BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole-mounted illuminator in which a lamp having a built-in light source is mounted on an upper end of a pole, and more particularly to a structure in which a lamp is mounted on an upper end of a pole.

[0002]

2. Description of the Related Art Conventionally, in a lighting device of this type, when a lamp concrete is attached to an upper end of a pole, FIG.
(A) or as shown in FIG. 7 (b). FIG.
2A, a mounting tube 2 'hanging downward from the upper end of the lamp 1 is inserted into the upper end of the pole 3, and a mounting screw 4 is screwed into the mounting tube 2' from the outer surface of the pole 3. FIG.
2B, a mounting tube 2 'hanging downward from the upper end of the lamp 1 is fitted on the upper end of the pole 3, and a mounting screw 4 is screwed into the pole 3 from the mounting tube 2'.

[0003]

By the way, the head of the mounting screw 4 is exposed on the outer surface when mounted in this way. In particular, the size of the mounting screw becomes larger as the lamp 1 becomes larger, so that the head of the mounting screw 4 is apparent in appearance. There was a problem that the part was conspicuous and the appearance was poor. The present invention has been made in view of the above problems, and an object of the present invention is to provide a lighting device capable of attaching a lamp concrete to a pole with a good appearance without exposing a head of a mounting screw. It is in.

[0004]

In order to achieve the above object, the lighting device of the present invention comprises a lamp 1 having a built-in light source and a pole 3
In the pole-mounted lighting device mounted on the upper end of the pole 3, a concave groove 5 is vertically formed on the outer surface of the pole 3 and a lamp mounting hole 6 is formed near the upper end of the pole 3 at the bottom of the concave groove 5. The mounting leg 2 projecting downward from the lamp concrete 1 is inserted into the pole 3 so that the mounting leg 2 is
The mounting screw 4 is inserted into the lamp mounting hole 6 from the groove 5 and the mounting screw 4 is screwed to the mounting leg 2 along the inner surface of the groove 5, and the decorative cover 7 is covered over the opening of the groove 5 in the longitudinal direction. I wore it.

[0005]

[Function] The lamp concrete 1 is arranged at the upper end of the pole 3 and the lamp concrete 1 is arranged.
The mounting screw 2 is inserted into the pole 3 and the mounting screw 4 is inserted from the lamp mounting hole 6 of the concave groove 5 and the mounting screw 4 is screwed into the mounting leg 2, and the decorative cover 7 is inserted into the concave groove 5.
The lamp 1 can be attached to the pole 3 by covering the lamp 3 in the longitudinal direction. By mounting in this manner, the mounting screw 4 can be mounted with good appearance so that the mounting screw 4 is not visible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS First, the embodiment shown in FIGS. 1 to 4 will be described. The lamp concrete 1 is formed by housing a lamp 9 serving as a light source inside a casing 8. The outer periphery of the lamp 9 is a protection net 10
It is enclosed in. The casing 8 is provided with a light transmitting window 11 for transmitting the light of the lamp 9. A pair of mounting legs 2 are hung from the lower end of the casing 8 of the lamp concrete 1, and a screw hole 12 is formed in the mounting leg 2. The pole 3 is in the shape of a hollow pipe that is long in the vertical direction, and has a cross-sectional shape substantially the same as the cross-sectional shape of the casing 8 of the lamp 1. On both sides of the pole 3, concave grooves 5 having a U-shaped cross section are formed in the longitudinal direction, and locking protrusions 13 are formed in the vicinity of the opening of the concave grooves 5 so as to face each other in the longitudinal direction. It is formed. A lamp mounting hole 6 is provided near the upper end of the pole 3 and at the bottom of the concave groove 5.
Has been perforated. The packing 14 for sealing between the lamp concrete 1 and the upper end of the pole 3 is formed in a shape along the sectional shape of the pole 3. The decorative cover 7 is a long and narrow plate having a width substantially equal to the width of the concave groove portion 5, and a pattern unevenness 15 is formed on an outer surface as needed.

When the lamp 1 is mounted on the pole 3, the following operation is performed. The lamp concrete 1 is arranged on the upper end of the pole 3, and the mounting leg 2 of the lamp concrete 1 is
Are made to correspond to the inside of the pole 3, the mounting leg 2 is made to correspond to the inner surface of the concave groove portion 5, and the screw hole 12 and the lamp mounting hole 6 are matched. In this state, the mounting screw 4 is inserted from the lamp mounting hole 6, the mounting screw 4 is screwed into the screw hole 12, and the lamp 1 is fixed to the upper end of the pole 3. Next, the decorative cover 7 is disposed so as to extend in the longitudinal direction along the opening of the concave groove portion 3, and the decorative cover 7 is attached by locking the side edges of the decorative cover 7 to the locking ridges 13. At this time, the decorative cover 7 may be fixed to the concave groove portion 3 with a cover mounting screw. The lighting device of the present embodiment is used as a pole of a fence,
The end of the horizontal lattice 16 of the fence is connected to the pole 3.

FIGS. 5A and 5B show an embodiment in which the type of lamp concrete 1 is different. The casing 8 of the lamp concrete 1
Is formed in a horizontal T-shape by a vertical cylindrical body 8a and a horizontal cylindrical body 8b, and a lamp 9 is provided in the horizontal cylindrical body 8b. The structure for attaching the lamp concrete 1 to the pole 3 is the same as in the above embodiment. A mounting bracket 17 is mounted at an appropriate position in the concave groove 3, and the decorative cover 7 is fixed to the mounting bracket 17 with a cover mounting screw 18. If the cover mounting screw 18 has a special head that cannot be operated with a normal tool, the cover mounting screw 18 is removed by mischief and the decorative cover 7 cannot be removed.

FIG. 6 shows another embodiment in which the type of the lamp 1 is different. A lamp 9 is provided inside a casing 8 of the lamp 1. The structure for attaching the lamp concrete 1 to the pole 3 is the same as in the above embodiment.

[0010]

According to the present invention, as described above, a groove is formed on the outer surface of the pole vertically and a lamp mounting hole is formed at the bottom of the groove near the upper end of the pole, and the light fixture mounting hole extends downward from the lamp. Insert the protruding mounting leg into the pole, align the mounting leg with the inner surface of the groove, insert the mounting screw from the groove into the lamp mounting hole, screw the mounting screw to the mounting leg, and open the groove. Because the decorative cover is attached to the pole in the longitudinal direction, the mounting screws for attaching the lamp concrete to the pole are not covered with the decorative cover and can be seen externally, making it possible to have a neat appearance. Since the screws are not visible on the exterior, they can be mounted using mounting screws according to the required strength, so that the light concrete can be firmly mounted on the pole. By changing the color and surface texture of the decorative cover, it is possible to increase the design variation for poles of the same cross-section because it is composed of separate members, and it is not possible to operate with a normal tool as a screw to attach the decorative cover If it is used, the decorative cover cannot be easily removed, and it is possible to prevent tampering with the mounting screws for attaching the lamp concrete being loosened.
