Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanations of already well-known matters and duplicate explanations for substantially the same configuration may be omitted. This is to avoid unnecessary redundancy of the following description and to facilitate the understanding of those skilled in the art. It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter of the claims.

(Implementation)
FIG. 1 is a perspective view showing an example of a configuration of a lighting fixture according to the present embodiment.

For convenience of explanation, as shown in FIG. 1, the axis extending in the vertical direction (height direction) is the Z axis, one axis orthogonal to the Z axis is the X axis, and the X axis and the axis orthogonal to the Z axis are Is the Y axis. Further, the positive direction of the Z axis may be referred to as "up", the negative direction of the Z axis may be referred to as "down", the positive direction of the X axis may be referred to as "right", and the negative direction of the X axis may be referred to as "left". Further, the XY plane may be referred to as a horizontal plane, and the plane perpendicular to the XY plane may be referred to as a vertical plane. However, the expressions related to these directions are used for convenience of explanation, and are not intended to limit the posture of the structure in actual use.

The luminaire 1 has a columnar shape extending in the vertical direction. For example, as shown in FIG. 1, the luminaire 1 exhibits the shape of a substantially quadrangular prism extending in the vertical direction. However, the shape of the luminaire 1 is not limited to a square prism, and may be another prism such as a triangular prism, a pentagonal prism, a hexagonal prism, or an octagonal prism. Further, the shape of the luminaire 1 is not limited to a regular prism (for example, a regular square pillar), and may be any prism.

The luminaire 1 includes a light source 11, an electronic panel 12, a lower surface panel 13, a control housing 14, a control unit 15, a power cable 16, a wire 17, and an outer pillar 18.

The light source 11 is a device that is arranged inside a square pillar and emits light. As shown in FIG. 1, the light source 11 is a spherical LED bulb. Alternatively, the light source 11 may be a rod-shaped LED fluorescent lamp extending downward.

The electronic panels 12 are arranged in a square tube shape so as to form the four side surfaces of the quadrangular prism. That is, the luminaire 1 includes four electronic panels 12. Hereinafter, the line of intersection of the side surfaces of the square pillars formed by the electronic panels 12 adjacent to each other will be referred to as a side ridge 30. Further, the electronic panel 12 can display an image, and processes and transmits the light emitted by the light source 11. The image displayed on the electronic panel 12 may be either a still image or a moving image. Examples of the electronic panel 12 include a liquid crystal panel or an OLED (Organic Light-Emitting Diode) panel.

A person who sees the luminaire 1 can visually recognize the image displayed on the electronic panel 12 by using the light emitted by the light source 11 as a backlight. In addition, since the distance from the light source 11 to each pixel of the electronic panel 12 is different in the lighting fixture 1, the amount of light received by each pixel of the electronic panel 12 is different. In addition, a diffusion sheet that diffuses light may be attached to the inside of the electronic panel 12. According to these configurations, the image displayed on the electronic panel 12 of the luminaire 1 is different from the image displayed on a general liquid crystal monitor provided with a flat backlight to the person who sees the luminaire 1. It is visually recognized by. Therefore, by using the lighting fixture 1, various effects that are difficult to realize with a general liquid crystal monitor can be realized.

The lower surface panel 13 is arranged so as to form the lower surface of the quadrangular prism. That is, the four sides of the lower surface panel 13 are fixed to the lower sides of the four electronic panels 12. The bottom panel 13 may be a transparent panel or a translucent panel having a predetermined color. Alternatively, the luminaire 1 does not have to include the bottom panel 13.

The control housing 14 is arranged so as to form an upper portion of a quadrangular prism. The shape of the control housing 14 may be a quadrangular prism or, as shown in FIG. 1, a quadrangular pyramid.

The control unit 15 is a device that is arranged inside the control housing 14 and controls the image display of the electronic panel 12. In addition, the control unit 15 may control the light emission of the light source 11. Examples of light emission control of the light source 11 include control of the blinking pattern of the light source 11 and control of the amount of light. The control unit 15 may be a circuit board including a processor, a memory, and a communication I / F (Interface). The processor may perform image display control of the electronic panel 12 and light emission control of the light source 11 based on a predetermined program and data read from the memory. Further, the processor may receive image data to be displayed on the electronic panel 12 and data related to light emission control of the light source 11 from a predetermined server through the communication I / F and store the data in the memory. The communication I / F may be an I / F that performs wired communication represented by Ethernet (registered trademark) or an I / F that performs wireless communication represented by WiFi (registered trademark). ..

The power cable 16 extends upward from the control unit 15 inside the control housing 14 through the upper surface of the control housing 14 to suspend the lighting fixture 1 such as a ceiling, a beam, or a writing rail (hereinafter, “hanging”). It is connected to a power supply (not shown) provided in the "member"). The light source 11, the electronic panel 12, and the control unit 15 are operated by the electric power supplied through the power cable 16.

One end of the wire 17 is attached to the upper surface of the control housing 14, and the other end is fixed to the hanging member. The number of wires 17 may be one, two may be two as shown in FIG. 1, or three or more may be used.

According to the above configuration, the force for suspending the luminaire 1 is distributed to the power cable 16 and the wire 17. Therefore, the lighting fixture 1 can be hung more safely. However, if it is sufficiently safe to suspend by the power cable 16, the wire 17 may not be provided. The method of installing the lighting fixture 1 is not limited to the case where it is hung, and it may be placed on the ground, floor, table, or the like.

The outer pillar 18 is attached along the outer side ridge 30 of the square pillar and fixes the electronic panels 12 adjacent to each other. The outer pillar 18 may have a configuration having a region having a predetermined width W in the horizontal direction (X direction or Y direction) from one side in the vertical direction of the electronic panel 12. The outer pillar 18 may be made of an opaque resin, plastic, or the like. The width W of the outer pillar 18 may be determined based on the image display area on the electronic panel 12, the design of the luminaire 1, the strength required for the luminaire 1, and the like.

FIG. 2 is an enlarged perspective view showing an example of the configuration near the outer pillar 18. FIG. 2 is a view seen obliquely from the positive direction of the Z axis with the electronic panel 12 parallel to the X axis as the front surface. FIG. 3 is an enlarged top view showing an example of the configuration near the outer pillar 18. FIG. 3 is a view of the Z-axis from the positive direction to the negative direction of the Z-axis. Note that in FIGS. 2 and 3, drawing of the lower panel 13, the control housing 14, the control unit 15, the power cable 16, the wire 17, and the like is omitted.

The electronic panel 12 is provided with a flexible substrate 19 extending inward of a square pillar from a substrate connecting side 31 which is one side of the electronic panel 12 in the vertical direction. The flexible substrate 19 is electrically connected to the control unit 15 and causes the electronic panel 12 to display an image based on the signal received from the control unit 15.

The luminaire 1 includes an inner pillar 20 that is attached to the inside of the side ridge 30 of the square pillar along the side ridge 30 and covers the flexible substrate 19. As shown in FIGS. 2 and 3, the horizontal cross section of the inner pillar 20 has a U-shape (U-shape) protruding in the direction approaching the light source 11. However, the horizontal cross section of the inner pillar 20 is not limited to the U shape, and may be, for example, a V shape or an arc shape. By providing the inner pillar 20, the flexible substrate 19 is protected and the position of the flexible substrate 19 is fixed. A resin member may be sandwiched between the inner pillar 20 and the flexible substrate 19, and the inner pillar 20 may be made of a metal member. By forming the inner pillar 20 with a metal member, it is possible to suppress external leakage of electromagnetic noise radiated from the flexible substrate 19.

That is, the inner pillar 20 is attached from the inside of the electronic panel 12 along the substrate connecting side 31 so as to cover the flexible substrate 19. The outer pillar 18 is attached from the outside of the electronic panel 12 along the substrate connecting side 31 so as to cover a part of the electronic panel 12 with a predetermined width W orthogonal to the substrate connecting side 31.

Further, both ends of the inner pillar 20 are connected to parts to which both ends of the outer pillar 18 are connected. Although not shown in FIG. 2, the inner pillar 20 is connected from one end to the other and supports the whole like the outer pillar 18. By making the inner pillar 20 a hard and hard-to-break material such as metal, the strength of the lighting fixture 1 can be increased.

Further, the portion surrounded by the inner pillar 20 is a portion of the flexible board 19 where heat is particularly likely to be generated. Therefore, heat tends to be trapped inside the inner pillar 20. Therefore, as shown in FIG. 2, the inner pillar 20 may have a shape in which the front portion in the middle of the pillar is hollowed out so that the flexible base 19 can be seen. As a result, the heat generated from the flexible board 19 can be released from the hollowed out portion of the inner pillar 20.

As shown in FIG. 3, the inner pillar 20 can block the light 32 emitted by the light source 11 and form a shadow on the electronic panel 12. Therefore, in the present embodiment, the outer pillar 18 and the inner pillar 20 are shaded by the shadow formed on the electronic panel 12 by the inner pillar 20 blocking the light 32 of the light source 11 (the region having a width W). Configure to fit in.

For example, as shown in FIG. 3, the angle θ between the protruding direction of the inner pillar 20 and the electronic panel 12 is set, and the shadow formed on the electronic panel 12 by the protrusion of the inner pillar 20 is the region (width W) of the outer pillar 18. It is configured to fit in the area of). The range that the angle θ can take is determined based on the length L of the inner pillar 20 in the protruding direction, the width W of the outer pillar 18, and the position, shape, and size of the light source 11.

As a result, the shadow formed on the electronic panel 12 by the inner pillar 20 blocking the light 32 of the light source 11 fits in the region of the outer pillar 18 (the region of the width W), so that the shadow looks at the luminaire 1. Not visible to people. That is, in the luminaire 1, it is possible to prevent the flexible substrate 19 extending from the edge of the electronic panel 12 displaying an image from forming a shadow on the electronic panel 12.

The angle θ may be one half of the angle of the horizontal plane formed by the two adjacent electronic panels 12. For example, when the shape of the luminaire 1 is a regular quadrangular prism, the angle of the horizontal plane formed by the two adjacent electronic panels 12 is 90 degrees, so that the angle θ is approximately 45 degrees (for example, 45 degrees ± 5 degrees). It may be there. For example, when the shape of the luminaire 1 is a regular hexagonal prism, the angle of the horizontal plane formed by the two adjacent electronic panels 12 is 120 degrees, so that the angle θ is approximately 60 degrees (for example, 60 degrees ± 5 degrees). It may be there. As a result, the size of the shadow of the inner pillar 20 is minimized, so that the width W of the outer pillar 18 can be minimized (that is, the thinnest).

<Modification example>
In the above description, the case where the luminaire 1 has the shape of a prism has been described, but the shape of the luminaire 1 is not limited to the prism. Next, a case where the shape of the luminaire 1 is a cylinder will be described.

FIG. 4 is a top view showing an example of the configuration of the cylindrical lighting fixture 1. FIG. 4 is a view of the Z-axis from the positive direction to the negative direction of the Z-axis. Note that FIG. 4 omits drawing of the lower surface panel 13, the control housing 14, the control unit 15, the power cable 16, the wire 17, and the like.

As shown in FIG. 4, the luminaire 1 may have a configuration in which one curved electronic panel 12 is arranged so as to form a side surface of a cylinder (that is, in a cylindrical shape). Alternatively, the luminaire 1 may have a configuration in which a plurality of curved electronic panels 12 are arranged so as to form a side surface of a cylinder (that is, in a cylindrical shape).

The electronic panel 12 is provided with a flexible substrate 19 extending inward of a cylinder from a substrate connecting side 31 which is one side of the electronic panel 12 in the vertical direction.

The outer pillar 18 is attached from the outer side surface of the cylinder along the substrate connecting side 31 of the electronic panel 12. As a result, the outer pillar 18 covers the gap between the substrate connecting side 31 and one side of the adjacent electronic panel 12, and fixes the arrangement of the electronic panel 12.

The inner pillar 20 is attached along the substrate connecting side 31 so as to cover the flexible substrate 19 extending from the substrate connecting side 31 of the electronic panel 12 from the inner side surface of the cylinder.

As described above, even if the luminaire 1 has a cylindrical shape, the length L of the inner pillar 20 in the protruding direction, the width W of the outer pillar 18, the position, shape and size of the light source 11 are the same as in the case of FIG. Based on the above, the possible range of the angle θ can be determined. That is, even if the luminaire 1 has a cylindrical shape, by providing the outer pillar 18 and the inner pillar 20 as in the case of FIG. 3, the inner pillar 20 interferes with the light 32 of the light source 11 to form the electronic panel 12. It is possible to prevent the formed shadow from being visually recognized by the viewer of the luminaire 1.

When the luminaire 1 has a right-angled shape, the angle θ may be approximately 90 degrees (for example, 90 degrees ± 5 degrees). As a result, the size of the shadow of the inner pillar 20 is minimized, so that the width W of the outer pillar 18 can be minimized (that is, the thinnest).
