In the drawings used in the following explanation, the dimensions of each component may be shown on a different scale to make them easier to see, and the dimensional ratios of each component may not necessarily be the same as in reality.

[0012] (First Embodiment) First, as a first embodiment of the present invention, we will describe, for example, the outdoor lighting device 1A shown in Figures 1 to 6.

[0013] Figure 1 is a perspective view showing the configuration of the outdoor lighting device 1A.

Figure 6 is an exploded perspective view showing the configuration of the third support column 4 on which the lighting unit 13 of the outdoor lighting device 1A is provided.

[0014] As shown in Figures 1, 2, and 3, the outdoor lighting device 1A of this embodiment comprises a first support column 2, a second support column 3, and a third support column 4. The first support column 2 is fixed in an upright position relative to a foundation (not shown), and the first support column 2, the second support column 3, and the third support column 4 are connected in series in this order, forming a long support column structure.

[0015] Furthermore, the outdoor lighting device 1A of this embodiment includes a first connecting part 5 that connects the first support column 2 and the second support column 3, a second connecting part 6 that connects the second support column 3 and the third support column 4, and a top plate part 7 attached to the upper end of the third support column 4.

[0016] The first support column 2, the second support column 3, and the third support column 4 are formed as continuous, hollow, prismatic or cylindrical (prismatic in this embodiment) members.

[0017] Furthermore, it is preferable that the second support section 3 and the third support section 4 be made of lighter material than the first support section 2. This reduces the load applied to the first support section 2 from the second support section 3 and the third support section 4, making it possible to create a structure that is less susceptible to wind.

[0018] As shown in Figure 4, the first support column 2 is made of, for example, a square steel pipe (STKR), and its lower end is fixed to the foundation by anchor bolts or the like. On the other hand, the upper end of the first support column 2 is provided with a square tube portion 2b which is fixed to the first connecting portion 5.

[0019] Furthermore, a maintenance hole 2c and a cover plate 8 that closes the maintenance hole 2c are provided on one side of the first support column 2. The cover plate 8 is attached to one side of the first support column 2 by screws or the like.

[0020] As shown in Figure 5, the second support column 3 is made of an extruded material such as an aluminum alloy, and its lower end is connected to the upper end of the first support column 2 via the first connecting portion 5 and fixed in place by screws or the like.

[0021] As shown in Figure 2, the first connecting section 5 is made of, for example, a square steel pipe (STKR), and has a structure in which a lower square tube section 5a into which the upper end (square tube section 2b) of the first support section 2 is inserted, and an upper square tube section 5b into which the lower end of the second support section 3 is inserted, are integrated by welding or the like.

[0022] As shown in Figure 6, the third support column 4 includes a rectangular frame 4a, a pair of support frames 4b attached to the upper and lower ends of the frame 4a, and a plurality (four in this embodiment) of translucent panels 4c covering the sides of the frame 4a. The frame 4a and support frames 4b are made of, for example, an aluminum alloy. The pair of support frames 4b are formed in a rectangular frame shape corresponding to the upper and lower ends of the frame 4a.

[0023] The pair of support frames 4b consist of common members that can be attached to the upper and lower ends of the frame 4a by screws or the like. In other words, these pair of support frames 4b consist of common parts with matching shapes. In this embodiment, by using common parts for these pair of support frames 4b, it is possible to reduce costs.

[0024] The light-transmitting panel 4c is made of a light-transmitting material such as a transparent resin like polycarbonate or acrylic, or glass. The light-transmitting panel 4c is formed in a rectangular flat shape corresponding to the sides of the frame 4a and is integrally attached to each side of the frame 4a by being fitted into it. Furthermore, the light-transmitting panel 4c is not limited to colorless and transparent (clear); it may also be made of a white transparent material or a material with a textured finish that has light-diffusing properties.

[0025] The third support column 4 is fixed by screws or the like, with the lower end of the frame 4a connected to the upper end of the second support column 3 via the second connecting portion 6.

[0026] As shown in Figure 2, the second connecting portion 6 is made of, for example, stainless steel, and has a structure in which a lower bottom plate portion 6a that closes the upper end of the second support portion 3 and an upper support plate portion 6b that is inserted inside the support frame 4b are integrated by fastening with screws or the like.

[0027] The top plate portion 7 is made of, for example, an aluminum alloy and forms a rectangular, flat lid. The top plate portion 7 is fixed to the upper end of the frame 4a (third support portion 4) by screws or the like, with the upper end closed.

[0028] As shown in Figure 3, the outdoor lighting device 1A of this embodiment includes a power storage unit 11 provided inside the first support column 2, a solar power generation unit 12 provided outside the second support column 3, a lighting unit 13 provided inside the third support column 4, a control unit 14 provided inside the first support column 2, a first wiring cable 15 electrically connecting the control unit 14 and the power storage unit 11, a second wiring cable 16 electrically connecting the control unit 14 and the solar power generation unit 12, and a third wiring cable 17 electrically connecting the control unit 14 and the lighting unit 13.

[0029] As shown in Figures 2 and 4, the energy storage unit 11 has a storage battery 11a, such as a lithium-ion battery. The storage battery 11a is housed inside the first support column 2.

[0030] Furthermore, there are no particular limitations on the type of lithium-ion battery used as the storage battery 11a; conventionally known types can be used. In addition, batteries other than lithium-ion batteries, such as lead-acid batteries, may be used as the storage battery 11a.

[0031] As shown in Figures 2 and 5, the solar power generation unit 12 has a plurality of (four in this embodiment) solar panels 12a. The solar panels 12a are formed in a rectangular flat shape corresponding to the side surface of the second support column 3 and are integrally attached to each side surface of the second support column 3.

[0032] The second support column 3 is provided with a guide groove 3a for attaching the solar panel 12a. The guide groove 3a is provided extending vertically along the corner of the second support column 3.

[0033] The solar panel 12a is attached to the side of the second support column 3 with both of its side ends inserted into the guide grooves 3a.

[0034] As shown in Figures 2 and 6, the lighting unit 13 includes a luminaire 13a and a cylindrical light-diffusing cover 13b that surrounds the luminaire 13a.

[0035] The lighting fixture 13a is a light-emitting module that uses multiple light sources 31, such as light-emitting diodes (LEDs), and has a structure in which multiple light sources 31 are mounted in a vertical and circumferential direction on the outer surface of a support shaft 32 that extends in the vertical direction.

[0036] The lighting fixture 13a is located in the inner center of the frame 4a (third support column 4), and is positioned in the inner center of the third support column 4 by fixing both ends of the support shaft 32 to the second connecting part 6 and the top plate part 7.

[0037] As a result, the lighting fixture 13a emits light radially from the center of the third support column 4 toward the outer periphery, making it possible to emit light over the entire circumference and length of the third support column 4.

[0038] The lighting fixture 13a is not necessarily limited to the light-emitting module described above, but may also use fluorescent lamps, incandescent lamps, etc.

[0039] The light diffusion cover 13b is made of a light-transmitting material such as a transparent resin like polycarbonate or acrylic, or glass. Furthermore, to diffuse the light emitted from the illuminator 13a, the light diffusion cover 13b may be made of a white, transparent material or one with a textured finish.

[0040] The light-diffusing cover 13b is positioned inside the frame 4a (third support column 4) so ​​as to surround the luminaire 13a and is held between the second connecting portion 6 and the top plate portion 7.

[0041] As shown in Figures 2, 3, and 4, the control unit 14 has a control circuit board 14a that controls each part and is housed inside the first support column 2.

[0042] The first connecting portion 5 is provided with a first opening 5c ​​through which the second wiring cable 16 and the third wiring cable 17 pass. In this embodiment, the first opening 5c ​​is an opening that extends along the entire length of the inside of the lower and upper rectangular tube portions 5a and 5b.

[0043] The second connecting portion 6 is provided with a second opening 6c through which the third wiring cable 17 passes. In this embodiment, the second opening 6c is a hole that opens in the center of the bottom plate portion 6a and the support plate portion 6b.

[0044] In the outdoor lighting device 1A of this embodiment, which has the above configuration, the control unit 14 detects the electromotive force (voltage) of the solar panel 12a to determine whether it is daytime or nighttime.

[0045] During the daytime, the control unit 14 controls the charging of the battery 11a (energy storage unit 11) with electricity generated by the solar panel 12a (solar power generation unit 12). At this time, the control unit 14 also controls the power supply from the battery 11a to the lighting fixture 13a (lighting unit 13). As a result, the lighting fixture 13a (lighting unit 13) is turned off.

[0046] Meanwhile, the control unit 14 controls the supply of power from the battery 11a to the lighting fixture 13a (lighting unit 13) during nighttime hours. As a result, the lighting fixture 13a (lighting unit 13) remains lit (ON).

[0047] As described above, the outdoor lighting device 1A of this embodiment can automatically control the lighting (ON / OFF) of the lighting fixture 13a without receiving power from an external power source.

[0048] In this embodiment, the outdoor lighting device 1A has a support structure that is divided into a first support section 2 on which the aforementioned energy storage unit 11 and control unit 14 are provided, a second support section 3 on which the solar power generation unit 12 is provided, and a third support section 4 on which the lighting unit 13 is provided. This makes it possible to improve the assembly workability of the outdoor lighting device 1A in this embodiment.

[0049] Furthermore, in the outdoor lighting device 1A of this embodiment, the first support column 2, the second support column 3, and the third support column 4 described above have a hollow structure, and the third wiring cable 17 can be passed through the second opening 6c provided in the second connecting portion 6, and the second wiring cable 16 and the third wiring cable 17 can be passed through the first opening 5c ​​provided in the first connecting portion 5. As a result, wiring work can be simplified in the outdoor lighting device 1A of this embodiment.

[0050] As described above, the outdoor lighting device 1A of this embodiment offers excellent assembly workability and simplifies wiring work.

[0051] (Second embodiment) Next, as a second embodiment of the present invention, an outdoor lighting device 1B shown in Figures 7 to 11 will be described.

[0052] Figure 7 is a perspective view showing the configuration of the outdoor lighting device 1B. Figure 8 is an exploded perspective view showing the configuration of the outdoor lighting device 1B. Figure 9 is a schematic diagram showing the configuration of the outdoor lighting device 1B. Figure 10 is an exploded perspective view showing the configuration of the first support column 21 on which the energy storage unit 11, solar power generation unit 12, and control unit 14 of the outdoor lighting device 1B are provided. Figure 11 is an exploded perspective view showing the configuration of the second support column 22 on which the lighting unit 13 of the outdoor lighting device 1B is provided. Furthermore, in the following description, parts equivalent to those of the outdoor lighting device 1A will not be described and will be denoted by the same reference numerals in the drawings.

[0053] As shown in Figures 7, 8, and 9, the outdoor lighting device 1B of this embodiment comprises a first support column 21 and a second support column 22, the first support column 21 being fixed in an upright position relative to a foundation (not shown), and the first support column 21 and the second support column 22 having a support column structure connected in series.

[0054] Furthermore, the outdoor lighting device 1B of this embodiment includes a connecting portion 23 that connects the first support portion 21 and the second support portion 22, and a top plate portion 24 attached to the upper end of the second support portion 22.

[0055] The first support column 21 and the second support column 22 are formed as continuous, hollow prismatic or cylindrical (prismatic in this embodiment) members.

[0056] Furthermore, it is preferable that the second support column 22 be made of a lighter material than the first support column 21. This reduces the load applied from the second support column 22 to the first support column 21, making it possible to create a structure that is less susceptible to wind.

[0057] The first support column 21 has basically the same configuration as the first support column 2, as shown in Figure 10. The second support column 22 has basically the same configuration as the third support column 4, as shown in Figure 11, except that its overall length is shorter (lower). The connecting portion 23 has basically the same configuration as the second connecting portion 6, as shown in Figure 8. The top plate portion 24 has basically the same configuration as the top plate portion 7, as shown in Figure 8.

[0059] As shown in Figures 7 and 8, the solar panel 12a is formed in a rectangular flat shape corresponding to the side surface of the first support column 21 and is integrally attached to the remaining side surface of the first support column 21, excluding the side surface where the maintenance hole 2c is provided.

[0060] In the outdoor lighting device 1B of this embodiment, which has the above configuration, the control unit 14 detects the electromotive force (voltage) of the solar panel 12a to determine whether it is daytime or nighttime.

[0061] During the daytime, the control unit 14 controls the charging of the battery 11a (energy storage unit 11) with electricity generated by the solar panel 12a (solar power generation unit 12). At this time, the control unit 14 also controls the power supply from the battery 11a to the lighting fixture 13a (lighting unit 13). As a result, the lighting fixture 13a (lighting unit 13) is turned off.

[0062] Meanwhile, the control unit 14 controls the supply of power from the battery 11a to the lighting fixture 13a (lighting unit 13) during nighttime hours. As a result, the lighting fixture 13a (lighting unit 13) remains lit (ON).

[0063] As described above, the outdoor lighting device 1B of this embodiment can automatically control the lighting (ON / OFF) of the lighting fixture 13a without receiving power from an external power source.

[0064] In the outdoor lighting device 1B of this embodiment, the support structure is divided into a first support section 21 on which the aforementioned energy storage unit 11, solar power generation unit 12, and control unit 14 are provided, and a second support section 22 on which the lighting unit 13 is provided. This makes it possible to improve the assembly workability of the outdoor lighting device 1B of this embodiment.

[0065] Furthermore, in the outdoor lighting device 1B of this embodiment, the first support column 21 and the second support column 22 described above have a hollow structure, and the third wiring cable 17 can be passed through the opening 6c provided in the connecting portion 23. As a result, wiring work can be simplified in the outdoor lighting device 1B of this embodiment.

[0066] As described above, the outdoor lighting device 1B of this embodiment offers excellent assembly workability and simplifies wiring work.

[0071] The first support column 41, the second support column 42, and the third support column 43 are formed as continuous, hollow, prismatic or cylindrical (prismatic in this embodiment) members.

[0072] Furthermore, it is preferable that the third support column 43 be made of a member that is lighter and shorter in overall length than the second support column 42. This reduces the load applied from the third support column 43 to the second support column 42, making it possible to create a structure that is less susceptible to wind.

[0084] Furthermore, there are no particular limitations on the type of lithium-ion battery used as the storage battery 51a; conventionally known types can be used. In addition, batteries other than lithium-ion batteries, such as lead-acid batteries, may be used as the storage battery 51a.

[0085] The solar power generation unit 53 has a plurality of (four in this embodiment) solar panels 53a. The solar panels 53a are formed in a rectangular flat shape corresponding to the side surface of the second support column 42 and are integrally attached to each side surface of the second support column 42.

[0086] The second support column 42 is provided with a guide groove 42a for attaching the solar panel 53a. The guide groove 42a is provided extending vertically along the corner of the second support column 42.

[0087] The solar panel 53a is attached to the side of the second support column 42 with both of its side ends inserted into the guide grooves 42a.

[0088] The lighting unit 54 has a lighting fixture 54a. The lighting fixture 54a is a light-emitting module that uses multiple light sources 61, such as light-emitting diodes (LEDs), and has a structure in which multiple light sources 31 are mounted in a vertical and circumferential direction on the outer surface of a hollow support shaft 62 that extends in the vertical direction. The lighting fixture 54a also has elongated plate-shaped fixing parts 63 that extend in all four directions from the upper end of the support shaft 62.

[0089] The lighting fixture 54a is suspended from the top plate portion 46, and is positioned in the inner center of the light diffusion cover 43a (third support column portion 43) by fixing the fixing portion 63 to the underside of the top plate portion 46 with screws or the like.

[0090] As a result, the lighting fixture 54a emits light radially from the center of the light diffusion cover 43a (third support column 43) toward the outer periphery, making it possible to emit light over the entire circumference of the third support column 43.

[0091] The lighting fixture 54a is not necessarily limited to the light-emitting module described above, but may also use fluorescent lamps, incandescent lamps, etc.

[0092] The control unit 52 has a control circuit board 52a that controls each part and is housed inside the second support column 42.

[0093] The second connecting portion 45 is provided with an opening 45c through which the third wiring cable 57 passes. In this embodiment, the opening 45c is a hole that is opened in the center of the upper plate portion 45a and the bottom plate portion 45b.

[0094] In the outdoor lighting device 1C of this embodiment, which has the above configuration, the control unit 52 detects the electromotive force (voltage) of the solar panel 53a to determine whether it is daytime or nighttime.

[0095] During the daytime, the control unit 52 controls the charging of the battery 51a (energy storage unit 51) with electricity generated by the solar panel 53a (solar power generation unit 53). At this time, the control unit 52 also controls the power supply from the battery 51a to the lighting fixture 54a (lighting unit 54). As a result, the lighting fixture 54a (lighting unit 54) is turned off.

[0096] Meanwhile, the control unit 52 controls the supply of power from the battery 51a to the lighting fixture 54a (lighting unit 54) during nighttime hours. As a result, the lighting fixture 54a (lighting unit 54) remains lit (ON).

[0097] As described above, the outdoor lighting device 1C of this embodiment can automatically control the lighting (ON / OFF) of the lighting fixture 54a without receiving power from an external power source.

[0098] The outdoor lighting device 1C of this embodiment has a support column structure that is divided into the first support column 41 described above, the second support column 42 on which the energy storage unit 51, control unit 52 and solar power generation unit 53 are provided, and the third support column 43 on which the lighting unit 54 is provided. As a result, the outdoor lighting device 1C of this embodiment can be assembled more easily.

[0099] Furthermore, in the outdoor lighting device 1C of this embodiment, the second support column 42 and the third support column 43 described above have a hollow structure, and the third wiring cable 57 can be passed through the opening 45c provided in the second connecting portion 45. As a result, wiring work can be simplified in the outdoor lighting device 1C of this embodiment.

[0100] As described above, the outdoor lighting device 1C of this embodiment offers excellent assembly workability and simplifies wiring work.

[0101] It should be noted that the present invention is not necessarily limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. For example, the outdoor lighting device to which the present invention is applied is not necessarily limited to the configuration of the outdoor lighting devices 1A and 1B described above, and can be implemented by appropriately changing the shape of each support column and the design of the lighting unit.
