As illustrated in FIGS. 1 to 4, the light source module 10 includes a support 11, a cover 12, and a holding member 13.

  The support 11 supports the substrate 15. The substrate 15 may be fixed to the support 11 by bonding or the like, or may be detachably attached to the support 11 by screwing or the like. The support 11 may support the substrate 15 in a detachable manner.

  A light source 16 is provided on the substrate 15. For example, the substrate 15 is provided with a plurality of light sources 16. Each light source 16 is arranged side by side on the surface 15 a of the substrate 15. The number of the light sources 16 may be arbitrary. The number of light sources 16 may be one, for example.

  For example, a light emitting diode (LED) is used as the light source 16. The light source 16 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 16 may be a light bulb, for example.

  The cover 12 is attached to the support 11 and covers the substrate 15 supported by the support 11. The cover 12 protects the substrate 15 and each light source 16 from, for example, external force or dust. The cover 12 is light transmissive. The cover 12 is light transmissive with respect to the light emitted from each light source 16. The cover 12 is transparent, for example. The cover 12 may have light diffusibility, for example. For the cover 12, for example, a light transmissive resin material is used.

  The holding member 13 holds the cover 12 on the support 11. That is, the holding member 13 prevents the cover 12 from being detached from the support body 11. For example, the light source module 10 is provided with a plurality of holding members 13. In this example, three holding members 13 are provided. The number of holding members 13 may be arbitrary. For example, the number of the holding members 13 may be one or two, or may be four or more.

  The support 11 includes a first portion 21, a second portion 22, and a third portion 23. The first portion 21 has a first surface 21a extending in the first direction and a second surface 21b opposite to the first surface 21a. The first portion 21 has a plate shape. The first portion 21 is, for example, a long plate that is long in the first direction. In this example, the first surface 21a and the second surface 21b are substantially rectangular. The shape of the first surface 21a and the shape of the second surface 21b are not limited to a rectangular shape, and may be any shape extending in the first direction. In this example, the second surface 21b is substantially parallel to the first surface 21a.

  Here, a direction parallel to the first direction is defined as an X-axis direction. A direction parallel to the first surface 21a and perpendicular to the X-axis direction is taken as a Y-axis direction. A direction perpendicular to the X-axis direction and the Y-axis direction is taken as a Z-axis direction. The Z-axis direction is a direction perpendicular to the first surface 21a.

  The second portion 22 is provided at one side end 21p extending in the X-axis direction of the second surface 21b. The second portion 22 extends in the direction facing the second surface 21b. In other words, the second portion 22 extends in a direction from the first surface 21a toward the second surface 21b.

  The third portion 23 is provided on the other side end 21q extending in the X-axis direction of the second surface 21b. The second portion 22 extends in the direction facing the second surface 21b.

  In this example, the shape of the support 11 viewed in the X-axis direction is substantially U-shaped. The second portion 22 and the third portion 23 are so-called ribs. The shape of the support 11 viewed in the X-axis direction may be, for example, an H shape. That is, the second portion 22 and the third portion 23 only need to extend at least in the direction toward the second surface 21b, and may further extend in the direction toward the first surface 21a. In this example, the second portion 22 and the third portion 23 extend in a direction substantially perpendicular to the second surface 21b. The second portion 22 and the third portion 23 may be inclined with respect to the second surface 21b. For the support 11, for example, a metal material such as iron, aluminum, or stainless steel is used. The support 11 is formed, for example, by bending a metal plate.

  In this example, the support 11 is provided with one second portion 22 extending in the X-axis direction along one side end 21p of the second surface 21b. One third portion 23 extending in the X-axis direction is provided along the other side end 21q of the second surface 21b. For example, a plurality of second portions 22 arranged in the X-axis direction may be provided, or a plurality of third portions 23 arranged in the X-axis direction may be provided.

  The support 11 supports the substrate 15 with the first surface 21a. The substrate 15 is provided on the first surface 21a. The support 11 supports the substrate 15 with the front surface 15a of the substrate 15 facing the first surface 21a. Thereby, light is irradiated to the direction which the 1st surface 21a faces.

  Further, the length (width) of the first surface 21 a in the Y-axis direction is longer than the length of the substrate 15 in the Y-axis direction. For this reason, one end portion 21m extending in the X-axis direction of the first surface 21a and the other end portion 21n extending in the X-axis direction of the first surface 21a are formed on the substrate 15 even when the substrate 15 is supported. Not covered.

  The cover 12 includes a main body portion 30, a first contact portion 31, a second contact portion 32, a first engagement portion 33, and a second engagement portion 34.

  The main body 30 faces the first surface 21a and covers the substrate 15 supported by the first surface 21a. The main body portion 30 includes, for example, a first plate portion 30a facing the first surface 21a, a second plate portion 30b extending in the Z-axis direction from one end of the first plate portion 30a in the Y-axis direction, and a first plate portion 30a. A third plate portion 30c extending in the Z-axis direction from the other end in the Y-axis direction.

  In this example, the second plate portion 30b and the third plate portion 30c are inclined with respect to the XZ plane. The distance in the Y-axis direction between the second plate portion 30b and the third plate portion 30c becomes longer in the light irradiation direction. The distance in the Y-axis direction between the second plate portion 30b and the third plate portion 30c is, for example, continuously longer in the light irradiation direction. That is, the second plate portion 30b and the third plate portion 30c are tapered. The shape of the main body 30 viewed in the X-axis direction is, for example, a fan shape. Thereby, for example, when the light source module 10 is installed on the ceiling, the ceiling surface can be efficiently illuminated by the light emitted from the second plate portion 30b and the third plate portion 30c.

  The first contact portion 31 is provided at one end of the main body portion 30 in the Y-axis direction. The 1st contact part 31 is provided in the edge part on the opposite side to the 1st board part 30a of the 2nd board part 30b, for example. The first contact portion 31 contacts one side end 21m of the first surface 21a.

  The second contact portion 32 is provided at the other end of the main body portion 30 in the Y-axis direction. The second contact portion 32 is provided, for example, at an end portion of the third plate portion 30c opposite to the first plate portion 30a. The second contact portion 32 contacts the other side end 21n of the first surface 21a.

  In this example, the first contact portion 31 and the second contact portion 32 are in direct contact with the first surface 21a. The 1st contact part 31 and the 2nd contact part 32 do not necessarily need to contact the 1st surface 21a directly. The first contact portion 31 and the second contact portion 32 may contact the first surface 21a with another member interposed therebetween.

  The first engaging portion 33 is provided at one end of the main body portion 30 in the Y-axis direction. The first engagement portion 33 engages with the end portion 22 a of the second portion 22 in the Z-axis direction, and sandwiches the second portion 22 together with the first contact portion 31. For example, the first engagement portion 33 covers the second portion 22 from the outside.

  The second engagement portion 34 is provided at the other end of the main body portion 30 in the Y-axis direction. The second engagement portion 34 engages with the end portion 23 a of the third portion 23 in the Z-axis direction, and sandwiches the third portion 23 together with the second contact portion 32. For example, the second engaging portion 34 covers the third portion 23 from the outside.

  Thus, the cover 12 covers the support 11 from the first surface 21 a side, and engages the engaging portions 33 and 34 with the second portion 22 and the third portion 23. As a result, the cover 12 is attached to the support 11.

  The light source module 10 further includes a pair of side plates 17 and 18. The side plate 17 is attached to one end of the support 11 and the cover 12 in the X-axis direction. The side plate 18 is attached to the other end of the support 11 and the cover 12 in the X-axis direction. The side plate 17 closes one end of the cover 12 in the X-axis direction. The side plate 18 closes the other end of the cover 12 in the X-axis direction.

  The holding member 13 includes a facing portion 40, a first grip portion 41, and a second grip portion 42. The facing portion 40 faces the second surface 21b. The facing portion 40 is in contact with the second surface 21b, for example. The length of the facing portion 40 in the Y-axis direction is substantially the same as or slightly shorter than the length of the second surface 21b in the Y-axis direction.

  The first grip portion 41 is provided at one end of the facing portion 40 in the Y-axis direction. The first grip portion 41 grips the second portion 22 and the first engagement portion 33 between them. The first grip 41 is, for example, a leaf spring, and suppresses the engagement of the first engagement portion 33 from being released by sandwiching the second portion 22 and the first engagement portion 33. .

  The second grip portion 42 is provided at the other end of the facing portion 40 in the Y-axis direction. The second grip portion 42 grips the third portion 23 and the second engagement portion 34 between them. The second grip portion 42 is, for example, a leaf spring, and suppresses the engagement of the second engagement portion 34 from being released by sandwiching the third portion 23 and the second engagement portion 34. . In other words, the holding member 13 suppresses the opening of the cover 12 by being sandwiched between the gripping portions 41 and 42.

  As described above, the holding member 13 is attached to the support 11 from the second surface 21b side, sandwiches the second portion 22 and the first engaging portion 33 with the first grip portion 41, and connects the third portion 23 and the second portion. The cover 12 is held on the support 11 by sandwiching the engaging portion 34 with the second grip portion 42.

  The first grip portion 41 is provided with a first stopper portion 43. The first stopper portion 43 engages with the first engaged portion 22b provided in the second portion 22 and faces the second surface 21b of the first grip portion 41 (a direction away from the second surface 21b). ) Is restricted.

  The second grip portion 42 is provided with a second stopper portion 44. The second stopper portion 44 engages with the second engaged portion 23 b provided in the third portion 23, and restricts the movement of the second grip portion 42 in the direction toward the second surface 21 b.

  Each stopper part 43 and 44 is engaged in the state which made the opposing part 40 contact the 2nd surface 21b. Thereby, the holding member 13 is held by the support 11. The holding member 13 is prevented from being detached from the support 11. Therefore, the cover 12 is appropriately held by the support 11.

  In this example, three holding members 13 are attached to the support 11. Therefore, three first engaged portions 22b are provided in the second portion 22 side by side in the X-axis direction. In the third portion 23, three second engaged portions 23b are provided side by side in the X-axis direction. For example, the position where the first engaged portion 22 b and the second engaged portion 23 b are provided is the attachment position of the holding member 13.

  In this example, the first stopper portion 43 and the second stopper portion 44 are substantially hemispherical protrusions protruding outward, and the first engaged portion 22b and the second engaged portion 23b are substantially rectangular. It is a through-hole of shape. On the other hand, the first stopper portion 43 and the second stopper portion 44 may be through holes, and the first engaged portion 22b and the second engaged portion 23b may be protrusions. Each shape of the 1st stopper part 43, the 2nd stopper part 44, the 1st to-be-engaged part 22b, and the 2nd to-be-engaged part 23b may be arbitrary shapes which can suppress the detachment | leave of the holding member 13. FIG.

  In this example, two first stopper portions 43 and two second stopper portions 44 are provided side by side in the X-axis direction. The number of each of the first stopper portion 43 and the second stopper portion 44 is arbitrary. Each of the 1st stopper part 43 and the 2nd stopper part 44 may be one, and may be three or more.

  The first holding part 41 is provided with a pair of holding parts 41a and a first claw part 41b. The holding parts 41a are provided side by side in the X-axis direction. Each holding portion 41 a is a portion that is bent into a substantially U shape and sandwiches the second portion 22 and the first engaging portion 33. The 1st nail | claw part 41b is provided between each holding | suppressing part 41a. The first claw portion 41b protrudes in the direction substantially parallel to the second surface 21b in the direction opposite to the facing portion 40. For example, the first claw portion 41b protrudes outward in the Y-axis direction.

  The second grip portion 42 is provided with a pair of holding portions 42a and a second claw portion 42b. Each holding portion 42a is provided side by side in the X-axis direction. Each holding portion 42 a is a portion that is bent into a substantially U shape and sandwiches the third portion 23 and the second engaging portion 34. The 2nd nail | claw part 42b is provided between each holding | suppressing part 42a. The 2nd nail | claw part 42b protrudes toward the direction opposite to the opposing part 40 in the direction substantially parallel to the 2nd surface 21b. For example, the second claw portion 42b protrudes outward in the Y-axis direction.

  Each nail | claw part 41b, 42b is used for the attachment to the instrument main body of the light source module 10. FIG. As described above, the holding member 13 is used for holding the cover 12 and also for attaching the light source module 10 to the instrument body.

  For the holding member 13, for example, a metal material such as iron, aluminum, or stainless steel is used. For the holding member 13, for example, a resin material or the like may be used. However, it is preferable to use the metal material as described above for the holding member 13. Thereby, the durability of the holding member 13 can be improved, for example. Further, the holding member 13 is formed 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 10 can be suppressed. For example, when a resin material is used for the holding member 13, the holding member 13 is preferably a single part formed by injection molding or the like.

  Some light source modules have a cover screwed to a support. In such a light source module, a tool is required at the time of assembly, and the assembly becomes complicated.

  On the other hand, in the light source module 10 according to the present embodiment, after the substrate 15 is supported by the support 11, the engagement portions 33 and 34 are engaged to attach the cover 12 to the support 11, and the holding member 13, the cover 12 is held on the support 11. Then, the side plate 17 closes one end of the cover 12 in the X-axis direction, and the side plate 18 closes the other end of the cover 12 in the X-axis direction. Thereby, the light source module 10 is assembled.

  Thus, the light source module 10 according to the present embodiment can be assembled without using a tool or the like. Therefore, in the light source module 10, assemblability can be improved compared to 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 10 can be reduced.

(Second Embodiment)
FIG. 5A and FIG. 5B are perspective views schematically showing a lighting fixture according to the second embodiment.
FIG. 6 is a cross-sectional view schematically illustrating a lighting fixture according to the second embodiment.
FIG. 7 is a plan view schematically showing a part of the lighting fixture according to the second embodiment.
As illustrated in FIGS. 5 to 7, the lighting fixture 100 includes the light source module 10 described in the first embodiment and the fixture main body 110 that supports the light source module 10.

  The luminaire 100 is attached to the ceiling of the room with the light source module 10 facing downward, for example. The lighting fixture 100 illuminates the room with light emitted from the light source module 10. The lighting fixture 100 is not limited to the ceiling, and may be attached to, for example, a wall surface. The instrument body 110 is attached to the ceiling with screws or the like, for example. Thus, the fixture body 110 is used for supporting the light source module 10 and for attaching the lighting fixture 100 to an attachment target such as a ceiling.

  The instrument body 110 includes, for example, a housing 112 and an attachment spring 114. The housing 112 is provided with a recess 112 a that houses at least a part of the light source module 10. The attachment spring 114 is attached to the housing 112. The attachment spring 114 engages with the first claw portion 41b and the second claw portion 42b of the light source module 10 accommodated in the recess 112a, and restricts the movement of the light source module 10 in the direction of coming out of the recess 112a.

  Thus, the instrument main body 110 supports the light source module 10 by engaging the attachment spring 114 with each claw part 41b and 42b. In this example, the light source module 10 is provided with three holding members 13. For this reason, in this example, the three attachment springs 114 are provided in the instrument main body 110. Each attachment spring 114 is attached to the housing 112 at a position corresponding to each holding member 13 of the light source module 10. The instrument main body 110 supports the light source module 10 by engaging the attachment springs 114 with the respective claw portions 41 b and 42 b of the holding members 13.

  For the housing 112, for example, a metal material such as iron, aluminum, or stainless steel is used. For the attachment spring 114, for example, the same metal material as described above is used. The attachment spring 114 has elasticity. The attachment spring 114 is a so-called leaf spring. For the housing 112 and the attachment spring 114, for example, a resin material or the like may be used. However, by using a metal material for the housing 112 and the mounting spring 114, for example, the durability thereof can be improved.

  The instrument main body 110 is further provided with, for example, a power supply circuit 115 and terminal blocks 116 and 117. The power supply circuit 115 and the terminal blocks 116 and 117 are attached in the recess 112a by, for example, screwing.

  For example, the power supply circuit 115 converts electric power supplied from the outside into a voltage or current corresponding to the light source module 10 and supplies the converted voltage or current to the light source module 10. The light source module 10 turns on the light source 16 according to the power supply from the power supply circuit 115 and irradiates light. The power supply circuit 115 may be provided separately from the lighting fixture 100, for example.

  The terminal blocks 116 and 117 are used for, for example, an electrical connection between an external power supply and the power supply circuit 115, an electrical connection between the power supply circuit 115 and each light source 16, and the like.

  In addition, the housing 112 is provided with a plurality of openings for passing, for example, metal fittings (for example, screws) for attaching the lighting fixture 100 to a ceiling or the like, a power supply cable for supplying power to the power supply circuit 115, and the like.

  The housing 112 includes, for example, a bottom plate portion 120, a first side plate portion 121, a second side plate portion 122, a first inclined plate portion 123, and a second inclined plate portion 124.

  The bottom plate part 120 has a third surface 120a that faces the second surface 21b, and a fourth surface 120b opposite to the third surface 120a. For example, the third surface 120a faces the entire second surface 21b. The bottom plate portion 120 is also a long plate extending in the X-axis direction. In this example, the fourth surface 120b is substantially parallel to the third surface 120a. The fourth surface 120b may be non-parallel to the third surface 120a. In this example, the third surface 120a is substantially parallel to the second surface 21b. The third surface 120a may be non-parallel to the second surface 21b. The power supply circuit 115 and the terminal blocks 116 and 117 are attached to the third surface 120a, for example.

  The first side plate portion 121 extends from one side end of the third surface 120a extending in the X-axis direction in the direction toward the third surface 120a, and faces the first grip portion 41 in the Y-axis direction. The second side plate portion 122 extends from the other side end of the third surface 120a extending in the X-axis direction in the direction toward the third surface 120a, and faces the second grip portion 42 in the Y-axis direction. That is, the recess 112 a is formed by the bottom plate portion 120 and the side plate portions 121 and 122.

  In this example, the first side plate portion 121 and the second side plate portion 122 extend in a direction substantially perpendicular to the third surface 120a. That is, in this example, the first side plate portion 121 and the second side plate portion 122 extend in the Z-axis direction. The first side plate portion 121 and the second side plate portion 122 may be inclined with respect to the third surface 120a.

  One end of the first inclined plate portion 123 is connected to the end portion of the first side plate portion 121 opposite to the bottom plate portion 120. The first inclined plate portion 123 extends obliquely from the end portion of the first side plate portion 121 on the opposite side to the bottom plate portion 120 toward the fourth surface 120b. One end of the second inclined plate portion 124 is connected to the end portion of the second side plate portion 122 opposite to the bottom plate portion 120. The second inclined plate portion 124 extends obliquely from the end of the second side plate portion 122 opposite to the bottom plate portion 120 toward the fourth surface 120b. The distance in the Y-axis direction between the second inclined plate portion 123 and the second inclined plate portion 124 decreases in the direction in which the third surface 120a faces. That is, the second inclined plate portion 123 and the second inclined plate portion 124 have a substantially trapezoidal shape when viewed in the X-axis direction of the housing 112.

  The end portion 123a of the first inclined plate portion 123 is bent toward the first side plate portion 121 so as to be substantially parallel to the third surface 120a. Further, the end portion 123a of the first inclined plate portion 123 is disposed at a position protruding in the direction in which the fourth surface 120b faces the fourth surface 120b.

  The end portion 124a of the second inclined plate portion 124 is bent toward the second side plate portion 122 so as to be substantially parallel to the third surface 120a. Further, the end portion 124a of the second inclined plate portion 124 is disposed at a position protruding in the direction in which the fourth surface 120b faces the fourth surface 120b.

  The distance in the Z-axis direction between the end portion 123a of the first inclined plate portion 123 and the fourth surface 120b is the distance in the Z-axis direction between the end portion 124a of the second inclined plate portion 124 and the fourth surface 120b. Is substantially the same. That is, the end 123a is substantially flush with the end 124a.

  Thereby, when installing the lighting fixture 100 on a ceiling, the edge parts 123a and 124a contact | abut on a ceiling surface, for example. The third surface 120a is substantially parallel to the ceiling surface. At this time, the fourth surface 120b is slightly separated from the ceiling surface. Thereby, for example, a screw or the like for attaching each component such as the power supply circuit 115 to the housing 112 can be prevented from contacting the ceiling surface.

  The first side plate portion 121 is provided with an opening 121a. The opening 121a is disposed at a position facing the first grip portion 41 in the Y-axis direction. The second side plate portion 122 is provided with an opening 122a. The opening 122a is disposed at a position facing the second grip portion 42 in the Y-axis direction. In this example, three openings 121a and three openings 122a are provided for each of the three holding members 13 of the light source module 10.

  The attachment spring 114 is attached to the bottom plate part 120. In this example, the attachment spring 114 is attached to the fourth surface 120b. That is, the attachment spring 114 is attached to the outside of the recess 112a. The attachment spring 114 is attached to the fourth surface 120b with, for example, a screw or a rivet. The attachment spring 114 is bent in a substantially U shape, and has a portion along the bottom plate portion 120, a portion along the first side plate portion 121, and a portion along the second side plate portion 122.

  One end 114a of the attachment spring 114 is bent into a substantially U shape and enters the recess 112a through the opening 121a. This end 114a engages with the first claw portion 41b of the light source module 10 accommodated in the recess 112a.

  The other end 114b of the attachment spring 114 is bent into a substantially U shape and enters the recess 112a through the opening 122a. This end 114b engages with the second claw 42b of the light source module 10 accommodated in the recess 112a.

  In this example, the attachment spring 114 has an end portion 114a that engages with the first claw portion 41b and an end portion 114b that engages with the second claw portion 42b. For example, the mounting spring 114 may be composed of two parts: a part having an end part that engages with the first claw part 41b and another part having an end part that engages with the second claw part 42b. Good.

  The housing 112 is provided with an opening 112b and an opening 112c. The opening 112b is disposed at a position facing the end portion 114a of the mounting spring 114 in the Z-axis direction. The opening 112c is disposed at a position facing the end 114b of the mounting spring 114 in the Z-axis direction. Each opening 112b, 112c is provided corresponding to each attachment spring 114. In this example, three openings 112 b and three openings 112 c are provided in the housing 112.

  A rod-shaped jig is inserted into the opening 112b and the end 114a of the mounting spring 114 is pushed to elastically deform the mounting spring 114. Then, along the inclination of the end portion 114a, the end portion 114a moves in a direction to retract from the recess 112a, and the engagement state between the first claw portion 41b and the end portion 114a is released.

  A rod-shaped jig is inserted into the opening 112c, and the end 114b of the mounting spring 114 is pushed, so that the mounting spring 114 is elastically deformed. Then, along the inclination of the end portion 114b, the end portion 114b moves in a direction to retract from the recess 112a, and the engagement state between the second claw portion 42b and the end portion 114b is released.

  Thus, the instrument main body 110 detachably supports the light source module 10 by engaging the attachment spring 114 and releasing the engagement state.

  As described above, in the cover 12 of the light source module 10, the shape of the main body 30 viewed in the X-axis direction is a fan shape. The openings 112b and 112c of the housing 112 overlap the main body 30 in the Z-axis direction. Thereby, for example, when viewed from the indoor side, the openings 112b and 112c can be made difficult to visually recognize. For example, the designability of the lighting fixture 100 can be improved.

  As shown in FIGS. 6 and 7, the fourth surface 120 b is provided with a protrusion 126. For example, a plurality of protrusions 126 are provided on the fourth surface 120b. The number of the protrusions 126 may be arbitrary. One protrusion 126 may be provided. In this example, the protrusion 126 is hemispherical. The shape of the protrusion 126 is not limited to a hemispherical shape, and may be any shape protruding in the direction in which the fourth surface 120b faces.

  The height of the protrusion 126 (the length in the Z-axis direction from the fourth surface 120b) is substantially the same as the distance in the Z-axis direction between the fourth surface 120b and the end portion 123a (end portion 124a). is there. Thereby, for example, when the end portions 123a and 124a are brought into contact with the ceiling surface, the protrusion 126 contacts the ceiling surface together with the end portions 123a and 124a.

  The protrusion 126 is disposed in the vicinity of the attachment spring 114. A distance D1 in the X-axis direction between the protrusion 126 and the attachment spring 114 is, for example, 30 mm or less. That is, “near the mounting spring 114” means that the distance D1 is 30 mm or less. In this example, a plurality of protrusions 126 are arranged on both sides in the X-axis direction with the attachment spring 114 interposed therebetween. The protrusion 126 may be provided only on one side of the attachment spring 114 in the X-axis direction.

  When the lighting fixture 100 is installed on the ceiling, the fixture main body 110 is screwed to the ceiling plate or the like from the indoor side with the end portions 123a and 124a being in contact with the ceiling surface.

  The instrument body 110 is provided with, for example, at least two chains for suppressing the light source module 10 from dropping. For example, two chains are provided near both ends in the X-axis direction. On the second surface 21b of the support 11 of the light source module 10, for example, a plurality of hooks corresponding to each chain are provided. After the fixture body 110 is screwed to the ceiling, the end of each chain is hooked on the hook of the light source module 10 to suspend the light source module 10.

  After the light source module 10 is suspended, the light source module 10 and the power supply circuit 115 are electrically connected, for example, by connecting a connector (not shown).

  After wiring, with the light source module 10 tilted around the X axis, the second portion 22 side of the support 11 is placed in the recess 112a, and each first claw portion 41b of each holding member 13 is attached to each mounting spring 114. Are engaged with the respective end portions 114a. Thereafter, the light source module 10 is returned to the horizontal position so that the third portion 23 side of the support 11 is placed in the recess 112a, and each second claw portion 42b of each holding member 13 is inserted into each mounting spring 114. Engage with the end 114b.

  Thereby, the light source module 10 is supported by the fixture main body 110, and the lighting fixture 100 is attached to a ceiling. In addition, contrary to the above, after engaging each 2nd nail | claw part 42b with each edge part 114b, you may engage each 1st nail | claw part 41b with each edge part 114a.

  When removing the light source module 10 from the instrument main body 110, for example, after releasing the engagement state between each first claw portion 41b and each end portion 114a, each second claw portion 42b and each end portion 114b, The respective engagement states are 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. .

  When the appliance main body 110 is screwed to a ceiling board or the like, for example, the case 112 may be deformed by tightening the screws too much. If the housing 112 is deformed when the mounting spring 114 is engaged to support the light source module 10, for example, the positions of the mounting spring 114 and the claws 41b and 42b are shifted. Thereby, it becomes difficult to attach the light source module 10 to the instrument main body 110 or to remove it.

  In the lighting fixture 100 according to the present embodiment, the protrusion 126 is provided in the vicinity of the attachment spring 114 of the bottom plate portion 120. In the lighting fixture 100, when the fixture main body 110 is screwed to the ceiling surface, the protrusion 126 comes into contact with the ceiling surface. Thereby, in the lighting fixture 100, the deformation | transformation of the housing | casing 112 in the vicinity of the attachment spring 114 can be suppressed. For example, the light source module 10 can be easily attached to and detached from the instrument main body 110. For example, it is possible to easily attach the instrument main body 110 to an attachment target such as a ceiling.

  By providing a plurality of protrusions 126, deformation of the housing 112 can be suppressed more appropriately. By disposing the protrusions 126 on both sides of the attachment spring 114 in the X-axis direction, the deformation of the housing 112 can be further suppressed.

  For example, the distance D1 is set to 20 mm or less. Thereby, the deformation | transformation of the housing | casing 112 can be suppressed more appropriately. For example, the distance D1 is set to 10 mm or less. Thereby, the deformation of the housing 112 can be further suppressed.

  The height of the protrusion 126 is preferably equal to or less than the height of the end portions 123a and 124a. Thereby, it can suppress that a clearance gap produces between each edge part 123a, 124a and a ceiling surface. However, if the difference between the height of the protrusion 126 and the height of each of the end portions 123a and 124a is increased, the effect of suppressing the deformation of the housing 112 is weakened. For this reason, the difference between the height of the protrusion 126 and the height of each of the end portions 123a and 124a is preferably, for example, 5 mm or less. It is most preferable that the height of the protrusion 126 is substantially the same as the height of each of the end portions 123a and 124a.

(Third embodiment)
FIG. 8A and FIG. 8B are perspective views schematically showing a lighting fixture according to the third embodiment.
FIG. 9 is a cross-sectional view schematically illustrating a lighting fixture according to the third embodiment.
FIG. 10 is a partial perspective view schematically showing a part of the lighting fixture according to the third embodiment.
As illustrated in FIGS. 8 to 10, the lighting fixture 200 includes the light source module 10 described in the first embodiment and the fixture main body 210 that supports the light source module 10.

  The instrument main body 210 includes a housing 212 and an attachment spring 214, similarly to the instrument main body 110 described in the second embodiment. The housing 212 is also provided with a recess 212 a that houses at least a part of the light source module 10. The functions of the housing 212 and the mounting spring 214 are substantially the same as the functions of the housing 112 and the mounting spring 114 of the instrument main body 110 of the second embodiment. About the housing | casing 212 and the attachment spring 214, the detailed description is abbreviate | omitted about the part which can be the same as that of the housing | casing 112 and the attachment spring 114.

  The housing 212 includes, for example, a bottom plate portion 220, a first side plate portion 221, and a second side plate portion 222. The bottom plate part 220, the first side plate part 221 and the second side plate part 222 can be the same as those in the second embodiment. Similar to the bottom plate portion 120, the bottom plate portion 220 has a third surface 220a that faces the second surface 21b, and a fourth surface 220b opposite to the third surface 220a. A recess 212 a is formed by the bottom plate portion 220, the first side plate portion 221, and the second side plate portion 222.

  The bottom plate part 220 is provided with openings 220c and 220d. The opening 220c is disposed at a position facing the first grip 41 in the Z-axis direction. The opening 220d is disposed at a position facing the second grip portion 42 in the Z-axis direction. In this example, three openings 220c and three openings 220d are provided for each of the three holding members 13 of the light source module 10.

  The attachment spring 214 is attached to the bottom plate part 220. In this example, the attachment spring 214 is attached to the fourth surface 220b. The attachment spring 214 is bent in a substantially U shape, and has a portion along the bottom plate portion 220, a portion along the first side plate portion 221, and a portion along the second side plate portion 222.

  In this example, a portion along the first side plate portion 221 of the mounting spring 214 enters the recess 212a through the opening 220c. A portion along the second side plate portion 222 enters the recess 212a through the opening 220d.

  One end 214a of the mounting spring 214 is bent inward and engages with the first claw portion 41b of the light source module 10 accommodated in the recess 212a. The other end 214b of the mounting spring 214 is bent inward and engages with the second claw portion 42b of the light source module 10 accommodated in the recess 212a.

  In the second embodiment, the end portions 114a and 114b of the mounting spring 114 are caused to enter the recess 112a from the side plate portions 121 and 122, respectively. Without being limited to this, as shown in the present embodiment, the end portions 214 a and 214 b of the attachment spring 214 may be caused to enter the recess 212 a from the bottom plate portion 220. The housing 212 in this example does not include the inclined plate portions 123 and 124. For this reason, when the end portions 214a and 214b of the attachment spring 214 are caused to enter the recess 212a from the side plate portions 221 and 222, the attachment spring 214 is exposed to the outside. Therefore, in the housing 212, the end portions 214a and 214b of the attachment spring 214 are caused to enter the recess 212a from the bottom plate portion 220. Thereby, it can suppress that the designability of the lighting fixture 200 is impaired, for example. Further, the attachment spring 214 may be attached to the third surface 220a, for example. That is, the attachment spring 214 may be attached within the recess 212a.

  Each of the end portion 221a of the first side plate portion 221 and the end portion 222a of the second side plate portion 222 is bent in a substantially U shape toward the inside. Further, the end portion 221a and the end portion 222a are tapered so as to narrow the width of the concave portion 212a in the Y-axis direction. In this way, by making the end portion 221a and the end portion 222a into a tapered shape, for example, a space for elastically deforming the mounting spring 214 when releasing the engagement with the claw portions 41b and 42b is secured. Therefore, it is possible to make it difficult to visually recognize the attachment spring 214 and the like from the indoor side.

  The notch 221b in which the notch 221b is provided in the end 221a is disposed at a position facing the end 214a of the attachment spring 214. The end 222 a is provided with a notch 222 b, and the notch 222 b is disposed at a position facing the end 214 b of the attachment spring 214. Each notch 221b, 222b is provided corresponding to each attachment spring 114. In this example, three notches 221 b and 222 b are provided in the housing 212.

  In this example, the end portions 221a and 222a are bent in a substantially U shape, and the notches 221b and 222b are provided in the bent portions so that the end portions of the side plate portions 221 and 222 are not cut. ing. Thereby, for example, even when the notches 221b and 222b are provided, it is possible to suppress a decrease in strength of the housing 212.

  A rod-shaped jig is inserted into the notch 221b, the end 214a of the mounting spring 214 is pushed, and the mounting spring 214 is elastically deformed so that the end 214a is brought closer to the first side plate 221 side. Thereby, the engagement state of the 1st nail | claw part 41b and the edge part 214a is cancelled | released.

  A rod-shaped jig is inserted into the notch 222b, the end 214b of the mounting spring 214 is pushed, and the mounting spring 214 is elastically deformed so that the end 214b is brought closer to the second side plate 222 side. Thereby, the engagement state of the 2nd nail | claw part 42b and the edge part 214b is cancelled | released. By making the shape of the portion into which the jig is inserted into the cutouts 221b and 222b, for example, the operability when inserting the jig can be improved as compared with a through hole or the like. For example, the amount of movement of the jig in the inserted state can be increased compared to a through-hole or the like.

  Also in the housing 212, a protrusion 226 is provided on the fourth surface 220b. For example, a plurality of protrusions 226 are provided on the fourth surface 220b. In this example, for example, when the lighting apparatus 200 is installed on the ceiling, each of the protrusions 226 contacts the ceiling surface.

  Also in this example, each protrusion 226 is disposed in the vicinity of the attachment spring 214. A distance D1 in the X-axis direction between the protrusion 226 and the attachment spring 214 is, for example, 30 mm or less. For example, the protrusions 226 are disposed on both sides in the X-axis direction with the attachment spring 214 interposed therebetween. Thereby, for example, when the lighting apparatus 200 is installed on a ceiling or the like, deformation of the housing 212 in the vicinity of the attachment spring 214 can be suppressed.

  The procedure for installing the lighting fixture 200 on the ceiling and the procedure for removing the light source module 10 from the fixture main body 210 are substantially the same as the procedure described in the second embodiment.

FIG. 11 is a partial cross-sectional view schematically showing a part of the lighting fixture according to the third embodiment.
As shown in FIG. 11, the attachment spring 214 is attached to the fourth surface 220b, for example, near the center in the Y-axis direction. For example, the attachment spring 214 is attached near the center in the Y-axis direction of the fourth surface 220b by the screw 228. Moreover, in the lighting fixture 200, each protrusion 226 creates a gap between the fourth surface 220b and the mounting surface (for example, the ceiling surface).

  Thereby, in the lighting fixture 200, as shown in FIG. 11, when the jig is inserted into the notch 221b and the end 214a of the attachment spring 214 is pushed to elastically deform the attachment spring 214, the attachment spring A part of 214 can be separated from the fourth surface 220b. A part of the attachment spring 214 can be moved to the attachment surface side.

  Thereby, for example, the engagement between the first claw portion 41b and the end portion 214a 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 41b and the end portion 214a, by moving a part of the attachment spring 214 to the attachment surface side, for example, the end portion 214a necessary for releasing the engagement. The amount of movement toward the first side plate portion 221 can be reduced. Therefore, for example, the distance in the Y-axis direction between the end portion 214a and the first side plate portion 221 can be shortened as compared with the case where the attachment spring 114 cannot move to the attachment surface side. For example, the width of the housing 212 in the Y-axis direction can be reduced.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention.
