側板12は、発光ユニット取付凹部111の両端を覆うように取付部材11に取り付けられる。図5(B)に示すように、第1側板12aは、発光ユニット取付凹部111の一端を覆うように取付部材11に取り付けられる。第2側板12bは、発光ユニット取付凹部111の他端を覆うように取付部材11に取り付けられる。
ここで、「発光ユニット取付凹部111」とは、第1側縁部112a及び第2側縁部112b、並びに第1側板12a及び第2側板12bで囲まれる空間を示す。また、取付部材11に第1側板12a及び第2側板12bを取り付けることにより、開口が形成される。
The side plate 12 is attached to the attachment member 11 so as to cover both ends of the light emitting unit attachment recess 111. As shown in FIG. 5B, the first side plate 12 a is attached to the attachment member 11 so as to cover one end of the light emitting unit attachment recess 111. The second side plate 12b is attached to the attachment member 11 so as to cover the other end of the light emitting unit attachment recess 111.
Here, the “light emitting unit mounting recess 111” indicates a space surrounded by the first side edge 112a and the second side edge 112b, and the first side plate 12a and the second side plate 12b. Moreover, an opening is formed by attaching the first side plate 12 a and the second side plate 12 b to the attachment member 11.

図6(A)及び図6(B)に示すように、器具本体10は、発光ユニット20の取り付け位置を規制する位置規制部材113を備えていてもよい。位置規制部材113は、発光ユニット取付凹部111に配置される。位置規制部材113は、発光ユニット20が器具本体10に取り付けられた際に発光ユニット20と接触する。これにより、発光ユニット20は、発光ユニット取付凹部111内の所定の位置に位置決めされる。   As shown in FIGS. 6A and 6B, the instrument body 10 may include a position regulating member 113 that regulates the mounting position of the light emitting unit 20. The position regulating member 113 is disposed in the light emitting unit mounting recess 111. The position regulating member 113 comes into contact with the light emitting unit 20 when the light emitting unit 20 is attached to the instrument body 10. Thereby, the light emitting unit 20 is positioned at a predetermined position in the light emitting unit mounting recess 111.

例えば図6(A)に示すように、位置規制部材113は、発光ユニット取付凹部111の内壁から発光ユニット取付凹部111内に突出して設けられていてもよい。このとき、位置規制部材113は、発光ユニット取付凹部111の内壁に固定された金属材料等からなり、発光ユニット取付凹部111とは別部材で形成されている。また、位置規制部材113は、発光ユニット取付凹部111及び側縁部112と一体に形成されるように取付部材11の合板を曲げ加工して形成してもよい。具体的には、発光ユニット取付凹部111の内壁の一部に切込みを形成し、その切込みが発光ユニット取付凹部111内に突出するように合板を折曲げることにより、例えば断面コ字状又は断面U字状の突出部である位置規制部材113を形成することができる。   For example, as shown in FIG. 6A, the position regulating member 113 may be provided so as to protrude from the inner wall of the light emitting unit mounting recess 111 into the light emitting unit mounting recess 111. At this time, the position restricting member 113 is made of a metal material or the like fixed to the inner wall of the light emitting unit mounting recess 111, and is formed as a separate member from the light emitting unit mounting recess 111. Further, the position regulating member 113 may be formed by bending a plywood of the mounting member 11 so as to be formed integrally with the light emitting unit mounting recess 111 and the side edge portion 112. Specifically, by forming a cut in a part of the inner wall of the light emitting unit mounting recess 111 and bending the plywood so that the cut protrudes into the light emitting unit mounting recess 111, for example, a U-shaped section or a U section A position restricting member 113 that is a letter-shaped protrusion can be formed.

また、例えば図6(B)に示すように、位置規制部材113は、発光ユニット取付凹部111の側板12に配置されていてもよい。このとき、位置規制部材113は、発光ユニット取付凹部111の側板12に突出して設けられる。具体的には、器具本体10に発光ユニット20を取り付けた際に発光ユニット20と対向する対向領域(図6(B)において点線で示す領域)において、側板12の一部を発光ユニット取付凹部111に向かって折り曲げることにより、位置規制部材113が形成される。   For example, as illustrated in FIG. 6B, the position regulating member 113 may be disposed on the side plate 12 of the light emitting unit mounting recess 111. At this time, the position restricting member 113 is provided so as to protrude from the side plate 12 of the light emitting unit mounting recess 111. Specifically, when the light emitting unit 20 is attached to the instrument main body 10, a part of the side plate 12 is partly disposed on the light emitting unit mounting recess 111 in a facing region (region indicated by a dotted line in FIG. 6B) facing the light emitting unit 20. The position restricting member 113 is formed by bending toward the front.

図5(B)に示すように、バネ部13は、例えば取付部材11の底板部114に固定される。バネ部13は、後述する発光ユニット20のバネ受部27と係合することにより発光ユニット20を器具本体10の発光ユニット取付凹部111に取り付けた状態を維持することに利用される。具体的には、第1バネ部13aは発光ユニット20の第1バネ受部27aと係合し、第2バネ部13bは発光ユニット20の第2バネ受部27bと係合する。すなわち、第1バネ受部27a及び第2バネ受部27b並びに第1バネ部13a及び第2バネ部13bは、発光ユニット取付凹部111に発光ユニット20を取り付けた状態を維持する取付状態維持部として機能する。   As shown in FIG. 5B, the spring portion 13 is fixed to the bottom plate portion 114 of the mounting member 11, for example. The spring portion 13 is used to maintain a state in which the light emitting unit 20 is attached to the light emitting unit mounting recess 111 of the instrument body 10 by engaging with a spring receiving portion 27 of the light emitting unit 20 described later. Specifically, the first spring portion 13 a is engaged with the first spring receiving portion 27 a of the light emitting unit 20, and the second spring portion 13 b is engaged with the second spring receiving portion 27 b of the light emitting unit 20. In other words, the first spring receiving portion 27a and the second spring receiving portion 27b, and the first spring portion 13a and the second spring portion 13b serve as an attachment state maintaining portion that maintains the state where the light emitting unit 20 is attached to the light emitting unit attaching recess 111. Function.

端子台14には、後述する電力供給ケーブルが接続される。具体的には、端子台14には、天井又は壁等の被取付面から導出されて後述する電源部28との間を電気的に接続する電力供給ケーブルが接続される。端子台14は、例えばネジ等により取付部材11に取り付けられる。
吊りボルト用孔部15は、図示しない吊りボルトにより、天井又は壁等の被取付面に器具本体10を取り付けるために設けられる。
電力供給ケーブル用孔部16は、天井又は壁等の被取付面から導出された電力供給ケーブル40を器具本体10の発光ユニット取付凹部111内に引き込むために設けられる。
A power supply cable described later is connected to the terminal block 14. Specifically, the terminal block 14 is connected to a power supply cable that is led out from a mounting surface such as a ceiling or a wall and electrically connects to a power supply unit 28 described later. The terminal block 14 is attached to the attachment member 11 with screws or the like, for example.
The suspension bolt hole 15 is provided to attach the instrument main body 10 to a surface to be attached such as a ceiling or a wall with a suspension bolt (not shown).
The power supply cable hole 16 is provided to draw the power supply cable 40 led out from the mounting surface such as the ceiling or wall into the light emitting unit mounting recess 111 of the instrument body 10.

[Light emitting unit]
Hereinafter, the configuration of the light emitting unit 20 will be described.
FIG. 7 is a perspective view showing the external appearance of the light emitting unit 20 from above.
FIG. 8 is a cross-sectional view showing the AA ′ cross section of the light emitting unit 20 shown in FIG.
FIG. 9 is an exploded perspective view showing the configuration of the light emitting unit 20.
As shown in FIGS. 7, 8, and 9, the light emitting unit 20 includes a light emitting element 21, a translucent cover 22 (a main cover portion 221, a first end cover 222, a second end cover 223), and a substrate group. 23, a support member 24, a board fixing member 25 (25a to 25n), a screw 26, a spring receiving portion 27 (27a and 27b), a power source portion 28, and a reflecting member 29 (first reflecting component 29a, first 2 reflective component 29b and 3rd reflective component 29c). In FIG. 9, only the screws 26 for fixing the substrate fixing member 25a are denoted by reference numerals, and the screws for fixing the substrate fixing members 25n to the substrate fixing members 25b are omitted.

以下、発光ユニット20の各部について詳細に説明する。
(透光性カバー)
透光性カバー22は、発光素子21を覆い、発光ユニット20を器具本体10に取り付けた際に器具本体10に入り込む形状を有している。透光性カバー22は、発光素子21から照射された光を拡散する機能を有している。
図9に示すように、透光性カバー22は、発光素子21を覆う主カバー部221と、第1エンドカバー222及び第2エンドカバー223とを備える。第1エンドカバー222は、主カバー部221の一端を覆うように取り付けられる。第2エンドカバー223も同様に、主カバー部221の他端を覆うように取り付けられる。
Hereinafter, each part of the light emitting unit 20 will be described in detail.
(Translucent cover)
The translucent cover 22 covers the light emitting element 21 and has a shape that enters the instrument body 10 when the light emitting unit 20 is attached to the instrument body 10. The translucent cover 22 has a function of diffusing light emitted from the light emitting element 21.
As shown in FIG. 9, the translucent cover 22 includes a main cover portion 221 that covers the light emitting element 21, a first end cover 222, and a second end cover 223. The first end cover 222 is attached so as to cover one end of the main cover portion 221. Similarly, the second end cover 223 is attached so as to cover the other end of the main cover portion 221.

図4に示すように、発光ユニット20は、透光性カバー22の一部が器具本体10の開口に入り込むようにして取り付けられる。このとき、発光ユニット20は、透光性カバー22の一部が器具本体10の発光ユニット取付凹部111の内壁面に接触した状態で発光ユニット取付凹部111に取り付けられる。
これにより、発光ユニット20がたわんだ場合であっても照明装置の外観不良が生じにくくなる。これは、発光ユニット20がたわんだ場合に発光ユニット取付凹部111に入り込んでいた透光性カバー22が露出するのみであり、器具本体10と発光ユニット20との間に隙間が生じなくなるためである。
As shown in FIG. 4, the light emitting unit 20 is attached such that a part of the translucent cover 22 enters the opening of the instrument body 10. At this time, the light emitting unit 20 is attached to the light emitting unit mounting recess 111 in a state where a part of the translucent cover 22 is in contact with the inner wall surface of the light emitting unit mounting recess 111 of the instrument body 10.
Thereby, even if it is a case where the light emission unit 20 bends, it becomes difficult to produce the appearance defect of an illuminating device. This is because, when the light emitting unit 20 is bent, only the translucent cover 22 that has entered the light emitting unit mounting recess 111 is exposed, and no gap is generated between the instrument body 10 and the light emitting unit 20. .

図10は、主カバー部221と支持部材24及び第1エンドカバー222と支持部材24のそれぞれの係合部を詳細に説明する分解斜視図である。図10(A)及び図10(B)は、主カバー部221と、第1エンドカバー222と、支持部材24との係合状態を説明するための図である。

また、主カバー部221の内壁面には、突出部221c及び221dが形成されている。突出部221c及び221dのそれぞれは、支持部材24を保持している。
FIG. 10 is an exploded perspective view illustrating in detail the engaging portions of the main cover portion 221 and the support member 24 and the first end cover 222 and the support member 24. FIGS. 10A and 10B are views for explaining the engagement state of the main cover portion 221, the first end cover 222, and the support member 24.
FIG. 11 is an orthographic view showing the configuration of the first end cover 222 and the second end cover 223.
As shown in FIGS. 10A and 10B, the main cover portion 221 includes fixing hole portions 221 a and 221 b which are first fixing hole portions for fixing the main cover portion 221 to the support member 24. (221b is not shown). The bottom surface of the main cover part 221 is formed in a flat shape. The fixing holes 221a and 221b are provided in a region facing the support member 24 of the main cover 221. The fixing holes 221a and 221b are formed in, for example, an oval shape. The main cover 221 has the same shape as the fixing holes 221a and 221b at the other end on the side where the first end cover 222 facing the one end provided with the fixing holes 221a and 221b is attached. It has a fixing hole.
In addition, projecting portions 221 c and 221 d are formed on the inner wall surface of the main cover portion 221. Each of the protrusions 221c and 221d holds the support member 24.

第1エンドカバー222は、支持部材24に係合される第1係合部を有している。第1エンドカバー222の第1係合部は、支持部材24の端部側に形成された第1被係合部(詳細は後述する)を係止可能に形成される。
支持部材24に係合される第1係合部は、例えば以下のような構成とすることができる。
図10(A)及び図10(B)、並びに図11に示すように、第1エンドカバー222は、第1係合部として孔部222a及び222bを有する。孔部222a及び222bには、支持部材24に設けられた第1被係合部である突出部24g及び24hがそれぞれ係止される。
The first end cover 222 has a first engagement portion that is engaged with the support member 24. The first engaging portion of the first end cover 222 is formed to be able to lock a first engaged portion (details will be described later) formed on the end portion side of the support member 24.
The 1st engaging part engaged with the support member 24 can be set as the following structures, for example.
As shown in FIGS. 10A and 10B and FIG. 11, the first end cover 222 has holes 222a and 222b as first engaging portions. Projecting portions 24g and 24h, which are first engaged portions provided on the support member 24, are locked in the holes 222a and 222b, respectively.

また、第1エンドカバー222は、第1係合部として上述した孔部222a及び222bの代わりに突出部(図示せず)を有していてもよい。この場合、支持部材24には、第1被係合部として孔部を設け(図示せず)、第1エンドカバー222に設けられた突出部は、支持部材24の孔部に係止可能に形成される。   Moreover, the 1st end cover 222 may have a protrusion part (not shown) instead of the hole parts 222a and 222b mentioned above as a 1st engaging part. In this case, the support member 24 is provided with a hole (not shown) as the first engaged portion, and the protrusion provided on the first end cover 222 can be locked to the hole of the support member 24. It is formed.

さらに、第1エンドカバー222は、第1係合部(孔部222a及び222b)とは別に、第2係合部を有している。第2係合部は、支持部材24に形成された第2被係合部(詳細は後述する)を係止可能に形成される。第1エンドカバー222は、第2係合部として、例えば突出部222c及び222dを有している。突出部222c及び222dは、支持部材24に設けられた第2係合部である係合用孔部24i及び24jにそれぞれ係止される。   Further, the first end cover 222 has a second engaging portion separately from the first engaging portions (holes 222a and 222b). The second engaging portion is formed to be able to lock a second engaged portion (details will be described later) formed on the support member 24. The first end cover 222 has, for example, protrusions 222c and 222d as the second engaging portion. The protrusions 222c and 222d are engaged with engagement holes 24i and 24j, which are second engagement parts provided on the support member 24, respectively.

また、第2エンドカバー223は、第1エンドカバー222と同様に、第1係合部、第2係合部を有している。   Similarly to the first end cover 222, the second end cover 223 has a first engagement portion and a second engagement portion.

(発光素子基板)
図12は、基板群23の構成を示す平面図である。
図12に示すように、発光素子基板231及び232は、一方向に長く延びた長尺形状の板状部材であり、一方の面に複数の発光素子21が実装される。図12に示すように、長尺形状の複数の発光素子基板が、互いの短辺同士が対向する状態で発光素子基板の長手方向に列状に並べられて基板群23を構成する。基板群23は、例えば、2枚の発光素子基板231及び232で形成される。以下、基板群23は、2枚の発光素子基板231及び232で形成されるものとして説明する。
(Light emitting element substrate)
FIG. 12 is a plan view showing the configuration of the substrate group 23.
As shown in FIG. 12, the light emitting element substrates 231 and 232 are long plate-like members extending in one direction, and a plurality of light emitting elements 21 are mounted on one surface. As shown in FIG. 12, a plurality of elongate light emitting element substrates are arranged in a row in the longitudinal direction of the light emitting element substrates in a state where their short sides are opposed to each other, thereby constituting a substrate group 23. The substrate group 23 is formed of, for example, two light emitting element substrates 231 and 232. Hereinafter, the substrate group 23 will be described as being formed of two light emitting element substrates 231 and 232.

図12に示すように、発光素子基板231及び232には、発光素子21に電力を供給するための配線28dがそれぞれ接続される。このとき、発光素子基板231及び232は、後述する支持部材24の基板支持面24aに設けられた貫通部24dを通る配線28dにより電源部28と接続される。電源部28の電源回路から供給された電力は、配線28dを介して発光素子21に供給される。
なお、図12に示す配線23cは、発光素子基板231及び232を電気的に接続するための配線である。
As shown in FIG. 12, wirings 28 d for supplying power to the light emitting element 21 are connected to the light emitting element substrates 231 and 232, respectively. At this time, the light emitting element substrates 231 and 232 are connected to the power supply unit 28 by a wiring 28d passing through a through portion 24d provided on a substrate support surface 24a of the support member 24 described later. The electric power supplied from the power supply circuit of the power supply unit 28 is supplied to the light emitting element 21 through the wiring 28d.
Note that the wiring 23 c illustrated in FIG. 12 is a wiring for electrically connecting the light emitting element substrates 231 and 232.

基板群23上には、電源部28から導出される配線28dが接続される電源接続用端子群(コネクタ231a及び232a)と、隣り合う発光素子基板231及び232間を接続する配線23cが接続される基板接続用端子群(コネクタ231b及び232b)とが設けられる。電源接続用端子群及び基板接続用端子群は、発光素子基板231及び232の対向する短辺側の端部にそれぞれ配置される。
すなわち、発光素子基板231の一方の短辺側の端部には、第1電源接続用端子であるコネクタ231aと、第1基板接続用端子であるコネクタ231bとが設けられている。また、発光素子基板232の一方の短辺側の端部には、第2電源接続用端子であるコネクタ232aと、第2基板接続用端子であるコネクタ232bとが設けられている。そして、発光素子基板231のコネクタ231a及びコネクタ231bが設けられた側の短辺と、発光素子基板232のコネクタ232a及びコネクタ232bが設けられた側の短辺とが対向配置されることにより、基板群23が形成される。なお、発光素子基板231及び232は、互いに同一の構成を有していてもよい。
On the substrate group 23, a power connection terminal group (connectors 231a and 232a) to which a wiring 28d led out from the power supply unit 28 is connected and a wiring 23c for connecting between the adjacent light emitting element substrates 231 and 232 are connected. Board connection terminal groups (connectors 231b and 232b). The power supply connection terminal group and the substrate connection terminal group are respectively disposed at the opposing short-side ends of the light emitting element substrates 231 and 232.
That is, a connector 231a that is a first power supply connection terminal and a connector 231b that is a first substrate connection terminal are provided at one short side end of the light emitting element substrate 231. In addition, a connector 232a which is a second power supply connection terminal and a connector 232b which is a second substrate connection terminal are provided at one short side end of the light emitting element substrate 232. Then, the short side of the light emitting element substrate 231 where the connector 231a and the connector 231b are provided and the short side of the light emitting element substrate 232 where the connector 232a and the connector 232b are provided are opposed to each other. A group 23 is formed. Note that the light emitting element substrates 231 and 232 may have the same configuration.

ここで、コネクタ231a及びコネクタ232aの一方はプラス側端子であり、他方はマイナス側端子である。コネクタ231b及びコネクタ232bは、配線23cによって接続されている。
このため、基板群23において、発光素子基板231上に設けられた複数の発光素子21及び発光素子基板232上に設けられた複数の発光素子21の全てがコネクタ231aと、コネクタ232aとの間で直列に接続される。
このような構成とすることにより、基板群23の組み立て工程が容易になる。また、このような構成とすることにより、発光素子基板231及び232同士を接続する配線23c及び電源部28からの配線28dの引きまわし距離を短くすることができる。このため、ノイズの発生を抑制することができる。
Here, one of the connector 231a and the connector 232a is a plus side terminal, and the other is a minus side terminal. The connector 231b and the connector 232b are connected by the wiring 23c.
Therefore, in the substrate group 23, all of the plurality of light emitting elements 21 provided on the light emitting element substrate 231 and the plurality of light emitting elements 21 provided on the light emitting element substrate 232 are between the connector 231a and the connector 232a. Connected in series.
With such a configuration, the assembly process of the substrate group 23 is facilitated. Further, with such a configuration, it is possible to shorten the distance between the wiring 23c that connects the light emitting element substrates 231 and 232 and the wiring 28d from the power supply unit 28. For this reason, generation | occurrence | production of noise can be suppressed.

また、電源接続用端子群(コネクタ231a及び232a)は、基板群23の一方の長辺に沿って配置され、基板接続用端子群(コネクタ231b及び232b)は、基板群23の他方の長辺に沿って配置される。
このとき、コネクタ231a及び232aは、基板群23上において少なくとも1個の発光素子21を介して配置されることが好ましい。また、コネクタ231b及び232bは、少なくとも1個の発光素子21を介して配置されることが好ましい。これは、コネクタ231a及び232a、並びにコネクタ231b及び232bのそれぞれの間の沿面距離を確保するためである。
The power supply terminal groups (connectors 231a and 232a) are arranged along one long side of the board group 23, and the board connection terminal group (connectors 231b and 232b) is the other long side of the board group 23. It is arranged along.
At this time, the connectors 231a and 232a are preferably arranged on the substrate group 23 via at least one light emitting element 21. The connectors 231b and 232b are preferably disposed via at least one light emitting element 21. This is to ensure the creepage distance between the connectors 231a and 232a and the connectors 231b and 232b.

なお、図12に示すように、コネクタ231a及び231bは、発光素子基板231の短辺に最も近い位置に設けられた発光素子21と、短辺に2番目に近い位置に設けられた発光素子21との間の領域Xに設けられることが好ましい。また、コネクタ231a及び231bは、上述した領域Xのうち、短辺に2番目に近い位置に設けられた発光素子21よりも、短辺に最も近い位置に設けられた発光素子21に近い位置に設けられることが好ましい。

Moreover, it is preferable that the top part of the convex part 24 c has a shape that does not enter the ½ beam angle region of the light emitting element 21.

図14は、図12のB−B’断面を示す斜視断面図である。図12及び図14に示すように、支持部材24は、電源部28から導出される配線28dを通すための貫通部24dを備える。貫通部24dは、基板支持面24a上に設けられる。
ここで、図7に示すように、支持部材24は、支持部材24の長尺方向の両端に基板群23を固定するための第1の基板固定部及び第2の基板固定部を有している。第1の基板固定部及び第2の基板固定部は、例えば支持部材24の長尺方向の両端において電源部支持面24bに突出した基板固定部材25を固定するためのネジ26等を取り付けるネジ穴等の位置を示す。
貫通部24dは、第1の基板固定部と第2の基板固定部との間に設けられることが好ましい。これにより、貫通部24dを通して電源部支持面24bから基板支持面24aに引き回される配線28dが、電源部支持面24bで露出したネジ26の先端に引っかかることを防止することができる。
FIG. 14 is a perspective sectional view showing a BB ′ section in FIG. 12. As shown in FIGS. 12 and 14, the support member 24 includes a through portion 24 d for passing a wiring 28 d led out from the power supply portion 28. The through portion 24d is provided on the substrate support surface 24a.
Here, as shown in FIG. 7, the support member 24 includes a first substrate fixing portion and a second substrate fixing portion for fixing the substrate group 23 to both ends of the support member 24 in the longitudinal direction. Yes. The first substrate fixing portion and the second substrate fixing portion are, for example, screw holes for attaching screws 26 and the like for fixing the substrate fixing member 25 protruding from the power supply unit support surface 24b at both ends in the longitudinal direction of the support member 24. And so on.
The through portion 24d is preferably provided between the first substrate fixing portion and the second substrate fixing portion. Thereby, it is possible to prevent the wiring 28d routed from the power supply unit support surface 24b to the substrate support surface 24a through the through portion 24d from being caught by the tip of the screw 26 exposed on the power supply unit support surface 24b.

また、図7に示すように、支持部材24は、支持部材24の基板支持面の裏面側(電源部支持面24b)に、発光ユニット20を器具本体10に取り付けるための第1の取付部(第1バネ受部27a)及び第2の取付部(第2バネ受部27b)が設けられている。
貫通部24dは、第1バネ受部27aと第2バネ受部27bとの間に設けられることがより好ましい。これにより、貫通部24dを通して電源部支持面24bから基板支持面24aに引き回される配線28dが、電源部支持面24bで露出したネジ26の先端や、電源部支持面24bに取り付けられた第1バネ受部27a及び第2バネ受部27bに引っかかることを防止することができる。
Further, as shown in FIG. 7, the support member 24 has a first attachment portion (a first attachment portion for attaching the light emitting unit 20 to the instrument main body 10 on the back surface side (power supply portion support surface 24 b) of the substrate support surface of the support member 24.

また、図14に示すように、貫通部24dは、支持部材24の電源部28と対向する位置に設けられることがさらに好ましい。電源部28と対向する位置に貫通部24dを設けることにより、電源部28から導出した配線28dは、支持部材24の電源部支持面24bに露出することなく、貫通部24dを通じて基板支持面24a上の基板群23と接続することができる。このため、配線28dを支持部材24上の広い領域内で引き回す必要がなく、配線28dを短くすることができ、発光ユニット20の組み立て性が向上する。また、配線が28d外部に露出しないため、安全性が向上し、配線の二重被覆が不要となる。   Further, as shown in FIG. 14, the penetrating portion 24 d is more preferably provided at a position facing the power source portion 28 of the support member 24. By providing the through portion 24d at a position facing the power supply portion 28, the wiring 28d led out from the power supply portion 28 is not exposed to the power supply portion support surface 24b of the support member 24, and is exposed on the substrate support surface 24a through the through portion 24d. Can be connected to the substrate group 23. For this reason, it is not necessary to route the wiring 28d in a wide area on the support member 24, the wiring 28d can be shortened, and the assembly of the light emitting unit 20 is improved. Further, since the wiring is not exposed to the outside of the 28d, the safety is improved and the double coating of the wiring becomes unnecessary.

The board fixing member 252 further includes a wiring fixing mechanism 252e that fixes the wirings 23c and 28d connected to the board group 23.
The substrate fixing member 252 is disposed at a position covering the wiring 23c or 28d (see FIG. 12) connected to the light emitting element substrates 231 and 232. In the light emitting unit 20 of the present embodiment, the substrate fixing member 252 is disposed at a joint portion of the light emitting element substrates 231 and 232 in the substrate group 23. The wiring fixing mechanism 252e is formed in a shape that can secure a space through which the wiring 23c or 28d can be led out even when the substrate fixing member 252 is fixed to the support member 24. The wiring 23c or 28d is connected to the light emitting element substrates 231 and 232 through the wiring fixing mechanism 252e. For this reason, by using the substrate fixing member 252, it is possible to prevent the substrate fixing member 25 from pressing the wirings 23c and 28d.

また、基板固定部材252の主部252a、基板押さえ部252b、反射部品保持部252c、及びネジ止め部252dについては、基板固定部材251の主部251a、基板押さえ部251b、反射部品保持部251c及びネジ止め部251dと同様の機能を有する。   The main part 252a, the board pressing part 252b, the reflective component holding part 252c, and the screwing part 252d of the board fixing member 252 are the main part 251a, the board pressing part 251b, the reflective part holding part 251c, and the screw fixing part 252d. It has the same function as the screwing portion 251d.

このような基板固定部材25(基板固定部材251及び252)は、例えば樹脂材料を射出成型することにより形成される。
基板固定部材25は、高反射性材料で形成されることが好ましい。基板固定部材25の一部が基板固定部材25が第1反射部品29a、第2反射部品29b又は第3反射部品29cから露出しても、発光素子21の光を効率よく反射することができるためである。
また、発光素子基板231及び232に接続される配線23c及び28dを覆うように配置される基板固定部材25(図9及び図16に示す基板固定部材25d及び25k)は、透明材料で形成されることが好ましい。基板固定部材25を通して配線23cの配線状態を確認することができるため、基板固定部材25による配線23c及び28dの圧迫をより容易に防止することができる。
Such a substrate fixing member 25 (substrate fixing members 251 and 252) is formed, for example, by injection molding a resin material.
The substrate fixing member 25 is preferably formed of a highly reflective material. Even if a part of the substrate fixing member 25 is exposed from the first reflecting component 29a, the second reflecting component 29b, or the third reflecting component 29c, the light of the light emitting element 21 can be efficiently reflected. It is.
Further, the substrate fixing member 25 (substrate fixing members 25d and 25k shown in FIGS. 9 and 16) disposed so as to cover the wirings 23c and 28d connected to the light emitting element substrates 231 and 232 is formed of a transparent material. It is preferable. Since the wiring state of the wiring 23c can be confirmed through the substrate fixing member 25, it is possible to more easily prevent the wirings 23c and 28d from being pressed by the substrate fixing member 25.

(反射部材)
反射部材29は、発光素子21から照射された光を反射する機能を有する。発光素子21から照射された光は、反射部材29によって予め設定した方向(例えば、床面に向かう方向)へ反射される。反射部材29は、基板群23、支持部材24又は基板固定部材25等の任意の個所で接着剤、ピン、ネジ等によって固定される。
(Reflective member)
The reflection member 29 has a function of reflecting the light emitted from the light emitting element 21. The light emitted from the light emitting element 21 is reflected by the reflecting member 29 in a preset direction (for example, a direction toward the floor surface). The reflection member 29 is fixed by an adhesive, a pin, a screw or the like at an arbitrary position such as the substrate group 23, the support member 24, or the substrate fixing member 25.

図8及び図9に示すように、本実施形態に係る発光ユニット20は、反射部材29として、第1反射部品29aと、第2反射部品29bと、第3反射部品29cとを有している。第1反射部品29aは、発光素子21を露出させかつ基板群23(発光素子基板231及び232で)を被覆している。第2反射部品29bは、第1反射部品29aの幅方向の一端部から、発光素子21からの光の照射方向に向かって傾斜して配置される。第3反射部品29cは、第1反射部品29aの幅方向の他端部から、発光素子21からの光の照射方向に向かって傾斜して配置される。第1反射部品29a、第2反射部品29b及び第3反射部品29cは、互いに異なる部品である。これにより、第1反射部品29a、第2反射部品29b及び第3反射部品29cのそれぞれの取付けが容易になる。   As shown in FIGS. 8 and 9, the light emitting unit 20 according to the present embodiment includes a first reflection component 29 a, a second reflection component 29 b, and a third reflection component 29 c as the reflection member 29. . The first reflective component 29a exposes the light emitting element 21 and covers the substrate group 23 (with the light emitting element substrates 231 and 232). The second reflective component 29b is disposed so as to be inclined from one end portion in the width direction of the first reflective component 29a toward the irradiation direction of the light from the light emitting element 21. The third reflective component 29c is disposed so as to be inclined from the other end portion in the width direction of the first reflective component 29a toward the direction of irradiation of light from the light emitting element 21. The first reflective component 29a, the second reflective component 29b, and the third reflective component 29c are different components. Thereby, each attachment of the 1st reflective component 29a, the 2nd reflective component 29b, and the 3rd reflective component 29c becomes easy.

また、基板群23の発光素子21の実装面側には、図示しない抵抗素子が設けられる場合がある。この場合、第1反射部品29aには、発光素子21を露出させる開口とともに、抵抗素子を露出させる開口が設けられる。
第1反射部品29aに上述した開口を設けることにより、発光素子21から照射された光が第1反射部品29a、第2反射部品29b及び第3反射部品29cの全面で反射され、効率的に照明装置1の発光に利用される。
Further, a resistor element (not shown) may be provided on the mounting surface side of the light emitting element 21 of the substrate group 23. In this case, the first reflecting component 29a is provided with an opening for exposing the light emitting element 21 and an opening for exposing the resistance element.
By providing the above-described opening in the first reflective component 29a, the light emitted from the light emitting element 21 is reflected on the entire surface of the first reflective component 29a, the second reflective component 29b, and the third reflective component 29c, thereby efficiently illuminating. Used for light emission of the device 1.

図19は、第1反射部品29a、第2反射部品29b及び第3反射部品29cを基板固定部材25(25a〜25n)に取り付けた状態を示す斜視図である。図20は、図19に示すC−C’断面を示す断面図である。
図19及び図20に示すように、第2反射部品29bは、第2反射部品29bの幅方向の基板群23に隣接する側の一端が基板群23の幅方向の一端よりも外側に位置するように配置される。また、第3反射部品29cは、第3反射部品29cの幅方向の基板群23に隣接する側の一端が基板群23の幅方向の他端よりも外側に位置するように配置される。すなわち、第2反射部品29b及び第3反射部品29cは、基板群23上に設けられた第1反射部品29a上にかぶらないように配置される。
FIG. 19 is a perspective view showing a state in which the first reflective component 29a, the second reflective component 29b, and the third reflective component 29c are attached to the board fixing member 25 (25a to 25n). 20 is a cross-sectional view showing a CC ′ cross-section shown in FIG.
As shown in FIGS. 19 and 20, the second reflective component 29 b has one end on the side adjacent to the substrate group 23 in the width direction of the second reflective component 29 b positioned outside one end in the width direction of the substrate group 23. Are arranged as follows. The third reflective component 29c is arranged so that one end of the third reflective component 29c adjacent to the substrate group 23 in the width direction is located outside the other end of the substrate group 23 in the width direction. That is, the second reflective component 29 b and the third reflective component 29 c are arranged so as not to fog over the first reflective component 29 a provided on the substrate group 23.

また、第2反射部品29bは、第2反射部品29bの幅方向の基板群23に隣接する側の一端が基板群23の幅方向の一端と隙間なく対向するように配置されることが好ましい。また、第3反射部品29cは、第3反射部品29cの幅方向の基板群23に隣接する側の一端が基板群23の幅方向の他端と隙間なく対向するように配置されることが好ましい。
ここで、本実施形態において「隙間なく対向」とは、第1反射部品29a及び第2反射部品29b、並びに第1反射部品29a及び第3反射部品29cが完全に隙間なく配置される場合に限られない。「隙間なく対向」とは、基板群23(発光素子基板231及び232)の実装面側から見た場合に、第2反射部品29bの幅方向の基板群23に隣接する側の一端の位置と、基板群23の幅方向の一端の位置とが一致することをいう。
The second reflective component 29b is preferably arranged so that one end of the second reflective component 29b adjacent to the substrate group 23 in the width direction faces the one end in the width direction of the substrate group 23 without a gap. The third reflective component 29c is preferably arranged so that one end of the third reflective component 29c adjacent to the substrate group 23 in the width direction faces the other end in the width direction of the substrate group 23 without a gap. .
Here, in this embodiment, “opposing without a gap” is limited to the case where the first reflective component 29a and the second reflective component 29b, and the first reflective component 29a and the third reflective component 29c are completely arranged without a gap. I can't. The term “opposing without a gap” means the position of one end on the side adjacent to the substrate group 23 in the width direction of the second reflective component 29b when viewed from the mounting surface side of the substrate group 23 (light emitting element substrates 231 and 232). This means that the position of one end in the width direction of the substrate group 23 coincides.

第1反射部品29aは、基板固定部材25によって支持部材24の基板支持面24a上で固定される。また、第2反射部品29b及び第3反射部品29cは、支持部材24の凸部24cの頂部と基板固定部材25の一部との間に形成された間隙に嵌め込まれて固定される。具体的には、第2反射部品29b及び第3反射部品29cは、支持部材24の凸部24cの頂部と基板固定部材251の反射部品保持部251cとの間に形成された間隙に嵌め込まれている。これにより、第2反射部品29b及び第3反射部品29cは、支持部材24の凸部24cの頂部の形状に沿って傾斜する。なお、第2反射部品29bと第3反射部品29cは、異なる基板固定部材25で固定されている。   The first reflective component 29 a is fixed on the substrate support surface 24 a of the support member 24 by the substrate fixing member 25. Further, the second reflective component 29 b and the third reflective component 29 c are fitted and fixed in a gap formed between the top of the convex portion 24 c of the support member 24 and a part of the substrate fixing member 25. Specifically, the second reflective component 29b and the third reflective component 29c are fitted into a gap formed between the top of the convex portion 24c of the support member 24 and the reflective component holding portion 251c of the substrate fixing member 251. Yes. Accordingly, the second reflective component 29b and the third reflective component 29c are inclined along the shape of the top of the convex portion 24c of the support member 24. The second reflective component 29b and the third reflective component 29c are fixed by different board fixing members 25.

これにより、組み立て後の発光ユニット20において、第2反射部品29b及び第3反射部品29cが、透光性カバーの内壁面に形成された突出部221c及び221dにそれぞれ向かって傾斜して配置される。すなわち、第2反射部品29bは、第2反射部品29bの幅方向の基板群23に隣接しない側の一端(すなわち、基板群23に隣接する側の一端に対向する他端)が、透光性カバー22の内壁面に形成された突出部221cに向かって傾斜して配置される。また、第3反射部品29cは、第3反射部品29cの幅方向の基板群23に隣接しない側の一端(すなわち、基板群23に隣接する側の一端に対向する他端)が、透光性カバー22の内壁面に形成された突出部221dに向かって傾斜して配置される。これにより、第2反射部品29b又は第3反射部品29cが重量等によって床方向にずれた場合であっても、透光性カバー22の突出部221c又は221dがストッパーとなり、第2反射部品29b又は第3反射部品29cの落下を防止することができる。   Thereby, in the assembled light emitting unit 20, the second reflective component 29b and the third reflective component 29c are arranged to be inclined toward the projecting portions 221c and 221d formed on the inner wall surface of the translucent cover, respectively. . That is, the second reflective component 29b has one end on the side not adjacent to the substrate group 23 in the width direction of the second reflective component 29b (that is, the other end opposite to one end adjacent to the substrate group 23). The cover 22 is disposed to be inclined toward the protrusion 221 c formed on the inner wall surface. In addition, the third reflective component 29c has one end on the side not adjacent to the substrate group 23 in the width direction of the third reflective component 29c (that is, the other end facing the one end adjacent to the substrate group 23). The cover 22 is disposed so as to be inclined toward the protruding portion 221d formed on the inner wall surface. Thus, even when the second reflective component 29b or the third reflective component 29c is displaced in the floor direction due to weight or the like, the protruding portion 221c or 221d of the translucent cover 22 serves as a stopper, and the second reflective component 29b or The third reflective component 29c can be prevented from falling.

また、図21(A)に示すように、基板群23上に配置される第1反射部品29aは、発光素子基板231上に配置される第1反射部品291aと、発光素子基板232上に配置される第1反射部品292aとに分けられる。図21(A)において、第1反射部品291a及び第1反射部品292aを斜線で示す。
このとき、第1反射部品291a及び292aは、電源接続用端子群(コネクタ231a及び232a)と基板接続用端子群(コネクタ231b及び232b)とで囲まれる領域を除いた領域を被複する。すなわち、第1反射部品291aは、基板群23上の、基板群23の一端部からコネクタ231a及び231bの設置位置までを被覆する。また、第1反射部品292aは、基板群23上の、基板群23の他端部からコネクタ232a及び232bの設置位置までを被覆する。なお、図21(A)では、配線23c及び配線28dの図示を省略している。
21A, the first reflective component 29a disposed on the substrate group 23 is disposed on the light-emitting element substrate 232 and the first reflective component 291a disposed on the light-emitting element substrate 231. And the first reflecting component 292a. In FIG. 21A, the first reflective component 291a and the first reflective component 292a are indicated by diagonal lines.
At this time, the first reflective components 291a and 292a overlap areas excluding the area surrounded by the power supply connection terminal group (connectors 231a and 232a) and the board connection terminal group (connectors 231b and 232b). That is, the first reflective component 291a covers the board group 23 from one end of the board group 23 to the installation positions of the connectors 231a and 231b. The first reflective component 292a covers the board group 23 from the other end of the board group 23 to the installation positions of the connectors 232a and 232b. Note that the wiring 23c and the wiring 28d are not illustrated in FIG.

上述した「電源接続用端子群(コネクタ231a及び232a)と基板接続用端子群(コネクタ231a及び232a)とで囲まれる領域」には、発光素子基板231及び232上の対向する短辺側の端部に配置された2個以上の発光素子21が含まれる。図21では、第1反射部品291a及び292aで覆われない領域に、4つの発光素子21が含まれている。   In the “region surrounded by the power supply connection terminal group (connectors 231a and 232a) and the board connection terminal group (connectors 231a and 232a)”, the opposite short-side ends on the light emitting element substrates 231 and 232 are arranged. Two or more light emitting elements 21 arranged in the part are included. In FIG. 21, four light emitting elements 21 are included in a region that is not covered with the first reflective components 291 a and 292 a.

さらに、図21(B)に示すように、発光ユニット20は、2枚の発光素子基板231及び232の短辺を跨いで覆うように配置された基板対向部用反射部品293aを有していてもよい。図21(B)において、第1反射部品291a、第1反射部品292a及び基板対向部用反射部品293aを斜線で示す。
これにより、2枚の発光素子基板231及び232のつなぎ目部分においても発光素子21から照射される光を十分に反射することができるため、基板群23の全面において明るさを均一にすることができる。
Furthermore, as shown in FIG. 21B, the light emitting unit 20 includes a substrate facing portion reflection component 293a disposed so as to cover the short sides of the two light emitting element substrates 231 and 232. Also good. In FIG. 21B, the first reflection component 291a, the first reflection component 292a, and the substrate facing portion reflection component 293a are indicated by hatching.
As a result, the light emitted from the light emitting element 21 can be sufficiently reflected even at the joint portion between the two light emitting element substrates 231 and 232, so that the brightness can be made uniform over the entire surface of the substrate group 23. .

(バネ受部)
図22に示すように、バネ受部27は、器具本体10のバネ部13(図5(B)参照)と係合することにより、発光ユニット20を器具本体10に取り付けた状態を維持することに利用される。具体的には、第1バネ受部27aは器具本体10の第1バネ部13aと係合し、第2バネ受部27bは器具本体10の第2バネ部13bと係合する。すなわち、バネ部13(第1バネ部13a及び第2バネ部13b)とバネ受部27(第1バネ受部27a及び第2バネ受部27b)は、発光ユニット取付凹部111に発光ユニット20を取り付けた状態を維持する取付状態維持部として機能する。なお、取付状態維持部は、発光ユニット20が器具本体10に取り付けた状態が維持されれば、本実施形態で説明するバネ部13及びバネ受部27と異なる形状であってもよい。
(Spring holder)
As shown in FIG. 22, the spring receiving portion 27 maintains the state where the light emitting unit 20 is attached to the instrument main body 10 by engaging with the spring part 13 (see FIG. 5B) of the instrument main body 10. Used for Specifically, the first spring receiving portion 27 a engages with the first spring portion 13 a of the instrument body 10, and the second spring receiving portion 27 b engages with the second spring portion 13 b of the instrument body 10. That is, the spring part 13 (the first spring part 13a and the second spring part 13b) and the spring receiving part 27 (the first spring receiving part 27a and the second spring receiving part 27b) place the light emitting unit 20 in the light emitting unit mounting recess 111. It functions as an attachment state maintaining unit that maintains the attached state. Note that the attachment state maintaining unit may have a shape different from the spring part 13 and the spring receiving part 27 described in the present embodiment as long as the state where the light emitting unit 20 is attached to the instrument body 10 is maintained.

(電源部)
電源部28は、LED等の発光素子21の点灯回路(即ち、電源回路)を内部に収納している。電源部28は、図5で示される器具本体10が取り付けられる天井等の被取付面から発光ユニット取付凹部111内に導出される電力供給ケーブルと接続される。
図22に示すように、電源部28は、電源回路を備える電源基板28aと、絶縁部材28bと、電源基板28a及び絶縁部材28bを内部に収容する電源ボックス28cと、発光素子21に対して電力を供給するための配線28d(配線28dは図22に図示せず)とを有している。
電源部28は、支持部材24に近接して配置される。
(Power supply part)
The power supply unit 28 houses a lighting circuit (that is, a power supply circuit) for the light emitting element 21 such as an LED. The power supply unit 28 is connected to a power supply cable led into the light emitting unit mounting recess 111 from a mounted surface such as a ceiling to which the instrument main body 10 shown in FIG. 5 is mounted.
As shown in FIG. 22, the power supply unit 28 includes a power supply board 28 a including a power supply circuit, an insulating member 28 b, a power supply box 28 c that accommodates the power supply board 28 a and the insulating member 28 b therein, and power for the light emitting element 21. Wiring 28d (wiring 28d is not shown in FIG. 22).
The power supply unit 28 is disposed close to the support member 24.

電源基板28aに備えられた電源回路は、例えば、電力供給ケーブルから供給される交流電力を直流に変換し、その出力(即ち、直流電力)を発光素子21に供給する。電源基板28aは、絶縁部材28bの支持部材24側の面に固定される。
また、図14に示すように、電源基板28aは、電源ボックス28cの内部空間において支持部材24寄りに配置される。
The power supply circuit provided on the power supply board 28 a converts, for example, alternating current power supplied from a power supply cable into direct current, and supplies the output (that is, direct current power) to the light emitting element 21. The power supply substrate 28a is fixed to the surface of the insulating member 28b on the support member 24 side.
Further, as shown in FIG. 14, the power supply board 28a is disposed closer to the support member 24 in the internal space of the power supply box 28c.

絶縁部材28bは、ポリプロピレン、ポリエチレン等の高融点で絶縁性を有する樹脂材料からなる。絶縁部材28bは、支持部材24の電源部支持面24b上に配置される。これにより、電源基板28aは、絶縁部材28b上に配置されて、支持部材24と絶縁される。
なお、絶縁部材28bは、例えばシート状部材を複数回折り曲げた箱型形状であり、電源基板28aの周囲を包んで配置される。
The insulating member 28b is made of a resin material having a high melting point and insulating properties such as polypropylene and polyethylene. The insulating member 28 b is disposed on the power supply unit support surface 24 b of the support member 24. As a result, the power supply substrate 28 a is disposed on the insulating member 28 b and insulated from the support member 24.
The insulating member 28b has, for example, a box shape formed by bending a plurality of sheet-like members, and is disposed so as to surround the power supply substrate 28a.

電源ボックス28cは、プラスチック、アルミニウム又はステンレス等の材料からなる。電源ボックス28cは、電源基板28aを覆う筐体である。
配線28dは、支持部材24の基板支持面24aに設けられた貫通部24dを通って基板群23に接続される。
The power supply box 28c is made of a material such as plastic, aluminum, or stainless steel. The power supply box 28c is a housing that covers the power supply board 28a.
The wiring 28 d is connected to the substrate group 23 through the through portion 24 d provided on the substrate support surface 24 a of the support member 24.

電源部28は、例えば、電源ボックス28cに設けられた図示しない爪部によって支持部材24の電源部支持面24bに固定されている。また、電源部28は、ネジ等の締結部材によって支持部材24の電源部支持面24bに固定されていてもよい。
電源部28は、被取付面の法線方向に見て、図示しない電力供給ケーブルと重なっている。すなわち、電力供給ケーブルは、電源部28の上面と器具本体10との間に確保された電力供給ケーブル収容空間に配線される。このため、電力供給ケーブルによって発光ユニット20の取付けが阻害されることがなくなる。
The power supply unit 28 is fixed to the power supply unit support surface 24b of the support member 24 by, for example, a claw unit (not shown) provided in the power supply box 28c. The power supply unit 28 may be fixed to the power supply unit support surface 24b of the support member 24 by a fastening member such as a screw.
The power supply unit 28 overlaps with a power supply cable (not shown) when viewed in the normal direction of the mounted surface. That is, the power supply cable is wired in a power supply cable housing space secured between the upper surface of the power supply unit 28 and the instrument body 10. For this reason, the attachment of the light emitting unit 20 is not hindered by the power supply cable.

発光ユニット20は、支持部材24の貫通部24dの内側に位置して配線28dを保護する配線保護用絶縁部材を有していてもよい。ここで、貫通部24dの「内側」とは、貫通部24dの中心軸に向かう方向を示す。
発光ユニット20では、支持部材24の貫通部24dを介して電源部28から基板支持面24a側に配線28dが導出される。このとき、配線28dが、支持部材24の貫通部24dの内壁に当たって損傷する可能性がある。例えば、配線28dが被覆材で覆われている場合には、被覆材が剥がれるおそれがある。このため、貫通部24dの内壁と配線28dとが接触しにくくなるような配線保護用絶縁部材を設けることが好ましい。
The light emitting unit 20 may include a wiring protection insulating member that is positioned inside the through portion 24d of the support member 24 and protects the wiring 28d. Here, the “inside” of the penetrating portion 24d indicates a direction toward the central axis of the penetrating portion 24d.
In the light emitting unit 20, the wiring 28 d is led out from the power supply unit 28 to the substrate support surface 24 a side through the through part 24 d of the support member 24. At this time, the wiring 28d may hit and damage the inner wall of the through portion 24d of the support member 24. For example, when the wiring 28d is covered with a covering material, the covering material may be peeled off. For this reason, it is preferable to provide a wiring protection insulating member that makes it difficult for the inner wall of the through portion 24d and the wiring 28d to come into contact with each other.

配線保護用絶縁部材としては、以下のような例が挙げられる。

貫通部24dが支持部材24の電源部28に対向する位置に設けられている場合には、図23(A)に示すように、絶縁部材28bが配線保護用絶縁部材を兼ねることができる。すなわち、電源基板28aと接続された配線28dは、支持部材24の貫通部24dを通って基板支持面24aに設けられた基板群23と接続される。このとき、電源基板28aと支持部材24との間には絶縁部材28bが備えられているため、絶縁部材28bに、貫通部24dよりも小さい貫通部281bを設けて、支持部材24の貫通部24dと絶縁部材28bの貫通部281bとが重なるように絶縁部材28bを配置する。このため、絶縁部材28bによって、支持部材24の貫通部24dと配線28dとを接触しにくくすることができる。
Examples of the wiring protection insulating member include the following.
(1) First Example FIG. 23A is a perspective sectional view showing a BB ′ section of FIG.
When the penetrating portion 24d is provided at a position facing the power supply portion 28 of the support member 24, the insulating member 28b can also serve as an insulating member for wiring protection as shown in FIG. That is, the wiring 28d connected to the power supply substrate 28a is connected to the substrate group 23 provided on the substrate support surface 24a through the through portion 24d of the support member 24. At this time, since the insulating member 28 b is provided between the power supply substrate 28 a and the support member 24, a through portion 281 b smaller than the through portion 24 d is provided in the insulating member 28 b, and the through portion 24 d of the support member 24 is provided. The insulating member 28b is disposed so that the through portion 281b of the insulating member 28b overlaps. For this reason, it is possible to make it difficult for the insulating member 28b to contact the penetrating portion 24d of the support member 24 and the wiring 28d.

(2)第2の例
図23(B)は、電源基板28aと、絶縁部材28bと、支持部材24に設けられた貫通部24dを通じて、基板支持面24a側に導出される配線28dの構成を示す断面図である。
図23(B)に示すように、絶縁部材28bとは異なる部品である配線保護用絶縁部材28eが、支持部材24の基板支持面24a及び電源部支持面24bの少なくとも一方の面(図23(B)では、電源部支持面24b)に密着して設けられていてもよい。配線保護用絶縁部材28eは、例えば、絶縁性を有する樹脂材料で形成される。
図23(B)に示すように、配線保護用絶縁部材28eは、貫通部24dよりも小さい貫通部281eを備えており、支持部材24の貫通部24dと、配線保護用絶縁部材28eの貫通部281eとが重なるように配線保護用絶縁部材28eを配置する。このため、配線保護用絶縁部材28eによって、支持部材24の貫通部24dと配線28dとが接触しにくくなり、配線28dの損傷を抑制することができる。
第2の例の場合、第1の例のように、貫通部24dが支持部材24の電源部28に対向する位置に設けられている必要はない。貫通部24dが支持部材24のどの位置に設けられていても、配線保護用絶縁部材28eが貫通部24dに密着して設けられていればよい。
(2) Second Example FIG. 23B shows the configuration of the wiring 28d led out to the substrate support surface 24a side through the power supply substrate 28a, the insulating member 28b, and the through portion 24d provided in the support member 24. It is sectional drawing shown.
As shown in FIG. 23B, the wiring protection insulating member 28e, which is a component different from the insulating member 28b, is provided on at least one of the substrate support surface 24a and the power supply unit support surface 24b of the support member 24 (FIG. In B), it may be provided in close contact with the power source support surface 24b). The wiring protection insulating member 28e is formed of, for example, an insulating resin material.
As shown in FIG. 23B, the wiring protection insulating member 28e includes a through part 281e smaller than the through part 24d, and the through part 24d of the support member 24 and the through part of the wiring protection insulating member 28e. The wiring protection insulating member 28e is arranged so as to overlap with 281e. For this reason, the wiring protection insulating member 28e makes it difficult for the penetrating portion 24d of the support member 24 and the wiring 28d to come into contact with each other, and damage to the wiring 28d can be suppressed.
In the case of the second example, it is not necessary that the penetrating portion 24d is provided at a position facing the power supply portion 28 of the support member 24 as in the first example. Whatever the position of the penetrating part 24d is provided on the support member 24, the wiring protection insulating member 28e may be provided in close contact with the penetrating part 24d.

(3)第3の例
図23(c)は、電源基板28aと、絶縁部材28bと、支持部材24に設けられた貫通部24dを通じて基板支持面24a側に導出される配線28dとの構成を示す断面図である。
図23(c)に示すように、絶縁部材28bとは異なる部品である配線保護用絶縁部材28eが、少なくとも貫通部24dの内壁を覆って設けられていてもよい。配線保護用絶縁部材28eは、例えば、絶縁性を有する樹脂材料で形成される。
図23(c)に示すように、配線保護用絶縁部材28eは少なくとも貫通部24dの内壁を覆って設けられている。このため、支持部材24の貫通部24dの角部と配線28dとが接触しにくくなり、配線28dの損傷を抑制することができる。
また、配線保護用絶縁部材28eが支持部材24の基板支持面24a及び電源部支持面24bまで覆っていても構わない。この場合、配線保護用絶縁部材28eは、支持部材24の基板支持面24a及び電源部支持面24bと貫通部24dの内壁とで形成される角部を覆っており、より配線28dの損傷を抑制することができる。
第3の例の場合も、貫通部24dが支持部材24の電源部28に対向する位置に設けられている必要はなく、貫通部24dが支持部材24のどの位置に設けられていても、配線保護用絶縁部材28eが貫通部24dの内壁を覆うように設けられていればよい。
(3) Third Example FIG. 23C shows a configuration of the power supply substrate 28a, the insulating member 28b, and the wiring 28d led out to the substrate support surface 24a side through the through portion 24d provided in the support member 24. It is sectional drawing shown.
As shown in FIG. 23C, a wiring protection insulating member 28e, which is a component different from the insulating member 28b, may be provided so as to cover at least the inner wall of the through portion 24d. The wiring protection insulating member 28e is formed of, for example, an insulating resin material.
As shown in FIG. 23C, the wiring protection insulating member 28e is provided so as to cover at least the inner wall of the through portion 24d. For this reason, it becomes difficult for the corner | angular part of the penetration part 24d of the supporting member 24, and the wiring 28d to contact, and damage to the wiring 28d can be suppressed.
Further, the wiring protection insulating member 28e may cover the substrate support surface 24a and the power supply unit support surface 24b of the support member 24. In this case, the insulating member 28e for wiring protection covers the corners formed by the substrate supporting surface 24a and the power source supporting surface 24b of the supporting member 24 and the inner wall of the penetrating portion 24d, thereby further suppressing damage to the wiring 28d. can do.
Also in the case of the third example, it is not necessary that the penetrating part 24d is provided at a position facing the power supply part 28 of the support member 24, and no matter what position of the supporting member 24 the penetrating part 24d is provided, the wiring The protective insulating member 28e may be provided so as to cover the inner wall of the penetrating portion 24d.
