Description

[Technical Field]

[0001] The present invention relates to an illumination device configured with a thin illumination body having a light emitter formed of an organic EL element or the like, and to a lighting support for supporting the thin illumination body. [Background technology]

[0002] Recently, thin illuminators equipped with light emitters such as organic electroluminescent (EL) emitters have been put to practical use (see, for example, Patent Document 1). The thin illuminator described in Patent Document 1 is plate-shaped and has a light-emitting surface incorporating an organic EL light emitter on the front side, which is one side in the thickness direction. Unlike conventional incandescent lamps and fluorescent lamps, such thin illuminators cannot emit light over a range of nearly 360 degrees. Therefore, if you want to illuminate a wide area, for example, both above and below, you need to form a lighting device by combining a thin illuminator with an upward-facing light-emitting surface and a thin illuminator with a downward-facing light-emitting surface. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-186947 Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, an object of the present invention is to provide a lighting device that can illuminate a wide area using a plate-shaped thin lighting body that has a light-emitting surface on one side in the thickness direction, and a lighting support for supporting the thin lighting body. [Means for solving the problem]

[0005] The present invention is an illumination device comprising a plurality of thin-type illumination bodies that are plate-shaped and have a light-emitting surface on one side, that is, the front side, in the thickness direction, and a support portion that supports the plurality of thin-type illumination bodies, wherein the plurality of thin-type illumination bodies are stacked in the thickness direction with the light-emitting surfaces of two of the thin-type illumination bodies facing away from each other to form a set of illumination units, and the support portion comprises an abutment portion that can abut one side of the illumination units in the thickness direction, and a peripheral portion that is located on the outer periphery of the abutment portion in a direction along the light-emitting surface and surrounds all of the illumination units that constitute the illumination device with the outer periphery.

[0006] The present invention also provides a lighting support for supporting a plurality of thin-type lighting bodies that are plate-shaped, square in plan view, and have a light-emitting surface on one side in the thickness direction, that is, the front side, and that has a square frame shape with an L-shaped cross section, and that includes a contact portion that extends horizontally in the L-shape and is capable of contacting from below with the lower of two thin-type lighting bodies stacked vertically with their light-emitting surfaces facing back to back, and a peripheral portion that extends vertically in the L-shape and is located to the sides of the upper and lower of the thin-type lighting bodies stacked vertically.

[0007] According to these configurations, the support portion (lighting support) can reliably support a plurality of thin illuminators with the light-emitting surfaces positioned on both sides of a set of lighting units in the thickness direction.

[0008] The thin illuminator may have a non-emitting frame portion around the light-emitting surface, and the contact portion may contact the frame portion without contacting the light-emitting surface.

[0009] With this configuration, the light emitting surface is not blocked by the contact portion.

[0010] Furthermore, among the surrounding parts, the fixing part that faces the surface of the object to which the lighting device is to be attached is formed larger in the thickness direction of the thin lighting body than other parts, and the fixing part can have a fastener support part that supports a fastener for fixing the lighting device to the object to which it is to be attached.

[0011] According to this configuration, the lighting device can be stably fixed to the object to which it is to be attached using the fixing portion.

[0012] The fixing portion may be plate-shaped, and the fastener support portion may be an elongated hole extending along the thickness direction of the thin-type lighting body.

[0013] According to this configuration, the elongated hole allows the lighting device to be fixed at an appropriate position relative to the object to which it is attached.

[0014] The fixing portion may have an electric wire through hole through which an electric wire for supplying electric power to the plurality of thin illuminators passes.

[0015] This configuration allows the wire to be easily introduced into the lighting device from the outside. [Effects of the Invention]

[0016] According to the present invention, since the support part (lighting support) can reliably support multiple thin lighting bodies, it is possible to provide a lighting device that can illuminate a wide area using a plate-shaped thin lighting body having a light-emitting surface on one side in the thickness direction. [Brief explanation of the drawings]

[0017] [Figure 1] 1 is a perspective view showing an illumination device in an installed state according to an embodiment of the present invention, as viewed from the front and right side. [Figure 2] FIG. 2 is a front-rear longitudinal cross-sectional view showing the lighting device. [Figure 3] 3A and 3B are perspective views showing a support portion of the lighting device as viewed from the front and right side. [Figure 4] FIG. DETAILED DESCRIPTION OF THE INVENTION

[0018] The present invention will be described below with reference to the drawings, taking one embodiment as an example. As shown in Figures 1 and 2, the lighting device 1 of this embodiment comprises a plurality of thin lighting bodies 2 (a total of six, with three bodies stacked two levels above and below) and a support (lighting support) 3 that supports the plurality of thin lighting bodies 2. In this description, the term "thin" refers to a type of three-dimensional shape whose thickness is smaller than its planar dimensions.

[0019] Each thin illuminator 2 is plate-shaped (more specifically, flat) and has a light-emitting surface 21 on the front side, which is one side in the thickness direction. The thin illuminator 2 of this embodiment is quadrangular (more specifically, rectangular) in plan view, and light-emitting elements (more specifically, organic EL elements) are incorporated in the light-emitting surface 21. One or more light-emitting surfaces 21 are provided for each thin illuminator 2 (three light-emitting surfaces 21 arranged side by side in this embodiment). The light-emitting surfaces 21 can be provided on a flat base made of, for example, steel or the like. Each light-emitting surface 21 of this embodiment is square in plan view. The thin illuminator 2 has a non-emitting frame portion 22 around each light-emitting surface 21 in plan view. Furthermore, a board and a switch equipped with circuits for supplying power to the light-emitting elements for light emission and for controlling the light-emitting state are provided on the back side of the thin illuminator 2.

[0020] The plurality of thin illuminators 2-2 are stacked in the thickness direction so that the light-emitting surfaces 21 of the two thin illuminators 2,2 face back to back, thereby constituting a set of illumination unit 2U. In this embodiment, the two thin illuminators 2,2 are stacked one above the other, with the light-emitting surfaces 21 located on the upper surface (see FIG. 1) and the lower surface of the set of illumination unit 2U. The two thin illuminators 2,2 may be directly stacked on top of each other, or a separate member such as a spacer or bracket may be interposed between the two thin illuminators 2,2.

[0021] As shown in Figs. 1 and 2, the support part 3 is attached to the surface of an object W to be attached (more specifically, a wall surface inside a building). As shown in Figs. 3 and 4, the support part 3 has a square frame shape (more specifically, a rectangular frame shape) in a plan view. The dimension between opposing faces of the support part 3 is set to be larger than the outer dimensions of the plurality of thin illuminators 2-2 arranged inside the support part 3. The cross section of the support part 3 in the inward / outward direction (direction perpendicular to the circumferential direction) is L-shaped.

[0022] The support part 3 in this embodiment is integrally formed by appropriately bending and welding a steel plate or the like. However, this is not limited thereto, and the support part 3 may be formed by assembling multiple members by fitting or bolting. The support part 3 may also be formed from various materials such as resin, glass fiber, wood, etc. In this embodiment, the cross section of the entire periphery of the rectangular frame is L-shaped. However, the L-shape may be intermittent as long as it can support the thin-type lighting body 2. The support part 3 includes an abutting part 31 and a peripheral part 32.

[0023] The contact portion 31 is a portion extending laterally in the L-shape and capable of contacting one side (more specifically, the lower side) of the illumination unit 2U in the thickness direction. The portion surrounded by the contact portions 31 provided on all four sides of the support portion 3 is a space, which penetrates vertically in this embodiment. The contact portion 31 is composed of a long-side contact portion 311 provided on the long side of the rectangular shape and a short-side contact portion 312 provided on the short side. In this embodiment, as shown in FIG. 4, the short-side contact portion 312 is formed wider than the long-side contact portion 311. In this embodiment, in relation to the longitudinal dimension of the thin-type illumination body 2, the thin-type illumination body 2 is mainly placed on the long-side contact portion 311, and is placed on the short-side contact portion 312 with a small area or with a gap therebetween.

[0024] The contact portion 31 contacts the frame portion 22 from below without contacting the light-emitting surface 21 of the thin-type lighting body 2. Therefore, the light-emitting surface 21 is not blocked by the contact portion 31, and the illuminance is not reduced by the support portion 3. In this embodiment, the frame portion 22 of each thin-type lighting body 2 is placed on the upper surface of the contact portion 31, and each thin-type lighting body 2 is not particularly fixed to the contact portion 31 and the frame portion 22. However, this is not a limitation, and the thin-type lighting body 2 may be fixed by a screw, adhesive, fastener, or the like.

[0025] The peripheral portion 32 is a portion that extends vertically in the L-shape, is located on the outer periphery of the contact portion 31 in the direction along the light-emitting surface 21, and is a portion that surrounds all of the lighting units 2U to 2U that constitute the lighting device 1. The multiple thin illuminators 2 to 2 are arranged so as to be fitted into the space surrounded by the contact portion 31 and the peripheral portion 32. The peripheral portion 32 in this embodiment is located on the sides of the upper and lower thin illuminators 2, 2 that are stacked in the vertical direction.

[0026] The peripheral portion 32 has a fixing portion 321 that faces the surface (wall surface) of the object W to which the lighting device 1 is to be attached. The fixing portion 321 is plate-shaped (more specifically, flat). The fixing portion 321 is formed larger in the thickness direction of the thin-type lighting body 2 than other portions. The fixing portion 321 of this embodiment is formed larger in the vertical direction than other portions of the peripheral portion 32 (the front side portion and side portion when installed on the object W to be attached), and protrudes upward. With this shape, a large contact area with the surface of the object W can be secured, thereby stabilizing the fixed state to the object W.

[0027] The fixing portion 321 has a fastener support portion 3211 that supports a fastener S (specifically, a screw) for fixing the lighting device 1 to the attachment object W. This allows the lighting device 1 to be stably fixed to the attachment object W using the fixing portion 321.

[0028] The fastener support portion 3211 is a long hole extending along the thickness direction of the thin-type lighting body 2. In this embodiment, two long holes extending in the vertical direction are provided as the fastener support portion 3211 on one end side and the other end side of the fixing portion 321. These long holes enable the lighting device 1 to be fixed to the attachment object W at an appropriate position, particularly in the vertical direction.

[0029] The fixing part 321 also has electric wire through holes 3212 through which electric wires that supply power to the plurality of thin illuminators 2-2 pass. An electric wire C can be arranged as shown in FIG. 1. This makes it easy to introduce the electric wire C from outside into the lighting device 1 in which the sides of the plurality of thin illuminators 2-2 are surrounded by a surrounding part 32. Note that electric wires are connected between the plurality of thin illuminators 2-2, and the power introduced from outside is distributed and supplied to each thin illuminator 2.

[0030] This completes the configuration of the lighting device 1. In the lighting device 1 of this embodiment configured in this manner, the support portion 3 can reliably support the plurality of thin lighting bodies 2-2 with the light-emitting surfaces 21 positioned on both sides of a set of lighting units 2U in the thickness direction. Therefore, the lighting device 1 can illuminate a wide area around the installation location.

[0031] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0032] For example, an organic EL element is incorporated into the light-emitting surface 21 of the slim-type illumination unit 2 in the above-described embodiment, but this is not limitative, and other light-emitting elements such as an LED may also be incorporated.

[0033] Furthermore, the thin illuminator 2 in the above embodiment has a rectangular shape in plan view. However, it is not limited to this and may have other shapes such as a square, parallelogram, rhombus, polygon other than a rectangle (including shapes with rounded corners), circle, oval, ellipse, or a figure with curved edges. In the case of other shapes, the support part 3 is formed along the edge in plan view. Furthermore, the shape of the support part 3 can be variously changed depending on the shape of the thin illuminator 2 as a single unit or an aggregate.

[0034] Furthermore, in the lighting device 1 of the above embodiment, the light emission direction is the vertical direction, but this is not limiting, and the light emission direction may be horizontal or oblique. [Explanation of symbols]
