The power supply circuit 36 receives power supply from the power supply terminal block.

  The module cover 37 is a cover that covers the LED 35 and is a component called by a name such as a globe. The module cover 37 is formed in a substantially rectangular parallelepiped shape that is hollow and has an opening, for example, by a translucent resin material (for example, acrylic resin). The module cover 37 is fixed to the main body 31 with the opening side facing the main body front surface 31B. A substrate 351 on which the LEDs 35 are mounted is disposed in the opening of the module cover 37. The module cover 37 protects the LED 35 and diffuses light from the LED 35.

  The main body 31 is a housing that supports the module cover 37 and accommodates the power supply circuit 36. The main body 31 is formed in a substantially rectangular parallelepiped shape having a front surface and having an opening. The main body 31 has an opening on the main body back surface 31 </ b> A side, and a power circuit 36 is accommodated in the opening. A substrate 351 of the LED 35 is disposed on the side opposite to the opening of the main body 31. A groove into which the open end of the module cover 37 is fitted is formed on the side surface of the main body 31. The main body 31 is attached to the attachment component 2 by the plate-like body 40 and the protrusion 50.

  The plate-like body 40 and the protrusion 50 are connecting tools for attaching the LED module 3 to the attachment component 2. The plate-like body 40 and the protrusion 50 are respectively inserted into the first insertion hole 24 and the second insertion hole 25 in a state where the main body rear surface 31A of the LED module 3 is directed to the attachment component 2 side, and the LED module 3 is attached. It is attached to the part 2. Below, the 1st insertion hole 24 and the 2nd insertion hole 25 of the attachment component 2 are demonstrated.

  FIG. 3 is a perspective view showing an attachment part according to Embodiment 1. FIG. In the attachment component 2 shown in FIG. 3, a first insertion hole 24 is formed in the first holding portion 211, and a second insertion hole 25 is formed in the second holding portion 212. The first insertion hole 24 and the second insertion hole 25 form a pair so as to face each other, and in the entire attachment part 2, two pairs of the first insertion hole 24 and the second insertion hole 25 are formed.

  FIG. 4 is a perspective view showing a first insertion hole and a second insertion hole of the mounting part according to Embodiment 1. The first insertion hole 24 and the second insertion hole 25 are through holes that penetrate through the plate-like member that forms the attachment part 2. The first insertion hole 24 includes an upper opening 241 and a lower opening 242 that is continuous with the upper opening 241.

  Both the upper opening 241 and the lower opening 242 are formed in a substantially rectangular shape. The upper opening 241 and the lower opening 242 are continuous to form a T-shaped opening as a whole. More specifically, the short sides of the upper opening 241 and the lower opening 242 are oriented in the Z direction in the state shown in FIG. 2 in which the mounting part 2 is installed on the ceiling 9, and the upper opening 241 and the lower opening 242 are in the Z direction. It is continuous. The long side of the upper opening 241 is in contact with the long side of the lower opening 242. The long side of the lower opening 242 is shorter than the long side of the upper opening 241 and is arranged at the center of the long side of the upper opening 241. As a result, the upper opening 241 can be inserted and withdrawn at the front end 41 of the plate-like body 40 described later, and the lower opening 242 is prevented from being inserted and withdrawn from the front end 41.

  The second insertion hole 25 is formed in a shape having a substantially square opening. Each side of the opening faces the Z direction and the X direction in the state shown in FIG. The size is such that the protrusion 50 can be inserted. Hereinafter, the plate-like body 40 and the protrusion 50 of the LED module 3 will be described.

  FIG. 5 is a perspective view showing the LED module according to Embodiment 1. FIG. As shown in FIG. 5, the LED module 3 includes a plate-like body 40 extending from the main body 31 toward the side, and a protrusion 50 protruding from the main body 31 to the side opposite to the plate-like body 40. The plate-like body 40 and the protrusion 50 are disposed on the main body rear surface 31 </ b> A side and on the long side surface of the main body 31. The plate-like body 40 and the projection 50 are aligned in a substantially straight line to form a pair. In the entire LED module 3, two pairs of plate-like bodies 40 and protrusions 50 are arranged.

  6 is a perspective view showing a plate-like body and protrusions of the LED module according to Embodiment 1. FIG. The plate-like body 40 and the protrusion 50 shown in FIG. 6 are integrally formed by bending a single plate-like member (for example, a metal plate such as stainless steel or spring steel). A plate-like body 40, a connecting portion 45, and a protrusion 50 are formed in order from the end. The plate-like body 40 is formed in a shape having an intermediate part 43 and a tip part 41.

  The intermediate portion 43 is a portion in which the width of the plate-like body 40 is formed to be constant. Extended. The width is smaller than the width of the connecting portion 45. In addition, the width of the intermediate portion 43 is smaller than the long side of the lower opening 242 of the first insertion hole 24, and the thickness of the intermediate portion 43 is smaller than the short side of the lower opening 242. Accordingly, the intermediate portion 43 can be inserted into the upper opening 241 and can be engaged with the lower opening 242. The intermediate portion 43 extends linearly from the main body 31, and then bends approximately 90 degrees toward the main body front surface 31B at the first bent portion.

  The tip portion 41 is a T-shaped structure that is continuous with the intermediate portion 43. The width of the tip portion 41 is larger than the width of the intermediate portion 43. Further, the width of the distal end portion 41 is smaller than the long side of the upper opening 241 of the first insertion hole 24 and larger than the long side of the lower opening 242. The thickness of the tip portion 41 is smaller than the short side of the upper opening 241. As a result, the distal end portion 41 can be inserted into the upper opening 241 and can be locked to the lower opening 242. Since the front end portion 41 can be locked to the lower opening 242, it is possible to prevent the LED module 3 from falling off the attachment component 2.

  The connecting portion 45 is a portion that connects the plate-like body 40 and the protrusion 50, and is disposed on the main body back surface 31 </ b> A. Fixing portions 46 that are bent from the connection portion 45 along the side surface of the main body 31 are formed on both sides of the connection portion 45. When the fixing portion 46 is fixed to the side surface of the main body 31 by the fastener 47, the connecting portion 45 is fixed to the main body rear surface 31A.

  The protrusion 50 is a structure formed by bending a plate-like member into a semicircular cross section. The protrusion 50 protrudes toward the side of the main body side surface 31C, and can be elastically deformed when pressed from a direction opposite to the protruding direction. The protrusion 50 includes a semicircular portion 51 and a connecting portion 52 that connects the semicircular portion 51 and the connecting portion 45.

  The semicircular portion 51 is a portion that bends in a semicircular cross section, and that the bend protrudes to the side of the main body 31 to form a protrusion 50. The diameter of the semicircular portion 51 (W shown in FIG. 6) is slightly larger than the height of the second insertion hole 25 in the Z direction, and its width (D shown in FIG. 6) is in the X direction of the second insertion hole 25. It is almost the same as the width. The semicircular portion 51 can be fitted and inserted into the second insertion hole 25 by elastic deformation. When the semicircular portion 51 is inserted into the second insertion hole 25, the semicircular portion 51 pushes the opening side surface of the second insertion hole 25 by a restoring force that attempts to restore the original shape. Thereby, the semicircular portion 51 can be locked in the direction of the surface of the second holding portion 212.

  The connecting portion 52 is a portion that extends in a direction along the side surface of the main body 31 from the connecting portion 45 and then bends in a U-shaped cross section. When the projection 50 is pressed, the connecting portion 52 can be elastically deformed so that the opening degree between the side surface 31C of the main body and the semicircular portion 51 of the projection 50 becomes small. Thereby, when the main body 31 is attached to the LED module attachment portion 21, the protrusion 50 is pressed against the second holding portion 212, the connecting portion 52 is elastically deformed, and the protrusion 50 is connected to the main body side surface 31C and the second holding portion 212. It becomes possible to put between.

  The distance (L2) from the tip of the semicircular portion 51 farthest from the main body side surface 31C to the main body side surface 31D facing the main body side surface 31C is between the first holding portion 211 and the second holding portion 212. (See FIGS. 4 and 6). Thereby, in a state where the LED module 3 is attached to the attachment part 2, the protrusion 50 does not come off from the second insertion hole 25 even if the attachment part 2 is displaced in the direction of the first holding portion 211. That is, it is possible to prevent the LED module 3 from dropping from the attachment component 2 by this relationship.

  Below, the method to assemble the lighting fixture 1 using the attachment component 2 and the LED module 3 is demonstrated.

  7 and 8 are cross-sectional views showing a method for assembling the lighting fixture according to Embodiment 1. FIG. As shown in FIG. 7A, first, the tip end portion 41 of the plate-like body 40 is inserted into the first insertion hole 24 of the LED module attachment portion 21. The distal end portion 41 is inserted into the upper opening 241 of the first insertion hole 24. The distal end portion 41 and the first bent portion 42 are inserted into the first insertion hole 24, and the first bent portion 42 is fitted into the lower opening 242 of the first insertion hole 24. In this state, the insertion and removal of the tip end portion 41 is blocked by the lower opening 242, and the LED module 3 is in a state of hanging from the attachment component 2. In this state, the LED module 3 is prevented from falling. The operator does not need to support the LED module 3 by hand. The worker connects the connector connected to the power supply terminal block and the connector connected to the power supply circuit 36.

  Next, as shown in FIG. 7B, the distal end portion 41 of the plate-like body 40 is further inserted into the first insertion hole 24. The LED module 3 is lifted to the LED module mounting portion 21 side, and the protrusion 50 is pressed against the second holding portion 212. The protrusion 50 is pressed from the second holding part 212 and is elastically deformed. As shown in FIG. 8C, a part of the protrusion 50 abuts on the second holding part 212.

  When the LED module 3 is further lifted, the protrusion 50 reaches the end of the second insertion hole 25 as shown in FIG. The protrusion 50 is released from the elastically deformed state at the second insertion hole 25 and is locked to the second insertion hole 25 as shown in FIG. Thus, the assembly of the lighting fixture 1 is completed.

  As described above, in the lighting fixture 1 according to the present embodiment, the first insertion hole 24 and the second insertion hole 25 are formed in the attachment component 2, and the plate-like body 40 and the protrusion 50 are formed in the LED module 3, respectively. ing. The distance from the tip 41 of the plate-like body 40 to the tip of the protrusion 50 is greater than the distance between the first holding part 211 and the second holding part 212. Further, when pressing is applied to the protrusion 50, the protrusion 50 is elastically deformed. According to the lighting apparatus 1, the LED module 3 can be attached to the LED module attachment portion 21 by elastically deforming the protrusion 50.

  In the first insertion hole 24, an upper opening 241 and a lower opening 242 are formed continuously, and the width of the long side of the lower opening 242 is larger than the width of the intermediate part 43 and smaller than the width of the tip part 41. Thereby, the front-end | tip part 41 can be latched to the lower opening 242. FIG. Further, the distance from the tip of the semicircular portion 51 that is farthest from the main body side surface 31C to the main body side surface 31D that faces the main body side surface 31C is between the first holding portion 211 and the second holding portion 212. Greater than distance. Thereby, even if the LED module 3 is shifted to the first holding portion 211 side, the protrusion 50 is not detached from the second insertion hole 25. According to the luminaire 1, the LED module 3 is prevented from falling from the attachment part 2.

  A first holding portion 211 having a first insertion hole 24 and a second holding portion 212 having a second insertion hole 25 are formed in the attachment component 2. On the other hand, the LED module 3 is provided with a plate-like body 40 and a protrusion 50. According to this embodiment, the attachment structure of the LED module 3 to the attachment component 2 is easy, and the luminaire 1 with a small number of components can be provided. For example, since the plate-like body 40 and the protrusion 50 are formed by bending one plate-like member, the lighting fixture 1 has a small number of parts.

Its width and thickness are substantially the same as those of the intermediate portion 43. Its size is larger than that of the first insertion hole 24, and its height is larger than the sum of the short sides of the upper opening 241 and the lower opening 242. As a result, when the intermediate portion 43 is inserted into the first insertion hole 24, the positioning portion 48 is caught by the inlet of the first insertion hole 24 and comes into contact with the surface of the first holding portion 211.

  The distance (L3) from the surface of the positioning part 48 in contact with the first holding part 211 to the root of the semicircular part 51 of the protrusion 50 is the distance (L1) between the first holding part 211 and the second holding part 212. Is approximately equal to or slightly larger (see FIGS. 4 and 9). As a result, the surface of the positioning portion 48 comes into contact with the first holding portion 211 in a state where the protrusion 50 is locked in the second insertion hole 25. Below, the assembly method of the lighting fixture 1 is demonstrated.

The protrusion 50 is released from the elastically deformed state at the second insertion hole 25 and is locked to the second insertion hole 25 as shown in FIG. The positioning unit 48 comes into contact with the surface of the first holding unit 211.

  As described above, the lighting fixture 1 according to Embodiment 2 includes the positioning unit 48 that determines the position of the side surface of the LED module 3 in a state where the LED module 3 is attached to the attachment component 2. The positioning portion 48 is in contact with the surface of the first holding portion 211 in a state where the plate-like body 40 is inserted into the first insertion hole 24 and the protrusion 50 is inserted into the second insertion hole 25, so that the LED module 3 is 1 It does not bias toward the holding part 211 side. Thereby, it is possible to maintain the state in which the protrusion 50 is inserted into the second insertion hole 25. According to the second embodiment, the LED module 3 is less likely to drop from the attachment component 2. Since the lighting device 1 can maintain the state in which the protrusion 50 is inserted into the second insertion hole 25 by the positioning portion 48, the lighting device 1 can be installed on, for example, an inclined ceiling 9 or a wall surface.

The first holding member 211A and the second holding member 212A are formed by bending an inverted T-shaped plate member. The first holding member 211A is formed in a shape having a support portion 213 and a central portion 215, and the second holding member 212A is formed in a shape having a support portion 214 and a central portion 216, respectively.

  The support portions 213 and 214 are portions extending on both sides of the inverted T-shaped first holding member 211A and the second holding member 212A. The support portions 213 and 214 extend from the central portion of the inverted T shape toward the side surface of the main body portion 22, then bend and extend in a direction along the surface of the side surface of the main body portion 22. The support portions 213 and 214 are fixed to the side surface of the main body portion 22.

  The central portions 215 and 216 are the center of the inverted T-shaped first holding member 211A and the second holding member 212A, and the attachment component 2 is installed on the ceiling 9 from the end of the frame portion 222 of the main body portion 22 − This is a portion extending in the Z direction. The central portions 215 and 216 are formed in a shape having a vertical surface extending in parallel with the XZ plane from the end portion of the frame portion 222 and an inclined surface that is bent from the vertical surface to the inside of the main body portion 22. The inclined surfaces of the central portions 215 and 216 extend to the surface on the back side of the main body portion 22 and support the surfaces. A first insertion hole 24 is formed in the inclined surface of the central portion 215, and a third insertion hole 26 is formed in the vertical surface of the central portion 215. A second insertion hole 25 is formed in the central portion 216 from the inclined surface to the vertical surface. The first insertion hole 24 and the second insertion hole 25 are through holes having the same shape as in the first and second embodiments.

  The third insertion hole 26 is formed in a shape having a substantially rectangular opening, and penetrates the plate-like member forming the first holding member 211A. The third insertion hole 26 is formed discontinuously with the lower opening 242 in the + Z direction with respect to the lower opening 242 of the first insertion hole 24 in a state where the attachment component 2 is installed on the ceiling 9. The side of the opening of the third insertion hole 26 faces the X direction and the Z direction in a state where the attachment component 2 is installed on the ceiling 9. The size of the opening is such that the side in the X direction is substantially the same as the length of the side in the X direction of the upper opening 241 of the first insertion hole 24 and is larger than the width of the intermediate portion 43. The side in the Z direction is smaller than the side in the X direction. Since the side in the X direction of the third insertion hole 26 is larger than the width of the intermediate portion 43, the tip of the second bent portion 44 of the plate-like body 40 can be inserted.

  FIG. 14 is a perspective view showing a plate-like body and protrusions of the LED module according to Embodiment 3. The plate-like body 40 has an intermediate portion 43 that is bent at the second bent portion 44.

  The intermediate portion 43 extends to the side of the main body side surface 31D by a length W3, and is bent by approximately 90 ° toward the main body rear surface 31A at the second bent portion 44. The intermediate portion 43 is further bent by the second bent portion 44 and then extends the length H3 to reach the first bent portion. The distance W4 in the horizontal direction (Y direction) from the second bent portion 44 to the distal end portion 41 is the distance from the side in the X direction of the lower opening 242 of the central portion 215 of the first holding member 211A to the side surface of the main body portion 22 ( It is smaller than L4) shown in FIG. Thereby, in the intermediate part 43, the part from the 2nd bending part 44 to the front-end | tip part 41 can be accommodated between the 1st holding member 211A and the side surface of the main-body part 22 in the state engaged with the lower opening 242. .

  In the intermediate portion 43, the length H3 from the second bent portion 44 to the first bent portion 42 is from the side in the X direction of the lower opening 242 of the first insertion hole 24 shown in FIG. 13 to the X direction of the third insertion hole 26. Is larger than the distance (H1 shown in FIG. 13) to the side on the −Z side. Further, the length H3 is a distance from the side in the X direction of the lower opening 242 of the first insertion hole 24 shown in FIG. 13 to the side on the + Z side of the side in the X direction of the third insertion hole 26 (FIG. 13). Smaller than H2). The length H3 is equal to the distance from the side in the X direction of the lower opening 242 to the vicinity of the center of the third insertion hole 26. In the intermediate portion 43, the second bent portion 44 can be inserted into the third insertion hole 26 when the distal end portion 41 is locked to the lower opening 242 in the assembly of the lighting fixture 1. Below, the method to assemble the lighting fixture 1 using the attachment component 2 and the LED module 3 is demonstrated.

  15 and 16 are perspective views showing a method for assembling a lighting fixture according to the third embodiment. As shown in FIG. 15A, first, the tip portion 41 of the plate-like body 40 of the LED module 3 is positioned in front of the first insertion hole 24 of the first holding member 211 </ b> A of the attachment component 2. Then, the distal end portion 41 is inserted into the upper opening 241 of the first insertion hole 24.

  Next, the distal end portion 41 of the plate-like body 40 is inserted into the first insertion hole 24, and the first bent portion 42 of the intermediate portion 43 of the plate-like body 40 is fitted into the lower opening 242 of the first insertion hole 24. . As shown in FIG. 15B, the intermediate portion 43 engages with the lower opening 242. The tip portion 41 is locked to the lower opening 242. In this state, the lower opening 242 prevents the tip 41 from being inserted and removed, and the LED module 3 can be hung from the mounting component 2. When the LED module 3 is hung from the attachment component 2, the second bent portion 44 of the intermediate portion 43 is positioned in the third insertion hole 26 of the first holding member 211 </ b> A. The plate-like surface of the intermediate portion 43 is in contact with the side of the third insertion hole 26. The LED module 3 hangs on the attachment component 2 in a state where there is a gap in the side surface 22A on the second holding member 212A side of the attachment component 2.

  Next, the main body side surface 31 </ b> C on the protrusion 50 side of the LED module 3 is pushed up, and the protrusion 50 is pressed against the second holding member 212 </ b> A of the attachment component 2. The protrusion 50 is elastically deformed by being pressed by the second holding member 212A. When the LED module 3 is pushed up from the main body front face 31 </ b> B side, the tip end portion 41 and the intermediate portion 43 of the plate-like body 40 are further inserted into the first insertion hole 24 and the second bent portion 44 is inserted into the first insertion hole 24. Come to be located. When the protrusion 50 reaches the second insertion hole 25 of the second holding member 212 </ b> A, the protrusion 50 is released from the state of being elastically deformed by the second insertion hole 25 and is locked to the second insertion hole 25. Thereby, as shown in FIG. 16C, the LED module 3 is attached to the attachment part 2, and the assembly of the lighting fixture 1 is completed.

  As described above, in the lighting fixture 1 according to the present embodiment, the intermediate portion 43 of the plate-like body 40 of the LED module 3 is formed in a shape having the second bent portion 44 that bends from the main body side surface 31D to the main body back surface 31A. Has been. A first insertion hole 24 is formed in the first holding member 211 </ b> A of the attachment part 2, and the distal end portion 41 and the second bent portion of the plate-like body 40 are between the first holding member 211 </ b> A and the side surface of the main body 22. 44 can be accommodated. The intermediate portion 43 is bent at the second bent portion 44 from the main body side surface 31D to the main body rear surface 31A. For this reason, in the state in which the 2nd bending part 44 was accommodated between the 1st holding member 211A and the main-body-part 22 side surface, a big space is not required for main-body side surface 31D. In the lighting fixture 1 according to the third embodiment, the space in the side surface direction of the main body 31 of the LED module 3 can be reduced as compared with the first and second embodiments. For example, even in the lighting fixture 1 in which the reflecting plate 28 is not provided on the side surface of the mounting component 2, the LED module 3 can be prevented from falling from the mounting component 2 as in the first and second embodiments.

  The first holding member 211 </ b> A and the second holding member 212 </ b> A have center portions 215 and 216 and support portions 213 and 214. The inclined surfaces of the central portions 215 and 216 support the back side surface of the main body portion 22, and the support portions 213 and 214 are fixed to the side surface of the main body portion 22. The first holding member 211 </ b> A and the second holding member 212 </ b> A can reinforce the corner portion formed by the side surface and the back surface of the main body portion 22 to increase the mechanical strength of the lighting fixture 1.

  In the first holding member 211 </ b> A and the second holding member 212 </ b> A, the first insertion hole 24 and the second insertion hole 25 are formed on the inclined surfaces of the central portions 215 and 216, respectively. For this reason, when accommodating the LED module 3 from the opening part 221 of the main-body part 22 to the inner side, it is easy to visually recognize the 1st insertion hole 24 and the 2nd insertion hole 25. FIG. Therefore, the luminaire 1 according to the third embodiment can easily assemble the attachment component 2 and the LED module 3.

  The first holding member 211 </ b> A is formed with a third insertion hole 26 disposed below the first insertion hole 24. In the third insertion hole 26, the second bent portion 44 of the intermediate portion 43 can be inserted in a state where the tip portion 41 of the plate-like body 40 of the LED module 3 is locked to the lower opening 242 of the first insertion hole 24. Is possible. In assembling the lighting fixture 1, the second bent portion 44 of the plate-like body 40 comes into contact with the plate-like surface of the first holding member 211 </ b> A when the tip portion 41 of the plate-like body 40 is locked to the lower opening 242. There is nothing. For this reason, even when the plate-like body 40 is formed in a shape having the second bent portion 44, it is possible to provide a gap on the side surface 22A on the second holding member 212A side of the mounting component 2 in the assembly of the lighting fixture 1. It is. When the LED module 3 is attached to the opening 221 of the main body 22, it is easy to confirm the positional relationship between the second insertion hole 25 and the protrusion 50. The lighting fixture 1 according to Embodiment 3 is easy to assemble.

  As mentioned above, although embodiment of this invention was described, the lighting fixture 1 which concerns on embodiment of this invention can be variously deformed.

  For example, in the above-described embodiment, a configuration in which the width of the tip portion 41 of the plate-like body 40 is larger than the width of the intermediate portion 43 and the long side of the upper opening 241 is larger than the long side of the lower opening 242 is described. did. However, the plate-like body 40 and the first insertion hole 24 of the present invention are not limited to this form. The 1st insertion hole 24 should just be comprised from the upper opening 241 which can insert the front-end | tip of the plate-shaped body 40, and the lower opening 242 which blocks the front-end | tip of the plate-shaped body 40 continuously with the upper opening 241. . The plate-like body 40 only needs to have an intermediate portion 43 that can be engaged with the lower opening 242 and a tip portion 41 that is locked to the lower opening 242.

  FIG. 17 is a perspective view showing a modification of the first insertion hole and the plate-like body. As shown in FIG. 17A, the plate-like body 40 may be constituted by an intermediate portion 43 having an opening and a tip portion 41 having the same width as the intermediate portion 43 and having no opening. When such a plate-like body 40 is employed, the first insertion hole 24 is continuous with the upper opening 241 and the same width as the upper opening 241 as shown in FIG. And a lower opening 242 having a convex portion. When the width of the opening of the intermediate portion 43 of the plate-like body 40 is W2, the width of the tip 41 is W1, the width of the upper opening 241 of the first insertion hole 24 is D1, and the width of the convex portion of the lower opening 242 is D2. , D1> W1> W2> D2 may be satisfied.

  As shown in FIG. 17C, the tip portion 41 and the intermediate portion 43 of the plate-like body 40 may form an L-shaped structure for the plate-like body 40. In the case of such a plate-like body 40, the upper opening 241 and the lower opening 242 of the first insertion hole 24 may form an inverted L shape. When the width of the intermediate portion 43 of the plate-like body 40 is W2, the width of the tip portion 41 is W1, the width of the upper opening 241 of the first insertion hole 24 is D1, and the width of the lower opening 242 is D2, D1> W1> What is necessary is just to satisfy | fill the relationship of D2> W2. This relationship is the same as in the first embodiment.

  In the said embodiment, although the processus | protrusion 50 demonstrated the form formed through the plate-shaped body 40 and the connection part 45, the connection part 45 is not an essential structure. For example, the protrusion 50 may be directly connected to the intermediate portion 43 of the plate-like body 40, or these configurations may be integrally formed. The protrusion 50 may be formed by bending the intermediate portion 43.

  In the embodiment described above, the positioning portion 48 is branched in a substantially vertical direction with respect to the intermediate portion 43 and is larger than the first insertion hole 24. However, the branching shape is not limited to the above-described embodiment. . The positioning portion 48 only needs to have a shape that catches the inlet of the first insertion hole 24 when the intermediate portion 43 is inserted into the first insertion hole 24. For example, the width of the positioning portion 48 may be smaller than the long side of the lower opening 242 and the height of the positioning portion 48 may be larger than the sum of the short sides of the upper opening 241 and the lower opening 242.

  The positioning part 48 is not limited to a member branched from the plate-like body 40. The positioning portion 48 determines the position of the side surface of the main body 31 with respect to the first holding portion 211 in a state where the LED module 3 is attached to the attachment component 2, and maintains the state where the protrusion 50 is inserted into the second insertion hole 25. Any part can be used. In other words, the positioning portion 48 may be a portion that regulates the position of the LED module 3 so that the surface of the second holding portion 212 and the base of the semicircular portion 51 of the protrusion 50 are arranged on substantially the same surface. . For example, the positioning part 48 may be a member formed on the same side as the side on which the plate-like body 40 extends, or may be a member different from the plate-like body 40. The positioning part 48 may be a rectangular parallelepiped spacer.

  Moreover, the attachment part 2 may be provided with the part which the front-end | tip part 41 serves as the positioning part 48 and the front-end | tip part 41 contact | abuts.

  FIG. 18 is a cross-sectional view showing a modified example of the positioning portion. As shown in FIG. 18, the attachment component 2 includes a contact member 281. The abutting member 281 is formed on the back side (the surface in the −Z direction) of the reflecting plate 28 in the attachment component 2, the plate-like body 40 is inserted into the first insertion hole 24, and the protrusion 50 is the second insertion hole 25. The tip portion 41 is disposed at a position where the tip portion 41 comes into contact. As described above, the attachment part 2 may include a portion where the tip portion 41 also serves as the positioning portion 48 and the tip portion 41 abuts.

  In the above embodiment, the position and size of the protrusion 50 and the positioning portion 48 have been described as means for preventing the LED module 3 from falling off the attachment component 2. However, the protrusion 50 engages with the second insertion hole 25. Means may be provided.

  FIG. 19 is a cross-sectional view showing a modification of the protrusion. As shown in FIG. 19, the protrusion 50 may be bent to form the locking portion 53. The locking portion 53 is a portion that can be locked to the side surface of the second insertion hole 25 formed between the semicircular portion 51 and the connection portion 52 of the protrusion 50. For example, the locking portion 53 is formed by bending a plate-like member that forms the protrusion 50 into an inverted V shape inward of the semicircular portion 51.

  In the lighting fixture 1 shown in FIG. 19, when the semicircular portion 51 of the protrusion 50 is inserted into the second insertion hole 25, the locking portion 53 is locked to the side surface of the second insertion hole 25. Even if the protrusion 50 is pulled in the direction of being extracted from the second insertion hole 25, the protrusion 50 does not move away from the second insertion hole 25 because the locking portion 53 is locked to the second insertion hole 25. Absent. As described above, if the protrusion 50 has the locking portion 53, it is possible to prevent the LED module 3 from falling off the attachment component 2.

  In the above embodiment, the side in the X direction of the third insertion hole 26 is substantially the same as the length of the side in the X direction of the upper opening 241 of the first insertion hole 24. The length of the side is not limited to this. The length of the side in the X direction of the third insertion hole 26 may be larger than the width of the intermediate portion 43. That is, it is only necessary that the second bent portion 44 of the intermediate portion 43 can be inserted into the third insertion hole 26. For example, the side in the X direction of the third insertion hole 26 may be substantially the same as the length of the side in the X direction of the lower opening 242 of the first insertion hole 24.

  In the above embodiment, the first holding member 211A is formed in a shape having the third insertion hole 26, but the third insertion hole 26 has an arbitrary configuration.

  FIG. 20 is a perspective view showing a modification of the first holding member. As illustrated in FIG. 20, the first holding member 211 </ b> A may include the first insertion hole 24 and the third insertion hole 26 may not be formed. The first holding member 211 </ b> A can accommodate the second bent portion 44 of the plate-like body 40 in a state where the tip portion 41 of the plate-like body 40 is engaged with the lower opening 242 below the lower opening 242. It is sufficient that a space is provided. In the first holding member 211A shown in FIG. 20, the distance H4 from the lower side of the lower opening 242 of the first insertion hole 24 to the lower end portion of the first holding member 211A is from the second bent portion 44 to the first bent portion 42. When the front end portion 41 of the plate-like body 40 is smaller than the length (H3 shown in FIG. 14) and is locked to the lower opening 242, the first holding member 211A has a structure that contacts the second bent portion 44. not exist. For this reason, in the assembly of the lighting fixture 1, it is possible to provide a gap between the main body side surface 31 </ b> C and the side surface 22 </ b> A on the second holding member 212 </ b> A side of the attachment part 2. Since the position can be confirmed from the gap, the assembly work of the lighting fixture 1 is easy.

  The first holding member 211 </ b> A is a space below the lower opening 242 in which the second bent portion 44 of the plate-like body 40 can be accommodated in a state where the tip 41 of the plate-like body 40 is engaged with the lower opening 242. Therefore, for example, the first holding member 211 </ b> A may be formed in a shape having a recess having the same opening as that of the third insertion hole 26.
