DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column-shaped illuminating lamp in which a lighting fixture is stored inside a hollow support.

[0002]

2. Description of the Related Art Gate lights, garden lights, street lights, etc.
Lighting fixtures may be stored inside hollow columns. Lighting equipment is equipped with lamps, ballasts, lighting tubes, automatic lighting devices, etc., which must be protected from water leakage. In addition, replacement of the lamp and periodic inspection of other members are required.

[0003] Such a lamp in which the front end surface of the column is closed with a cap has a simple appearance and is elegant. Furthermore, in order to make the column simpler in appearance, it is necessary to prevent the heads of bolts and screws used for mounting the internal members from being seen from the outside. In order to solve this, a vertical groove (longitudinal groove) is formed on the back of the column, the head of the bolt or screw is located at the bottom of this groove, and the vertical groove is covered with a perforated board to adjust the appearance I have. Also, by design, the upper part of the column is bent, and the tip is closed with a cap.

However, in a structure in which the tip of the column is closed with a cap, water is likely to leak from the contact portion between the column main body and the cap, particularly, the contact portion at the upper surface (back surface) of the column. In particular, in the case where the vertical groove is located on the upper surface of the pillar by bending, rainwater easily collects in the vertical groove even if the eyeboard is attached. In addition, the contact portion between the cap and the tip end surface of the support body is concave at the location of the vertical groove, so that water is more likely to leak.

[0005] Water leakage from the contact portion can be prevented by interposing a tight material in the contact portion or by providing a sealing material. Must be rebuilt every time the cap is removed to inspect the luminaire or replace the lamp.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lighting device in which a lighting device stored inside a hollow support is protected from water leakage by a structure of a cap.

In this state, the extension 18 of the cap 9 attached to the tip of the column main body 8b enters the vertical groove 12 and covers the tip of the vertical groove 12 (FIG. 7), and the guide piece 19 becomes the extension 1
8 is located below the position corresponding to both sides of the support body 8 and inside the support body 8b. The eye panel 10 is attached to the vertical groove 12 of the support body 8 (a, b), the support 5 is completed, and the illumination lamp 1 is completed. The eye panel 10 is mounted to conceal a screw appearing on the back surface of the column 5 or to conceal wiring using a vertical groove for the purpose of connecting members.

With the above structure, the danger of water leakage is considered at the contact portion between the column body 8b and the cap 9, particularly at the contact portion at the upper surface, and at the location of the vertical groove 12. The extension 18 of the cap 9 penetrates into the end of the cap to cover the contact portion, and water leakage from this contact portion is completely stopped. Rainwater that enters from the gap between the extension portion 18 and the eye panel 10 falls into the vertical groove 12 at a position away from the contact portion, and is guided downward by the vertical groove 12.

Rain water that has entered from the contact points s, s (FIG. 7) on both the left and right sides of the extension portion 18 leaks into the inside of the column body 8b. Is guided in the direction of both side walls of the column main body 8b along the bent shape, and is separated far from the lighting fixture 6. At this time, if the lighting fixture 6 is formed with the roof-shaped lamp pedestal 7, water leakage is prevented by this member, and it becomes more difficult to reach the lighting fixture 6. The water leak guided by the guide pieces 19 moves downward along the guide 15 and is discharged.

FIG. 6 shows another embodiment related to the guide 15. In the guide 15, the lower one of the upper and lower ridges forming the rail groove 14 is extended and bent upward.
Condensation water and water leakage that may accumulate in the rail groove 14 are prevented from entering the inside of the lamp base 7. In addition, with this shape, the mounting of the sliding rib 30 to the rail groove 14 is easy.

That is, the structure of the cap 9 prevents water from leaking to the lighting fixture 6.

The fluorescent lamp 25 can be replaced or the lighting fixture 6 can be replaced.
When checking the cap, loosen the fixing screw 34 and remove the cap 9
From the support body 8b. Then, the connecting bolt 31
The lamp base 7 can be pulled out of the support body 8a together with the luminaire 6 by the connection with the lighting device 6, so that replacement or inspection work can be performed in a wide environment. When the lighting fixture 6 is stored in the column body 8b after the work, the lamp pedestal 7 is pushed in, the cap 9 is fitted, and the fixing screw 34 is screwed in. If the fixing screw 34 is prevented from falling off by the E-ring as in the embodiment, the screw will not be lost during the work. Further, when the retaining screw 35 and the receiving screw 36 are provided, the lamp pedestal 7 does not fall off from the support main body 8b and the work is easy.

The above is an embodiment, and the present invention is not limited to the illustrated specific configuration. The connection structure between the cap 9 and the lamp pedestal 7 and the structure for fixing the cap 9 to the column body 8b may be based on reliable engagement means. The cross-sectional structure of the vertical main body 8a and the inclined main body 8b may be different with respect to the internal structure.

[0028]

According to the present invention, it is almost impossible for a lighting fixture disposed inside a hollow support to break down due to water leakage. Since water leakage is prevented by the cap fitting structure, the waterproof function does not deteriorate even when the cap is attached or detached. If the lower ridge forming the rail groove is extended and bent upward, it is possible to prevent dew condensation or water leak that may accumulate in the rail groove from entering the inside of the lamp pedestal.
When the cap and the lamp pedestal are connected, the luminaire can be pulled out of the column body together with the lamp pedestal, and the replacement, maintenance, and inspection of the lamp can be performed safely in a wide work space. After the work, when the lighting equipment is stored in the main body of the support, it is only necessary to push in, fit the cap, and fix the screws.
