The storage shelf 11 and the picture rail 12 are arranged at positions where the top faces overlap the winding device 65 and the fixing device 66, respectively, when the surface emitting panel 40 is viewed from the room space 2 side. That is, the winding device 65 and the fixing device 66 are hidden by the storage shelf 11 and the picture rail 12 as shown in FIG. It functions as a hidden member that hides from two sides.

Next, a replacement procedure for replacing the surface emitting panel 40A with a new surface emitting panel 40B will be described.

First, the sheet-side holding portion 62 of the decorative sheet 60 is removed from the fixed-side holding portion 81 of the fixing device 66 to release the engagement between the sheet-side holding portion 62 and the fixed-side holding portion 81 .
At this time, the decorative sheet 60 is cantilevered by the winding device 65 .

Next, the decorative sheet 60 extending from the opening 72 of the winding device 65 is further pulled out from the winding device 65, and the decorative sheet 60 is wound by the winding shaft 71 by the winding force of the winding device 65. ), the surface emitting panel 40 to be replaced is exposed to the indoor space 2 by changing the decorative sheet 60 to the winding attitude.
At this time, most of the decorative sheet 60 is wound up by the winding shaft 71 and stored inside the housing 70 .

As shown in FIG. 9A, the surface emitting panel 40A to be replaced is slid in a predetermined direction with respect to the panel-side mounting member 41, and the panel-side engaging portions 48 and 49 and the mounting-side engaging portions 51 and 52 are engaged. The engagement is released, and the surface emitting panel 40A to be replaced is removed from the panel-side mounting member 41 .
At this time, the raised portion 47 of the surface emitting panel 40A is sandwiched between the attachment-side engaging portions 51 and 52 while being fitted in the opening or recess of the main body plate portion 50 . Therefore, the mounting side engaging portions 51 and 52 restrict movement of the surface emitting panel 40A in one direction.

After removing the surface emitting panel 40A, as shown in FIG. The panel side engaging portions 48 and 49 are attached to the panel side mounting member 41 by inserting the new surface emitting panel 40B into the opening or recess provided in the plate portion 50 and sliding the new surface emitting panel 40B in the direction opposite to the predetermined direction. Engage with the side engaging portions 51 and 52 .

Then, the decorative sheet 60 is pulled out from the opening 72 of the take-up device 65, the sheet-side holding portion 62 of the decorative sheet 60 is engaged with the fixed-side holding portion 81, and the lighting device 10 is in the deployed posture as shown in FIG. 8(a). to

Next, each state of the lighting device 10 when turned off and when turned on will be described.

When the illumination device 10 is turned off, as shown in FIG. 10A, each surface emitting panel 40 is hidden by the decorative sheet 60 and is substantially invisible. Only the seat 60 is visible.
On the other hand, when the illumination device 10 is turned on, the light emitted from the light emitting area 45 of each surface emitting panel 40 is transmitted through the decorative sheet 60 as shown in FIG. Furthermore, not only the directly projected portion of the light emitting area 45 of each surface emitting panel 40 but also the entire area between the decorative sheet 60, the winding device 65 and the fixing device 66 emits light.
Specifically, when the illumination device 10 is turned on, a light emission projection region 85 and a scattered light projection region 86 are formed between the winding device 65 and the fixing device 66 .
The light emission projection area 85 is a bright area in which the light emission area 45 of each surface emission panel 40 is projected directly onto the surface of the decorative sheet 60 on the indoor space 2 side. That is, the light emission projection area 85 has a shape similar to that of the light emission area 45, and has a rectangular shape in this embodiment.
The scattered light projection region 86 is a region other than the light emission projection region 85 , and the light emitted from the light emission region 45 of each surface light emission panel 40 is scattered and becomes scattered light, and the scattered light becomes the indoor space 2 of the decorative sheet 60 . It is a luminous area indirectly projected onto the side surface and is a dark area that is darker than the luminous projection area 85 .
That is, the scattered light projection area 86 is an area in which the light emitted from the light emitting area 45 of each surface emitting panel 40 is irregularly reflected by the gap 67 , diffused, and transmitted through the decorative sheet 60 . The scattered light projection areas 86 are provided around the light emission projection areas 85 and are provided so as to weave between the light emission projection areas 85 . The scattered light projection area 86 includes an area corresponding to the non-light emitting area 46 of the surface emitting panel 40 and an area corresponding to the gap 82 between the module groups 21 .

According to the interior structure 1 of the present embodiment, the lighting device 10 constitutes a pseudo ceiling surface, and when the light is turned off, the surface emitting panel 40 is hidden by the plain decorative sheet 60 and is substantially invisible. Therefore, the ceiling surface is observed as an entirely plain ceiling surface with a sense of unity and a refreshing impression, and the user can feel as if the ceiling surface is a normal ceiling surface. Further, for example, by matching the decorative sheet 60 with the wallpaper or the like of the indoor space 2, the entire indoor space can be given a sense of unity.

According to the interior structure 1 of the present embodiment, when the decorative sheet 60 is turned on, the light emission projection area 85 and the scattered light projection area 86 are formed, and a bright and dark pattern appears between the light emission projection area 85 and the scattered light projection area 86. , accentuate the ceiling surface, and become a lighting device with excellent design that has never existed before.

According to the interior structure 1 of the present embodiment, the plurality of module groups 21 are laid on the base portion 30, and these are covered with the decorative sheet 60 at intervals in the vertical direction (vertical direction, vertical direction).
