  Hereinafter, an example of an embodiment of a lighting device according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view schematically illustrating a configuration of a lighting device according to a first embodiment of the present invention.
The illuminating device 10 has a plurality of casings 12-1, 12-2, and 12-3 that are formed in a substantially cubic shape as a whole and in which a light source is disposed in a hollow interior 12a.

  Note that the casing 12-1, the casing 12-2, and the casing 12-3 have the same configuration. Therefore, in the following description, the case 12-1 (see FIG. 2) will be described in detail, and the same or equivalent configuration as the case 12-1 will be referred to with reference to the case 12-1. The configurations of the casing 12-2 and the casing 12-3 to be used are indicated by the same reference numerals as those used in FIGS. 1 to 8, and the detailed configuration and description of the operation are omitted.

  The casing 12-1 constituting the lighting device 10 is formed in a substantially cubic shape as a whole, and all have six side surfaces having outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g having a substantially square shape. The interior 12a is a hollow interior space formed by the six side surfaces.

  The housing 12-1 can be formed of, for example, a translucent resin, and in this embodiment, the six side surfaces are each formed of a translucent acrylic plate having a milk color. By forming the casing 12-1 with such a translucent material, light projected from the light source disposed in the interior 12a can be effectively emitted to the outside, which is suitable as a lighting device. is there.

  Note that the overall dimensions of the housing 12-1 can be, for example, L1 = 150 mm, L2 = 150 mm, and L3 = 150 mm (see FIG. 2).

  Then, ring-shaped magnets 14N and 14S and magnets are arranged so as to be positioned at substantially central portions of the six substantially square outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g of the casing 12-1. Magnets 16N and 16S are arranged on the inner peripheral side of 14N and 14S, and magnets 16N and 16S are located with a predetermined distance.

  The magnets 14N and 14S (see FIG. 3A) and the magnets 16N and 16S (see FIG. 3B) are permanent magnets and have conductivity.

  Of the six outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g, the four outer peripheral surfaces 12b, 12c, 12d, and 12e each have a magnet 14N that forms an N pole and a magnet that forms an S pole. 16S (see FIG. 3C). On the other hand, the remaining two outer peripheral surfaces 12f and 12g are respectively provided with a magnet 14S forming an S pole and a magnet 16N forming an N pole (see FIG. 3D).

  The diameters of the magnets 16N and 16S are set to be smaller than the inner diameters of the magnets 14N and 14S, and the magnets 16N and 16S disposed on the inner peripheral side of the magnets 14N and 14S are magnetized to the magnets 14N and 14S. It is set so that it can be arranged in a state having a predetermined interval from 14S.

  For example, as the magnets 14N and 14S, ring-shaped permanent magnets having a thickness L4 = 1.9 mm, an outer diameter L5 = 12.2 mm, and an inner diameter L6 = 8.4 mm are used (see FIG. 3A), and the magnets 16N and 16S are used. When a cylindrical permanent magnet having a thickness L7 = 1.9 mm and a diameter L8 = 6.2 mm is used (see FIG. 3B), 1.1 mm between the magnets 14N and 14S and the magnets 16N and 16S. (See L9 shown in FIGS. 3C and 3D).

  A ring shape having a predetermined depth from the surface of the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g is formed at the substantially central portion of each of the six outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g. The groove portion 20 and the cylindrical groove portion 22 are formed (see FIG. 4A).

  Various dimensions such as the depth and diameter of the groove portions 20 and 22 are such that the magnets 14N, 14S, 16N, and 16S can be fitted into the groove portions 20 and 22, and the magnets 14N and 14N located in the groove portions 20 and 22 can be fitted. The dimensions of the surfaces 14a, 16N, and 16S are set so that the heights of the surfaces 14a and 16a substantially coincide with the heights of the surfaces of the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g. For example, when a permanent magnet having a thickness of 1.9 mm is used as the magnets 14N and 14S, the depth of the groove 20 is 1.9 mm, and when a permanent magnet having a thickness of 1.9 mm is used as the magnets 16N and 16S, The depth of the groove 22 is set to 1.9 mm.

  Therefore, the surfaces 14a and 16a of the magnets 14N and 14S and the magnets 16N and 16S located at substantially the central portion of the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g are the outer peripheral surfaces 12b, 12c, and 12d. , 12e, 12f, and 12g, and does not protrude from the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g (see the state shown in FIG. 4B).

  Furthermore, holes 20a and 22a are formed in the bottom surfaces of the grooves 20 and 22 so as to pass through the side surfaces and open on the back surfaces of the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g. . Each of the holes 20a and 22a is provided with a wiring of a light emitting diode 30 as a light source to be described later (see FIG. 4B).

  Thus, a light emitting diode (LED) 30 is disposed as a light source in the hollow interior 12a composed of the six side surfaces where the magnets 14N, 14S, 16N, and 16S are respectively disposed.

  As the light emitting diode 30, various light emitting diodes that emit a predetermined color can be used. For example, light emitting diodes that emit blue, red, green, orange, yellow, white, or the like are arbitrarily selected and arranged. be able to. Thus, by using the light emitting diode 30 as a light source, current consumption can be kept low, energy saving and practicality can be improved.

  The light emitting diode 30 is covered with a diffusion sheet 32 (see FIG. 4B). The diffusion sheet 32 diffuses the light projected from the light emitting diode 30 and makes the amount of light from the light source uniform, thereby producing a non-uniform state.

  Each of the six light emitting diodes 30 is fixedly disposed on the back surface of each of the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g of the six side surfaces so as to be positioned in the inner portion 12a. (See FIG. 5).

  The wiring of the light emitting diode 30 is soldered to the magnets 14N, 14S, 16N, and 16S disposed in the groove portions 20 and 22 through holes 20a and 22a formed in the side surfaces (FIG. 4 ( b)). Then, as shown in FIG. 6, the six light emitting diodes 30 are connected to each other with a current reducing resistor 34 provided in the middle of the wiring, and the light emitting diode 30 and the magnets 14N, 14S, 16N, and 16S are electrically connected. Thus, the magnets 14N and 14S are designed to be negative poles, and the magnets 16N and 16S are designed to be positive poles (see FIGS. 3C and 3D).

  In this embodiment, a current is supplied to the lighting device 10 from the outside of the lighting device 10 by a power supply unit 36 as shown in FIG. This power supply unit 36 has an AC adapter (not shown) having a plug inserted into an outlet, a power supply side magnet 37S having the same configuration as the magnet 14S and forming the S pole, and the same configuration as the magnet 16N. And a power supply side magnet 38N that forms an N pole. In the power supply unit 36, the wiring is designed so that the power supply side magnet 37S becomes a negative pole and the power supply side magnet 38N becomes a positive pole.

  In the above configuration, in order to turn on the lighting device 10 according to the present invention, first, the user connects the power-side magnet 37S of the power supply unit 36 in which the plug is inserted into the outlet to the housing 12-1 of the lighting device 10. The magnet 14N disposed on the outer peripheral surface 12c is coupled, and the power supply side magnet 38N of the power supply unit 36 is coupled to the magnet 16S disposed on the outer peripheral surface 12c of the casing 12-1 of the lighting device 10 ( FIG. 6 and FIG. 7 (a)).

  At this time, since the magnet 14N disposed on the outer peripheral surface 12c of the casing 12-1 of the lighting device 10 is an N pole and the power supply side magnet 37S is an S pole, both the ring-shaped magnet 14N and the power supply side magnet 37S are used. Are attracted to each other by magnetic force and easily connected. Similarly, since the magnet 16S disposed on the outer peripheral surface 12c of the casing 12-1 of the lighting device 10 is the S pole and the power supply side magnet 38N is the N pole, both the columnar magnet 16S and the power supply side magnet 38N are used. Are attracted to each other by magnetic force and easily connected.

  The magnet 14N and the power supply side magnet 37S thus connected are both negative poles, and the magnet 16S and the power supply side magnet 38N are both positive poles, and current (for example, via the connected N pole and S pole magnets) , 15V) is supplied from the power supply unit 36 to the housing 12-1.

  Then, the light emitting diode 30 in the housing 12-1 electrically connected to the magnet 14N and the magnet 16S on the outer peripheral surface 12c is energized, and the light emitting diode 30 emits light in a predetermined color and is diffused by the diffusion sheet 32. Light is emitted from the translucent outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g to the outside, and the casing 12-1 is lit with no unevenness (see the state shown in FIG. 7A).

  Further, the magnet 14N disposed on the outer peripheral surface 12f of the housing 12-2 is coupled to the magnet 14N disposed on the outer peripheral surface 12e of the lighted housing 12-1, and the lighted housing is also connected. The magnet 16S disposed on the outer peripheral surface 12e of the body 12-1 is connected to the magnet 16N disposed on the outer peripheral surface 12f of the housing 12-2 (the broken line arrows shown in FIGS. 6 and 7A) (Refer FIG.7 (b)).

  At this time, since the magnet 14S disposed on the outer peripheral surface 12f of the casing 12-2 of the lighting device 10 is the S pole and the magnet 14N of the lit casing 12-1 is the N pole, both are ring-shaped. The magnet 14S and the magnet 14N are attracted to each other by a magnetic force and easily connected. Similarly, since the magnet 16N disposed on the outer peripheral surface 12f of the casing 12-2 of the lighting device 10 has an N pole and the magnet 16S of the lit casing 12-1 has an S pole, both are cylindrical. The magnet 16N and the magnet 16S are attracted to each other by a magnetic force and easily connected.

  Thus, when the casings 12-1 and 12-2 are connected by the magnet 14S and the magnet 14N and the magnet 16N and the magnet 16S, the connected magnet 14S and the magnet 14N are both negative poles, and the magnet 16N and the magnet 16S Are positive poles, and the current supplied from the power supply unit 36 to the light emitting diode 30 of the casing 12-1 is supplied to the casing 12-2 via the N-pole and S-pole magnets to be connected.

  Then, the light emitting diode 30 in the casing 12-2 electrically connected to the magnet 14S and the magnet 16N on the outer peripheral surface 12f is energized, and the light emitting diode 30 emits light in a predetermined color and is diffused by the diffusion sheet 32. Light is emitted to the outside from the translucent outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g, and the casing 12-2 is turned on together with the casing 12-2 in a non-uniform state (FIG. 7B). Refer to the state shown in the following).

  Furthermore, the magnet 14N disposed on the outer peripheral surface 12g of the housing 12-3 is connected to the magnet 14N disposed on the outer peripheral surface 12b of the housing 12-2 that is lit, and the light is lit. The magnet 16S disposed on the outer peripheral surface 12b of the housing 12-2 is connected to the magnet 16N disposed on the outer peripheral surface 12g of the housing 12-3 (the broken line arrow shown in FIG. 7B and FIG. 7). (See (c)).

  At this time, since the magnet 14S disposed on the outer peripheral surface 12g of the casing 12-3 of the lighting device 10 is an S pole and the magnet 14N of the lit casing 12-2 is an N pole, both are ring-shaped. The magnet 14S and the magnet 14N are attracted to each other by a magnetic force and easily connected. Similarly, since the magnet 16N disposed on the outer peripheral surface 12g of the casing 12-3 of the lighting device 10 has an N pole and the lit magnet 12S of the casing 12-2 has an S pole, both are cylindrical. The magnet 16N and the magnet 16S are attracted to each other by a magnetic force and easily connected.

  Thus, when the casings 12-2 and 12-3 are coupled by the magnet 14S and the magnet 14N and the magnet 16N and the magnet 16S, the coupled magnet 14N and the magnet 14S are both negative poles, and the magnet 16S and the magnet 16N Are positive poles, and the current supplied from the casing 12-1 to the light emitting diode 30 of the casing 12-2 is supplied to the casing 12-3 via the N pole and S pole magnets to be connected. The

  Then, the light emitting diode 30 in the casing 12-3 electrically connected to the magnet 14S and the magnet 16N on the outer peripheral surface 12g is energized, and the light emitting diode 30 emits light in a predetermined color and is diffused by the diffusion sheet 32. Light is emitted from the translucent outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g to the outside, and the casing 12-3 is turned on together with the casing 12-1 and the casing 12-2 without any unevenness. (See the state shown in FIG. 7C).

  In this way, the magnets 14N, 14S, 16N, and 16S disposed on the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g of the casings 12-1, 12-2, and 12-3 are joined by magnetic force. By doing so, the casings 12-1, 12-2, and 12-3 are physically connected and integrated, and the electrical connection is established through the magnets 14N, 14S, 16N, and 16S to light up. .

  Therefore, if the power supply unit 36 attached to the outer peripheral surface 12c of the housing 12-1 is removed from the outer peripheral surface 12c and the bonding of the magnet 14N and the power supply side magnet 37S and the magnet 16S and the power supply side magnet 38N is released, The casing 12-1, the casing 12-2, and the casing 12-3 are all turned off.

  As described above, the lighting device 10 according to the present invention includes the three casings 12-1, 12-2, and 12-3 in which the light emitting diodes 30 are disposed in the interior 12a. Since magnets 14N, 14S, 16N, and 16S are arranged on outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g of 1, 12-2 and 12-3, respectively, magnets 14N, 14S, 16N, and 16S are used. Since the casings 12-1, 12-2, and 12-3 are separably connected to each other and the casings 12-1, 12-2, and 12-3 can be arbitrarily arranged, the degree of freedom is very high. It has a high appearance and a beautiful appearance with high design, and is practical and extremely valuable as an interior.

  That is, as described above, the casing 12-1 and the casing 12-2 are adjacent to each other in a state where the outer peripheral surface 12e and the outer peripheral surface 12f are in surface contact, and the outer peripheral surface 12b and the outer peripheral surface 12g are in surface contact. Arrange the three casings 12-1, 12-2, 12-3 so that the casing 12-3 is stacked above the casing 12-2 (see FIG. 1 and FIG. 7C). Of course, it is not limited to.

  For example, as shown in FIG. 8A, the casing 12-2 is stacked above the casing 12-1 with the outer peripheral surface 12f and the outer peripheral surface 12b being in surface contact, and the outer peripheral surface 12d and the outer peripheral surface The housing 12-3 may be stacked above the housing 12-2 with the surface 12g in surface contact. Alternatively, as shown in FIG. 8B, among the three stacked casings 12-1, 12-2, 12-3, a casing sandwiched between the upper and lower casings 12-1, 12-3. The body 12-2 can be rotated and disposed so that the outer peripheral surface 12f of the housing 12-1 and the outer peripheral surface 12b of the housing 12-2 do not come into surface contact with each other.

  That is, in the lighting device 10 according to the present invention, the magnets 14N, 14S, 16N, and 16S are abbreviated to the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g of the casings 12-1, 12-2, and 12-3. Since it is arranged in the central part, the connection with the other casings is ensured while maintaining the connection between the casings 12-1, 12-2, 12-3 by the magnets 14N, 14S, 16N, 16S. Casings 12-1, 12-2, 12-3 with the axes perpendicular to the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, 12g on which the magnets 14N, 14S, 16N, 16S are disposed as rotation axes The degree of freedom is further improved.

  Moreover, when using the illuminating device 10, as shown to Fig.7 (a) (b) (c) one by one, a user respectively connects three housing | casing 12-1, 12-2, 12-3. It is possible to check the overall arrangement shape and lighting state while sequentially lighting.

  In the lighting device 10 according to the present invention, the magnets 12-1, 12-2, 12-3 are connected to each other as described above to form an arbitrary shape and ensure electrical connection. Since the coupling and repulsion of 14N, 14S, 16N, and 16S are used, it is not necessary to use any tools, and parts such as screws are not used. Thus, since the illuminating device 10 by this invention is a very simple structure, it can reduce manufacturing cost and can be manufactured cheaply, and anyone can use it easily.

  Moreover, in the illuminating device 10 by this invention, the housing | casing 12-1, 12-2, 12-3 is provided with the same structure, Comprising: These housing | casing 12-1, 12-2, 12-3 If each of the six side portions is formed of a translucent acrylic plate having a milk color, it can be assembled by 18 acrylic plates having the same configuration, and manufacturing and assembly are very easy.

  In the illumination device 10 according to the present invention, the surfaces 14a and 16a of the magnets 14N and 14S and the magnets 16N and 16S do not protrude from the surfaces of the outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g. When the casings 12-1, 12-2, and 12-3 are connected to each other (see FIG. 4B), the casings 12-1, 12-2, and 12-3 to be connected are connected. The outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g are closely attached to each other so that no gap is left, and the plurality of housings 12-1, 12-2, and 12-3 are accurately arranged in an arbitrary shape. Can be prevented from being misaligned.

  In the illumination device 10 according to the present invention, the magnet 14N that forms the N pole is disposed on the outer peripheral side of the magnet 16S that forms the S pole, and the S pole is disposed on the outer peripheral side of the magnet 16N that forms the N pole. Since the magnet 14S to be formed is disposed, the N-pole magnets 14N and 16N and the S-pole magnets 14S and 16S are always within the single outer peripheral surfaces 12b, 12c, 12d, 12e, 12f, and 12g. Are arranged so that the magnets 14N and 14S located on the outer peripheral side are negative poles and the inner magnets 16N and 16S are positive poles. For this reason, it is possible to prevent the negative pole and the positive pole from being misplaced, and it is possible to eliminate inconveniences such as a short circuit of the power source and the non-lighting of the light emitting diode 30 due to the mistaking of the minus pole and the plus pole.

  Next, a second embodiment of the illumination device according to the present invention will be described with reference to FIGS. 9 to 10.

  9 to 10, the same or corresponding components as those shown in FIGS. 1 to 8 are described in detail by using the same reference numerals as those used in FIGS. 1 to 8. A description of the configuration and operation is omitted.

  That is, the illuminating device 40 includes four corner portions of each of the six substantially square outer peripheral surfaces 42b, 42c, 42d, 42e, 42f, and 42g in each of the housings 42-1, 42-2, and 42-3. Four cylindrical magnets 48N and 48S are arranged so as to be positioned in the vicinity. The magnets 48N and 48S are both permanent magnets and have conductivity.
