Problems to be Solved by the Invention

[0004] Power supply to such a flexible tube type light is performed, for example, directly via an electric wire from an external power source arranged on the back side of a wall surface. Therefore, it is necessary to drill a hole for drawing in the electric wire in the base plate using a dedicated tool such as a drill, or to let the electric wire crawl on the wall surface of the base plate. Not only is the assembly troublesome, but also the appearance is not good because the electric wire is exposed.

[0005] Furthermore, when attaching flexible tube-type lights to a base plate, for example, the non-emitting surface of the tube was clamped between U-shaped fixing clips made of metal or synthetic resin, and these fixing clips were screwed to the base plate. Alternatively, the fixing clips or the back surface of the tube were fixed to the base plate via double-sided tape. When using screws, changing the position or shape of the flexible tube-type light required removing the screws, which was time-consuming and left screw holes in the base plate. When using double-sided tape, it was less time-consuming than using screws, but there were problems such as a decrease in adhesive strength over time and the residue of adhesive material remaining on the wall when removed.

[0006] This invention was made in view of the above circumstances, and aims to provide a magnetically attached illuminated device that is easy to assemble and has a superior appearance. [Means for solving the problem]

[0007] The present invention takes the following measures to solve the above problems. The symbols in parentheses attached to each component in this section ("Means for Solving the Problems") are for reference purposes only to indicate the correspondence with the specific means described in the embodiments later, and the present invention is not limited to these.

[0008] One aspect of the present invention is a magnetically attached decorative lighting device (1) comprising a light-emitting item (4), a magnetic wall (2, 2A) having a ferromagnetic material as a component, a mounting part (6) for detachably fixing the light-emitting item (4) to the magnetic wall (2) by magnetic attraction force, a power supply (31) for supplying power to the light-emitting item (4), and an electric wire (52) for electrically connecting the power supply (31) and the light-emitting item (4), wherein the light-emitting item (4) is fixed to a desired position on the magnetic wall (2, 2A) by the mounting part (6), and through-holes (20K, 21K) are provided on the magnetic wall (2, 2A) at positions corresponding to the connection parts (471, 472) between the light-emitting item (4) and the electric wire (52) that penetrate the wall surface (2S) in the thickness direction, and power is supplied from the power supply (31) to the light-emitting item (4) with the electric wire (52) inserted through the through-holes (20K, 21K).

[0009] In another aspect of the present invention, the magnetic wall (2,2A) comprises a base plate (20) and a soft magnetic sheet (21) detachably laminated on the base plate (20), and the through portion (20K,21K) is composed of a through space (20K) formed in the base plate (20) and a cut (21K) formed in the soft magnetic sheet (21) that communicates with the through space (20K) of the base plate (20) when the soft magnetic sheet (21) is laminated on the base plate (20).

[0010] In another aspect of the present invention, the base plate (20) is made of a magnetic sheet (20A), and the mounting portion (6) has a magnetic sheet (60) with a different magnetization pitch than the magnetic sheet (20A) of the base plate (20) as a means for magnetic attraction to the magnetic wall (2A).

[Modes for carrying out the invention]

[0013] Embodiments of the present invention will be described below with reference to the attached drawings. Note that the scale and angles of the components shown in the attached drawings do not necessarily correspond to the actual objects, but have been adjusted to a size that is easy to illustrate. In this specification, "~" is used to include the values ​​before and after it as the lower and upper limits, respectively. Magnetic adsorption may also be simply referred to as magnetic attachment.

[0014] First, the configuration of the magnetic attachment type electric decoration device 1 will be described using FIGS. 1 to 6. FIG. 1 is an external perspective view of the magnetic attachment type electric decoration device 1. FIG. 2 is a configuration diagram of the magnetic wall 2, (a) shows a partial front cutaway view, and (b) shows a cross-sectional view taken along the A-A line in (a). FIG. 3 is a diagram of the power supply unit 3 of the magnetic attachment type electric decoration device 1, (a) is an external perspective view, and (b) is a circuit diagram. FIG. 4 is a configuration diagram of the flexible tube type light 4, (a) shows an external perspective view, (b) shows a partial side cross-sectional view of the main part, and (c) shows a front view of the main part. FIG. 5 is a circuit diagram of the tape LED 40, and FIG. 6 is an external perspective view of the fixing holder 6.

[0015] As shown in FIG. 1, the magnetic attachment type electric decoration device 1 includes a magnetic wall 2, a power supply unit 3, a flexible tube type light 4, and a fixing holder 6. In the magnetic attachment type electric decoration device 1, the flexible tube type light 4 modeled in a desired shape can be magnetically attached to the magnetic wall 2 via the fixing holder 6, and power can be supplied from the power supply unit 3 to the flexible tube type light 4 to enable light emission.

[0016] The magnetic wall 2 is flat over the entire surface and has a wall surface 2S that can adsorb magnets, and has a laminated structure of a pedestal plate 20 and a soft magnetic sheet 21 as shown in FIG. 2. The area of the magnetic wall 2 is about A4 size in this embodiment, but is not limited thereto.

[0017] The pedestal plate 20 is a member that serves as the base of the magnetic wall 2, and is made of, for example, styrofoam, synthetic resin, coated paper, or wood with a thickness of about 2 mm to 10 mm. The pedestal plate 20 includes a plurality of square holes 20K penetrating in the thickness direction. The square holes 20K are sized such that the electric wires 52 and the male terminals 52t1, 52t2 connected to the flexible tube type light 4 can be inserted with a margin and the pedestal plate 20 can ensure appropriate rigidity.

[0018] The soft magnetic sheet 21 does not have the properties of a permanent magnet itself, but is a flexible sheet to which a magnet can be adsorbed, and is a mixture of fine powder of a soft magnetic material and a small amount of organic polymer elastomer serving as a binder, formed into a sheet shape with a thickness of 0.4 mm to 2 mm by a molding method such as rolling or extrusion.

[0019] As the soft magnetic material powder, a ferromagnetic material with low coercivity and high permeability (hereinafter referred to as "ferromagnetic material powder"), a ferromagnetic material with low coercivity and high permeability (hereinafter referred to as "ferrimagnetic material powder"), or a mixture of ferromagnetic material powder and ferrimagnetic material powder can be used. As the ferromagnetic material powder, iron powder, magnetic stainless steel powder, Sendust powder, etc. can be used. As the ferrimagnetic material powder, soft ferrites such as manganese zinc ferrite powder, nickel zinc ferrite powder, magnetite powder (iron(II,III) oxide powder), etc. can be used.

[0020] As a small amount of organic polymer elastomer to act as a binder, for example, chlorinated polyethylene, chlorosulfonated polyethylene, ethylene-vinyl acetate copolymer, ethylene-propylene rubber, nitrile rubber, acrylic rubber, chloroprene rubber, etc., can be used. In this embodiment, Iron Sheet (registered trademark) manufactured by the applicant company is used as such a soft magnetic sheet 21. Alternatively, instead of the soft magnetic sheet 21, a magnet sheet can be used, which is made by forming a mixture of fine powder of a hard magnetic material and an organic polymer elastomer to act as a binder into a sheet and magnetizing at least one side thereof.

[0021] The soft magnetic sheet 21 has two slit-shaped cuts 21K that penetrate from the front surface to the back surface. The cuts 21K are sized so that the electric wires 52 and male terminals 52t1 and 52t2 connected to the flexible tube-type light 4 can be inserted when the sheet is spread out laterally, and are preferably 2 cm to 5 cm in length. The soft magnetic sheet 21 is attached to the base plate 20 in a detachable manner by being positioned opposite the base plate 20 with a magnet sheet 23 in between. The back surface of the magnet sheet 23 is bonded to the base plate 20 via adhesive. A space S1 is formed between the soft magnetic sheet 21 and the base plate 20. The cutout 21K described above is in communication with the rectangular hole 20K of the base plate 20 when the soft magnetic sheet 21 is laminated and fixed to the base plate 20. These cuts in 21K are formed during assembly, as will be described later.

[0022] The power supply unit 3 has the function of supplying DC power to the flexible tube-type light 4, and as shown in Figure 3, it comprises a power supply 31, a wire 32, and a power distribution unit 33.

[0023] The power supply 31 consists of a battery with sufficient voltage and current to light the flexible tube-type light 4, or an adapter that converts commercial AC power to DC output.

[0024] The electric wire 32 consists of a two-wire cable with two lead wires connected in parallel to each other. In each diagram, to make the connection of the lead wires easier to understand, each lead wire of the two-wire cable is depicted as an independent wire. Two wires at one end of the electric wire 32 are electrically connected to the positive and negative terminals of the power supply 31, while the other two wires are connected to male terminals 32t1 and 32t2. The male terminals 32t1 and 32t2 have pins that can be detachably inserted into the female terminals 33t1 and 33t2 of the power distribution unit 33 described below, and the overall maximum width is about 3 mm.

[0025] The power distribution unit 33 consists of a breadboard in which a row of female terminals 33t1 arranged in a straight line and a row of female terminals 33t2 arranged in a straight line are arranged parallel to each other. In one female terminal row, the female terminals 33t1 are electrically conductive to each other, and in the other female terminal row, the female terminals 33t2 are electrically conductive to each other. Furthermore, the female terminals 33t1 in one female terminal row and the female terminals 33t2 in the other female terminal row are insulated from each other.

[0026] The flexible tube-type light 4 is configured as shown in Figure 4(a), with a tape LED 40 covered by an outer tube GT. As shown in Figure 4(b), the LED strip 40 has a configuration in which multiple unit LED strips 41 are continuously connected in the longitudinal direction. Each unit LED strip 41 is provided with a horizontally elongated, sheet-like substrate 42. The substrate 42 is made of a flexible synthetic resin sheet and is continuously connected in a tape-like manner in the longitudinal direction. This flexibility is in the direction normal to the substrate surface.

[0027] LED chips 43 and resistors 44 are mounted on the front surface of the substrate 42, and printed wiring 46 (see Figure 5) is laminated on the back surface of the substrate 42. A pair of bypass wires 451 and 452 are provided on the back side of the circuit board 42, extending along the entire length of the LED strip 40. The bypass wires 451 and 452 also serve to compensate for the increased electrical resistance of the positive and negative terminal wiring 461 and 462 in the printed circuit board 46. They also ensure that power is supplied to the unit LED strip 41 even when it is cut at the cut line CL. The pair of bypass wires 451 and 452 are insulated from each other by an insulating material.

[0028] The printed circuit board 46 consists of a positive electrode wire 461, a negative electrode wire 462, and a connecting wire 463, as shown in Figure 5. The negative electrode wire 462 is provided at a distance from the positive electrode wire 461, and the connecting wire 463 is provided between the positive electrode wire 461 and the negative electrode wire 462. The positive electrode wires 461 of adjacent unit tape lights 41, 41 are continuously connected to each other, and the negative electrode wires 462 of adjacent unit tape lights 41, 41 are continuously connected to each other.

[0029] The LED chip 43 and the resistor 44 are connected in series by a connecting wire 463. The positive terminal of the LED chip 43 is connected to the positive wire 461 or the resistor 44, and the negative terminal of the LED chip 43 is connected to the negative wire 462 or the resistor 44. The LED chips 43 can emit light in various colors such as blue, red, green, white, orange, and pink. However, for a single flexible tube-type light 4, all LEDs may be the same color, or a mixture of different colors may be used.

[0030] The outer tube GT is a long, hollow body made of silicone resin and is flexible. The upper surface G1 of the outer tube GT is made of a translucent material that allows light to pass through, while the other surfaces are opaque (for example, opaque white). Furthermore, by embedding a metal wire 48 with a diameter of approximately 0.5 mm to 2 mm, such as an aluminum wire, in the outer tube GT, which extends continuously along its longitudinal direction, the tube is able to resist the force that would cause it to return to its original shape and maintain its bent state, thereby providing excellent shape-following capabilities.

[0031] The flexible tube-type light 4 can be cut (divided) along the cut line CL for each unit tape light 41, and each cut element is flexible, retains its shape, and can emit light. Therefore, it can be used individually or combined with cut pieces or pieces of different colors to create various letters, shapes, and symbols, and by attaching it to a magnetic wall 2 which serves as a base plate, colorful illuminated signs and illuminated walls can be realized.

[0032] The flexible tube-type light 4 is connected to a wire 52 that receives power from a power source 31. The electric wire 52 consists of a two-wire cable with two lead wires arranged parallel to each other. Similar to the electric wire 32, in each figure, the lead wires of the two-wire cable 52 are depicted as independent wires. Two wires at one end of the electric wire 52 are electrically connected to the input terminals 471 and 472 of the flexible tube-type light 4, while the two wires at the other end are connected to two detachable male terminals 52t1 and 52t2 of the female terminals 33t1 and 33t2 of the power distribution unit 33, similar to the electric wire 32.

[0033] The connection between the electric wire 32 and the flexible tube-type light 4 may be made at the input terminals 471 and 472 at the longitudinal ends of the flexible tube-type light 4, but it is more preferable to use the inner input terminals 471 and 472. This is because connecting to the ends would make the lead wires more noticeable.

[0034] The fixing holder 6 consists of a clip CP and a magnet piece 60, as shown in Figure 6. The clip CP and the magnet piece 60 are fixed together with adhesive. The clip CP is a clamping body made of metal or synthetic resin, with a roughly U-shape when viewed from the front, and consists of a rectangular base plate CP1 and two side plates CP2. The side plates CP2 extend from both ends of the base plate CP1 in the same direction perpendicular to the base plate surface and are positioned opposite each other, forming a roughly U-shaped space S2 inside. The flexible tube-type light 4 housed in this space S2 is fixedly held in place by being clamped by both side plates CP2. The flexible tube-type light 4 housed in space S2 can slide longitudinally within the clip CP. This allows for fine adjustment of the mounting position of the flexible tube-type light 4 on the magnetic wall 2. The magnet piece 60 is said to be a magnet sheet cut to an appropriate size, but a sintered magnet may also be used.

[0035] Next, the assembly method of the magnetically attached lighting device 1 will be explained using Figures 7, 8, 9, and 10. Figure 7 is a flowchart showing the assembly procedure for the magnetic lighting device 1, Figure 8 is an external perspective view showing the wiring connection state of the magnetic lighting device 1, and Figure 9 is a circuit diagram showing the wiring connection state of the magnetic lighting device 1. Figure 10 shows the state of mounting the flexible tube-type light 4 to the magnetic wall 2, where (a) is a front view and (b) is a view of (a) along the BB line. Figure 11 is an enlarged view of the area enclosed by the dashed line in Figure 10(b). In the following description, the magnetic wall 2 is assumed to be placed horizontally on a workbench or the like, the male terminal 32t1 of the electric wire 32 is assumed to be pre-inserted into the female terminal 33t1 of the power distribution unit 33, and the male terminal 32t2 of the electric wire 32 is assumed to be inserted into the female terminal 33t2 of the power distribution unit 33.

[0036] As shown in Figure 7, the assembly of the magnetically attached lighting device 1 is carried out in the following order: step S11 of molding the flexible tube-type light, step S12 of temporarily placing the flexible tube-type light, step S13 of forming the cuts, step S14 of inserting the electric wires, step S15 of magnetically attaching the flexible tube-type light, and step S17 of connecting the power line. The contents of each step are described below.

[0037] [Step S11] First, the flexible tube-shaped light 4 is molded into the desired shape. In this example, it is the letter "U". [Step S12] Next, the flexible tube-shaped light 4, molded into the desired shape, is temporarily placed at the desired position on the magnetic wall 2, that is, at the target position on the wall surface 2S of the magnetic wall 2. Before temporarily placing it, as described in step S15 below, attaching the fixing holder 6 to an appropriate position on the molded flexible tube-shaped light 4 and then temporarily placing it by magnetic attachment makes the work easier as the flexible tube-shaped light 4 can be fixed in place.

[0038] [Step S13] Next, cuts 21K are formed in the magnetic wall 2 at the positions corresponding to the input terminals 471 and 472, which will be the connection points with the electric wire 52 in the temporarily placed flexible tube-type light 4. Here, since the soft magnetic sheet 21 is an iron sheet, the cuts 21K can be easily formed with, for example, a cutter blade. The cuts 21K are formed at the locations corresponding to the rectangular holes 20K in the base plate 20. When forming the cuts 21K, it is easier to work if the temporarily placed flexible tube-type light 4 is moved to a different location a short distance away.

[0039] [Step S14] Next, the cut 21K in the magnetic wall 2 is slightly widened, the male terminals 52t1 and 52t2 of the electric wire 52 connected to the flexible tube-type light 4 are passed through, and after passing through the space S1 between the soft magnetic sheet 21 and the base plate 20, the electric wire 52 is inserted through the rectangular hole 20K in the base plate 20 and pulled out from the back side.

[0040] [Step S15] Next, a fixing holder 6 is attached to a suitable position on the flexible tube-type light 4, and the flexible tube-type light 4 with the fixing holder 6 attached is brought to a position near the target location on the wall surface 2S of the magnetic wall 2. At this position, the back side (magnetic attachment surface) of the magnet piece 60 of the fixing holder 6 is brought close to the wall surface 2S. As a result, the magnetic attachment surface of the magnet piece 60 is attracted to and magnetically attached to the magnetic wall 2, fixing it in place. At this time, the input terminals 471 and 472 to which the electric wire 52 is connected are located almost directly above the cut 21K, so by further pulling the electric wire 52 through the cut 21K from the back side, the electric wire 52 can be prevented from appearing on the wall surface 2S. Perform the above steps for all the flexible tube-type lights 4 to be installed. In this example, the flexible tube-type light 4 designated as "1" will be magnetically attached using the same process.

[0041] [Step S17] Once the above procedure is completed for all flexible tube-type lights 4 (yes in step S16), insert the male terminals 52t1 and 52t2 of the wire 52 in each flexible tube-type light 4 into the female terminals 33t1 and 33t2 of the power distribution unit 33. This allows the DC power from the power supply 31 to be supplied to the flexible tube-type lights 4 via the wire 52, causing the flexible tube-type lights 4 to emit light.

[0042] As described above, with the magnetically attached lighting device 1, the flexible tube-shaped light 4, molded to the desired shape, is fixed to the desired position on the magnetic wall 2 by a fixing holder 6. In this case, the input terminals 471 and 472 to which the electric wires 52 are connected are located almost directly above the cut 21K of the flexible tube-shaped light 4, so that the electric wires 52 do not appear on the wall surface 2S. Therefore, the work of running the electric wires 52 along the wall surface 2S is unnecessary, making assembly easy and resulting in a superior appearance. Furthermore, since the soft magnetic sheet 21 is an iron sheet, the cut 21K can be easily formed with a cutter blade. After the cut 21K is opened on both sides and the electric wires 52 are inserted, the flexibility of the soft magnetic sheet 21 causes it to close back to its original shape, resulting in very little gap. From this point of view as well, the aesthetic appearance of the wall surface 2S can be ensured.

[0043] Furthermore, the flexible tube-type light 4 is fixed to the wall surface 2S of the magnetic wall 2 by magnetic attachment while the fixing holder 6 is attached, and since screws or adhesive tape are not required, it is easy to change the position or shape of the flexible tube-type light 4.

[0044] [Magnetic wall in a modified form] Next, we will describe the modified example of magnetic wall 2A. Figure 12 shows a modified configuration of magnetic wall 2A, where (a) is a partial front section view and (b) is a cross-sectional view of (a) taken along the CC line. In magnetic wall 2A, the base plate 20 of magnetic wall 2 itself is made of a magnetic sheet 20A. Its thickness is preferably about 2mm to 5mm. This is to reduce weight and ensure appropriate rigidity. As a result, the upper soft magnetic sheet 21 can be detachably fixed to the magnetic sheet 20A, which is the base plate, without the need to provide a separate magnetic sheet 23 as used in magnetic wall 2.

[0045] In this case, it is preferable to use a magnetization pitch for the magnet sheet 20A that is different from the magnetization pitch of the magnet piece 60 (magnet sheet) of the fixing holder 6. If the magnetization pitches were the same, the magnetization of the fixing holder 6 would be caused by the magnetic attraction of different magnetic poles on each magnet sheet, resulting in the magnet sheet of the fixing holder 6 being magnetized along the magnetization lines of the magnet sheet 20A on the magnetic wall side, thus limiting the degree of freedom in the orientation of the fixing holder 6.

[0046] Here, a magnetization line is a virtual boundary line between any one magnetic pole (e.g., the north pole) and an adjacent magnetic pole of the opposite polarity (e.g., the south pole) on the surface of a multi-pole magnetized magnet sheet. In reality, it is the white area that appears when a magnetic viewer sheet (a film in which microcapsules of magnetic fluid are uniformly dispersed) is placed in close contact with the magnet sheet, and it is a region where the magnetic field in the direction normal to the surface of the magnet sheet, i.e., perpendicular to the surface, is extremely weak or zero. In this modified example, a soft magnetic sheet 21 is laminated on top of the magnet sheet 20A, but because the soft magnetic sheet 21 is thin, the magnetic flux of the magnet sheet 20A passes through the soft magnetic sheet 21, and the magnetization line of the magnet sheet 20A appears on the wall surface 2S.

[0047] While embodiments of the present invention have been described above, the embodiments disclosed above are merely illustrative, and the scope of the present invention is not limited to these embodiments. The scope of the present invention is indicated by the claims and is intended to include all modifications within the meaning and scope equivalent to the claims. In other words, the overall or partial structure, shape, materials, number, circuit configuration, mounting position, and application of the magnetically attached lighting device 1 can be appropriately modified in accordance with the spirit of the present invention. [Industrial applicability]

[0048] It can be widely used as an advertising device installed in shop windows, storefronts, and exhibition booths, as well as a magnetically attached illuminated device suitable for decorating interior walls. [Explanation of Symbols]
