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.

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.

In addition, the shape of the luminaire 1 is not limited to the shape of a substantially quadrangular prism, and may be a shape like a cylinder. The shape like a cylinder includes an ellipse and the like in addition to a circle having a constant radius. In an example of the configuration of the lighting fixture 1 according to the present embodiment, the shape of a square pillar will be described.

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 a lid portion 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. Further, the upper surface of the control housing 14 is referred to as a top plate 21. That is, the upper surface plate 21 corresponds to the upper surface of the quadrangular prism.

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 controls the image display of the electronic panel 12 and the light emission 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). ..

<Mechanism for adjusting the orientation of lighting equipment>
Next, a mechanism for adjusting the orientation of the luminaire 1 will be described with reference to FIGS. 2 to 4. FIG. 2 is a sectional view taken along the line AA of the lighting fixture 1 shown in FIG. FIG. 3 is a sectional view taken along line BB of the lighting fixture 1 shown in FIG. FIG. 4 is a perspective view showing an example of a configuration that limits the rotation angle of the luminaire 1. FIG. 4 is a view of the vicinity of the support plate 23 viewed obliquely from the negative direction of the Z axis with the surface parallel to the X axis as the front surface. In FIGS. 2 to 3, drawing of the control unit 15 and the like is omitted.

The upper surface plate 21 of the control housing 14 has a circular hole 22 having a predetermined radius in the center. The circular hole 22 may be covered by a circular lid 18.

Below the top plate 21, a support plate 23 that is larger than the radius of the circular hole 22 and is a plate that supports the top plate 21 from below is arranged. As shown in FIG. 3, the support plate 23 is a circular plate larger than the radius of the circular hole 22, and is a disk portion 23A that supports the upper surface plate 21 from below, and a flat cylinder smaller than the radius of the circular hole 22. It may be composed of a convex portion 23B having a shape and fitting into the circular hole 22. Alternatively, the support plate 23 may have a disk portion 23A and no convex portion 23B. According to this configuration, as shown in FIG. 3, the top plate 21 is supported by the disk portion 23A of the support plate 23. The top plate 21 and the support plate 23 may be made of a material having a certain degree of friction, and may be made of, for example, galvanized steel.

The lid portion 18 and the support plate 23 have through holes 24A and 24B for passing the power cable 16 in the center, respectively. In addition, the lid 18 and the support plate 23 have through holes 25A and 25B for passing the wire 17 at positions at predetermined distances from the center, respectively. For example, as shown in FIG. 1, the lid portion 18 and the support plate 23 penetrate two penetrations at positions equidistant from the center (for example, the radius of the support plate 23) on a straight line M1 passing through the center and parallel to the horizontal plane. It has holes 25A and 25B, respectively.

The power cable 16 extends upward from the control unit 15 inside the control housing 14 through the through holes 24A and 24B of the support plate 23 and the lid portion 18, and suspends the lighting fixture 1 such as a ceiling, a beam, or a writing rail. It is connected to a power supply (not shown) provided on the member (hereinafter referred to as "hanging 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 engaged with the through hole 25B of the support plate 23, and the other end is fixed to the hanging member. The number of wires 17 may be one, two as shown in FIGS. 1 to 4, or three or more.

According to the above configuration, the horizontal rotation of the support plate 23 about the straight line C extending in the vertical direction through the center of the support plate 23 is hindered by the wire 17. On the other hand, the upper surface plate 21 is supported by the disk portion 23A of the support plate 23 without being connected to the support plate 23. Therefore, the control housing 14 including the top plate 21 and the electronic panel 12 connected to the control housing 14 can rotate horizontally with the straight line C as the rotation axis. Therefore, when the luminaire 1 is suspended and installed, the operator can adjust the electronic panel 12 in an arbitrary direction by horizontally rotating the top plate 21 with the straight line C as the rotation axis. Since the top plate 21 and the support plate 23 have a certain amount of friction, the top plate 21 does not rotate horizontally after adjusting the orientation of the electronic panel 12. Thereby, for example, when different images are displayed on the four electronic panels 12, the operator can install the luminaire 1 so that each image faces the desired direction.

Further, since the convex portion 23B of the support plate 23 fits into the circular hole 22 of the upper surface plate 21, the upper surface plate 21 does not shift in the horizontal direction with respect to the support plate 23.

Further, by providing the wire 17, the weight of the control housing 14 and the electronic panel 12 hanging on the support plate 23 is distributed not only to the power cable 16 but also to the wire 17. Therefore, the lighting fixture 1 can be hung more safely.

If the lighting fixture 1 can be hung sufficiently safely by the power cable 16, the wire 17 may not be provided. In this case, a part of the power cable 16 may be fixed to the support plate 23. As a result, the horizontal rotation of the support plate 23 about the straight line C as the rotation axis is hindered by the torsional rigidity of the power cable 16 and / or the restoring force against the torsion. Therefore, the operator can adjust the electronic panel 12 in an arbitrary direction by horizontally rotating the control housing 14 and the electronic panel 12 with the straight line C as the rotation axis, as in the case described above.

<Mechanism that limits the rotation angle of the control housing and electronic panel>
Next, with reference to FIGS. 1 to 4, a function of limiting the rotation angle of the control housing 14 and the electronic panel 12 will be described.

As shown in FIGS. 1 to 4, the support plate 23 is provided with a protrusion 26 projecting downward at a predetermined distance R1 from the center. As shown in FIG. 1, the protrusion 26 may be provided on a straight line M2 that is orthogonal to the straight line M1 and passes through the center of the support plate 23. The protrusion 26 may be, for example, a screw extending downward.

As shown in FIGS. 2 and 4, the luminaire 1 includes a rotation stopper 27 below the support plate 23. Although not shown in FIGS. 2 and 3, the rotation stopper 27 is connected to the control housing 14 or the control unit 15. That is, when the control housing 14 is rotated horizontally, the rotation stopper 27 moves together with the control housing 14.

The rotation stopper 27 has a collision plate 28 at a position where the protrusion 26 collides when the upper surface plate 21 is horizontally rotated by a predetermined angle with the straight line C as the rotation axis. For example, as shown in FIGS. 2 to 4, the rotation stopper 27 has a collision plate 28 at a position at a predetermined distance R1 in the horizontal direction from the straight line C. As shown in FIGS. 2 to 4, the collision plate 28 may be a plate perpendicular to the horizontal rotation direction of the upper surface plate 21 having the straight line C as the rotation axis.

The number of collision plates 28 may be one. In this case, the horizontally rotatable angle of the top plate 21 is limited to about 360 degrees. Alternatively, the number of collision plates 28 may be two, as shown in FIGS. 2 to 4. In this case, the horizontally rotatable angle of the top plate 21 is limited to the angle formed by the two straight lines extending from the straight line C to the positions of the two collision plates 28, respectively. For example, as shown in FIGS. 1 to 3, when two collision plates 28 are arranged at positions of a predetermined distance R1 with a straight line C in between, the horizontal rotatable angle of the top plate 21 is about 180 degrees. Limited to. According to this configuration, it is possible to prevent the operator from rotating the top plate 21 too much and twisting the power cable 16 too much when adjusting the orientation of the electronic panel 12.

(Summary of this disclosure)
The lighting fixture (1) according to the present disclosure has a columnar shape extending in the vertical direction, forms a light source (11) that emits light, and a columnar side surface that surrounds the light source, and processes and transmits the light emitted by the light source. An electronic panel (12), a top plate (21) forming a columnar upper surface and having a circular hole (22) in the center, and a plate larger than the circular hole and supporting the top plate from below. A support plate (23) having one through hole (24B) and a second through hole (25B) at a predetermined distance from the center, and a lighting fixture extending upward through the first through hole. A power cable (16) connected to a power source provided in the hanging member of the lamp, and a wire (one end engaged with a second through hole and the other end fixed to the hanging member of the lighting fixture 17) and. The columnar column may be a regular square column.

According to this configuration, the wire allows the luminaire to be hung more safely. In addition, since the support plate is prevented from rotating by the wire, the top plate can be rotated horizontally. Therefore, the operator can adjust the electronic panel in any direction by horizontally rotating the top plate when the luminaire is suspended and installed.

Further, the support plate is a circular plate larger than the radius of the circular hole and has a disk portion (23A) that supports the upper surface plate from below, and a flat cylindrical shape smaller than the radius of the circular hole to form a circular hole. It may include a protruding portion (23B) to be fitted.

According to this configuration, since the convex portion fits into the circular hole of the upper surface plate, the upper surface plate does not shift in the horizontal direction with respect to the support plate.

Further, the lighting fixture is provided on the support plate, and a protrusion (26) protruding downward from the support plate and a straight line (C) in which the upper surface plate extends vertically through the center of the upper surface plate are defined as rotation axes. A collision plate (28) arranged at a position where the protrusions collide with each other when the protrusions are rotated horizontally may be further provided.

According to this configuration, the horizontally rotatable angle of the top plate is limited by the protrusions and the collision plate, so that the operator can prevent the top plate from being rotated too horizontally and twisting the power cable too much. ..

Although the embodiments have been described above with reference to the accompanying drawings, the present disclosure is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications, modifications, substitutions, additions, deletions, and equality examples within the scope of the claims. It is understood that it belongs to the technical scope of the present disclosure. Further, each component in the above-described embodiment may be arbitrarily combined as long as the gist of the invention is not deviated.

The techniques of the present disclosure can be applied to luminaires.
