Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a lighting device in which a plurality of lighting lamps are arranged in a long tubular globe.

[0002]

[Prior Art]

 With the redevelopment of cities in recent years, there has been much interest in the formation of comprehensive landscapes, and along with the underground embedding of electric wires, the design of street components has become complicated.

The same is true of a street lighting device, and in the past, a plurality of lighting lamps such as a silver mercury lamp are arranged in a cylindrical transmission globe to illuminate the entire columnar body, and particularly a long lighting structure. A light fixture has been proposed and is used as a symbol light at urban intersections and the like.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional lighting device, in order to illuminate the entire columnar body by the lighting lamp installed through the tubular transmission globe, it is necessary to internally install a large number of lighting lamps. In addition to making the maintenance and inspection and replacement of the bulb complicated, the light source bulb replacement cost and running costs such as electricity bills also increased.

The present invention has been made in view of the above problems, and reduces the number of illumination lamps included in an illumination device and effectively illuminates the entire exterior transmission globe. It is an object of the present invention to provide a lighting device of the above.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the lighting apparatus according to the present invention has a plurality of illuminating lamps facing upward with a predetermined space between two columns that are erected on a base plate, and at least the outer periphery of the illuminating lamp is fixed. The gist is that the back side or the left and right side surfaces are covered with a plurality of permeation gloves formed so that the diameter gradually decreases upward.

A plurality of pairs of upper and lower illuminating lamps whose irradiation directions are opposed to each other can be arranged between the two columns, and a transmission globe covering at least a portion corresponding to the illuminating lamp arrangement portion is provided. It can also be configured so that it can be opened and closed on the outside and can serve as an inspection section for lighting.

Further, the inner surface of the transmission globe is provided with a light diffusing structure such as unevenness for diffusing and reflecting the irradiation light of the illumination lamp to the outside of the transmission globe, and further guiding light between the light sources of the illumination lamp which are vertically opposed to each other. It is also possible to interpose the body between the illuminating lamps and increase the luminous efficiency.

[0009]

[Action]

 According to the above configuration, the light emitted by the upwardly directed illumination lamp illuminates the inner surface of the transmission globe that is inclined upward at an appropriate angle. The entire illuminating device configured to have a length is illuminated. Further, when the light diffusing structure or the light guide body is configured, the luminescent effect of the transmission globe can be further enhanced, so that the symbol property of the illuminating device is improved. When performing maintenance and inspection work on the light source of the illumination lamp, the necessary work can be performed by opening the transparent glove that covers the inspection opening.

In this embodiment, the struts 1 and 1 are each formed of a square pipe material or the like (in the illustrated example, two round pipe materials 1a and 1a are welded and integrated). Are installed horizontally over a plurality of stages to fix the distance between the support columns 1 and 1, and at the outer periphery of the support columns 1 and 1, the constituent parts of the support rods 4 and 4 above. The outer frame 5, 5 ... These outer frames 5 and 5 are formed in a perfect circle shape surrounding the columns 1 and 1 in the bottom plan view, and gradually deform to an elliptical shape on the front or back side or the left and right side surfaces as they go upward. The short diameter side is configured to have a small diameter. Reference numeral 6 is a transparent globe that is attached to each of the sections formed by the columns 1, 1 and the outer frames 5, 5, ... To form an illuminating section. The shape of the outer frame 5, 5 ,. Corresponding to, the outer shape is inclined upward toward the vertical axis.

The above-mentioned transmission gloves 6, 6 ... Are made of a semi-cylindrical body such as frosted glass whose inner surface is frosted, milky white polycarbonate, etc., and are formed in the same step between the outer frames 4, 4. It has a shape that is divided into two parts so that it is on the front side and the back side, or on the left side and the right side in the compartment, and at least one of the transmission gloves 6 is formed by the hinge 7 configured outside the columns 1 and 1 above. It is openably and closably supported so that the other side can be appropriately opened to the outside. Then, the transparent gloves 6 and 6 are opened for each section so that the maintenance and inspection work can be performed on the plurality of illumination lamps 8a and 8b mounted between the columns 1 and 1 ... Other components. Has become. Reference numerals 9, 9 ... Are opening / closing screws for fixing the other side of the transparent 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. Further, reference numerals 10, 10, ... Are decorative edges that reinforce the outer circumference of the transparent gloves 6, 6.

In the present embodiment, the lighting lamps 8a, 8b, ... Are composed of a plurality of lighting lamps 8a facing upward and a lighting lamp 8b facing downward at a predetermined interval between the columns 1 and 1. And a pair of upper and lower illumination lamps 8a and 8b are arranged at least one pair. The radiant light flux of the illuminating lamp 8a directed upwards illuminates the inner surfaces of the above-mentioned transmission globes 6, 6 ... At an angle, and effectively shines the transmission globes 6, 6 from the inside. It is also possible to substitute the reflecting lamp 11 for the downward facing illumination lamp 8b arranged at the top.

It is possible to further improve the illumination effect of the transparent gloves 6, 6 ... By forming unevenness or other light diffusion structure (not shown) on the inner surface of the transparent gloves 6, 6. Further, as shown in FIG. 10, the light guide 12 may be interposed between the light sources of the illumination lamps 8a and 8b facing each other in the vertical direction to enhance the illumination efficiency of the transmissive gloves 6, 6.

In the lowermost section, inspection windows 14 and 14 that can be opened and closed by inspection doors 13 and 13 are configured, and a structure for performing maintenance and inspection of the illumination lamp 8 and a lighting circuit of the illumination lamp 8 and the like can be performed. It has become. Reference numeral 14 is an eyebolt detachably attached to the upper ends of the columns 1 and 1.

[Effect of the device]

 Since the lighting device according to the present invention is configured as described above, it is possible to illuminate the entire long columnar body with a small number of lighting lamps. Therefore, when it is used as a street light, sufficient luminous intensity on the road surface can be obtained. Not only will it be obtained, but the variety of designs will also increase, and maintenance and inspection of the lamps and replacement of the light source can be carried out easily, and the cost of replacing the light source and running costs such as electricity bills will rise sharply. The practical effect after implementation of the present invention, such as being able to hold down, is extremely large.
