Thereby, the fixture main body 2 (lighting fixture 1) is supported by the pole P (refer FIG. 20).

  In the attachment form (third attachment form) of this example, the attachment surfaces 61a (surfaces attached to the attachment seat 221 of the instrument body 2) of the pair of first vertical attachment flanges 61, 61 are cylindrical portions 60. Is inclined 5 ° with respect to a plane orthogonal to the cylindrical axis C2 (inclined 5 ° obliquely upward from the front side to the rear side of the lighting fixture 1). On the other hand, the upper surface 221 a of the mounting seat 221 to which each first vertical mounting flange 61 is attached is inclined 10 ° obliquely upward from the front side to the rear side of the instrument body 2. Therefore, the angle of the front surface (light emitting surface) of the front glass plate 31 of the lighting fixture 1 with respect to the cylindrical axis C2 (the center (vertical line) of the pole P) of the cylindrical portion 60 is 105 °. That is, the elevation angle of the luminaire 1 is 15 ° (see FIG. 20).

[Horizontal mounting]
Next, an example of attaching the lighting fixture 1 to the arm A will be described with reference to FIGS. 3 to 14, 21, and 22.

  First, each mounting surface of the pair of lateral mounting flanges 63, 63 in a state in which the cylindrical portion 60 of the support 6 is directed sideways (a state in which the end surface to which the numeral of the cylindrical portion 60 is attached is directed frontward). 63a is respectively aligned with the upper surfaces 221a of the pair of mounting seats 221 and 221 of the instrument body 2, and the bolt insertion holes 63b of the pair of lateral mounting collars 63 and 63 are respectively female threads of the pair of mounting seats 221 and 221. Align with the hole 221b (see FIG. 21A).

  In this state, the bolts 71 are inserted into the bolt insertion holes 63b of the pair of lateral mounting collars 63, 63, and the bolts 71 are screwed into the female screw holes 221b of the mounting seat 221, respectively. It is attached to the main body 2 (see FIG. 21B).

  Thereafter, with the distal end portion of the arm A inserted into the cylindrical portion 60 of the support 6 from the rear side, the bolt 72 is screwed into the female screw hole 60a of the wall of the cylindrical portion 60, whereby the arm A and the support 6 And Thereby, the fixture main body 2 (lighting fixture 1) is supported by the arm A (refer FIG. 22).

  In the mounting mode (fourth mounting mode) of this example, the mounting surfaces 63a (surfaces mounted on the mounting seat 221 of the instrument main body 2) of the pair of lateral mounting collars 63, 63 are the cylindrical shafts of the cylindrical unit 60. It is inclined 10 ° with respect to the plane along C2 (inclined 10 ° obliquely upward from the front side to the rear side of the luminaire 1). On the other hand, the upper surface 221 a of the mounting seat 221 to which each lateral mounting flange 63 is attached is inclined 10 ° obliquely upward from the front side to the rear side of the instrument body 2. Therefore, the front surface (light emitting surface) of the front glass plate 31 of the luminaire 1 is configured along the cylindrical axis C2 (center C4 of the arm A) of the cylindrical portion 60 (see FIG. 22). In addition, when the front-end | tip part of the arm A inclines 5 degrees, for example with respect to a horizontal surface, the elevation angle of the lighting fixture 1 will be 5 degrees.

<Effect>
As described above, according to the luminaire 1 of the present embodiment, when the luminaire 1 is attached to the pole P, one attachment tool 6 is rotated around the cylindrical axis C2 of the cylindrical portion 60 and attached (attachment). By changing the first to third embodiments, the angle of the front surface of the front glass plate 31 of the instrument body 2 with respect to the cylindrical axis C2 of the cylindrical portion 60 (the center C2 of the pole P), that is, the elevation angle of the luminaire 1 is 5 °. Three types of 10 ° and 15 ° can be set. Moreover, the attachment to the pole P and the attachment to the arm A of the lighting fixture 1 in such a form can be handled by one support tool 6. Thereby, it is possible to reduce the die cost and the parts inventory and simplify the parts management.

-Other embodiments-
In addition, embodiment disclosed this time is an illustration in all the points, Comprising: It does not become a basis of limited interpretation. Therefore, the technical scope of the present invention is not interpreted only by the above-described embodiments, but is defined based on the description of the scope of claims. Further, the technical scope of the present invention includes all modifications within the scope and meaning equivalent to the scope of the claims.

  For example, in the above embodiment, the elevation angle of the luminaire 1 is not limited to 5 °, 10 °, and 15 °, and any other plural (three or more types) elevation angles may be set. . Moreover, although the example in the case of setting the elevation angle of the lighting fixture 1 to three types of 5 °, 10 °, and 15 ° has been described, the present invention is not limited to this, and the elevation angles of four or more types of the lighting fixture 1 are described. May be set.

  In the above embodiment, the example in which the present invention is applied to the road lighting apparatus has been described. However, the present invention is not limited to this, and the lighting apparatus for other uses can be used as long as the lighting apparatus can be attached to the pole and the arm. The present invention can also be applied to.
