The details of the cover portion 230 will be described with reference to FIGS. 6 to 10. As shown in FIG. 9, the cover portion 230 is formed substantially symmetrically with the central axis 11 as the axis of symmetry. Although the left side side of the central axis 11 will be mainly described, since the cover portion 230 is formed line-symmetrically with the central axis 11, the configuration described also applies to the right side of the central axis 11.

カバー部２３０は、主部２３１、カバー側壁部２３２、第一の支持部である上側支持部２３３、第二の支持部である下側支持部２３４を備える。ここで、主部２３１およびカバー側壁部２３２の全体をカバー本体部２３０ａと称する。主部２３１、一対のカバー側壁部２３２及び一対の傾斜部２３２−１は、全体が同じ材料、例えば透光性材料で形成されている。この材料は、光の拡散性と、透光性とを有する。なお一対の傾斜部２３２−１は、光を反射する反射材料で形成されてもよい。また、上側支持部２３３及び下側支持部２３４は、全体が同じ材料、例えば反射材料で形成されている。この材料は遮光性と高反射性を有し、主部２３１等を形成する材料とは異なる。図９に示すように、主部２３１は、長手方向Ｘを法線方向とする断面の形状が、カバー側壁部の立ち上がる方向と反対方向（Ｚ方向）に凸となる凸断面形状２３０Ｄをなす。凸断面形状２３０Ｄとは図９の主部２３１の断面形状をいう。
（１）主部２３１は発光素子基板２１０から照射される光を拡散する。

Here, the entire main portion 231 and the cover side wall portion 232 are referred to as a cover main body portion 230a. The main portion 231 and the pair of cover side wall portions 232 and the pair of inclined portions 232-1 are entirely made of the same material, for example, a translucent material. This material has both light diffusivity and light transmissivity. The pair of inclined portions 232-1 may be formed of a reflective material that reflects light. Further, the upper support portion 233 and the lower support portion 234 are entirely made of the same material, for example, a reflective material. This material has light-shielding property and high reflectivity, and is different from the material forming the main portion 231 and the like. As shown in FIG. 9, the main portion 231 has a convex cross-sectional shape 230D in which the shape of the cross section with the longitudinal direction X as the normal direction is convex in the direction opposite to the rising direction (Z direction) of the cover side wall portion. The convex cross-sectional shape 230D refers to the cross-sectional shape of the main portion 231 in FIG.
(1) The main portion 231 diffuses the light emitted from the light emitting element substrate 210.
(2) The cover side wall portions 232 are arranged as a pair at both ends of the main portion 231 to form a side surface of the cover portion 230.

（主部２３１）
主部２３１は、発光素子基板２１０が照射する光を透過させ拡散させるものであり、発光素子基板２１０を覆う凸形状をしている。主部２３１は、一方のカバー側壁部２３２の端部Ｂ（端部２３１ａに一致）、他方のカバー側壁部２３２の端部Ｂ（端部２３１ｂに一致）を繋ぐように配設されている。言い換えれば、カバー側壁部２３２は端部Ａと端部Ｂとの間に形成されている。 (Main part 231)
The main portion 231 transmits and diffuses the light emitted by the light emitting element substrate 210, and has a convex shape covering the light emitting element substrate 210. The main portion 231 is arranged so as to connect the end portion B (corresponding to the end portion 231a) of one cover side wall portion 232 and the end portion B (corresponding to the end portion 231b) of the other cover side wall portion 232. In other words, the cover side wall portion 232 is formed between the end portion A and the end portion B.

（カバー側壁部２３２）
カバー側壁部２３２は、主部２３１の両端（端部Ｂ）に対になるよう配設され、主部２３１の両端（端部Ｂ）を基端部として主部２３１の凸となる方向と反対方向にそれぞれ立ち上がる。カバー側壁部２３２は、器具本体１００の凹部１１１の第一の側壁部１１３−１、第二の側壁部１１３−２と略平行に形成されている。また、対になるカバー側壁部２３２の外側の面の距離である寸法Ｌ１（図９）は、図８に示す凹部１１１の巾である寸法Ｌ２（第一の側壁部１１３−１の内側面１１３−１ａと、第二の側壁部１１３−２の内側面１１３−２ａとの短手方向の距離）に対して、器具本体１００の凹部１１１に挿入可能に略同等の寸法に形成される。なお、挿入可能に略同等の寸法とは、光源ユニット２００が凹部１１１との間に形成される隙間をなるべく抑え、挿入できる寸法である。例えば寸法Ｌ１が５９ｍｍに対して寸法Ｌ２が６０ｍｍなどである。つまり、照明器具３００は、器具本体１００に光源ユニット２００が取り付けられた状態において、凹部１１１の短手方向Ｙにおける内側面１１３−１ａと、内側面１１３−２ａとの距離である凹部内側巾寸法Ｌ２から、カバー部２３０の短手方向Ｙにおける一方の先端部２３２ｂの外側面２３２ｃと他方の先端部２３２ｂの外側面２３２ｃとの距離である先端部外側巾寸法Ｌ１（図９）を引いた寸法が、０ｍｍ以上３ｍｍ以下である。つまり、照明器具３００は、器具本体１００に光源ユニット２００が取り付けられた状態において、図８の断面において、左右の各隙間を同じとすれば、各隙間は０ｍｍ以上１．５ｍｍ以下の範囲である。 (Cover side wall 232)
The cover side wall portion 232 is arranged so as to be paired with both ends (end B) of the main portion 231 and is opposite to the convex direction of the main portion 231 with both ends (end B) of the main portion 231 as the base end portion. Stand up in each direction. The cover side wall portion 232 is formed substantially parallel to the first side wall portion 113-1 and the second side wall portion 113-2 of the recess 111 of the instrument body 100. Further, the dimension L1 (FIG. 9), which is the distance between the outer surfaces of the paired cover side wall portions 232, is the dimension L2 (the inner surface 113 of the first side wall portion 113-1), which is the width of the recess 111 shown in FIG. The distance between -1a and the inner side surface 113-2a of the second side wall portion 113-2) is formed to have substantially the same dimensions so that it can be inserted into the recess 111 of the instrument body 100. It should be noted that the dimensions that are substantially equivalent to the insertability are the dimensions that the light source unit 200 can be inserted by suppressing the gap formed between the light source unit 200 and the recess 111 as much as possible. For example, the dimension L1 is 59 mm and the dimension L2 is 60 mm. That is, in the lighting fixture 300, when the light source unit 200 is attached to the fixture main body 100, the recess inner width dimension which is the distance between the inner side surface 113-1a and the inner side surface 113-2a of the recess 111 in the lateral direction Y. The dimension obtained by subtracting the tip outer width dimension L1 (FIG. 9) which is the distance between the outer surface 232c of one tip 232b and the outer surface 232c of the other tip 232b in the lateral direction Y of the cover 230. However, it is 0 mm or more and 3 mm or less. That is, in the lighting fixture 300, when the light source unit 200 is attached to the fixture body 100, if the left and right gaps are the same in the cross section of FIG. 8, each gap is in the range of 0 mm or more and 1.5 mm or less. ..

また、図８に示すように、カバー側壁部２３２は、光源ユニット２００の器具本体１００への取り付けが完了して光源ユニット２００の一部が器具本体１００の凹部１１１に収納された際に、凹部１１１の開口部１１１ａ（図２の矩形ａｂｃｄ）から外側に露出する。器具本体１００への取付完了時に光源ユニット２００の一部が凹部１１１に収納された状態において、各上側支持部２３３が凹部１１１に収納される。 Further, as shown in FIG. 8, the cover side wall portion 232 is recessed when the light source unit 200 is attached to the fixture body 100 and a part of the light source unit 200 is housed in the recess 111 of the fixture body 100.

また、図８に示すように、各カバー側壁部２３２は、少なくとも一部が、発光素子２１２よりもＺ方向に位置する。このため発光素子２１２の発した光を各カバー側壁部２３２で拡散できるので、照明効果が向上する。光源ユニット２００は、各カバー側壁部２３２をつかまれて方向Ｚに引っ張られた場合、凹部１１１から引き出される。 Further, as shown in FIG. 8, at least a part of each cover side wall portion 232 is located in the Z direction with respect to the light emitting element 212. Therefore, the light emitted by the light emitting element 212 can be diffused by each cover side wall portion 232, so that the lighting effect is improved. When the light source unit 200 is grabbed by each cover side wall portion 232 and pulled in the direction Z, the light source unit 200 is pulled out from the recess 111.

図７に示すように、カバー側壁部２３２の周辺には破線で示す操作空間５００が確保されている。操作空間５００によって、着脱時に容易に光源ユニット２００のカバー側壁部２３２を掴むことができる。 As shown in FIG. 7, an operation space 500 shown by a broken line is secured around the side wall portion 232 of the cover. The operation space 500 makes it possible to easily grip the cover side wall portion 232 of the light source unit 200 at the time of attachment / detachment.

Next, the configuration of the instrument body 100 will be described. As shown in FIG. 4, the instrument main body 100 includes recesses 111, inclined portions 114-1 and 114-2, and lid portions 120-1 and 120-2.
(1) The recess 111 is formed substantially in the center along the longitudinal direction X.

(3) The lid portions 120-1 and 120-2 are arranged at both ends in the longitudinal direction, and cover the recesses 111 and the inclined portions 114-1 and 114-2 at the ends in the longitudinal direction X.
(4) The instrument main body 100 includes a spring portion 130 and a terminal block 140. The spring portion 130 is arranged on the flat plate portion 112 and is connected to the connecting metal fitting 250 arranged on the light source unit 200.

器具本体１００は、凹部１１１を備える。図４に示すように、凹部１１１は、長尺状の平板部１１２と、平板部１１２の長手方向Ｘに沿う一方の平板端部１１２ａと他方の平板端部１１２ｂとからそれぞれ立ち上がる第一の側壁部１１３−１及び第二の側壁部１１３−２とを有する凹形状をなし光源ユニット２００の一部を収納する。平板部１１２は天井などの取付部に当接する。開口部１１１ａの周部には開口縁部１１１ｂ（図８）が配設されている。平板部１１２には、バネ部１３０と端子台１４０が配設されている。また平板部１１２には、商用電源からの電力供給を受ける為の電源線を引き込む電源引込孔１１２ｃと、ボルトなどの取付材により被取付部へ固定する為の固定孔１１２ｄが形成されている。 The instrument body 100 includes a recess 111.

図１０は、主部２３１の厚み変化を説明するための模式的なカバー断面図である。図１１〜図１３は、いずれも、主部２３１の厚み変化を説明するための図である。 FIG. 10 is a schematic cover sectional view for explaining a change in the thickness of the main portion 231. 11 to 13 are all views for explaining the change in thickness of the main portion 231.

（１）図１０に示すように、カバー部２３０の主部２３１は、両側領域２３６の厚みが、中央領域２３７よりも薄い。この構成により、主部２３１から出射される光の照射を主部２３１の短手方向Ｙにおいて、簡易な構成で均一に近づけることができる。中央領域２３７とは、主部２３１の凸断面形状２３０Ｄの短手方向Ｙにおいて、両側領域２３６に挟まれる領域である。
両側領域２３６は、中央領域２３７の両側に存在する。両側領域２３６は、左側の両側領域２３６は一方の端部２３１ａを含み、右側の両側領域２３６は他方の端部２３１ｂを含む領域である。
（２）図１０は、主部２３１の厚みという構造から、主部２３１から出射される光の照射を主部２３１の短手方向Ｙにおいて簡易な構成で均一に近づける構成であるが、主部２３１は、一方の端部２３１ａと他方の端部２３１ｂとを含む短手方向Ｙの両側領域２３６の光の拡散度が、短手方向Ｙの中央領域２３７よりも小さい構成であればよい。拡散度の調整は、主部２３１の厚み変化に限らず、あるいは厚みの変化に加え、主部２３１の表面加工や、主部２３１を構成する材料の成分構成で拡散度を調整してもよい。
（３）また、主部２３１は拡散度の観点からではなく光の透過率の観点から構成されてもよい。つまり両側領域２３６の光の透過率が中央領域２３７よりも大きい構成でもよい。透過率の場合も、主部２３１の厚みの他、主部２３１の表面加工や、主部２３１を構成する材料の成分構成で拡散度を調整してもよい。拡散度、透過率、厚みのいずれか一つ、あるいはいずれか二つ、あるいは三つ全部によって、簡易な構成で、短手方向Ｙの光の照射の均一化を向上させることができる。 (1) As shown in FIG. 10, in the main portion 231 of the cover portion 230, the thickness of the side region 236 is thinner than that of the central region 237. With this configuration, the irradiation of the light emitted from the main portion 231 can be uniformly approached in the lateral direction Y of the main portion 231 with a simple configuration. The central region 237 is a region sandwiched between both side regions 236 in the lateral direction Y of the convex cross-sectional shape 230D of the main portion 231.
The bilateral regions 236 are present on both sides of the central region 237. In the bilateral region 236, the left bilateral region 236 includes one end 231a, and the right bilateral region 236 includes the other end 231b.
(2) FIG. 10 shows a structure in which the irradiation of light emitted from the main portion 231 is uniformly approached in the lateral direction Y of the main portion 231 with a simple configuration due to the structure of the thickness of the main portion 231. The 231 may have a configuration in which the light diffusivity of the light diffusivity of both side regions 236 in the lateral direction Y including the one end portion 231a and the other end portion 231b is smaller than that of the central region 237 in the lateral direction Y. The degree of diffusivity is not limited to the change in the thickness of the main part 231, or in addition to the change in the thickness, the degree of diffusivity may be adjusted by the surface processing of the main part 231 and the composition of the materials constituting the main part 231. ..
(3) Further, the main portion 231 may be configured not from the viewpoint of diffusivity but from the viewpoint of light transmittance. That is, the light transmittance of the bilateral region 236 may be larger than that of the central region 237. In the case of transmittance, in addition to the thickness of the main portion 231 the diffusivity may be adjusted by the surface processing of the main portion 231 and the component composition of the material constituting the main portion 231. Depending on any one, two, or all three of the diffusivity, the transmittance, and the thickness, it is possible to improve the uniformity of light irradiation in the lateral direction Y with a simple configuration.

図１１は、主部２３１の厚み変化を説明するための図である。図１１は、図８に相当する断面図である。「相当する」としたのは、図８ではハーネスクランプ２７０が現れている断面であるが図１１では連結金具２５０が現れている断面であるためである。カバー部２３０としては同じ断面である。
（１）図１１では、主部２３１は、凸断面形状２３０Ｄの外側表面２３１−２の曲率半径Ｒ２が、凸断面形状２３０Ｄの内側表面２３１−１の曲率半径Ｒ１と異なる断面図である。図１１の場合、一方の端部２３１ａと他方の端部２３１ｂとの間に挟まれる１点鎖線の上側（曲率半径Ｒ１）と下側（曲率半径Ｒ２）とが、それぞれ主部２３１の内側表面２３１−１と、外側表面２３１−２をなす。図１１では主部２３１の中央領域２３７の厚みが、両側領域２３６の厚みよりも厚い。
（２）図１１に示す主部２３１では、凸断面形状２３０Ｄの外側表面２３１−２の曲率半径Ｒ２が、凸断面形状２３０Ｄの内側表面２３１−１の曲率半径Ｒ１よりも小さい。つまりＲ２＜Ｒ１である。
（３）図１１に示す主部２３１では、凸断面形状２３０Ｄの外側表面２３１−２の曲率中心Ｏ（Ｒ２）が、凸断面形状２３０Ｄの内側表面２３１−１の曲率中心Ｏ（Ｒ１）と異なる位置する。具体的には、曲率中心Ｏ（Ｒ２）は中心軸１１上において、曲率中心Ｏ（Ｒ１）の下側にある。図１１の主部２３１では、両側領域２３６の厚みが、中央領域２３７よりも薄くなるので、主部２３１から出射される光の照射を主部２３１の短手方向Ｙにおいて、均一に近づけることができる。 FIG. 11 is a diagram for explaining a change in the thickness of the main portion 231. FIG. 11 is a cross-sectional view corresponding to FIG. The reason for "corresponding" is that the cross section in which the harness clamp 270 appears in FIG. 8 is the cross section in which the connecting metal fitting 250 appears in FIG. The cover portion 230 has the same cross section.
(1) In FIG. 11, the main portion 231 is a cross-sectional view in which the radius of curvature R2 of the outer surface 231-2 of the convex cross-sectional shape 230D is different from the radius of curvature R1 of the inner surface 231-1 of the convex cross-sectional shape 230D. In the case of FIG. 11, the upper side (radius of curvature R1) and the lower side (radius of curvature R2) of the alternate long and short dash line sandwiched between one end 231a and the other end 231b are the inner surfaces of the main portion 231, respectively. It forms 231-1 and the outer surface 231-2. In FIG. 11, the thickness of the central region 237 of the main portion 231 is thicker than the thickness of the side region 236.
(2) In the main portion 231 shown in FIG. 11, the radius of curvature R2 of the outer surface 231-2 of the convex cross-sectional shape 230D is smaller than the radius of curvature R1 of the inner surface 231-1 of the convex cross-sectional shape 230D. That is, R2 <R1.
(3) In the main portion 231 shown in FIG. 11, the center of curvature O (R2) of the outer surface 231-2 of the convex cross-sectional shape 230D is different from the center of curvature O (R1) of the inner surface 231-1 of the convex cross-sectional shape 230D. To position. Specifically, the center of curvature O (R2) is on the central axis 11 and below the center of curvature O (R1). In the main portion 231 of FIG. 11, since the thickness of the side region 236 is thinner than that of the central region 237, the irradiation of the light emitted from the main portion 231 can be uniformly approached in the lateral direction Y of the main portion 231. it can.

図１２は、主部２３１の厚み変化を説明するための図である。図１２は、図１１と同じ断面図である。図１２の場合も図１１と同様に、一方の端部２３１ａと他方の端部２３１ｂとの間に挟まれる１点鎖線の上側（曲率半径Ｒ１）と下側（曲率半径Ｒ２）とが、それぞれ主部２３１の内側表面２３１−１と、外側表面２３１−２をなす。図１２の主部２３１は、凸断面形状２３０Ｄの外側表面２３１−２の曲率半径Ｒ２が、凸断面形状２３０Ｄの内側表面２３１−１の曲率半径Ｒ１と同じ長さであり、図示はしていなが曲率半径Ｒ２の曲率中心Ｏ（Ｒ２）は、中心軸１１上において、曲率半径Ｒ１の曲率中心Ｏ（Ｒ１）の下側にある。図１２の主部２３１でも、両側領域２３６の厚みが、中央領域２３７よりも薄くなるので、主部２３１から出射される光の照射を主部２３１の短手方向Ｙにおいて、均一に近づけることができる。 FIG. 12 is a diagram for explaining a change in the thickness of the main portion 231. FIG. 12 is the same cross-sectional view as that of FIG. In the case of FIG. 12, similarly to FIG. 11, the upper side (radius of curvature R1) and the lower side (radius of curvature R2) of the alternate long and short dash line sandwiched between one end 231a and the other end 231b are respectively. It forms an inner surface 231-1 and an outer surface 231-2 of the main portion 231. In the main portion 231 of FIG. 12, the radius of curvature R2 of the outer surface 231-2 of the convex cross-sectional shape 230D is the same as the radius of curvature R1 of the inner surface 231-1 of the convex cross-sectional shape 230D, and is not shown. The center of curvature O (R2) having a radius of curvature R2 is below the center of curvature O (R1) having a radius of curvature R1 on the central axis 11. Even in the main portion 231 of FIG. 12, the thickness of the side region 236 is thinner than that of the central region 237, so that the irradiation of the light emitted from the main portion 231 can be uniformly approached in the lateral direction Y of the main portion 231. it can.

図１３は、主部２３１の厚み変化を説明するための、さらに別の図である。図１３は、図１１と同じ断面図である。図１３では、前述のように主部２３１は、断面の形状が、カバー側壁部２３２の立ち上がる方向と反対のＺ方向に凸となる凸断面形状２３０Ｄ形状である。主部２３１は、短手方向Ｙを左右方向とした場合に中心軸１１を対象軸とする左右対称の形状となる上記の凸断面形状２３０Ｄをなす。発光素子２１２は、図１３に示す断面において、凸断面形状２３０Ｄの中心軸１１と交わる。主部２３１は、図１３の断面において、中心軸１１が発光素子２１２の発光面２１２Ｓと交わる交点Ｐと、凸断面形状２３０Ｄの内側表面２３１−１との距離Ｌｋ（Ｌ１，Ｌ２等）に応じて、距離Ｌｋをなす内側表面２３１−１の箇所Ｌｐ１，Ｌｐ２における厚みｔｋ（ｋ＝１，２）が変化する。図１３では距離Ｌ１における箇所Ｌｐ１での厚みをｔ１、距離Ｌ２における箇所Ｌｐ２でお厚みをｔ２とすると、ｔ１＞ｔ２である。なお距離Ｌｋをなす箇所Ｌｐｋ（ｋ＝１，２、・・・）における主部２３１の厚みｔｋとは、距離Ｌｋをなす内側表面２３１−１の箇所Ｌｐｋにおける接線に対する直角方向の厚みである。距離Ｌｋは図１４の角度θで決まる長さである。角度θが大きいほど距離Ｌｋは長くなり、距離Ｌｋが長いほど、距離Ｌｋにおける主部２３１の厚みｔｋは薄くなる。よって、図１３の主部２３１でも、両側領域２３６の厚みが、中央領域２３７よりも薄くなるので、主部２３１から出射される光の照射を主部２３１の短手方向Ｙにおいて、均一に近づけることができる。なお、図１１、図１２のＬ１，Ｌ２、θ等も図１３と同じ意味であり、図１４の説明は図１１、図１２にも当てはまる。 FIG. 13 is yet another diagram for explaining the change in the thickness of the main portion 231. FIG. 13 is the same cross-sectional view as that of FIG. In FIG. 13, as described above, the main portion 231 has a convex cross-sectional shape 230D in which the cross-sectional shape is convex in the Z direction opposite to the rising direction of the cover side wall portion 232. The main portion 231 has the above-mentioned convex cross-sectional shape 230D having a symmetrical shape with the central axis 11 as the target axis when the lateral direction Y is the left-right direction. The light emitting element 212 intersects the central axis 11 of the convex cross-sectional shape 230D in the cross section shown in FIG. The main portion 231 corresponds to the distance Lk (L1, L2, etc.) between the intersection P where the central axis 11 intersects the light emitting surface 212S of the light emitting element 212 and the inner surface 231-1 of the convex cross-sectional shape 230D in the cross section of FIG. Therefore, the thickness tk (k = 1, 2) at the locations Lp1 and Lp2 of the inner surface 231-1 forming the distance Lk changes. In FIG. 13, assuming that the thickness at the location Lp1 at the distance L1 is t1 and the thickness at the location Lp2 at the distance L2 is t2, t1> t2. The thickness tk of the main portion 231 at the portion Lpk forming the distance Lk (k = 1, 2, ...) Is the thickness in the direction perpendicular to the tangent line at the portion Lpk of the inner surface 231-1 forming the distance Lk. The distance Lk is a length determined by the angle θ in FIG. The larger the angle θ, the longer the distance Lk, and the longer the distance Lk, the thinner the thickness tk of the main portion 231 at the distance Lk. Therefore, even in the main portion 231 of FIG. 13, the thickness of the side region 236 is thinner than that of the central region 237, so that the irradiation of the light emitted from the main portion 231 is uniformly approached in the lateral direction Y of the main portion 231. be able to. Note that L1, L2, θ, etc. in FIGS. 11 and 12 have the same meaning as in FIG. 13, and the description of FIG. 14 also applies to FIGS. 11 and 12.

（下側支持部２３４の形状）
図９において、中心軸１１の左側にある側壁部２３３ａは、傾斜部２３２−１の立ち上がりの終端部Ｅに形成された上下壁形状部２２３３ａである。上下壁形状部２２３３ａは、終端部ＥにおいてＺ方向の反対方向に延びる壁形状の上側壁形状部２２３３−１と、Ｚ方向に延びる壁形状の下側壁形状部２２３３−２とを有する。中心軸１１の右側にも中心軸１１に対象な上下壁形状部２２３３ａが形成されており、上下壁形状部２２３３ａは一対である。中心軸１１の左の下側壁形状部２２３３−２のＺ向の終端部からは、相手（中心軸１１の右側）の下側壁形状部２２３３−２に向かって延びる下側支持部２３４（延出部）が形成されており、中心軸１１の右側も同じである。そして、カバー側壁部２３２は、相手のカバー側壁部２３２に対向する対向面に接続する部材が存在しない。図９の中心軸１１の右側を例に説明すれば、下側支持部２３４とカバー側壁部２３２のカバー側壁部２３２の対向面との間には、空間２３８が存在する。つまり、下側支持部２３４には二点鎖線で示すような、カバー側壁部２３２と接続する方向に延びる逆向延出部は存在しない。
よって図８に示すように、発光素子２１２から出た光は空間２３８から傾斜部２３２−１へ到達する。よって傾斜部２３２−１と器具本体１００との隙間（図８）が暗部になることを防止できる。 (Shape of lower support part 234)
In FIG. 9, the side wall portion 233a on the left side of the central axis 11 is an upper and lower wall-shaped portion 2233a formed at the rising end portion E of the inclined portion 232-1. The upper and lower wall-shaped portion 2233a has a wall-shaped upper wall-shaped portion 2233-1 extending in the opposite direction in the Z direction at the terminal portion E, and a wall-shaped lower wall-shaped portion 2233-2 extending in the Z direction. The upper and lower wall-shaped portions 2233a corresponding to the central axis 11 are also formed on the right side of the central axis 11, and the upper and lower wall-shaped portions 2233a are a pair. Lower support portion 234 (extending) extending from the Z-oriented end portion of the lower side wall shape portion 2233-2 on the left side of the central axis 11 toward the lower side wall shape portion 2233-2 on the other side (right side of the central axis 11). Part) is formed, and the same applies to the right side of the central axis 11. The cover side wall portion 232 does not have a member connected to the facing surface facing the cover side wall portion 232 of the other party. Explaining the right side of the central axis 11 of FIG. 9 as an example, a space 238 exists between the lower support portion 234 and the facing surface of the cover side wall portion 232 of the cover side wall portion 232. That is, the lower support portion 234 does not have a reverse extending portion extending in the direction of connecting to the cover side wall portion 232 as shown by the alternate long and short dash line.
Therefore, as shown in FIG. 8, the light emitted from the light emitting element 212 reaches the inclined portion 232-1 from the space 238. Therefore, it is possible to prevent the gap (FIG. 8) between the inclined portion 232-1 and the instrument main body 100 from becoming a dark portion.

図８に示す寸法ｈ１は、Ｚ方向（中心軸１１方向）における、発光素子２１２の発光面２１２Ｓと中心軸１１との交点Ｐから、中心軸１１上における主部２３１の外側表面までの距離である。図９に示す寸法ｈ２は、カバー側壁部２３２の端部Ｂと、端部Ｂに対して反対方向（Ｚ方向の反対方向）に位置するカバー側壁部２３２の立ち上がりの終端部である端部Ａとの、中心軸１１方向における距離である。
Ｒは、主部２３１の外側表面の曲率半径であり、曲率中心Ｏ（Ｒ）は中心軸１１上にある。
Ｗは短手方向Ｙにおける、一対のカバー側壁部２３２の立ち上がりのそれぞれの終端部である端部Ａどうし外側距離である。
条件（１）、条件（２）のいずれかの条件が成立することで、カバー側壁部２３２における上方（Ｚ方向と反対向き方向）の照射を増やすことができる。 According to h1 shown in FIG. 8 and h2, W, R shown in FIG. 9, the dimensions of the light source unit 200 can be defined as follows.
The convex cross-sectional shape 230D has a convex cross-sectional shape of 230D.
Condition (1): h2 / h1 ≧ 0.340 and h1 <R,
When,
Condition (2): h1 / W ≧ 0.245 and h1 <R,
It is assumed that one of the two conditions (1) and (2) is satisfied.
Here, h1 is the dimension shown in FIG. 8, and h2 and W are the dimensions shown in FIG.
The dimension h1 shown in FIG. 8 is the distance from the intersection P of the light emitting surface 212S of the light emitting element 212 and the central axis 11 in the Z direction (direction of the central axis 11) to the outer surface of the main portion 231 on the central axis 11. is there. The dimension h2 shown in FIG. 9 is the end portion A of the end portion B of the cover side wall portion 232 and the rising end portion of the cover side wall portion 232 located in the opposite direction (opposite direction in the Z direction) to the end portion B. Is the distance in the direction of the central axis 11.
R is the radius of curvature of the outer surface of the main portion 231 and the center of curvature O (R) is on the central axis 11.
W is the outer distance between the end portions A, which are the end portions of the rising ends of the pair of cover side wall portions 232 in the lateral direction Y.
When either the condition (1) or the condition (2) is satisfied, the irradiation of the cover side wall portion 232 in the upward direction (direction opposite to the Z direction) can be increased.

図６、図８、図９に示すように、カバー部２３０は反射リブ２３３ｃ（リブ部）を有する。反射リブ２３３ｃは、上側壁形状部２２３３−１から長手方向Ｘにわたり相手の上側壁形状部２２３３−１の方向と反対方向に突き出している。
反射リブ２３３ｃをカバー部２３０に設け、カバー部２３０を出た光を反射リブ２３３ｃで反射させることで、カバー部２３０と器具本体１００との隙間（図８）が長手方向Ｘにわたり「暗部すじ」になることを低減できる。よって照明器具３００の意匠性を向上できる。一対の傾斜部２３２−１、一対のカバー側壁部２３２及び主部２３１は乳白色とし、一対の反射リブ２３３ｃ及び内側面１１３−２ａ，１１３−１ａは白色とする。また、一対の傾斜部２３２−１、一対のカバー側壁部２３２及び主部２３１は光透過性と光拡散性を有し、一対の反射リブ２３３ｃ及び内側面１１３−２ａ，１１３−１ａは高い反射特性を有する。なお、この実施の形態では反射リブ２３３ｃは一対の上側壁形状部２２３３−１の両方に形成されているが、反射リブ２３３ｃは、一対の上側壁形状部２２３３−１のうちの少なくとも一方に形成されることでもよい。そして、一対の傾斜部２３２−１は白色として高い反射特性を有するようにしてもよい。反射リブ２３３ｃは反射材料で形成される。 As shown in FIGS. 6, 8 and 9, the cover portion 230 has a reflective rib 233c (rib portion). The reflective rib 233c protrudes from the upper side wall shape portion 2233-1 in the longitudinal direction X in the direction opposite to the direction of the other upper side wall shape portion 2233-1.
The reflective rib 233c is provided on the cover portion 230, and the light emitted from the cover portion 230 is reflected by the reflective rib 233c, so that the gap (FIG. 8) between the cover portion 230 and the instrument main body 100 is "dark portion streaks" over the longitudinal direction X. Can be reduced. Therefore, the design of the lighting fixture 300 can be improved. The pair of inclined portions 232-1, the pair of cover side wall portions 232 and the main portion 231 are milky white, and the pair of reflective ribs 233c and the inner side surfaces 113-2a and 113-1a are white. Further, the pair of inclined portions 232-1, the pair of cover side wall portions 232 and the main portion 231 have light transmission and light diffusivity, and the pair of reflective ribs 233c and the inner side surfaces 113-2a and 113-1a have high reflection. Has characteristics. In this embodiment, the reflective ribs 233c are formed on both of the pair of upper side wall shape portions 2233-1, but the reflective ribs 233c are formed on at least one of the pair of upper side wall shape portions 2233-1. It may be done. Then, the pair of inclined portions 232-1 may be white and have high reflection characteristics. The reflective rib 233c is made of a reflective material.

図８、図９に示すように、一対のカバー側壁部２３２は、相手のカバー側壁部２３２に向かって凹形状に凹んでいる。つまり図８の中心軸１１の左側のカバー側壁部２３２に着目すれば、このカバー側壁部２３２は端部Ａ，端部ＢをＺ方向の両端として、中心軸１１右側のカバー側壁部２３２に向かって凹む形状である。
このように、カバー部２３０は、一対のカバー側壁部２３２が相手のカバー側壁部２３２に向かって凹形状に凹む形状である。よって、この凹形状を作業者がつかむことで、器具本体１００への光源ユニット２００の取付時の作業性、器具本体１００からの光源ユニット２００の取り外し時の作業性が向上する。
カバー側壁部２３２の凹形状に関する寸法は、次のように規定することができる。
カバー側壁部２３２の凹形状は、例えば、
条件（３）：Ｄ≦５ｍｍ、
を基本とし、
条件（４）：ｈ２／Ｗ≧０．０９、かつ、Ｒ２≦５ｍｍ、
または、
条件（５）：ｈ２／Ｗ≧０．０９、かつ、Ｒ２≧５ｍｍ、
と規定することができる。ｈ２，Ｄ，Ｗ，Ｒ２は、いずれも図９に示す寸法である。図９に示すように、寸法ｈ２は、カバー側壁部２３２の端部Ｂと、端部Ｂに対して反対方向（反Ｚ方向）に位置するカバー側壁部２３２の立ち上がりの終端部である端部Ａとの、中心軸１１方向における距離である。Ｄは前記カバー側壁部の凹形状の最大の深さである。Ｒ２は、カバー側壁部２３２の外側表面の曲率半径である。またＷは短手方向Ｙにおける、一対のカバー側壁部２３２の立ち上がりのそれぞれの終端部である端部Ａどうしの外側距離である。
上述した凹形状に関する寸法は、器具本体１００への光源ユニット２００の取付時の作業性と器具本体１００からの光源ユニット２００の取り外し時の作業性を考慮して規定されており、具体的には凹形状をつかむ作業者の手指の形状と寸法を考慮した寸法である。
そして、条件（４）、条件（５）のいずれの条件を選択するかについては、器具本体１００に光源ユニット２００を取り付ける取付強度を考慮する。
さらに、カバー側壁部２３２は、端部Ａ，端部ＢをＲ２より小さい曲面形状として、作業時に指先に加わるストレスを緩和することが好ましい。 As shown in FIGS. 8 and 9, the pair of cover side wall portions 232 are concavely recessed toward the cover side wall portion 232 of the other. That is, paying attention to the cover side wall portion 232 on the left side of the central axis 11 in FIG. 8, the cover side wall portion 232 faces the cover side wall portion 232 on the right side of the central axis 11 with the end portions A and B as both ends in the Z direction. It has a dented shape.
As described above, the cover portion 230 has a shape in which the pair of cover side wall portions 232 are recessed toward the mating cover side wall portion 232. Therefore, when the operator grasps this concave shape, the workability when the light source unit 200 is attached to the instrument body 100 and the workability when the light source unit 200 is removed from the instrument body 100 are improved.
The dimensions of the cover side wall portion 232 with respect to the concave shape can be specified as follows.
The concave shape of the cover side wall portion 232 is, for example,
Condition (3): D ≤ 5 mm,
Based on
Condition (4): h2 / W ≧ 0.09 and R2 ≦ 5 mm,
Or
Condition (5): h2 / W ≧ 0.09 and R2 ≧ 5 mm,
Can be specified. h2, D, W, and R2 are all the dimensions shown in FIG. As shown in FIG. 9, the dimension h2 is the end portion B of the cover side wall portion 232 and the end portion which is the rising end portion of the cover side wall portion 232 located in the opposite direction (anti-Z direction) to the end portion B. It is the distance from A in the direction of the central axis 11. D is the maximum depth of the concave shape of the side wall portion of the cover. R2 is the radius of curvature of the outer surface of the cover side wall portion 232. Further, W is the outer distance between the end portions A, which are the end portions of the rising ends of the pair of cover side wall portions 232 in the lateral direction Y.
The dimensions related to the concave shape described above are defined in consideration of workability when the light source unit 200 is attached to the instrument body 100 and workability when the light source unit 200 is removed from the instrument body 100, and specifically. The dimensions take into consideration the shape and dimensions of the operator's finger that grips the concave shape.
Then, as to which of the conditions (4) and (5) is selected, the mounting strength of attaching the light source unit 200 to the fixture body 100 is taken into consideration.
Further, it is preferable that the cover side wall portion 232 has an end portion A and an end portion B having a curved surface shape smaller than R2 to relieve stress applied to the fingertips during work.

図８、図９に示すように、係合部２３３ｂの下方で、上下壁形状部２２３３ａに傾斜部２３２−１が接続するので、カバー部２３０が保持部２２０に装着状態では、カバー部２３０が保持部２２０からより脱落しにくくなる。
図８、図９に示す断面における傾斜部２３２−１が立ち上がる方向と、上側壁形状部２２３３−１とのなす角θ１は鈍角である（θ１＞９０°）。また、図８、図９に示す断面における傾斜部２３２−１が立ち上がる方向と、下側壁形状部２２３３−２とのなす角θ２は鋭角である（θ２＜９０°）。このため、カバー部２３０が保持部２２０からより脱落しにくくなるという効果とともに、上下壁形状部２２３３ａと傾斜部２３２−１との接続箇所の破壊のおそれを低減できる。そして、器具本体１００から光源ユニット２００の取り外しを行う際に、カバー部２３０が保持部２２０から外れてしまったり、カバー部２３０を破損させてしまったりするおそれが少ないため、器具本体１００から光源ユニット２００の取り外しを行う際の作業性が向上する。
なお、上側壁形状部２２３３−１と傾斜部２３２−１の終端部（端部Ａ）との接続箇所は、成形性などを考慮して直角、鈍角、鋭角のいずれかを選択できる。 As shown in FIGS. 8 and 9, since the inclined portion 232-1 is connected to the upper and lower wall-shaped portions 2233a below the engaging portion 233b, the cover portion 230 is attached to the holding portion 220 when the cover portion 230 is attached to the holding portion 220. It becomes more difficult to fall off from the holding portion 220.
The angle θ1 formed by the direction in which the inclined portion 232-1 rises in the cross section shown in FIGS. 8 and 9 and the upper side wall shape portion 2233-1 is an obtuse angle (θ1> 90 °). Further, the angle θ2 formed by the direction in which the inclined portion 232-1 rises in the cross section shown in FIGS. 8 and 9 and the lower side wall shape portion 2233-2 is an acute angle (θ2 <90 °). Therefore, the cover portion 230 is less likely to fall off from the holding portion 220, and the risk of breaking the connection portion between the upper and lower wall-shaped portions 2233a and the inclined portion 232-1 can be reduced. Then, when the light source unit 200 is removed from the fixture body 100, there is little risk that the cover portion 230 will come off from the holding portion 220 or the cover portion 230 will be damaged. Therefore, the light source unit from the fixture body 100 is less likely to be damaged. Workability when removing the 200 is improved.
The connection point between the upper side wall shape portion 2233-1 and the end portion (end portion A) of the inclined portion 232-1 can be selected from a right angle, an obtuse angle, and an acute angle in consideration of moldability and the like.
