Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, as exterior lighting devices, there are various installation tools corresponding to plug - in types that insert a spike portion into the ground like the exterior lighting device described in Patent Document 1, and wall - mounted types that are hung on an outdoor wall portion or the like. It is desirable that the lighting body can be used in common with various installation tools. However, for example, when making it wall - mounted, there may be a case where it is desired to configure the lamp unit to be rotatable not only vertically but also horizontally. In such a case, it is difficult to directly use the lighting body in the exterior lighting device described in Patent Document 1, and it is difficult to make the lighting body versatile.

[0005] The object of the present invention is to provide a lighting device and a lighting body that can also be used as a lighting body for various types of mounting fixtures. [Means for solving the problem]

[0006] The present invention provides a lighting device comprising a lighting body, a first mounting device to which the lighting body is mounted so as not to rotate left or right, or a second mounting device to which the lighting body is mounted so as to rotate left or right, wherein the lighting body has a lamp section from which wiring is brought out to the outside, a connecting section to which the lamp section is connected so as to rotate up and down, and a base section continuous with the connecting section, wherein the base section has an outer circular base body section, an outer circular central projection section projecting downward from the center of the base body section, a mounting section formed on the lower surface of the central projection section so as to be able to attach a retaining member having a larger diameter than the central projection section, and a mounting section formed on the outer circumference side of the central projection section and capable of attaching the first mounting device, wherein the second mounting device has a concave base arrangement section in which the base body section is arranged so as to rotate left or right and which has a hole in which the central projection section is arranged. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a lighting device and a lighting body that can also be used as a lighting body for various types of mounting fixtures. [Brief explanation of the drawing]

[0009] [First Embodiment] Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. In Figures 1(A), 2, and 3, the lighting device 1 according to the first embodiment is a plug-in type outdoor lighting device that is installed by inserting it into the ground, such as in a garden. This lighting device 1 comprises a lighting body 20 and an installation tool 50 (first installation tool) to which the lighting body 20 is attached so as not to rotate left or right. The lighting body 20 has a light unit 21 from which wiring 2 is pulled out to the outside, and a die-cast base 31 on which a connecting part 25 is formed, to which the light unit 21 is connected so as to be vertically rotatable. The installation tool 50 has a mounting part 51 that is attached to the lighting body 20, and a spike part 56 that extends downward from the mounting part 51 and can be inserted into the ground. In the following description, the left-right 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. Figure 1(A) shows the lighting device 1 of the first embodiment, and Figure 1(B) shows the lighting device 1B of the second embodiment, which will be described later.

[0010] The light unit 21 of the lighting body 20 has a light source (not shown) such as an LED that illuminates from the front of the housing 22 inside the housing 22, and wiring 2 is brought out to the outside from the back of the housing 22. A bearing portion 23 is formed on the circumferential surface of the housing of the light unit 21, which is connected to the connecting portion 25. The light unit 21 is waterproofed on its own, so there is no need to waterproof the connecting portion 25, the base portion 31, and the installation equipment 50.

[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 to 5, 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 3) formed on which the aforementioned connecting portion 25 extends upward, and it connects with the bearing portion 23 (see Figure 3) 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 (swivel) about the rotational axis O1 relative to the connecting section 25. The vertical direction of the light emitted by the light unit 231 is adjusted by this vertical rotation. The inner cylindrical portion 33 protrudes downward from the center of the top plate 321, and the lower edge of its outer peripheral edge 332 is positioned 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 downward from 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 in the second embodiment, can be placed. Furthermore, the base portion 31 has a mounting portion 35 on the lower surface 34 of the central projection 331 to which a tension fastener 40, which serves as a wiring fastener for fixing the wiring 2, can be attached, and a mounting portion 36 to which the installation tool 50 is attached is formed on the inner circumference side of the outer cylindrical portion 322 and on the outer circumference side of the inner cylindrical portion 33, and two positioning protrusions 37 are formed on the lower surface 34 of the central projection 331 to position and guide the tension fastener 40 to a predetermined position away from the wiring 2. The tension fastener 40 is a metal fitting having a pair of clamping pieces 41 facing each other in the X-axis direction, and by clamping the wiring 2 with the pair of clamping pieces 41, the wiring 2 is fixed so that it does not move even if it is pulled, for example by being stepped on. The mounting portion 35 has a pair of bulging portions 351 on the inner circumference of the central projection portion 331, which bulge outwards 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 along the Y-axis direction in the pair of bulging portions 351, into which tension fasteners 40 that hold the wiring 2 are screwed in by screws 3, and the wiring 2 held by the tension fasteners 40 is positioned between them in the X-axis direction. In addition to the tension fasteners 40, the retaining members 100 (see Figures 8 and 9) in the second embodiment described later can also be screwed into these two screw holes 353. The two positioning protrusions 37 face each other in a direction inclined with respect to the Z-axis direction from which the wiring 2 extends. As shown in Figure 5, these two positioning protrusions 37 are positioned away from the wiring 2 fixed by the tension fastener 40, and are positioned to guide the tension fastener 40 to a predetermined position. 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 a position on one side 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 a position on the other side in the X-axis direction relative to the inner cylindrical portion 33. Screw holes 363 are formed in the mounting continuation portions 361 and 362, respectively, into which the mounting tool 50 is screwed in by screws 4.

[0012] The mounting portion 51 of the installation device 50 has a roughly disc-shaped lower plate portion 52, a roughly cylindrical cylindrical portion 53 extending upward from the periphery of the lower plate portion 52, and a stopper portion 54 formed by recessing a part of the lower plate portion 52 and the cylindrical portion 53 from the outer circumference. The cylindrical portion 53 has a pair of wiring grooves 55 (first wiring grooves) facing each other in the Z-axis direction. The stopper portion 54 is screwed to the mounting portion 36 by screws 4 that are screwed into screw holes 363. In this screwed state, the pair of wiring grooves 55 are positioned with the inner cylindrical portion 33 between them in the Z-axis direction, and the wiring 2 is inserted through them. When mounted to the mounting portion 36, the mounting portion 51 forms an internal space between itself and the base portion 31 in which the wiring 2 and tension fastener 40 are positioned. The spike portion 56 is cruciform and is formed to taper downward, with its lower end being a pointed tip. This spike portion 56 is configured to have a shape that is easy to insert into the ground, such as in a garden. Incidentally, the lower surface of the aforementioned lower plate portion 52 functions as a grounding surface that defines the insertion amount.

[0013] In the lighting device 1 described above, since the wiring 2 drawn out from the electric lamp portion 21 to the outside is fixed to the pedestal portion 31 by the tension stopper 40, there is no need to provide a configuration for connecting the wiring to the electric lamp portion 21 in the pedestal portion 31 or to perform waterproofing treatment on the wiring in the pedestal portion 31. Therefore, the pedestal portion 31 can be simplified and miniaturized. Further, the wiring 2 is curved from the electric lamp portion 21 side, fixed to the lower surface 34 of the inner cylindrical portion 33 by the tension stopper 40, and inserted through a pair of wire passage grooves 55 facing each other in the Z-axis direction. Therefore, for example, there is no need to forcibly bend the wiring 2 so as to avoid the inner cylindrical portion 33, and the wiring 2 can be easily arranged.

[0014] [Second Embodiment] Hereinafter, a second embodiment of the present invention will be described based on the drawings. In FIGS. 1(B), 6, and 7, the lighting device 1B according to the second embodiment is a wall-mounted lighting device for an exterior structure that is fixed to walls, pillars, etc. around a building. This lighting device 1B includes a lighting main body 20 and an installation tool 60 (second installation tool) that can be attached to rotate left and right. The lighting main body 20 is the same as the one used in the first embodiment, and a detent member 100 described later is attached to the mounting portion 35 instead of the tension stopper 40. The installation tool 60 includes a die-cast case body 61 having a pedestal arrangement portion 65 where the pedestal main body portion 32 of the lighting main body 20 is arranged to be rotatable left and right, a base body 71 to which the case body 61 is attached, a swing restricting tool 91 that is a fitting for restricting the swing of the wiring 2 inside the case body 61, and a tension stopper 95 that is a fitting for fixing the wiring 2 inside the case body 61. The base body 71 is fixed to a wall, a pillar, etc. The case body 61 forms an internal space between itself and the base body 71 where the wiring 2, the swing restricting tool 91, the tension stopper 95, the detent member 100 described later, etc. are arranged in a state of being attached to the base body 71. Note that since the lighting main body 20 also uses the same one as in the first embodiment, the detailed description of the lighting main body 20 is omitted in the second embodiment. In the following description, the left-right direction of the lighting device 1B is defined as the X-axis direction, the up-down direction of the lighting device 1B 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.

[0015] As shown in FIGS. 8 and 9, the case body 61 of the installation tool 60 has a case front wall 62, a pair of case side walls 63 that extend continuously from the case front wall 62 toward the base body 71 side, and a pair of case end walls 64 that extend continuously from the case front wall 62 and the pair of case side walls 63 toward the base body 71 side. The case front wall 62 is formed in a rectangular plate shape. This case front wall 62 has the pedestal arrangement portion 65 described above, a mounting portion 66 to which the swing restricting tool 91 is attached, and a mounting protrusion 67 to which the tension stopper 95 is attached. The pedestal arrangement portion 65, the mounting portion 66, and the mounting protrusion 67 are respectively arranged 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 located, 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 it can come into contact with the restricted portion 102 of the retaining member 100, which will be described later. 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 projection 67 is located below (on the other side of) the position of the base mounting portion 65 and is positioned approximately in the center of the case body 61 in the X-axis direction. It is formed to protrude from the front wall 62 of the case toward the base body 71, and its top surface is positioned toward the base body 71 in the Z-axis direction, relative to the base mounting portion 65, the retaining member 100, and the screws 3. The mounting projection 67 has two screw holes 675 formed therein, similar to those of the mounting portion 35, and the tension retainer 95 is screwed in by two screws 6 that are threaded into the screw holes 675. A pair of wiring grooves 68 (second wiring grooves) are formed in each of the case end walls 64, and the pair of wiring grooves 68 are arranged opposite each other in the Y-axis direction. The upper wiring groove 68 (inlet wiring groove) is configured to allow the wiring 2 that is drawn into the interior of the case body 61 to be inserted, and is formed to be larger in the Z-axis direction than the lower wiring groove 68, creating a gap that allows the wiring 2 to swing in conjunction with the up, down, left, and right rotation (swinging) of the light unit 21. The bottom of the inlet wiring groove 68 and the screw fastening position of the mounting portion 66 of the swing restrictor 91 are in approximately the same position in the Z-axis direction, and are located further away from the base body 71 than the position of the bottom wall 652 of the base mounting portion 65 in the Z-axis direction. The exit wiring groove 68 is configured to allow wiring 2, which is pulled from the inside of the case body 61 to the outside, to be inserted. Here, the base portion 31 and the base mounting portion 65 constitute a rotating portion 10 that allows the light unit 21 to rotate left and right around a rotation axis O2 along the Z-axis direction, the mounting portion 66 is positioned on the side of the entry wiring groove 68 relative to the rotating portion 10 in the Y-axis direction, and the mounting projection 67 is positioned on the side of the exit wiring groove 68 relative to the rotating portion 10 in the Y-axis direction. On the lower case end wall 64, a pair of screws 7, described later, are positioned on both the left and right sides relative to the wiring pass-through groove 68 formed therein, and this lower case end wall 64 is screwed to the base body 71 by the screws 7. When the case body 61 is mounted on the base body 71, it forms an internal space between itself and the base body 71 in which the wiring 2, swing restrictor 91, tension stopper 95, retaining member 100, etc., are arranged.

[0016] Here, the swing restricting device 91 is a metal fitting having a base plate portion 911 along the X-axis direction, a pair of engaging pieces 912 extending from both side edges of the base plate portion 911 along the Y-axis direction toward the base body 71 in the Z-axis direction, and a swing restricting piece 913 extending from the lower edge of the base plate portion 911 along the X-axis direction toward the base body 71 in the Z-axis direction, located between the pair of engaging pieces 912. The engaging pieces 912 have an engaging portion 912A that protrudes downward, and the swing restricting piece 913 has a semicircular wiring restricting surface 914 in a plan view, and the wiring restricting surface 914 contacts the wiring 2 with its bottom portion 914A in the Z-axis direction, thereby restricting the swing of the wiring 2 toward the front side (towards the light fixture 21 side). Furthermore, the wiring restricting surface 914 is positioned at a distance from the wiring 2 in the X-axis direction, allowing the wiring 2 to swing in the X-axis direction by the amount of that distance, and restricting swings in the X-axis direction exceeding that distance by contacting the wiring 2. Note that the swing restricting device 91 shown in Figure 7 is shown on the base body 71 side of the wiring 2 for the sake of explanation, but in reality it is attached to the mounting part 66 before the wiring 2 is positioned as shown in Figure 7. Also, the tension stopper 95 is configured in the same way as the tension stopper 40 described above, so its details are omitted.

[0017] The base body 71 is made of a metal plate that is fixed to walls, columns, etc., by fasteners such as bolts and nuts. Multiple holes 74 are formed in this base body 71 for fixing to walls, etc., by screws, etc. A cushion sheet 72 or the like is interposed between this base body 71 and the outdoor structure such as a wall or column to prevent damage to 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 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, to which the case body 61 is fixed by screws 7 acting 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 gap 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 pieces 733 each have screw holes 736 into which the screws 7 shown in Figure 6 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.

[0018] The mounting structure of the lighting unit 20 to the mounting fixture 60 is as follows: The base portion 31 of the lighting unit 20 is positioned to rotate left and right around a rotation axis O2 along the Z-axis relative to the base mounting portion 65 of the case body 61, the central projection 331 is positioned in a hole 673 in the bottom wall 652, and the mounting portion 35 is fitted with a retaining member 100 that prevents the base portion 31 from coming off the base mounting portion 65 by screwing a screw 3 into a screw hole 353. 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 (not shown) through which two screws 3 that are screwed into two screw holes 353 are inserted, and two positioning holes 104 into which two positioning projections 37 are inserted and positioned. The diameter of the disc-shaped body 101 is larger than the diameter of the holes 673. This retaining member 100 rotates left and right around the rotation axis O2 together with the lighting body 20, 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. Furthermore, an annular resin plate 111 is positioned between the outer peripheral edge 332 and the bottom wall 652 of the inner cylindrical portion 33, 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 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 when the screw 3 is screwed into the screw hole 353, and the restoring force at this time is used to appropriately increase the sliding resistance between the base portion 31 and the base mounting portion 65. In the lighting device 1B of this embodiment, as described above, the base portion 31, the base mounting portion 65, and the retaining member 100 are assembled using screws 3, resin plates 111, 112, and O-rings 113 to form a rotating portion 10 that allows the lighting body 20 to rotate left and right relative to the mounting tool 60.

[0019] 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 movement by the bottom part 914A, and the fixed position P2 of the wiring 2, where it is fixed by the tension stopper, 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, whose oscillation is restricted by the oscillation restrictor 91 and fixed by the tension stopper 95, thereby suppressing interference between the wiring 2 and the rotating part 10. In addition, it is preferable that a gap of about 1 mm is formed between the wiring 2 and the rotating part 10.

[0020] [Differentiation] Since the lighting body 20 in the first and second embodiments is the same, it can be used interchangeably. For example, the lighting body 20 in the lighting device 1 of the first embodiment may be used as the lighting body 20 in the lighting device 1 of the second embodiment, or conversely, the lighting body 20 of the lighting device 1 of the second embodiment may be used as the lighting body 20 in the lighting device 1 of the first embodiment. In the first embodiment, the light unit 21 is configured to rotate vertically relative to the mounting fixture 50. However, the embodiment is not limited to this, and a base arrangement portion similar to the base arrangement portion 65 may be configured on the mounting portion 51 of the mounting fixture 50, and the base portion 31 of the lighting body 20 may be placed thereon. By preventing it from coming off with a retaining member similar to the retaining member 100, the light unit 21 can be configured to rotate not only vertically but also horizontally relative to the mounting fixture 50. In this case, the tension retainer 40 is attached to the mounting fixture 50 side rather than the mounting portion 35. In the first and second embodiments, a positioning projection 37 is formed on the central projection 331. However, the positioning projection 37 may be omitted if the tension stopper 40 and the retaining member 100 can be attached to the mounting portion 35. In this case, the positioning hole 104 of the retaining member 100 may also be omitted. In the first and second embodiments, the wiring 2 is fixed by tension fasteners 40 and 95 that clamp the wiring 2 with a pair of clamping pieces 41. However, the invention is not limited to this, and any wiring fastener that can fix the wiring 2 so that the light fixture 21 does not sway even when the wiring 2 is pulled may be used, and does not necessarily have to be configured as tension fasteners 40 and 95 having a pair of clamping pieces 41. In the first and second embodiments, the tension fasteners 40 and 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 fasteners 40 and 95 and the retaining member 100 are secured in a functional manner. In the second embodiment, the wiring 2 is inserted through the upper wiring groove 68 and then through the lower 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 lower wiring groove 68, but a hole may be formed in the base member 72, and the wiring 2 may be passed through this hole and the large-diameter hole 734 of the engaging member 73. In this case, the configuration of the tension stopper 95 may be omitted. In the second embodiment, the lighting device 1B is installed as a wall-mounted type, but it is not limited to this and may be installed on the ceiling surface of an outdoor structure, etc.

[0021] [Summary of the invention] The present invention provides a lighting device comprising a lighting body, a first mounting device to which the lighting body is mounted so as not to rotate left or right, or a second mounting device to which the lighting body is mounted so as to rotate left or right, wherein the lighting body has a lamp section from which wiring is brought out to the outside, a connecting section to which the lamp section is connected so as to rotate up and down, and a base section continuous with the connecting section, wherein the base section has an outer circular base body section, an outer circular central projection section projecting downward from the center of the base body section, a mounting section formed on the lower surface of the central projection section so as to be able to attach a retaining member having a larger diameter than the central projection section, and a mounting section formed on the outer circumference side of the central projection section and capable of attaching the first mounting device, wherein the second mounting device has a concave base arrangement section in which the base body section is arranged so as to rotate left or right and which has a hole in which the central projection section is arranged. According to the lighting device of the present invention, by attaching the first mounting device to the mounting part, a lighting device can be configured that includes a lighting body and the first mounting device, and in which the light unit can be rotated up and down. Furthermore, by placing the base body of the lighting unit in the base placement section of the second mounting device and the central protrusion in the hole of the base placement section, and attaching the retaining member to the mounting section, a lighting device can be constructed that includes the lighting unit and the second mounting device, and in which the light unit can be rotated up, down, left, and right. Furthermore, the first and second mounting fixtures can be attached to the lighting unit without changing its configuration. In other words, the lighting unit can be used interchangeably with both the first and second mounting fixtures.

[0022] In the lighting device of the present invention, the mounting portion is formed on the lower surface of the central projection so that a wiring fastener or a retaining member for fixing the wiring can be attached to it, the first mounting tool has a pair of first wiring grooves arranged in a position with the central projection between them so that the wiring can be inserted when mounted to the mounting portion, and the second mounting tool may have a pair of second wiring grooves through which the wiring can be inserted, and a fastener for fixing the wiring inserted into the second wiring grooves. According to the lighting device of the present invention, when the lighting device is composed of a lighting body and a first mounting device, the wiring from the light unit is fixed to the central protrusion by attaching a wiring fastener to the mounting part, and when attaching the first mounting device to the mounting part, the wiring is inserted into a pair of first wiring grooves, thereby enabling a configuration in which the wiring is fixed by the lighting device alone. For example, even if a tensile force is applied to the wiring, such as by stepping on it, the tensile force is not transmitted to the light unit, thus preventing the light unit from unintentionally rotating (swinging) due to this tensile force. Furthermore, when the lighting device consists of a lighting unit and a second mounting device, the wiring can be inserted into a pair of second wiring grooves and secured with fasteners, thus enabling a configuration where the wiring is fixed within the lighting device itself, as described above. In this configuration, even if a tensile force is applied to the wiring, for example by stepping on it, the tensile force will not be transmitted to the light unit, thus preventing the light unit from unintentionally rotating (swinging) due to this tensile force.

[0023] In the lighting device of the present invention, the central protruding portion is formed with a positioning projection that guides the wiring fastener to a position detached from the wiring when the wiring fastener is attached to the mounting portion, and the retaining member may be formed with a positioning hole that is positioned on the positioning projection when the retaining member is attached to the mounting portion. With this configuration, when attaching a wiring fastener to the mounting part, a positioning projection is formed at a position away from the wiring fixed to the wiring fastener. This allows for a configuration where the positioning projection does not interfere with the placement of the wiring, and the positioning projection guides the wiring fastener when attaching it to the mounting part, making it easy to position and improving workability. Furthermore, when a retaining member is attached to the mounting part, the positioning member can be placed in the positioning hole, allowing the retaining member to be easily positioned and improving workability.

[0024] In the lighting device of the present invention, the wiring fastener is composed of a tension fastener that clamps the wiring, and the mounting portion has two screw holes into which the tension fastener is screwed, and the two screw holes may be positioned so as to be sandwiched between the wiring that is clamped by the tension fastener. With this configuration, when the tension fastener is screwed into two screw holes, the screw fastening points can be positioned so that they do not interfere with the wiring even when the wiring is being held by the tension fastener, and the predetermined mounting orientation relative to the central protrusion of the tension fastener can be maintained. Similarly, when the retaining member is screwed into two screw holes, the mounting orientation relative to the central protrusion of the retaining member can be maintained, and if, for example, the second mounting device has a rotation restricting part that contacts the retaining member to restrict rotation, the rotation restriction can be performed at the correct position.

[0025] In the lighting device of the present invention, the first mounting tool has a mounting portion which has the first wiring groove formed therein and is attached to the mounting portion of the lighting body, and a spike portion which extends downward from the mounting portion and can be inserted into the ground, and the wiring fastener for fixing the wiring is fixed to the mounting portion of the lighting body, and the mounting portion may have an internal space between itself and the base portion in which the wiring passed through the first wiring groove and the wiring fastener are arranged. With this configuration, the lighting unit and the first mounting fixture can be used to create a ground-insertion type lighting device.

[0026] In the lighting device of the present invention, the second mounting device comprises a base body and a case body attached to the base body and forming an internal space between itself and the base body in which the wiring, fasteners and retaining members are arranged, the case body having a front wall, a pair of side walls continuous with the front wall and in contact with the base body, and a pair of end walls continuous with the front wall and the pair of side walls and in contact with the base body, The front wall of the case may have a base mounting portion and a mounting projection for which the fastener is attached, and the pair of second wiring grooves may be formed on the pair of case end walls. With this configuration, a wall-mounted lighting device can be constructed in which the base body can be fixed to a wall or the like using the lighting unit and the second mounting device.

[0027] The lighting body of the present invention is the lighting body in the lighting device of the present invention described above. With this configuration, a lighting unit capable of exhibiting the effects of the lighting device of the present invention described above can be constructed. [Explanation of symbols]
