Is expressed as the inner peripheral side or the center side, and the outer peripheral side of the central axis L1 is expressed as the outer peripheral side.

(Lighting device body)
2A and 2B are views showing the lighting device body 20, FIG. 2A is a view of the lighting device body 20 viewed from the side, and FIG. 2B is a view of the lighting device body 20 viewed from below. FIG. 3 is an exploded perspective view of the lighting device body 20.
The illuminating device main body 20 includes a cap portion 21 that covers the top surface of the pole 11, a plurality of (two in this embodiment) support posts 12 that are attached to the top surface of the cap portion 21, and a top surface portion 13 that is attached to the top surface of the support post 12. And. An illumination unit 30 is provided for each of the columns 12.

  The cap portion 21 has a cylindrical insertion portion 21A that can be inserted into the upper opening of the pole 11, and a circular bowl-shaped upper plate portion 21B that closes the upper opening of the insertion portion 21A and projects outward in the radial direction of the insertion portion 21A. And integrated. With this configuration, when the insertion portion 21A is inserted into the pole 11, the peripheral portion of the upper plate portion 21B comes into contact with the upper surface of the pole 11, and further insertion is restricted. In this case, the insertion portion 21 </ b> A is fitted to the pole 11, and the cap portion 21 does not move in the circumferential direction of the pole 11. As a result, the cap portion 21 can be positioned on the pole 11.

As shown in FIG. 3, the upper plate portion 21B constituting the upper surface of the cap portion 21 is formed with a concave portion 21C that is recessed downward with an interval in the circumferential direction (an interval of 180 degrees in the present embodiment). As shown in FIG. 1, each of the support 12 and the globe 32 included in the illumination unit 30 is inserted and placed in each recess 21 </ b> C. That is, each recess 21 </ b> C constitutes the seating surface of each support column 12 and the seating surface of the illumination unit 30 (glove 32).
A region of the upper surface of the upper plate portion 21B excluding the concave portion 21C is a curved surface having a curved shape that is highest at the center of the cap portion 21 and gradually decreases toward the outer periphery of the cap portion 21 as shown in FIG. Part 21D is formed. For this reason, rain water etc. can be dropped to the circumference along the curved surface portion 21D, rain water can be prevented from accumulating on the upper surface of the cap portion 21, and even if dust adheres, it can be washed away with rain water.

As shown in FIG. 3, the support column 12 is smaller than the pole 11 and is formed in a hollow column shape extending in the vertical direction. The column 12 is placed in the recess 21C, and a plurality of (two) fastening members 41 are fastened to a female screw (not shown) provided at the lower end of the column 12 from below the cap unit 21 so that the column 12 is capped.

And a pair of left and right plate portions PC (hereinafter referred to as “side plate portions PC”) that connect between the side edges of the central side plate portion PA and the outer side plate portion PB. The part PA is formed in a trapezoidal cross section that is narrower than the outer plate part PB.

FIG. 4 is a view showing the concave portion 21 </ b> C of the cap portion 21 together with the peripheral configuration. FIG. 5 is a view showing a part of the XX cross section of FIG.
As shown in FIG. 4, a first positioning member 21 </ b> E for positioning the column 12 and a second positioning member 21 </ b> F are integrally provided in the recess 21 </ b> C of the cap portion 21.
As shown in FIG. 4, the first positioning member 21 </ b> E is formed on a rib that is substantially along the radial direction of the cap portion 21 and protrudes upward. As shown in FIG. 5, the support 12 is fixed to the recess 21 </ b> C. When it is arranged at the power position, it comes into contact with the inner surface on one side of the pair of left and right side plate portions PC of the column 12. Thereby, the side board part PC of the support | pillar 12 is positioned.

Further, the second positioning member 21F is formed on a rib projecting upward substantially along the circumferential direction of the cap portion 21 on the radially outer side of the cap portion 21 with respect to the first positioning member 21E. As shown in FIG. 2, when the support column 12 is disposed at a position where the recess 21C is to be fixed, the support 12 abuts against the inner surface of the outer plate portion PB of the support column 12. Thereby, the outer side plate part PB of the support | pillar 12 is positioned.
By positioning the column 12 by the first positioning member 21E and the second positioning member 21F, the movement of the column 12 in the radial direction and the circumferential direction can be restricted. Further, even if the orientation of the support column 12 is wrongly assembled, at least one of the first positioning member 21E and the second positioning member 21F comes into contact with the lower end of the support column 12, so that the support column 12 cannot be assembled. , Can avoid mistakes. As described above, variations in the position and orientation of the support column 12 can be suppressed.

More specifically, the first positioning member 21E not only contacts the side plate portion PC of the support column 12, but also has one end portion in the longitudinal direction (end on the radially inner side of the cap portion 21) as shown in FIG. Is equivalent to the inner surface of the center side plate portion PA of the column 12. That is, the first positioning member 21E comes into contact with the two surfaces of the side plate portion PC and the center side plate portion PA of the support column 12. This restricts the movement of the support column 12 outward in the radial direction and the movement in the circumferential direction.
Further, as shown in FIG. 5, the second positioning member 21 </ b> F is not only in contact with the outer side plate portion PB of the support column 12, but as shown in FIG. Abut against the inner surfaces of the pair of side plate portions PC. That is, the second positioning member 21F abuts against the three surfaces of the outer plate portion PB of the support column 12 and the left and right side plate portions PC. Thereby, the movement of the support column 12 in the radial direction and the movement in the circumferential direction are restricted.
By these, the movement to the radial direction of the support | pillar 12 and the circumferential direction can be controlled effectively, and an assembly mistake can be prevented effectively.

As shown in FIG. 4, a pair of holes 21H and a wiring hole 21J are formed between the first positioning member 21E and the second positioning member 21F. The pair of holes 21H are through-holes through which the pair of fastening members 41 for fastening the support column 12 pass, and the wiring hole 21J is a through-hole through which the wiring 30A (FIG. 3) extending from the illumination unit 30 passes. .
In addition, a pair of through holes 21K penetrating vertically through the recess 21C is also formed between the peripheral wall 21W constituting the peripheral edge of the recess 21C and the hole 21H and the wiring through hole 21J. These through-holes 21K are drain holes for discharging rainwater into the concave portion 21C before the wiring holes 21J.

  Further, the concave portion 21 </ b> C is formed in a concave shape that is recessed along the outer shape of the globe 32 included in the illumination unit 30. Thereby, the surrounding wall 21W of the recess 21C serves as a guide when assembling the globe 32, and it is possible to prevent misassembly of the globe 32 and to suppress variations in the position and orientation of the globe 32.

As shown in FIG. 1, the top surface portion 13 is placed on the upper end of the support column 12 so as to straddle a plurality of (two) support columns 12, and is attached to a female screw (not shown) provided on the upper end of the support column 12. The top surface portion 13 is fixed to the column 12 by fastening the fastening member 43 (FIGS. 1 and 3) via the surface portion 13. The top surface portion 13 is formed in a hollow box shape having substantially the same diameter as that of the cap portion 21, and as shown in FIG. 3, the top surface portion main body 13A having a closed top surface and opened downward, A decorative plate 13B that is connected to the lower side of the surface portion main body 13A and forms the lower surface of the top surface portion 13 is provided.
As shown in FIG. 3, a glove 32 included in the illumination unit 30 is inserted between the top surface portion 13 and the cap portion 21, and this glove 32 is vertically moved via a glove packing 33 (FIG. 3). The top surface portion 13 and the cap portion 21 are connected. The glove packing 33 can effectively suppress the intrusion of rainwater or outside air into the glove 32 from the outside, and can be waterproof and moisture-proof.

(Lighting unit)
The illumination unit 30 is provided for each column 12, and each illumination unit 30 has the same structure. As shown in FIG. 3, the illumination unit 30 includes a rectangular rod-shaped light source unit 31 attached to the center side plate portion PA of the support column 12 and a globe 32 that covers each light source unit 31.
6A and 6B are diagrams showing the light source unit 31, FIG. 6A is a side view of the light source unit 31, FIG. 6B is a plan view, and FIG. 6C is YY in FIG. 6B. It is sectional drawing.
The light source unit 31 is formed in a rectangular bar shape that extends in a direction that coincides with the longitudinal direction of the support column 12, and is an LED unit that uses an LED (Light Emitting Diode) as a light source. The light source unit 31 includes a substrate 35 on which LEDs are arranged at intervals in the longitudinal direction of the light source unit 31, a rectangular cylindrical unit case 36 that accommodates the substrate 35, and openings that are open at both ends of the unit case 36. A pair of upper and lower waterproof bushings 37 (attachment parts) for closing the portion 36A (FIG. 6C) are provided.

The waterproof bushing 37 is formed of an elastic material such as rubber, and closes the opening portion 36A by fitting into the opening portion 36A of the unit case 36, thereby preventing water and the like from entering from the outside to achieve waterproofing and moisture prevention. It is a part.
Further, the unit case 36 itself is formed in a case where water or the like does not enter from outside the opening 36A of the unit case 36, that is, the unit case 36 itself. Therefore, the unit case 36 and the waterproof bushing 37 form the light source unit 31 in a waterproof and moisture-proof structure in which water or the like does not enter from the outside.
Note that the wiring 30 </ b> A extending from the substrate 35 is pulled out of the light source unit 31 through a hole 37 </ b> A (FIG. 7A described later) provided in the waterproof bushing 37. At this time, the clearance between the wiring 30A and the waterproof bushing 37 is closed by the elasticity of the waterproof bushing 37, and water or the like does not enter inside.

The globe 32 is a cover component that covers the light source unit 31 attached to the column 12. As shown in FIG. 3, the globe 32 is formed in a cover shape having a substantially trapezoidal cross section in which a part of the outer peripheral side is opened up and down, and both side edges forming the opening are formed on the left and right of the support column 12. By engaging with the provided groove portion 12M (FIG. 5), the left and right side plate portions PC of the support column 12 are covered with a gap therebetween so as to straddle the light source unit 31.
Accordingly, as shown in FIG. 5, the glove 32 includes an inner glove 32 </ b> M that surrounds the inner peripheral side (center side plate portion PA, side plate portion PC) of the support 12 in a fan shape, and the outer plate of the support 12. It has the outer peripheral side globe 32N which continues to the left and right of the PB.
The globe 32 is made of frosted glass or milky white resin material as an example of a light diffusing cover. When the light source unit 31 is turned on, the entire surface of the globe 32 (inner circumferential side globe 32M, outer circumferential side globe 32N) becomes bright. The illumination light can be irradiated toward the inner peripheral side and the outer peripheral side of the support column 12.

(Waterproof bushing)
7 is a view showing the waterproof bushing 37, FIG. 7A is a plan view of the waterproof bushing 37, FIG. 7B is a view as seen from the lower side of FIG. 7A, and FIG. It is the figure seen from the side of Drawing 7 (A).
The waterproof bushing 37 includes an insertion portion 50 that is inserted into the opening 36A (FIG. 6C) of the unit case 36 of the light source unit 31, and an external exposure portion 51 that is provided at the base end of the insertion portion 50 and is exposed to the outside. And integrated.
The insertion portion 50 has a configuration in which a plurality of flange portions are provided around the shaft portion that can be inserted into the opening portion 36A of the unit case 36 with an interval in the axial direction. When the insertion portion 50 is inserted into the opening portion 36A, The gap between the shaft portion and the opening portion 36A is closed with the flange portion.

  The externally exposed portion 51 is formed larger than the opening portion 36A of the unit case 36. When the insertion portion 50 is inserted into the opening portion 36A, the external exposed portion 51 abuts against the end portion of the unit case 36 and further insertion is performed. regulate. The externally exposed portion 51 includes an externally exposed portion main body 52 formed in the same rectangular outer shape as the end portion of the unit case 36, a first protrusion 52A that protrudes relatively large from the externally exposed portion main body 52, an external portion The second protrusion 52B protrudes from the exposed portion main body 52 to be smaller than the first protrusion 52A.

The first protrusion 52A is a protrusion whose distal end 52C extends radially outward from the base end 52D, and is inserted into a hole 12X (FIG. 3) provided in the support column 12. The distal end portion 52C is formed in a tapered shape that gradually tapers toward the distal end, making it easy to insert the distal end portion 52C into the hole portion 12X, and making the back surface of the distal end portion 52C the back side of the hole portion 12X ( It is easy to lock to the back side.
FIG. 8 is a view showing the externally exposed portion 51 together with the hole 12X of the support column 12. FIG. 8A shows a state before the first protrusion 52A of the externally exposed portion 51 is inserted, and FIG. Indicates the middle of insertion, and FIG. 8C shows the state after insertion.
As shown in FIG. 8A, the distal end 52C of the first protrusion 52A has a leading edge outer diameter d1 smaller than the inner diameter d0 of the hole 12X, and the outer diameter d2 of the rearmost end is an inner diameter of the hole 12X. It is formed larger than d0 (value d1 <value d0 <value d2). Further, the outer shape d3 of the base end portion 52D of the first projecting portion 52A is formed to be smaller than the inner diameter d0 of the hole portion 12X (value d3 <value d0).
Therefore, the tip 52C can be easily inserted into the hole 12X of the support column 12, and the tip 52C of the first protrusion 52A passes through the hole 12X of the support column 12 as shown in FIG. 8C. The tip 52C of the first protrusion 52A can be reliably locked to the back side (back surface) of the hole 12X.

  The second protrusion 52B is formed as a protrusion that comes into contact with the front side of the hole 12X (corresponding to the surface around the hole 12X) when the tip 52C of the first protrusion 52A passes through the hole 12X. Yes. As shown in FIG. 8 (A), the protrusion amount of the second protrusion 52B is a distance t1 between the tip of the second protrusion 52B and the rear end 52C of the first protrusion 52A. The protruding amount is shorter than the length t0 of the portion 12X (corresponding to the thickness of the center side plate portion PA of the support column 12) (value t1 <value t0). Further, the separation distance t2 (corresponding to the length of the base end portion 52D) (FIG. 8A) to the distal end portion 52C of the first protrusion 52A is longer than the length t0 of the hole 12X (value t2>). Value t0).

  Therefore, by passing the first protrusion 52A through the hole 12X, as shown in FIG. 8B, the second protrusion 52B is placed on the front side of the hole 12X (corresponding to the surface around the hole 12X). It can be made to contact. In this state, since the separation distance t1 is shorter than the length t1 of the hole 12X, the tip 52C of the first protrusion 52A does not penetrate the hole 12A.

In order for the tip 52C of the first protrusion 52A to penetrate the hole 12X, the external exposed part 51 is pushed toward the hole 12X, and the external exposed part 51 is elastically deformed as shown in FIG. 8C. Thereby, the first protrusion 52A further enters the hole 52A, the tip 52C penetrates the hole 52A, and the back surface of the tip 52C is locked to the back side of the hole 12X.
In this case, as shown in FIG. 8C, the externally exposed portion 51 is locked in a state of being elastically deformed. For this reason, the restoring force that the externally exposed portion 51 tries to return to the original shape is generated, and by this restoring force, the first projecting portion 52A and the second projecting portion 52B of the support column 12 that is a member having the hole portion 12X. The force which clamps a board part (center side board part PA) acts. Thereby, compared with the state shown in FIG. 8B, the connecting force between the waterproof bushing 37 and the column 12 is improved, and the waterproof bushing 37 and the column 12 can be connected with a strong connecting force.

  In this way, since the connecting force between the waterproof bushing 37 and the support column 12 is improved, the supporting force of the light source unit 31 to which the waterproof bushing 37 is attached can be improved. The unit 31 can be supported on the column 12. Therefore, compared with the case where the light source unit 31 is fixed to the support | pillar 12 using the conventional screw, the number of parts can be reduced and the support structure of the light source unit 31 can be simplified.

In addition, it is possible to adjust the supporting force of the light source unit 31 by adjusting both or one of the value t2 and the value t1.
As a result of studies by the inventors, it was preferable to set the value t2 to a value (t0 + 1) mm or more. That is, a sufficient supporting force could be obtained by securing the deformation amount of the external exposed portion 51 of 1 mm or more. As described above, in the present embodiment, the waterproof bushing 37 allows the light source unit 31 to have a waterproof and moisture-proof structure and allows the light source unit 31 to be easily supported by the support column 12.

The wiring 30 </ b> A extending from the substrate 35 of the light source unit 31 passes through the hole 12 </ b> Y (FIG. 3) provided in the center side plate portion PA of the column 12, passes through the column 12, and is provided in the recess 21 </ b> C of the cap unit 21. It is drawn into the cap portion 21 through the wiring hole portion 21J (FIG. 4).
In this case, since the wiring 30A passes through the region surrounded by the column 12 and the globe 32 and the column 12, the wiring 30A can be waterproofed and moisture-proof from rain water or the like without providing a special waterproof and moisture-proof component. A waterproof connector 30B (FIG. 3) is provided at the tip of the wiring 30A, and the wiring 30A is connected to the power supply unit 60 provided on the back surface of the cap portion 21 via the waterproof connector 30B. By using the waterproof connector 30B, the wiring connection part between the light source unit 31 and the power supply unit 60 can be easily waterproofed and moisture-proof.

(Power supply unit)
The power supply unit 60 controls the lighting of the light source unit 31 by supplying power to the light source unit 31 via the wiring 30A.
9 is a view showing the power supply unit 60 together with the cap portion 21, FIG. 9A is a view of the power supply unit 60 seen from below with the cap portion 21, and FIG. 9B is a view of Z in FIG. 9A. It is the figure which showed the -Z cross section. In FIG. 9A, the fastening member 41 for attaching the support column 12 to the cap portion 21 is omitted. FIG. 10 is an exploded perspective view of the power supply unit 60 and the cap portion 21.
The power supply unit 60 is fixed to the back surface of the upper plate portion 21 </ b> B of the cap portion 21, and the periphery thereof is covered with the cylindrical insertion portion 21 </ b> A of the cap portion 21. As shown in FIG. 10, the power supply unit 60 has an insulating sheet 62 and a power supply attachment plate 63 attached to a substrate 61 constituting a power supply circuit, and is fastened and fixed to the upper plate portion 21 </ b> B of the cap portion 21 by a fastening member 45. .

As shown in FIG. 10, a cylindrical partition plate 65 that extends downward from the power supply unit 60 in a rectangular cross section that surrounds the power supply unit 60 is integrally provided on the upper plate portion 21 </ b> B of the cap portion 21. The partition plate 65 prevents rainwater and the like from entering from the side of the power supply unit 60, and can be waterproof and moisture-proof.
Further, as shown in FIG. 4, a plurality of holes 21H, 21J, and 21K are formed in the upper plate portion 21B as through holes that penetrate the upper plate portion 21B. 21J and 21K are formed between the partition plate 65 and the insertion portion 21A of the cap portion 21 as shown in FIG. 9A.
