metal, and the surface thereof may be silver or the like having higher reflectivity, or black or the like having low reflectivity. Furthermore, instead of the substantially quadrangular pyramid shape, it may be formed in a conical shape.

従って、この第２実施形態の照明器具４０においては、内側に位置する反射板４２、４３の反射面４６が有する遮光角α４よりも、外側に位置する反射板４１の反射面４７が有する遮光角α５の方が小さく設定されている。そのため、この第２実施形態の照明器具４０においては、外側に位置するＬＥＤ光源１２からの光が、より側方に向けて照射され、内側に位置するＬＥＤ光源１２からの光が、より側方へ向けて照射されない。
これにより、この第２実施形態の照明器具４０においては、照射面の均性度を向上できる。 Therefore, in the luminaire 40 of the second embodiment, the light shielding angle of the reflecting surface 47 of the reflecting plate 41 located on the outer side than the light shielding angle α4 of the reflecting surface 46 of the reflecting plates 42 and 43 located on the inner side. α5 is set smaller. Therefore, in the lighting fixture 40 of this 2nd Embodiment, the light from the LED light source 12 located outside is irradiated more toward the side, and the light from the LED light source 12 located inside is more lateral. It is not irradiated towards.
Thereby, in the lighting fixture 40 of this 2nd Embodiment, the uniformity degree of an irradiation surface can be improved.

また、この第２実施形態の照明器具４０においては、幅方向の外側に位置する反射板４１の下方開口部４４の開口寸法Ｌ４が、内側に位置する反射板４２、４３の下方開口部４４、４５の開口寸法Ｌ５よりも大きい。そのため、この第２実施形態の照明器具４０においては、外側に位置するＬＥＤ光源１２からの光が、内側に位置するＬＥＤ光源１２の遮光特性および反射特性に影響を与えない。
これにより、この第２実施形態の照明器具４０においては、全体としてグレアの悪化を最小限に抑え、下面照度の低下を防止できる。 Moreover, in the lighting fixture 40 of this 2nd Embodiment, the opening dimension L4 of the lower opening part 44 of the reflecting plate 41 located in the outer side of the width direction is the lower opening part 44 of the reflecting plates 42 and 43 located inside, It is larger than the opening dimension L5 of 45. Therefore, in the lighting fixture 40 of this 2nd Embodiment, the light from the LED light source 12 located outside does not affect the light-shielding characteristic and reflection characteristic of the LED light source 12 located inside.
Thereby, in the lighting fixture 40 of this 2nd Embodiment, the deterioration of glare can be suppressed to the minimum as a whole, and the fall of bottom surface illumination intensity can be prevented.

As illustrated in FIG. 24, the lighting fixture 50 according to the third embodiment of the present invention includes a reflecting plate 51 positioned outside in the width direction orthogonal to the longitudinal direction of the reflecting plate forming member 16, and positioned inside the reflecting plate 51. The reflecting plate 52 and the reflecting plate 53 positioned inside the reflecting plate 52 are the same in the width direction, and the vertical size is changed only on the outside.

すなわち、照明器具５０は、反射板形成部材１６に有する最外側の反射板５１、反射板５１の内側に位置する反射板５２、反射板５２の内側に位置する反射板５３のそれぞれの下方開口部５４の開口寸法Ｌ６が全て同一である。そして、照明器具５０は、最外部の反射板５１における外側部の上端部からの突出寸法Ｌ７が、内側に位置する反射板５２および反射板５３の上端部からの突出寸法Ｌ８よりも長さ寸法Ｌ９だけ短く設定されている。   That is, the luminaire 50 includes the outermost reflecting plate 51 included in the reflecting plate forming member 16, the reflecting plate 52 positioned inside the reflecting plate 51, and the lower openings of the reflecting plate 53 positioned inside the reflecting plate 52. All the 54 opening dimensions L6 are the same. And as for the lighting fixture 50, the protrusion dimension L7 from the upper end part of the outer side part in the outermost reflecting plate 51 is longer than the protrusion dimension L8 from the upper end part of the reflecting plate 52 and the reflecting plate 53 located inside. It is set shorter by L9.

従って、この第３実施形態の照明器具５０においては、最外部の反射板５１における外側部の上端部からの突出寸法Ｌ７が、内側に位置する反射板５２および反射板５３の上端部からの突出寸法Ｌ８よりも短く設定されている。
これにより、この第３実施形態の照明器具５０においては、外側に位置するＬＥＤ光源１２からの光が、より側方に向けて照射され、内側に位置するＬＥＤ光源１２からの光が、より側方へ向けて照射されず、照射面の均性度を向上できる。 Therefore, in the lighting fixture 50 of the third embodiment, the protruding dimension L7 from the upper end of the outer portion of the outermost reflecting plate 51 is the protruding from the upper ends of the reflecting plate 52 and the reflecting plate 53 located on the inner side. It is set shorter than the dimension L8.
Thereby, in the lighting fixture 50 of this 3rd Embodiment, the light from the LED light source 12 located outside is irradiated toward the side more, and the light from the LED light source 12 located inside is on the more side. The uniformity of the irradiated surface can be improved.

また、この第３実施形態の照明器具５０においては、外側に位置するＬＥＤ光源１２からの光が、内側に位置するＬＥＤ光源１２の遮光特性および反射特性に影響を与えない。
これにより、この第３実施形態の照明器具５０においては、全体としてグレアの悪化を最小限に抑え、下面照度の低下を防止できる。 Moreover, in the lighting fixture 50 of this 3rd Embodiment, the light from the LED light source 12 located outside does not affect the light-shielding characteristic and reflection characteristic of the LED light source 12 located inside.
Thereby, in the lighting fixture 50 of this 3rd Embodiment, the deterioration of glare can be suppressed to the minimum as a whole, and the fall of lower surface illumination intensity can be prevented.
