The instrument body 12 supports a long light source module 14 that is an attachment target. In this example, the light source 26 is provided in the light source module 14. FIG. 1B shows a state where the light source module 14 is removed.

  The light source module 14 irradiates light emitted from the light source 26. For example, the luminaire 10 is attached to the ceiling of the room with the light source module 14 facing downward. The lighting fixture 10 illuminates the room with light emitted from the light source module 14. In addition, you may attach the lighting fixture 10 to a wall surface etc., for example, without restricting to a ceiling. The luminaire 10 may be used for outdoor lighting, for example. The instrument body 12 is attached to the ceiling with screws or the like, for example. Thus, the fixture body 12 is used for supporting the light source module 14 and for attaching the lighting fixture 10 to a ceiling or the like.

  The instrument body 12 is provided with, for example, a power supply device 15 and a terminal block 16. The power supply device 15 and the terminal block 16 are attached to the instrument body 12 by, for example, screwing.

  For example, the power supply device 15 converts electric power supplied from the outside into a voltage or current corresponding to the light source module 14 and supplies the converted voltage or current to the light source module 14. The light source module 14 turns on the light source 26 according to the power supply from the power supply device 15 and emits light.

As illustrated in FIGS. 2 to 5, the light source module 14 includes a support body 21, a cover 22, and a holding member 23.

  The support 21 supports the substrate 25. The substrate 25 has a first surface 25a and a second surface 25b. The second surface 25b is a surface opposite to the first surface 25a. The support 21 supports the substrate 25 from the second surface 25b side. The board | substrate 25 may be fixed to the support body 21 by adhesion | attachment etc., and may be attached to the support body 21 so that attachment or detachment is possible by screwing. The support 21 may support the substrate 25 in a detachable manner.

  A light source 26 is provided on the substrate 25. The substrate 25 is provided with a plurality of light sources 26, for example. Each light source 26 is arranged side by side on the first surface 25 a of the substrate 25. For example, a wiring layer (not shown) is provided on the substrate 25, and the light sources 26 are electrically connected to each other through the wiring layer. The number of the light sources 26 may be arbitrary. For example, the number of the light sources 26 may be one.

  For example, a light emitting diode (LED) is used as the light source 26. The light source 26 may be, for example, an organic light emitting diode (OLED), an inorganic electroluminescent light emitting element, an organic electroluminescent light emitting element, or another electroluminescent light emitting element. Good. The light source 26 may be a light bulb, for example.

  The cover 22 is attached to the support body 21 and covers the substrate 25 supported by the support body 21. The cover 22 protects the substrate 25 and each light source 26 from, for example, external force or dust. The cover 22 is light transmissive. The cover 22 is light transmissive with respect to the light emitted from each light source 26. The cover 22 is transparent, for example. The cover 22 may have, for example, light diffusibility. For the cover 22, for example, a light transmissive resin material is used.

  The holding member 23 holds the cover 22 on the support body 21. That is, the holding member 23 prevents the cover 22 from being detached from the support body 21. For example, the light source module 14 is provided with a plurality of holding members 23. In this example, three holding members 23 are provided. The number of holding members 23 may be arbitrary. The number of holding members 23 may be one or two, for example, and may be four or more.

  The support 21 has a first portion 31, a second portion 32, and a third portion 33. The first portion 31 has a front surface 31a extending in the first direction and a back surface 31b opposite to the front surface 31a. The first portion 31 has a plate shape. The first portion 31 is, for example, a long plate that is long in the first direction. In this example, the front surface 31a and the back surface 31b are substantially rectangular. The shape of the front surface 31a and the shape of the back surface 31b are not limited to a rectangular shape, and may be any shape extending in the first direction. In this example, the back surface 31b is substantially parallel to the front surface 31a.

  Hereinafter, a direction (X-axis direction) parallel to the first direction represented by an arrow X in the figure is referred to as a “longitudinal direction”. A direction (Y-axis direction) that is parallel to the surface 31a and perpendicular to the longitudinal direction (Y-axis direction) represented by an arrow Y in the figure is referred to as a “width direction”. A direction (Z-axis direction) perpendicular to the longitudinal direction and the width direction, indicated by an arrow Z in the figure, is referred to as a “height direction”. The height direction is a direction perpendicular to the surface 31a.

  The second portion 32 is provided on one side end 31p extending in the longitudinal direction of the back surface 31b. The second portion 32 extends in the direction facing the back surface 31b. In other words, the second portion 32 extends in a direction from the front surface 31a toward the back surface 31b.

  The third portion 33 is provided at the other side end 31q extending in the longitudinal direction of the back surface 31b. The third portion 33 extends in the direction facing the back surface 31b.

  In this example, the shape of the support 21 viewed in the longitudinal direction is substantially U-shaped. The second portion 32 and the third portion 33 are so-called ribs. The shape of the support 21 viewed in the longitudinal direction may be, for example, an H shape. That is, the second portion 32 and the third portion 33 only need to extend at least in the direction toward the back surface 31b, and may further extend in the direction toward the front surface 31a. In this example, the second portion 32 and the third portion 33 extend in a direction substantially perpendicular to the back surface 31b. The second portion 32 and the third portion 33 may be inclined with respect to the back surface 31b. For the support 21, for example, a metal material such as iron, aluminum, or stainless steel is used. The support 21 is formed, for example, by bending a metal plate.

  In this example, the support body 21 is provided with one second portion 32 extending in the longitudinal direction along one side end 31p of the back surface 31b. One third portion 33 extending in the longitudinal direction is provided along the other side end 31q of the back surface 31b. For example, a plurality of second portions 32 arranged in the longitudinal direction may be provided, or a plurality of third portions 33 arranged in the longitudinal direction may be provided.

  The support 21 supports the substrate 25 with the surface 31a. The substrate 25 is provided on the surface 31a. The support 21 supports the substrate 25 with the first surface 25a of the substrate 25 facing the surface 31a. Thereby, light is irradiated in the direction which the surface 31a faces.

  In addition, the width (length in the width direction) of the surface 31 a is longer than the width of the substrate 25. For this reason, one end 31m extending in the longitudinal direction of the surface 31a and the other end 31n extending in the longitudinal direction of the surface 31a are not covered by the substrate 25 even when the substrate 25 is supported.

  The cover 22 includes a main body portion 40, a first contact portion 41, a second contact portion 42, a first engagement portion 43, and a second engagement portion 44.

  The main body 40 faces the first surface 25a of the substrate 25 supported by the surface 31a and covers the substrate 25. The main body portion 40 includes, for example, a first plate portion 40a facing the first surface 25a, a second plate portion 40b extending from one end in the width direction of the first plate portion 40a toward the first surface 25a side, and a first plate portion 40a. And a third plate portion 40c extending from the other end in the width direction of the plate portion 40a toward the first surface 25a.

  In this example, the second plate portion 40b and the third plate portion 40c are inclined with respect to the first surface 25a. The second plate portion 40 b and the third plate portion 40 c are inclined portions that are inclined so as to expand from the substrate 25 side toward the light emission direction of the light source 26 in the width direction of the light source module 14. The distance D1 in the width direction between the second plate portion 40b and the third plate portion 40c becomes longer in the direction from the first surface 25a toward the first plate portion 40a (light emission direction). For example, the distance D1 in the width direction between the second plate portion 40b and the third plate portion 40c continuously increases in the direction from the first surface 25a toward the first plate portion 40a. That is, the second plate portion 40b and the third plate portion 40c are tapered. The shape of the main body 40 viewed in the longitudinal direction is, for example, a fan shape. Thereby, for example, when the light source module 14 is installed on the ceiling, part of the light emitted from the light source module 14 is directed toward the ceiling from the second plate portion 40b and the third plate portion 40c.

  The first contact portion 41 is provided at one end of the main body portion 40 in the width direction. The first contact portion 41 is provided, for example, at the end of the second plate portion 40b opposite to the first plate portion 40a. The first contact portion 41 contacts one side end 31m of the surface 31a.

  The second contact portion 42 is provided at the other end of the main body portion 40 in the width direction. The second contact portion 42 is provided, for example, at the end of the third plate portion 40c opposite to the first plate portion 40a. The second contact portion 42 contacts the other side end 31n of the surface 31a.

  In this example, the first contact portion 41 and the second contact portion 42 are in direct contact with the surface 31a. The 1st contact part 41 and the 2nd contact part 42 do not necessarily need to contact the surface 31a directly. The first contact part 41 and the second contact part 42 may contact the surface 31a with another member interposed therebetween.

  The first engaging portion 43 is provided at one end of the main body portion 40 in the width direction. The first engaging portion 43 engages with the end portion 32 a in the height direction of the second portion 32, and sandwiches the second portion 32 together with the first contact portion 41. The first engaging portion 43 covers the second portion 32 from the outside, for example.

  The second engaging portion 44 is provided at the other end of the main body portion 40 in the width direction. The second engaging portion 44 engages with the end portion 33 a in the height direction of the third portion 33, and sandwiches the third portion 33 together with the second contact portion 42. For example, the second engaging portion 44 covers the third portion 33 from the outside.

  Thus, the cover 22 covers the support 21 from the surface 31 a side, and engages the engaging portions 43 and 44 with the second portion 32 and the third portion 33. As a result, the cover 22 is attached to the support 21.

  The light source module 14 further includes a pair of side plates 27 and 28. The side plate 27 is attached to one end in the longitudinal direction of the support 21 and the cover 22. The side plate 28 is attached to the other end in the longitudinal direction of the support 21 and the cover 22. The side plate 27 closes one end of the cover 22 in the longitudinal direction. The side plate 28 closes the other end of the cover 22 in the longitudinal direction.

  The holding member 23 includes a facing portion 50, a first grip portion 51, and a second grip portion 52. The facing part 50 faces the back surface 31b. The facing portion 50 is in contact with the back surface 31b, for example. The length in the width direction of the facing portion 50 is substantially the same as or slightly shorter than the length in the width direction of the back surface 31b.

  The first grip 51 is provided at one end of the facing portion 50 in the width direction. The first holding part 51 holds the second part 32 and the first engaging part 43 in between. The 1st holding part 51 is leaf spring shape, for example, and suppresses that engagement of the 1st engaging part 43 is canceled by pinching the 2nd portion 32 and the 1st engaging part 43. .

  The second grip portion 52 is provided at the other end in the width direction of the facing portion 50. The second grip portion 52 grips the third portion 33 and the second engagement portion 44 in between. The second grip 52 is, for example, a leaf spring, and suppresses the engagement of the second engagement portion 44 from being released by sandwiching the third portion 33 and the second engagement portion 44. . In other words, the holding member 23 suppresses the opening of the cover 22 by being sandwiched between the grip portions 51 and 52.

  As described above, the holding member 23 is attached to the support 21 from the back surface 31b side, sandwiches the second portion 32 and the first engagement portion 43 with the first grip portion 51, and engages with the third portion 33 and the second engagement. The cover 22 is held on the support 21 by sandwiching the portion 44 with the second grip portion 52.

  The first grip 51 is provided with a first stopper 53. The first stopper portion 53 engages with the first engaged portion 32b provided in the second portion 32, and moves in the direction toward the back surface 31b of the first grip portion 51 (the direction away from the back surface 31b). To regulate.

  The second grip portion 52 is provided with a second stopper portion 54. The second stopper portion 54 engages with the second engaged portion 33 b provided in the third portion 33 and restricts the movement of the second grip portion 52 in the direction in which the back surface 31 b faces.

  Each stopper part 53 and 54 is engaged in the state which made the opposing part 50 contact the back surface 31b. As a result, the holding member 23 is held on the support 21. The holding member 23 is prevented from being detached from the support body 21. Therefore, the cover 22 is appropriately held by the support 21.

  In this example, three holding members 23 are attached to the support 21. Accordingly, the first portion to be engaged 32b is provided in the second portion 32 side by side in the longitudinal direction. The third portion 33 is provided with three second engaged portions 33b arranged in the longitudinal direction. For example, the position where the first engaged portion 32 b and the second engaged portion 33 b are provided is the attachment position of the holding member 23.

  In this example, the first stopper portion 53 and the second stopper portion 54 are substantially hemispherical protrusions protruding outward, and the first engaged portion 32b and the second engaged portion 33b are substantially rectangular. It is a through-hole of shape. On the contrary, the first stopper portion 53 and the second stopper portion 54 may be through holes, and the first engaged portion 32b and the second engaged portion 33b may be protrusions. Each shape of the 1st stopper part 53, the 2nd stopper part 54, the 1st to-be-engaged part 32b, and the 2nd to-be-engaged part 33b may be arbitrary shapes which can suppress the detachment | leave of the holding member 23. FIG.

  In this example, two first stopper portions 53 and two second stopper portions 54 are provided side by side in the longitudinal direction. The number of each of the first stopper portion 53 and the second stopper portion 54 is arbitrary. Each of the 1st stopper part 53 and the 2nd stopper part 54 may be one, and may be three or more.

  The first holding part 51 is provided with a pair of holding parts 51a and a first claw part 51b. Each holding part 51a is provided side by side in the longitudinal direction. Each holding portion 51 a is a portion that is bent into a substantially U shape and sandwiches the second portion 32 and the first engaging portion 43. The 1st nail | claw part 51b is provided between each holding | suppressing part 51a. The first claw portion 51b protrudes in the opposite direction to the facing portion 50 in a direction substantially parallel to the back surface 31b. For example, the first claw portion 51b protrudes outward in the width direction.

  The second grip portion 52 is provided with a pair of holding portions 52a and a second claw portion 52b. Each holding part 52a is provided side by side in the longitudinal direction. Each holding portion 52 a is a portion that is bent into a substantially U shape and sandwiches the third portion 33 and the second engaging portion 44. The 2nd nail | claw part 52b is provided between each holding | suppressing part 52a. The 2nd nail | claw part 52b protrudes toward the direction opposite to the opposing part 50 in the direction substantially parallel to the back surface 31b. For example, the second claw portion 52b protrudes outward in the width direction.

  Each claw part 51b, 52b is used for attachment of the light source module 14 to the instrument body 12. As described above, the holding member 23 is used to hold the cover 22 and is also used to attach the light source module 14 to the instrument body 12.

  For the holding member 23, for example, a metal material such as iron, aluminum, or stainless steel is used. For the holding member 23, for example, a resin material or the like may be used. However, the holding member 23 is preferably made of the metal material as described above. Thereby, for example, the durability of the holding member 23 can be improved. Further, the holding member 23 is made of, for example, a single plate material. Thereby, for example, the number of parts can be reduced. For example, the cost of the light source module 14 can be reduced. For example, when a resin material is used for the holding member 23, the holding member 23 is preferably a single part formed by injection molding or the like.

  In the light source module 14, after the substrate 25 is supported by the support 21, the engagement portions 43 and 44 are engaged, the cover 22 is attached to the support 21, and the cover 22 is held on the support 21 by the holding member 23. To do. The side plate 27 closes one end of the cover 22 in the longitudinal direction, and the side plate 28 closes the other end of the cover 22 in the longitudinal direction. Thereby, the light source module 14 is assembled.

  The cover 22 is not limited to the holding member 23 and may be held on the support 21 by, for example, screwing. However, when the cover 22 is held by the holding member 23, the light source module 14 can be assembled without using a tool or the like. For example, the assemblability of the light source module 14 can be improved as compared with the case where screws are used. In addition, the number of parts can be reduced as compared with the case of using screws. For example, the cost of the light source module 14 can be reduced.

FIG. 6 is a cross-sectional view schematically illustrating the lighting fixture according to the first embodiment.
As shown in FIGS. 1 and 6, the instrument body 12 includes a housing 60, an attachment member 61, and a regulating member 62.
The housing 60 includes a long bottom plate portion 70 and a pair of side plate portions 71 and 72 extending from both ends in the width direction of the bottom plate portion 70. The housing 60 accommodates at least a part of the light source module 14 in a region 60 a surrounded by the bottom plate portion 70 and the pair of side plate portions 71 and 72. In this example, the region 60 a accommodates a part of the light source module 14. The region 60a may accommodate the entire light source module 14.

  The bottom plate part 70 has an inner surface 70a facing the region 60a side and an outer surface 70b facing the region 60a. The inner surface 70 a faces the back surface 31 b of the support 21. More specifically, the inner surface 70a faces the entire back surface 31b. The bottom plate portion 70 is also a long plate extending in the X-axis direction. In this example, the outer surface 70b is substantially parallel to the inner surface 70a. The outer surface 70b may be non-parallel to the inner surface 70a. In this example, the inner surface 70a is substantially parallel to the rear surface 31b. The inner surface 70a may be non-parallel to the rear surface 31b. The power supply device 15 and the terminal block 16 are accommodated in the area 60a, for example. The power supply device 15 and the terminal block 16 are attached to the inner surface 70a, for example.

  The bottom plate portion 70 is provided with openings 70c and 70d. The opening 70c is disposed at a position facing the first grip 51 in the height direction. The opening 70d is disposed at a position facing the second grip 52 in the height direction. In this example, three openings 70c and three openings 70d are provided for each of the three holding members 23 of the light source module 14.

  The side plate portion 71 extends from one end in the width direction of the inner surface 70a in the direction toward the inner surface 70a. The side plate portion 72 extends in the direction from the other end in the width direction of the inner surface 70a toward the inner surface 70a. In this example, the side plate portions 71 and 72 extend in a direction substantially perpendicular to the inner surface 70a. That is, in this example, the side plate portions 71 and 72 extend in the height direction. Each of the side plate portions 71 and 72 may be inclined with respect to the inner surface 70a. For example, the side plate portion 71 faces the first grip portion 51 in the width direction. For example, the side plate portion 72 faces the second grip portion 52 in the width direction.

  The attachment member 61 has a pair of engaging portions 61a and 61b that face each other in the width direction. The attachment member 61 engages the pair of engaging portions 61a and 61b with the light source module 14 accommodated in the region 60a. For example, the attachment member 61 engages the engaging portions 61 a and 61 b with the claw portions 51 b and 52 b of the light source module 14. Thereby, the attachment member 61 attaches the light source module 14 to the housing 60. In other words, the attachment member 61 restricts the movement of the light source module 14 in the direction away from the region 60a.

  Thus, the instrument main body 12 supports the light source module 14 by engaging the engaging portions 61a and 61b of the mounting member 61 with the claw portions 51b and 52b. In this example, the light source module 14 is provided with three holding members 23. For this reason, in this example, the three attachment members 61 are provided in the instrument main body 12. Each attachment member 61 is attached to the housing 60 at a position corresponding to each holding member 23 of the light source module 14. The instrument main body 12 supports the light source module 14 by engaging the mounting members 61 with the respective claw portions 51 b and 52 b of the holding members 23.

  The attachment member 61 is attached to the bottom plate part 70. In this example, the attachment member 61 is attached to the outer surface 70b. The attachment member 61 has a first extending portion 61 c along the bottom plate portion 70, a second extending portion 61 d along the side plate portion 71, and a third extending portion 61 e along the side plate portion 72. The attachment member 61 is, for example, a plate-like member that is bent into a substantially U shape. In this example, the second extending portion 61d enters the region 60a through the opening 70c. The third extending portion 61e enters the region 60a through the opening 70d.

  In addition, the 2nd extension part 61d should just have the component extended in a height direction at least. That is, the second extending portion 61 d may be non-parallel to the side plate portion 71. Similarly, the 3rd extension part 61e should just have at least the component extended in a height direction. The third extending portion 61e may be non-parallel to the side plate portion 72.

  The one engaging portion 61a is formed, for example, by bending the end portion of the second extending portion 61d toward the inside (the first extending portion 61c side). The other engaging portion 61b is formed by, for example, bending the end portion of the third extending portion 61e toward the inside (the first extending portion 61c side). The attachment member 61 sandwiches the light source module 14 between the engaging portions 61 a and 61 b and engages the engaging portions 61 a and 61 b with the light source module 14.

  Moreover, the 1st nail | claw part 51b inclines in the direction which the surface 31a faces with respect to the plane parallel to the surface 31a. Similarly, the 2nd nail | claw part 52b inclines in the direction which the surface 31a faces with respect to the plane parallel to the surface 31a. That is, each claw part 51b, 52b is inclined toward the light irradiation direction side. Thereby, for example, the degree of engagement between the engaging portion 61a and the first claw portion 51b can be increased. For example, the degree of engagement between the engaging portion 61b and the second claw portion 52b can be increased.

  In addition, the shape of the to-be-engaged part engaged with each engaging part 61a, 61b by the side of the light source module 14 is not limited to nail | claw shape. The shape of the engaged portion on the light source module 14 side may be, for example, a groove shape. The shapes of the engaging portions 61a and 61b and the shape of the engaged portion on the light source module 14 side may be any shapes that engage with each other.

  In this example, the first extending portion 61c is attached to the outer surface 70b, and the engaging portions 61a and 61b are caused to enter the region 60a from the openings 70c and 70d provided in the bottom plate portion 70. Without being limited thereto, for example, an opening is provided in each of the side plate portions 71, 72, and the engaging portion 61a enters the region 60a from the side plate portion 71, and the engaging portion 61b enters the region 60a from the side plate portion 72. Also good.

  However, if the engaging portions 61a and 61b are entered from the side plate portions 71 and 72 into the region 60a, the attachment member 61 is exposed to the outside. Accordingly, the engaging portions 61 a and 61 b of the attachment member 61 are caused to enter the region 60 a from the bottom plate portion 70. Thereby, it can suppress that the designability of the lighting fixture 10 is impaired, for example. Moreover, you may attach the attachment member 61 to the inner surface 70a, for example. That is, the attachment member 61 may be attached in the region 60a.

  Each of the end portion 71a of the side plate portion 71 and the end portion 72a of the side plate portion 72 is bent in a substantially U shape toward the inside. The end 71a and the end 72a are tapered so as to narrow the width (length in the width direction) of the region 60a. Thus, by making the end portion 71a and the end portion 72a into a tapered shape, for example, while securing a space for elastically deforming the attachment member 61 when releasing the engagement with the claw portions 51b and 52b, for example. Thus, it is possible to make it difficult to visually recognize the attachment member 61 and the like from the indoor side.

  The notch 71 b in which the notch 71 b is provided in the end 71 a is disposed at a position facing the engaging part 61 a of the attachment member 61. The notch 72 b in which the notch 72 b is provided in the end 72 a is disposed at a position facing the engaging portion 61 b of the attachment member 61. Each notch 71b, 72b is provided corresponding to each attachment member 61. In this example, three notches 71 b and 72 b are provided in the housing 60.

  In this example, the end portions 71a and 72a are bent in a substantially U shape, and the notches 71b and 72b are provided in the bent portions so that the end portions of the side plate portions 71 and 72 are not cut. ing. Thereby, for example, even when the notches 71b and 72b are provided, it is possible to suppress a decrease in the strength of the housing 60.

  For example, a rod-shaped jig is inserted into the notch 71b, the engaging part 61a of the attaching member 61 is pushed, and the attaching member 61 is elastically deformed so that the engaging part 61a is brought closer to the side plate part 71 side. Thereby, the engagement state of the 1st nail | claw part 51b and the engaging part 61a is cancelled | released.

  A rod-shaped jig is inserted into the notch 72b, the engagement portion 61b of the attachment member 61 is pushed, and the attachment member 61 is elastically deformed so that the engagement portion 61b is brought closer to the side plate portion 72 side. Thereby, the engagement state of the 2nd nail | claw part 52b and the engaging part 61b is cancelled | released.

  The regulating member 62 regulates the position in the width direction of the light source module 14 with respect to the mounting member 61. The regulating member 62 is attached to the bottom plate part 70. In this example, the regulating member 62 is attached to the outer surface 70b.

  The restricting member 62 includes a fourth extending part 62 a along the bottom plate part 70, a fifth extending part 62 b along the side plate part 71, and a sixth extending part 62 c along the side plate part 72. The regulating member 62 is, for example, a plate-like member that is bent into a substantially U shape. In this example, the fifth extending portion 62b enters the region 60a through the opening 70c. The sixth extending portion 62c enters the region 60a through the opening 70d.

  The restricting member 62 is attached on the outer surface 70b, for example. The attachment member 61 is attached on the restriction member 62. More specifically, the attachment member 61 is attached on the fourth extending portion 62 a of the restriction member 62. Thus, in the instrument main body 12, the attachment member 61 and the restriction member 62 can be attached to the housing 60 from the same outer surface 70 b side. Thereby, the assemblability of the lighting fixture 10 can be improved, for example. Note that the attachment member 61 and the restriction member 62 do not necessarily have to be attached in an overlapping manner. For example, the attachment member 61 and the restriction member 62 may be attached side by side on the outer surface 70b.

  The attachment member 61 and the restriction member 62 are attached to the bottom plate portion 70 by the same holding member 64. The holding member 64 is disposed, for example, near the center in the width direction of the attachment member 61 and the regulating member 62. The attachment member 61 and the restriction member 62 are attached to the bottom plate portion 70 near the center in the width direction. For the holding member 64, for example, a screw or a rivet is used.

  Thus, the restricting member 62 is provided corresponding to the mounting member 61, for example. In this example, three regulating members 62 are provided on the instrument body 12. Each restricting member 62 is attached to the housing 60 at a position corresponding to each holding member 23 and each attaching member 61 of the light source module 14. As described above, the instrument main body 12 includes the three attachment members 61 and the restriction members 62 disposed near both ends in the longitudinal direction and near the center in the longitudinal direction. Thereby, for example, the light source module 14 can be appropriately supported. It should be noted that the number of regulating members 62 is not necessarily the same as the number of mounting members 61.

FIG. 7 is a schematic diagram illustrating a part of the lighting apparatus according to the first embodiment.
As illustrated in FIGS. 6 and 7, the fifth extending portion 62 b faces at least a part of the light source module 14 in the width direction. For example, the fifth extending portion 62b faces the first grip 51 in the width direction. A cutout 62d for inserting the engaging portion 61a is provided at the end of the fifth extending portion 62b. For example, the fifth extending portion 62b faces the first claw portion 51b at both sides of the notch 62d.

  The sixth extending portion 62c faces at least a part of the light source module 14 in the width direction. For example, the sixth extending part 62c faces the second grip part 52 in the width direction. A cutout 62e for inserting the engaging portion 61b is provided at the end of the sixth extending portion 62c. For example, the sixth extending portion 62c faces the second claw portion 52b at both sides of the notch 62e.

  Is the distance in the width direction between the fifth extension part 62b and the sixth extension part 62c substantially the same as the distance in the width direction between the first claw part 51b and the second claw part 52b, for example? A little longer. That is, the restricting member 62 sandwiches the portion between the claw portions 51b and 52b of the light source module 14 by the extending portions 62b and 62c. The distance between the 5th extension part 62b and the 1st nail | claw part 51b is shorter than the overlap amount (length of the engaged part) of the engaging part 61a and the 1st nail | claw part 51b in the width direction. . The distance between the sixth extending portion 62c and the second claw portion 52b is shorter than the overlapping amount in the width direction between the engaging portion 61b and the second claw portion 52b.

  For example, when the light source module 14 moves in the width direction due to an external force or the like, the claw portions 51b and 52b come into contact with the extending portions 62b and 62c. Thereby, the position of the light source module 14 in the width direction is regulated by the regulating member 62. For example, the displacement of the light source module 14 in the width direction is suppressed by the restriction member 62.

FIG. 8 is a plan view schematically showing a part of the lighting fixture according to the first embodiment.
As shown in FIGS. 6 to 8, the restricting member 62 is provided with a protrusion 65. The protruding portion 65 is provided on the fourth extending portion 62a facing the outer surface 70b. The protruding portion 65 protrudes from the fourth extending portion 62a in the direction opposite to the region 60a. The restricting member 62 has, for example, a plurality of protrusions 65. In this example, four protrusions 65 arranged in the longitudinal direction and in the width direction are provided on the regulating member 62. The number of the protrusions 65 may be arbitrary. One protrusion 65 may be provided. In this example, the protrusion 65 is hemispherical. The shape of the protrusion 65 is not limited to a hemispherical shape, and may be any shape that protrudes in the direction opposite to the region 60a. The protrusion 65 is formed by, for example, pressing.

  For example, when the lighting device 10 is installed on the ceiling, each protrusion 65 contacts the ceiling surface and forms a predetermined gap between the ceiling surface and the outer surface 70b. Accordingly, for example, when the instrument body 12 is screwed to the ceiling surface, it is possible to prevent the cable body or the screw head from being sandwiched between the ceiling surface and the outer surface 70b and the instrument body 12 from being deformed. .

  Each protrusion 65 is disposed in the vicinity of the attachment member 61. The distance D1 in the longitudinal direction between the protrusion 65 and the attachment member 61 is, for example, 30 mm or less. That is, “in the vicinity of the attachment member 61” means that the distance D1 is 30 mm or less.

  When the instrument main body 12 is screwed to a ceiling board or the like, for example, the case 60 may be deformed by tightening the screws too much. When the housing 60 is deformed when the mounting member 61 is engaged to support the light source module 14, for example, the positions of the mounting member 61 and the claws 51b and 52b are shifted. Thereby, it becomes difficult to attach or remove the light source module 14 with respect to the instrument body 12.

  By providing the protrusion 65 in the vicinity of the attachment member 61, deformation of the housing 60 in the vicinity of the attachment member 61 can be suppressed. For example, the light source module 14 can be easily attached to and detached from the instrument body 12. For example, it is possible to easily attach the instrument main body 12 to an attachment target such as a ceiling.

  In this example, the attachment member 61 is disposed between the two protrusions 65 arranged in the longitudinal direction. Thereby, for example, the deformation of the housing 60 in the vicinity of the attachment member 61 can be more appropriately suppressed.

  The bottom plate portion 70 is provided with a protrusion 66. The protrusion 66 protrudes from the outer surface 70b in the direction opposite to the region 60a. The protrusion 66 is formed by, for example, pressing. The shape of the protrusion 66 may be any shape. For example, the bottom plate 70 is provided with a plurality of protrusions 66. Each protrusion 66 is disposed, for example, in the vicinity of the end of the bottom plate 70 in the longitudinal direction.

  The position of the apex in the height direction of each protrusion 66 is substantially the same as the position of the apex in the height direction of each protrusion 65 (see FIG. 6). Thereby, when each protrusion 65 contacts the ceiling surface or the like, each protrusion 66 also contacts the ceiling surface or the like. Thereby, the deformation | transformation in the edge part vicinity of the longitudinal direction of the housing | casing 60 at the time of installing the lighting fixture 10 on a ceiling etc. can be suppressed, for example. For example, warpage in the longitudinal direction of the housing 60 can be suppressed.

  A distance D2 in the longitudinal direction between the end portion in the longitudinal direction of the bottom plate portion 70 and the protrusion 66 is, for example, 10 cm or less. Thereby, the deformation | transformation in the edge part vicinity of the longitudinal direction of the housing | casing 60 can be suppressed appropriately.

  For the housing 60, for example, a metal material such as iron, aluminum, or stainless steel is used. For the mounting member 61 and the regulating member 62, for example, the same metal material as described above is used. The attachment member 61 has elasticity. The attachment member 61 is, for example, an attachment spring. More specifically, it is a leaf spring. The strength of the restricting member 62 is higher than the strength of the mounting member 61. For example, the elastic coefficient of the restricting member 62 is higher than the elastic coefficient of the mounting member 61. In the restricting member 62, for example, the deformation of the extending portions 62b and 62c when an external force in the width direction is applied is reduced. Thereby, for example, the position of the light source module 14 in the width direction can be appropriately regulated. For example, a resin material may be used for the housing 60, the attachment member 61, and the restriction member 62. However, by using a metal material for the housing 60, the mounting member 61, and the regulating member 62, for example, the durability of these can be improved.

  When the lighting fixture 10 is installed on the ceiling, for example, the fixture body 12 is screwed to the ceiling board or the like from the indoor side in a state where the projections 65 and 66 are in contact with the ceiling surface.

  The instrument body 12 is provided with, for example, at least two chains (not shown) for suppressing the light source module 14 from dropping. For example, two chains are provided near both ends in the longitudinal direction. For example, a plurality of hooks corresponding to each chain are provided on the back surface 31 b of the support 21 of the light source module 14. After the fixture body 12 is screwed to the ceiling, the end of each chain is hooked on the hook of the light source module 14 to hang the light source module 14.

  After the light source module 14 is suspended, the light source module 14 and the power supply device 15 are electrically connected, for example, by connecting a connector (not shown).

  After wiring, with the light source module 14 tilted in the longitudinal direction, the second portion 32 side of the support 21 is placed in the region 60a, and each first claw portion 51b of each holding member 23 is attached to each mounting member 61. Are engaged with the respective engaging portions 61a. Thereafter, the third portion 33 side of the support 21 is placed in the region 60 a so that the light source module 14 is returned to the horizontal position, and the second claw portions 52 b of the holding members 23 are respectively connected to the mounting members 61. Engage with the engaging portion 61b.

  Thereby, the light source module 14 is supported by the fixture main body 12, and the lighting fixture 10 is attached to a ceiling. In addition, contrary to the above, after engaging each 2nd nail | claw part 52b with each engaging part 61b, you may engage each 1st nail | claw part 51b with each engaging part 61a.

  For example, in a lighting fixture that does not have the regulating member 62, when an external force in the width direction is applied to the light source module or the fixture body, the housing may be deformed and the light source module may move in the width direction. is there. When the light source module moves in the width direction, the engagement state between the mounting member and the light source module is released, and the light source module is unintentionally detached from the instrument body.

  On the other hand, in the lighting fixture 10 according to the present embodiment, the position in the width direction of the light source module 14 is regulated by the regulating member 62. Thereby, in the lighting fixture 10 which concerns on this embodiment, when the external force of the width direction is added with respect to the light source module, it can suppress that the light source module 14 moves to the width direction, for example. Therefore, it can suppress that the light source module 14 remove | deviates from the instrument main body 12 unintentionally.

  Further, for example, there is a luminaire in which a protrusion is provided on a bottom plate (housing) in the vicinity of an attachment member. In this case, for example, it becomes difficult to manage the dimensions of the housing. For example, the error of the attachment position of the attachment member becomes large. For this reason, for example, the yield of a housing | casing will fall.

  On the other hand, in the lighting fixture 10 according to the present embodiment, the restricting member 62 is provided with the protrusion 65. Thereby, for example, the dimensional accuracy of the housing 60 can be increased. For example, the yield of the housing 60 can be improved. For example, the manufacturing cost of the lighting fixture 10 can be reduced.

  Furthermore, in the lighting fixture 10 according to the present embodiment, the attachment member 61 and the restriction member 62 can be attached to the housing 60 from the same direction. Thereby, for example, the workability of assembling the attachment member 61 and the regulating member 62 can be improved.

  When removing the light source module 14 from the instrument main body 12, for example, after each engagement state between each first claw portion 51b and each engagement portion 61a is released, each second claw portion 52b and each engagement portion are released. Each engagement state with 61b is cancelled | released. On the contrary, after each engagement state between each second claw portion 42b and each end portion 114b is released, each engagement state between each first claw portion 41b and each end portion 114a may be released. .

FIG. 9 is a partial cross-sectional view schematically showing a part of the lighting apparatus according to the first embodiment.
As described above, the attachment member 61 is attached to the outer surface 70b near the center in the width direction. Further, in the lighting fixture 10, a gap is formed between the outer surface 70 b and the mounting surface (for example, the ceiling surface) by the protrusions 65 and 66.

  Thereby, in the lighting fixture 10, as shown in FIG. 9, when the jig is inserted into the notch 71b, the engaging portion 61a of the mounting member 61 is pushed, and the mounting member 61 is elastically deformed, A part of the member 61 can be separated from the outer surface 70b. A part of the attachment member 61 can be moved to the attachment surface side.

  Thereby, for example, the engagement between the first claw portion 51b and the engaging portion 61a can be easily released. In other words, the operability of releasing the engagement can be improved. Further, when releasing the engagement between the first claw portion 51b and the engaging portion 61a, by moving a part of the attachment member 61 to the attachment surface side, for example, the engagement necessary for releasing the engagement The amount of movement of the portion 61a toward the side plate portion 71 can be reduced. Therefore, for example, the distance in the width direction between the engaging portion 61a and the side plate portion 71 can be shortened as compared with the case where the mounting member 61 cannot move to the mounting surface side. For example, the width of the housing 60 can be made narrower.

FIG. 10A to FIG. 10C are plan views schematically showing a part of the lighting fixture according to the first embodiment.
As shown in FIG. 10A, the mounting member 61 may be provided with a protrusion 67. The shape of the protrusion 67 and the number of the protrusions 67 may be arbitrary. The position of the apex in the height direction of the protrusion 67 is, for example, substantially the same as the position of the apex in the height direction of the protrusion 65 and the position of the apex in the height direction of the protrusion 66. Thereby, for example, deformation of the housing 60 can be further suppressed.

  As shown in FIG. 10B, the protrusion 67 may be provided only on the attachment member 61. As described above, the protrusion may be provided on at least one of the attachment member 61 and the regulating member 62.

  As shown in FIG. 10C, the attachment member 61 and the restriction member 62 are disposed in the vicinity of the end portion in the longitudinal direction of the housing 60, and a protrusion is provided on at least one of the attachment member 61 and the restriction member 62. It may be provided. For example, the distance D3 in the longitudinal direction between the end portion in the longitudinal direction of the housing 60 and the projecting portion 65 (or the projecting portion 67) is set to 10 cm or less. Thereby, for example, it is not necessary to provide the protrusion 66 on the housing 60. Thereby, for example, the yield of the housing 60 can be further increased.

(Second Embodiment)
FIG. 11 is a cross-sectional view schematically illustrating a lighting fixture according to the second embodiment.
As shown in FIG. 11, in the lighting fixture 100, the regulating member 102 is attached on the inner surface 70 a.

The regulating member 102 is, for example, a plate-like member that is bent into a substantially M shape.

  The eighth extending portion 102b faces at least a part of the light source module 14 in the width direction. For example, the eighth extending portion 102b faces the first grip 51 in the width direction. The ninth extending portion 102c faces at least a part of the light source module 14 in the width direction. For example, the ninth extending portion 102c faces the second grip portion 52 in the width direction.

  The distance in the width direction between the eighth extension portion 102b and the ninth extension portion 102c is substantially the same as the distance in the width direction between the inner portions of the first grip portion 51 and the second grip portion 52, for example. Or slightly narrower. In the restricting member 102, the extending portions 102 b and 102 c enter between the gripping portions 51 and 52.

  The distance between the eighth extending portion 102b and the first gripping portion 51 is shorter than the overlapping amount in the width direction between the engaging portion 61a and the first claw portion 51b. The distance between the ninth extending portion 102c and the second grip portion 52 is shorter than the overlapping amount in the width direction between the engaging portion 61b and the second claw portion 52b.

  In the restricting member 102, when the light source module 14 is moved in the width direction by an external force or the like, the grip portions 51 and 52 abut against the extension portions 102b and 102c. Thereby, the position of the light source module 14 in the width direction can also be regulated by the regulating member 102. As described above, the regulating member 102 may be attached on the inner surface 70 a of the bottom plate part 70.

  The attachment member 61 and the restriction member 102 are attached to the bottom plate portion 70 by the same holding member 64. The holding member 64 is disposed, for example, near the center in the width direction of the attachment member 61 and the regulating member 102. The attachment member 61 and the regulating member 102 are attached to the bottom plate portion 70 near the center in the width direction.

  However, as shown in the first embodiment, the regulating member 62 is attached on the outer surface 70b. Thereby, for example, the attachment member 61 and the regulating member 62 can be attached to the bottom plate portion 70 from the same direction, and the attachment workability can be improved. Moreover, the protrusion 65 can be provided in the control member 62, and the yield of the housing | casing 60 can be improved.
