Note that the substantially equivalent dimensions so that the light source unit 200 can be inserted are dimensions in which the gap formed between the light source unit 200 and the recess 111 can be suppressed as much as possible and can be inserted. For example, the dimension L2 is 60 mm while the dimension L1 is 59 mm. That is, when the light source unit 200 is attached to the fixture main body 100, the lighting fixture 300 has a recess inner width dimension that is a distance between the inner side surface 113-1a and the inner side surface 113-2a in the short direction Y of the recess 111. A dimension obtained by subtracting the tip outer width dimension L1 (FIG. 9), which is the distance between the outer face 232c of one tip 232b and the outer face 232c of the other tip 232b in the short direction Y of the cover 230, from L2. Is 0 mm or more and 3 mm or less. That is, in the state where the light source unit 200 is attached to the fixture main body 100, if the left and right gaps are the same in the cross section of FIG. 8, the lighting fixture 300 has a 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。   As shown in FIG. 8, the cover side wall portion 232 has a concave portion when the attachment of the light source unit 200 to the appliance main body 100 is completed and a part of the light source unit 200 is stored in the concave portion 111 of the appliance main body 100. It is exposed to the outside from an opening 111a (rectangular abcd in FIG. 2) of 111. In a state where a part of the light source unit 200 is housed in the recess 111 when the attachment to the apparatus main body 100 is completed, each upper support portion 233 is housed in the recess 111.

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。   As shown in FIG. 8, at least a part of each cover side wall 232 is located in the Z direction relative to the light emitting element 212. For this reason, the light emitted from the light emitting element 212 can be diffused by each cover side wall portion 232, so that the illumination effect is improved. The light source unit 200 is pulled out from the concave portion 111 when each of the cover side walls 232 is grasped and pulled in the direction Z.

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 indicated by a broken line is secured around the cover side wall portion 232. The operation space 500 allows the cover side wall portion 232 of the light source unit 200 to be easily grasped during attachment and detachment.

A pair is formed from the tip (end) of the inclined portion 232-1 formed to be inclined in the direction of H.232. The inclined portion 232-1 rises with the end portion A (terminal portion) of the side wall portion 232 as a base end portion and is inclined toward the central portion in the short direction, and the upper end portion is provided at the end portion where the inclined rising ends. 233 are connected.

The lower convex portion 234a has a shape that is convex in the Z direction and covers the surface 221a of the holding portion 220 to which the light emitting element substrate 210 is attached.
(2) The edge of the lower convex portion 234a in the short direction Y forms a lower pressing portion 234b that presses the surface 221a of the mounting portion 221.

上側支持部233の係合部233bと、下側支持部234の下側押圧部234bとが、保持部220の第一の側面部222−1の先端部および取付部221を挟持することで、カバー部230は保持部220に固定される。   The engagement portion 233b of the upper support portion 233 and the lower pressing portion 234b of the lower support portion 234 sandwich the distal end portion of the first side surface portion 222-1 of the holding portion 220 and the attachment portion 221.

(Instrument body 100)
Next, the configuration of the instrument body 100 will be described. As shown in FIG. 4, the instrument main body 100 includes a concave portion 111, inclined portions 114-1, 114-2, and lid portions 120-1, 120-2.
(1) The concave portion 111 is formed substantially at the center along the longitudinal direction X.
(2) The inclined portions 114-1 and 114-2 are inclined so as to be separated from each other in the direction of the attached portion from each of the long sides of the opening 111 a of the concave portion 111, and widen.
(3) The lids 120-1 and 120-2 are provided at both ends in the longitudinal direction, and cover the concave portion 111 and the inclined portions 114-1 and 114-2 at the ends in the longitudinal direction X.
(4) The device main body 100 includes a spring portion 130 and a terminal block 140. The spring portion 130 is disposed on the flat plate portion 112 and is connected to the connection fitting 250 disposed 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 device main body 100 includes a concave portion 111. As shown in FIG. 4, the concave portion 111 has a long flat plate portion 112, and first side walls rising from one flat plate end portion 112 a and the other flat plate end portion 112 b along the longitudinal direction X of the flat plate portion 112. A part of the light source unit 200 is housed in a concave shape having a portion 113-1 and a second side wall portion 113-2.

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 thickness of the main portion 231. 11 to 13 are diagrams for explaining a change in thickness of the main portion 231. FIG.

(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 both side regions 236 is smaller than that of the central region 237. With this configuration, the irradiation of the light emitted from the main portion 231 can be made uniform in the lateral direction Y of the main portion 231 with a simple configuration. The central region 237 is a region sandwiched between the two side regions 236 in the lateral direction Y of the convex section 230D of the main portion 231.
The side regions 236 exist on both sides of the center region 237. The two side regions 236 are regions in which the left side region 236 includes one end 231a and the right side region 236 includes the other end 231b.
(2) FIG. 10 shows a structure in which the irradiation of light emitted from the main part 231 is made uniform and uniform in the short direction Y of the main part 231 because of the thickness of the main part 231. 231 may have a configuration in which the light diffusivity of both side regions 236 in the short direction Y including one end 231a and the other end 231b is smaller than the central region 237 in the short direction Y. The adjustment of the diffusivity is not limited to the change in the thickness of the main part 231, or may be adjusted by the surface processing of the main part 231 or the component composition of the material constituting the main part 231 in addition to the change in the thickness. .
(3) The main portion 231 may be configured not from the viewpoint of the degree of diffusion but from the viewpoint of light transmittance. That is, a configuration in which the light transmittance of the both side regions 236 is larger than that of the central region 237 may be employed. Also in the case of the transmittance, the degree of diffusion may be adjusted by the surface processing of the main portion 231 or the component configuration of the material constituting the main portion 231 in addition to the thickness of the main portion 231. With one of the diffusivity, transmittance, and thickness, or any two, or all three, uniformization of light irradiation in the short direction Y can be improved 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 why “corresponding” is used is that the cross section in which the harness clamp 270 appears in FIG. 8 but the cross section in which the connecting fitting 250 appears in FIG. The cover section 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 section 230D is different from the radius of curvature R1 of the inner surface 231-1 of the convex section 230D. In the case of FIG. 11, the upper side (the radius of curvature R1) and the lower side (the 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 surface of the main part 231 respectively. 231-1 and an outer surface 231-2. In FIG. 11, the thickness of the central region 237 of the main portion 231 is larger than the thickness of both side regions 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 section 230D is smaller than the radius of curvature R1 of the inner surface 231-1 of the convex section 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 section 230D is different from the center of curvature O (R1) of the inner surface 231-1 of the convex section 230D. To position. Specifically, the center of curvature O (R2) is located below the center of curvature O (R1) on the central axis 11. In the main portion 231 of FIG. 11, the thickness of the both side regions 236 is smaller than that of the central region 237, so that the irradiation of light emitted from the main portion 231 can be made uniform in the short 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 thickness of the main portion 231. FIG. 12 is the same cross-sectional view as FIG. In the case of FIG. 12, similarly to FIG. 11, the upper side (the radius of curvature R1) and the lower side (the radius of curvature R2) of the one-dot chain line sandwiched between one end 231a and the other end 231b are respectively An inner surface 231-1 and an outer surface 231-2 of the main portion 231 are formed. In the main part 231 of FIG. 12, the radius of curvature R2 of the outer surface 231-2 of the convex section 230D is the same as the radius of curvature R1 of the inner surface 231-1 of the convex section 230D, and is not shown. The center of curvature O (R2) having the radius of curvature R2 is below the center of curvature O (R1) having the radius of curvature R1 on the central axis 11. Also in the main portion 231 of FIG. 12, the thickness of the both side regions 236 is smaller than that of the central region 237, so that irradiation of light emitted from the main portion 231 can be made uniform in the short 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 still another diagram for describing a change in the thickness of the main portion 231. FIG. 13 is the same cross-sectional view as FIG. In FIG. 13, as described above, the main portion 231 has a convex cross-sectional shape 230 </ b> D 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-described convex cross-sectional shape 230D that is symmetrical with respect to the central axis 11 when the short direction Y is the left-right direction. The light emitting element 212 intersects with the central axis 11 of the convex sectional shape 230D in the cross section shown in FIG. The main part 231 corresponds to the distance Lk (L1, L2, etc.) between the intersection P at which 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 sectional shape 230D in the cross section of FIG. Accordingly, the thickness tk (k = 1, 2) at the points Lp1, Lp2 of the inner surface 231-1 forming the distance Lk changes. In FIG. 13, t1> t2, where t1 is the thickness at the location Lp1 at the distance L1 and t2 is the thickness at the location Lp2 at the distance L2. The thickness tk of the main portion 231 at the location Lpk (k = 1, 2,...) Forming the distance Lk is a thickness perpendicular to the tangent at the location Lpk on 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 part 231 at the distance Lk. Therefore, also in the main portion 231 of FIG. 13, the thickness of the both side regions 236 is smaller than that of the central region 237, so that the irradiation of the light emitted from the main portion 231 is made uniform in the lateral direction Y of the main portion 231. be able to. Note that L1, L2, θ, and the like in FIGS. 11 and 12 have the same meaning as in FIG. 13, and the description of FIG. 14 also applies to FIGS.

(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 portion 234)
In FIG. 9, a side wall portion 233a on the left side of the center axis 11 is an upper and lower wall-shaped portion 2233a formed at a rising end portion E of the inclined portion 232-1. The upper and lower wall-shaped portions 2233a have a wall-shaped upper wall-shaped portion 2233-1 and a wall-shaped lower wall-shaped portion 2233-2 extending in the Z direction at the terminal end E. Upper and lower wall-shaped portions 2233a which are symmetrical 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. A lower supporting portion 234 (extending from the Z-direction end of the lower wall-shaped portion 2233-2 on the left side of the central axis 11 extends toward a lower wall-shaped portion 2233-2 on the right side of the central axis 11). Portion) is formed, and the right side of the central axis 11 is the same. The cover side wall portion 232 has no member connected to an opposing surface facing the opposing cover side wall portion 232. If the right side of the central axis 11 in FIG. 9 is described as an example, a space 238 exists between the lower support portion 234 and the surface of the cover side wall portion 232 facing the cover side wall portion 232. That is, the lower support portion 234 does not have the reverse extension portion extending in the direction connected to the cover side wall portion 232 as indicated by the two-dot chain line.
Therefore, as shown in FIG. 8, light emitted from the light emitting element 212 reaches the inclined portion 232-1 from the space 238. Therefore, the gap (FIG. 8) between the inclined portion 232-1 and the appliance body 100 can be prevented from becoming a dark portion.

図8に示すh1、図9に示すh2、W、Rにより、光源ユニット200は、次のように寸法を規定することができる。
凸断面形状230Dは、

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。
With h1 shown in FIG. 8 and h2, W, and R shown in FIG. 9, the dimensions of the light source unit 200 can be defined as follows.
The convex sectional shape 230D is
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 between the light emitting surface 212S of the light emitting element 212 and the central axis 11 in the Z direction (the direction of the central axis 11) to the outer surface of the main part 231 on the central axis 11. is there. The dimension h2 shown in FIG. 9 is the end B of the cover side wall 232 and the end A which is the terminal end of the rising of the cover side wall 232 located in the opposite direction (opposite direction to the Z direction) to the end B. 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 an outer distance between the ends A, which are the respective ends of the rising of the pair of cover side walls 232 in the lateral direction Y.
By satisfying either the condition (1) or the condition (2), it is possible to increase the irradiation of the cover side wall portion 232 upward (in the direction opposite to the Z direction).

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 230 has a reflective rib 233c (rib). The reflection rib 233c protrudes from the upper wall-shaped portion 2233-1 in the longitudinal direction X in a direction opposite to the direction of the opposing upper wall-shaped portion 2233-1.
The reflection rib 233c is provided on the cover 230, and the light exiting the cover 230 is reflected by the reflection rib 233c, so that the gap (FIG. 8) between the cover 230 and the appliance main body 100 extends in the longitudinal direction X, resulting in "dark stripes". 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, 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 a light transmitting property and a light diffusing property, and the pair of reflecting ribs 233c and the inner side surfaces 113-2a, 113-1a have high reflection. Has characteristics. In this embodiment, the reflection rib 233c is formed on both of the pair of upper wall-shaped portions 2233-1. However, the reflection rib 233c is formed on at least one of the pair of upper wall-shaped portions 2233-1. It may be done. Then, the pair of inclined portions 232-1 may be configured to have high reflection characteristics as white. The reflection rib 233c is formed of a reflection 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 walls 232 are recessed toward the other cover side wall 232. That is, focusing on the cover side wall portion 232 on the left side of the center axis 11 in FIG. 8, the cover side wall portion 232 faces the cover side wall portion 232 on the right side of the center axis 11 with both ends A and B in the Z direction. The shape is concave.
In this manner, the cover 230 has a shape in which the pair of cover side walls 232 are concavely recessed toward the other cover side wall 232. Therefore, when the operator grasps the concave shape, the workability at the time of attaching the light source unit 200 to the tool body 100 and the workability at the time of removing the light source unit 200 from the tool body 100 are improved.
The dimensions relating to the concave shape of the cover side wall portion 232 can be defined 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 defined. h2, D, W, and R2 are all the dimensions shown in FIG. As shown in FIG. 9, the dimension h <b> 2 is the end B of the cover side wall 232 and the end that is the terminal end of the rising of the cover side wall 232 located in the opposite direction (the anti-Z direction) to the end B. A is the distance in the direction of the central axis 11 with respect to A. D is the maximum depth of the concave shape of the cover side wall. R2 is the radius of curvature of the outer surface of the cover side wall 232. W is an outer distance between the end portions A, which are the respective end portions of the rising of the pair of cover side wall portions 232 in the lateral direction Y.
The dimensions relating to the concave shape described above are defined in consideration of the workability when attaching the light source unit 200 to the fixture main body 100 and the workability when removing the light source unit 200 from the fixture main body 100, and specifically, This is a size in consideration of the shape and size of the fingers of the worker who grasps the concave shape. As to which of the condition (4) and the condition (5) is selected, the attachment strength of attaching the light source unit 200 to the fixture body 100 is considered.
Further, it is preferable that the end portions A and B of the cover side wall portion 232 have a curved surface shape smaller than R2 to reduce stress applied to a fingertip at the time of 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, the inclined portion 232-1 is connected to the upper and lower wall-shaped portions 2233a below the engaging portion 233b, so that when the cover portion 230 is attached to the holding portion 220, the cover portion 230 is It is more difficult for the holder 220 to fall off.
The angle θ1 between the direction in which the inclined portion 232-1 rises in the cross section shown in FIGS. 8 and 9 and the upper wall-shaped portion 2233-1 is an obtuse angle (θ1> 90 °). The angle θ2 between the direction in which the inclined portion 232-1 rises in the cross section shown in FIGS. 8 and 9 and the lower wall shape portion 2233-2 is an acute angle (θ2 <90 °). For this reason, it is possible to reduce the possibility that the connection portion between the upper and lower wall-shaped portions 2233a and the inclined portion 232-1 will be broken, in addition to the effect that the cover portion 230 is less likely to fall from the holding portion 220. When the light source unit 200 is detached from the instrument main body 100, the cover 230 is less likely to be detached from the holding part 220 or to damage the cover 230. The workability at the time of removing the 200 is improved.
The connection point between the upper wall-shaped portion 2233-1 and the end portion (end portion A) of the inclined portion 232-1 can be selected from any of a right angle, an obtuse angle, and an acute angle in consideration of formability and the like.
