The upper part of the arc plate 70 is attached to the distal end portion of the upper horizontal member 62 via an L-shaped mounting bracket, and the lower portion of the arc plate 70 is attached to the distal end portion of the lower horizontal member 66 with an L-shaped mounting bracket. Is attached through.

  FIG. 8 is a schematic front view showing a part of the positional relationship between the second skeleton member 52 and the circular arc plate 70. Further, FIG. 9 shows the LED 18 and its mounting partner in a schematic perspective view. As shown in FIGS. 8 and 9, a plurality of arc plates 70 are provided, and are arranged in parallel around the axis of the column 14 (see FIG. 2). As shown in FIG. 9, a plurality of LEDs 18 are attached to a portion of the arc plate 70 facing the inner surface of the spherical portion 12 with a double-sided tape as an example.

  Although not shown in detail, the wiring of the LED 18 extends to the lower side of the spherical portion 12 through the inside of the column 14 shown in FIG. 3 and the like, and is connected to a power supply unit (not shown). Thus, the LED 18 is supplied with power from the power supply unit.

(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  In the light emitting spherical body 10 according to the present embodiment shown in FIG. 3 and the like, the spherical portion 12 whose inside is hollow is formed of polyethylene having light permeability. For this reason, such a spherical part 12 is hard to break compared with what was shape | molded with the acrylic etc. which have a light transmittance, for example, and its durability is high. In addition, a skeleton portion 16 constituting a skeleton of the spherical portion 12 is disposed inside the spherical portion 12. Thereby, the spherical part 12 is reinforced and is suitable for long-term installation.

  On the other hand, the spherical portion 12 is white, and a plurality of LEDs 18 attached to the skeleton portion 16 are arranged inside the spherical portion 12. For this reason, the spherical part 12 can be made to shine with the some LED 18 from the inside, without showing the inside of the spherical part 12 from the outside (or hardly showing). A part of the light is diffusely reflected inside the spherical portion 12 and then passes through the spherical portion 12. And in such a structure, even if the spherical part 12 is large-sized (for example, about 5 m in diameter), the whole spherical part 12 can be light-emitted.

  Further, in the present embodiment, the support column 14 having the center position of the spherical portion 12 as the axial center position in plan view is provided, and the support column 14 penetrates the lower end of the installed state of the spherical portion 12. And since the skeleton part 16 connects the spherical part 12 and the support | pillar 14, and the spherical part 12 is supported by the support | pillar 14, the spherical part 12 can be installed in the stable state.

  In the present embodiment, the plurality of first skeleton members 42 extend radially from the central portion of the spherical portion 12 to connect the support column 14 and the spherical portion 12. On the other hand, the plurality of second skeleton members 52 are linearly connected to each other around the central portion of the spherical portion 12 among the plurality of first skeleton members 42 and the pillars 14. They are arranged so as to form a regular polygon (more specifically, a regular octagon) around the center. A plurality of LEDs 18 are attached to a portion of the second skeleton member 52 facing the inner surface of the spherical portion 12. Therefore, the LED 18 is stably supported by the second skeleton member 52, and the distance between each LED 18 attached to the second skeleton member 52 and the inner surface of the spherical portion 12 can be made substantially equal.

  In addition, a plurality of arc plates 70 that are curved in an arc shape with the center of the spherical portion 12 as the center of the arc are arranged in parallel around the axis of the support column 14 in the skeleton portion 16. And as FIG. 9 shows, the some LED18 is attached to the opposing part with the inner surface of the spherical part 12 in the circular arc board 70. As shown in FIG. Therefore, the distance between each LED 18 attached to the arc plate 70 and the inner surface of the spherical portion 12 can be made equal.

  In the present embodiment, as shown in FIG. 7, an upper horizontal member 62, an intermediate horizontal member 64, and a lower horizontal member 66 are provided for supporting the arc plate 70. The upper horizontal member 62 is disposed at a height position above the center height position of the spherical portion 12 inside the spherical portion 12, and the base end portion is attached to the support column 14 and extends horizontally. On the other hand, the intermediate horizontal member 64 is arranged at the center height position of the spherical portion 12 inside the spherical portion 12, and the base end portion is attached to the column 14 and extends in the same direction as the upper horizontal member 62. The extension length from the column 14 is set to be longer than the extension length from the column 14 in the upper horizontal member 62. Further, the lower horizontal member 66 is disposed in a height position below the center height position of the spherical portion 12 inside the spherical portion 12, and a base end portion is attached to the support column 14 so that the upper horizontal member 62 is attached. The extension length from the column 14 is set to be shorter than the extension length from the column 14 in the intermediate horizontal member 64. Here, the arc plate 70 is attached to the distal end portion of the upper horizontal member 62, the distal end portion of the intermediate horizontal member 64, and the distal end portion of the lower horizontal member 66. For this reason, the circular arc plate 70 is stably held, and the position of the LED 18 attached to the circular arc plate 70 is also stabilized.

  Moreover, in this embodiment, the spherical part 12 shown by FIG. 1 etc. is comprised by the several piece 20 arranged in parallel around the axis line of the support | pillar 14. As shown in FIG. 2, each of the plurality of pieces 20 includes a main body portion 20 </ b> A constituting a part of the outer peripheral surface of the spherical portion 12, and another main body adjacent to the main body portion 20 </ b> A. The flange part 20B extended inside the spherical part 12 from the boundary part with the part 20A is provided. Here, since the spherical parts 12 without a welding part can be formed in an outer peripheral surface by connecting adjacent pieces 20 by the flange part 20B, the whole spherical part 12 can be made to shine with good appearance.

  As described above, according to the light emitting spherical body 10 according to the present embodiment shown in FIG. 3 and the like, it can be installed for a long period of time, and the entire spherical portion 12 can emit light even when the size is increased.

(Supplementary explanation of the embodiment)
In the above-described embodiment, the LED 18 is applied as the light source. However, the light source may be another light source such as an electroluminescent element (also referred to as electroluminescence or EL).

  Further, in the above-described embodiment, the support 14 is provided, but the light emitting spherical body may be configured without the support. That is, for example, instead of the support column 14 in the above-described embodiment, an angle material (a member constituting a part of the skeleton part) similar to the first skeleton member 42 is provided, and the spherical part is directly installed on the floor. A structure is also possible.

  Moreover, in the said embodiment, although LED18 is attached to both the 2nd frame member 52 and the circular arc board 70, it is also possible to set it as the structure where LED18 (light source) was attached only to the 2nd frame member 52, for example. In addition, it is possible to adopt a configuration in which the LED 18 (light source) is attached only to the circular arc plate 70.

  Further, as a modification of the above embodiment, there is a configuration in which the intermediate horizontal member 64 shown in FIG. 7 is not provided and the circular arc plate 70 is attached to the distal end portion of the upper horizontal member 62 and the distal end portion of the lower horizontal member 66. It can be taken.

  Further, as a modification of the above-described embodiment, a configuration in which the sub skeleton 60 including the upper horizontal member 62, the intermediate horizontal member 64, the lower horizontal member 66, and the arc plate 70 is not provided may be employed.

  Moreover, in the said embodiment, although the spherical part 12 shown by FIG. 1 is comprised by the some piece 20 arranged in parallel around the axis line of the support | pillar 14, a spherical part is a hemispherical part of the upper half, for example And the lower half of the hemispherical portion may be joined together.

  Further, the concept of “regular polygon” in “so as to form a regular polygon” according to claim 3 includes a regular polygon in a strict sense, as well as strictly as in the above embodiment. Although it is not a regular polygon, it can be grasped as a "regular polygon" with substantially the same actions and effects as the case of "forming a regular polygon in a strict sense". Such things are also included.

  In addition, the said embodiment and the above-mentioned some modification can be implemented combining suitably.

  Although an example of the present invention has been described above, the present invention is not limited to the above, and it is needless to say that various modifications can be made without departing from the spirit of the present invention. .
