2. Description of the Related Art Conventionally, there has been known an illuminator configured such that a large number of illuminator bodies having connection members for mutual coupling and light conduction are provided at the apex portion of a regular polyhedron, and the illuminator bodies can be connected like a wall. (Patent Document 1). The illuminator body used in this example has one male plug and three female plugs, and each illuminator can be connected by detachably connecting these plugs. It is comprised as follows. The illuminator main body, which is a module for configuring each illuminator, is configured so that one incandescent bulb is arranged in the center of the interior and emits light through a hole formed in the side surface. . In addition, the plug for connection is configured by two poles (two connecting portions) as a pair.
There is also known an illuminating device including a light emitting diode having a cubic housing configured to be connected to each other (Patent Document 2).

Japanese Utility Model Publication No. 49-35993 Japanese Patent No. 4234094

Since the illuminator described in Patent Document 1 has an incandescent bulb as a light source, it consumes a large amount of power. When a large number of illuminators are connected, the power consumption increases and the amount of heat generated also increases. And even if a light source with low power consumption such as a light emitting diode is mounted on the illuminator, the electrical polarity (positive / negative) is reversed unless the direction of coupling is taken care of. It will not light up.
In addition, since the power supply terminals (plugs) are connected by simple insertion / extraction, they can be easily removed when a force is applied in the direction of separating them from each other. In such a case, the weight of the upper illuminator main body acts cumulatively on the connection portion between the lower illuminators, and there is a high possibility that the connection becomes unstable. Furthermore, since the plug is a portion that is heated by energization and the structural coupling is unstable as described above, it is also unstable in terms of electrical coupling.
Moreover, since the illuminator described in Patent Document 1 emits light from a single incandescent bulb, which is a point light source arranged in the center of the inside, through a hole formed in the side surface, the entire side surface has uniform illuminance. It cannot be made to emit light.

  Moreover, although the illuminating device of patent document 2 is a mutually connectable illuminating device which comprised the light emitting diode with little power consumption and calorific value, and comprised it so that a side surface might shine, it couple | bonds surfaces. As a result, the side surface serving as the coupling surface is a light emitting surface and is not exposed, and the light emitting surface cannot be used effectively.

The present invention has been invented in view of the above problems, and is a linking type lighting device having strength that can withstand the connection of a large number of modules and electrical connection stability, wherein a large number of modules are connected. Even if it is a case, it aims at providing the connection type illuminating device with less power consumption and the emitted-heat amount than before.
Further, even if the light emitting modules are connected without considering the direction of the light emitting modules, they can be coupled without reversing the electric polarity, and even a light source having a polarity such as a light emitting diode can be used. An object of the present invention is to provide a structure of a lighting device.
It is another object of the present invention to provide a structure of a linking type lighting device that is configured so that the entire side surface of the light emitting module emits light with substantially uniform illuminance and has no side surface that is blocked by connection with another light emitting module. Is.

  In order to solve the above problems, the present invention has the following means. That is, it is an illumination device in which a plurality of prismatic light emitting modules having a top surface formed in a regular polygonal shape such as a regular triangle, a regular square, a regular hexagon, and a bottom surface having the same shape as the top surface are connected. The light emitting module serving as a connecting unit has a panel formed of a transparent material forming each side surface, and thereby radiates internal light toward the outside. The panel is attached to a lattice-like frame having structural strength, and a light-emitting body with low power consumption such as a plurality of light-emitting diodes is provided on the inner surface side of each frame element constituting the frame. Further, in order to disperse the position of the light source, a light source is attached to the inner surface side of each frame element so that the panels on each side surface emit light with a uniform light amount. The light emitting modules serving as a connection unit have connecting portions on the outer peripheral edge of the upper surface and the outer periphery of the lower surface, respectively, and are connected to other light emitting modules arranged obliquely above or obliquely below. And each continuous connection part is formed in the structure which accept | permits such an oblique connection. In addition, each connecting part is provided with a power feeding part composed of contacts arranged at equal intervals in the order of positive and negative or negative positive and negative, and the power feeding parts provided in the connected modules are in a positional relationship facing each other. Are arranged at equal intervals in the center of the side portion. And it is comprised so that it may couple | bond with another light emitting module in the said connection part so that attachment or detachment is possible, and it couple | bonds electrically via the said electric power feeding part.

  Moreover, this invention has the following means. That is, the light emitting modules in the connecting portion are connected to each other through connecting means attached to the connecting portion, and the power feeding portions are connected to each other by a conductor built in the connecting means. Although this conductor is incorporated in the connection means, it is not involved in the structural coupling between the light emitting modules, and has a normal energizing action as long as it is normally connected by the connection means. . The light emitting modules to be connected are also connected by holding means prepared as separate means. The holding means connects the outer peripheral edge of the upper surface of the light emitting module located on the side where the connecting means is provided and the portion farthest from the connecting means on the upper surface of the light emitting module located below. This is a means for holding the posture of the light emitting module jumping out so as not to fall down.

  Moreover, this invention has the following means. That is, the light emitting module has a regular cubic shape.

  Moreover, this invention has the following means. That is, the conductor built in the connecting means protrudes from the surface of the connecting means with elasticity. There is a slight gap (so-called play) between the light emitting module and the connecting means to enable detachment, and the light emitting module and the connecting means have rigidity, but some bending occurs. For this reason, even if it is a case where the relationship between light emitting modules changes a little, a conductor protrudes with elasticity so that electrical conduction may be maintained.

Moreover, the light emitting module used for this invention has the following structures. That is, a prismatic light emitting module having a top surface formed in a regular polygon shape and a bottom surface having the same shape as the top surface, a panel formed of a transparent material forming each side surface, and a grid-like shape to which the panel is attached A connecting portion provided on the outer peripheral edge of the upper surface for connecting the frame, a plurality of light emitters provided on the inner surface side of each frame element constituting the frame, and other light emitting modules arranged obliquely above, and obliquely below There is a power supply unit composed of a connecting part provided on the outer peripheral edge of the lower surface for connecting to another light emitting module arranged, and contacts arranged at equal intervals in the order of positive / negative / positive / negative / positive provided in the connecting part. The connecting portion is detachably connected to another light emitting module, and is electrically connected to the power supply portion. The characteristics of the module are as described in the description of the lighting device.

The illuminating device according to the present invention connects a plurality of light emitting modules formed in the same shape, but can be connected obliquely upward rather than being stacked immediately above. Thereby, since it can connect, without blocking the upper surface or bottom face of each module, the illuminating device which exposed all the surfaces with a high illumination effect and a decoration effect can be provided. In addition, each light emitting module has a power feeding portion that does not change the electrical polarity even if the directions of the light emitting modules to be connected are different, so a module using a light source having a polarity like a light emitting diode. Even so, there is an effect that the connection can be performed without considering the direction of the connection.
In addition, while keeping the inside of the module hollow so that the light emitting surface is not shaded, a single light source is not provided in the center, but a light source is provided on each support in the module, so that each surface of the module can be irradiated uniformly. it can. As a result, all the surfaces appear to emit light uniformly, and the shadow of the column is less noticeable.
Further, the structural connection between the modules is performed by a connecting means having strength, and the electrical coupling is performed by a member built in the connecting means. As a result, it is possible to provide a lighting device that can stabilize the structural coupling and can perform an electrically stable connection.
In addition, since the power supply means for supplying power can be attached at an arbitrary position, there is an effect that power can be supplied to the lighting device without impairing the beauty.

The module 1 formed in a cubic shape has six square side panels 2 (2a, 2b, 2c, 2d, 2e, 2f) each having four corners chamfered in an arc shape with a predetermined radius on each side surface. Have.
The external shapes of the side panels 2 formed in a square shape are all the same, and the external shape is slightly smaller than the size of the original side surface forming a cube. As a result of forming the outer shape slightly smaller, a gap 3 having a predetermined width is formed at the boundary between other side panels adjacent to each other and orthogonal to each other. And the connection means etc. which are mentioned in detail are mounted | worn using the edge formed in the clearance gap 3 and the edge of each side panel 2 which forms the said clearance gap 3 in detail. That is, the gap 3 provided on each side of the module 1 constitutes a connecting portion with another module.

  FIG. 2 is an explanatory view showing the frame 4 for mounting the side panel 2 and the side panel 2 mounted on the frame 4. 2 shows only the four side panels 2c, 2d, 2e, and 2f, the side panels 2a and 2b shown in FIG. In this way, the six side panels 2 attached to the frame 4 form the side surfaces of the module 1 formed as a cube while providing the gaps 3 at the respective side portions. Further, as described above, since the corners of the side panel 2 are all rounded, a slightly large opening communicating with the space in the gap 3 is formed at the apex portion of the cube where the corners of each panel gather. The opening is used as an insertion port for the connecting means.

As an example, the side panel 2 is formed as a member integrally formed of a light-transmitting milky white plastic material. The side panel 2 has a rectangular plate-like portion 5 and is provided with a rectangular ridge 6 like a frame on the inner surface side of the plate-like portion 5 and slightly inside from the outer peripheral edge. . A plurality of (eight) convex pieces 7 are provided so as to protrude from the end face of the convex strip 6.
The ridges 6 are engaging means formed so as to be fitted with frame-shaped convex edges 8 provided on the respective side surfaces of the frame 4, and accurately determine the fixing position of the panel 2 with respect to the respective side surfaces of the frame 4. It has become a means of.

The convex piece 7 and the coupling portion 9 are coupled simultaneously with the engagement of the convex strip 6 and the convex edge 8 to fix the side panel 2 to the frame 4.

When the convex piece 7 of the side panel 2 is inserted into the coupling portion 9 of the frame 4, a projection (not shown) provided in the coupling portion 9 is engaged with a hole provided in the convex piece 7. The convex pieces 7 are held so as not to come off. The side panel 2 is fixed to the frame 4 by this engagement.
The frame 4 is formed as a lattice-shaped hollow member by twelve struts (frame elements) 10 constituting each side. An opening is formed on each side surface formed by the four support columns 10. The opening is formed so that the area is as wide as possible within a range in which the pillar, which is a frame element, can exhibit the mechanical strength necessary for coupling the modules. In other words, the support column 10 is formed in a shape and size that do not shrink the opening on the side surface as much as possible. The frame 4 is made of an electrically insulating resin material.

A part of the convex edge 8 and the two coupling portions 9 that form the above-described rectangle are provided on the surface portion of each column 10. In addition, a narrow circuit board (hereinafter referred to as “substrate”) 12 on which three light emitters (light sources) 11 each composed of a light emitting diode are mounted is fixed to the inner surface of each support column 10 as an example. Has been. The substrate 12 is formed to be thinner than each support column 10 and is electrically coupled to another substrate 12 adjacent at both ends in the longitudinal direction.
Further, three openings 13, 14, 15 communicating with the inside and the outside are provided in the central part of each column 10, and power supply terminals (power supply parts) 16, 17, 18 connected to the substrate 12 through the openings. Is to appear.

FIG. 3 is an explanatory diagram of the substrate 12.
3A is a plan view of the substrate 12, FIG. 3B is a front view of the substrate 12, and FIG. 3C is a side view of the substrate 12.
Three light emitting diodes are provided as the light emitter 11 on the surface of the substrate 12. The power supply terminals 16, 17, and 18 are provided on the back surface of the substrate 12. The power supply terminal has a central power supply terminal 17 as a positive electrode and power supply terminals 16 and 18 at both ends as negative electrodes, and is provided for power supply to the light emitter 11 and power supply to other modules. When the substrate 12 is mounted on the inner surface of each column 10, the power supply terminals 16, 17, and 18 are fitted into the openings 13, 14, and 15 from the inside of each column 10 to be exposed.
In addition, although it has described so that a flat electrode surface may be comprised in the figure, the surface of the support | pillar 10 or surface is actually used so that an electrode surface may not touch a person at the time of normal handling, or an accidental short circuit may occur. A metal terminal having a spring property is used as a contact point (a terminal of a connecting means to be described later) in contact with the power supply terminals 16, 17, and 18.

FIG. 3D is an explanatory diagram showing the arrangement of the twelve substrates 12 mounted in the frame 4. Since the board | substrate 12 is arrange | positioned in all the insides of the 12 support | pillar 10 combined in the grid | lattice form, as shown in FIG.3 (d), it arrange | positions so that a grid | lattice form may be comprised. All the substrates 12 are arranged such that the light emitting surface provided with the light emitter 11 faces the central portion inside the frame 4.
Further, both ends in the longitudinal direction of all the substrates 12 are electrically coupled to the other two adjacent substrates at the corners inside the frame 4. That is, on the inner side of the corner of the frame 4, the three substrates 12 are coupled to each other via soldering or electrical connector means.

  FIG. 4 is a circuit block diagram showing the connection state of the twelve substrates 12. Each substrate 12 has three-pole connecting portions arranged in the order of (−) (+) (−) at both ends in the longitudinal direction, and the three-pole connecting portions are connected to each other. Yes. The connection is made by soldering or connector means as described above. Each circuit connected to the connection portion of (−) (+) (−) is coupled to the power supply terminals 16, 17, and 18. That is, the power supply terminals 16 and 18 at both ends are connected to the (−) pole circuit, and the center power supply terminal 17 is connected to the (+) pole circuit.

With the above connection, when a predetermined power is supplied to any one of the substrates 12 via the power supply terminals 16, 17, 18, the power is also supplied to all the other substrates 12. On the substrate 12 to which power is supplied, the light emitter 11 mounted so as to face the inside of the frame 4 emits light.
The light radiated inward from the light emitters of the substrate 12 arranged in a grid pattern illuminates the entire inner surface of the hexahedron with a substantially equal amount of light, and thereby uniform from the surface of the milky white side panel 2 to the outside. It emits light.

The cube-shaped module 1 described as an example above can be connected to other modules having the same shape by using connection means.
5A shows the appearance of the connecting means 20 used for the connection, and FIG. 5B shows the appearance of the holding means 21. The connecting means 20 is formed as a strong plate-like member made of synthetic resin, and is attached to a connecting portion formed by the gap 3 of the module 1 at both side edges along the longitudinal direction. A mounting part is provided. As an example, the mounting portion is formed by a bulging portion 22 formed in a cross-sectional shape approximate to the internal shape of the gap 3. The said bulging part 22 is formed by forming a groove | channel along the longitudinal direction in the edge part of front and back. The edge of the side panel that forms the gap 3 comes into contact with the groove, and the connection means 20 can be fixed by preventing the bulging portion 22 from being detached by the groove. .
Further, since the shape of the gap 3 and the groove and the shape of the space formed between the gap 3 and the column 10 are formed to be substantially the same as the shape of the bulging portion 22, the attached connecting means 20 is a module. It is fixed while maintaining a constant posture without wobbling with respect to 1.

Since the corner portion of the module 1 is a portion where the corner portions of the three panels chamfered in an arc shape are gathered, an opening to the extent that the bulging portion 22 can be inserted inside the gap 3 in the corner portion. Is to be formed. In other words, the radius of the arc of the panel corner is determined in order to form the opening at the corner so as to allow the bulging portion 22 to be inserted.
The reason why the arc is chamfered is that the panel looks square when viewed from a distance. In other words, when the corner is formed by the straight C chamfering instead of the arcuate R chamfering, the appearance of the apparent panel appears as an octagon instead of a quadrangle. Therefore, in the present invention, the corners of the panel are formed in an arc shape.

  The connecting means 20 has three conductive terminals on both end faces in the lateral width direction. That is, as shown in FIG. 5 (a), three terminals 23a, 24a, 25a are provided on one side of the connecting means 20, and three terminals 23b, 24b, 25b are provided on the opposite side. . The terminals 23 a and 23 b, the terminals 24 a and 24 b, and the terminals 25 a and 25 b that are opposed to each other on the front and back sides are electrically connected inside the connection means 20. Further, these terminals 23, 24 and 25 are provided so as to protrude by a metal material having elasticity, and the connection stability is ensured by pressing with elasticity against the contacted portion. ing.

When the connecting means 20 is attached to the center of the gap 3 formed on the side of the module 1, the power supply terminal 16 provided in the opening 13, 14, 15 near the center of the surface of the column 10 in the gap 3, 17 and 18 and the three terminals 23a, 24a, and 25a (or terminals 23b, 24b, and 25b) are in contact with each other and are electrically connected.
When another module is attached to the connection means 20 attached to the module 1, the two modules are structurally connected via the connection means 20. The two modules are also electrically connected by terminals provided in the connecting means 20. At this time, the structural connection is maintained by the strength of the resin material constituting the connecting means 20, and the electrical connection is performed by a metal material that does not contribute to the structural engagement. Further, the terminals 23, 24, and 25 are brought into pressure contact with the power supply terminals 16, 17, and 18 with elasticity by the elasticity or mechanism (not shown) of the material itself. A stable connection state can be maintained even if there is some variation.

  FIG. 5B is an external view of the holding means 21 used when two modules are coupled. The holding means 21 has an elongated connecting rod 26 and connecting portions 27 provided at both ends of the connecting rod. The coupling portion 27 is formed so as to be coupled to the side portion of the module 1 by being inserted into the gap 3 provided in the side portion of the module 1 like the bulging portion 22 of the connecting means 20 described above. It has been done. Further, in the present embodiment, the connecting rod 26 and the coupling portion 27 are integrally formed of a synthetic resin, and each portion is selected in accordance with the material to be used so that it has a strength that is difficult to be deformed by pulling in the longitudinal direction. The size and thickness are set.

FIG. 6 shows the power supply means 28. The power supply means 28 has a main body portion 30 formed with a mounting portion 29 to be inserted into the gap 3 of the module at the side edge. The mounting portion 29 is a portion having the same cross section as the bulging portion 22 of the connecting means 20 described above, and can be mounted on the side portion of the module 1 by this shape.
A power supply power cable 31 is fixedly or detachably connected to the main body 30, and a direct current of about 12 V is supplied via the power cable 31. In addition, three power feeding terminals 32, 33, and 34 that protrude with elasticity are provided side by side on the surface of the mounting portion 29. The arrangement of the terminals coincides with the arrangement of the power supply terminals 16, 17, and 18 provided on the surface portion of the support column 10, and both are brought into contact with each other when the mounting portion 29 is attached.
The feeding terminal of the mounting portion 29 is a means for transmitting the power fed by the power cable 31 to the module 1. The terminals 32 and 34 at both ends are (−) poles, and the terminal 33 at the center is (+). Polar power is supplied.
When electric power is supplied by the power supply means 28, the electric power is transmitted to the respective substrates 12 connected in a lattice shape inside the module 1 so that the light emitters 11 provided on the respective substrates 12 emit light. It has become.

FIG. 7 is an explanatory diagram showing a state in which a plurality of modules are connected. As an example, seven modules (1a, 1b, 1c, 1d, 1e, 1f, 1g) are connected.
Two modules 1a and 1b are arranged at the lowest part in contact with the floor with a space for one, and the lower side of module 1c is connected to the two upper side parts of these two modules 1a and 1b facing each other. ing. The connection means 20 described above is used for this connection.
The module 1d is connected to the upper side of the module 1c connected to the upper sides of the modules 1a and 1b, and the module 1e is connected to the upper side of the module 1d. Connection means 20 is used for coupling the side portions of the modules. Hereinafter, similarly, the connection means 20 is used for all the connection between the side portions.

The module 1d is connected to the upper side portion of the module 1c, and has a shape floating in the space with a space for one module left in the region directly above the module 1b. Further, one end of the holding means 21 is attached to the upper side portion of the module 1d on the side using the connecting means 20, and the other end of the holding means 21 is attached to an upper end edge that is not used for coupling the module 1c below. That is, the module 1d counteracts the moment that opposes the rotational force around the mounting portion of the connecting means 20 about which the module 1d tries to rotate downward by the tension acting on the holding means 21, thereby preventing the module 1d from rotating. ing. In this example, the two holding means 21 are arranged evenly across the connecting means 20 so that the module 1d is not inclined and twisted with respect to the connecting means 20.
The module 1e is connected to the upper side of the module 1d and floats in the space. Then, one end of the holding means 21 is attached to the upper side of the module 1e on the side where the connecting means 20 is attached, and the other end of the holding means 21 is attached to the upper end edge that is not used to connect the module 1d below. Thereby, the moment which opposes the force which the module 1e tries to rotate downward is canceled by the tension | tensile_strength which acts on the holding means 21, and rotation of the module 1e is prevented.

Further, the module 1f is coupled to the upper side of the module 1a that is 90 degrees different from the direction coupled to the module 1c by using the connecting means 20. In this way, when two modules are connected in directions different by 90 degrees, the vertical sides of the two modules come close to each other. In the example shown in FIG. 6, the vertical side portions of the module 1 f and the module 1 c are close to each other. In this case, the adjacent side portions are coupled by the connecting means 20.
In addition, since the module 1f projects into the space without being supported, one end of the holding means 21 is attached to the upper side of the module 1f, and the other end of the holding means 21 is not used for connection. It is attached to the edge to prevent the module 1f from falling.
Since one side of the module 1f in the vertical direction is fixed to the module 1c via the connecting means 20, the same effect as that provided by the holding means 21 is exhibited. Therefore, the holding means 21 is not provided on the side connected to the module 1c, and the holding means 21 is provided only in the vicinity of the end portions spaced apart from each other.

  Further, the module 1g is coupled to the upper side of the module 1f using the connecting means 20. In this case, since the module 1g protrudes into the space without being supported, one end of the holding means 21 is attached to the upper side of the module 1g and the other end is attached to the upper edge of the module 1f to prevent the module 1g from falling down. doing. Further, in this case, the two holding means 21 are arranged evenly on the left and right sides to prevent torsion and uneven load generated in the module 1g and the connecting means 20.

  The module 1 described above is not coupled by simple stacking in the vertical direction, but is coupled so that all surfaces are exposed by connecting the side portions that are the corner edges. Therefore, the shape of the shaped object formed by the connection is not simplified, and various types of lighting devices can be made according to preference. In addition, when light is emitted by energizing the module, light is emitted from all surfaces of all modules except the bottom, so that the decorative effect by light is high along with the degree of freedom in shape. A modeled object can be formed.

FIG. 8 is an explanatory diagram relating to another example of a module. The module 50 (50a, 50b, 50c, 50d, 50e) shown in FIG. 8 is a hexagonal columnar module in which the upper surface and the bottom surface are formed in a regular hexagon and each side surface is formed in a square.

Actually, like the module 1 described above, a column for forming a hexagonal column therein, two hexagonal panels attached to the column, and A substrate having six rectangular panels and a light-emitting body attached to the inner surface of each column is provided. Each substrate is electrically connected in the same manner as the substrate 12 described above.
In addition, in the case of a module formed in a hexagonal column shape, a portion to be connected to another module is an edge portion of the upper surface or the lower surface, and a gap similar to the gap 3 described above is formed in the portion. In addition, three power supply terminals similar to the power supply terminals 16, 17, and 18 are provided inside the gap, and the modules 50 are mechanically and electrically connected to each other using the connection means 20. ing.

  Further, a holding means 51 similar to the holding means 21 described above is provided to prevent the modules from collapsing. The holding means 51 shown in FIG. 8 is simply shown, and has a portion that engages with the gap as in the case of the holding means 21 described above, and has a strength that can withstand a predetermined load. It is formed as follows.

FIG. 9 is an explanatory diagram regarding still another example of the module. The module 60 (60a, 60b, 60c, 60d, 60e, 60f, 60g) shown in FIG. 9 is a triangular column-shaped module in which the upper surface and the bottom surface are formed in a regular triangle and each side surface is formed in a square.
The figure is a concise representation of the module 60. Actually, like the module 1 described above, a column for forming a triangular prism inside, two triangular panels attached to the column, and A substrate having three rectangular panels and a light-emitting body attached to the inner surface of each column is provided. Each substrate is electrically connected in the same manner as the substrate 12 described above.
In the case of a module formed in the shape of a triangular prism, a portion to be connected to another module is an edge portion of the upper surface or the lower surface, and a gap similar to the gap 3 described above is formed in the portion. In addition, three power supply terminals similar to the power supply terminals 16, 17, and 18 are provided inside the gap, and the modules 60 are mechanically and electrically connected to each other using the connection means 20. ing.

  Further, a holding means 61 similar to the holding means 21 described above is provided to prevent the modules from collapsing. Note that the holding means 61 shown in FIG. 9 is simply shown, and is formed so as to have a strength to withstand a predetermined load and a portion that engages with the gap, like the holding means 21 described above. It has been done. Further, the lower end of the holding means 61 has an appropriate structure so that it can be coupled to the apex portion of the triangle.

  The various types of modules described above are provided with structural and electrical connections on the side portions. And as an electrical connection part, the electrode part arranged in equal intervals in the order of negative positive / negative or positive / negative positive is provided. Thereby, when joining the side which provided the connection part of the module, both can be connected, without an electrical polarity reversing by the direction of a module. Thus, according to the present invention, modules can be connected without being aware of the polarity of the electrodes.

In addition, the various types of modules described above can be used in various forms (illumination devices) while being expanded in the horizontal (diagonally upward) direction, rather than simply being stacked, by connecting a single module or a plurality of modules. It can be formed.
Moreover, each module can be exposed without hiding all surfaces except for the lowermost module which also serves as an installation section. As a result, when each module is caused to emit light, light is emitted from all surfaces, so that it has not only a beautiful appearance as a modeled object but also an excellent aesthetic appearance as a lighting device.
Further, the power supply means for supplying power can be attached at any position as long as it is a side portion provided with a power supply terminal on the module. Therefore, it can be attached to a position that does not get in the way from an aesthetic point of view.
The power for light emission is
