For example, Patent Literature (PTL) 1 discloses, as this type of a lighting device, a three-dimensional light source that includes a plurality of planar light sources including light-emitting surfaces and is in a standard three-dimensional shape provided by bending one contiguous surface including at least two of the plurality of planar light sources.
[PTL 1] Japanese Unexamined Patent Application Publication No. 2018-142398
However, PTL 1 has difficulty achieving both a reduction of an increase in the number of assembling processes due to an increase in the number of components and an improvement of dust-proofing and moisture barrier properties by preventing gaps between components from being provided.
In view of this, the present disclosure has an object to provide a lighting device capable of achieving both a reduction of an increase in the number of assembling processes and an improvement of dust-proofing and moisture barrier properties.
In order to achieve the above object, a lighting device according to one aspect of the present disclosure is a lighting device capable of illuminating in all direction, the lighting device comprising: a case that includes a plurality of wall portions each including a face in a polygonal shape; a plurality of light-emitting elements that are provided in the plurality of wall portions and emit light toward outside of the lighting device; and a controller that controls the plurality of light-emitting elements separately, wherein the case: is of an outer shape that is spherical or polyhedral; and includes bent portions that are bent in the outer shape of the case, and the bent portions constitute at least three sides of the outer shape of the case.
The lighting device according to the present disclosure is capable of achieving both a reduction of an increase in the number of assembling processes and an improvement of dust-proofing and moisture barrier properties.
Hereinafter, embodiments of the present disclosure are described. It should be noted that the embodiments described below each show a specific example of the present disclosure. Accordingly, the numerical values, constituent elements, the arrangement and connection of the constituent elements, steps and the order of the steps, etc. indicated in the following embodiments are mere examples, and are thus not intended to limit the present disclosure. Therefore, among the constituent elements in the following embodiments, those not recited in the independent claims are described as optional constituent elements.
Moreover, the respective figures are schematic diagrams and are not necessarily accurate illustrations. It should be noted that, in the figures, the same constituent elements are assigned substantially the same reference signs, and overlapping description is omitted or simplified.
Furthermore, terms such as “substantially vertical” and “substantially spherical shape” are used in the following embodiments. For example, “substantially vertical” and “substantially spherical shape” mean not only “completely vertical” and “completely spherical shape,” but also “vertical in effect” and “spherical shape in effect,” so that the meaning includes an error of about several percent, for example. In addition, “substantially vertical” and “substantially spherical shape” mean vertical and a spherical shape in a range in which the present disclosure can achieve advantageous effects. The same applies to other expressions that include “substantially” and “shape.”
Hereinafter, the embodiments are described in detail with reference to the drawings.
The following describes a configuration of lighting device 2 according to the present embodiment.
As shown in
Moreover, lighting device 2 is installed on, for example, a ceiling, a floor, a wall, or a desk in a room of a building. The outer shape of lighting device 2 is spherical or polyhedral. In the present embodiment, the outer shape of lighting device 2 is an icosahedron having twelve vertices. It should be noted that the outer shape of lighting device 2 is not limited to an icosahedron, and may be another polyhedron.
Furthermore, lighting device 2 is a luminaire capable of radiating light (illuminating) in all directions of 360 degrees, and includes the plurality of light sources 11. The plurality of light sources 11 are substantially disposed across lighting device 2. Here, all directions of 360 degrees refer to all directions from the center of lighting device 2 toward any points. To put it another way, lighting device 2 is capable of causing the plurality of light sources 11 to radiate light in all directions, thereby illuminating all directions.
Moreover, by selectively causing at least one light source 11 among the plurality of light sources 11 to emit light, lighting device 2 is capable of radiating light in any direction from lighting device 2 as a center. For example, lighting device 2 is capable of radiating light in all directions of 360 degrees by causing all the plurality of light sources 11 to emit light simultaneously, or is capable of radiating light only in some directions by causing at least one light source 11 among the plurality of light sources 11 to emit light. In other words, lighting device 2 is capable of not only radiating light in all directions of 360 degrees but also radiating light in any direction in the same manner as a spotlight.
Furthermore, lighting device 2 has a dimming control function and a toning control function. Specifically, lighting device 2 is capable of changing a luminance (brightness) and a light color (color temperature or color) of light to be emitted. In the present embodiment, each of the plurality of light sources 11 is capable of changing a light luminance and a light color in lighting device 2.
Moreover, lighting device 2 according to the present embodiment is capable of evenly illuminating an object such as a wall surface with light in full color. For this reason, as described below, each of the plurality of light sources 11 includes a three-color light source of red, green, and blue (RGB).
In addition, the plurality of light sources 11 are evenly and dispersedly disposed at high densities. Accordingly, by controlling light to be radiated, lighting device 2 is capable of producing a space in which lighting device 2 is disposed.
Furthermore, unlike a display that displays an image, since lighting device 2 according to the present embodiment needs to illuminate a wall surface or the like, the plurality of light sources 11 need to produce a high light output. For this reason, a luminance per light source 11 is high compared to a light-emitting diode (LED) light source used for a backlight of a liquid crystal display, or an LED light source used for an LED display.
Moreover, since the plurality of light sources 11 that are high-output light sources and capable of illuminating in all directions are disposed in lighting device 2 according to the present embodiment, it is difficult to provide a heat-dissipating component such as a heat sink in lighting device 2, compared to conventional lighting devices. Furthermore, since lighting device 2 according to the present embodiment is capable of separately controlling all light-emitting elements 11a included in lighting device 2, the amount of heat generation in controller 12 of lighting device 2 increases. In other words, the internal temperature of lighting device 2 is higher than the external temperature of lighting device 2. For this reason, the difference in temperature between the inside and outside of lighting device 2 causes airflow from the outside to inside of lighting device 2 easily. Accordingly, for example, when a case forming an exterior of a lighting device has a gap, dirt, dust, and water vapor enter easily through the gap together with airflow. In view of this, in order to prevent dirt, dust, and water vapor from entering, lighting device 2 includes the following configuration.
Lighting device 2 includes case 5, a plurality of light-transmitting portions 6, a plurality of light sources 11, controller 12, power supply 13, storage 15, and communicator 14.
Case 5 is an exterior cover that is of an outer shape that is spherical or polyhedral. Case 5 includes a plurality of wall portions 5c each of which includes face 50 in a polygonal shape. Here, the polygonal shape is at least one of a triangular shape, a quadrilateral shape, a pentagonal shape, or a hexagonal shape. Moreover, face 50 in the polygonal shape is an outer face of case 5. Furthermore, face 50 in the polygonal shape is a flat face or a curved face.
In the present embodiment, the outer faces of case 5 include twenty triangular faces. In other words, case 5 is an icosahedron having twelve vertices.
It should be noted that the outer shape of case 5 is not limited to an icosahedron. Examples of the outer shape of case 5 include a tetrahedron including triangular faces, a hexahedron including quadrilateral faces, a dodecahedron including pentagonal faces, an icosidodecahedron including pentagonal faces and hexagonal faces, and a snub dodecahedron including triangular faces and pentagonal faces.
Case 5 includes bent portions 5e that are bent in the outer shape of case 5. Bent portions 5e constitute at least three sides of the outer shape of case 5. Specifically, bent portion 5e is a border portion between two adjacent wall portions 5c, and is provided by bending the border portion. Bent portion 5e thus provided connects two adjacent wall portions 5c integrally, and forms one side of the outer shape of case 5.
The following describes a state before the outer shape of case 5 is provided and a state of case 5 when the outer shape of case 5 is provided with reference to
As shown in
As shown in
Moreover, when first tabular component 5b1 is bent for each wall portion 5c, first tabular component 5b1 includes a portion in which first edge portion 51a that is one side of first wall portion 5c1 among the plurality of wall portions 5c is in contact with second edge portion 52a that is one side of second wall portion 5c2 different from first wall portion 5c1 among the plurality of wall portions 5c. For this reason, it is necessary to secure first edge portion 51a and second edge portion 52a by connecting first edge portion 51a and second edge portion 52a.
Here, a case in which first edge portion 51a and second edge portion 52a are connected is described with reference to
As shown in
In the present embodiment, when first edge portion 51a and second edge portion 52a are fit together, engaging portion 51b is a columnar body extending from first edge portion 51a toward engaged portion 52b. Additionally, engaged portion 52b is an insertion portion including an insertion hole into which engaging portion 51b is inserted.
As shown in
Moreover, as shown in
It should be noted that, in the present embodiment, a power supply connector for supplying power to power supply 13 from an external power source, a communication connector for communicating with an external device and terminal device 20, and a connecting portion to which a metal hook serving as an attaching component for attaching lighting device 2 to a ceiling, a wall, or the like are provided on predetermined wall portion 5d1 among the plurality of wall portions 5c. In the present embodiment, light source 11 is not disposed on predetermined wall portion 5d1. It should be noted that light source 11 may be disposed on predetermined wall portion 5d1.
Furthermore, as shown in
Moreover, case 5 according to the present embodiment contains a resin material such as polycarbonate, acrylonitrile butadiene styrene (ABS), and polycarbonate (PC). It should be noted that case 5 may contain a metal material including aluminum, iron, or the like as a main component.
As shown in
As shown in
As shown in
Moreover, light-transmitting portion 6 is provided in each of the plurality of through holes 5a. The plurality of light-transmitting portions 6 correspond to the plurality of light-emitting elements 11a on a one-to-one basis. To put it another way, the plurality of light-transmitting portions 6 are disposed opposite to the plurality of light-emitting elements 11a on a one-to-one basis.
Furthermore, light-transmitting portion 6 includes a lens that performs light distribution control to cause light emitted by light-emitting element 11a and passing through light-transmitting portion 6 to have a narrow angle or a wide angle.
Moreover, a plurality of microasperities (dots, prisms) may be provided on the surface of light-transmitting portion 6 by, for example, surface texturing, or a dot pattern may be printed on the surface of the same. This makes it difficult to visually recognize light-emitting element 11a inside case 5 of lighting device 2 through light-transmitting portion 6 from the outside. Additionally, in this case, light-transmitting portion 6 is capable of mixing light emitted from light-emitting element 11a. For this reason, light-transmitting portion 6 is capable of reducing color unevenness of light exiting through the surface of light-transmitting portion 6.
The plurality of light sources 11 are disposed in internal space K of case 5 to form a spherical shape or a polyhedron shape in accordance with the outer shape of case 5. Accordingly, the plurality of light sources 11 form a shape similar to the outer shape of case 5. In the present embodiment, 19 light sources 11 are provided except for predetermined wall portion 5d1, and 19 light sources 11 form an icosahedron shape substantially.
Each of the plurality of light sources 11 includes one or more light-emitting elements 11a and substrate 11b.
Light-emitting elements 11a are substantially disposed across lighting device 2. In other words, light-emitting elements 11a are scattered to make it possible to radiate light in all directions from lighting device 2. In addition, light-emitting elements 11a are disposed at specified intervals when lighting device 2 is holistically viewed. In the present embodiment, a plurality of light-emitting elements 11a are mounted on one substrate 11b. Additionally, a plurality of light-emitting elements 11a are disposed at specified intervals on each of substrates 11b.
Moreover, each of the plurality of light-emitting elements 11a is capable of illuminating in a corresponding direction. In the present embodiment, since a plurality of light-emitting elements 11a are mounted on one substrate 11b, the plurality of light-emitting elements 11a on same substrate 11b emit light in the same direction. It should be noted that even when a plurality of light-emitting elements 11a are on same substrate 11b, each of the plurality of light-emitting elements 11a may emit light in a different direction.
Furthermore, each of the plurality of light-emitting elements 11a emits light outward of lighting device 2. Specifically, the optical axis of light-emitting element 11a is a direction perpendicular to the face included in a corresponding one of the plurality of wall portions 5c. Here, the optical axis is a straight line along principal light emitted by light-emitting element 11a.
Moreover, each light-emitting element 11a is capable of emitting light in at least two colors. Specifically, each light-emitting element 11a is a light source of three colors of RGB, and is capable of emitting monochromatic light in three colors such as red light, blue light, and green light, and at the same time emitting color light or white light obtained by dimming the monochromatic light in these three colors.
Specifically, each light-emitting element 11a is a surface-mounted device (SMD) LED element in which an LED is packaged, and includes a container (package), a plurality of LED chips mounted within the container, and a seal component that seals the plurality of LED chips. In the present embodiment, red LED chips that emit red light, blue LED chips that emit blue light, and green LED chips that emit green light are mounted as the plurality of LED chips. The seal component is a light-transmitting insulating resin material such as silicone resin. It should be noted that a light diffusing material such as silica, a filer, or the like may be dispersed in the seal component.
Substrate 11b is in a shape corresponding to face 50 in the polygonal shape in case 5. For this reason, the shape of each substrate 11b is a polygonal shape. It is possible to form a spherical shape or a polygonal shape corresponding to the outer shape of case 5 by combining the plurality of substrates 11b.
Moreover, since substrate 11b is in the shape corresponding to face 50 in the polygonal shape in case 5, substrate 11b is in at least one of a triangular shape, a quadrilateral shape, a pentagonal shape, or a hexagonal shape. In the present embodiment, substrate 11b is in a triangular shape.
Furthermore, substrate 11b is a mounting substrate including a mounting surface for mounting light-emitting element 11a. A plurality of light-emitting elements 11a are regularly disposed on substrate 11b. In the present embodiment, light-emitting element 11a is mounted on each of corner portion sides of substrate 11b in the polygonal shape.
It should be noted that, though not shown in the figure, metal wiring, a connector for power supply, etc. are provided on the mounting surface of substrate 11b. In the present embodiment, the connector for power supply of substrate 11b is electrically connected to controller 12 shown in
Moreover, substrate 11b is fastened to case 5 by being attached to each of the plurality of wall portions 5c in case 5 with a fastening component such as a screw. Accordingly, the plurality of substrates 11b are held in the spherical shape or the polygonal shape by case 5.
Examples of substrate 11b include: a metal base substrate obtained by applying an insulating film to a base material containing a metal material such as aluminum or copper; a ceramic substrate that is a sintered compact of a ceramic material such as alumina; or a resin substrate including a resin material as a base. In the present embodiment, a printed circuit substrate including a glass epoxy substrate in which metal wiring is provided is used as substrate 11b. It should be noted that substrate 11b is a rigid substrate but may be a flexible substrate.
As shown in
Moreover, controller 12 executes light-emission patterns stored in storage 15 to control a plurality of light sources 11 according to the light-emission patterns. Specifically, controller 12 controls a light-emission pattern in which each light-emitting element 11a emits light, according to control information obtained from storage 15 or an external device. In other words, controller 12 is capable of separately controlling light-emitting elements 11a of all light sources 11 included in lighting device 2 shown in
Furthermore, in the present embodiment, controller 12 is a control circuit in an elongated tabular shape or a columnar shape, and disposed in case 5 to be in an orientation perpendicular to predetermined wall portion 5d1 shown in
Power supply 13 serves to supply power to each part of lighting device 2. Power supply 13 is, for example, a power supply circuit in which a plurality of electronic components are mounted on a printed substrate. Power supply 13 generates, for example, driving power for causing each of a plurality of light sources 11 to emit light. Specifically, power supply 13 generates driving power for causing each light source 11 to emit light, and supplies the driving power to each light source 11. In other words, power supply 13 converts commercial alternating-current power to direct-current power, and supplies, as driving power for causing each light source 11 to emit light, the direct-current power to light source 11 to cause light-emitting elements 11a of light source 11 shown in
Communicator 14 serves to communicate with terminal device 20. Specifically, communicator 14 receives, from terminal device 20, control information for controlling a light-emission pattern of lighting device 2. An operating instruction and the control information received by communicator 14 are outputted to controller 12. Examples of a communication scheme used by communicator 14 include wide area network (WAN), local area network (LAN), power line communication, infrared communication, near field communication (e.g., Bluetooth (registered trademark) communication), or mobile communication for mobile phones.
Storage 15 stores, for example, light-emission patterns of a plurality of light sources 11. Moreover, light-emission patterns are stored into storage 15 by being set by terminal device 20 or being obtained from an external device. Furthermore, control information or the like obtained by controller 12 is periodically stored into storage 15. Storage 15 includes, for example, a primary storage device such as random-access memory (RAM) and read-only memory (ROM). Additionally, storage 15 may include a secondary storage device such as a hard disk drive (HDD) and a solid state drive (SSD) or a tertiary storage device such as an optical disk and an SD card.
Next, advantageous effects of lighting device 2 according to the present embodiment are described.
For example, with regard to a conventional lighting device, when each of a plurality of wall portions includes separate and independent components, it is necessary to assemble a case by connecting as many components as the number of the components. In this case, the conventional lighting device has a large number of components, and the number of assembling processes increases.
Moreover, with regard to the conventional lighting device, even when the case is assembled by connecting the plurality of wall portions that are components, a gap is provided between edge portions of two adjacent wall portions. In this case, dirt, dust, and water vapor enter the conventional lighting device through this gap.
As stated above, lighting device 2 according to the present embodiment is a lighting device capable of illuminating in all directions, lighting device 2 including: case 5 that includes a plurality of wall portions 5c each including face 50 in a polygonal shape; a plurality of light-emitting elements 11a that are provided in the plurality of wall portions 5c and emit light toward outside of lighting device 2; and controller 12 that controls the plurality of light-emitting elements 11a separately. Case 5 is of an outer shape that is spherical or polyhedral. Case 5 includes bent portions 5e that are bent in the outer shape of case 5. Bent portions 5e constitute at least three sides of the outer shape of case 5.
Accordingly, the outer shape of case 5 that is spherical or polyhedral is provided by case 5 being bent. As a result, it is possible to reduce an increase in the number of components, compared to a case in which each of the plurality of wall portions 5c of case 5 includes separate and independent components.
Moreover, since bent portion 5e is a bent line, a gap is not provided between two adjacent wall portions 5c. Consequently, case 5 makes it possible to prevent the number of gaps provided between two adjacent wall portions 5c from increasing.
Therefore, lighting device 2 is capable of achieving both a reduction of an increase in the number of assembling processes and an improvement of dust-proofing and moisture barrier properties. In consequence, it is possible to achieve both a reduction of a steep rise in manufacturing costs of lighting device 2 and protection of electronic devices disposed in case 5.
Especially, since case 5 is provided by being bent, lighting device 2 is capable of preventing the number of gaps provided in case 5 from increasing. Since this makes it possible to ensure the strength of case 5, case 5 is capable of protecting light-emitting elements 11a even when an external shock is given to lighting device 2.
Furthermore, in lighting device 2 according to the present embodiment, the polygonal shape is at least one of a triangular shape, a quadrilateral shape, a pentagonal shape, or a hexagonal shape.
Those polygonal shapes make it possible to provide a spherical shape or a polyhedral shape such that the outer shape of case 5 does not become too complex.
Moreover, in lighting device 2 according to the present embodiment, the plurality of wall portions 5c includes first wall portion 5c1 and second wall portion 5c2 adjacent to first wall portion 5c1. In addition, first edge portion 51a and second edge portion 52a constitute one side of the outer shape of case 5 and are connected to overlap each other, first edge portion 51a being one side of first wall portion 5c1, second edge portion 52a being one side of second wall portion 5c2.
Accordingly, when case 5 is viewed from the outside, it is possible to fill a gap between first edge portion 51a and second edge portion 52a. As a result, it is possible to prevent dirt, dust, and water vapor from entering between first edge portion 51a and second edge portion 52a. Therefore, lighting device 2 is capable of further improving the dust-proofing and moisture barrier properties.
The following describes a configuration of lighting device 2a according to the present embodiment.
Lighting device 2a according to the present embodiment differs from lighting device 2 according to Embodiment 1 in that protective component 90 is provided at a vertex of case 5 as shown in
Lighting device 2a includes protective component 90 in addition to case 5, the plurality of light-transmitting portions 6, the plurality of light sources 11, controller 12, power supply 13, storage 15, and communicator 14 shown in
Since the spherical or polyhedral outer shape of case 5 according to the present embodiment is provided by bending first tabular component 5b1 while providing faces 50 in the polygonal shape, gap 5a1 is provided at vertex portion 5g of case 5. Accordingly, when protective component 90 is provided in gap 5a1 at vertex portion 5g of case 5, protective component 90 makes it possible to cover vertex portion 5g of case 5 and fill gap 5a1 provided at vertex portion 5g of case 5. In the present embodiment, protective components 90 are provided at all vertex portions 5g in case 5.
As shown in
Specifically, protective component 90 includes insertion portion 91 and head portion 92.
Insertion portion 91 is in a columnar shape that is insertable into gap 5a1 provided at vertex portion 5g of case 5, and projects from head portion 92.
Moreover, insertion portion 91 is equal in size and shape to the opening surface of gap 5a1 at vertex portion 5g of case 5. For this reason, protective component 90 is fixed to vertex portion 5g of case 5 by insertion portion 91 being inserted into gap 5a1 at vertex portion 5g of case 5.
Head portion 92 is in, for example, a columnar shape, a spherical shape, or a polygonal shape. Head portion 92 is a portion exposed from case 5 when protective component 90 is provided at vertex portion 5g of case 5. In other words, head portion 92 is provided in a state in which head portion 92 projects from a plurality of faces 50 in the polygonal shape in case 5.
Furthermore, when protective component 90 is viewed along face 50 in the polygonal shape included in each of wall portions 5c constituting vertex portion 5g, head portion 92 projects further outward of case 5 than face 50 in the polygonal shape. In addition, when protective component 90 is viewed along face 50 I the polygonal shape, protective component 90 projects further outward of case 5 than light-transmitting portion 6. In this case, when lighting device 2a is placed on a flat mounting surface, it is possible to separate face 50 in the polygonal shape and light-transmitting portion 6 from the flat mounting surface by head portions 92 abutting on the flat mounting surface. Accordingly, protective component 90 makes it possible to prevent face 50 in the polygonal shape and light-transmitting portion 6 in case 5 from being damaged as a result of contacting the flat mounting surface.
Moreover, in the present embodiment, protective component 90 contains a resin material such as polycarbonate or ABS. It should be noted that protective component 90 may contain a metal material including aluminum, iron, or the like as a main component.
Next, advantageous effects of lighting device 2a according to the present embodiment are described.
As stated above, lighting device 2a according to the present embodiment includes protective component 90 that is provided to cover vertex portion 5g of case 5.
Accordingly, when the outer shape of case 5 that is spherical or polyhedral is provided by bending a tabular component while providing faces 50 in the polygonal shape, gap 5a1 is provided at vertex portion 5g of case 5. In the present embodiment, however, protective component 90 is capable of filling gap 5a1 at vertex portion 5g of case 5. Therefore, lighting device 2a is capable of further improving the dust-proofing and moisture barrier properties.
Moreover, in lighting device 2 according to the present embodiment, when protective component 90 is viewed along face 50 in the polygonal shape, protective component 90 projects further outward of case 5 than faces 50 in the polygonal shape that constitute vertex portion 5g.
Accordingly, when lighting device 2a is placed on a mounting surface, protective components 90 are capable of separating respective faces 50 in the polygonal shape from the mounting surface. As a result, protective components 90 are capable of protecting respective faces 50 in the polygonal shape from being damaged. Additionally, protective components 50 are also capable of protecting vertex portions 5g of case 5 from being damaged.
In addition, when lighting device 2a is placed on a mounting surface, a space is provided by protective components 90 between respective faces 50 in the polygonal shape and the mounting surface. For this reason, it is possible to transmit light emitted by light sources 11 facing the mounting surface to the outside of lighting device 2a.
Furthermore, in lighting device 2a according to the present embodiment, light-transmitting portion 6 that transmits light emitted by light-emitting element 11a is provided in at least one wall portion 5c among the plurality of wall portions 5c. When protective component 90 is viewed along face 50 in the polygonal shape, protective component 90 projects further outward of case 5 than light-transmitting portion 6.
Accordingly, when lighting device 2a is placed on a mounting surface, protective component 90 is capable of separating light-transmitting portion 6 from the mounting surface. For this reason, protective component 90 is capable of preventing light-transmitting portion 6 from being damaged.
The present embodiment produces the same advantageous effects as those described above.
