BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a lighting device in which a plurality of lighting lamps are arranged in a long cylindrical glove.

[0002]

2. Description of the Related Art In recent years, attention has been paid to the formation of a comprehensive landscape with urban redevelopment, and the design of street components has become more complicated with the burial of electric wires and the like.

[0003] The same applies to lighting devices for streets.
Conventionally, in particular, a long lighting fixture having a structure in which a plurality of lighting lamps such as a mercury lamp are arranged in a cylindrical transmission globe to illuminate the entire columnar body has been proposed, and is used as a symbol lamp at an urban intersection or the like. I have.

[0004]

However, in the above-mentioned conventional lighting device, in order for the entire columnar body to be illuminated by a built-in lighting lamp through a cylindrical transmission glove,
A large number of illumination lamps need to be installed in the interior, which not only complicates the maintenance and inspection and replacement of the light source bulb, but also increases the cost of replacing the light source bulb and the running cost such as electricity. Was.

[0005] The present invention has been made in view of the above-mentioned problems, and is intended for a street, in which the number of illuminating lamps included in an illuminating device can be reduced and the whole of the externally mounted transmissive globe can be effectively illuminated. It is an object to provide a lighting device.

[0006]

In order to achieve the above-mentioned object, an illumination device according to the present invention is arranged such that an irradiation direction is opposed at a predetermined interval between two columns erected on a base plate.
And a pair of upper and lower illuminating lamps is disposed, and the outer periphery of the illuminating lamp is covered with a plurality of transmissive gloves formed such that the front rear side or the left and right side surfaces gradually become smaller in diameter upward. It is an abstract.

Further, transmission globe covering the portion corresponding to the at least lamp arrangement unit is openably mounted to the outside, it can also be configured to be inspected part with respect to the illumination lamp.

On the inner surface of the transmissive globe, there is formed an unevenness or other light diffusing structure for diffusing and reflecting the irradiation light of the illumination lamp to the outside of the transmissive globe. May be interposed to increase the luminous efficiency between the illumination lamps.

[0009]

According to the above construction, the irradiation light facing Ri by the illuminating lamp which is arranged in the upper and lower pair is inclined at an appropriate angle upward
In order to efficiently illuminate the inner surface of the long transmission globe, the lighting effect of the transmission globe on a portion away from the illumination lamp is enhanced, and the entire long illumination device is illuminated.
Further, when a light diffusing structure or a light guide is formed, the luminous effect of the transmission glove can be further enhanced, so that the symbolism of the lighting device is improved. When performing maintenance work on the light source of the illuminating lamp, the necessary work can be performed by appropriately opening the transmission glove covering the inspection opening.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the lighting device according to the present invention will be described below with reference to the drawings. 1 to 9,
Reference numerals 1 and 1 denote support columns that are planted and fixed between the top plate 2 and the base plate 3 at equal intervals. In this embodiment, each of the columns 1 and 1 is a square pipe material or the like (in the illustrated example,
Two round pipe members 1a, 1a are welded and integrated), and poles 4, 4,... Are fixed, and the poles 4, 4.
, Which correspond to the components of the lighting device, and are fixedly connected to each other to form the outer frame of the lighting device. These outer frames 5 and 5 are formed in a perfect circle shape surrounding the columns 1 and 1 in a plan view of the lowermost stage, and are gradually deformed into an elliptical shape on the front back side or the left and right side sides as going upward, The short diameter side is configured to have a small diameter. Reference numeral 6 denotes a transmission glove mounted on each section formed by the columns 1, 1 and the outer frames 5, 5,... To form a lighting unit, and has a shape on the minor diameter side of the outer frames 5, 5,. , An outer shape inclined upward toward the vertical axis is formed.

The transmission gloves 6, 6,... Are made of a semi-cylindrical body made of, for example, frosted tempered glass, milky white polycarbonate or the like, and are formed in the same step between the outer frames 4, 4,. At the front side and the back side, or the left side and the right side, and at least one of the transmission gloves 6 can be freely opened and closed by a hinge 7 formed outside the above-mentioned columns 1 and 1. , So that the other side can be opened outward as appropriate. Then, the transmission gloves 6 and 6 are opened for each section so that maintenance and inspection work can be performed on the plurality of illuminating lights 8a, 8b... Has become.
Reference numerals 9, 9... Are opening / closing screws for fixing the other side of the transmission gloves 6, 6,..., Such as the front side and the back side, or the left side and the right side, to the outside of the columns 1, 1. Also, 10,10
... are decorative edges for reinforcing the outer periphery of the transmission gloves 6, 6,.

In this embodiment, the illumination lamps 8a, 8b
Are a plurality of lighting lamps 8a facing upward and a pair of lighting lamps 8b facing downward with a predetermined interval between the columns 1, 1, and are arranged to face each other so as to form a pair of upper and lower lights. At least one pair of the lamps 8a and 8b is arranged. The luminous flux of the upwardly directed illumination lamp 8a irradiates the inner surfaces of the transmission globes 6, 6,... At an angle, and effectively shines the transmission gloves 6, 6 from the inside. It should be noted that the illumination lamp 8b which is disposed at the top and faces downward.
Can be substituted by the reflecting mirror 11.

The illumination effect of the transmission globes 6, 6,... Can be further improved by forming unevenness or other light diffusion structures (not shown) on the inner surfaces of the transmission gloves 6, 6. Further, as shown in FIG. 10, the light guide 12 can be interposed between the light sources of the illumination lamps 8a and 8b opposed vertically to increase the illumination efficiency of the transmission globes 6, 6,.

The lowermost section is constructed so that it can be inspected by inspection doors 13 and 13 which can be opened and closed, and has a structure capable of performing maintenance and inspection of the illumination lamp 8 and a lighting circuit of the illumination lamp 8. ing. Reference numeral 14 denotes an eyebolt that is detachably attached to the upper ends of the columns 1 and 1.

[0015]

[Effect of the Invention] Since the lighting device according to the present invention is configured as described above, the entire columnar body constituted by a long length can be illuminated by a small number of lighting lamps. In addition to obtaining a luminous intensity of the road surface, the variation of the design becomes large, and the maintenance and inspection of the lighting, the replacement of the light source, etc. can be easily carried out, and the running cost such as the replacement cost of the light source and the electricity bill. The practical effect after the implementation of the present invention is extremely large, for example, it is possible to suppress a rise in cost.
