Description

[Technical Field]

[0001] The present invention relates to a lighting device for exterior use. [Background technology]

[0002] Conventionally, there has been known an exterior lighting device that can be installed in any outdoor location, such as a garden (see Patent Document 1). The exterior lighting device comprises a lighting main body (lighting main body) and an installation tool to which the lighting main body is attached. The lighting main body comprises a lamp and a fitting and fixing part to which the lamp is connected so that it can rotate up and down. The installation tool has a mounting part that is fitted and fixed to the fitting and fixing part, and a spike part that extends downward from the mounting part. The lamp is connected to wiring inside the fitting and fixing part, and this wiring is pulled out to the outside through a wiring conduction path formed in the mounting part. This exterior lighting device is installed by inserting the spike part into the ground, and the left-right orientation of the lamp can be changed by inserting the spike part back into the ground.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-115590 Summary of the Invention [Problem to be solved by the invention]

[0004] The exterior lighting device described in Patent Document 1 is a plug-in type lighting device in which the spike part is inserted into the ground, and as mentioned above, the left-right orientation of the light part can be changed by inserting the spike part back into the ground, so the exterior lighting device itself does not have a structure that allows the light fixture to be rotated left and right. However, there may be cases where a lighting unit is to be attached using an installation tool that can be installed on the ceiling of an outdoor structure, for example. In such cases, since the spike cannot be reinserted into the ground as described above, it is desirable to configure the exterior lighting device itself so that the lighting fixture can rotate left and right. Furthermore, when an exterior lighting device is installed on the ceiling of an outdoor structure, the exterior lighting device installed on the ceiling is exposed to rain and wind, and there is a risk that water will seep in and accumulate inside the installation tool installed on the ceiling.

[0005] An object of the present invention is to provide a lighting device that can prevent water from accumulating inside an installation tool that is installed on the ceiling surface of an outdoor structure. [Means for solving the problem]

[0006] The lighting device of the present invention comprises a lighting body and an installation tool to which the lighting body is attached, wherein the lighting body has a light section from which wiring is pulled out to the outside and a base section connected to the light section, the installation tool has a case body having a concave base placement section on the front wall of the case in which the base section is rotatably placed and in which the wiring is placed, the base section and the base placement section form a rotating section that allows the lighting section to rotate, the case body has a wiring passage groove through which the wiring is inserted, and the base placement section has a peripheral wall that is continuous with the front wall of the case and a bottom wall that is continuous with the peripheral wall, and the peripheral wall has at least one drainage hole that opens into the front wall of the case. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a lighting device that can prevent water from accumulating inside an installation tool that is installed on the ceiling surface of an outdoor structure. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] [Configuration of this embodiment] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 and 2, the lighting device 1 according to this embodiment is a wall-mounted lighting device for exterior use that is fixed to a wall or a pillar around a building. The lighting device 1 includes a light unit 21 from which a wiring 2 is drawn to the outside, a die-cast base 31 formed with a connecting portion 25 to which the light unit 21 is connected so as to be rotatable up and down about a rotation axis O1 along the X-axis direction, a die-cast case body 61 having a recessed base arrangement portion 65 in which the base unit 31 is rotatable left and right about a rotation axis O2 (see FIG. 4) along the Z-axis direction and in which the wiring 2 is arranged, a base body 71 to which the case body 61 is attached, a swing restrictor 91 that is a metal fitting that restricts the swing of the wiring 2 inside the case body 61, and a tension stopper 95 that is a metal fitting that serves as a wiring stopper that fixes the wiring 2 inside the case body 61. The light unit 21 and the base unit 31 including the connecting unit 25 constitute the lighting body 20, and the case body 61, base body 71, swing control device 91 and tension stopper 95 constitute the installation tool 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-rear direction of the lighting device 1 is defined as the Z-axis direction. The X, Y, and Z axis directions are perpendicular to each other.

[0010] The light unit 21 has a light source (not shown) such as an LED inside the main body 22 that emits light from the front of the main body 22, and wiring 2 is drawn outside from the back of the main body 22. The light unit 21 itself is waterproofed, and therefore there is no need to waterproof the connecting part 25, base part 31, or installation tool 60. As shown in Figures 7(A) to (C), the light unit 21 has a main body 22 having a front portion 221 and a back portion 222, and the aforementioned bearing portion 23 that is attached to the main body 22 and connected to the base portion 31 so as to be rotatable up and down, and the bearing portion 23 is connected to the connecting portion 25. The rear surface portion 222 has a rear surface cylindrical portion 224 having a notch 223 in which the bearing portion 23 is disposed, and a rear surface bottom portion 225 that closes the rear surface cylindrical portion 224 on the front surface portion 221 side and through which the wiring 2 is drawn out. The rear surface bottom portion 225 has a water reservoir portion 226 on its bottom surface that is close to the front surface portion 221 side. A bottom surface 230 of the notch 223 is disposed in a position flush with a 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, a recess 232 is formed in the bearing portion 23 at a position opposite the bottom surface 230 of the notch 223, thereby improving drainage, but the recess 232 may be omitted if sufficient drainage can be ensured.

[0011] The base 31 has a base main body 32 having a circular outer periphery and an inner cylindrical portion 33 having a substantially cylindrical shape that protrudes downward from the center of the base main body 32 . As shown in Figures 3 and 4, the base main body 32 has a disk-shaped top plate 321 and a cylindrical outer cylindrical portion 322 extending downward from the periphery of the top plate 321, and the outer periphery of the outer cylindrical portion 322 is circular and slightly inclined so as to approach the inner cylindrical portion 33 as it extends downward. The top plate 321 is formed with a bearing portion 26 (see FIG. 4) which is an upward extension of the connecting portion 25 described above, and is connected to the bearing portion 23 of the light portion 21 to form a hinge mechanism. The rotation axis O1 of the bearings 23 and 26 is aligned along the X-axis direction, and therefore the light unit 21 is rotatable (swivelable) up and down around the rotation axis O1 relative to the connecting unit 25. The up and down lighting direction of the light unit 21 is adjusted by this up and down 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 disposed in a vertical position where it is flush with the lower edge of the outer cylindrical portion 322. The inner cylindrical portion 33 has a central protrusion 331 that has a circular outer periphery and protrudes further downward from the center, and this central protrusion 331 is cylindrical and protrudes downward further than the outer cylindrical portion 322. An annular groove 333 is formed between the central protrusion 331 and the outer peripheral edge 332, in which an O-ring 113, described later, can be placed. The underside 34 of the central protrusion 331 of the base 31 is formed with a mounting portion 35 to which a retaining member 100 can be attached, which prevents the base 31 from slipping out of the base placement portion 65, and two positioning protrusions 37 that position and guide the retaining member 100 at a predetermined position away from the wiring 2. The retaining member 100 is a metal fitting having a disk-shaped main body 101 with a diameter larger than that of the central protrusion 331 and a restricted portion 102 that protrudes radially from the disk-shaped main body 101. The disk-shaped main body 101 is formed with holes 103 through which two screws 3 that thread into the two screw holes 353 are inserted, and two positioned holes 104 into which the two positioning protrusions 37 are inserted to position the main body. The diameter of the disk-shaped main body 101 is larger than the diameter of the hole 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 a predetermined amount, the restricted portion 102 abuts against the rotation restricting portion 674, restricting left and right rotation of the entire lighting body 20 beyond the predetermined amount. The mounting portion 35 has a pair of bulging portions 351 formed by the inner periphery of the central protrusion 331 bulging toward the center. The pair of bulging portions 351 face each other in the X-axis direction and are continuous with each other by a continuous portion 352. Two screw holes 353, into which the retaining member 100 is fastened with screws 3, are formed in the pair of bulging portions 351 along the X-axis direction. 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 is formed with an attachment portion 36 that is located at a position more inward than the outer cylindrical portion 322 and more outward than the inner cylindrical portion 33. The attachment portion 36 has a continuous attachment portion 361 that connects the outer cylindrical portion 322 and the inner cylindrical portion 33 of the base main body portion 32 at a position on one side of the inner cylindrical portion 33 in the X-axis direction, and a continuous attachment portion 362 that connects the outer cylindrical portion 322 and the inner cylindrical portion 33 of the base main body portion 32 at a position on the other side of the inner cylindrical portion 33 in the X-axis direction. Screw holes 363 that can be used to screw in other installation tools having spikes, which will be described later, are formed in the continuous attachment portions 361 and 362. Note that the attachment portion 36 is not used when attaching the lighting body to the installation tool 60, but is used when attaching the lighting body 20 to another installation tool, 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. Case front wall 62 is formed in a generally rectangular plate shape and has the aforementioned pedestal placement portion 65, a mounting portion 66 to which swing restrictor 91 is attached, and a mounting protrusion 67 to which tension stopper 95 is attached. Pedestal placement portion 65, mounting portion 66, and mounting protrusion 67 are each disposed inside case body 61. The base mounting portion 65 is formed in a concave shape and has a peripheral wall 651 continuous with the case front wall 62 and a bottom wall 652 continuous with the peripheral wall 651. The peripheral wall 651 has an inner peripheral surface formed in a circular shape corresponding to the outer cylindrical portion 322 of the base main body 32. The peripheral wall 651 is also formed with a pair of drainage holes 653 that open on the surface of the case front wall 62 and extend from the surface of the case front wall 62 to the bottom wall 652. The pair of drainage holes 653 are arranged opposite each other in the Y-axis direction, with one drainage hole 653 arranged on the peripheral wall 651 side facing the inlet wire passing groove 68, and the other drainage hole 653 arranged on the peripheral wall 651 side facing the outlet wire passing groove 68. The bottom wall 652 is formed with a circular hole 673 through which the central protrusion 331 of the inner cylindrical portion 33 is arranged so as 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 disposed at a position where the restricted portion 102 of the retaining member 100 can come into contact. The mounting portion 66 is disposed at a position above (on one side of) the base placement portion 65, and is formed to protrude from the case front wall 62 toward the base body 71. A swing restricting device 91 is fastened to the mounting portion 66 with two screws 5. The mounting protrusion 67 is disposed at a position below (the other side of) the position of the base arrangement portion 65 and at approximately the center of the case body 61 in the X-axis direction, and is formed to protrude from the case front wall 62 toward the base body 71, with its top surface being disposed closer to the base body 71 in the Z-axis direction than the rotating portion 10, which will be described later. Two screw holes 675 are formed in the mounting protrusion 67, approximately similar to the mounting portion 35, and a tension stopper 95 is screwed in by two screws 6 that thread into the screw holes 675. A pair of wire-passing grooves 68 are formed in each of the pair of case end walls 64, and the pair of wire-passing grooves 68 are arranged opposite each other in the Y-axis direction. The upper wire-passing groove 68 (incoming wire-passing groove) is configured to allow the wire 2 drawn into the interior of the case body 61 to pass therethrough, and is formed larger in the front-to-back and left-to-right directions than the lower wire-passing groove 68 (outgoing wire-passing groove), forming a gap that allows the wire 2 to swing in accordance with the up-down and left-to-right rotation (swiveling) of the light unit 21. The bottom of the incoming wire-passing groove 68 and the position where the swing restrictor 91 is screwed to the mounting portion 66 are approximately in the same position in the Z-axis direction, and are located further away from the base body 71 in the Z-axis direction than the position of the bottom wall 652 of the pedestal arrangement portion 65. The outlet-side wire-passing groove 68 is configured so that the wires 2 that are drawn from the inside to the outside of the case body 61 can be inserted therethrough. Here, the base portion 31 and the base arrangement portion 65 form a rotating portion 10 that enables the light unit 21 to rotate left and right about a rotation axis O2 along the Z-axis direction, the mounting portion 66 is arranged on the inlet-side wire-passing groove 68 side of the rotating portion 10 in the Y-axis direction, and the mounting protrusion 67 is arranged on the outlet-side wire-passing groove 68 side of the rotating portion 10 in the Y-axis direction. A pair of screws 7, which will be described later, are arranged on the lower case end wall 64 at positions on both the left and right sides of an outlet wiring groove 68 formed in the lower case end wall 64, and the lower case end wall 64 is fastened to the base body 71 by the screws 7. When the case body 61 is attached to the base body 71, an internal space is formed between the case body 61 and the base body 71 in which the wiring 2, the swing restrictor 91, the tension stopper 95, the retaining member 100, etc. are placed.

[0013] 2 and 4 to 6, the swing restricting device 91 is a metal fitting having a substantially rectangular base plate 911 along the X-axis direction, a pair of engagement pieces 912 extending in the Z-axis direction from both side edges of the base plate 911 along the Y-axis direction toward the base body 71, and a swing restricting piece 913 extending in the Z-axis direction from a lower edge of the base plate 911 along the X-axis direction toward the base body 71 at a position between the pair of engagement pieces 912. The engagement piece 912 has an engagement portion 912A that protrudes downward, and the swing restricting piece 913 has a wiring restricting surface 914 that is semicircular in plan view as shown in FIG. 6, and the wiring restricting surface 914 abuts against the wiring 2 at a bottom portion 914A in the Z-axis direction, thereby restricting the swing of the wiring 2 forward (toward the lamp unit 21). Furthermore, by being disposed at a distance from the wire 2 in the X-axis direction, the wire restricting surface 914 allows the wire 2 to swing in the X-axis direction by the distance, and by abutting against the wire 2 when the wire 2 swings in the X-axis direction by more than the distance, the wire restricting surface 914 restricts the swing of the wire 2 by more than the distance. Note that, for convenience of explanation, the swing restricting device 91 shown in FIG. 2 is shown closer to the base body 71 than the wire 2, but in reality, it is attached to the attachment portion 66 before the wire 2 is placed as shown in FIG. 4 and the like. Furthermore, the tension stopper 95 is a metal fitting having a pair of clamping pieces 41 facing each other in the X-axis direction, and by clamping the wire 2 between the pair of clamping pieces 41, the wire 2 is fixed so that it does not move even if it is pulled, for example, by being stepped on.

[0014] The base body 71 is made of a metal plate material that is fixed to a wall, a pillar, etc. with fasteners such as bolts and nuts. A plurality of holes 74 are formed in the base body 71 for fastening to the wall, pillar, etc. with screws, etc. A cushion sheet 72 or the like is interposed between the base body 71 and the outdoor structure such as a wall or pillar to prevent damage to the outdoor structure. The base body 71 is a metal fitting having a plate-shaped main body 731, a pair of engagement portions 732 extending from the upper edge of the plate-shaped main body 731 toward the case front wall 62 and engaging with the engagement piece portions 912 of the rocking motion restrictor 91, and a pair of fixing portions 733 extending from the lower edge of the plate-shaped main body 731 toward the case front wall 62 and fixing the case body 61 with screws 7 as fixing devices, the fixing portions 733 being positioned lower than the engagement portions 732. A large-diameter hole 734 is formed in the approximate center of the plate-shaped main body 731, large enough to allow the wiring 2 to pass therethrough. The pair of engagement portions 732 are positioned opposite each other with a gap in the X-axis direction. The engagement portions 732 are formed with engagement holes 735 into which the engagement portions 912A of the engagement piece portions 912 of the rocking motion restrictor 91 engage. The pair of fixing portions 733 are each formed with a screw hole 736 into which a screw 7 (see FIG. 8) is threadedly engaged. In this base body 71, by engaging the engagement piece portion 912 of the swing limiting device 91 with the engagement portion 732, the case body 61 on which the lighting main body 20 is installed can be temporarily positioned by hanging it on the base body 71, and in this temporarily positioned state, the lower case end wall 64 can be screwed to the fixing portion 733 with the screw 7, thereby attaching the case body 61 to the base body 71.

[0015] The mounting structure of the lighting body 20 to the installation tool 60 is as follows. The base 31 of the lighting body 20 is arranged to be rotatable left and right about a rotation axis O2 relative to the base arrangement portion 65 of the case body 61, the central protrusion 331 is arranged in a hole 673 in the bottom wall 652, and the retaining member 100 is attached to the mounting portion 35 by threading a screw 3 into the screw hole 353. An annular resin plate 111 is arranged between the outer circumferential edge portion 332 of the inner cylindrical portion 33 and the bottom wall 652, a disk-shaped resin plate 112 is arranged between the central protrusion 331 and the retaining member 100, and an elastically deformable rubber O-ring 113 is arranged in the annular groove 333. The resin plate 111 reduces sliding resistance compared to when the die-cast outer circumferential edge portion 332 and the die-cast bottom wall 652 slide directly against each other. Resin plate 112 reduces sliding resistance compared to when die-cast bottom wall 652 slides directly against metal retaining member 100. O-ring 113 undergoes elastic deformation as screw 3 is threaded into screw hole 353, and the elastic force generated at this time is used to appropriately increase the sliding resistance between pedestal portion 31 and pedestal placement portion 65. In the lighting device 1 of this embodiment, the base portion 31, the base placement portion 65 and the anti-pullout member 100 are assembled using screws 3, resin plates 111, 112 and an O-ring 113 to form the aforementioned rotating portion 10 that enables the lighting body 20 to rotate left and right relative to the installation tool 60.

[0016] The wiring 2 is disposed in a position overlapping the rotating unit 10 in the Z-axis direction. A restriction position P1 of the wiring 2, where the swing restriction device 91 restricts swing, particularly forward swing, by the bottom 914A, and a fixing position P2 of the wiring 2, where the wiring 2 is fixed by the tension stopper 95, are disposed on the base body 71 side in the Z-axis direction relative to the rotating unit 10. Therefore, the rotating unit 10 is disposed on the lamp unit 21 side in the Z-axis direction relative to the wiring 2, whose swing restriction is restricted by the swing restriction device 91 and which is fixed by the tension stopper 95, thereby suppressing interference of the wiring 2 with the rotating unit 10. It is preferable to form a gap of about 1 mm between the wiring 2 and the rotating unit 10.

[0017] [Variations] In the above embodiment, the wiring control surface 914 of the swing control device 91 is arranged at a distance from the wiring 2 in the Z-axis direction, but it may be arranged without this distance as long as the light unit 21 can be configured to be rotatable up, down, left, and right within a sufficient range. 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 fixed to the base body 71 with screws. 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, but this is not limited to this. Any wiring stopper that can fix the wiring 2 so that the light unit 21 does not swing even when the wiring 2 is pulled does not have to be configured like the tension stopper 95 that has a pair of clamping pieces 41. In the above embodiment, the tension stop 95 and the retaining member 100 are screwed into the mounting portion 35 and the mounting protrusion 67 by screwing the screws 3 and 6 into two screw holes 353 and 675, respectively, but they may also be configured to be screwed into three or more screw holes, or they may be configured to be screwed into one screw hole as long as the tension stop 95 and the retaining member 100 can be secured in a functional manner. In the above embodiment, the wires 2 inserted into the inlet wire-passing grooves 68 are passed through the outlet wire-passing grooves 68 and then passed through the case body 61, but this is not limiting. For example, if the wall or pillar on which the installation tool 60 is to be installed is hollow, the wires 2 may not be passed through the outlet wire-passing grooves 68, but may be passed through the large diameter hole 734 of the base body 71. In this case, the tension stop 95 may be omitted. In the above embodiment, the wall-mounted lighting device 1 is configured such that the base body 71 is fixed to an outdoor structure such as a wall or a pillar, the swing restrictor 91 is hung on the base body 71, and the lower case end wall 64 can be screwed to the base body 71. However, this is not limited to this, and the lighting device 1 may also be installed on the floor or ceiling of an outdoor structure that has a floor or ceiling. For example, when the lighting device 1 is installed on a ceiling as shown in FIG. 8, water such as rainwater that enters the inside of the case body 61 through the wiring groove 68 passes through the inside of the case body 61 as shown by arrow 8 and is drained through the drain hole 653 described above. When installed in this manner, the X, Y, and Z axis directions are different from those of the lighting device 1 that is hung on a wall or a pillar as in the above-described embodiment, and each direction is as shown in FIG. 8, for example. The lighting body 20 in the above embodiment can be used as is with other installation tools different from the installation tool 60. For example, when using the lighting body 20 with another plug-in type installation tool having spikes that are inserted into the ground, another type of lighting device can be configured by attaching the other installation tool to the mounting portion 36 of the base 31 by screwing or the like instead of the installation tool 60. In this case, when the wire 2 is passed through the other installation tool, a tension stop 95 that secures the wire 2 may be screwed to the mounting portion 35 of the base instead of the retaining member 100. Note that when attaching the tension stop 95 to the mounting portion 35, it is preferable that the positioning protrusion 37 is positioned away from the wire 2 that passes through the inside of the case body 61 and that the tension stop 95 can be positioned and guided to a predetermined position.

[0018] In the above embodiment, one drainage hole 653 is arranged on the inlet-side wire-passing groove 68 side, and the other drainage hole 653 is arranged on the outlet-side wire-passing groove 68 side, but this is not limiting, and as long as sufficient drainage performance can be obtained, for example, a pair of drainage holes 653 arranged opposite each other in the X-axis direction may be provided. Also, while a pair of drainage holes 653 is formed in the peripheral wall 651 of the base placement portion 65, this is not limiting, and for example, only one drainage hole may be formed as long as sufficient drainage performance can be obtained, or, for example, three or more drainage holes may be formed in order to improve drainage performance. In the above embodiment, the drain hole 653 is formed extending from the front wall 62 of the case to the bottom wall 652, but it is not limited to this shape and may be of various other shapes as long as it opens in the front wall 62 of the case and is capable of draining water. In the above embodiment, the installation tool 60 is provided with the swing restricting device 91 and the tension stopper 95, but these components may be omitted if, for example, there is no problem with the routing or performance of the wiring 2 of the lighting device 1 without these components. In this case, the mounting portion 66 and the mounting protrusion 67 may also be omitted.

[0019] [Summary of the invention] The lighting device of the present invention comprises a lighting body and an installation tool to which the lighting body is attached, wherein the lighting body has a light section from which wiring is pulled out to the outside and a base section connected to the light section, the installation tool has a case body having a concave base placement section on the front wall of the case in which the base section is rotatably placed and in which the wiring is placed, the base section and the base placement section form a rotating section that allows the lighting section to rotate, the case body has a wiring passage groove through which the wiring is inserted, and the base placement section has a peripheral wall that is continuous with the front wall of the case and a bottom wall that is continuous with the peripheral wall, and the peripheral wall has at least one drainage hole that opens into the front wall of the case. According to the lighting device of the present invention, by attaching the case body to the ceiling surface or the like of an outdoor structure, the lighting device in which the lighting body can rotate together with the base portion can be installed on the ceiling surface or the like. Furthermore, although water can get into the case through the wiring groove due to wind and rain, when the lighting device is installed on a ceiling, the water inside the case can be drained through the drainage holes in the downward-facing front wall of the case, preventing water from accumulating inside the installation tool when it is installed on the ceiling of an outdoor structure. The lighting device can be installed not only on the ceiling surface but also on an outdoor wall or pillar.

[0020] In the lighting device of the present invention, the front wall of the case is formed with an attachment portion to which a swing-restricting device that restricts the swing of the wiring inside the case body is attached, and an attachment protrusion to which a wiring fastener that fixes the wiring inside the case body is attached, and the attachment portion and the attachment protrusion may protrude from the front wall of the case on the side opposite to the lighting main body side. With this configuration, even when the lighting device is installed on the ceiling surface of an outdoor structure, by attaching the swing limiter to the mounting part and the wiring fastener to the mounting protrusion, it is possible to suppress swing of the wiring due to rotation of the light unit and unintended swing of the light unit due to pulling on the wiring. Furthermore, because the mounting part and the mounting protrusion protrude from the front wall of the case toward the base body, the swing limiter and wiring fastener, which are metal fittings, can be positioned so that they are less likely to get wet when the lighting device is installed on the ceiling surface of an outdoor structure.

[0021] In the lighting device of the present invention, the case body has the case front wall, a pair of case side walls continuous with the case front wall, and a pair of case end walls continuous with the case front wall and the pair of case side walls, the wire passing groove is formed in each of the pair of case end walls, and at least a pair of drainage holes is formed in the peripheral wall of the base arrangement portion, one of the pair of drainage holes is located in a portion of the peripheral wall on the wire passing groove side formed in one of the pair of case end walls, and the other of the pair of drainage holes is located in a portion of the peripheral wall on the wire passing groove side formed in the other of the pair of case end walls. With this configuration, when the lighting device is installed on the ceiling surface of an outdoor structure, if water seeps in through the wiring groove formed in one of the pair of case end walls, it can be quickly drained out through one of the drainage holes located in the part on the wiring groove side, and if water seeps in through the wiring groove formed in the other of the pair of case end walls, it can be quickly drained out through the other drainage hole located in the part on the wiring groove side. Furthermore, when the lighting device is installed on an outdoor wall or pillar, water that seeps in through the wire-passing groove formed in one (upper) of the pair of case end walls can be drained through the wire-passing groove formed in the other (lower) of the pair of case end walls. Note that even if the lighting device is installed upside down on the wall or pillar compared to the above-mentioned installation orientation, water can be drained through the wire-passing groove in roughly the same way.

[0022] 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 located, and a rear bottom portion that closes the rear cylindrical portion on the front portion side and from which the wiring is drawn out, the rear bottom portion has a water puddle portion on its bottom surface that is close to the front portion side, and the bottom surface of the notch may be located in a position flush with the bottom surface of the water puddle portion or in a position closer to the front portion side than the bottom surface of the water puddle portion. With this configuration, when the lighting device is attached to an outdoor structure such as a wall or a pillar so that the light from the lamp unit faces downward, even if rainwater or the like gets into the puddle on the back of the lamp, the rainwater or the like can be smoothly drained from the notch configured as described above. This reduces the risk of rainwater or the like collecting around the wiring pulled out from the back and seeping into the lamp unit through this area.

[0023] The lighting device of the present invention includes a lamp unit from which wiring is drawn out to the outside, a base unit connected to the lamp unit, and a case body having a concave base arrangement portion in which the base unit is rotatably arranged and in which the wiring is arranged, the base unit and the base arrangement portion constituting a rotating portion that allows the lamp unit to rotate, and the case body has an inlet wiring groove through which the wiring drawn into the inside of the case body is inserted, an outlet wiring groove through which the wiring drawn out from the inside of the case body is inserted, and and a mounting protrusion, which is arranged in the outlet wire-passing groove relative to the rotating part in the insertion direction and to which a wiring fastener is attached for fixing the wiring, and which is arranged in the outlet wire-passing groove relative to the rotating part in the insertion direction, and which is arranged in the outlet wire-passing groove relative to the rotating part in the insertion direction and to which a wiring fastener is attached for fixing the wiring, and the fixing position of the wiring whose swing is fixed by the swing fastener and the fixing position of the wiring whose swing is fixed by the wiring fastener are located on the opposite side of the base part side relative to the rotating part in the front-to-rear direction perpendicular to the insertion direction. According to the lighting device of the present invention, since the wiring drawn from the light unit to the outside is arranged inside the case body, it is not necessary to provide a wiring connection part inside the case body or to waterproof this part, and it is possible to suppress an increase in the size of the lighting device. In addition, since the restricting position and fixing position of the wiring are arranged on the opposite side of the rotating part from the base part in the front-to-rear direction, even if the wiring is fixed inside the case body, it is possible to suppress interference of the wiring with the rotating part.

[0024] In the lighting device of the present invention, the swing control device has a wiring control surface that controls the swing of the wiring toward the light unit in the front-to-back direction and the swing in a width direction perpendicular to the insertion direction and the front-to-back direction, and the wiring control surface may be arranged at a distance from the wiring in the width direction. With this configuration, the swing restricting device restricts the swing of the wire toward the light unit with its wire restricting surface, thereby reducing the risk of the wire interfering with the rotating unit, and because the wire restricting surface is arranged at a distance from the wire in the width direction, it allows the wire to swing in the width direction (left and right) by only the distance and restricts swinging beyond the distance. Furthermore, when attaching the case body to an outdoor structure such as a wall or a pillar, restricting the swing of the wire with the wire restricting surface can prevent the wire from being placed in an unintended position, making it difficult to attach the case body.

[0025] In the lighting device of the present invention, the swing-control device may include a base body to which the case body is attached and have an engaging piece portion protruding toward the base body, and the base body may have an engaging portion with which the engaging piece portion engages, and a fixing portion formed at a position below the engaging portion and to which the case body is fixed by a fixing device. According to this configuration, first, the engaging piece of the swing restrictor engages with the engaging part of the base body, thereby enabling the case body with the swing restrictor attached to be provisionally positioned relative to the base body, and then the case body can be permanently fixed to the base body by fixing the case body to the fixing part with the fixing device. By attaching the case body to the base body in this way, the provisional positioning makes it easier to attach the case body to the base body, and workability can be improved, compared to, for example, a case in which the case body is attached to the base body only with the fixing device without engaging the restricting piece of the swing restrictor or the like with the base body side.
