Summary of the Invention

Problems to be Solved by the Invention

[0004] When attaching an external lighting device to a pillar, beam, concrete wall, etc., it is required to draw grid lines on the pillar etc. to set the exact attachment position, and attach the lighting fixture mounting bracket according to these grid lines. In addition, the lighting fixture attached to the lighting fixture mounting bracket is provided with wiring connected to the power supply, and the extending direction of this wiring is determined when the lighting fixture is attached to the fixing bracket. Therefore, if the fixing bracket is not attached to the pillar etc. in the correct orientation, there is a problem that the wiring cannot be extended in the correct direction.

[0005] An object of the present invention is to provide a lighting device that can be easily aligned with the grid lines and can extend the wiring from the electric lighting fixture in the correct direction.

Means for Solving the Problems

[0006] The present invention relates to a lighting device comprising a mounting bracket fixed to an object to be mounted, and a light fixture attached to the mounting bracket, wherein the mounting bracket is characterized by having a pair of first holes formed at positions opposite each other on a plane with respect to a reference position, a pair of second holes formed at positions opposite each other on a plane with respect to the reference position and on a second virtual line perpendicular to a first virtual line connecting the pair of first holes, and a wiring direction indicator portion indicating the wiring direction from which the wiring of the light fixture extends. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a lighting device that can be easily aligned with a marked line and that allows wiring from the light fixture to extend in the correct direction. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] Hereinafter, an embodiment of the present invention, the lighting device 1, will be described based on the drawings. As shown in Figures 1 and 2, the lighting device 1 comprises a light fixture 2 and a mounting bracket 3. The light fixture 2 has a cylindrical body portion 21, a light-transmitting portion 22 attached to one end of the body portion 21, and a cover portion 23 attached to the other end of the body portion 21. The body section 21 is formed from aluminum die-cast or the like, and incorporates a light-emitting unit such as an LED inside. The light-transmitting section 22 is molded from a light-transmitting material such as acrylic resin and is configured to diffuse and emit light from the light-emitting unit to the outside. The light-transmitting portion 22 and the cover portion 23 are formed in a circular shape when viewed from the light-transmitting portion 22 side of the lighting device 1 in a plan view, and their outer surfaces are continuous with the outer surface of the body portion 21. The cover portion 23 is formed in the same cylindrical shape as the body portion 21 and is configured to be able to seal the end opening of the body portion 21. The outer peripheral wall 230 of the cover portion 23 has an opening groove 231 for pulling out the wiring 24 extending from the light-emitting unit and a pair of through holes 232 through which bolts 25 for fixing the cover portion 23 to the mounting bracket 3 are inserted. Furthermore, a pair of ribs 233 are formed on the inner surface of the outer circumferential wall 230 at opposing positions. A connector 241 is provided at the end of the wiring 24 for connecting to other wiring. Furthermore, the direction in which the body portion 21, the light-transmitting portion 22, and the cover portion 23 of the light fixture 2 overlap is the Z-axis direction, the direction perpendicular to the Z-axis direction is the X-axis direction, and the direction in which the wiring 24 extends is the Y-axis direction, and the direction perpendicular to the Z-axis direction and the X-axis direction is the Y-axis direction.

[0010] The mounting bracket 3 comprises a base portion 30 and a connecting portion 40. The base portion 30 is a metal plate formed in the shape of a disc, and the connecting portion 40 is a pair of cut-up pieces cut from the base portion 30. As shown in Figure 3, the base portion 30 has a central hole 31, a pair of first holes 32, a pair of second holes 33, a wiring direction indicator portion 34, an opening 35 connecting the central hole 31 and the second holes 33, and a pair of positioning protrusions 36. The central hole 31 is formed at a reference position which is the center position when the base portion 30 is viewed in a plan view from the Z-axis direction, and is sized to allow the connector 241 of the wiring 24 to be inserted. The reference position, as will be described later, indicates the position corresponding to the intersection of vertical and horizontal lines drawn on the object to be mounted, such as a column to which the mounting bracket 3 is attached, and in this embodiment, it is the planar center position of the base portion 30.

[0011] The pair of first holes 32 are formed at reference positions, that is, positions opposite each other with respect to the central hole 31. The first imaginary line L1 connecting the pair of first holes 32 is a line along the X-axis direction. These first holes 32 are used as peepholes for alignment with the marking lines, and may also be used as screw holes through which screws are inserted to fix the mounting bracket 3 to the object to be attached, such as a column or beam.

[0012] The pair of second holes 33 are located at reference positions, that is, opposite positions with the central hole 31 in between, and a second virtual line L2 connecting the pair of second holes 33 is formed at a position perpendicular to the first virtual line L1. The second virtual line L2 is a line along the Y-axis direction. The second holes 33, like the first holes 32, are used as peepholes for alignment with the marking lines, and may also be used as screw insertion holes through which screws for fixing the mounting bracket 3 to the object to be attached, such as a column or beam, are inserted. The first hole 32 and the second hole 33 are formed on concentric circles centered on a reference position. The second hole 33 is not an independent hole like the first hole 32, but is a notch shape connected to the opening 35 via a connecting portion 331. As mentioned above, a screw used to fix the mounting bracket 3 to the object to be mounted may be inserted through the second hole 33, so the opening width of the connecting portion 331 is set to be smaller than the outer diameter of the screw threads to prevent the screw inserted through the second hole 33 from coming out of the connecting portion 331.

[0013] In this embodiment, the wiring direction indicator 34 is an arrow marking formed between one of the pair of first holes 32 and the center hole 31. The opening 35 is opened when forming the connecting portion 40 by press bending or the like. Since the central hole 31 and the second hole 33 are also continuous through this opening 35, these central hole 31, second hole 33, and opening 35 can be formed by a single press process. That is, the opening 35 is continuously formed from the central hole 31 to the base end portion of the connecting portion 40, and further continuous to the second hole 33 through the communication portion 331. The intersection angle between the third virtual line L3 connecting the center positions in the width direction of the pair of connecting portions 40 and the first virtual line L1 is 60 degrees.

[0014] The pair of positioning protrusions 36 are provided at positions facing each other with the central hole 31 interposed therebetween, and as shown in FIG. 4, they are formed to protrude from the upper surface of the base portion 30. The fourth virtual line L4 connecting the pair of positioning protrusions 36 is in a direction different from the X-axis direction and the Y-axis direction. The intersection angle between the fourth virtual line L4 and the first virtual line L1 is 54 degrees. As shown in FIG. 5, the positioning protrusion 36 is provided to abut against the side surface of the rib 233 for positioning when the mounting bracket 3 is attached to the lower surface of the cover portion 23. The pair of connecting portions 40 are arranged along the inner peripheral surface of the outer peripheral wall 230, and screw holes 41 into which the bolts 25 are screwed are formed.

[0015] Next, the procedure for attaching the lighting device 1 to the pillar 6 and the beam 7 will be described with reference to FIG. 6. The pillar 6 and the beam 7 have thick portions 62 and 72 formed in the central portion in the width direction sandwiched by the dotted lines 61 and 71, and the mounting bracket 3 is screwed to these thick portions 62 and 72. When attaching the mounting bracket 3 to the pillar 6, first draw vertical ruled lines 65 and horizontal ruled lines 66 on the pillar 6. Then, position the mounting bracket 3 based on the extending direction of the wiring 24. That is, when the wiring 24 extends downward along the pillar 6, arrange the mounting bracket 3 so that the arrow of the wiring direction indicating portion 34 faces downward. Check the vertical ruled line 65 from the first hole 32, check the horizontal ruled line 66 from the second hole 33, and check the intersection of the vertical ruled line 65 and the horizontal ruled line 66 from the center hole 31. Thereby, the mounting bracket 3 can be positioned based on the vertical ruled line 65 and the horizontal ruled line 66. Then, screw a screw into the thick portion 62 through the first hole 32 overlapping the thick portion 62 to attach the mounting bracket 3 to the pillar 6.

[0016] To attach the mounting bracket 3 to the beam 7, draw vertical ruled lines 75 and horizontal ruled lines 76 on the beam 7, and position the mounting bracket 3 based on the extending direction of the wiring 24. For example, when the wiring 24 extends rightward along the beam 7, arrange the mounting bracket 3 so that the arrow of the wiring direction indicating portion 34 faces rightward. Check the horizontal ruled line 76 from the first hole 32, check the vertical ruled line 75 from the second hole 33, and check the intersection of the vertical ruled line 75 and the horizontal ruled line 76 from the center hole 31. Thereby, the mounting bracket 3 can be positioned based on the vertical ruled line 75 and the horizontal ruled line 76. Then, screw a screw into the thick portion 72 through the first hole 32 overlapping the thick portion 72 to attach the mounting bracket 3 to the beam 7. Also, when the wiring 24 extends downward from the beam 7 along the pillar 6, arrange the mounting bracket 3 so that the arrow of the wiring direction indicating portion 34 faces downward. Check the vertical ruled line 75 from the first hole 32, check the horizontal ruled line 76 from the second hole 33, and check the intersection of the vertical ruled line 75 and the horizontal ruled line 76 from the center hole 31. Thereby, the mounting bracket 3 can be positioned based on the vertical ruled line 75 and the horizontal ruled line 76. Then, screw a screw into the thick portion 72 through the second hole 33 overlapping the thick portion 72 to attach the mounting bracket 3 to the beam 7.

[0017] Next, the light fixture 2 is attached to the mounting bracket 3. That is, the wiring 24 pulled out from the opening groove 231 of the light fixture 2 is directed in the direction of the arrow on the wiring direction indicator part 34 of the mounting bracket 3, and the light fixture 2 is positioned in alignment with the mounting bracket 3. At this time, the connecting part 40 is positioned on the inside of the outer peripheral wall 230. Then, when the light fixture 2 is positioned by bringing the positioning projection 36 and the rib 233 into contact, the through hole 232 and the screw hole 41 are aligned coaxially, and the bolt 25 can be screwed from the through hole 232 into the screw hole 41 to attach the light fixture 2 to the mounting bracket 3. As a result, the lighting device 1 can be attached to the column 6 or beam 7.

[0018] Furthermore, if the column 6 or beam 7 to which the lighting device 1 is attached has an opening for inserting the wiring 24 into the interior, the wiring 24 may be passed through the central hole 31 and routed into the interior of the column 6 or beam through the opening formed in the column 6 or beam.

[0019] [Effects of the Embodiment] According to the lighting device 1, the mounting bracket 3 for attaching the light fixture 2 is provided with a pair of first holes 32 and a pair of second holes 33 formed perpendicular to each other. Therefore, the vertical lines 65, 75 and horizontal lines 66, 76 drawn on the object to be attached, such as the column 6 and beam 7, can be seen through these first holes 32 and second holes 33, and the mounting bracket 3 can be easily aligned with the vertical lines 65, 75 and horizontal lines 66, 76. Furthermore, the wiring direction indicator 34 allows the mounting bracket 3 to be installed in a orientation that allows the wiring 24 to extend in the correct direction, so when the light fixture 2 is attached to the mounting bracket 3, the wiring 24 from the light fixture 2 can be extended in the correct direction.

[0020] Since a central hole 31 is formed at the reference position of the base portion 30 of the mounting bracket 3, the intersections of the vertical lines 65, 75 and the horizontal lines 66, 76 can be seen from the central hole 31, making it easier to position the mounting bracket 3. The central hole 31 is sized to allow the connector 241 of the wiring 24 to pass through, so the wiring 24 extending from the light fixture 2 can be pulled out through the central hole 31. For this reason, a hole for inserting the wiring can be formed in the mounting part such as a pole 6, and by aligning the position of this hole with the central hole 31, the wiring 24 can also be positioned by passing it through the hole for inserting the wiring in the mounting part.

[0021] Since the central hole 31 and the second hole 33 are connected via the opening 35, the central hole 31, the second hole 33, and the opening 35 can be formed in a single press operation. This reduces the number of processing steps, allowing the mounting bracket 3 to be manufactured in a short time and at low cost.

[0022] [Differentiation] The mounting bracket is not limited to the above embodiment, and the mounting bracket 3B shown in Figure 7 may be used. Mounting bracket 3B differs from mounting bracket 3 in that the size of the central hole 31B formed in the base portion 30B is small and is provided only for the purpose of checking the marking lines, and that the pair of first holes 32B and the pair of second holes 33B are both independent through holes and do not communicate with the opening 35B formed for cutting and bending the connecting portion 40B. Mounting bracket 3B has a wiring direction indicator portion 34B formed thereon, which consists of an arrow engraved in the same way as the wiring direction indicator portion 34. This mounting bracket 3 also has a center hole 31B, a first hole 32B, and a second hole 33B that allow the marking lines to be seen, so the mounting bracket 3B can be easily aligned with the marking lines. In addition, the wiring direction indicator 34B allows the mounting bracket 3B to be installed in a direction in which the wiring 24 extends in the correct direction, so when the light fixture 2 is attached to the mounting bracket 3B, the wiring 24 from the light fixture 2 can be extended in the correct direction. Furthermore, although the size of the central hole 31B is small and it is not possible to insert the wiring 24 or connector 241 through the central hole 31B, the small opening area of ​​the base portion 30B improves the rigidity of the base portion 30B.

[0023] The mounting bracket only needs to have a pair of first holes 32 and a pair of second holes 33 that are arranged orthogonally to each other in order to position it relative to the marking line, and a center hole 31 is not necessarily required. The wiring direction indicator section 34 is not limited to an arrow marking; it may be a mark other than an arrow, or only the first hole 32 on the wiring direction side may be an elongated hole, as long as it can be recognized as the wiring direction by the worker. Furthermore, the wiring direction indicator section 34 is not limited to being formed between the central hole 31 and the first hole 32; it may also be formed between the central hole 31 and the second hole 33.

[0024] The planar shape of the light fixture 2 and mounting brackets 3 and 3B, as viewed from the Z-axis direction, is not limited to a circle; it may be a polygon with triangles or more sides, or an ellipse, heart shape, star shape, etc., and should be set appropriately with design considerations in mind. Furthermore, the mounting brackets 3 and 3B may have a different planar shape from the light fixture 2, and the reference position corresponding to the intersection of the ruled lines may be set at a position offset from the planar center of the mounting bracket, rather than at the planar center. The configuration of the light fixture 2 is not limited to the above embodiment, and any fixture that can be attached to the mounting brackets 3 and 3B is acceptable. For example, in the case of a lighting device 1 attached to a column 6 or beam 7, a light fixture 2 that can be set to direct the light downwards or in other directions may be used. The object to which the lighting device 1 is attached is not limited to columns 6 or beams 7, but may also be the exterior walls or fences of a building, or decking or flooring materials for balconies, etc.

[0025] [Summary of the invention] The present invention relates to a lighting device comprising a mounting bracket fixed to an object to be mounted, and a light fixture attached to the mounting bracket, wherein the mounting bracket is characterized by having a pair of first holes formed at positions opposite each other on a plane with respect to a reference position, a pair of second holes formed at positions opposite each other on a plane with respect to the reference position and on a second virtual line perpendicular to a first virtual line connecting the pair of first holes, and a wiring direction indicator portion indicating the wiring direction from which the wiring of the light fixture extends. According to the present invention, the mounting bracket for attaching the light fixture is provided with a pair of first holes and a pair of second holes formed perpendicular to each other. This allows the user to see the marking lines drawn on the object to be attached, such as a pole, through these holes, and to easily align the mounting bracket with the marking lines. Furthermore, the wiring direction indicator allows the mounting bracket to be installed in a orientation that allows the wiring to extend in the correct direction. Therefore, when the light fixture is attached to the mounting bracket, the wiring from the light fixture can be extended in the correct direction.

[0026] In the lighting device of the present invention, it is preferable that a central hole is formed at the reference position of the mounting bracket. According to the present invention, since a central hole is formed at the reference position of the mounting bracket, the intersection of the marking lines can be confirmed from the central hole, making it easier to position the mounting bracket.

[0027] In the lighting device of the present invention, it is preferable that a connector for connecting to other wiring is attached to the wiring, and that the central hole is formed to a size that allows the connector and the wiring to be inserted. According to the present invention, the central hole is formed to a size that allows wiring and connectors to be inserted, so that wiring extending from the light fixture can be pulled out through the central hole. For this reason, by forming a hole for inserting wiring in the mounting part, such as a column to which the lighting device is attached, and aligning the position of this hole with the central hole, the wiring can also be arranged by passing it through the hole for inserting wiring in the mounting part.

[0028] In the lighting device of the present invention, it is preferable that an opening is formed that connects the central hole with the first hole or the second hole. According to the present invention, since the central hole and the first or second hole are connected, the central hole and the first or second hole can be formed in a single press operation. Therefore, the number of processing steps can be reduced, and mounting brackets can be manufactured in a short time and at low cost. [Explanation of Symbols]
