The power supply unit 23 is electrically connected to the light emitting element substrate 22 on which the light emitting element 21 is mounted. The support member 24 supports the power supply unit 23 on the back surface side, and supports the light emitting element substrate 22 and the reflection member 26 on the front surface side. The substrate fixing member 25 fixes the light emitting element substrate 22 to the surface side of the support member 24. The surface side of the support member 24 is entirely covered with a translucent cover 27. The translucent cover 27 is attached to the instrument body 10 together with the support member 24 in a state where the surface side of the support member 24 is covered. Although not shown, a hole is formed between the light emitting element substrate 22 and the substrate fixing member 25 so that the light emitting element 21 is exposed on the light emitting element substrate 22, and the outer dimensions are light emission. A reflector substantially the same as the element substrate 22 is provided. There is almost no gap between the reflector and the substrate fixing member 25.
Here, the light emitting element substrate 22, the support member 24, the reflection member 26, the translucent cover 27, and the reflection plate (not shown) are all in a long shape that is aligned with the instrument body 10 in the longitudinal direction.

(Power supply part)
As shown in FIG. 3, the power supply unit 23 is disposed at the center in the width direction of the lighting device 1 in the internal space of the lighting device 1 (inside the concave portion of the fixture body 10). The power supply unit 23 is fixed to the back surface side of the support member 24 by a fastening member such as a screw.
The power supply unit 23 is electrically connected to the light emitting element substrate 22 via a wiring 23d (see FIG. 12 described later). The wiring 23 d is connected to the light emitting element substrate 22 fixed to the front surface side of the support member 24 from the power supply unit 23 fixed to the back surface side of the support member 24 through the through hole provided in the support member 24. . The power supply unit 23 is connected to, for example, a power supply cable (not shown) led out from the attachment surface of the construction material B to which the instrument body 10 is attached to the internal space of the lighting device 1 and is supplied from the power supply cable. The alternating current power is converted into direct current, and the output (that is, direct current power) is supplied to the light emitting element 21 through the wiring 23d. The power supply cable is wired in a power supply cable housing space secured between the upper surface of the power supply unit 23 and the instrument body 10.

(Support member)
As shown in FIG. 3, the support member 24 supports the light emitting element substrate 22 on which the light emitting element 21 is mounted. The support member 24 also has a function of a heat sink that dissipates heat from the light emitting element 21.
The support member 24 has a long main surface portion 24a, a first side surface portion 24b, a bottom surface portion 24c, and a second side surface portion 24d.

The main surface portion 24a has the light emitting element substrate 22 attached to the front surface side facing downward and the power source portion 23 attached to the back surface side facing upward. The main surface portion 24 a is formed wider than the width of the light emitting element substrate 22.
The first side surface portion 24b is bent from the end portion in the width direction of the main surface portion 24a in the light irradiation direction (that is, the −Z direction in FIG. 3), and extends along the light irradiation direction.

The bottom surface portion 24c extends in the direction intersecting the light irradiation direction from the end portion of the first side surface portion 24b opposite to the end portion in contact with the main surface portion 24a (that is, the Y direction or the -Y direction in FIG. 3). It is bent and extends outward in the width direction of the main surface portion 24a.
The second side surface portion 24d is bent in a direction crossing the bottom surface portion 24c (that is, the Z direction in FIG. 3) from an end portion of the bottom surface portion 24c opposite to the end portion in contact with the first side surface portion 24b. , Stretching to the opposite side of the light irradiation direction. The second side surface portion 24d comes into contact with the inner wall surface in the width direction of the translucent cover 27 described later.

The first side surface portion 24b, the bottom surface portion 24c, and the second side surface portion 24d form convex portions that protrude in the light irradiation direction at both ends of the main surface portion 24a. It is preferable that the top part of the convex part is formed so as to be inclined so as to protrude more outward in the width direction of the support member 24. Moreover, it is preferable that the top part of the convex part has a shape that does not enter the ½ beam angle region of the light emitting element 21. The main surface portion 24a that supports the light emitting element substrate 22 is formed so as to be recessed in the direction of the instrument body 10 (that is, the Z direction in FIG. 3) relative to the convex portion.
The support member 24 fixes the light emitting element substrate 22 by the substrate fixing member 25 mounted on the main surface portion 24a.

(Substrate fixing member)
FIG. 4 is an exploded perspective view for explaining the mounting relationship between the support member 24, the power supply unit 23, and the board fixing member 25.
FIG. 5 is a perspective view for explaining a mounting state of the power supply unit 23 and the board fixing member 25 in the support member 24.
As shown in FIGS. 4 and 5, the power supply unit 23 and seven substrate fixing members 25 (substrate fixing members 251 a to 251 f and a central substrate fixing member 252) are mounted on the support member 24. However, actually, the number of substrate fixing members 25 is not limited to seven. The number of substrate fixing members 25 is arbitrary, and is usually determined according to the design and dimensions of the lighting device 1.

The substrate fixing member 25 (substrate fixing members 251a to 251f, central substrate fixing member 252) is provided on the main surface portion 24a of the support member 24, and fixes the light emitting element substrate 22 to the support member 24.
As shown in FIG. 3, the substrate fixing member 25 has a shape that supports both side portions of the light emitting element substrate 22 in the width direction and protrudes on the light emitting element mounting surface of the light emitting element substrate 22. For this reason, the light emitting element substrate 22 is fixed by the substrate fixing member 25 so as not to float with respect to the support member 24.

  Further, as shown in FIGS. 4 and 5, the power supply unit 23 is attached from above the substrate fixing member 251 c on the back surface side of the main surface portion 24 a of the support member 24. That is, the substrate fixing member 251 c is covered with the power supply unit 23. However, actually, it is not limited to this example.

FIG. 6 is a diagram for explaining the shapes of the substrate fixing members 251a to 251f.
FIG. 7 is a view for explaining the shape of the central substrate fixing member 252.
As shown in FIGS. 6 and 7, the substrate fixing member 25 (substrate fixing members 251a to 251f, central substrate fixing member 252) includes a first claw portion 25a, a second claw portion 25b, and a flat portion 25c. Prepare.

  The first claw portion 25a and the second claw portion 25b are a pair of claw portions formed on the flat surface portion 25c. The first claw portion 25a and the second claw portion 25b are inserted through the insertion holes of the main surface portion 24a of the support member 24 and back surfaces of the main surface portion 24a of the support member 24. Projects from the side to the surface side. The first claw portion 25a and the second claw portion 25b support both side portions of the light emitting element substrate 22 so as to be sandwiched from both sides in the width direction of the light emitting element substrate 22, and on the light emitting element mounting surface of the light emitting element substrate 22. It has a shape protruding. For example, the first claw portion 25a and the second claw portion 25b have a shape in which the tip is bent at a right angle like a heel.

As shown in FIGS. 6 and 7, the front ends of the first claw portion 25 a and the second claw portion 25 b are center portions that are sandwiched between both end portions, with both end portions in the longitudinal direction of the support member 24 being farthest from the flat portion 25 c. Is a shape (for example, arcuate) that is closest to the flat surface portion 25c.
Specifically, the first claw portion 25a and the second claw portion 25b have a length of a portion protruding from the flat surface portion 25c (a portion inserted through the insertion hole of the main surface portion 24a of the support member 24). Both end portions in the longitudinal direction of the first claw portion 25a and the second claw portion 25b are longer than the central portion in the longitudinal direction of the 25a and the second claw portion 25b.
When the light emitting element substrate 22 is mounted, the central portion is in contact with and fixed to the light emitting element substrate 22. The both end portions sandwich the central portion and are further away from the light emitting element substrate 22 than the central portion. The portion protruding from the flat portion 25c approaches the light emitting element substrate 22 as it approaches the central portion from both end portions.

  The flat surface portion 25c is disposed on the back surface side of the main surface portion 24a of the support member 24, and the first claw portion 25a and the second claw portion 25b are provided on the surface facing the back surface side of the main surface portion 24a of the support member 24. . At this time, the first claw portion 25a and the second claw portion 25b pass through the insertion hole of the main surface portion 24a of the support member 24 from the flat surface portion 25c of the substrate fixing member 25 on the back surface side of the main surface portion 24a of the support member 24. Thus, the substrate fixing member 25 is temporarily fixed. In addition, the fixing of the substrate fixing member 25 is completed by attaching the light emitting element substrate 22 between the pair of claws on the surface side of the main surface portion 24 a of the support member 24.

  The flat surface portion 25c may be fixed to the back surface side of the main surface portion 24a of the support member 24 by a fastening member such as a screw. At this time, since the light emitting element substrate 22 is disposed in the region between the first claw portion 25a and the second claw portion 25b on the surface side of the main surface portion 24a of the support member 24, the flat portion 25c is fastened with a screw or the like. The member and its insertion hole are disposed in a portion other than the region between the first claw portion 25a and the second claw portion 25b. For example, a fastening member such as a screw and its insertion hole are provided in the peripheral portion of the flat portion 25c. Accordingly, the substrate fixing member 25 can be fixed with a fastening member such as a screw without affecting the light emitting element substrate 22.

As shown in FIG. 7, the central substrate fixing member 252 further includes a wiring protection part 25d in addition to the first claw part 25a, the second claw part 25b, and the flat part 25c.
The wiring protection part 25d is arranged on the back surface side of the main surface part 24a of the support member 24 in the same manner as the flat surface part 25c, and is connected to the light emitting element substrate 22 from the power supply unit 23 on the back surface side of the main surface part 24a of the support member 24. And covers and protects the through hole. The wiring protection portion 25d has a shape (for example, a semi-cylindrical shape) that can store the wiring 23d disposed on the back surface side of the main surface portion 24a of the support member 24. The wiring protection part 25d may be formed by deforming a part of the plane part 25c.
The wiring 23d led out from the power supply unit 23 is covered with the wiring protection unit 25d, so that it is not exposed on the back surface side of the main surface portion 24a of the support member 24, and the light emitting element substrate 22 on the surface side of the main surface portion 24a through the through hole. Can be connected with. For this reason, it is not necessary to route the wiring 23d in a wide area on the support member 24, the wiring 23d can be shortened, and the assembly of the light emitting unit 20 is improved. Further, since the wiring 23d is not exposed on the back surface side of the main surface portion 24a of the support member 24, safety is improved and double coating of the wiring is not required.

FIG. 9 is a perspective view for explaining a mounting state of the reflection member 26 in the support member 24.
As shown in FIGS. 8 and 9, two reflecting members 26 (a first reflecting member 261 and a second reflecting member 262) are mounted on the support member 24. However, actually, the number of reflection members 26 is not limited to two. For example, one sheet or three or more sheets may be used. That is, the number of the reflection members 26 is arbitrary, and is usually determined according to the design and dimensions of the lighting device 1.

Since the shape is close to the bow (bow shape), the light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) can be easily inserted between the first claw portion 25a and the second claw portion 25b. It has become.

Accordingly, as shown in FIG. 11, both side portions in the width direction of the light emitting element substrate 22 are supported by the first claw portion 25a and the second claw portion 25b.
In FIG. 3, it seems that there is a gap between the light emitting element substrate 22 and the first claw portion 25 a and the second claw portion 25 b of the substrate fixing member 25. In practice, however, a hole is formed between the light emitting element substrate 22 and the substrate fixing member 25 on the light emitting element substrate 22 so that the light emitting element 21 is exposed, and the outer dimensions are the light emitting element substrate. A reflector (not shown) substantially the same as 22 is provided. There is almost no gap between the reflector and the substrate fixing member 25. As a result, the element substrate 22 is fixed to the element substrate mounting portion 24 by the substrate fixing member 25 (the same applies to FIGS. 16, 19, and 22).
Further, as shown in FIG. 3, the central portion in the width direction of the reflecting member 26 (the first reflecting member 261 and the second reflecting member 262) is sandwiched between the light emitting element substrate 22 and the main surface portion 24 a of the support member 24. .

Note that the adjacent light emitting element substrates 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) may not be in contact with each other. Actually, it is only necessary to visually recognize that the adjacent light emitting element substrates 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) are continuous. That is, the adjacent light emitting element substrates 22 (first light emitting element substrate 221, second light emitting element substrate 222) are connected to adjacent light emitting element substrates 22 (first light emitting element substrate 221, second light emitting element substrate 222). 222) means the closest part.
FIG. 13 is an enlarged view for explaining the covering of the wiring at the connecting portion between the adjacent light emitting element substrates 22 (between the first light emitting element substrate 221 and the second light emitting element substrate 222).

  As shown in FIGS. 12 and 13, a power connection terminal to which a wiring 23 d led out from the power supply unit 23 is connected on the light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222).

The power supply connection terminal group and the substrate connection terminal group are respectively arranged in the vicinity of the opposing short sides of the light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222).

  That is, in the vicinity of one short side of the first light emitting element substrate 221, a connector 221a that is a first power connection terminal and a connector 221b that is a first substrate connection terminal are provided. In the vicinity of one short side of the second light emitting element substrate 222, a connector 222a that is a second power connection terminal and a connector 222b that is a second substrate connection terminal are provided. The short side of the first light emitting element substrate 221 on the side where the connector 221a and the connector 221b are provided and the short side of the second light emitting element substrate 222 on the side where the connector 222a and the connector 222b are provided are opposed to each other. . The light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) may have the same configuration.

  As shown in FIGS. 12 and 13, the main surface portion of the support member 24 is provided in the power connection terminal group (connectors 221 a and 222 a) of the light emitting element substrate 22 (first light emitting element substrate 221 and second light emitting element substrate 222). Wirings 23d passing through through holes provided in 24a are respectively connected. Thereby, the electric power supplied from the power supply circuit of the power supply unit 23 is supplied to the light emitting element 21 mounted on the light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) via the wiring 23d. The

  As shown in FIGS. 12 and 13, the substrate connection terminal group (connectors 221 b and 222 b) of the light emitting element substrate 22 (first light emitting element substrate 221 and second light emitting element substrate 222) includes the light emitting element substrate 22 (first light emitting element substrate 22). Wirings 22c for electrically connecting the first light emitting element substrate 221 and the second light emitting element substrate 222) are respectively connected.

  Here, one of the connector 221a and the connector 222a is a plus terminal, and the other is a minus terminal. The electrodes of the connector 221 a and the connector 222 a correspond to the wiring 23 d to be connected and the electrode of the power supply unit 23.

  The connector 221b and the connector 222b are electrically connected by the wiring 22c. Therefore, a plurality of light emitting elements 21 provided on the first light emitting element substrate 221 and a plurality of light emitting elements 21 provided on the second light emitting element substrate 222 are connected in series between the connector 221b and the connector 222b. Connected to.

  With such a configuration, the assembly process of the light emitting element substrate 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) is facilitated. Further, with such a configuration, the wiring 22c for connecting the light emitting element substrates 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) and the wiring 23d from the power supply unit 23 are shortened. can do. For this reason, generation | occurrence | production of noise can be suppressed.

  Further, the power connection terminal group (connectors 221a and 222a) is disposed along one long side of the light emitting element substrate 22 (the light emitting element substrate 22 (the first light emitting element substrate 221, the second light emitting element substrate 222)). The board connecting terminal group (connectors 221b and 222b) is disposed along the other long side of the light emitting element substrate 22 (light emitting element substrate 22 (first light emitting element substrate 221, second light emitting element substrate 222)). .

  At this time, it is preferable that the connectors 221 a and 222 a are arranged on the light emitting element substrate 22 via at least one light emitting element 21. The connectors 221b and 222b are preferably arranged via at least one light emitting element 21. This is to ensure the creepage distance between the connectors 221a and 222a and the connectors 221b and 222b.

  12 and 13, the connectors 221a and 221b are provided at the light emitting element 21 provided at the position closest to the short side of the first light emitting element substrate 221, and at the position closest to the short side. It is preferable to be provided in a region between the light emitting elements 21 formed. Further, the connectors 221a and 221b are provided in a position closer to the light emitting element 21 provided in the position closest to the short side than the light emitting element 21 provided in the position closest to the short side in the above-described region. It is preferred that

  Similarly, the connectors 222a and 222b are regions between the light emitting element 21 provided at the position closest to the short side of the second light emitting element substrate 222 and the light emitting element 21 provided at the position closest to the short side. It is preferable to be provided. Further, the connectors 222a and 222b are provided in a position closer to the light emitting element 21 provided in the position closest to the short side than the light emitting element 21 provided in the position closest to the short side in the above-described region. It is preferred that

  Accordingly, the light emitting element substrate 22 (first light emitting element) is secured while ensuring the creepage distance between the connectors 221a and 222a arranged along the same long side of the light emitting element substrate 22 and between the connectors 221b and 222b. Since the continuity of the arrangement of the light emitting elements 21 can be ensured also in the connecting portion of the substrate 221 and the second light emitting element substrate 222), the light emitting element substrate 22 (first light emitting element substrate 221, second light emitting element) of the light emitting unit 20 is secured. The brightness can be made uniform over the entire surface of the element substrate 222).

As shown in FIG. 13, the wiring 22c and the wiring 23d are disposed outside the connecting portion between the adjacent light emitting element substrates 22 (the first light emitting element substrate 221 and the second light emitting element substrate 222) in the width direction. Covered and protected by the part 28 (power connection wiring restraint part 28a, board connection wiring restraint part 28b).
Thereby, the wiring suppression unit 28 (the power supply connection wiring suppression unit 28a and the substrate connection wiring suppression unit 28b) allows the light emitting element substrates 22 adjacent to each other with the wiring 22c and the wiring 23d (the first light emitting element substrate 221 and the second light emitting element). It is possible to prevent the element substrate 222) from floating on the connecting portion. Therefore, it is possible to prevent the wiring from floating on the connecting portion and the optical characteristics of the connecting portion from being different from those of other portions.

The power connection wiring restraint portion 28a is positioned so as to cover the wiring 23d connected to the power connection terminal group (connectors 221a and 222a) of the light emitting element substrate 22 (first light emitting element substrate 221 and second light emitting element substrate 222). Be placed.
Similarly, the board connection wiring restraint portion 28b connects the wiring 22c connected to the board connection terminal group (connectors 221b and 222b) of the light emitting element substrate 22 (first light emitting element substrate 221 and second light emitting element substrate 222). It is arranged at the position to cover.

Such a wiring restraint part 28 (power connection wiring restraint part 28a, board connection wiring restraint part 28b) is formed, for example, by injection molding a resin material.
Note that the wiring suppression unit 28 (power connection wiring suppression unit 28a, board connection wiring suppression unit 28b) may be formed of, for example, a highly reflective material. By forming it with a highly reflective material, the wiring restraint portion 28 (the power supply wiring restraint portion 28a, the board connection wiring restraint portion 28b) is connected to the reflecting member 26 (the first reflecting member 261 and the second reflecting member 262). Similarly, the light of the light emitting element 21 can be reflected efficiently.
Alternatively, the wiring suppression unit 28 (power supply connection wiring suppression unit 28a, substrate connection wiring suppression unit 28b) may be formed of, for example, a transparent material. By forming the transparent material, it is possible to check the wiring states of the wiring 22c and the wiring 23d through the wiring suppression unit 28 (power supply connection wiring suppression unit 28a, substrate connection wiring suppression unit 28b).

(Translucent cover)
The translucent cover 27 covers the surface side of the main surface portion 24a of the support member 24 (the surface side on which the light emitting element substrate 22 and the reflecting member 26 are mounted), and when the light emitting unit 20 is attached to the instrument body 10, The main body 10 has a shape that partly enters the inside of the recess. At this time, at least a part of the outer wall surfaces at both ends in the width direction of the translucent cover 27 abuts at least a part of the inner wall surfaces of the first side edge 111b and the second side edge 111c of the instrument body 10. The translucent cover 27 is, for example, white, and has a function of diffusing light emitted from the light emitting element 21 (light diffusibility).

  As shown in FIG. 2, the translucent cover 27 includes a main cover 271 and a first end cover 272a and a second end cover 272b. The main cover 271 covers the light emitting element substrate 22 on which the light emitting element 21 is mounted. The first end cover 272a is attached so as to cover one end of the main cover 271. Similarly, the second end cover 272b is attached so as to cover the other end of the main cover 271.

Moreover, as shown in FIG. 3, the 1st protrusion part 271a and the 2nd protrusion part 271b are formed in each inner wall surface of the both sides of the width direction of the main cover 271. As shown in FIG. The first projecting portion 271a and the second projecting portion 271b are separated in the vertical direction (that is, the ± Z direction in FIG. 3) and extend in the longitudinal direction of the main cover 271 in parallel with each other. In addition, the shape of the 1st protrusion part 271a and the 2nd protrusion part 271b does not need to be the same.

  The first protrusion 271a and the second protrusion 271b fix the second side face 24d of the support member 24. At this time, the first projecting portion 271a and the second projecting portion 271b are in contact with the second side surface portion 24d of the support member 24 on both sides of the main cover 271 in the width direction. For example, the second side surface portion 24d of the support member 24 is fitted between the first protrusion portion 271a and the second protrusion portion 271b. Alternatively, the first projecting portion 271a and the second projecting portion 271b may sandwich the second side surface portion 24d of the support member 24. With this configuration, the support member 24 can be fixed to the translucent cover 27 by the first projecting portion 271a and the second projecting portion 271b, and the support member 24 falls off the translucent cover 27. Can be more reliably prevented.

  Further, the second protruding portion 271b and the bottom surface portion 24c of the support member 24 may sandwich the peripheral edge portion of the reflecting member 26 in the width direction. With this configuration, the peripheral edge portion of the reflecting member 26 in the width direction can be fixed to the bottom surface portion 24 c of the support member 24 by the second projecting portion 271 b and the bottom surface portion 24 c of the support member 24. It is possible to prevent the reflecting member 26 from falling off from the bottom surface portion 24c. In addition, when the peripheral part of the width direction of the reflection member 26 is separately fixed to the bottom face part 24c of the support member 24 by adhesive etc. (for example, double-sided tape), the 2nd protrusion part 271b and the bottom face of the support member 24 are provided. The part 24c may not sandwich the peripheral part of the reflecting member 26 in the width direction.

The light emitting unit 20 is attached such that part of both side surfaces of the translucent cover 27 enters the opening of the instrument body 10. At this time, the light emitting unit 20 is configured so that a part of both side surfaces of the translucent cover 27 is in contact with the inner wall surfaces (the first side edge portion 111b and the second side edge portion 111c) of the recess of the device body 10. It is attached to the main 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 a part of the translucent cover 27 that has entered the recess is exposed, and no gap is generated between the instrument body 10 and the light emitting unit 20.

(Effect of 1st Embodiment)
According to the illuminating device which concerns on 1st Embodiment demonstrated above, the following effects can be acquired.
(1) In the lighting device according to the first embodiment of the present invention, the light emitting element is mounted on the light emitting element substrate, the light emitting element substrate is attached to the surface side of the support member, and the substrate fixing member attaches the light emitting element substrate to the support member. A translucent cover is attached so as to be fixed to the front surface side and cover the front surface side of the support member, and the translucent cover in a state of covering the front surface side of the support member is attached to the instrument body. The light emitting substrate, the support member, the translucent cover, and the instrument main body are all in a long shape with the same longitudinal direction. A plurality of light emitting element substrates are connected in the longitudinal direction. The pair of claw portions of the substrate fixing member is hooked from the outer side in the short direction of the light emitting element substrate to the end portion in the longitudinal direction at the connecting portion where the light emitting element substrates are connected to each other.
As a result, the adjacent light emitting element substrates can be fixed by the pair of claws, and the influence on the light distribution characteristics and visibility can be minimized. Further, the light emitting element substrate is adjacent to the connecting portion while preventing the light emitting element substrate from floating from the support member and preventing one of the adjacent light emitting element substrates from riding on the other light emitting element substrate. It becomes possible to make it difficult to visually recognize the joint of the connection portion between the light emitting element substrates.
(2) The substrate fixing member is disposed across both the adjacent light emitting element substrates. Each of the pair of claws is caught by both adjacent light emitting element substrates.
As a result, since one nail portion simultaneously suppresses both adjacent light emitting element substrates, the light emitting element substrate floats from the support member near the connecting portion, or one of the adjacent light emitting element substrates is the other light emitting element substrate. It is possible to prevent the light emitting element substrate from getting on.

(3) The pair of claw portions are disposed on both sides of the light emitting element substrate in the short direction at the connection portion, face each other, protrude along the main emission direction of light emitted from the light emitting element, and the protruding portion emits light The element substrate is bent toward the inner side in the short direction.
As a result, the pair of claw portions can be optimally arranged at the connecting portion between the adjacent light emitting element substrates, and both light emitting element substrates can be appropriately suppressed.

(4) The flat surface portion of the substrate fixing member is disposed on the surface of the support member opposite to the surface on which the light emitting element substrate is attached, and a pair of claw portions is provided. The support member and the reflection member each have an insertion hole through which the pair of claw portions are inserted. The pair of claw portions are inserted through the insertion holes of the support member and the reflection member from the flat portion, projecting to the surface to which the light emitting element substrate of the support member is attached, and fix the light emitting element substrate.
As a result, the shape of the substrate fixing member having the pair of claw portions can be made an optimum shape. Further, the substrate fixing member can be fixed to the support member without using a fastening member such as a screw.

(5) The connector disposed between the adjacent light emitting elements on the light emitting element substrate and the connector of the adjacent light emitting element substrate passing through the outer side in the short direction of the light emitting element substrate at the connecting portion are electrically connected. It further has a wiring and a wiring restraining part that holds the wiring.
As a result, it is possible to prevent the wiring that electrically connects the light emitting element substrates from being lifted on the light emitting element substrate at the connection part between the adjacent light emitting element substrates and affecting the light distribution characteristics of the connection part. Is possible.

(6) The translucent cover is white and has light diffusibility.
As a result, it is possible to suppress the attenuation of the illuminance and luminance of the light emitted from the light emitting element, incident on the translucent cover and transmitted into the living room, and efficiently diffuse it into the living room.

(7) The light emitting element is an LED chip.
As a result, it is possible to provide a lighting device that is excellent in durability and economy.
