(2-2-6) Procedure for Assembling Light Source Unit Next, the procedure for assembling the light source unit 2 will be described. However, the assembly procedure described below is just an example, and the order of some procedures may be changed.

First, an operator who performs the assembly operation places the insulating sheet 21 on the mounting surface 50 of the mounting member 5 . The insulating sheet 21 is formed in a sheet shape from a synthetic resin such as PET (polyethylene terephthalate). The insulating sheet 21 is provided with a plurality of holes corresponding one-to-one with the plurality of screw holes 51 provided in the mounting surface 50 .

The operator places the LED modules 3 on the insulating sheet 21 and places the support members 8 one by one so as to overlap the plurality of through holes 310 of the substrate 31 . The support member 8 is made of an electrically insulating material, such as PBT (polybutylene terephthalate), and is shaped like a truncated cone and has a hole penetrating through the center. Note that the diameter of the bottom surface of the support member 8 is larger than the inner diameter of the through hole 310 of the substrate 31 .

An operator screws the screw 52 into the threaded hole 51 of the mounting member 5 through the hole of the supporting member 8 . Therefore, the LED module 3 is attached to the mounting surface 50 of the mounting member 5 via the support member 8 and the screws 52 .

An operator pulls out the output cable 20 to the mounting surface 50 side through the central cable insertion hole of the mounting member 5 and connects the output cable 20 to the connector 32 of the LED module 3 .

The operator mounts the sealing member 6 on the peripheral portion 42 of the light distribution control member 4 by inserting the peripheral portion 42 into the groove 64 of the sealing member 6 . After that, the worker places the light distribution control member 4 with the sealing member 6 mounted thereon on the mounting surface 50 (see FIG. 5), and then covers the sealing member 6 with the frame 7 from the front.

Finally, the operator screws the screws 72 into the screw holes 51 of the mounting surface 50 one by one through the screw holes 700 of the front wall 70 . As a result, the frame 7 is fixed to the mounting member 5 , and the peripheral portion 42 of the light distribution control member 4 is sandwiched between the frame 7 and the mounting surface 50 with the seal member 6 interposed therebetween. is attached to the attachment member 5 . A gap between the mounting surface 50 and the peripheral portion 42 is sealed by the sealing member 6 . In addition, since the escape portions 43 and 65 are provided in the peripheral portion 42 of the light distribution control member 4 and the sealing member 6 respectively, the mounting member 5 can be mounted while preventing the peripheral portion 42 and the sealing member 6 from coming into contact with the screw 72 . can be downsized in the vertical and horizontal directions.

The assembly work of the light source unit 2 is completed by the above procedure.

(2-3) Procedure for Assembling Lighting Apparatus Next, the procedure for assembling the lighting apparatus A1 will be described. However, the assembly procedure described below is just an example, and the order of some procedures may be changed.

For example, an operator places two light source units 2 side by side on a workbench and attaches one fixing table 10 to each of the left and right ends of the two light source units 2 . That is, the operator attaches each fixing base 10 to the left and right ends of the two light source units 2 with two screws 100 inserted through the two screw holes of each fixing base 10 . Thus, the two light source units 2 are fixed to the pair of fixing bases 10, and are supported by the fixture body 1 (the pair of fixing bases 10) so as to be vertically aligned (see FIG. 1).

After connecting the output cables 20 of the two light source units 2 to the terminal block in the box body 130 , the operator closes the opening of the box body 130 with the lid 131 . Note that the lid 131 is fixed to the box body 130 by screwing.

The above procedure completes the assembly work of the lighting fixture A1.

(3) Advantages of the Embodiments As described above, the luminaire A1 combines the function of the conventional optical component (function of controlling light distribution) and the function of the front cover (function of protecting the optical component) into one component (distribution function). Since it is held by the light control member 4), the workability of the assembly work can be improved by reducing the number of parts. Furthermore, in the lighting fixture A1, the position regulating portion 44 of the light distribution control member 4 is sandwiched between the mounting surface 50 and the frame 7 without the sealing member 6 (see FIG. 6). The distance of the control member 4 (the distance in the front-rear direction) is defined by the height of the frame 7 (the width of the side walls 71 in the front-rear direction). Therefore, in the lighting fixture A1, variations in the distance between the LED module 3 and the light distribution control member 4 are less likely to occur. As a result, the lighting fixture A1 can improve the workability of the assembly work and suppress the deterioration of the light distribution characteristics.

In the lighting device A1, the sealing member 6 includes a first sealing portion 61 sandwiched between the peripheral edge portion 42 and the frame body 7, a second sealing portion 62 sandwiched between the peripheral edge portion 42 and the mounting surface 50, have Thus, in the lighting fixture A1, the seal member 6 can reliably seal the gap between the peripheral edge portion 42 and the frame body 7 and the gap between the peripheral edge portion 42 and the mounting surface 50, respectively.

Furthermore, in the luminaire A1, since different portions of the sealing member 6 and the frame 7 are fixed to the mounting surface 50 by a plurality of fixing members (screws 72), the sealing member 6 is substantially evenly compressed to improve sealing performance. can be planned. However, the fixing member is not limited to the screws 72, and for example, instead of the screws 72, crimping rivets or the like may be used.

Furthermore, in the lighting device A1, the plurality of position regulating portions 44 of the light distribution control member 4 are arranged between the plurality of fixing members (screws 72) (see FIGS. 4 and 5). Therefore, the sealing member 6 receives force from the frame 7 on both sides of the position restricting portion 44 . Therefore, in the lighting device A1, it is possible to improve the sealing performance of the sealing member 6 in the vicinity of the position restricting portion 44. FIG.

In addition, in the lighting fixture A1, the light distribution control member 4 has the escape portion 43 that escapes the peripheral portion 42 from the plurality of fixing members (screws 72). 4 can be made smaller in the vertical and horizontal directions.

Furthermore, in the lighting fixture A1, the seal member 6 has the relief portion 65 for escaping the plurality of fixing members (screws 72). Miniaturization can be achieved.
