Description

The present invention relates to a lighting device for exterior use.

Conventionally, there is known an exterior lighting device that is installed in any outdoor location such as a garden (see Patent Document 1). The exterior lighting device includes a lighting main body (lighting main body) and an installation tool to which the lighting main body is attached. The lighting main body includes 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 includes an attachment part that is fitted and fixed to the fitting and fixing part, and a spike part that extends downward from the attachment part. The lamp is connected to wiring inside the fitting and fixing part, and this wiring is pulled out to the outside from a wiring conductor formed in the attachment 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.

JP 2016-115590 A

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 reinserting the spike part into the ground, so this exterior lighting device does not itself have a structure that allows the light fixture to be rotated left and right.
Incidentally, there may be cases where the lighting body is to be attached using an installation tool that can be installed on, for example, a wall or a pillar of an outdoor structure. In such a case, it is desirable to configure the exterior lighting device itself so that the luminaire can rotate left and right. However, when the exterior lighting device is modified to newly configure a rotating part in order to further enable left and right rotation in the exterior lighting device, the lighting device may become larger in size due to the provision of a configuration for connecting wiring inside the fitting and fixing part or the newly configured rotating part, and there is also a risk of interference between the configured rotating part and the wiring.

The objective of the present invention is to provide a lighting device that can prevent the device from becoming too large and also prevents interference between the rotating part and the wiring.

The lighting device of the present invention comprises a lamp unit from which wiring is pulled out to the outside, a base unit connected to the lamp unit, and a case body having a concave base arrangement part in which the base unit is rotatably arranged and in which the wiring is arranged, the base unit and the base arrangement part constitute a rotating part that allows the lamp unit to rotate, and the case body has an inlet wiring groove through which the wiring that is pulled into the inside of the case body is inserted, an outlet wiring groove through which the wiring that is pulled out from the inside of the case body to the outside is inserted, and a front end of the case body in the insertion direction of the wiring into the case body. The mounting portion is arranged on the side of the inlet wiring groove relative to the rotating portion and is fitted with a swing restriction device that restricts the swing of the wiring, and a mounting protrusion is arranged in the outlet wiring groove relative to the rotating portion in the insertion direction and is fitted with a wiring stopper that fixes the wiring. The restriction position of the wiring whose swing is restricted by the swing restriction device and the fixed position of the wiring fixed by the wiring stopper are located on the opposite side of the base portion relative to the rotating portion in the front-rear direction perpendicular to the insertion direction.

The present invention provides a lighting device that can reduce size and interference between the rotating part and wiring.

[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 with a wiring 2 drawn out to the outside, a die-cast base unit 31 with a connecting part 25 formed to connect the light unit 21 so as to be vertically rotatable about a rotation axis O1 along the X-axis direction, a die-cast case body 61 having a concave base arrangement part 65 in which the base unit 31 is arranged so as to be horizontally rotatable 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 restricting tool 91 which is a metal fitting that restricts the swing of the wiring 2 inside the case body 61, and a tension stopper 95 which 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, the base body 71, the swing restriction device 91 and the 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.

The electric light unit 21 has a light source (not shown) such as an LED that emits light from the front of the main body 22 inside the main body 22, and the wiring 2 is led out to the outdoors from the rear of the main body 22. The electric light unit 21 is waterproofed by itself, and therefore there is no need to waterproof the connecting part 25, the base part 31, or the installation tool 60.
As shown in Figures 7 (A) to (C), the lighting 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 is 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 part 222 has a rear cylinder part 224 having a notch 223 in which the bearing part 23 is disposed, and a rear bottom part 225 that closes the rear cylinder part 224 on the front part 221 side and through which the wiring 2 is drawn out. The rear bottom part 225 has a water puddle part 226 on its bottom surface that is close to the front part 221 side. The bottom surface 230 of the notch 223 is disposed in a position flush with the bottom surface 231 of the water puddle part 226, so that rainwater and the like can be smoothly drained from the notch 223. In this embodiment, the bearing part 23 has a recess 232 formed at a position opposite the bottom surface 230 of the notch 223, improving drainage, but the configuration of the recess 232 may be omitted if sufficient drainage can be ensured.

The base portion 31 has a base main body portion 32 having a circular outer periphery and a substantially cylindrical inner cylindrical portion 33 that protrudes downward from the center of the base main body portion 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 lamp portion 21 to form a hinge mechanism.
The rotation axis O1 of the bearing parts 23, 26 is aligned along the X-axis direction, and therefore the light part 21 is rotatable (pivotable) up and down about the rotation axis O1 relative to the connecting part 25. The up and down lighting direction of the light part 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 at a vertical position flush with the lower edge of the outer cylindrical portion 322. The inner cylindrical portion 33 has a central protrusion 331 having a circular outer periphery that 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 in which an O-ring 113, described later, can be disposed is formed between the central protrusion 331 and the outer peripheral edge 332.
The lower surface 34 of the central protrusion 331 of the base 31 is provided with a mounting portion 35 to which a retaining member 100 can be mounted to prevent the base 31 from coming off the base arrangement portion 65, and two positioning protrusions 37 to 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 having a diameter larger than the central protrusion 331 and a restricted portion 102 protruding radially from the disk-shaped main body 101. The disk-shaped main body 101 is provided with a hole 103 through which two screws 3 that screw into the two screw holes 353 are inserted, and two positioned holes 104 into which the two positioning protrusions 37 are inserted and positioned. 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 around the rotation axis O2 together with the lighting body 20, and when the retaining member 100 rotates a predetermined amount, the restricted portion 102 comes into contact with the rotation restricting portion 674, 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 in which the inner periphery of the central protrusion 331 bulges 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. The pair of bulging portions 351 have two screw holes 353 formed along the X-axis direction into which the retaining member 100 is screwed by the 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 31 is provided with an attachment portion 36 disposed at a position on the inner periphery side of the outer cylindrical portion 322 and on the outer periphery side of 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 32 at a position on one side in the X-axis direction relative to the inner cylindrical portion 33, and a continuous attachment portion 362 that connects the outer cylindrical portion 322 and the inner cylindrical portion 33 of the base main body 32 at a position on the other side in the X-axis direction relative to the inner cylindrical portion 33. The continuous attachment portions 361 and 362 each have a screw hole 363 that can be used to screw in another installation tool having a spike portion, which will be described later. 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.

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 case front wall 62 is formed in a generally rectangular plate shape and has the above-mentioned pedestal arrangement portion 65, an attachment portion 66 to which the swing restricting device 91 is attached, and an attachment protrusion 67 to which the tension stopper 95 is attached. The pedestal arrangement portion 65, the attachment portion 66, and the attachment protrusion 67 are each disposed inside the case body 61.
The base arrangement portion 65 is formed in a concave shape with a peripheral wall 651 continuing to the case front wall 62 and a bottom wall 652 continuing to 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 portion 32. In addition, a pair of drainage holes 653 that open on the surface of the case front wall 62 are formed in the peripheral wall 651 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, one of the drainage holes 653 is arranged on the side of the inlet wiring groove 68 of the peripheral wall 651, and the other drainage hole 653 is arranged on the side of the outlet wiring groove 68 of the peripheral wall 651. The bottom wall 652 is formed with a circular hole 673 in which the central protrusion 331 of the inner cylindrical portion 33 is arranged so as to be rotatable left and right, and a rotation restriction portion 674 that protrudes toward the base body 71 side. The hole 673 has a diameter dimension smaller than the diameter dimension of the outer circumferential edge portion 332 of the inner cylindrical portion 33. The rotation restricting portion 674 is disposed at a position where the restricted portion 102 of the stop member 100 can come into contact therewith.
The mounting portion 66 is disposed at a position above (on one side of) the base arrangement 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 by two screws 5.
The mounting protrusion 67 is disposed at a position below (the other side) the position of the pedestal 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 a 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 place by two screws 6 that engage with the screw holes 675.
A pair of wiring grooves 68 are formed in each of the pair of 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 (incoming wiring groove) is configured to allow the wiring 2 drawn into the inside of the case body 61 to pass therethrough, and is formed larger in the front-rear and left-right directions than the lower wiring groove 68 (outgoing wiring groove), forming a gap that allows the wiring 2 to swing with the up-down and left-right rotation (swing) of the light unit 21. The bottom of the incoming wiring groove 68 and the screw fastening position of the swing restricting device 91 to the mounting portion 66 are approximately at 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 in the Z-axis direction.
The exit-side wire-passing groove 68 is configured so that the wires 2 drawn from the inside of the case body 61 to the outside can be inserted therethrough. Here, the base portion 31 and the base arrangement portion 65 configure the rotating portion 10 that allows the lamp portion 21 to rotate left and right about a rotation axis O2 along the Z-axis direction, the mounting portion 66 is disposed on the entrance-side wire-passing groove 68 side relative to the rotating portion 10 in the Y-axis direction, and the mounting protrusion 67 is disposed on the exit-side wire-passing groove 68 side relative to the rotating portion 10 in the Y-axis direction.
A pair of screws 7, which will be described later, are arranged on both the left and right sides of an output wiring groove 68 formed in the lower case end wall 64, and this lower case end wall 64 is screwed to a base body 71 by the screws 7. When this 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 restricting device 91, the tension stopper 95, the pull-out prevention member 100, etc. are arranged.

2 and 4 to 6, the swing restriction device 91 is a metal fitting having a substantially rectangular substrate portion 911 along the X-axis direction, a pair of engagement pieces 912 extending from both side edges of the substrate portion 911 along the Y-axis direction toward the base body 71 in the Z-axis direction, and a swing restriction piece 913 extending from the lower edge of the substrate portion 911 along the X-axis direction toward the base body 71 in the Z-axis direction 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 restriction piece 913 has a wiring restriction surface 914 that is semicircular in plan view as shown in FIG. 6, and the wiring restriction surface 914 abuts against the wiring 2 at its bottom portion 914A in the Z-axis direction to restrict the swing of the wiring 2 toward the front side (the electric light unit 21 side). In addition, the wiring restriction surface 914 is disposed at a distance from the wiring 2 in the X-axis direction, thereby allowing the wiring 2 to swing in the X-axis direction by the distance, and restricts the swing in the X-axis direction by more than the distance by contacting the wiring 2. Note that the swing restriction device 91 shown in FIG. 2 is shown closer to the base body 71 than the wiring 2 for convenience of explanation, but in reality, it is attached to the mounting part 66 before the wiring 2 is placed as shown in FIG. 4. In addition, 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 wiring 2 with the pair of clamping pieces 41, the wiring 2 is fixed so that it does not move even if the wiring 2 is pulled by being stepped on, for example.

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 fixing to a wall, a pillar, etc. with screws, etc. 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 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 parts 732 that extend from the upper edge of the plate-shaped main body 731 toward the case front wall 62 and engage with the engagement piece part 912 of the rocking motion restricting device 91, and a pair of fixing parts 733 that extend from the lower edge of the plate-shaped main body 731 toward the case front wall 62 and fix the case body 61 with screws 7 as fixing devices, and the fixing parts 733 are arranged at a position lower than the engagement parts 732. A large diameter hole 734 is formed in the approximate center of the plate-shaped main body 731, which is large enough to allow the wiring 2 to be inserted therethrough. The pair of engagement parts 732 are arranged opposite each other with a gap in the X-axis direction. The engagement parts 732 are formed with engagement holes 735 that engage with the engagement parts 912A of the engagement piece part 912 of the rocking motion restricting device 91. The pair of fixing parts 733 are each formed with a screw hole 736 into which the screw 7 (see FIG. 8) is screwed.
In this base body 71, the case body 61 in which the lighting body 20 is installed can be temporarily positioned by hanging it on the base body 71 by engaging the engaging piece portion 912 of the rocking motion control device 91 with the engaging portion 732, 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.

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 around the rotation axis O2 with respect to the base arrangement part 65 of the case body 61, the central protrusion 331 is arranged in a hole 673 of the bottom wall 652, and the retaining member 100 is attached to the mounting part 35 by screwing the screw 3 into the screw hole 353. An annular resin plate 111 is arranged between the outer peripheral edge part 332 of the inner cylindrical part 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 part 333. The resin plate 111 reduces the sliding resistance compared to when the die-cast outer peripheral edge part 332 and the die-cast bottom wall 652 directly slide against each other. The resin plate 112 reduces the sliding resistance compared to when the die-cast bottom wall 652 and the metal retaining member 100 slide directly against each other. The O-ring 113 elastically deforms as the screw 3 is threaded into the screw hole 353, and the elastic force generated at this time is used to appropriately increase the sliding resistance between the pedestal portion 31 and the pedestal arrangement portion 65.
In the lighting device 1 of this embodiment, the base portion 31, the base mounting portion 65 and the anti-pullout member 100 are assembled using a screw 3, resin plates 111, 112 and an O-ring 113 to form the aforementioned rotating portion 10 which enables the lighting body 20 to rotate left and right relative to the installation tool 60.

The wiring 2 is arranged in a position overlapping the rotating part 10 in the Z-axis direction. The restricting position P1 of the wiring 2, where the swinging is restricted by the swing restricting device 91, particularly the forward swinging by the bottom part 914A, and the fixing position P2 of the wiring 2, where the wiring 2 is fixed by the tension stopper 95, are arranged on the base body 71 side in the Z-axis direction with respect to the rotating part 10. Therefore, the rotating part 10 is arranged on the electric light part 21 side in the Z-axis direction with respect to the wiring 2, whose swinging is restricted by the swing restricting device 91 and which is fixed by the tension stopper 95, thereby suppressing interference of the wiring 2 with the rotating part 10. It is preferable to form a gap of about 1 mm between the wiring 2 and the rotating part 10.

[Modification]
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 as long as the light unit 21 can be configured to be rotatable up, down, left, and right within a sufficient range, it may be configured without such a distance.
In the above embodiment, the rocking restriction member 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 by 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. As long as the wiring stopper can fix the wiring 2 so that the light unit 21 does not swing even when the wiring 2 is pulled, it does not have to be configured like the tension stopper 95 having a pair of clamping pieces 41.
In the above embodiment, the tension stopper 95 and the anti-pullout 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 the tension stopper 95 and the anti-pullout member 100 may be screwed into three or more screw holes, or may be screwed into one screw hole as long as the tension stopper 95 and the anti-pullout member 100 can be secured in a functional manner.
In the embodiment, the wire 2 inserted into the inlet wire passing groove 68 is inserted into the outlet wire passing groove 68 and passed through the case body 61, but this is not limiting, and for example, when the wall or pillar on which the installation tool 60 is to be installed is hollow, the wire 2 may not be inserted into the outlet wire passing groove 68, but may be 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 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, the present invention is not limited to this, and the lighting device 1 may be installed on the floor or ceiling of an outdoor structure having a floor or ceiling. For example, when the lighting device 1 is installed on a ceiling surface as shown in FIG. 8, water such as rainwater that penetrates into the inside of the case body 61 from the wiring groove 68 is drained through the inside of the case body 61 through the water drain hole 653 as shown by the arrow 8. When installed in this way, 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-mentioned embodiment, and each direction is, for example, as shown in FIG. 8.
The lighting body 20 in the above embodiment can be used as it is for other installation tools different from the installation tool 60. For example, when the lighting body 20 is used for another plug-in type installation tool having a spike part to be inserted into the ground, the other installation tool can be attached to the mounting part 36 of the base part 31 by screwing or the like instead of the installation tool 60 to configure another type of lighting device. In this case, when the wiring 2 is passed through the other installation tool, a tension stopper 95 for fixing the wiring 2 may be screwed to the mounting part 35 of the base part instead of the pull-out prevention member 100. Note that when the tension stopper 95 is attached to the mounting part 35, it is preferable that the positioning protrusion 37 is disposed at a position away from the wiring 2 passing through the inside of the case body 61 and at a position where the tension stopper 95 can be positioned and guided to a predetermined position.

In the above embodiment, one drainage hole 653 is disposed on the side of the inlet wire passing groove 68, and the other drainage hole 653 is disposed on the side of the outlet wire passing groove 68, but this is not limited thereto, and as long as sufficient drainage performance can be obtained, for example, a pair of drainage holes 653 disposed 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 arrangement portion 65, this is not limited thereto, and as long as sufficient drainage performance can be obtained, for example, only one drainage hole may be formed, 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 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 includes the swing restricting tool 91 and the tension stopper 95, but these configurations may be omitted if, for example, there is no problem in terms of the layout and performance of the wiring 2 of the lighting device 1 without these configurations. In this case, the configurations of the mounting portion 66 and the mounting protrusion 67 may also be omitted.

[Summary of the invention]
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 forming 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 a casing having a casing having a recessed base arrangement portion in which the wiring is rotatably arranged and in which the wiring is arranged, the casing having an inlet wiring groove through which the wiring drawn into the inside of the case body is inserted, and an outlet wiring groove through which the wiring drawn out from the inside of the case body is inserted in a direction in which the wiring is inserted into the case body. The wiring is provided with an attachment portion on the incoming wiring groove side relative to the rotating portion and on which a swing control device is attached that controls the swing of the wiring, and an attachment protrusion on which a wiring stopper is attached that is arranged in the outgoing wiring groove relative to the rotating portion in the insertion direction and on which a wiring stopper is attached that fixes the wiring, and the restriction position of the wiring whose swing is controlled by the swing control device and the fixing position of the wiring fixed by the wiring stopper are located on the opposite side of the base portion side relative to the rotating portion in the front-to-back direction perpendicular to the insertion direction.
According to the lighting device of the present invention, since the wiring drawn from the electric light unit to the outside is arranged inside the case body, it is possible to eliminate the need to provide a connection part for the wiring inside the case body or to waterproof this part, and it is possible to suppress the increase in size of the lighting device. In addition, since the restricting position and the fixing position of the wiring are arranged on the opposite side of the rotating part from the base part side in the front-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.

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 fore-and-aft direction and the swing in a width direction perpendicular to the insertion direction and the fore-and-aft direction, and the wiring control surface may be positioned at a distance from the wiring in the width direction.
According to this configuration, the swing restricting device restricts the swing of the wiring toward the light unit with its wiring restricting surface, thereby reducing the risk of the wiring interfering with the rotating unit, and since the wiring restricting surface is disposed at a distance from the wiring in the width direction, swing of the wiring in the width direction (left and right direction) is permitted only by the distance and swinging of the wiring beyond the distance can be restricted. Also, when the case body is attached to an outdoor structure such as a wall or a pillar, the swing of the wiring is restricted by the wiring restricting surface, thereby preventing the wiring from being disposed in an unintended position, making it difficult to attach the case body.

In the lighting device of the present invention, a base body to which the case body is attached is provided, and the rocking motion restricting device has an engagement piece portion protruding toward the base body, and the base body may have an engagement portion with which the engagement piece portion engages, and a fixing portion formed at a position below the engagement portion and to which the case body is fixed by a fixing device.
According to this configuration, first, the engaging piece of the rocking restricting device is engaged with the engaging part of the base body, so that the case body to which the rocking restricting device is attached can 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 case body can be attached to the base body more easily by the provisional positioning compared to, for example, a case in which the restricting piece of the rocking restricting device and the like are not engaged with the base body side and the case body is attached to the base body only with the fixing device, and workability can be improved.

In addition, the lighting device of the present invention comprises a lighting body and an installation tool to which the lighting body is attached, the lighting body having an electric light section from which wiring is pulled out to the outside and a base section connected to the electric light section, the installation tool having a case body having a concave base placement section on the front wall of the case in which the base section is rotatably positioned and in which the wiring is placed, the base section and the base placement section form a rotating section that allows the electric light section to be rotated, the case body has a wiring 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 is formed with 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 a ceiling surface or the like of an outdoor structure, the lighting device in which the lighting main body together with the base portion can be rotated can be installed on the ceiling surface or the like.
In addition, although water may enter the case through the wiring groove due to the influence of rain and wind, when the lighting device is installed on the ceiling, the water inside the case can be drained through the drainage hole that is opened in the front wall of the case facing downward. This makes it possible to prevent water from accumulating inside the installation tool that is installed on the ceiling of an outdoor structure.
The lighting device can be installed not only on the ceiling surface, but also on outdoor walls, pillars, etc.

In the lighting device of the present invention, the front wall of the case is formed with a mounting portion to which a swing-restricting device that restricts the swinging of the wiring inside the case body is attached, and a mounting protrusion to which a wiring fastener that fixes the wiring inside the case body is attached, and the mounting portion and the mounting protrusion may protrude from the front wall of the case on the side opposite to the lighting body.
According to this configuration, even if the lighting device is installed on the ceiling surface of an outdoor structure, by attaching the swing restricting device to the mounting part and the wiring fastener to the mounting protrusion, it is possible to suppress the swing of the wiring caused by the rotation of the light unit and the unintended swing of the light unit caused by the wiring being pulled. Furthermore, since the mounting part and the mounting protrusion protrude from the front wall of the case toward the base body, the swing restricting device and the 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.

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 water drainage holes are formed in the peripheral wall of the base arrangement portion, one of the pair of water drainage holes is arranged 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 water drainage holes is arranged 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, when 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 when 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.
In addition, when the lighting device is installed on an outdoor wall or pillar, water that seeps in through the wiring groove formed in one (upper) of the pair of case end walls can be drained through the wiring 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 from the above-mentioned mounting orientation, water can be drained through the wiring groove in roughly the same manner.

In the lighting device of the present invention, the light 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 tube portion having a notch in which the bearing portion is located, and a rear bottom portion that covers the rear tube portion on the front portion side and from which the wiring is pulled 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 either 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 direction of the light unit faces downward, even if rainwater or the like gets into the puddle on the back side of the light, 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 side and entering the light unit from this part.
