CC sectional drawing of a), (c) is DD sectional drawing of Fig.1 (a). 2A is a cross-sectional view taken along the line AA in FIG. 1A, and FIG. 2B is a cross-sectional view taken along the line BB in FIG. The outline of the configuration of the system ceiling 900 on which the T-bar mounting lighting device 100 is installed will be described with reference to FIGS. 1 and 2.

図１（ａ）に示すように、システム天井９００は、Ｔバー５００、Ｔバー取付用照明器具１００、Ｔバー取付金具５２０を備える。Ｔバー５００は、システム天井の下地に用いられる部材であり、格子状に組み合わせて使用される。図１（ａ）は、Ｔバー５００が格子状に組み合わされて形成される複数のロ字状領域の中の１つのロ字状領域を示している。図２（ａ）に示すように、通常、Ｔバーピッチ（ロ字状領域の一辺の長さ）は６００ｍｍまたは６４０ｍｍである。   As shown in FIG. 1A, the system ceiling 900 includes a T bar 500, a T bar mounting lighting device 100, and a T bar mounting bracket 520. The T bar 500 is a member used for the base of the system ceiling, and is used in combination in a lattice shape. FIG. 1A shows one square-shaped region among a plurality of square-shaped regions formed by combining T bars 500 in a lattice shape. As shown in FIG. 2 (a), the T-bar pitch (the length of one side of the B-shaped region) is usually 600 mm or 640 mm.

Ｔバー取付用照明器具１００は、ロ字状領域の両側部に沿って設置される。Ｔバー取付用照明器具１００は、長手方向の長さがロ字状領域の一辺の長さと略同一あるいはロ字状領域の一辺の長さよりやや短く、ロ字状領域の側部に嵌るような状態で設置される。ロ字状領域の両側に設置された２つのＴバー取付用照明器具１００の間には、天井材８００が配置される。   The T-bar mounting lighting fixture 100 is installed along both sides of the square-shaped region. The lighting device 100 for T-bar attachment has a length in the longitudinal direction that is substantially the same as the length of one side of the square-shaped region or slightly shorter than the length of one side of the square-shaped region, and fits to the side of the square-shaped region. Installed in a state. A ceiling material 800 is disposed between two T-bar mounting lighting devices 100 installed on both sides of the square-shaped region.

図１（ｂ）に示すように、Ｔバー取付用照明器具１００は、長手方向の両側部のうちの一方の側部１０１がＴバー５００に隣接している。Ｔバー取付用照明器具１００の他方の側部１０１は、天井材８００に隣接する。   As shown in FIG. 1B, in the T-bar mounting lighting device 100, one side portion 101 of both side portions in the longitudinal direction is adjacent to the T-bar 500. The other side portion 101 of the T-bar mounting lighting fixture 100 is adjacent to the ceiling material 800.

図１（ｃ）、図２（ｂ）に示すように、Ｔバー取付用照明器具１００は、長手方向の両側の端部１０２にＴバー取付金具５２０が取り付けられる。Ｔバー取付用照明器具１００は、両側の端部１０２に取り付けられたＴバー取付金具５２０によりＴバー５００に取り付けられる。   As shown in FIGS. 1C and 2B, in the T-bar mounting lighting device 100, T-bar mounting brackets 520 are mounted on the end portions 102 on both sides in the longitudinal direction. The T-bar mounting lighting fixture 100 is mounted on the T-bar 500 by T-bar mounting brackets 520 mounted on both end portions 102.

また、図１（ｂ），（ｃ）に示すように、ロ字状領域に設置された２つのＴバー取付用照明器具１００のうちの一方のＴバー取付用照明器具１００には、天面１０３の中心部近傍に、２つのＴバー取付用照明器具１００を点灯するための電源、端子台、他方のＴバー取付用照明器具１００に電源を供給するためのコネクタ接続等が配置される。他方のＴバー取付用照明器具１００には、一方のＴバー取付用照明器具１００から電源をもらうためのコネクタ接続等が配置される。   Further, as shown in FIGS. 1B and 1C, one of the two T-bar mounting lighting fixtures 100 installed in the square-shaped region has a top surface. In the vicinity of the central portion 103, a power source for lighting the two T-bar mounting lighting fixtures 100, a terminal block, a connector connection for supplying power to the other T-bar mounting lighting fixture 100, and the like are arranged. The other T-bar mounting lighting fixture 100 is provided with a connector connection for receiving power from one T-bar mounting lighting fixture 100.

図３は、本実施の形態１に係るＴバー取付用照明器具１００の詳細断面図である。図４は、（ａ）が図３のＡ部拡大図、（ｂ）が（ａ）において光の照射状態を示す図である。Ｔバー取付用照明器具１００は、本体３００と透光カバー４００とを備える。   FIG. 3 is a detailed cross-sectional view of T-bar attachment lighting device 100 according to the first embodiment. 4A is an enlarged view of a portion A in FIG. 3, and FIG. 4B is a diagram illustrating a light irradiation state in FIG. The T-bar mounting lighting device 100 includes a main body 300 and a translucent cover 400.

本体３００は、光源の照射方向Ｐ側が開口している断面コ字状である。本体３００は、長手方向に長く、短手方向に短い、細長い形状である。本体３００の開口を本体開口部３１０とする。本体３００は、両側の側部１０１の本体端部（すなわち、本体開口部３１０の両側部）につば部３２０を備える（図４参照）。つば部３２０は、本体３００の外方向に略水平に形成されている。   The main body 300 has a U-shaped cross section that is open on the irradiation direction P side of the light source. The main body 300 has an elongated shape that is long in the longitudinal direction and short in the lateral direction. The opening of the main body 300 is referred to as a main body opening 310. The main body 300 includes flange portions 320 at the main body end portions of the side portions 101 on both sides (that is, both side portions of the main body opening 310) (see FIG. 4). The collar portion 320 is formed substantially horizontally in the outward direction of the main body 300.

本体３００の材質は、金属であり、例えば、アルミニウムである。本体３００の材質は、放熱の面からアルミニウムが好ましく、また、塗装してあると放熱性が高まる。   The material of the main body 300 is a metal, for example, aluminum. The material of the main body 300 is preferably aluminum from the viewpoint of heat dissipation, and if it is painted, the heat dissipation is enhanced.

本体３００の底面１０４には、ＬＥＤ２１０（光源）を備えるＬＥＤ基板２００が配置されている。ＬＥＤ基板２００は、複数個のＬＥＤ２１０を搭載している。ＬＥＤ基板２００は、低Ｗ（１Ｗ以下）のＬＥＤ２１０を多く搭載している。そのため、ＬＥＤ２１０間のピッチが狭い方が透光カバー４００（後述する）が均一に光っているように見えて好ましい。ＬＥＤ基板２００は、本体３００にネジ止めされている（図示なし）。本体３００が器具（Ｔバー取付用照明器具１００）の外郭を兼ねているとより放熱性がよい。   On the bottom surface 104 of the main body 300, an LED substrate 200 including an LED 210 (light source) is disposed. The LED substrate 200 has a plurality of LEDs 210 mounted thereon. The LED substrate 200 is equipped with many low-W (1 W or less) LEDs 210. Therefore, it is preferable that the pitch between the LEDs 210 is narrower because the translucent cover 400 (described later) appears to shine uniformly. The LED substrate 200 is screwed to the main body 300 (not shown). When the main body 300 also serves as the outer shell of the fixture (T-bar mounting lighting fixture 100), the heat dissipation is better.

透光カバー４００は、ＬＥＤ２１０の発する光を通過させる透光カバーであって本体開口部３１０を覆うように本体３００に取り付けられる。透光カバー４００は、つば部３２０の縁部３２１（図４（ａ）参照）から照射方向Ｐに向かって形成された透光カバー側面４１０（カバー側部）と、本体開口部３１０を覆うように透光カバー側面４１０から連続して形成されたカバー面部４３０とを備える。   The translucent cover 400 is a translucent cover that allows light emitted from the LEDs 210 to pass through, and is attached to the main body 300 so as to cover the main body opening 310. The translucent cover 400 covers the translucent cover side surface 410 (cover side portion) formed in the irradiation direction P from the edge portion 321 (see FIG. 4A) of the collar portion 320 and the main body opening 310. And a cover surface portion 430 formed continuously from the translucent cover side surface 410.

透光カバー４００の透光カバー側面４１０の上端は、本体３００の内側方向に屈折してつば部３２０の上面と当接するカバー係止部４２０が形成されている（図４（ａ）参照）。   The upper end of the translucent cover side surface 410 of the translucent cover 400 is formed with a cover locking portion 420 that is refracted in the inner direction of the main body 300 and comes into contact with the upper surface of the collar portion 320 (see FIG. 4A).

すなわち、透光カバー４００は、略水平面であるカバー係止部４２０から連続して略垂直下方に屈折した透光カバー側面４１０と、透光カバー側面４１０の下端から連続して水平方向に屈折したカバー面部４３０とを備えている。透光カバー側面４１０とカバー面部４３０との境界部分（境界部、結合部、屈折部）をコーナー部４４０とする。   That is, the translucent cover 400 is continuously refracted in the horizontal direction continuously from the lower end of the translucent cover side surface 410 and the translucent cover side surface 410 refracted substantially vertically downward continuously from the cover engaging portion 420 which is a substantially horizontal plane. Cover surface portion 430. A boundary portion (boundary portion, coupling portion, refraction portion) between the translucent cover side surface 410 and the cover surface portion 430 is a corner portion 440.

本体３００への透光カバー４００の取付方法は、例えば、つば部３２０とカバー係止部４２０とを当接させながらスライドさせて取り付けるものである。本体３００の長手方向の一方の端部１０２から透光カバー４００を挿入し、透光カバー４００を本体３００の長手方向の他方の端部１０２方向にスライドさせて本体３００に取り付ける。   For example, the translucent cover 400 is attached to the main body 300 by sliding the collar portion 320 and the cover locking portion 420 while abutting them. The translucent cover 400 is inserted from one end 102 in the longitudinal direction of the main body 300, and the translucent cover 400 is slid in the direction of the other end 102 in the longitudinal direction of the main body 300 and attached to the main body 300.

透光カバー４００の材質は、例えば、アクリル、ポリカーボネート樹脂である。透光カバー４００には、乳白色、マット、透明等の種類がある。透光カバー４００が均一に光って見えるためには、乳白色の透光カバー４００が好ましい。また、透光カバー４００には、ＬＥＤ２１０を保護するための保護カバーの役目もある。使用者（作業者）等が、ＬＥＤ２１０、ＬＥＤ基板２００等に直接さわることができないようにするためである。   The material of the translucent cover 400 is, for example, acrylic or polycarbonate resin. The translucent cover 400 includes types such as milky white, matte, and transparent. The translucent cover 400 is preferably milky white so that the translucent cover 400 appears to shine uniformly. The translucent cover 400 also serves as a protective cover for protecting the LED 210. This is to prevent a user (operator) or the like from directly touching the LED 210, the LED substrate 200, or the like.

Ｔバー５００は、上述したように断面逆Ｔバー字状である。Ｔバー５００の下端面（照射方向Ｐ側の面）をＴバー意匠面５１０とする。天井の視認することができる面（天井面）を天井意匠面６００とする。Ｔバー意匠面５１０は、天井意匠面６００と略同一面上にあり、天井意匠面６００の一部として視認することができる面である。天井材８００の下端面（天井材下端面８１０）も、天井意匠面６００と略同一面上にあり、天井意匠面６００の一部として視認することができる面である。   The T bar 500 has an inverted T-bar cross section as described above. A lower end surface (surface on the irradiation direction P side) of the T bar 500 is defined as a T bar design surface 510. A surface (ceiling surface) from which the ceiling can be visually recognized is defined as a ceiling design surface 600. The T-bar design surface 510 is substantially the same surface as the ceiling design surface 600 and is a surface that can be visually recognized as a part of the ceiling design surface 600. The lower end surface (ceiling member lower end surface 810) of the ceiling material 800 is also substantially on the same plane as the ceiling design surface 600, and is a surface that can be visually recognized as a part of the ceiling design surface 600.

Ｔバー取付用照明器具１００は、透光カバー側面４１０とカバー面部４３０との境界部分（境界部、結合部、屈折部）であるコーナー部４４０が、Ｔバー意匠面５１０と略同一面上にある。カバー面部４３０は、コーナー部４４０から略水平方向に屈折した面であるので、カバー面部４３０もＴバー意匠面５１０と略同一面上にある。つまり、カバー面部４３０は、Ｔバー意匠面５１０及び天井材下端面８１０と略同一面上にある。すなわち、カバー面部４３０は、Ｔバー意匠面５１０及び天井材下端面８１０とともに天井意匠面６００の一部を構成し、天井意匠面６００として視認することができる面である。   In the T-bar mounting lighting fixture 100, a corner portion 440 that is a boundary portion (boundary portion, coupling portion, refracting portion) between the translucent cover side surface 410 and the cover surface portion 430 is substantially flush with the T-bar design surface 510. is there. Since the cover surface portion 430 is a surface that is refracted in a substantially horizontal direction from the corner portion 440, the cover surface portion 430 is also substantially flush with the T-bar design surface 510. That is, the cover surface portion 430 is substantially flush with the T-bar design surface 510 and the ceiling material lower end surface 810. That is, the cover surface portion 430 constitutes a part of the ceiling design surface 600 together with the T-bar design surface 510 and the ceiling material lower end surface 810, and is a surface that can be visually recognized as the ceiling design surface 600.

したがって、本実施の形態のシステム天井９００では、天井材下端面８１０とカバー面部４３０とＴバー意匠面５１０とが視認できることとなる。これにより、システム天井９００の意匠性が向上する。   Therefore, in the system ceiling 900 of the present embodiment, the ceiling material lower end surface 810, the cover surface portion 430, and the T-bar design surface 510 can be visually recognized. Thereby, the designability of the system ceiling 900 improves.

図４（ｂ）に示すように。ＬＥＤ２１０から発せられる光は、コーナー部４４０にまで到達する。ＬＥＤ２１０から出た光は、本体３００に遮光されないように透光カバー４００と本体３００との間にはスペースがある。よって、透光カバー４００は、Ｔバー意匠面５１０または、天井材下端面８１０より上側まで光る。したがって、カバー面部４３０全体が発光することになり、Ｔバー取付用照明器具１００の発光範囲Ｒが広くなり、意匠性とともに発光効率も向上する。また、システム天井９００において、つば部３２０等により光が遮光されることが無くなるのでシステム天井９００全体の意匠性、発光効率も向上する。   As shown in FIG. The light emitted from the LED 210 reaches the corner portion 440. There is a space between the translucent cover 400 and the main body 300 so that the light emitted from the LED 210 is not shielded by the main body 300. Therefore, the translucent cover 400 shines to the upper side of the T-bar design surface 510 or the ceiling material lower end surface 810. Therefore, the entire cover surface portion 430 emits light, the light emission range R of the T-bar mounting lighting device 100 is widened, and the luminous efficiency is improved as well as the design. Further, in the system ceiling 900, light is not shielded by the collar portion 320 and the like, so that the design and luminous efficiency of the entire system ceiling 900 are improved.

図５は、本実施の形態１に係る透光カバー４００と本体３００の取付構造のバリエーション（ａ）〜（ｄ）を示す図である。   FIG. 5 is a view showing variations (a) to (d) of the mounting structure of the translucent cover 400 and the main body 300 according to the first embodiment.

以上のように、本実施の形態に係るＴバー取付用照明器具１００によれば、Ｔバー取付用照明器具１００の発光範囲Ｒが広くなり、意匠性とともに発光効率も向上する。また、システム天井９００において、本体３００のつば部３２０等により光が遮光されることが無くなるのでシステム天井９００全体の意匠性、発光効率も向上し、より快適なシステム天井９００を構成することができる。   As described above, according to the T-bar mounting lighting fixture 100 according to the present embodiment, the light emission range R of the T-bar mounting lighting fixture 100 is widened, and the luminous efficiency is improved as well as the design. Further, in the system ceiling 900, since light is not blocked by the flange portion 320 of the main body 300, the design and luminous efficiency of the entire system ceiling 900 are improved, and a more comfortable system ceiling 900 can be configured. .

実施の形態２．
図６は、本実施の形態２に係るＴバー取付用照明器具１００の詳細断面図である。実施の形態１の図３で説明したＴバー取付用照明器具１００と異なる構成は、透光カバー４００ａの形状である。図６では、図３と同様の構成部については同一の符号を付し、その説明を省略する。 Embodiment 2. FIG.
FIG. 6 is a detailed cross-sectional view of T-bar mounting lighting device 100 according to the second embodiment. A configuration different from the T-bar mounting lighting device 100 described in FIG. 3 of the first embodiment is the shape of the translucent cover 400a. In FIG. 6, the same components as those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted.

図６に示すように、透光カバー４００ａは、中央部分が照射方向Ｐ側の反対側に凹んで形成されたカバー凹部４７０を有する形状である。カバー凹部４７０は、カバー面部４３０の短手方向の中央軸近傍が、長手方向に沿って凹んだ凹みである。カバー凹部の断面形状は、コ字状、逆凹字状である。カバー面部４３０は、コーナー部４４０から水平方向に形成された面と連結する角部４５１から照射方向Ｐの反対方向へ略垂直に延設されたカバー側面部４５２を備える。そして、カバー面部４３０は、カバー側面部４５２の上端部から水平方向に形成されたカバー上面部４５３を備える。   As shown in FIG. 6, the translucent cover 400a has a shape having a cover concave portion 470 formed with a central portion recessed on the opposite side to the irradiation direction P side. The cover recess 470 is a recess in which the vicinity of the central axis in the short direction of the cover surface portion 430 is recessed along the longitudinal direction. The cross-sectional shape of the cover concave portion is a U-shape or an inverted concave shape. The cover surface portion 430 includes a cover side surface portion 452 extending substantially perpendicularly from the corner portion 451 connected to the surface formed in the horizontal direction from the corner portion 440 in the direction opposite to the irradiation direction P. The cover surface portion 430 includes a cover upper surface portion 453 formed in the horizontal direction from the upper end portion of the cover side surface portion 452.

図６に示すように、透光カバー４００のカバー上面部４５３の部分は、主に、ＬＥＤ２１０の直接光が照射される領域（ＬＥＤ直接光範囲Ｒ１）である。また、透光カバー４００のカバー側面部４５２の部分は、主に、ＬＥＤ２１０の間接光が照射される領域（ＬＥＤ間接光範囲Ｒ２）である。間接光とは、ＬＥＤ２１０からの光が本体側部３１１の内側により反射して透光カバー４００から照射される光である。   As shown in FIG. 6, the cover upper surface portion 453 of the translucent cover 400 is mainly a region (LED direct light range R <b> 1) irradiated with direct light from the LED 210. Moreover, the part of the cover side surface part 452 of the translucent cover 400 is a region (LED indirect light range R2) mainly irradiated with indirect light of the LED 210. The indirect light is light that is emitted from the translucent cover 400 when the light from the LED 210 is reflected by the inside of the main body side portion 311.

本実施の形態の透光カバー４００ａによれば、発光範囲にＬＥＤ直接光範囲Ｒ１とＬＥＤ間接光範囲Ｒ２とを形成することができる。したがって、Ｔバー取付用照明器具１００の透光カバーの輝度（眩しさ）が高い場合には、この透光カバー４００ａの形状が有効である。カバー側面部４５２から発せられる光は、本体３００の反射による間接光になるため輝度は低く抑えられる。   According to the translucent cover 400a of the present embodiment, the LED direct light range R1 and the LED indirect light range R2 can be formed in the light emission range. Therefore, when the brightness (dazzle) of the translucent cover of the T-bar mounting lighting fixture 100 is high, the shape of the translucent cover 400a is effective. Since the light emitted from the cover side surface portion 452 becomes indirect light by the reflection of the main body 300, the luminance is suppressed low.

図７は、本実施の形態２に係るＴバー取付用照明器具１００の詳細断面図であり、（ａ）は透光カバー４００ｂの形状の一例を示す図、（ｂ）は図７（ｂ）とは本体３００ｂの形状が異なる例を示す図である。   FIG. 7 is a detailed cross-sectional view of the T-bar mounting lighting apparatus 100 according to the second embodiment, in which (a) is a diagram illustrating an example of the shape of the translucent cover 400b, and (b) is FIG. 7 (b). Is a diagram showing an example in which the shape of the main body 300b is different.

図７（ａ）に示すように、透光カバー４００ｂは、両側のカバー側面部４５２ｂが内側方向（本体３００の短手方向の中心方向）に傾斜している形状である。透光カバー４００ｂでは、カバー側面部４５２ｂの幅（長さ）Ｌ２が、傾斜がない場合の幅（長さ）Ｌ１より長くなる。したがって、透光カバー４００ｂでは、カバー側面部４５２ｂにより多くの光が入るため垂直の場合（図６参照）よりも、透光カバー４００ｂから照射される間接光が多くなり、眩しさをより抑えることができる。さらに、透光カバー４００ｂを備えるＴバー取付用照明器具１００では、カバー側面部４５２ｂに、より多くの光が入るため垂直の場合よりも明るくなる。   As shown in FIG. 7A, the translucent cover 400b has a shape in which the cover side surface portions 452b on both sides are inclined inward (center direction in the short direction of the main body 300). In the translucent cover 400b, the width (length) L2 of the cover side surface portion 452b is longer than the width (length) L1 when there is no inclination. Therefore, in the translucent cover 400b, more light enters the cover side surface portion 452b, and therefore, more indirect light is emitted from the translucent cover 400b than in the vertical case (see FIG. 6), thereby further suppressing glare. Can do. Further, in the T-bar mounting lighting device 100 including the translucent cover 400b, more light enters the cover side surface portion 452b, so that it becomes brighter than in the vertical case.

図７（ｂ）に示すように、本体３００ｂは、両側の本体側部３１１ｂが内側方向（本体３００の短手方向の中心方向）に傾斜している形状である。本体３００ｂでは、本体側部３１１ｂの幅（長さ）が、傾斜がない場合の幅（長さ）より長くなる。したがって、本体側部３１１ｂにより多くの光が反射する。このように、本体３００ｂに傾斜をもうけることによりＬＥＤ２１０の光を制御して透光カバー４００（４００ａ，４００ｂ）に効率良く光を入れることができる。   As illustrated in FIG. 7B, the main body 300b has a shape in which the main body side portions 311b on both sides are inclined inward (center direction in the short direction of the main body 300). In the main body 300b, the width (length) of the main body side portion 311b is longer than the width (length) when there is no inclination. Therefore, a lot of light is reflected by the main body side portion 311b. In this way, by providing the main body 300b with an inclination, the light of the LED 210 can be controlled and light can be efficiently put into the translucent cover 400 (400a, 400b).

上述した図６及び図７に示すＴバー取付用照明器具１００でも、コーナー部４４０の位置は、Ｔバー意匠面５１０と略同一面上にある。   6 and 7 described above, the corner portion 440 is located substantially on the same plane as the T-bar design surface 510.

実施の形態３．
図８は、本実施の形態３に係るＴバー取付用照明器具１００の詳細断面図である。実施の形態１の図３で説明したＴバー取付用照明器具１００と異なる構成は、透光カバー４００ｃの形状である。図８では、図３と同様の構成部については同一の符号を付し、その説明を省略する。 Embodiment 3 FIG.
FIG. 8 is a detailed cross-sectional view of T-bar mounting lighting apparatus 100 according to the third embodiment. A configuration different from the T-bar mounting lighting device 100 described in FIG. 3 of the first embodiment is the shape of the light-transmitting cover 400c. In FIG. 8, the same components as those in FIG. 3 are denoted by the same reference numerals, and the description thereof is omitted.

図８に示すように、透光カバー４００ｃでは、カバー面部４３０に対応する面が照射方向Ｐに膨らんだ曲面となっている。この曲面をカバー曲面部４５５とする。実施の形態１，２と同様にコーナー部４４０は天井意匠面６００と同一面上にある。カバー曲面部４５５は、一方のコーナー部４４０から他方のコーナー部４４０までが、照射方向Ｐに膨らんだ曲面となっている。したがって、カバー曲面部４５５は天井意匠面６００から突出している。   As shown in FIG. 8, in the translucent cover 400c, the surface corresponding to the cover surface portion 430 is a curved surface that swells in the irradiation direction P. This curved surface is referred to as a cover curved surface portion 455. As in the first and second embodiments, the corner portion 440 is on the same plane as the ceiling design surface 600. The cover curved surface portion 455 is a curved surface that swells in the irradiation direction P from one corner portion 440 to the other corner portion 440. Therefore, the cover curved surface portion 455 protrudes from the ceiling design surface 600.

本実施の形態に係るＴバー取付用照明器具１００によれば、カバー面部４３０をカバー曲面部４５５としたことにより、ＬＥＤ２１０と透光カバー４００ｃとの距離を離すことができる（Ｌ３＜Ｌ４）。したがって、視認できるカバー面部４３０（カバー曲面部４５５）がより面発光しているように見え、発光効率が向上する。   According to lighting apparatus 100 for T-bar attachment according to the present embodiment, the distance between LED 210 and translucent cover 400c can be increased by using cover surface portion 430 as cover curved surface portion 455 (L3 <L4). Accordingly, the visible cover surface portion 430 (cover curved surface portion 455) appears to emit more light, and the light emission efficiency is improved.

また、本実施の形態に係るＴバー取付用照明器具１００によれば、透光カバー４００ｃ（カバー曲面部４５５）がＴバー意匠面５１０及び天井材下端面８１０よりも下面に出ているため、透光カバー４００ｃの拡散光により天井面（天井材下端面８１０）も照らすことができ、より明るくなる。   Further, according to the T-bar mounting lighting apparatus 100 according to the present embodiment, the translucent cover 400c (cover curved surface portion 455) protrudes on the lower surface than the T-bar design surface 510 and the ceiling material lower end surface 810. The ceiling surface (ceiling material lower end surface 810) can also be illuminated by the diffused light of the translucent cover 400c, and it becomes brighter.
