FIG. 5 is a cross-sectional view of the module support 4 and the column 3c of the light-emitting device 1 according to Embodiment 1 as viewed from the direction of the device central axis (front end side) and a plane including the device central axis. As shown in FIG. 4, the attachment surface of the side surface portion of the module support 4 includes a plurality of first attachment surfaces 4a, a plurality of second attachment surfaces 4b, and a plurality of third attachment surfaces 4c. Each mounting surface is provided with a mounting hole for mounting the light source module 2 with a screw 5.

When the light source module 2 is attached to the third attachment surface 4c, it is as shown in FIG. The angle of the second mounting surface 4b with respect to the device central axis and the angle of the third mounting surface 4c with respect to the device central axis are preferably equal in size, but may be different.

The shape obtained by orthogonally projecting the actual outer shape of the module support 4 in the direction of the central axis of the apparatus may not be a perfect polygon, for example, a corner may be missing or a part of the side may be missing. .

  In the first embodiment, the first mounting surface 4a is parallel to the device central axis. However, in the present invention, the first mounting surface 4a may be inclined with respect to the device central axis.

  In the first embodiment, three types of mounting surfaces having different angles with respect to the apparatus central axis, that is, the first mounting surface 4a, the second mounting surface 4b, and the third mounting surface 4c are provided on the module support body 4, whereby the light source The mounting angle of the module 2 can be changed more variously. In particular, the mounting angle of the light source module 2 can be varied more variously because the third mounting surface 4c is inclined in the direction opposite to the second mounting surface 4b with respect to the central axis of the apparatus. However, in the present invention, the module support 4 may be provided with at least two types of attachment surfaces having different angles with respect to the central axis of the apparatus.

  As shown in FIG. 4, the first mounting surface 4a and the second mounting surface 4b are adjacent to each other in the direction of the apparatus central axis. By doing so, the width of the first mounting surface 4a (the length in the direction orthogonal to the apparatus central axis) and the width of the second mounting surface 4b (the length in the direction orthogonal to the apparatus central axis) are secured long. It is possible to improve the mounting rigidity of the light source module 2. The first mounting surface 4a and the third mounting surface 4c are adjacent to each other in the direction of the device central axis. By doing so, the width of the first mounting surface 4a (the length in the direction orthogonal to the device central axis) and the width of the third mounting surface 4c (the length in the direction orthogonal to the device central axis) are ensured long. It is possible to improve the mounting rigidity of the light source module 2.

By doing so, it is possible to avoid the second mounting surface 4b and the third mounting surface 4c from being aligned in the direction of the device central axis, so that the thickness of the module support 4 (the length in the direction of the device central axis) is reduced. It can suppress becoming large.

  When the position in the direction of the device central axis is the same as that of the second mounting surface 4b, the first mounting surface 4a and the second mounting surface 4b are alternately positioned in the circumferential direction with respect to the device central axis. Further, when the position in the direction of the device central axis is the same as that of the third mounting surface 4c, the first mounting surface 4a and the third mounting surface 4c are alternately positioned in the circumferential direction with respect to the device central axis. By doing so, it is possible to avoid the second mounting surface 4b and the third mounting surface 4c from being aligned in the direction of the device central axis, so that the thickness of the module support 4 (the length in the direction of the device central axis) is reduced. It can suppress becoming large.
