DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole used for street lights and the like.

[0002]

2. Description of the Related Art In order to effectively utilize the space in a pole, it has been considered to house electric components such as a breaker and a time switch.

[0003]

However, moisture is easily generated in the pole and dew condensation occurs.
As shown in (1), it has to be housed in a closed box 50 such as a standard or custom joint box and installed in the pole 51. 52 is a ballast.

Accordingly, an object of the present invention is to provide a pole on which a non-waterproof electrical component that can be protected from moisture without being housed in a closed box can be directly installed.

[0005]

According to a first aspect of the present invention, there is provided a pole having a cylindrical shape having an upper vent and a lower vent, and communicating between the upper and lower vents. A means for convection of air is provided therebetween.

According to the pole of the first aspect, since the moisture inside the pole can be removed by means of convection of the air, the conventional non-waterproof electric parts are housed in a closed box such as a joint box. It can be installed directly in the pole without the need. As a result, the cost can be reduced by eliminating the need for a closed box, and a large number of breakers and the like can be stored in the main pole, and the function of, for example, a lighting control panel can also be performed.

According to a second aspect of the present invention, in the first aspect, at least one of the upper ventilation port and the lower ventilation port has a rainproof structure, and the means is a heat source of a lighting fixture.

[0008] According to the pole described in claim 2, according to claim 1
In addition to the same effects as above, even if installed in places exposed to the weather, rain can be protected inside, and lighting equipment is used as a means,
It can be used for lighting poles.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG. That is, the pole has an upper ventilation port 1 and a lower ventilation port 2 and is a cylindrical pole 3 communicating between the upper ventilation port 1 and the lower ventilation port 2, and means for convection of air between the upper ventilation port 1 and the lower ventilation port 2. 4 are installed.

In the embodiment, the pole 3 comprises a cylindrical storage part 5 and a cylindrical illumination part 6 installed so as to communicate with the upper end of the storage part 5. The lower end of the storage unit 5 is installed and erected on the ground, floor, or the like. The lower ventilation port 2 is provided near the lower end of the storage section 5. This lower vent 2 is shown in FIG.
As shown in (b), a rag 7 is provided on the front side, a rain shield 8 is provided as a rain-proof structure on the inside, and an insect-proof sheet 9 formed of a mesh is provided on the inside. A breaker, a time switch, and the like, for example, are installed as non-waterproof electrical components 10 inside the lower ventilation port 2 in the storage unit 5.
In addition, a light source 11 of a lighting fixture that also serves as a convection means 4 is installed at the upper end side of the storage unit 5. An instrument body 15 including a lamp socket 13 and a reflector 14 is attached to an attachment portion 12 provided in the storage portion 5, and the light source 1 is attached to the lamp socket 13.
1 is attached.

The lighting fixture is connected to a power supply (not shown).

The illumination section 6 is a cylindrical body using a milky white acrylic pipe, and the lower end thereof is connected to the upper end of the storage section 5.
An upper vent 1 is formed at the upper end. The upper ventilation opening 1 has a roof portion 1 which is capped at the upper end of the illumination portion 6 with a gap therebetween.
6 is provided, and the lower edge peripheral portion of the roof portion 16 is located below the upper ventilation port 1 to form a rainproof structure.

When the lighting equipment is turned on, the light of the light source 11 is transmitted directly or reflected by the reflecting plate 14 to pass through the lighting section 6 and diffusely transmitted to the outer surface, thereby brightening the surroundings. Further, the air in the storage section is heated by the lamp light heat of the luminaire, convection occurs, rises as shown by the arrow, and exits through the upper vent 1.
At the same time, outside air enters into the inside through the lower ventilation port 2 and
And the inside of the illumination part 6 causes the convection of the updraft.

According to the first embodiment, since the moisture inside the pole can be removed by the means 4 for convection of the air, the conventional non-waterproof electric parts are housed in a closed box such as a joint box. It can be directly installed in the pole 3 without performing. As a result, the cost can be reduced by eliminating the need for a closed box, and a large number of breakers and the like can be stored in the main pole, and the function of, for example, a lighting control panel can also be performed.

Further, by providing at least one of the upper ventilation port 1 and the lower ventilation port 2 with a rain-proof structure, even if the pole 3 is installed in a place where it is exposed to wind and rain, the inside can be protected from rain, and the means 4 can be illuminated Can be used for the pole 6 for lighting.

FIG. 2 shows a second embodiment of the present invention. That is, this pole is a street light, and the streetlight lighting device 17 is attached to the upper end of the pole 3. The pole 3 is provided with a gallery 7 at a position covering the lower vent on the lower side, and an upper vent 1 at the upper end.

Near the lower end of the pole 3, a lighting fixture 17 is provided.
And a mounting plate 18 to which two ballasts 19 and 20, a breaker and a time switch for the internal lamp are mounted, and a lamp (not shown) is arranged on the upper side thereof. A glove 21 in the form of a strip is provided. 22
Is a glove 21 made of, for example, a milky white acrylic material.
Is a flag pole, 23 is a flag, and 24 is a curved arm for mounting the lighting equipment 17.

The pole 3 illuminates the surrounding roads with the lighting fixture 17 and illuminates the flag 23 and the pole 3 through the globe 21 by turning on the lamp.

In the present invention, the means for convection of air may be a fan device.

[0020]

According to the pole of the first aspect, since the moisture inside the pole can be removed by means of convection of air, the conventional non-waterproof electric parts can be converted into a closed box such as a joint box. It can be installed directly in the pole without storage. As a result, the cost can be reduced by eliminating the need for a closed box, and a large number of breakers and the like can be stored in the main pole, and the function of, for example, a lighting control panel can also be performed.

According to the pole described in claim 2, according to claim 1,
In addition to the same effects as above, even if installed in places exposed to the weather, rain can be protected inside, and lighting equipment is used as a means,
It can be used for lighting poles.
