[0027] <<<<Overview of this embodiment>>>>

[0028] <<<First Form>>>

[0029] The purpose of the polyhedral structure of the first embodiment is to have a simple structure and to facilitate operation.

[0030] According to the first feature, there is provided a polyhedral structure, wherein:

[0031] The polyhedral structure comprises:

[0032] A base (eg, base 100 described later) extending along an axis (eg, axis AX described later) and having a first pattern conductor (eg, first pattern conductor 150 described later) formed along a surface thereof; and

[0033] A polyhedral portion (such as the polyhedral portion 200 described later, etc.) is connected to the end of the base along the axis (such as the front end portion 102 described later, etc.), and has a plurality of planar portions (such as the polygonal planar portions 212-1A to 212-1E, 212-2A to 212-2E, 212-3A to 212-3E, etc. described later), and a second pattern conductor (such as the second pattern conductor 300 described later, etc.) electrically connected to the first pattern conductor is formed along the surface of each of the plurality of planar portions, and the plurality of planar portions respectively have a polygonal shape.

[0034] The first pattern conductor is formed along the surface of the base. It is not necessary to provide the first pattern conductor inside the base, and the base can be made into a simple structure. In addition, since the first pattern conductor is formed on the surface of the base, even if there is a situation where other devices or components such as an external power supply are electrically connected to the first pattern conductor, it is possible to simplify assembly operations such as connection.

[0035] The second pattern conductor is formed along the surface of the polyhedron. It is not necessary to provide the second pattern conductor inside the polyhedron, and the polyhedron can be made into a simple structure. In addition, since the second pattern conductor is formed on the surface of the polyhedron, even if there is a situation that other parts and devices such as electronic parts are electrically connected to the second pattern conductor, it is possible to simplify assembly operations such as connection.

[0036] The polyhedron part is connected to the base to form an integral body. Since the polyhedron part is connected to the base, the polyhedron part and the base do not need to be managed separately, and the operation of connecting the polyhedron part to the base is not required. By configuring in this way, the polyhedron structure can be made into a simple structure, so that the handling of the polyhedron structure can be simplified.

[0037] The second pattern conductor is electrically connected to the first pattern conductor in advance. Therefore, the operation of electrically connecting the second pattern conductor to the first pattern conductor can be omitted. Therefore, by electrically connecting the first pattern conductor of the base to a power source, etc., power can be supplied to the first pattern conductor, and power can also be directly supplied to the second pattern conductor of the polyhedron portion. The polyhedron portion and the base are integrated, and the first pattern conductor and the second pattern conductor are electrically connected. Therefore, by installing the base on a power source, etc., the entirety of the polyhedron portion and the base can be arranged at a certain position, and the pattern conductors of both the first pattern conductor and the second pattern conductor can be electrically connected to a power source, etc., which can simplify the handling and assembly of the polyhedron structure.

[0038] According to the polyhedral structure of the first form, it is not necessary to provide conductor wiring inside the base and inside the polyhedral part, so that a simple structure can be provided. In addition, according to the polyhedral structure of the first form, it is possible to easily and simply join electronic components and electrically connect to an external power source, so that the assembly operation of the polyhedral structure can be simplified.

[0039] <<<Second Form>>>

[0040] The purpose of the polyhedral structure of the second embodiment is to simplify the work of electrical connection.

[0041] The second feature is based on the first feature, wherein:

[0042] The second pattern conductor has a connection terminal portion (for example, a connection terminal portion 310 described later) for electrical connection with an electronic component on at least one of the plurality of planar portions.

[0043] The second pattern conductor has a connection terminal portion. The connection terminal portion is a conductor portion used to form an electrical connection with other components and devices such as electronic components. The terminal portion of the electronic component can be electrically connected to the connection terminal portion by soldering or the like. Power can be supplied to the electronic component or various signals can be sent and received via the second pattern conductor.

[0044] The connection terminal portion is formed on at least part of the planar portion of the plurality of planar portions. Specifically, the connection terminal portion is formed on the surface of at least part of the planar portion. Other components and devices such as electronic components can be easily connected. According to the second embodiment of the polyhedral structure, the electrical connection operation can be simplified.

[0045] The connection terminal portion may be formed on all of the plurality of plane portions, or may be formed on only one plane portion. The number of plane portions on which the connection terminal portion is provided may be appropriately determined according to the purpose of the polyhedral structure, the size, shape, type, etc. of the electronic component, etc. In addition, more than one connection terminal portion may be provided on one plane portion. The number of connection terminal portions provided on one plane portion may be appropriately determined according to the size, shape, type, etc. of the electronic component, etc.

[0046] <<<Third Form>>>

[0047] The purpose of the polyhedral structure of the third embodiment is to simplify the structure and provide a structure that is easy to manufacture.

[0048] The third feature is based on the first or second feature, wherein:

[0049] A connection region where the base and the polyhedral portion are connected (eg, the back portion 220 and the boundary portion 250 described later) includes a plane extending in a direction perpendicular to the axis (eg, the imaginary plane IP2 described later).

[0050] The polyhedral structure has a connection region where the base and the polyhedral portion are connected. The base and the polyhedral portion are connected in advance, and the polyhedral structure has an integrated structure.

[0051] The connecting region includes a plane extending in a direction perpendicular to the axis. That is, the connecting region extends in a direction perpendicular to the axis. For example, the connecting region extends in a direction perpendicular to the length direction of the base. The connecting region between the base and the polyhedral portion can be formed by a single plane, making the structure of the polyhedral structure simple and providing a structure that is easy to manufacture.

[0052] In addition, the base and the polyhedron may be detachably formed instead of being integral. By making the base and the polyhedron separately, efficiency can be improved.

[0053] <<<Fourth Form>>>

[0054] The purpose of the fourth embodiment of the polyhedral structure is to make the characteristics and functions exerted in the plane portion of the polyhedral portion different along the direction of the axis. For example, the purpose is to make the directivity of the wave different along the direction of the axis in the case of a structure in which a wave is emitted from the plane portion of the polyhedral structure.

[0055] The fourth feature is based on the first to third features, wherein:

[0056] In the polyhedral portion, an imaginary plane (such as the imaginary plane IP1 described later, etc.) formed by at least three boundary line portions (such as the boundary line portions 230A to 230E described later, etc.) surrounding the axis among the boundary line portions (such as the boundary line portions 230A to 230E, the boundary line portions 250A to 250E described later, etc.) formed between the planar portions adjacent to each other is a flat surface (such as the boundary portion 230 described later, etc.) extending in a direction perpendicular to the axis.

[0057] A boundary line portion is formed between adjacent planar portions among the plurality of planar portions of the polyhedral portion. In the polyhedral portion, if the planar portions are adjacent, a boundary line portion is inevitably formed between them. Therefore, the polyhedral portion has a plurality of boundary line portions.

[0058] Some of the boundary line portions connected to each other among the plurality of boundary line portions of the polyhedral portion surround the axis. The boundary line portions surrounding the axis constitute the boundary portion (dividing interface). There are at least three boundary line portions surrounding the axis. The number of boundary line portions constituting the boundary portion may also be more than three. The number of boundary line portions surrounding the axis can be appropriately determined according to the shapes of the polyhedral portion and the planar portion, etc.

[0059] An imaginary plane can be formed by at least three dividing line portions surrounding the axis. An imaginary plane is a flat surface extending in a direction perpendicular to the axis. In addition, the imaginary plane only needs to intersect the axis and may not extend in a direction perpendicular to the axis. An imaginary plane only needs to be a plane that can virtually divide the polyhedron into several regions.

[0060] The polyhedron portion can be divided into at least two regions along the axis with an imaginary plane as a reference. That is, the polyhedron portion can be divided into two regions along the axis, namely, a region on the side farther from the base and a region on the side closer to the base (e.g., the front polyhedron portion 210a, the rear polyhedron portion 210b, etc. described later), with an imaginary plane as a reference. Moreover, the multiple planar portions of the polyhedron portion can be divided into a planar portion belonging to the region on the farther side and a planar portion belonging to the region on the closer side. Moreover, for example, the polyhedron portion can be constructed so that the direction in which the planar portion of the region on the farther side faces is different from the direction in which the planar portion of the region on the closer side faces. By constructing in this way, the characteristics and functions exerted by the planar portion on the side farther from the base can be different from the characteristics and functions exerted by the planar portion on the side closer to the base along the axis.

[0061] More specifically, for example, a component, part, device, etc. that emits waves can be provided on the plane portion of the polyhedron portion. A component that emits waves in a direction away from the base along the axis can be provided on the plane portion located on the side farther from the base along the axis. On the other hand, a component that emits waves in a direction close to the base along the axis can be provided on the plane portion located on the side closer to the base along the axis. By configuring in this way, the directivity and diffusivity of the waves emitted from the polyhedron structure can be made different depending on the direction along the axis.

[0062] In addition, not only components for emitting waves but also components for receiving waves may be provided on the plane portion of the polyhedron. In addition, components for emitting waves and components for receiving waves may be provided in a mixed manner on the plane portion of the polyhedron.

[0063] In addition, the imaginary plane may be not only one but also multiple. Therefore, the polyhedron portion may be divided into three or more regions by multiple imaginary planes. The characteristics and functions exerted by the plane portions contained in each of the three or more regions of the polyhedron portion are made different from each other, so that various characteristics and functions can be exerted for each region.

[0064] <<<Fifth Form>>>

[0065] The purpose of the polyhedral structure of the fifth aspect is to determine the characteristics and functions to be exerted based on the direction of the normal line of the plane portion of the polyhedral portion. For example, the purpose is to determine the directivity of the wave emitted from the plane portion of the polyhedral portion.

[0066] The fifth aspect is based on the first to fourth features, wherein:

[0067] A first region of the polyhedron portion that is farther from the base portion than the imaginary plane (e.g., a front polyhedron portion 210a described later) has at least three first plane portions (e.g., polygonal plane portions 212-1A to 212-1E described later) having first normal lines (e.g., normal lines n1A to n1E described later) among the plane portions constituting the polyhedron portion,

[0068] The first normal lines of the at least three first planar portions are oriented in different directions from each other.

[0069] For each of the at least three first planar portions, the angle formed by the first normal line and the axis is a first angle (eg, angle θ1 described later).

[0070] The first region is a region of a portion of the polyhedral portion that is farther from the base portion than the imaginary plane. At least three first plane portions belonging to the first region have a first normal line.

[0071] The directions of the first normal lines of at least three first planar portions are different from each other. The angles formed by the first normal lines of at least three first planar portions and the axis are the same first angles. That is, the directions of the first normal lines of the first planar portions themselves are different from each other, but the angles formed by them and the axis are the same.

[0072] The characteristics and functions exerted by the plane portion can be determined according to the direction of the normal line of the plane portion. In addition, in the first region, since the angle formed by the first normal line of the plane portion and the axis is the same first angle, it is easy to make the characteristics and functions exerted by the plane portion belonging to the first region consistent. For example, for the plane portion belonging to the first region, the characteristics such as the degree of divergence and the degree of dispersion relative to the axis can be made consistent.

[0073] <<<Sixth Form>>>

[0074] The purpose of the polyhedral structure of the sixth aspect is to make it easy to unify the characteristics and functions exerted in the planar portion of the polyhedral portion.

[0075] The sixth aspect is based on the first to fifth aspects, wherein:

[0076] The at least three first planar portions surround the axis.

[0077] By utilizing the rotational symmetry about the axis, it is possible to easily unify the characteristics and functions exhibited by the planar portion of the polyhedral portion.

[0078] <<<Seventh Form>>>

[0079] The seventh embodiment of the polyhedral structure aims to determine the characteristics and functions to be exerted based on the direction of the normal line of the plane portion of the polyhedral portion, and also aims to make the characteristics and functions to be exerted consistent according to the region to which the plane portion belongs.

[0080] The seventh aspect is based on the first to fifth aspects, wherein:

[0081] A second region of the polyhedron portion closer to the base portion than the imaginary plane (e.g., a rear polyhedron portion 210b described later) has at least three second plane portions having a second normal (e.g., a polygonal plane portion 212-2A to 212-2E described later) and at least three third plane portions having a third normal (e.g., a polygonal plane portion 212-3A to 212-3E described later) among the plane portions constituting the polyhedron portion.

[0082] The second normal lines (such as normal lines n2A to n2E described later) of the at least three second planar portions are oriented in different directions from each other.

[0083] The third normal lines (such as normal lines n3A to n3E described later) of the at least three third planar portions are oriented in different directions from each other.

[0084] A second angle (eg, angle θ2 described below) formed by the second normal line and the axis line is not equal to a third angle (eg, angle θ3 described below) formed by the third normal line and the axis line.

[0085] The second region of the polyhedral portion closer to the base has a second plane portion and a third plane portion. The second plane portion has a second normal line. The third plane portion has a third normal line. The second angle formed by the second normal line and the axis line is not equal to the third angle formed by the third normal line and the axis line.

[0086] The second region includes the second plane portion having the second normal line and the third plane portion having the third normal line, so the characteristics and functions exerted in the plane portion can be determined according to the direction of the normal line of the plane portion. Moreover, the characteristics and functions exerted can be made consistent based on the region to which the plane portion having the second angle belongs, and the characteristics and functions exerted can be made consistent based on the region to which the plane portion having the third angle belongs.

[0087] <<<Eighth Form>>>

[0088] The purpose of the polyhedral structure of the eighth aspect is to make it easy to unify the characteristics and functions exerted in the planar portion of the polyhedral portion.

[0089] The eighth aspect is based on the first to seventh aspects, wherein:

[0090] The at least three second planar portions and the at least three third planar portions surround the axis.

[0091] By utilizing the rotational symmetry about the axis, it is possible to easily unify the characteristics and functions exhibited by the planar portion of the polyhedral portion.

[0092] The second plane portion and the third plane portion are alternately arranged around the axis. That is, the second plane portion and the third plane portion are alternately arranged around the axis to surround the axis. In addition, the second plane portion and the third plane portion do not exist in the first region. The second plane portion and the third plane portion exist in a region of the polyhedral portion that is closer to the base than the first region and farther from the base than the imaginary plane.

[0093] <<<9th Form>>>

[0094] The purpose of the polyhedral structure of the ninth aspect is to make it easy to unify the characteristics and functions exerted by the planar portion of the polyhedral portion.

[0095] The ninth aspect is based on the first to seventh aspects, wherein:

[0096] The second angle and the third angle are not equal to the first angle.

[0097] The characteristics and functions exhibited by the planar portion of the polyhedral portion can be easily aligned on the axis.

[0098] <<<10th Form>>>

[0099] The purpose of the polyhedral structure of the tenth form is to have a simple structure and to facilitate operation.

[0100] The tenth aspect is based on the first to fifth aspects, wherein:

[0101] The second pattern conductor has:

[0102] a gathering pattern (such as the gathering pattern 320 described later) electrically connected to at least a portion of the connection terminal portion formed on the first planar portion; and

[0103] A guide pattern (eg, a guide pattern 330 described later) electrically connects the cluster pattern and the first pattern conductor.

[0104] The second pattern conductor has a clustering pattern and a guide pattern.

[0105] The clustered pattern is electrically connected to at least a portion of the connecting terminal portion. In the case where the second pattern conductor has a plurality of connecting terminal portions, the clustered pattern can gather the plurality of connecting terminal portions together to form an electrical connection. Therefore, it is possible to form an electrical connection without separately forming a pattern conductor for each of the plurality of connecting terminal portions. By reducing the number of pattern conductors to be formed on the planar portion of the polyhedron portion, the structure of the polyhedron portion can be simplified. Moreover, by reducing the occupied area of ​​the pattern conductors to be formed on the planar portion of the polyhedron portion, the planar portion of the polyhedron portion can be effectively utilized, thereby increasing the number of electronic components that can be mounted.

[0106] The guide pattern electrically connects the cluster pattern to the first pattern conductor. As described above, the cluster pattern is used to aggregate the plurality of connection terminal portions, and the guide pattern does not need to be formed separately for each of the plurality of connection terminal portions. As long as a small area can be ensured, the guide pattern can be formed and electrically connected to the first pattern conductor. Thus, the structure of the polyhedron portion can be simplified, and the planar portion of the polyhedron portion can be effectively utilized.

[0107] <<<11th Form>>>

[0108] The polyhedral structure of the eleventh aspect aims to increase the degree of freedom in arrangement of the second pattern conductors in the polyhedral portion.

[0109] The eleventh aspect is based on the first to tenth aspects, wherein:

[0110] The clustered pattern is a pattern conductor formed at a position farthest from the base portion among the second pattern conductors.

[0111] Since the clustered pattern is formed at the position farthest from the base, the second pattern conductor formed on the plane portion of the polyhedron can be arranged, sized, shaped, etc. with greater freedom. In addition, the clustered pattern can be formed without interfering with the connection terminal portion.

[0189] <Back surface portion 220, boundary portion 250, virtual plane IP2>

[0190] The back portion 220 is located at the rear side of the polyhedron portion 200. The back portion 220 has a substantially flat shape of a substantially pentagonal shape. In addition, the back portion 220 has a notch 290 described later, but has a flat shape as a whole.

[0194] <Normal lines n1A to n1E (n1), n2A to n2E (n2), n3A to n3E (n3)>

[0195] Figure 62 is a diagram showing the appearance of the polyhedral structure 10 as viewed from a direction parallel to the polygonal plane portion 212-1 and the polygonal plane portion 212-2. In this state, the normal lines n1A and n2A and the axis line AX are included in the same plane. Figure 6 The figure shows the appearance of the polyhedral structure 10 viewed from a direction perpendicular to a plane including normal lines n1A, n2A and the axis AX. The polygonal planar portion 212-1A and the polygonal planar portion 212-2A extend in a direction perpendicular to the plane including normal lines n1A, n2A and the axis AX.

[0196] Figure 7 21 - 3 is a diagram showing the appearance of the polyhedral structure 10 along a plane parallel to the polygonal plane portion 212 - 3. In this state, the normal line n3A and the axis line AX are included in the same plane. Figure 7 2 is a diagram showing the appearance of the polyhedral structure 10 as viewed from a direction perpendicular to a plane including the normal line n3A and the axis line AX. The polygonal planar portion 212-3A extends in a direction perpendicular to the plane including the normal line n3A and the axis line AX.

[0197] Figure 8 This is a diagram showing a state where three normal lines n1, n2, and n3 are virtually arranged in the same plane. Figure 8 The three normal lines n1, n2, and n3 are represented so that their starting points coincide with each other on the axis AX.

[0198] The polygonal planar portions 212-1A, 212-1B, 212-1C, 212-1D, and 212-1E of the front polygonal surface portion 210a face different directions from each other, and the directions of the normal lines n1A, n1B, n1C, n1D, and n1E are different from each other.

[0199] The polygonal planar portions 212-2A, 212-2B, 212-2C, 212-2D, and 212-2E of the rear polygonal surface portion 210b face different directions from each other, and the directions of the normal lines n2A, n2B, n2C, n2D, and n2E are different from each other.

[0200] The polygonal planar portions 212-3A, 212-3B, 212-3C, 212-3D, and 212-3E of the rear polygonal surface portion 210b face different directions from each other, and the directions of the normal lines n3A, n3B, n3C, n3D, and n3E are different from each other.

[0201] Furthermore, the directions of normal lines n1A to n1E, the directions of normal lines n2A to n2E, and the directions of normal lines n3A to n3E are different from each other.

[0202] As described above, the directions of the normal lines n1A, n1B, n1C, n1D, and n1E are different from each other. However, the angles formed by the normal lines n1A, n1B, n1C, n1D, and n1E with the axis AX are the same. In other words, the normal lines n1A, n1B, n1C, n1D, and n1E have rotational symmetry centered on the axis AX. Figure 8 As shown, the normal lines n1A to n1E have an angle θ1 with respect to the axis AX. The polygonal plane parts 212-1A to 212-1E of the front multi-face part 210a respectively have normal lines n1A to n1E, and the angles formed by the normal lines n1A to n1E and the axis AX are the same angle θ1. In addition, in this embodiment, there are two cases where θ1 is used as a symbol for identifying an angle and a case where it is used as a symbol for indicating the size of an angle.

[0203] The polygonal plane parts 212-1A, 212-1B, 212-1C, 212-1D, and 212-1E of the front polygonal surface part 210a face the direction of angle θ1 with respect to the axis AX. Therefore, the directions of the polygonal plane parts 212-1A to 212-1E can be made consistent. For example, when LEDs 400 are provided on the polygonal plane parts 212-1A to 212-1E, the degree of divergence and dispersion with respect to the axis AX can be made consistent to emit light. In this case, light that faces forward and diverges can be emitted.

[0204] Likewise, the directions of the normals n2A, n2B, n2C, n2D, n2E are different from each other. However, the angles formed by the normals n2A, n2B, n2C, n2D, n2E and the axis AX are the same. The normals n2A, n2B, n2C, n2D, n2E have rotational symmetry centered on the axis AX. Figure 8 As shown, the normal lines n2A to n2E have an angle θ2 with respect to the axis AX. The angle θ2 is larger than the angle θ1. The polygonal plane parts 212-2A to 212-2E of the rear multi-face part 210b respectively have normal lines n2A to n2E, and the angle formed by the normal lines n2A to n2E and the axis AX is the same angle θ2. In addition, in this embodiment, there are two cases where θ2 is used as a symbol for identifying an angle and a case where it is used as a symbol for indicating the size of an angle.

[0205] The polygonal plane parts 212-2A, 212-2B, 212-2C, 212-2D, and 212-2E of the rear polygonal surface part 210b face the direction of angle θ2 with respect to the axis AX. Therefore, the directions of the polygonal plane parts 212-2A to 212-2E can be made consistent. For example, when LEDs 400 are provided on the polygonal plane parts 212-2A to 212-2E, the degree of divergence and dispersion with respect to the axis AX can be made consistent to emit light. In this case, light that faces forward and diverges is emitted. In addition, light that is easier to diverge to the side than the aforementioned polygonal plane parts 212-2A to 212-2E is emitted.

[0206] Furthermore, the polygonal planar portions 212-2A to 212-2E are different from the polygonal planar portions 212-1A to 212-1E and face in the direction of angle θ2 with respect to the axis AX. Therefore, the degree of divergence and dispersion with respect to the axis AX can be made different from those of the polygonal planar portions 212-1A to 212-1E.

[0207] Moreover, the directions of the normal lines n3A, n3B, n3C, n3D, and n3E are different from each other. However, the angles formed by the normal lines n3A, n3B, n3C, n3D, and n3E with the axis AX are the same. The normal lines n3A, n3B, n3C, n3D, and n3E have rotational symmetry centered on the axis AX. Figure 8 As shown, the normal lines n3A to n3E have an angle θ3 with respect to the axis AX. The angle θ3 is larger than the angle θ2. The polygonal plane parts 212A to 212E of the rear multi-face part 210b have normal lines n3A to n3E, respectively, and the angles formed by the normal lines n3A to n3E and the axis AX are the same angle θ3. In addition, in this embodiment, there are two cases where θ3 is used as a symbol for identifying an angle and a case where it is used as a symbol for indicating the size of an angle.

[0208] The polygonal plane parts 212-3A, 212-3B, 212-3C, 212-3D, and 212-3E of the rear polygonal surface part 210b face the direction of angle θ3 with respect to the axis AX. Therefore, the directions of the polygonal plane parts 212-3A to 212-3E can be made consistent. For example, when LEDs 400 are provided on the polygonal plane parts 212A to 212E, the degree of divergence and dispersion with respect to the axis AX can be made consistent to emit light. In this case, light is emitted that diverges toward the rear and to the side.

[0209] Furthermore, the polygonal plane portions 212-3A to 212-3E are different from the polygonal plane portions 212-1A to 212-1E and the polygonal plane portions 212-2A to 212-2E and face the direction of the angle θ3 with respect to the axis AX. Therefore, the degree of divergence and dispersion with respect to the axis AX can be made different from those of the polygonal plane portions 212-1A to 212-1E and the polygonal plane portions 212-2A to 212-2E.

[0210] <Direction and Divergence of Light>

[0211] As described above, the front multi-faceted surface 210a has only the polygonal planar surfaces 212-1A to 212-1E. In the front multi-faceted surface 210a, light can be formed to diverge at an angle θ1 relative to the front (the +X direction of the axis AX). The angle θ1 is an acute angle (see Figure 6 and Figure 8 ). The front multi-faceted portion 210a can form light that is directed forward and divergent.

[0212] In addition, the rear multi-faceted portion 210b has multi-sided plane portions 212-2A to 212-2E and multi-sided plane portions 212-3A to 212-3E. In this way, light can be formed to be diverged at an angle θ2 greater than angle θ1 and an angle θ3 greater than angle θ2 relative to the front (+X direction of axis AX). Angle θ2 is greater than angle θ1, but is an acute angle (see Figure 6 and Figure 8 ). Angle θ3 is an obtuse angle (refer to Figure 7 and Figure 8 ). That is, the rear multi-faceted surface 210b can form light that is divergent toward the side (in a direction perpendicular to the axis AX) compared to the front multi-faceted surface 210a.

[0213] The polygonal plane portions 212-2A to 212E form light that is directed forward and divergent laterally, and the polygonal plane portions 212-3A to 212E form light that is directed backward and divergent laterally. The rear polygonal surface portion 210b can form light that is divergent in mutually different lateral directions.

[0214] In the above example, the front multi-faceted portion 210a has only the polygonal plane portions 212-1A to 212-1E whose normal direction is at an angle θ1 with respect to the axis AX, but the present invention is not limited thereto. The front multi-faceted portion 210a may also be provided with polygonal plane portions that form multiple angles with respect to the front (axis AX). The light propagation mode and divergence mode can be set according to the application, etc.

[0215] In addition, in the above-mentioned example, the rear polygonal surface 210b has a structure of two polygonal plane portions, namely, polygonal plane portions 212-2A to 212-2E whose normal direction is at an angle θ2 relative to the axis AX and polygonal plane portions 212-3A to 212-3E whose normal direction is at an angle θ3 relative to the axis AX, but the present invention is not limited thereto. The rear polygonal surface 210b may also be provided with a polygonal plane portion having a normal line that forms three or more different angles relative to the front (axis AX). The light travel mode and divergence mode can be set according to the application, etc.

[0216] Furthermore, the five polygonal plane portions 212-2A, 212-2B, 212-2C, 212-2D, 212-2E and the five polygonal plane portions 212-3A, 212-3B, 212-3C, 212-3D, 212-3E are arranged alternately around the axis AX. In this way, the form of light emitted from the five polygonal plane portions 212-2A, 212-2B, 212-2C, 212-2D, 212-2E and diverging around the axis AX can be easily made consistent with the form of light emitted from the five polygonal plane portions 212-3A, 212-3B, 212-3C, 212-3D, 212-3E and diverging around the axis AX, thereby reducing uneven brightness in the entire circumferential direction.

[0217] <Hole 280 and notch 290>

[0218] The polyhedral portion 200 may also have holes 280 and notches 290. The holes 280 and notches 290 increase the surface area of ​​the polyhedral portion 200. The holes 280 and notches 290 facilitate heat dissipation from electronic components such as the LED 400. The depth, diameter, number, and position of the holes 280 and notches 290 may be appropriately determined according to the size, shape, and type of the electronic components mounted, the size and shape of the connection terminal portion 310 described later, and the like.

[0219] <<Second Pattern Conductor 300>>

[0220] The polyhedron portion 200 includes a second pattern conductor 300 . The second guide pattern 300 includes a connection terminal portion 310 , a gathering pattern 320 , a guide pattern 330 , and a back surface pattern 340 .

[0221] <Connection terminal portion 310 >

[0222] The connection terminal portion 310 is formed on each of the polygonal plane portions 212-1A to 212-1E of the front polygonal portion 210a, each of the polygonal plane portions 212-2A to 212-2E of the rear polygonal portion 210b, and each of the polygonal plane portions 212-3A to 212-3E of the rear polygonal portion 210b.

[0223] The connection terminal portion 310 is electrically connected to a terminal (not shown) of the LED 400, similarly to the base terminal portion 156 (see Fig. 9 and Fig.10 ). The connection terminal portion 310 is a pattern conductor for directly supplying power to the LED 400. A set of two connection terminal portions 310 is electrically connected to one LED 400. One of the two connection terminal portions 310 becomes a positive electrode, and the other becomes a negative electrode. The size and position of the connection terminal portion 310 can be appropriately determined according to the size, shape, distance, etc. of the terminal of the LED 400. Power is supplied to the capacitor 500 provided on the base 100 via the connection terminal portion 310.

[0224] The connection terminal portions 310 of two adjacent polygonal plane portions 212-1 and 212-2 are electrically connected via the boundary line portions 230A to 230E. Thus, the LED 400 provided in the polygonal plane portion 212-1 and the LED 400 provided in the polygonal plane portion 212-2 can be connected in series.

[0225] The connection terminal portions 310 of two adjacent polygonal plane portions 212-2 and 212-3 are electrically connected via the boundary portions 240AA, 240AB, 240BB, 240BC, 240CC, 240CD, 240DD, 240DE, 240EE, and 240EA, thereby connecting the LED 400 provided in the polygonal plane portion 212-2 and the LED 400 provided in the polygonal plane portion 212-3 in series.

[0226] The connection terminal portion 310 of the polygonal planar portion 212 - 3 and a rear surface pattern 340 (described later) of the rear surface portion 220 are electrically connected via boundary line portions 250A to 250E.

[0227] <Gathering pattern 320>

[0228] like Figure 1 As shown, the gathering pattern 320 is electrically connected to the connection terminal portion 310 of the polygonal plane portion 212-1A to 212-1E of the front polygonal surface 210a. The gathering pattern 320 has a ring-shaped shape. The gathering pattern 320 is formed on the front polygonal surface 210a. The gathering pattern 320 is formed at the position farthest from the base 100 on the front polygonal surface 210a. The gathering pattern 320 surrounds the axis AX. The gathering pattern 320 is formed across the polygonal plane portions 212-1A to 212-1E. The gathering pattern 320 is electrically connected to the connection terminal portion 310 of the polygonal plane portions 212-1A to 212-1E for each polygonal plane portion 212-1A to 212-1E.

[0229] <Guide pattern 330>

[0230] The guide pattern 330 electrically connects the gathering pattern 320 to the power supply pattern 154. The guide pattern 330 is continuously formed across the polygonal plane portion 212 of the front multi-face portion 210a and the rear multi-face portion 210b. The guide pattern 330 is formed separately from the connection terminal portion 310 in the front multi-face portion 210a and the rear multi-face portion 210b. The guide pattern 330 may be directly electrically connected to the connection terminal portion 310 of the front multi-face portion 210a and the rear multi-face portion 210b, or may be electrically connected via the gathering pattern 320.

[0231] <Back pattern 340>

[0232] The back pattern 340 is formed on the back portion 220. The back pattern 340 is electrically connected to both the connection terminal portion 310 of the polygonal plane portion 212-3 and the base terminal portion 156 of the base 100. Thus, the LED 400 provided on the polygonal plane portion 212-3 and the capacitor 500 provided on the base 100 can be connected in series.

[0233] <<<Connection of LED 400>>>

[0234] The polyhedral structure 10 is equipped with a plurality of LEDs 400. Five LED lines 400 are electrically arranged in parallel in the polyhedral structure 10. One end of the five LED lines 400 is electrically connected to the cluster pattern 320. The other end of the five LED lines 400 is electrically connected to the power supply terminal 152.

[0235] The plurality of LEDs 400 in each LED 400 row are electrically connected in series. In this way, by connecting the plurality of LED 400 rows formed by connecting the plurality of LEDs 400 in series in parallel, the plurality of LEDs 400 can be arranged in the polyhedron portion 200 without deviation and evenly distributed in a manner that can supply power to the plurality of LEDs 400. In addition, by connecting the plurality of LEDs 400 in series, the voltage applied to each LED 400 can be reduced. Therefore, even when the polyhedron structure 10 is used in connection with a high voltage power supply, for example, as an in-vehicle lighting, a low withstand voltage LED 400 can be used, and the range of types that can be used as LEDs 400 can be expanded and the structure can be inexpensive.

[0236] For example, the LED 400 is electrically connected in the manner of power supply terminal portion 152 → base terminal portion 156 → capacitor 500 → base terminal portion 156 → (branched into five lines) → back pattern 340 → connection terminal portion 310 → LED 400 → connection terminal portion 310 →… → connection terminal portion 310 → LED 400 → connection terminal portion 310 → aggregation pattern 320 (gathered into one line) → guide pattern 330 → power supply pattern 154 → power supply terminal portion 152, and power is supplied to the LED 400.

[0237] Thus, the polyhedral structure of the present embodiment including LEDs can be used as various lightings such as decorative lightings such as chandeliers and mirror balls in addition to vehicle-mounted lightings such as turn signals, tail lights, and flashers.

[0238] <<<Modification>>>

[0239] In the above example, an example of emitting light from LED 400 in multiple directions is shown, but in addition to light sources such as LEDs, it is also possible to set a polyhedral structure that can be equipped with a speaker that emits sound, a microphone that receives sound, a camera element that takes images, a display, etc. In other words, the polyhedral structure can provide multi-directional and non-directional characteristics, as long as it is a polyhedral structure related to the propagation of various waves such as light, sound, and electromagnetic waves.
