  Next, installation of the lighting fixture 10 will be described.

  As shown in FIG. 5, with only the reflector 21 removed from the instrument body 17, the instrument body 17 is inserted into the embedding hole 13 of the ceiling plate 12, and the instrument mounting portions 45 on both sides of the instrument support 18 (attachment holes The tip of the suspension bolt 14 is passed through 46), and a nut 70 is screwed on the tip of the suspension bolt 14 as a mounting tool, and the instrument support 18 is attached to the suspension bolt 14.

  This operation is performed between the mounting frame 20 and the instrument body 17. At this time, as shown in FIG. 4, the distance L1 in the first direction a between the instrument main body 17 and the attachment frame 20 is in the second direction b between the reflector attachment portion 51 and the attachment frame 20. The relationship is wider than the interval L2. Therefore, a large working space 71 is secured between the mounting frame 20 and the tool main body 17 so as to face the tool mounting portion 45 of the tool support 18, and the work can be easily performed.

  In addition, when inserting the instrument main body 17 into the embedding hole 13 of the ceiling plate 12, the power supply line wired in advance on the ceiling side is connected to the power supply unit 26.

  Then, after the installation of the instrument body 17, the reflector 21 is inserted into the inside of the mounting frame 20, and the reflector 21 is attached to the reflector mounting portion 51 by the screw 67.

  Generally, when attaching the reflector 21 to the reflector attaching portion 51 of the reflector attaching body 19, the reflector attaching body 19 is made into a square projecting in four directions from the appliance main body 17, and the reflector attaching at the center of each of the four sides In many cases, one part 51 is provided. However, in this case, the working space 71 between the mounting frame 20 facing the tool mounting portion 45 of the tool support 18 and the tool main body 17 tends to be narrow.

  In the luminaire 10 of this embodiment, the reflector attachment 19 is rectangular, and in the second direction b intersecting with the first direction a of the instrument body 17 in which the instrument attachment 45 of the instrument support 18 is located. By facing the longitudinal direction of the reflector attachment body 19 and providing the reflector attachment portions 51 at both ends in the longitudinal direction of the reflector attachment body 19, the attachment facing the instrument attachment portion 45 of the instrument support 18 is provided. The working space 71 between the frame 20 and the instrument body 17 can be made wide.

  Therefore, according to the lighting device 10 of the present embodiment, a wide working space 71 is secured between the mounting frame 20 and the device main body 17 so as to face the device mounting portion 45 of the device support 18. Can be easily performed.

  Moreover, since the fixture attachment portion 45 and the reflector attachment portion 51 are provided in the direction intersecting with the fixture main body 17, the support balance is good, and the posture in the installation state of the lighting fixture 10 can be stabilized. .
