Description

[Technical Field]

[0001] The present invention relates to a lighting device, and more particularly to a lighting device that is used in a state where it is attached to a predetermined attachment location such as a wall or ceiling. [Background technology]

[0002] Conventionally, lighting devices that are fixed to a wall and irradiate illumination light toward a predetermined area in a room have been distributed on the market, as disclosed in, for example, the following Non-Patent Document 1. A schematic diagram of this product is shown in FIG. [Prior art documents] [Non-patent literature]

[0003] [Non-Patent Document 1] Endo Lighting LED Lighting General Catalog LEDZ Pro.5 p.998(2023) Summary of the Invention [Problem to be solved by the invention]

[0004] 1 is a so-called spotlight type lighting device, and includes a lighting fixture 91 and a mounting member 93. The lighting fixture 91 is cylindrical in shape and has a built-in light source (not shown), and emits light L91 from a light extraction surface 92 to the outside of the lighting fixture 91. The mounting member 93 is a member for fixing and mounting the lighting fixture 91 to a mounting location 95 such as a wall or ceiling.

[0005] When attaching the lighting fixture 91 to the attachment location 95, the attachment member 93 is brought into contact with the attachment location 95 and then fastened with a screw 94 such as a screw. As a result, light L91 is emitted from the lighting fixture 91 into the space while the lighting fixture 91 is fixed to the attachment location 95.

[0006] However, as shown in Fig. 1, when the lighting device 90 is attached to the attachment location 95, i.e., when the lighting device 90 is in use, the heads of the screws 94 are inevitably exposed. In particular, when the lighting device 90 is used in a museum, event room, or the like, where high design quality is required, it is not desirable for the heads of the screws 94 to be visible.

[0007] It is possible to make the heads of the screws 94 substantially less noticeable by coloring the screws 94 themselves in the same color as the mounting member 93. However, even with this method, because the heads of the screws 94 are threaded, it may be difficult to make the heads of the screws 94 completely less noticeable due to light reflection, etc. If the heads of the screws 94 can be made to completely blend in with the mounting member 93 by coloring the screws 94, then conversely, when removing the lamp fixture 91 from the mounting location 95, it becomes difficult to see the position of the heads of the screws 94, reducing workability.

[0008] In view of the above problems, the present invention aims to provide a lighting device that does not significantly impair the workability of installation and removal, while making the heads of the mounting screws used during installation less noticeable even when the lighting device is attached to a predetermined installation location such as a wall or ceiling. [Means for solving the problem]

[0009] The lighting device according to the present invention comprises: a cylindrical lamp housing a light source; a mounting member connected to the lamp; a cover member disposed in contact with a first surface of the mounting member that is closer to the lamp fixture and that is rotatable about an axis that is parallel to a normal to the first surface; a screw hole formed through a portion of the mounting member, into which a mounting screw can be fitted for connecting to a planned mounting location; The cover member is characterized in that it is configured to be able to transition between a first state in which the screw hole is blocked and a second state in which the screw hole is exposed by rotating and moving while in contact with the first surface.

[0010] According to the above configuration, when attaching the lighting device to the intended attachment location, the cover member is placed in the second state to expose the screw holes, and the mounting screws are fitted into the screw holes and then screwed into the intended attachment location. The cover member is then rotated to transition from the second state to the first state, causing the heads of the mounting screws fitted into the screw holes to be blocked by the cover member. This makes the heads of the mounting screws invisible even when the lighting device is attached to the intended attachment location.

[0011] Furthermore, when removing the lighting device attached to the mounting location, the cover member, which indicates the first state, can be rotated to transition to the second state, thereby exposing the heads of the mounting screws. This makes it easy to visually confirm the positions of the screw heads. Then, by contacting the screw heads with a tool and loosening the mounting screws, the mounting member can be removed from the mounting location.

[0012] The cover member may completely cover the first surface of the mounting member in the first state. In this case, the surface of the cover member may have substantially the same shape as the first surface of the mounting member. Typically, the shape of the surface of the cover member is similar to or has the same size as the shape of the first surface of the mounting member. Specifically, if the first surface of the mounting member is rectangular, the surface of the cover member may also be rectangular, and if the first surface of the mounting member is hexagonal, the surface of the cover member may also be hexagonal.

[0013] The planned installation location of the lighting device or the installation location of the lighting device is, for example, a wall or ceiling of a building, a room, or an installation object such as a cabinet installed in a room. In this specification, the two terms "planned installation location" and "installation location" are used appropriately depending on whether the lighting device is in a state before or after being installed in a predetermined location, but both refer to the same location.

[0014] The lighting device includes a plurality of recesses provided on the first surface of the mounting member or on a surface of the cover member closer to the mounting member, the recesses being arranged to sandwich the axis; a magnet fitted in the recess, The cover member may be made of a ferromagnetic material and may be rotatable about the axis while being in contact with the first surface of the mounting member via the magnet.

[0015] In another aspect, the lighting device comprises: a recess provided on the first surface of the mounting member or on a surface of the cover member closer to the mounting member so as to surround the shaft; a magnet fitted in the recess, The cover member may be made of a ferromagnetic material and may be rotatable about the axis while being in contact with the first surface of the mounting member via the magnet.

[0016] With the above-described configuration, the cover member can be rotated while maintaining a state in which it is in contact with the mounting member due to the magnetic force of the magnet.

[0017] The lighting device includes a support member extending from an outer surface of the lamp fixture that is different from the outer surface on which the light extraction surface is located toward the mounting member; a first hole portion formed by penetrating a portion of the cover member; a second hole portion formed through a portion of the mounting member, The support member may pass through the first hole portion and the second hole portion, and be fixed to the mounting member at a second surface of the mounting member that is the surface opposite to the first surface, and may also be fixed to the cover member at a surface of the cover member that is closer to the lighting fixture.

[0018] According to the above configuration, the cover member can be rotated while the cover member and the mounting member are connected to the lamp. [Effects of the Invention]

[0019] According to the lighting device of the present invention, the heads of the mounting screws are not visible even when the lighting device is attached to a predetermined mounting location such as a wall or ceiling, ensuring a high level of aesthetic appeal. In addition, the lighting device can be attached and detached with simple operations. [Brief explanation of the drawings]

[0021]

[0023] The following description will be made with reference to the accompanying drawings, each of which is a schematic representation of an illumination device according to an embodiment of the present invention. The dimensions and number of elements in the drawings do not necessarily correspond to the actual dimensions and number of elements.

[0022] 2 and 3 are schematic perspective views of the lighting device 1 of this embodiment. Note that Fig. 3 is a view showing the lighting device 1 viewed from a different direction than Fig. 2. Fig. 4 is a schematic exploded perspective view of the lighting device 1.

[0023] 2 to 4, the lighting device 1 includes a cylindrical lighting fixture 2, a cover member 10, and an attachment member 20. The cover member 10 is in contact with one surface (first surface 20A) of the attachment member 20. The lighting fixture 2 has a built-in light source (not shown), and emits light L2 to the outside of the lighting device 1 via a light extraction surface 3.

[0024] As shown in Fig. 4, mounting member 20 is configured so that mounting screws 30 can be attached. Mounting member 20 is also configured so that magnet 41 can be fitted to first surface 20A side. Fig. 5 is a schematic perspective view of mounting member 20 shown in Fig. 4 with mounting screws 30 and magnet 41 removed. Fig. 6 is a schematic plan view of mounting member 20 in the state of Fig. 5, viewed from first surface 20A side.

[0025] 5 and 6, mounting member 20 has a plurality of recesses 22 on the first surface 20A side, and magnets 41 can be fitted into these recesses 22. For example, mounting member 20 can be made of two members, with through holes formed in the first member at positions corresponding to the recesses 22, and recesses 22 can be formed by welding a flat second member to the first member and closing the bottom of the through holes with the second member. As an alternative method, mounting member 20 can be made of a single member, and recesses 22 can be formed by carving positions corresponding to recesses 22 from the first surface 20A side.

[0026] 5, the mounting member 20 has a screw hole 23 formed therethrough from the first surface 20A to the surface opposite the first surface 20A. FIG. 4 schematically illustrates a state in which a mounting screw 30 is inserted into the screw hole 23 shown in FIG.

[0027] As shown in Fig. 4, a first hole 11 is formed in a portion of the cover member 10 included in the lighting device 1 of this embodiment so as to penetrate the cover member 10. Also, as shown in Fig. 4, a second hole 21 is formed in a portion of the mounting member 20 included in the lighting device 1 of this embodiment so as to penetrate the mounting member 20. These first hole 11 and second hole 21 are provided to allow a support member 4 extending from the wall surface of the lamp 2 to pass through. With the support member 4 passing through the first hole 11 and the second hole 21, the support member 4 is fastened and fixed by a fastening portion 51 on the surface (second surface 20B) of the mounting member 20 opposite to the first surface 20A.

[0028] As shown in FIG. 2, when the lighting device 1 is attached to the attachment location 5, the cover member 10 is visible, but the head of the attachment screw 30 located on the first surface 20A side of the attachment member 20 is not visible.

[0029] The cover member 10 is made of a ferromagnetic material, and is maintained in contact with the first surface 20A of the mounting member 20 by the magnetic force of the magnet 41. However, the cover member 10 can rotate about an axis that is the normal to the first surface 20A while maintaining the state of contact with the first surface 20A of the mounting member 20. In this embodiment, the support member 4 that passes through the first hole portion 11 and the second hole portion 21 may constitute the axis.

[0030] 7 and 8 are schematic plan views illustrating states in which the cover member 10 rotates. The cover member 10 is configured to transition between a first state S1 in which the cover member 10 overlaps the first surface 20A of the mounting member 20, thereby blocking the screw holes 23 formed in the mounting member 20, and a second state S2 in which the cover member 10 overlaps the first surface 20A of the mounting member 20, while exposing the screw holes 23 formed in the mounting member 20. Specifically, the cover member 10 transitions from the first state S1 shown in FIG. 7 to the second state S2 shown in FIG. 8 by rotating the cover member 10 along a direction C10. For convenience of explanation, FIGS. 7 and 8 illustrate a state in which the support member 4 does not penetrate the first hole portion 11 and the second hole portion 21. Note that FIG. 7 illustrates a case in which the direction C10 is counterclockwise when viewing the mounting member 20 from the cover member 10, but the rotation direction of the cover member 10 shown in FIG. 7 is merely an example. Needless to say, the cover member 10 may also be rotated clockwise.

[0031] When attaching the lighting device 1 to the attachment location 5 (planned attachment location 5), as shown in Fig. 9, the cover member 10 is rotated to the second state S2 to expose the screw hole 23. Thereafter, the attachment screw 30 is fitted into the screw hole 23 and screwed into a predetermined location in the planned attachment location 5. In this state, the screw head of the attachment screw 30 is visible.

[0032] Thereafter, the cover member 10 is rotated to the first state S1, whereby the head of the attachment screw 30 is hidden by the cover member 10 as shown in FIG.

[0033] Conversely, when removing the lighting device 1 from the mounting location 5, the cover member 10 is rotated to the second state S2, where the heads of the mounting screws 30 are visible. Thereafter, a tool (not shown) is brought into contact with the heads of the mounting screws 30 to loosen the mounting screws 30, and the mounting member 20 is removed from the mounting location 5.

[0034] [Another embodiment] Another embodiment of the lighting device 1 will be described below.

[0035] <1> The number of magnets 41 included in the lighting device 1 is not limited to four. For example, as shown in Fig. 10 , recesses 22 may be formed in two locations on the first surface 20A of the mounting member 20, and a magnet 41 may be fitted into each recess 22.

[0036] When multiple magnets 41, 41 are installed on the mounting member 20, it is preferable that the multiple magnets 41, 41 are positioned so as to sandwich the rotation axis of the cover member 10. When the support member 4 extending from the lamp 2 passes through the cover member 10 and the mounting member 20 as in the above-described embodiment, it is preferable that the multiple magnets 41, 41 are positioned so as to sandwich the support member 4.

[0037] 11, an annular recess 22 may be formed in the first surface 20A of the mounting member 20, and the annular magnet 41 may be fitted into the recess 22. In this case, a single magnet 41 is installed on the mounting member 20.

[0038] <2> In the above embodiment, the cover member 10 is rotated while maintaining the cover member 10 in contact with the first surface 20A of the mounting member 20 by the magnetic force of the magnet 41. However, if the support member 4 extending from the lamp 2 penetrates the cover member 10 and the mounting member 20, the cover member 10 will not fall off even if the cover member 10 is rotated while being separated from the first surface 20A of the mounting member 20. Therefore, it is not necessary to rotate the cover member 10 while it is in contact with the first surface 20A of the mounting member 20.

[0039] <3> In the above embodiment, the recess 22 is provided on the first surface 20A side of the mounting member 20, and the magnet 41 is fitted into this recess 22. However, a recess (not shown) may be provided on the surface of the cover member 10 facing the mounting member 20, and the magnet 41 may be fitted into this recess.

[0040] <4> In the lighting device 1 of the above embodiment, the support member 4 is configured to extend from the end of the lamp 2 on the side opposite the light extraction surface 3. However, the end of the support member 4 on the lamp 2 side may be different from the side on which the light extraction surface 3 is located, and is not limited to being the end of the lamp 2 on the side opposite the light extraction surface 3.

[0041] <5> In the above embodiment, the magnetic force of the magnet 41 is used as a method for rotating the cover member 10 while maintaining the abutting state between the cover member 10 and the first surface 20A of the mounting member 20. However, a method other than the magnet 41 can be adopted as long as it is possible to rotate the cover member 10 while maintaining the abutting state between the cover member 10 and the first surface 20A of the mounting member 20.

[0042] <6> The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail to provide a better understanding of the present invention, and the present invention is not necessarily limited to those having all of the configurations described. The scope of the present invention is defined by the claims, and it is intended to include all modifications within the meaning and scope of the claims. [Explanation of symbols]
