(Cover part 230)
Details of the cover portion 230 will be described with reference to FIGS. As shown in FIG. 9, the cover portion 230 is formed substantially symmetrically with the central axis 11 as an axis of symmetry. Although the left side of the central axis 11 is mainly described, since the cover 230 is formed in line symmetry with the central axis 11, the configuration to be 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。

The cover portion 230 includes a main portion 231, a cover side wall portion 232, an upper support portion 233 which is a first support portion, and a lower support portion 234 which is a second support portion. Here, the entire main portion 231 and the cover side wall portion 232 will be referred to as a cover main body portion 230a. The main portion 231, the pair of cover side wall portions 232, and the pair of inclined portions 232-1 are entirely formed of the same material, for example, a translucent material. This material has diffusivity of light and translucency. Note that the pair of inclined portions 232-1 may be formed of a reflective material that reflects light. Further, the upper support 233 and the lower support 234 are entirely formed of the same material, for example, a reflective material. This material has light shielding properties 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 whose normal direction is the longitudinal direction X is convex in the direction (Z direction) opposite to the rising direction of the cover side wall portion. The convex cross-sectional shape 230D refers to the cross-sectional shape of the main portion 231 of FIG.
(1) The main portion 231 diffuses the light emitted from the light emitting element substrate 210.
(2) The cover side wall portion 232 is disposed as a pair at both ends of the main portion 231, and forms a side surface of the cover portion 230.

(4) The lower support portion 234 is a second support portion that contacts the mounting portion 221.

(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 from the light emitting element substrate 210, and has a convex shape covering the light emitting element substrate 210. The main portion 231 is disposed to connect an end B (corresponding to the end 231 a) of one cover side wall 232 and an end B (corresponding to the end 231 b) of the other cover side wall 232. In other words, the cover side wall portion 232 is formed between the end A and the end 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 disposed in a pair at both ends (end B) of the main portion 231 and opposite to the direction in which the main portion 231 is convex with the both ends (end B) of the main portion 231 as a base end. Stand up in the direction respectively. 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, dimension L1 (FIG. 9) which is the distance of the outer surface of the cover side wall portion 232 to be paired is dimension L2 (the inner side surface 113 of the first side wall portion 113-1) which is the width of the recess 111 shown in FIG. It is formed in a substantially equal size so that it can insert in crevice 111 of instrument main part 100 to -1a and distance of the transverse direction of inner side 113-2a of the 2nd side wall part 113-2. In addition, the dimension which can be inserted substantially and is equivalent is a dimension which can suppress the clearance gap formed between the light source unit 200 and the recessed part 111 as much as possible, and can insert it. For example, the dimension L2 is 60 mm, for example, while the dimension L1 is 59 mm. That is, in the state where the light source unit 200 is attached to the instrument main body 100, the lighting fixture 300 has a recess inner width dimension which is a distance between the inner side surface 113-1a and the inner side surface 113-2a in the short side direction Y of the recess 111. A dimension obtained by subtracting a tip outer width dimension L1 (FIG. 9) which is a distance between the outer surface 232c of one tip end 232b and the outer surface 232c of the other tip end 232b in the short side direction Y of the cover portion 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 main body 100 of the lighting fixture 300, if the left and right gaps are the same in the cross section of FIG. 8, the gaps are in the range of 0 mm to 1.5 mm. .

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 a recess when the attachment of the light source unit 200 to the instrument body 100 is completed and a part of the light source unit 200 is stored in the recess 111 of the instrument body 100. It is exposed to the outside from the opening 111a 111 (rectangle abcd in FIG. 2). Each upper support portion 233 is accommodated in the recess 111 in a state in which a part of the light source unit 200 is accommodated in the recess 111 when the attachment to the instrument body 100 is completed.

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 portion of each cover side wall portion 232 is positioned in the Z direction relative to the light emitting element 212. Therefore, the light emitted from the light emitting element 212 can be diffused by the cover side wall portions 232, so that the lighting effect is improved. The light source unit 200 is pulled out from the recess 111 when the cover side wall portions 232 are 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. By the operation space 500, the cover side wall portion 232 of the light source unit 200 can be easily grasped at the time of attachment and detachment.

As shown in FIG. 9, the upper support portion 233 is located above the end portion A (end portion) above the end portion A where the rising of each cover side wall portion 232 along the longitudinal direction X of the main portion 231 ends. It is formed to be a pair from the tip (end) of the inclined portion 232-1 formed to be inclined in the direction of 232. The inclined portion 232-1 rises with an end A (end portion) of the side wall portion 232 as a base end toward the central portion in the short side direction, and the upper support portion at the end where the inclined rise ends 233 are connected.

The lower support portion 234 includes a lower convex portion 234 a and a lower pressing portion 234 b.
(1) As shown in FIG. 9, the lower convex portion 234a is formed to extend in the direction from the lower end portion of the side wall portion 233a to the other side wall portion 233a. The lower convex portion 234 a has a shape that is convex in the Z direction covering the surface 221 a of the holding portion 220 to which the light emitting element substrate 210 is attached.
(2) The edge portion in the short side direction Y of the lower convex portion 234 a forms a lower pressing portion 234 b that presses the surface 221 a of the attachment 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(上端部)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 engaging portion 233 b of the upper support portion 233 and the lower pressing portion 234 b of the lower support portion 234 sandwich the tip portion (upper end portion) of the first side surface portion 222-1 of the holding portion 220 and the attachment portion 221 By doing this, the cover portion 230 is fixed to the holding portion 220.

(Instrument body 100)
Next, the configuration of the tool body 100 will be described. As shown in FIG. 4, the instrument body 100 includes a recess 111, inclined portions 114-1 and 114-2, and lids 120-1 and 120-2.
(1) The recess 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 mounting portion from the respective longitudinal sides of the opening 111a of the recess 111 and to spread.
(3) The lids 120-1 and 120-2 are disposed at both ends in the longitudinal direction, and cover the recess 111 and the inclined portions 114-1 and 114-2 at the end in the longitudinal direction X.
(4) The instrument body 100 includes the spring portion 130 and the terminal block 140. The spring portion 130 is disposed on the flat plate portion 112 and is coupled 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 instrument body 100 comprises a recess 111. As shown in FIG. 4, the concave portion 111 has a first side wall rising from the elongated flat portion 112 and one flat plate end 112 a and the other flat plate end 112 b along the longitudinal direction X of the flat plate 112. It has a concave shape having a portion 113-1 and a second side wall portion 113-2 and accommodates a part of the light source unit 200.

The flat portion 112 is provided with a spring portion 130 and a terminal block 140. Further, the flat plate portion 112 is formed with a power lead-in hole 112c for drawing in a power supply line for receiving power supply from a commercial power supply, and a fixing hole 112d for fixing to a mounting portion by a mounting material such as a bolt.

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 cross-sectional view of the cover for explaining the thickness change of the main portion 231. As shown in FIG. 11-13 is a figure for demonstrating the thickness change of the main part 231 in all.

(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 thinner than the central region 237. According to this configuration, the irradiation of the light emitted from the main portion 231 can be made to be close uniformly with a simple configuration in the short side direction Y of the main portion 231. The central region 237 is a region sandwiched by the two side regions 236 in the short direction Y of the convex cross-sectional shape 230D of the main portion 231.
Both side areas 236 are present on both sides of the central area 237. In the both side regions 236, the left side region 236 includes one end 231a, and the right side region 236 includes the other end 231b.
(2) FIG. 10 shows the structure of the thickness of the main portion 231, so that the irradiation of light emitted from the main portion 231 is made to approach uniformly with a simple configuration in the short direction Y of the main portion 231. It is sufficient that the light diffusion degree of both side regions 236 in the short direction Y including the one end portion 231 a and the other end portion 231 b is smaller than that of the central region 237 in the short direction Y. The adjustment of the diffusion degree is not limited to the thickness change of the main portion 231, or in addition to the thickness change, the diffusion degree may be adjusted by surface processing of the main portion 231 or the component configuration of the material constituting the main portion 231 .
(3) Also, 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, the light transmittance of the two side regions 236 may be larger than that of the central region 237. Also in the case of the transmittance, in addition to the thickness of the main portion 231, the degree of diffusion may be adjusted by surface processing of the main portion 231 or the component configuration of the material constituting the main portion 231. It is possible to improve the uniformity of the irradiation of the light in the short direction Y with a simple configuration by any one or any two or all of the diffusivity, the transmittance, and the thickness.

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 view for explaining a change in thickness of the main portion 231. As shown in FIG. FIG. 11 is a cross-sectional view corresponding to FIG. The "corresponding" is because in FIG. 8 it is a cross section in which the harness clamp 270 appears but in FIG. 11 it is a cross section in which the connection fitting 250 appears. The cover 230 has the same cross section.
(1) In FIG. 11, the main portion 231 is a cross-sectional view in which the curvature radius R2 of the outer surface 231-2 of the convex cross-sectional shape 230D is different from the curvature radius R1 of the inner surface 231-1 of the convex cross-sectional shape 230D. In the case of FIG. 11, the upper side (curvature radius R1) and the lower side (curvature radius 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. 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 the side regions 236.
(2) In the main portion 231 shown in FIG. 11, the curvature radius R2 of the outer surface 231-2 of the convex cross sectional shape 230D is smaller than the curvature radius 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 curvature center O (R2) of the outer surface 231-2 of the convex cross-sectional shape 230D is different from the curvature center 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 below the center of curvature O (R1) on the central axis 11. In the main part 231 of FIG. 11, the thickness of both side areas 236 is thinner than that of the central area 237, so that the irradiation of light emitted from the main part 231 can be made uniform in the lateral direction Y of the main part 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. As shown in FIG. FIG. 12 is the same cross-sectional view as FIG. Also in the case of FIG. 12, as in FIG. 11, the upper side (curvature radius R1) and the lower side (curvature radius R2) of the dashed dotted line sandwiched between one end 231a and the other end 231b are respectively The inner surface 231-1 of the main portion 231 forms an outer surface 231-2. 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 length as the radius of curvature R1 of the inner surface 231-1 of the convex cross-sectional shape 230D The curvature center O (R2) of the curvature radius R2 is below the curvature center O (R1) of the curvature radius R1 on the central axis 11. Even in the main portion 231 of FIG. 12, the thickness of both side regions 236 is thinner 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 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 still another view for explaining the thickness change of the main portion 231. As shown in FIG. 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 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-described convex cross-sectional shape 230D that is symmetrical in the left-right direction with the central axis 11 as the target axis when the short direction Y is the left-right direction. The light emitting element 212 intersects with 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 point 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. Thus, the thickness tk (k = 1, 2) at the points Lp1 and Lp2 of the inner surface 231-1 forming the distance Lk changes. In FIG. 13, assuming that the thickness at the point Lp1 at the distance L1 is t1, and the thickness at the point Lp2 at the distance L2 is t2, t1> t2. The thickness tk of the main portion 231 at the location Lpk (k = 1, 2,...) Forming the distance Lk is the thickness in the direction perpendicular to the tangent at the location 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 both side regions 236 is thinner than that of the central region 237, so that the irradiation of light emitted from the main portion 231 approaches uniform 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 meanings as in FIG. 13, and the description in 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 234)
In FIG. 9, a side wall portion 233 a located on the left side of the central axis 11 is an upper and lower wall shaped portion 2233 a formed at the end portion E of the rising of the inclined portion 232-1. The upper and lower wall shaped portion 2233a has a wall shaped upper side wall shaped portion 2233-1 extending in the opposite direction of the Z direction at the end portion E, and a wall shaped lower side wall shaped portion 2233-2 extending in the Z direction. Upper and lower wall-shaped portions 2233a 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. From the Z-direction end of the left lower side wall shape portion 2233-2 of the central axis 11, the lower side support portion 234 extending toward the lower side wall shape portion 2233-2 (the right side of the central axis 11) Part) is formed, and the right side of the central axis 11 is also the same. In the cover side wall portion 232, there is no member connected to the opposite surface facing the other 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 234 and the facing surface of the cover side wall 232 of the cover side wall 232. That is, there is no reverse extending portion extending in the direction of connection with the cover side wall portion 232, as indicated by the two-dot chain line, in the lower support portion 234.
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 can prevent that the clearance gap (FIG. 8) of the inclination part 232-1 and the instrument main body 100 becomes a dark part.

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):h2/h1≧0.340、かつ、h1<R、
と、
条件(2):h1/W≧0.245、かつ、h1<R、
との2つの条件(1)、条件(2)のうち、いずれかの条件が成立するものとする。
ここで、h1は図8に示す寸法であり、h2、Wは図9に示す寸法である。

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どうしの外側距離である。
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。
With h1 shown in FIG. 8 and h2, W, R shown in FIG. 9, the light source unit 200 can define dimensions as follows.
The convex cross-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.
A dimension h1 shown in FIG. 8 is a distance from an intersection point P of the light emitting surface 212S of the light emitting element 212 to 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 B of the cover side wall 232 and the end A of the rising end of the cover side wall 232 positioned in the opposite direction (opposite direction Z) to the end B. And the distance in the central axis 11 direction.
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 end portions A which are the respective end portions of the rising of the pair of cover side wall portions 232 in the short direction Y.
By satisfying one of the condition (1) and the condition (2), the irradiation of the upper side (the direction opposite to the Z direction) of the cover side wall portion 232 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 233 c (rib portion). The reflective rib 233c protrudes from the upper side wall shape portion 2233-1 in the longitudinal direction X in a direction opposite to the direction of the other upper side wall shape portion 2233-1.
By providing the reflection rib 233c in the cover portion 230 and reflecting the light emitted from the cover portion 230 by the reflection rib 233c, the gap between the cover portion 230 and the instrument main body 100 (FIG. 8) Can be reduced. Thus, the design of the lighting device 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 113-1 a are white. In addition, the pair of inclined portions 232-1, the pair of cover side wall portions 232, and the main portion 231 have light transparency and light diffusivity, and the pair of reflection ribs 233c and the inner side surfaces 113-2a and 113-1a have high reflection. It has a characteristic. In this embodiment, the reflective rib 233c is formed on both of the pair of upper side wall shaped portions 2233-1. However, the reflective rib 233c is formed on at least one of the pair of upper side wall shaped portions 2233-1. It may be done. The pair of inclined portions 232-1 may have high reflection characteristics as white. The reflective rib 233c is formed 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 is recessed in a concave shape toward the other cover side wall portion 232. That is, focusing on the cover side wall portion 232 on the left side of the central axis 11 in FIG. 8, the cover side wall portion 232 is directed toward the cover side wall portion 232 on the right side of the central axis 11 with the end A and the end B It has a concave shape.
As described above, the cover portion 230 has a shape in which the pair of cover side wall portions 232 is recessed toward the other cover side wall portion 232 in a concave shape. Therefore, when the operator grasps the concave shape, the workability when attaching the light source unit 200 to the instrument body 100 and the workability when removing the light source unit 200 from the instrument body 100 are improved.
The dimension regarding the concave shape of the cover side wall part 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,
It can be defined as h2, D, W and R2 are all the dimensions shown in FIG. As shown in FIG. 9, the dimension h2 is an end B of the cover side wall 232 and an end which is a rising end of the cover side wall 232 positioned in the opposite direction (anti-Z direction) to the end B A distance between A and the central axis 11 direction. 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 sidewall 232. Further, W is an outer distance between the end portions A which are the respective end portions of rising of the pair of cover side wall portions 232 in the short 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 instrument main body 100 and the workability when removing the light source unit 200 from the instrument main body 100. It is a size in consideration of the shape and size of the operator's finger grasping the concave shape.
Then, with regard to which one of the condition (4) and the condition (5) is selected, the attachment strength for attaching the light source unit 200 to the instrument body 100 is considered.
Furthermore, it is preferable that the cover side wall part 232 make the end A and the end B a curved surface shape smaller than R 2 to relieve the stress applied to the fingertip at the time of operation.

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 shape portion 2233a below the engaging portion 233b, so the cover portion 230 is attached to the holding portion 220 when the cover portion 230 is attached. It becomes more difficult for the holder 220 to fall off.
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, an angle θ2 between the rising direction of the inclined portion 232-1 and the lower side wall shape portion 2233-2 in the cross sections shown in FIGS. 8 and 9 is an acute angle (θ2 <90 °). For this reason, with the effect that the cover portion 230 is more difficult to come off from the holding portion 220, it is possible to reduce the possibility of breakage of the connection portion between the upper and lower wall shape portion 2233a and the inclined portion 232-1. Then, when the light source unit 200 is removed from the tool body 100, there is little possibility that the cover portion 230 may be detached from the holding portion 220 or the cover portion 230 may be damaged. The workability when removing 200 is improved.
In addition, the connection location of the upper side wall shape part 2233-1 and the termination | terminus part (end part A) of the inclination part 232-1 can select any one of right angle, an obtuse angle, and an acute angle in consideration of a moldability etc.

実施の形態1で述べた通り、カバー部230は、側壁部233aの上端部(終端部)から水平方向に伸びるように形成された係合部233bが、保持部220に形成された第二の側壁部222−2の上端部222−2a(保持係合部)と係合する。図26では図8の右側の上端部222−2aを示しているが、図8の左側も右側と同様に、左側の係合部233bが、保持部220に形成された第一の側壁部222−1の上端部222−1a(保持係合部)と係合する。このように、一対の係合部233bが、一対の保持係合部と係合することによって、カバー部230は、保持部220に取り付けられる。   As described in the first embodiment, the cover portion 230 is a second portion in which the engagement portion 233 b formed to extend in the horizontal direction from the upper end portion (end portion) of the side wall portion 233 a is formed in the holding portion 220. It engages with the upper end portion 222-2a (holding and engaging portion) of the side wall portion 222-2. Although the upper end 222-2a on the right side of FIG. 8 is shown in FIG. 26, the left side of FIG. 8 is the first side wall 222 in which the engaging part 233b on the left side is formed in the holding part 220 similarly to the right side. It engages with the upper end 222-1a (holding and engaging part) of -1. Thus, the cover 230 is attached to the holding portion 220 by engaging the pair of engaging portions 233b with the pair of holding and engaging portions.

実施の形態1では、図26に示すとおり、カバー部230の係合部233bと、第二の側壁部222−2の上端部222−2aとは、断面視において一点で接する。つまり、係合部233bと第二の側壁部222−2の上端部222−2aとは、長手方向に沿って、線接触で接する態様となっている。図26のように、第二の側壁部222−2の上端部222−2aは内側に折り返された曲げ加工(ヘミング加工とも称する。)が施されており、上端部222−2aの外側は長手方向に沿って曲面で形成されている。側壁部233aの上端部(終端部)から水平方向に伸びるように形成された係合部233bは、第二の側壁部222−2の上端部222−2aの外側表面222−2aaと対向する面が、第二の側壁部222−2の上端部222−2aの外側表面222−2aaとは異なる形状で形成されている。このため、係合部233bの内側表面233baと第二の側壁部222−2の上端部222−2aの外側表面222−2aaとは、長手方向に沿って面接触ではなく線接触で接する。   In the first embodiment, as shown in FIG. 26, the engaging portion 233b of the cover 230 and the upper end 222-2a of the second side wall 222-2 are in contact at one point in cross sectional view. That is, the engagement portion 233b and the upper end portion 222-2a of the second side wall portion 222-2 are in line contact with each other along the longitudinal direction. As shown in FIG. 26, the upper end 222-2a of the second side wall 222-2 is bent inward (also referred to as hemming), and the outside of the upper end 222-2a is elongated. It is formed by a curved surface along the direction. The engaging portion 233b formed to extend in the horizontal direction from the upper end (terminal end) of the side wall 233a is a surface facing the outer surface 222-2aa of the upper end 222-2a of the second side wall 222-2 However, the outer surface 222-2aa of the upper end portion 222-2a of the second side wall portion 222-2 is formed in a different shape. Therefore, the inner surface 233ba of the engaging portion 233b and the outer surface 222-2aa of the upper end portion 222-2a of the second side wall portion 222-2 are in line contact, not in surface contact, in the longitudinal direction.

カバー部230は、自重を支える強度を確保して保持部220に取り付けられていればよく、線接触で充分である。そして、係合部233bの内側表面233baを第二の側壁部222−2の上端部222−2aの外側表面222−2aaの形状に合わせた形状とする必要がなくなるため、カバー部230と保持部220との寸法管理の精度が緩和され、部品製造の歩留まりを上げ部品コストを下げることができる。また、光源ユニット200の製造工程において、カバー部230を保持部220に取り付ける際に、係合部233bに過度な応力を加えることなくスムーズに取り付け作業ができるので、カバー部230を変形させたり損傷させたりするおそれがなくなる。さらに、光源ユニット200の修繕工程において、カバー部230を保持部220から取り外す際に、係合部233bに過度な応力を加えることなくスムーズに取り外し作業ができるので、カバー部230を変形させたり損傷させたりするおそれがなくなる。   The cover portion 230 may be attached to the holding portion 220 while securing strength to support its own weight, and line contact is sufficient. Then, since the inner surface 233ba of the engaging portion 233b does not have to have a shape conforming to the shape of the outer surface 222-2aa of the upper end portion 222-2a of the second side wall portion 222-2, the cover portion 230 and the holding portion The accuracy of dimensional control with 220 can be relaxed, which can increase the yield of component manufacture and reduce the cost of components. Further, in the manufacturing process of the light source unit 200, when the cover 230 is attached to the holding part 220, the attachment can be smoothly performed without applying an excessive stress to the engaging part 233b, so the cover 230 is deformed or damaged There is no risk of Furthermore, in the repair process of the light source unit 200, when the cover 230 is removed from the holding part 220, the removal can be performed smoothly without applying excessive stress to the engaging part 233b, so the cover 230 is deformed or damaged. There is no risk of

ところで、保持部220を形成する材料とカバー部230を形成する材料とが異なる材料で形成される場合、相互の熱膨張率は異なるものとなる。実施の形態1では、係合部233bの内側表面と第二の側壁部222−2の上端部222−2aの外側表面とは、長手方向に沿って面接触ではなく線接触で接するようにした。よって、光源ユニット200を点灯させたり消灯させたりすることによって、カバー部230と保持部220との異なる伸縮(移動)に伴って接触部から発生する擦れ音、相互の接触状態が剪段することによって発生する衝撃音などの異音(きしみ音)を抑制できる効果も得られる。   By the way, when the material for forming the holding portion 220 and the material for forming the cover portion 230 are formed of different materials, the coefficients of thermal expansion are different from each other. In the first embodiment, the inner surface of the engagement portion 233b and the outer surface of the upper end portion 222-2a of the second side wall portion 222-2 are in contact in the longitudinal direction not in surface contact but in line contact. . Therefore, by turning on or off the light source unit 200, the rubbing noise generated from the contact portion along with the different expansion and contraction (movement) of the cover portion 230 and the holding portion 220, and the contact state with each other is sheared. The effect of suppressing abnormal noise (squeaking noise) such as shock noise generated by

なお、長手方向におけるカバー部230と保持部220との線接触は、係合部233bと上端部222−2a(保持係合部)との接触に限定されるものではなく、係合部233bおよび上端部222−2a(保持係合部)以外の、互いに対向するカバー部230と保持部220との対向面どうしが線接触で接するようにしてもよい。例えば、係合部233bを除く上側支持部233と上端部222−2aを除く第二の側壁部222−2とが線接触で接するようにしてもよいし、下側支持部234と取付面221aとが線接触で接するようにしてもよい。   The line contact between the cover portion 230 and the holding portion 220 in the longitudinal direction is not limited to the contact between the engaging portion 233 b and the upper end portion 222-2 a (holding engaging portion), and the engaging portion 233 b and The opposing surfaces of the cover portion 230 and the holding portion 220 facing each other other than the upper end portion 222-2a (holding and engaging portion) may be in line contact with each other. For example, the upper support portion 233 excluding the engaging portion 233b and the second side wall portion 222-2 excluding the upper end portion 222-2a may be in line contact with each other, or the lower support portion 234 and the attachment surface 221a. And may be in line contact.

実施の形態3.
図27〜図29を参照して、実施の形態3のカバー部3230(光源カバー)を説明する。
図27は、実施の形態3におけるカバー部3230の断面形状を示す。カバー部3230は、図6に示すカバー部230と断面形状が異なる。具体的には、断面形状のうち、図27のC部の形状が異なる。カバー部3230はカバー部230と同様に、図6に示す保持部220に取り付けることができる。
Third Embodiment
With reference to FIGS. 27-29, the cover part 3230 (light source cover) of Embodiment 3 is demonstrated.
FIG. 27 shows the cross-sectional shape of the cover portion 3230 in the third embodiment. The cover 3230 has a cross-sectional shape different from that of the cover 230 shown in FIG. Specifically, in the cross-sectional shape, the shape of the portion C in FIG. 27 is different. The cover portion 3230 can be attached to the holding portion 220 shown in FIG.

カバー部3230は、実施の形態1で述べたカバー部230に対して断面形状が異なる光源カバーであるので、カバー部3230に対しては、実施の形態1で述べた内容、実施の形態2で述べた内容及び図26を用いて説明した実施の形態1の補正説明の内容等を、反映することができる。   Since the cover 3230 is a light source cover having a cross-sectional shape different from that of the cover 230 described in the first embodiment, the contents described in the first embodiment and the second embodiment can be applied to the cover 3230. It is possible to reflect the contents described and the contents of the correction of the first embodiment described with reference to FIG.

図28は、図27の右側のB部の拡大図である。図28を参照して、カバー部3230の断面形状を説明するが、右側B部の説明は同様に左側B部にも当てはまる。   FIG. 28 is an enlarged view of a portion B on the right side of FIG. Although the cross-sectional shape of the cover portion 3230 will be described with reference to FIG. 28, the description of the right side B portion also applies to the left side B portion.

図28に示すように、カバー部3230は、上側支持部3231、下側支持部3232と、カバー側壁部3233、円弧部3234を備える。上側支持部3231は、第二の側面部222−2に取り付けられる取付部である。下側支持部3232は、上側支持部3231の下方から内側に突出する突出部である。円弧部3234は、図27に示すように円弧状に形成される。カバー側壁部3233は、円弧部3234の端部3231bから上側支持部3231に向かって立ち上がる。   As shown in FIG. 28, the cover 3230 includes an upper support 3231, a lower support 3232, a cover side wall 3233, and an arc 3234. The upper support portion 3231 is an attachment portion attached to the second side surface portion 222-2. The lower support portion 3232 is a projecting portion that protrudes inward from the lower side of the upper support portion 3231. The arc portion 3234 is formed in an arc shape as shown in FIG. The cover side wall portion 3233 rises from the end 3231 b of the arc portion 3234 toward the upper support portion 3231.

カバー側壁部3233は、凸部3233a、第一の曲部3233b、凹部3233c、第二の曲部3233dを有する。凸部3233aは、上側支持部3231から側方に突出する。第一の曲部3233bは、凸部3233aから外表面、内表面とも曲面(R形状)に形成される。凹部3233cは、第一の曲部3233bから凸部3233aが突出する側方とは逆方向(Y1方向)へ凹状に凹む。第二の曲部3233dは、凹部3233cと円弧部3234とを結合し、外表面、内表面とも曲面(R形状)に形成される。   The cover side wall portion 3233 has a convex portion 3233 a, a first curved portion 3233 b, a concave portion 3233 c, and a second curved portion 3233 d. The convex portion 3233 a protrudes laterally from the upper support portion 3231. The first curved portion 3233 b is formed in a curved surface (R shape) from the convex portion 3233 a to the outer surface and the inner surface. The concave portion 3233 c is concavely recessed in the direction (Y1 direction) opposite to the side where the convex portion 3233 a protrudes from the first curved portion 3233 b. The second curved portion 3233d couples the concave portion 3233c and the arc portion 3234, and both the outer surface and the inner surface are formed in a curved surface (R shape).

図28に示すように、透光性を有するカバー部3230(光源カバー)は、円弧部3234と、一対のカバー側壁部3233とを備える。円弧部3234は、図6のカバー部230と同様に長手形状をなし、図28のように、長手方向X(図6)を法線方向とする断面の断面形状が凸となる円弧形状をなす。一対のカバー側壁部3233は、円弧部3234の長手方向Xに沿い、円弧部3234の幅方向となる短手方向Yにおける円弧部3234の両側端部となる一方の端部3231a(図27)と他方の端部3231b(図27、図28)とを基端部として凸となるZ方向と反対方向にそれぞれ立ち上がる。カバー部3230では、一対のカバー側壁部3233のうちの少なくとも一方は、外表面に、他方のカバー側壁部3233に向かって凹形状に凹む凹形状部3233ca(図28のA,B,C,D)が形成されている。凹形状部3233caは、他方のカバー側壁部3233に向かう方向Y1において凹形状の底となると共に平面をなす底平面3233c−3(B,C)を有する。凹形状部3233caが形成されたカバー側壁部3233は、他方のカバー側壁部3233に向かう方向Y1における底平面3233c−3の裏側面となる内表面3233c−1が、他方のカバー側壁部に向かうY1方向に凸となる凸形状をなす。   As shown in FIG. 28, the translucent cover portion 3230 (light source cover) includes an arc portion 3234 and a pair of cover side wall portions 3233. The arc portion 3234 has a longitudinal shape similar to the cover portion 230 of FIG. 6, and as shown in FIG. 28, has an arc shape in which the cross-sectional shape of the cross section having the longitudinal direction X (FIG. 6) as the normal direction is convex. . The pair of cover side wall portions 3233 extends along the longitudinal direction X of the arc portion 3234, and one end portion 3231a (FIG. 27) which is both end portions of the arc portion 3234 in the width direction Y which is the width direction of the arc portion 3234 The other end 3231 b (FIGS. 27 and 28) is raised as a base end in the direction opposite to the Z direction which is convex. In the cover portion 3230, at least one of the pair of cover side wall portions 3233 has a concave shape portion 3233ca concaved toward the other cover side wall portion 3233 on the outer surface (A, B, C, D in FIG. ) Is formed. The recessed portion 3233 ca has a bottom flat surface 3233 c-3 (B, C) which is a bottom of the recessed shape and is flat in the direction Y <b> 1 directed to the other cover side wall portion 3233. In the cover side wall portion 3233 in which the concave portion 3233ca is formed, the inner surface 3233c-1 serving as the back surface of the bottom flat surface 3233c-3 in the direction Y1 toward the other cover side wall portion 3233 is Y1 toward the other cover side wall portion It has a convex shape that is convex in the direction.

凹形状部3233caは、底平面3233c−3と、上側斜面3233c−4と、下側斜面3233c−5とを有する。上側斜面3233c−4は、一対のカバー側壁部3233の立ち上がる方向(Z方向の反対方向)を上方向とし反対方向(Z方向)を下方向とした場合に底平面3233c−3の上方向において斜面をなす。下側斜面3233c−5は、底平面3233c−3の下方向において斜面をなす。   The concave portion 3233 ca has a bottom flat surface 3233 c-3, an upper slope 3233 c-4, and a lower slope 3233 c-5. The upper slope 3233 c-4 is sloped in the upper direction of the bottom plane 3233 c-3 when the rising direction of the pair of cover side wall portions 3233 (opposite to the Z direction) is upward and the opposite direction (Z direction) is downward. I The lower side slope 3233 c-5 forms a slope in the lower direction of the bottom plane 3233 c-3.

図28は、凹形状部3233caにおいて、上側斜面3233c−4と下側斜面3233c−5との両方が曲面3233eの場合を示している。また、凹部3233cは、内表面3233c−1が曲面に形成され、内表面3233c−1の曲面の頂部3233c−2に対向する外表面が平面(底平面3233c−3)として形成されている。さらに、凹部3233cの外表面は、底平面3233c−3から第一の曲部3233b及び第二の曲部3233dに向かって、曲面3233eが形成されている。   FIG. 28 illustrates the case where both the upper slope 3233 c-4 and the lower slope 3233 c-5 are curved surfaces 3233 e in the concave portion 3233 ca. Further, the concave portion 3233c is formed such that the inner surface 3233c-1 is a curved surface, and the outer surface opposite to the top portion 3233c-2 of the curved surface of the inner surface 3233c-1 is formed as a flat surface (bottom flat surface 3233c-3). Furthermore, on the outer surface of the recess 3233c, a curved surface 3233e is formed from the bottom flat surface 3233c-3 toward the first curved portion 3233b and the second curved portion 3233d.

このように、凹部3233cの内表面3233c−1の頂部3233c−2に対向する外表面が平面(底平面3233c−3)で形成されることによって、内表面3233c−1の頂部3233c−2近傍のカバー部3230の肉厚を厚くすることができる。   Thus, by forming the outer surface facing the top portion 3233c-2 of the inner surface 3233c-1 of the recess 3233c with a flat surface (bottom flat surface 3233c-3), the vicinity of the top portion 3233c-2 of the inner surface 3233c-1 The thickness of the cover 3230 can be increased.

よって、光源ユニットを器具本体から外す際には、カバー部3230の両側の凹部3233cをユーザーが指で挟んで外すが、凹部3233cの外表面に平面(底平面3233c−3)を形成することによって、カバー部3230の肉厚が厚くなる。よって、凹部3233cの変形量が抑制され、カバー部3230の強度を増すことができる。   Therefore, when removing the light source unit from the instrument main body, the user pinches and removes the concave portions 3233c on both sides of the cover portion 3230 with a finger, but by forming a flat surface (bottom flat surface 3233c-3) on the outer surface of the concave portion 3233c. The thickness of the cover 3230 is increased. Thus, the amount of deformation of the recess 3233 c is suppressed, and the strength of the cover 3230 can be increased.

また、凹部3233cの両端側に形成される第一の曲部3233b、第二の曲部3233d、特に第一、第二の曲部の内表面も曲面を形成するようにしている。このため、カバー部3230の両側の凹部3233cをユーザーが指でつかんだ際、凹部3233cと凸部3233aとの間、及び凹部3233cと円弧部3234との間にかかる応力を分散することができ、カバー部3230の強度を増すことができる。特に,凹部3233cと凸部3233aとの間及び凹部3233cと円弧部3234との間の連結部分(内表面)が角状に形成されている場合、この角状に形成されている部分に応力が集中する恐れがあるが、連結部分を曲面、特に内表面を曲面に形成することによって、応力の集中を解消することができる。   Further, the first curved portion 3233b and the second curved portion 3233d formed on both ends of the concave portion 3233c, in particular, the inner surfaces of the first and second curved portions also form a curved surface. Therefore, when the user holds concave portions 3233c on both sides of cover portion 3230 with a finger, stress applied between concave portion 3233c and convex portion 3233a and between concave portion 3233c and arc portion 3234 can be dispersed. The strength of the cover 3230 can be increased. In particular, when the connection portion (inner surface) between the recess 3233 c and the protrusion 3233 a and between the recess 3233 c and the arc 3234 is formed in a square shape, stress is generated in the portion formed in the square shape. Although there is a risk of concentration, stress concentration can be eliminated by forming the connecting portion as a curved surface, in particular, the inner surface as a curved surface.

なお、図29は、凹形状部3233caにおいて、上側斜面3233c−4と、下側斜面3233c−5とが、平面3233fである点が図28と異なる形状である。図29に示すように、凹部3233cの外表面を複数の平面(底平面3233c−3、上側斜面3233c−4である平面3233f、下側斜面3233c−4である平面3233f)で形成しても、本実施の形態の作用効果を得ることができる。   FIG. 29 is different from FIG. 28 in that the upper slope 3233 c-4 and the lower slope 3233 c-5 in the concave portion 3233 ca are flat surfaces 3233 f. As shown in FIG. 29, even if the outer surface of the recess 3233c is formed by a plurality of planes (bottom plane 3233c-3, plane 3233f which is the upper slope 3233c-4, plane 3233f which is the lower slope 3233c-4), The action and effect of the present embodiment can be obtained.

従来、発光素子および電源装置を内蔵する長尺状の光源ユニットであって、器具本体に着脱自在に取り付けられる光源ユニットがある。従来このような光源ユニットには、光源ユニットのカバーの表面が曲面である場合に光源ユニットが器具本体から外しにくいという課題があった。しかし、実施の形態1から実施の形態3に記載したカバー部によれば、光源ユニットを器具本体から外しやすくすることができ、さらに、光源カバー(カバー部)を光源ユニットから外れにくくすることができる。   Conventionally, there is a light source unit which is a long light source unit containing a light emitting element and a power supply device, and which is detachably attached to an instrument body.
