However, the upper and lower portions in the following procedure are the same as the upper and lower portions in FIGS. 5A to 5D and FIGS. 6A to 6C.

  The operator places the support member 4 on the work table with the front surface of the bottom plate 40 facing upward. Then, the operator places the LED module 3 on the bottom plate 40 and pushes the substrate 31 downward so that the first hook portion 42 and the second hook portion 43 are inserted through the first groove portion 310, respectively (FIG. 5A and FIG. (See FIG. 6A). At this time, since the second groove portion 311 of the substrate 31 is provided at a position where the protrusion 44 cannot be inserted, the lower surface of the substrate 31 hits the tip (upper end) of the protrusion 44 and the substrate 31 moves in the thickness direction (up and down). Direction) (see FIG. 5B). The operator slides the LED module 3 to the right along the first direction while bending the substrate 31 (see FIGS. 5C, 5D, and 6C). When the LED module 3 moves to a position where the protrusion 44 can be inserted into the second groove 311, the substrate 31 returns to the original state and the protrusion 44 is inserted into the second groove 311. Here, the 1st nail | claw part 422 and the 2nd nail | claw part 432 are formed so that distance H1 with the front surface of the baseplate 40 along a 2nd direction may not become smaller than the thickness T1 of the board | substrate 31.

Therefore, the board | substrate 31 which moves to a 1st direction is pinched | interposed between the 1st nail | claw part 422 and the 2nd nail | claw part 432, and the front surface of the baseplate 40 (refer FIG. 5D and FIG. 6C).

  As described above, in the state where the protrusion 44 is inserted into the second groove portion 311, the first hook portion 42 and the second hook portion can be moved regardless of the direction of the first direction (leftward or rightward). The portion 43 cannot be pulled out from the first groove portion 310 (see FIG. 5D). As a result, the first hook portion 42, the second hook portion 43, and the protrusion 44 of the support member 4 are hooked on the first groove portion 310 and the second groove portion 311 of the substrate 31 of the LED module 3, thereby supporting the LED module 3. Supported by the member 4. That is, the operator can attach the LED module 3 to the support member 4 simply by pressing the LED module 3 placed on the front surface of the bottom plate 40 toward the bottom plate 40 and sliding it along the first direction. it can. For this reason, the work of caulking the metal member as in the conventional example is not required, so that the workability when assembling the light source unit 2 can be improved. Note that the operator slides the LED module 3 in a state where the substrate 31 is bent and the protrusion 44 is escaped from the second groove 311, and the first hook 42 and the second hook 43 are moved to the first groove 310. The LED module 3 can be removed from the support member 4 by pulling out from the support member 4.

  Subsequently, the operator inserts and accommodates the support member 4 to which the LED module 3, the power supply device 6, and the three fixtures 7 are attached into the case body 50 from one end side in the longitudinal direction. Further, the operator fixes the case main body 50 to the three fixtures 7 attached to the support member 4. That is, the operator inserts the fixing screws 53 into the screw insertion holes respectively provided at both ends and the center in the longitudinal direction of the rear wall 500 of the case main body 50, and is fixed to one screw hole 700 of each fixing piece 70. Screw in the screw 53.

  Subsequently, the operator inserts the attachment screw 83 into the screw insertion hole 810 of the second fixing portion 81 of the fixture 8, and then covers the end member 51 to which the waterproof packing 52 is attached over the end portion of the case body 50. Then, the operator inserts a screw into the screw insertion hole of the first fixing portion 80 of the fixture 8 in a state where the fixture 8 is put on the end member 51, and this screw is inserted into the rear wall of the case body 50. The other screw hole 700 of the fixing piece 70 is screwed through the hole provided in 500. That is, when the fixture 8 is fixed (screwed) to the fixture 7, the end member 51 and the waterproof packing 52 are prevented from coming off by the connecting portion 82 of the fixture 8 (see FIG. 7). The light source unit 2 is assembled as described above.

  Next, the construction procedure of the lighting fixture will be described. After attaching the instrument main body 1 to the ceiling, the operator opens the upper part of the light source unit 2 (the part above the second fixing part 81 of the two fixtures 8) on the first surface (lower surface) of the instrument main body 1. Insert inside. Then, the operator inserts the driver shaft into the recess 5140 of the cover portion 514 of the end member 51, and is inserted into the screw insertion hole 810 of the second fixing portion 81 through the hole provided in the bottom wall of the recess 5140. The mounting screw 83 is tightened. As a result, the attachment screw 83 is screwed into the screw hole 133 of the attachment piece 132 of the instrument body 1, so that the second fixing portion 81 of the attachment tool 8 is screwed (fixed) to the attachment piece 132 of the instrument body 1. Finally, it is preferable for the operator to cover the mouth of the concave portion 5140 exposed on the surface of the cover portion 514 with a tape or the like so as to be blindfolded. Thus, the installation of the lighting fixture is completed by attaching the light source unit 2 to the fixture main body 1 (see FIGS. 8A, 8B, and 8C).

  The light source unit 2 according to the present embodiment is configured as described above, and the LED module 3 placed on the front surface of the bottom plate 40 is pressed toward the bottom plate 40 and is slid along the first direction. As a result, the first hook portion 42, the second hook portion 43, and the protrusion 44 of the support member 4 are hooked on the first groove portion 310 and the second groove portion 311 of the substrate 31 of the LED module 3, thereby supporting the LED module 3. Supported by the member 4. Accordingly, the light source unit 2 and the lighting fixture according to the present embodiment do not require the work of caulking the metal member as in the conventional example, and therefore it is possible to improve the workability when assembling the light source unit 2. .

  In the light source unit 2 according to the present embodiment, the first arm portion 421 and the second arm portion 431 preferably have inclined surfaces 4210 and 4310 at the tips. The inclined surfaces 4210 and 4310 increase the distance from the first body 420 and the second body 430 along the first direction as they move away from the first claw 422 and the second claw 432 along the second direction. It is preferable that it be formed to be large.

  If the light source unit 2 according to the present embodiment is configured as described above, the edges of the first groove 310 and the second groove 311 hit the inclined surfaces 4210 and 4310 when the substrate 31 moves along the first direction. It is guided in a direction approaching the bottom plate 40. Therefore, the workability of the attaching operation of the LED module 3 to the support member 4 can be further improved.

  Furthermore, in the light source unit 2 according to the present embodiment, the protrusion 44 is preferably configured as follows. That is, the protrusion 44 has a height H3 from the front surface of the bottom plate 40 along the second direction, a height H2 from the front surface of the bottom plate 40 along the second direction to the tips of the inclined surfaces 4210 and 4310, and the substrate. It is preferable to be configured to be smaller than the difference between the thickness 31 of T31.

  If the light source unit 2 according to the present embodiment is configured as described above, when the substrate 31 moves along the first direction, the edges of the first groove portion 310 and the second groove portion 311 are reliably attached to the inclined surfaces 4210 and 4310. Can be applied.

  In the light source unit 2 according to the present embodiment, the protrusion 44 is preferably configured as follows. That is, the protrusion 44 has a distance in the second direction between the surface 440 facing the first claw portion 422 and the second claw portion 432 and the first claw portion 422 and the second claw portion 432 along the first direction. It is preferable that it is comprised so that it may shrink as it leaves | separates from the front surface of the baseplate 40 along.

  If the light source unit 2 according to the present embodiment is configured as described above, even if the LED module 3 is moved along the first direction while being attached to the support member 4, the surface 440 of the protrusion 44 is the above-described. Therefore, it becomes difficult for the substrate 31 to transfer the protrusion 44. As a result, it is possible to make it difficult to remove the LED module 3 (substrate 31) from the support member 4.

  In the light source unit 2 according to the present embodiment, the protrusion 44 includes a surface 441, a first body 420 and a second body 430 that face the first body 420 and the second body 430 along the first direction. Is preferably configured to extend along the second direction as the distance from the front surface of the bottom plate 40 increases.

  If the light source unit 2 according to the present embodiment is configured as described above, the contact area between the substrate 31 and the protrusion 44 is reduced, and the resistance force when the LED module 3 is slid in the first direction is reduced. Further improvement in sex can be achieved. In addition, if the upper end of the surface 441 of the protrusion 44 is formed in a curved surface shape, it is possible to prevent the protrusion 44 from being damaged when the substrate 31 moves.

  In the light source unit 2 according to the present embodiment, among the plurality of hooks, at least two hooks (second hooks 43) that are adjacent to each other with the protrusion 44 in the first direction are as follows. Preferably, it is configured. That is, the second hook 43 has a larger height dimension H2 from the front surface of the bottom plate 40 to the tip of the second arm 431 along the second direction than the other hooks (first hook 42). It is preferable to be configured to do so.

  As shown in FIG. 5C, since the substrate 31 bends near the protrusion 44, the substrate 31 is likely to lift from the front surface of the bottom plate 40, and when the LED module 3 is slid, the front end of the trunk portion becomes the edge of the first groove portion 310. It is easy to get caught. Therefore, if the light source unit 2 according to the present embodiment is configured as described above, the tip of the second body portion 430 of the second hooking portion 43 is less likely to be caught on the edge of the first groove portion 310, and workability is further improved. Improvements can be made.

  Further, in the light source unit 2 according to the present embodiment, the arm portion (second arm portion 431) of at least two hook portions (second hook portion 43) has a height along the second direction in a portion excluding the tip. It is preferable that the dimension is configured to be smaller than the height dimension of the tip.

  When the height dimension H2 from the front surface of the bottom plate 40 along the second direction to the tip of the second arm portion 431 is increased, if the entire second arm portion 431 is increased, the light emitted from the LED 30 is emitted from the second arm portion. It becomes easy to be interrupted by 431. Therefore, if the light source unit 2 according to the present embodiment is configured as described above, only the distal end portion of the second arm portion 431 is increased, so that the LED 30 is compared with the case where the entire second arm portion 431 is increased. The light emitted from the second arm portion 431 is not easily blocked by the second arm portion 431.

  Furthermore, in the light source unit 2 according to the present embodiment, the second groove 311 is preferably configured as follows. In other words, the second groove 311 is preferably configured such that the length dimension L1 along the first direction is longer than the length L2 of the protrusion 44 along the first direction. The second groove 311 has a length L1 along the first direction, a distance D1 between the second claw 432 and the second body 430 along the first direction, and a length L2 of the protrusion 44. It is preferable to be configured to be shorter than the sum.

  If the light source unit 2 according to the present embodiment is configured as described above, when the LED module 3 is attached to the support member 4, after the substrate 31 is sandwiched between the second claw portion 432 and the bottom plate 40, The protrusion 44 is inserted through the second groove 311 (see FIGS. 5C and 5D). Therefore, since the protrusion 44 is not inserted into the second groove 311 before the substrate 31 is sandwiched between the second claw portion 432 and the bottom plate 40, the workability can be further improved. . In addition, in a state where the LED module 3 is supported by the support member 4, the clearance (clearance) between the protrusion 44 and the second groove 311, the body (the first body 420 and the second body 430), and the first A clearance (clearance) with the groove 310 is ensured. Therefore, even when the linear expansion coefficients of the substrate 31 and the support member 4 are different, it is possible to suppress the occurrence of defects (cracking, abnormal noise, etc. of the substrate 31) due to thermal expansion and contraction.

  In the light source unit 2 according to this embodiment, the amount of bending of the substrate 31 when the LED module 3 is attached to the support member 4 varies depending on the distance from the protrusion 44 to the second hooking portion 43. That is, as the distance from the protrusion 44 to the second hook 43 increases, the amount of bending of the substrate 31 decreases, and the conductor formed on the first surface of the substrate 31 and the LED 30 (the anode electrode and the cathode electrode thereof) are reduced. The stress applied to the joint portion (solder) can be reduced.
