Summary of the Invention

Problems to be Solved by the Invention

[0004] In the exterior lighting device described in Patent Document 1, it is a plug-in type lighting device that inserts the spike portion into the ground, and as described above, the left-right orientation of the lamp unit can be changed by reinserting the spike portion into the ground. Therefore, the exterior lighting device itself does not have a configuration that allows the lamp unit to rotate left and right. Incidentally, there are cases where it is desirable to attach the lighting fixture using mounting hardware that can be installed on the walls or columns of outdoor structures, for example. In such cases, it is desirable for the outdoor lighting device itself to be configured so that the light fixture can rotate left and right. However, if the outdoor lighting device is modified to allow for further left and right rotation, and a new rotating part is added, the lighting device may become larger due to the need to include a configuration for connecting wiring inside the fitting and fixing part, or the addition of a new rotating part, and there is also a risk of interference between the newly constructed rotating part and the wiring.

[0005] The object of the present invention is to provide a lighting device that can suppress an increase in size and suppress interference between the rotating part and the wiring. [Means for solving the problem]

[0006] The lighting device of the present invention comprises a lamp unit through which wiring is brought out to the outside, a base unit connected to the lamp unit, and a case body having a concave base unit that is rotatably positioned on the base unit and having the wiring arranged inside, wherein the base unit and the base unit unit constitute a rotating part that makes the lamp unit rotatable, and the case body has an entry-side wiring groove through which the wiring being pulled into the inside of the case body is inserted, an exit-side wiring groove through which the wiring being pulled out from the inside of the case body is inserted, and in the direction in which the wiring is inserted into the case body The rotating portion is provided with a mounting portion that is positioned on the input side wiring groove and to which a swing restricting device is attached to restrict the swinging of the wiring, and a mounting projection that is positioned on the output side wiring groove relative to the rotating portion in the insertion direction and to which a wiring fastener is attached to fix the wiring, and the restricted position of the wiring whose swinging is restricted by the swing restricting device and the fixed position of the wiring whose fixing is fixed by the wiring fastener are positioned on the opposite side of the rotating portion from the base portion in the front-rear direction perpendicular to the insertion direction. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a lighting device that can suppress an increase in size and suppress interference between the rotating part and the wiring. [Brief explanation of the drawing]

[0009] [Structure of this embodiment] Embodiments of the present invention will be described below with reference to the drawings. In Figures 1 and 2, the lighting device 1 according to this embodiment is a wall-mounted exterior lighting device fixed to walls, columns, etc., around a building. This lighting device 1 comprises a lamp unit 21 from which wiring 2 is brought out to the outside, a die-cast base unit 31 with a connecting part 25 formed thereon that connects the lamp unit 21 so as to be able to rotate up and down about a rotation axis O1 along the X-axis, a die-cast case body 61 having a concave base mounting part 65 that is arranged so as to be able to rotate left and right about a rotation axis O2 (see Figure 4) along the Z-axis, and in which wiring 2 is arranged, a base body 71 to which the case body 61 is attached, a swing restrictor 91 which is a metal fitting that restricts the swinging of wiring 2 inside the case body 61, and a tension stopper 95 which is a metal fitting that acts as a wiring stopper to fix wiring 2 inside the case body 61. The base portion 31, which includes the light unit 21 and the connecting portion 25, constitutes the lighting body 20, while the case body 61, base body 71, swing restrictor 91, and tension stopper 95 constitute the installation device 60 to which the lighting body 20 is attached. In the following description, the left-right direction (width direction) of the lighting device 1 is defined as the X-axis direction, the up-down direction of the lighting device 1 is defined as the Y-axis direction, and the front-back direction of the lighting device 1 is defined as the Z-axis direction. The X, Y, and Z axis directions are orthogonal to each other.

[0010] The light unit 21 has a light source (not shown) such as an LED that emits light from the front of the main body 22, and wiring 2 is routed to the outside from the back of the main body 22. The light unit 21 is waterproofed on its own, so there is no need to waterproof the connecting part 25, the base part 31, and the mounting equipment 60. Furthermore, as shown in Figures 7(A) to (C), the light unit 21 has a main body 22 having a front portion 221 and a rear portion 222, and the aforementioned bearing portion 23 which is attached to the main body 22 and connected to the base portion 31 so as to be vertically rotatable, and the bearing portion 23 is connected to the connecting portion 25. The rear portion 222 has a rear cylindrical portion 224 having a notch 223 in which the bearing portion 23 is arranged, and a rear bottom portion 225 that closes the rear cylindrical portion 224 on the front portion 221 side and through which the wiring 2 is pulled out. The rear bottom portion 225 has a water reservoir portion 226 on its bottom surface that is closer to the front portion 221 side. The bottom surface 230 of the notch 223 is positioned flush with the bottom surface 231 of the water reservoir portion 226, allowing rainwater and the like to be smoothly drained from the notch 223. In this embodiment, the bearing portion 23 has a recess 232 formed in it at a position opposite the bottom surface 230 of the notch 223 to improve drainage, but the recess 232 may be omitted if sufficient drainage can be ensured.

[0011] The base portion 31 has an outer circular base body portion 32 and a substantially cylindrical inner cylindrical portion 33 that protrudes downward from the center of the base body portion 32. As shown in Figures 3 and 4, the base body 32 has a disc-shaped top plate 321 and a cylindrical outer cylindrical portion 322 extending downward from the periphery of the top plate 321. The outer circumference of the outer cylindrical portion 322 is circular and slightly inclined so as it goes downward, it approaches the inner cylindrical portion 33. The top plate 321 has a bearing portion 26 (see Figure 4) formed on which the aforementioned connecting portion 25 extends upward, and it connects with the bearing portion 23 of the light unit 21 to form a hinge mechanism. The rotational axis O1 of the bearing sections 23 and 26 is aligned with the X-axis direction, and therefore the light unit 21 can rotate up and down (oscillate) around the rotational axis O1 relative to the connecting section 25. The vertical direction of the light emitted by the light unit 21 is adjusted by this vertical rotation. The inner cylindrical portion 33 protrudes downward from the center of the top plate 321, and its lower edge of its outer peripheral edge 332 is positioned so that it is flush with the lower edge of the outer cylindrical portion 322. The inner cylindrical portion 33 has an outer circular central projection 331 that protrudes further downward from its central portion. This central projection 331 is cylindrical and protrudes lower than the outer cylindrical portion 322. An annular groove 333 is formed between the central projection 331 and the outer peripheral edge 332, in which an O-ring 113, which will be described later, can be placed. Furthermore, on the lower surface 34 of the central projection 331 of the base portion 31, there is a mounting portion 35 to which a retaining member 100 can be attached to prevent it from coming off the base positioning portion 65 of the base portion 31, and two positioning protrusions 37 that position and guide the retaining member 100 to a predetermined position when it is away from the wiring 2. Here, the retaining member 100 is a metal fitting having a disc-shaped body 101 with a larger diameter than the central projection 331, and a restricted portion 102 that protrudes radially from the disc-shaped body 101. The disc-shaped body 101 has holes 103 through which two screws 3 that are screwed into two screw holes 353 are inserted, and two positioning holes 104 into which the two positioning protrusions 37 are inserted and positioned. The diameter of the disc-shaped body 101 is larger than the diameter of the holes 673. The retaining member 100 rotates left and right together with the lighting body 20 around the rotation axis O2, and when it has rotated by a predetermined amount, the restricted portion 102 comes into contact with the rotation restricting portion 674, thereby restricting the left and right rotation of the entire lighting body 20 beyond a predetermined amount. The mounting portion 35 has a pair of bulging portions 351 on the inner circumference of the central projection portion 331 that bulge towards the center. The pair of bulging portions 351 face each other in the X-axis direction and are connected to each other by a continuous portion 352. Two screw holes 353 are formed in the pair of bulging portions 351 along the X-axis direction, into which the retaining member 100 is screwed in by screws 3. The two positioning protrusions 37 face each other in a direction inclined with respect to the Y-axis direction in which the wiring 2 extends. Furthermore, the base portion 31 has a mounting portion 36 that is positioned on the inner circumference side of the outer cylindrical portion 322 and on the outer circumference side of the inner cylindrical portion 33. The mounting portion 36 has a mounting continuation portion 361 that connects the outer cylindrical portion 322 and the inner cylindrical portion 33 of the base body portion 32 at one position in the X-axis direction relative to the inner cylindrical portion 33, and a mounting continuation portion 362 that connects the outer cylindrical portion 322 and the inner cylindrical portion 33 of the base body portion 32 at the other position in the X-axis direction relative to the inner cylindrical portion 33. The mounting continuation portions 361 and 362 each have screw holes 363 that can be screwed in to attach other mounting devices having spike portions, which will be described later. Note that this mounting portion 36 is not used when attaching the lighting body to the mounting device 60, but it is used when attaching the lighting body 20 to other mounting devices, etc.

[0012] As shown in Figures 4 to 6, the case body 61 has a case front wall 62, a pair of case side walls 63 that are continuous with the case front wall 62 and extend toward the base body 71, and a pair of case end walls 64 that are continuous with the case front wall 62 and the pair of case side walls 63 and extend toward the base body 71. The front wall 62 of the case is formed in a roughly rectangular plate shape. The front wall 62 of the case has the aforementioned base mounting section 65, a mounting section 66 to which the swing restrictor 91 is attached, and a mounting projection 67 to which the tension stopper 95 is attached. The base mounting section 65, the mounting section 66, and the mounting projection 67 are each located inside the case body 61. The base mounting section 65 is formed in a concave shape, having a peripheral wall 651 continuous with the case front wall 62 and a bottom wall 652 continuous with the peripheral wall 651. The inner peripheral surface of the peripheral wall 651 is formed in a circular shape corresponding to the outer cylindrical portion 322 of the base body 32. In addition, a pair of drainage holes 653 are formed in the peripheral wall 651, extending from the surface of the case front wall 62 to the bottom wall 652 and opening at the surface of the case front wall 62. The pair of drainage holes 653 are arranged opposite each other in the Y-axis direction, with one drainage hole 653 located on the side of the peripheral wall 651 that is for the inlet wiring groove 68 and the other drainage hole 653 located on the side of the peripheral wall 651 that is for the outlet wiring groove 68. The bottom wall 652 has a circular hole 673 in which the central projection 331 of the inner cylindrical portion 33 is arranged to be rotatable left and right, and a rotation restricting portion 674 that protrudes toward the base body 71. The hole 673 has a diameter smaller than the diameter of the outer peripheral edge 332 of the inner cylindrical portion 33. The rotation restricting portion 674 is positioned so that the restricted portion 102 of the retaining member 100 can come into contact with it. The mounting portion 66 is positioned above (on one side) the base mounting portion 65 and is formed to protrude from the front wall 62 of the case toward the base body 71. The swing restrictor 91 is screwed to the mounting portion 66 by two screws 5. The mounting protrusion 67 is located on the lower side (the other side) with respect to the position of the pedestal placement portion 65 and is disposed at a substantially central position in the X-axis direction of the case body 61. It is formed to protrude from the case front wall 62 toward the base body 71 side, and its top surface is disposed on the base body 71 side rather than the rotation portion 10 described later in the Z-axis direction. Two screw holes 675 are formed in the mounting protrusion 67 in substantially the same manner as the mounting portion 35, and the tension stopper 95 is screwed by two screws 6 that are screwed into the screw holes 675. A pair of wiring through grooves 68 are respectively formed in the pair of case end walls 64, and the pair of wiring through grooves 68 are arranged to face each other in the Y-axis direction. The upper wiring through groove 68 (inlet side wiring through groove) is configured to allow the insertion of the wiring 2 drawn into the interior of the case body 61. It is formed larger in the front, rear, left, and right directions than the lower wiring through groove 68 (outlet side wiring through groove), and forms an interval that allows the oscillation of the wiring 2 accompanying the vertical and horizontal rotation (swinging) of the lamp unit 21. The bottom of the inlet side wiring through groove 68 and the screwing position of the swing restricting tool 91 with respect to the mounting portion 66 are substantially the same position in the Z-axis direction, and are positions spaced apart from the base body 71 in the Z-axis direction rather than the position of the bottom wall 652 of the pedestal placement portion 65 in the Z-axis direction. The outlet side wiring through groove 68 is configured to allow the insertion of the wiring 2 drawn out from the interior of the case body 61 to the outside. Here, the pedestal portion 31 and the pedestal placement portion 65 constitute a rotation portion 10 that allows the lamp unit 21 to rotate left and right around the rotation axis O2 along the Z-axis direction. The mounting portion 66 is disposed on the inlet side wiring through groove 68 side with respect to the rotation portion 10 in the Y-axis direction, and the mounting protrusion 67 is disposed on the outlet side wiring through groove 68 side with respect to the rotation portion 10 in the Y-axis direction. On the lower case end wall 64, a pair of screws 7 described later are disposed at positions on both the left and right sides with respect to the outlet side wiring through groove 68 formed therein, and this lower case end wall 64 is screwed to the base body 71 by the screws 7. In the attached state of the case body 61 to the base body 71, an internal space in which the wiring 2, the swing restricting tool 91, the tension stopper 95, the retaining member 100, etc. are disposed is formed between the case body 61 and the base body 71.

[0013] Here, as shown in FIGS. 2 and 4 to 6, the rocking restrictor 91 includes a substantially rectangular substrate portion 911 along the X-axis direction, a pair of engaging piece portions 912 extending in the Z-axis direction from both side edges along the Y-axis direction of the substrate portion 911 toward the base body 71, and a rocking restricting piece portion 913 extending in the Z-axis direction from the lower edge along the X-axis direction of the substrate portion 911 at a position between the pair of engaging piece portions 912 toward the base body 71. The engaging piece portion 912 has an engaging portion 912A protruding downward, and the rocking restricting piece portion 913 has a semi-circular wiring restricting surface 914 in plan view as shown in FIG. 6. The wiring restricting surface 914 abuts against the wiring 2 at the bottom portion 914A in the Z-axis direction to restrict the rocking of the wiring 2 toward the front side (the electric lamp portion 21 side). Further, the wiring restricting surface 914 is arranged at an interval from the wiring 2 in the X-axis direction, allowing the wiring 2 to rock in the X-axis direction by the amount of the interval, and abutting against the wiring 2 for rocking in the X-axis direction more than the interval to restrict the rocking more than the interval. Note that the rocking restrictor 91 shown in FIG. 2 is shown on the base body 71 side of the wiring 2 for convenience of explanation, but in reality, it is mounted on the mounting portion 66 before the wiring 2 is arranged as shown in FIG. 4 or the like. Also, the tension stopper 95 is a metal fitting having a pair of clamping piece portions 41 facing each other in the X-axis direction, and fixes the wiring 2 by clamping the wiring 2 with the pair of clamping piece portions 41 so that the wiring 2 does not move even if it is pulled, for example, when the wiring 2 is stepped on.

[0014] The base body 71 is composed of a metal plate material fixed to a wall, a pillar, or the like by a fixture such as bolts and nuts. A plurality of holes 74 for fixing to a wall, a pillar, or the like by screwing or the like are formed in the base body 71. A cushion sheet 72 or the like is interposed between the base body 71 and an outdoor structure such as a wall or a pillar so as not to damage the outdoor structure. The base body 71 is a metal fitting having a plate-shaped body 731, a pair of engaging portions 732 extending from the upper edge of the plate-shaped body 731 toward the front wall 62 of the case and into which the engaging piece 912 of the swing restrictor 91 is engaged, and a pair of fixing portions 733 extending from the lower edge of the plate-shaped body 731 toward the front wall 62 of the case and into which the case body 61 is fixed by screws 7 as fasteners, the fixing portions 733 are positioned below the engaging portions 732. A large-diameter hole 734 is formed in the approximate center of the plate-shaped body 731, large enough for the wiring 2 to be sufficiently inserted. The pair of engaging portions 732 are positioned opposite each other with a distance between them in the X-axis direction. The engaging portions 732 have engaging holes 735 into which the engaging portion 912A of the engaging piece 912 of the swing restrictor 91 is engaged. The pair of fixing portions 733 each have screw holes 736 into which screws 7 (see Figure 8) are screwed. In this base body 71, the case body 61 on which the lighting unit 20 is installed can be temporarily positioned by hanging it on the base body 71 by engaging the engaging piece 912 of the swing restrictor 91 with the engaging part 732, and the case body 61 can be attached to the base body 71 by screwing the lower case end wall 64 to the fixing part 733 with a screw 7 in this temporarily positioned state.

[0015] The mounting structure of the lighting unit 20 to the mounting fixture 60 is as follows: The base portion 31 of the lighting body 20 is positioned to rotate left and right around the rotation axis O2 relative to the base mounting portion 65 of the case body 61, the central projection 331 is positioned in the hole 673 of the bottom wall 652, and the retaining member 100 is attached to the mounting portion 35 by screwing a screw 3 into the screw hole 353. An annular resin plate 111 is positioned between the outer peripheral edge 332 of the inner cylindrical portion 33 and the bottom wall 652, a disc-shaped resin plate 112 is positioned between the central projection 331 and the retaining member 100, and an elastically deformable rubber O-ring 113 is positioned in the annular groove portion 333. The resin plate 111 reduces sliding resistance compared to the case where the die-cast outer peripheral edge 332 and the die-cast bottom wall 652 slide directly against each other. The resin plate 112 reduces sliding resistance compared to the case where the die-cast bottom wall 652 and the retaining member 100, which is a metal fitting, slide directly against each other. The O-ring 113 undergoes elastic deformation as the screw 3 is screwed into the screw hole 353, and this elastic force is used to moderately increase the sliding resistance between the base portion 31 and the base mounting portion 65. In the lighting device 1 of this embodiment, the aforementioned rotating part 10 is constructed so that the lighting body 20 can rotate left and right relative to the mounting tool 60 by assembling the base part 31, the base mounting part 65, and the retaining member 100 using screws 3, resin plates 111, 112, and O-rings 113.

[0016] The wiring 2 is positioned to overlap the aforementioned rotating part 10 in the Z-axis direction. The restricted position P1 of the wiring 2, where its oscillation is restricted by the oscillation restrictor 91 and particularly its forward oscillation by the bottom part 914A, and the fixed position P2 of the wiring 2, where it is fixed by the tension stopper 95, are both located on the base body 71 side relative to the rotating part 10 in the Z-axis direction. Therefore, the rotating part 10 is positioned on the light unit 21 side in the Z-axis direction relative to the wiring 2, which is restricted from oscillation by the oscillation restrictor 91 and fixed by the tension stopper 95, thereby suppressing interference between the wiring 2 and the rotating part 10. Preferably, a gap of about 1 mm is formed between the wiring 2 and the rotating part 10.

[0017] [Differentiation] In the above embodiment, the wiring restricting surface 914 of the swing restricting device 91 is positioned at a distance from the wiring 2 in the Z-axis direction. However, if the light unit 21 can be configured to rotate up, down, left, and right within a sufficient range, it may be configured without such a distance. In the above embodiment, the swing restrictor 91 is configured to be engageable with the base body 71, but this configuration may be omitted, and the upper case end wall 64 may be screwed to the base body 71. In the above embodiment, the wiring 2 is fixed by a tension stopper 95 that clamps the wiring 2 with a pair of clamping pieces 41. However, the invention is not limited to this, and any wiring stopper that can fix the wiring 2 so that the light unit 21 does not sway even when the wiring 2 is pulled may be used, and it does not have to be a configuration like the tension stopper 95 having a pair of clamping pieces 41. In the above embodiment, the tension stopper 95 and the retaining member 100 are screwed into the mounting portion 35 and the mounting projection 67 by screwing screws 3 and 6 into two screw holes 353 and 675. However, the configuration may involve screwing into three or more screw holes, or screwing into a single screw hole, as long as the tension stopper 95 and the retaining member 100 are secured in a functional manner. In the above embodiment, the wiring 2 is inserted through the inlet wiring groove 68 and then through the outlet wiring groove 68 to pass through the case body 61. However, the configuration is not limited to this, and for example, if the wall or column to which the mounting device 60 is installed is hollow, the wiring 2 may not be inserted through the outlet wiring groove 68, but instead passed through the large-diameter hole 734 of the base body 71. In this case, the tension stopper 95 may be omitted. In the above embodiment, the base body 71 is fixed to an outdoor structure such as a wall or column, a swing restrictor 91 is attached to the base body 71, and the lower case end wall 64 is configured to be screwed to the base body 71 to form a wall-mounted lighting device 1. However, the lighting device 1 is not limited to this, and may also be installed on the floor or ceiling surface of an outdoor structure that has a floor or ceiling surface. For example, when the lighting device 1 is installed on the ceiling surface as shown in Figure 8, rainwater or other water that enters the inside of the case body 61 from the wiring groove 68 is drained through the inside of the case body 61 and out of the drain hole 653 as shown by arrow 8. When installed in this way, the X, Y, and Z axis directions will be different from the lighting device 1 that is mounted on a wall or column as in the above embodiment, and each direction will be as shown in Figure 8, for example. The lighting body 20 in the above embodiment can be used as is with other mounting devices different from the mounting device 60. For example, when using the lighting body 20 with another type of mounting device that has a spike portion inserted into the ground, the other mounting device can be attached to the mounting portion 36 of the base portion 31 by screws or the like instead of the mounting device 60 to constitute another form of lighting device. In this case, if the wiring 2 is passed through the other mounting device, a tension fastener 95 for fixing the wiring 2 may be screwed to the mounting portion 35 of the base portion instead of the retaining member 100. When attaching the tension fastener 95 to the mounting portion 35, it is preferable that the positioning projection 37 is positioned away from the wiring 2 that passes through the inside of the case body 61 and is positioned to guide the tension fastener 95 to a predetermined position.

[0018] In the above embodiment, one drain hole 653 is located on the inlet wiring groove 68 side and the other drain hole 653 is located on the outlet wiring groove 68 side. However, the invention is not limited to this configuration, and if sufficient drainage performance can be obtained, for example, a pair of drain holes 653 may be arranged facing each other in the X-axis direction. Furthermore, although a pair of drain holes 653 are formed in the peripheral wall 651 of the base mounting portion 65, the invention is not limited to this configuration. For example, if sufficient drainage performance can be obtained, only one drain hole may be formed, or three or more drain holes may be formed to improve drainage performance. In the above embodiment, the drainage hole 653 extends from the front wall 62 of the case to the bottom wall 652, but it is not limited to this shape and may be any other shape as long as it opens at the front wall 62 of the case and allows drainage. In the above embodiment, the mounting device 60 is equipped with a swing restrictor 91 and a tension stopper 95. However, these components may be omitted if, for example, there are no problems in terms of the routing of the wiring 2 of the lighting device 1 or in terms of performance. In this case, the mounting portion 66 and the mounting projection 67 may also be omitted.

[0019] [Summary of the invention] The lighting device of the present invention comprises a lamp unit through which wiring is brought out to the outside, a base unit connected to the lamp unit, and a case body having a concave base unit that is rotatably positioned on the base unit and having the wiring arranged inside, wherein the base unit and the base unit unit constitute a rotating part that makes the lamp unit rotatable, and the case body has an entry-side wiring groove through which the wiring being pulled into the inside of the case body is inserted, an exit-side wiring groove through which the wiring being pulled out from the inside of the case body is inserted, and in the direction in which the wiring is inserted into the case body The rotating portion is provided with a mounting portion that is positioned on the input side wiring groove and to which a swing restricting device is attached to restrict the swinging of the wiring, and a mounting projection that is positioned on the output side wiring groove relative to the rotating portion in the insertion direction and to which a wiring fastener is attached to fix the wiring, and the restricted position of the wiring whose swinging is restricted by the swing restricting device and the fixed position of the wiring whose fixing is fixed by the wiring fastener are positioned on the opposite side of the rotating portion from the base portion in the front-rear direction perpendicular to the insertion direction. According to the lighting device of the present invention, since the wiring that is pulled out from the light unit to the outside is arranged inside the case, it is not necessary to provide wiring connection points inside the case or to apply waterproofing treatment to these parts, thereby suppressing the increase in size of the lighting device. In addition, since the restricting position and fixing position of the wiring are located on the opposite side of the base from the rotating part in the front-to-back direction, interference of the wiring with the rotating part can be suppressed even if the wiring is fixed inside the case.

[0020] In the lighting device of the present invention, the oscillation restrictor has a wiring restricting surface that restricts the oscillation of the wiring toward the lamp unit in the front-rear direction and the oscillation in the width direction perpendicular to the insertion direction and the front-rear direction, and the wiring restricting surface may be arranged at a distance from the wiring in the width direction. With this configuration, the oscillation restrictor reduces the risk of the wiring interfering with the rotating part by restricting the oscillation of the wiring toward the light fixture with its wiring restricting surface. Furthermore, since the wiring restricting surface is positioned at a distance from the wiring in the width direction, it is possible to allow oscillation in the width direction (left-right direction) of the wiring only within the distance of the gap, and to restrict oscillation beyond that distance. In addition, when attaching the case to an outdoor structure such as a wall or column, restricting the oscillation of the wiring with the wiring restricting surface prevents the wiring from being positioned in an unintended location, which would make it difficult to attach the case.

[0021] The lighting device of the present invention includes a base body to which the case body is attached, the swing restrictor has an engaging piece that protrudes toward the base body, and the base body may have an engaging portion into which the engaging piece is engaged, and a fixing portion formed below the engaging portion into which the case body is fixed by a fixing device. With this configuration, first, the case body to which the swing restrictor is attached can be temporarily positioned relative to the base body by engaging the engaging portion of the swing restrictor with the engaging portion of the base body, and then the case body can be permanently fixed to the base body by fixing it to the fixing portion with the fixing device. By attaching the case body to the base body in this way, compared to, for example, the case body is attached to the base body only by the fixing device without engaging the restrictor portion of the swing restrictor with the base body, the case body can be attached to the base body more easily because it can be temporarily positioned, thereby improving workability.

[0022] Furthermore, the lighting device of the present invention comprises a lighting body and an installation device to which the lighting body is attached, the lighting body having a light unit from which wiring is pulled out to the outside and a base unit connected to the light unit, the installation device having a case body having a concave base unit on the front wall of the case in which the base unit is rotatably positioned and the wiring is arranged inside, the base unit and the base unit unit constitute a rotating part that makes the light unit rotatable, the case body has a wiring groove through which the wiring is inserted, the base unit unit has a peripheral wall continuous with the front wall of the case and a bottom wall continuous with the peripheral wall, and the peripheral wall has at least one drain hole that opens at the front wall of the case. According to the present invention, by attaching a case to the ceiling surface of an outdoor structure, a lighting device in which the lighting unit and its base can rotate together can be installed on the ceiling surface. Furthermore, while water may enter the case through the wiring channel due to rain and wind, if the lighting device is installed on the ceiling, the water inside the case can be drained through the aforementioned drainage holes opened in the downward-facing front wall of the case. This prevents water from accumulating inside the fixture when it is installed on the ceiling of an outdoor structure. Furthermore, the lighting device can be installed not only on the ceiling surface but also on outdoor walls, columns, and other surfaces.

[0023] In the lighting device of the present invention, the front wall of the case is formed with a mounting portion on which a swing restricting device that restricts the swinging of the wiring inside the case body is mounted, and a mounting projection on which a wiring fastener that fixes the wiring inside the case body is mounted, and the mounting portion and the mounting projection may protrude from the front wall of the case on the side opposite to the lighting body. With this configuration, even when the lighting device is installed on the ceiling of an outdoor structure, the oscillation restriction device is attached to the mounting part, and the wiring fastener is attached to the mounting projection, thereby suppressing the oscillation of the wiring caused by the rotation of the light fixture and unintended swaying of the light fixture due to the tension of the wiring. Furthermore, since the mounting part and mounting projection protrude from the front wall of the case toward the base body, the mounting hardware, such as the oscillation restriction device and wiring fastener, can be positioned to prevent them from getting wet when the lighting device is installed on the ceiling of an outdoor structure.

[0024] In the lighting device of the present invention, the case body has a front wall, a pair of side walls continuous with the front wall, and a pair of end walls continuous with the front wall and the pair of side walls, the wiring grooves are formed in each of the pair of end walls, and at least a pair of drainage holes are formed in the peripheral wall of the base mounting portion, one of the pair of drainage holes may be located in the portion of the peripheral wall on the wiring groove side formed on one of the pair of end walls, and the other of the pair of drainage holes may be located in the portion of the peripheral wall on the wiring groove side formed on the other of the pair of end walls. With this configuration, when the lighting device is installed on the ceiling surface of an outdoor structure, if water enters through the wiring groove formed in one of the pair of case end walls, the water can be quickly drained from the drain hole located on the wiring groove side, and if water enters through the wiring groove formed in the other of the pair of case end walls, the water can be quickly drained from the other drain hole located on the wiring groove side. Furthermore, when the lighting device is installed on an outdoor wall or column, water that seeps in through the wiring groove formed on one of the pair of case end walls (upper) can be drained through the wiring groove formed on the other of the pair of case end walls (lower). Note that even if the lighting device is mounted upside down relative to the wall or column as described above, drainage from the wiring groove can be achieved in roughly the same manner.

[0025] In the lighting device of the present invention, the lamp unit has a main body having a front portion and a rear portion, and a bearing portion attached to the main body and rotatably connected to the base portion, the rear portion has a rear cylindrical portion having a notch in which the bearing portion is arranged, and a rear bottom portion that closes the rear cylindrical portion on the front portion side and through which the wiring is pulled out, the rear bottom portion has a water reservoir portion on its bottom surface that is closer to the front portion side, and the bottom surface of the notch may be positioned flush with the bottom surface of the water reservoir portion or closer to the front portion side than the bottom surface of the water reservoir portion. With this configuration, when the lighting device is attached to an outdoor structure such as a wall or column, and the direction of the light from the lamp is facing downwards, even if rainwater or other liquids enter a puddle on the back of the lamp, the rainwater or other liquids can be smoothly drained through the notch configured as described above. Therefore, the risk of rainwater or other liquids accumulating around the wiring coming out from the back and entering the lamp from this area can be reduced. [Explanation of Symbols]
