  The first lighting device 1 is not particularly limited, but as shown in FIG. 1, the first lighting device 1 may be used by being attached to the indoor side wall surface slightly below the ceiling (used as a bracket). preferable. In the present embodiment, the indoor side wall is a fixed object of the first lighting device 1, and the side wall surface is the mounting surface 6.

As shown in FIGS. 2 and 3, the first lighting device 1 includes a plate-shaped surface light emitting module 10 and a substantially rectangular parallelepiped wall surface fixing member 11, and the surface light emitting module 10 is a wall surface fixing member. 11 is rotatable with respect to 11.
That is, the rotation is performed between a reference posture (see FIG. 3A) where the surface light emitting module 10 is in an upright posture and a post-rotation posture (see FIG. 3C) where the surface light emitting module 10 is lying down. It is possible to move.
In the following description, unless otherwise noted, the direction, the positional relationship of each member, and the like are based on the reference posture.

  In the state where the first lighting device 1 is normally installed in the reference posture, as shown in FIG. 2, the surface light emitting module 10 (specifically, a main body portion of the surface light emitting module 10 described later) is attached to the wall surface fixing member 11. It is located above. More specifically, it is in a state of being positioned above the end portion on the indoor space side of the wall surface fixing member 11 (the end portion located on the side opposite to the indoor side wall surface). In other words, the main body portion of the surface light emitting module 10 and a part of the wall surface fixing member 11 are arranged in parallel in the vertical direction.

  As shown in FIG. 4, the surface light emitting module 10 is formed by overlapping a frame body forming portion 13, a light emitting surface side protective cover 14, a light emitting panel 15 (surface light emitting panel), and a panel back surface protective plate 16. It has become a part.

The frame forming portion 13 includes a standing plate-like frame plate portion 18 that is continuous in a square ring shape when viewed from the front, and a peripheral wall forming portion that protrudes forward (in the thickness direction of the frame plate portion 18) from the peripheral portion of the frame plate portion 18. 19 is formed integrally.
The peripheral wall forming portion 19 covers the end surface of the light emitting panel 15 from the outside, and includes a flat plate-like upper plate portion 13a positioned at the upper end, two vertical plate-like side wall portions 13b facing each other in the left-right direction, and a lower portion. A flat lower plate portion 13 c located on the side is continuous along the peripheral portion of the frame plate portion 18.
The two side wall portions 13b extend to the lower side of the lower plate portion 13c, and a space where the lower side and the front side are open is formed further below the lower plate portion 13c. This space functions as a space for arranging a part of the panel back surface protection plate 16.

Further, in the peripheral wall forming portion 19, the lower plate portion 13c is formed with a notch portion 13d for allowing the cable to pass therethrough. And the attachment hole for inserting fastening elements, such as a screw, in the appropriate part is formed. This mounting hole is a through hole that penetrates the lower plate portion 13c in the thickness direction (vertical direction).
Furthermore, a protruding portion protruding inward is formed on the inner surface of each of the upper plate portion 13a and the two side wall portions 13b (detailed illustration is omitted).
In the present specification, the fastening element is a superordinate concept such as a screw or a nail.

The light emitting surface side protective cover 14 is a plate-like member having translucency, and is a member formed by cutting an appropriate material such as plastic.
Note that, on the main surface on the back side of the light emitting surface side protective cover 14 (the main surface on the frame body forming portion 13 side), the peripheral edge portion is made thinner and thinner than the center side (not shown). That is, on the back side, the central side portion that is quadrilateral in front view is thick, and the peripheral portion surrounding the central side portion is thin in a square ring shape in plan view.

Therefore, when the frame plate portion 18 and the light emitting surface side protective cover 14 are overlapped, a thick portion located on the center side of the back surface of the light emitting surface side protective cover 14 is positioned on the center side of the frame plate portion 18. It will be in the state inserted by the through-hole. Further, the thin portion located on the peripheral edge side of the back surface of the light emitting surface side protective cover 14 is in surface contact with the frame plate portion 18. In this state, the back surface of the frame plate portion 18 and the light emitting surface side protective cover 14 are in a state of forming the same plane, and one main surface of the surface light emitting module 10 (the back surface is the side wall surface of the room when attached in the standard posture). Side surface) is formed.
That is, the thick part located in the center side of the light emission surface side protective cover 14 is located in the part enclosed by the frame board part 18 at the upper side, the side, and the downward direction. In addition, the inner peripheral surface of the through hole located on the center side of the frame plate portion 18 is in contact with the end surface of the thick portion without any gap (or almost without any gap). And the same plane where the back of a thick part and the back of frame board part 18 continue without a level difference (or without a level difference) is formed.
Note that “substantially” of “substantially without a gap” includes a minute error, and the same applies to other cases.

  The light-emitting panel 15 is a surface light-emitting panel that spreads in a planar shape and can emit planar light, and is a panel that can be dimmed. Specifically, the light-emitting panel 15 is a member formed by attaching a frame member 21 to the panel body 20.

The structure includes a side substrate 24.

  The power feeding part 23 is a part for electrically connecting the organic functional layer and the panel side substrate 24, and is a part for applying a voltage between the anode layer and the cathode layer. The power feeding unit 23 extends from the inner side to the outer side, and a part thereof protrudes from the back surface of the panel body 20. In other words, the portion exposed to the outside is supported in a cantilevered manner on the back surface of the panel body 20.

  The light emitting panel 15 is preferably an organic EL panel having a light emitting surface on one main surface side as described above from the viewpoint of being lightweight and thin. By adopting the organic EL panel, it is possible to easily obtain illumination light having excellent characteristics such as softness and high color rendering properties, and it is also possible to irradiate diffuse light. The light emitting panel 15 may be a flexible panel having flexibility.

The protective plate main body 28 is integrally formed with a thin plate-like portion 28a in an upright posture and a raised portion 28b that protrudes from the back of the thin plate-like portion 28a to the rear (from the light emitting panel 15 side surface to the light emitting panel 15 side). It is the part which was done.
The raised portion 28b is a portion raised so that the shape in front view is substantially concave, and the upper end surface thereof is located below the upper surface of the thin plate-like portion 28a. And each of the both ends is in the state located in the center side in the left-right direction rather than the both ends of the thin-plate-shaped part 28a.

Here, a protrusion protruding upward is formed at a position away from the thin plate portion 28a rearward (frontward in FIG. 6) on the upper surface of the raised portion 28b. For this reason, an engagement groove 33 that is depressed downward is formed between the raised portion 28b and the thin plate-like portion 28a in the upper end portion of the protection plate main body 28.
In addition, an engagement groove portion 33 extending downward from the upper end is also formed on each of both side surfaces of the raised portion 28b that are opposed to each other in the left-right direction. The engagement groove portion 33 formed on the side surface is a groove that is recessed inward (center side in the left-right direction) from the periphery, and is a groove that has a substantially square cross section and extends in the vertical direction.

  In addition, the central portion in the left-right direction of the protection plate main body 28 (the raised portion 28b) is a portion that is thinner than the surroundings and is a recessed portion that is recessed toward the front side (the thin plate portion 28a side). Is formed. This board | substrate arrangement | positioning part 34 is a groove-shaped part which forms the space extended in an up-down direction with a square cross-sectional shape.

A hole 29a is formed.
Both the mounting hole and the cable insertion hole 29a are through-holes that penetrate the bottom plate forming portion 29 in the thickness direction (vertical direction). The mounting hole has a circular opening shape, and the cable insertion hole 29a has a substantially rounded rectangular shape with the opening shape extending in the left-right direction.

The movable piece portion 30 is a portion extending from a portion on the center side in the left-right direction in the protruding end surface of the bottom plate forming portion 29 (the end surface on the light emitting panel 15 side, the front end surface in FIG. 6).
The movable piece 30 includes a flat plate portion 30a protruding in the same direction as the protruding direction of the bottom plate forming portion 29 (the rear side and the front side in FIG. 6), and a lower portion (protective plate) from the protruding end of the flat plate portion 30a. A standing plate-like portion 30b protruding in a direction away from the main body portion 28 is integrally formed. That is, it is a plate-like portion whose side view is substantially L-shaped.
A mounting hole for inserting the fastening element is formed in an appropriate portion of the upright plate-like portion 30b. This mounting hole is a through hole that penetrates the upright plate-like portion 30b in the thickness direction (front-rear direction).

In addition, the side end face of the surface light emitting module 10 is not located above the rear (the wall surface side of the room when attached).
In more detail, the side end surface of the surface emitting module 10 is located at a position away from the side end surface of the wall surface fixing member 11 at each of both ends in the left-right direction. That is, a gap is formed between the side end surface of the case main body 50 and the side end surface of the surface emitting module 10.

  That is, the lower surface of the main body portion of the surface light emitting module 10 and the upper surface of the wall surface fixing member 11 (the upper surface of the case main body portion 50, which is a surface orthogonal to the indoor side wall surface when attached, Are parallel to each other. More specifically, the lower surface of the main body portion of the surface emitting module 10 and the upper surface of the wall surface fixing member 11 are opposed to each other, and a space (gap) is formed therebetween. This gap is a gap through which a small amount of light leaks from the space formed between the mounting surface 6 and the surface emitting module 10 when the surface emitting module 10 emits light in the reference posture.

Here, when it is set to a reference posture at the time of attachment, a substantially rectangular parallelepiped space is formed between the indoor side wall surface (see attachment surface 6, FIG. 2, etc.) and the surface emitting module 10. Yes. Therefore, when the surface emitting module 10 emits light in the reference posture, the surface emitting module 10 emits light toward this space.
More specifically, this space is a large part on the front side (a part excluding a part on the lower end side, and excludes a gap formed between the main body part of the surface emitting module 10 and the wall surface fixing member 11. The portion is a space where the surface light emitting module 10 is closed, and the rear side is closed by an indoor side wall surface. In addition to this, the lower side is a space closed by the wall surface fixing member 11.
That is, the boundary surface (boundary portion) serving as the boundary between this space and the outside is a surface orthogonal to the main surface on the light emitting surface side of the surface light emitting module 10 and the side wall surface in the room. One of the boundary surfaces is located on the ceiling side (upward) at the time of attachment, and is located on the same plane as the upper end surface of the surface emitting module 10 that is the upper end surface of the first lighting device 1.
Furthermore, the other boundary surface (the other two boundary surfaces) is a surface orthogonal to the boundary surface located above, and is located on the same plane as the side end surfaces of the surface emitting module 10 and the wall surface fixing member 11. Yes. As described above, the space formed between the indoor side wall surface and the surface emitting module 10 through the boundary surface that is a plurality of continuous boundary surfaces and orthogonal to the other boundary surfaces at the adjacent positions, and the outside. Is in a continuous state.

  In addition, when the 1st lighting device 1 is attached to the side wall surface of the room from the ceiling, the space which becomes a living space of the person is the opposite side to the side wall surface of the room on the basis of the first lighting device 1, and the lower side. It becomes the position. In the first illuminating device 1 of the present embodiment, in the reference posture, the front of the space formed between the indoor side wall surface and the surface light emitting module 10 (the side opposite to the wall surface and the indoor space side) and most of the lower part are It is blocked and can be suitably used as indirect illumination.

In addition, as described above, the first lighting device 1 can take a post-rotation posture in which the surface light emitting module 10 is turned sideways by rotating the surface light emitting module 10 from the reference posture. (See FIGS. 3 and 17).
Specifically, as described above, the surface light emitting module 10 is rotatable with respect to the wall surface fixing member 11. At this time, as shown in FIG. 17, an angle θ between the light emitting surface of the surface light emitting module 10 in the reference posture and the light emitting surface of the rotated surface light emitting module 10 is in a range where the angle θ is 0 degree or more and 90 degrees or less. Rotates as a range of motion. Note that the upper limit of the movable range includes an error of about several degrees.
In other words, the post-rotation posture is a posture in which the surface emitting module 10 is moved to the maximum from the reference posture, and is a posture rotated by 90 degrees. Further, the surface light emitting module 10 can not only be moved to the maximum, but also can be maintained in a state of being rotated by a predetermined angle within the movable range.

  The surface light emitting module 10 is maintained in a state where the side end surface of the surface light emitting module 10 and the side end surface of the wall surface fixing member 11 are located on the same plane in any position within the movable range. . Therefore, the state where they are located on the same plane is maintained during the rotation as well.

  In the post-rotation posture, the main surface including the light emitting surface of the surface light emitting module 10 (the back surface in the reference posture) and the upper surface of the wall surface fixing member 11 are in the same plane. Further, the side end surface (the lower surface in the reference posture) on the wall surface fixing member 11 side in the main body portion of the surface emitting module 10 is in a state of being opposed to the outer surface (front surface) of the wall surface fixing member 11. That is, these surfaces are all parallel to the indoor side wall surface (mounting surface 6), and a space is formed between them.

More specifically, in the reference posture, the surface (in FIG. 11 etc.) in which the inner and outer communication holes 80b and the movable piece mounting holes 80c are formed among the end faces in the short direction of the connecting rod portion 80 is indoors. It will be in the state which faced the side wall surface side (rear side) (refer FIG. 13 etc.). Then, the curved surface side faces the indoor space side (front side).
On the other hand, in the post-rotation posture, the surface on which the inner and outer communication holes 80b and the movable piece mounting holes 80c are formed faces upward (see FIGS. 11, 17, etc.). And it will be in the state where the curved surface side faced the lower side (area | region partition plate part 72 side).

Further, in the reference posture, the entire area of the main body portion of the surface emitting module 10 is located above the front end portion of the wall surface fixing member 11 (see FIG. 2 and the like). Therefore, when viewed from above (when viewed from above or below), the surface light emitting module 10 is in a state of overlapping the front end side portion of the wall surface fixing member 11.
That is, when the surface emitting module 10 is projected onto the upper surface of the wall surface fixing member 11, at least a part of the projection surface (the entire area in the present embodiment) is in a state of overlapping the upper surface of the wall surface fixing member 11.

On the other hand, in the post-rotation posture, the entire area of the main body portion of the surface light emitting module 10 is located in front of the front end surface of the wall surface fixing member 11 (see FIG. 3C and the like). Therefore, when viewed from above (when normally installed and viewed from above or below), the main body portion of the surface light emitting module 10 does not overlap the wall surface fixing member 11. In other words, the surface emitting module 10 is in a state where only a part of the movable piece 30 overlaps the wall surface fixing member 11.
That is, when the main body portion of the surface light emitting module 10 and the wall surface fixing member 11 are projected onto surfaces that are perpendicular to the vertical direction, the two projection surfaces do not overlap.

By the way, since the light source of the surface emitting module 10 emits surface light, even in the post-rotation posture in which the light emitting surface faces the ceiling side (upward), a part of the light radiated to the outside is the indoor side wall surface (mounting surface 6). ) Is illuminated. From this, when the surface emitting module 10 is moved within the movable range, the side surface (mounting surface 6) is illuminated in any state.
That is, in the reference posture, the light emitting surface faces the indoor side wall surface, and the side wall surface is illuminated. Further, when the posture is shifted from the reference posture to the post-rotation posture, the light emitting surface gradually turns upward, and the upper side of the side wall surface is strongly illuminated. And when it rotates a predetermined angle, it will be in the state where the boundary part vicinity of a side wall surface and a ceiling was strongly illuminated. Even in a state where the light emitting surface faces the ceiling, as described above, the ceiling is strongly illuminated and the indoor side wall surface is also illuminated.
That is, when the first lighting device 1 emits light, the mounting surface 6 is always illuminated.

Moreover, as for the 1st lighting apparatus 1, a part of board | substrate 41 with a button is exposed outside, and the operation button is formed (refer FIG. 2 etc.). This operation button functions as a power button for switching between a light emitting state in which the light emitting surface of the surface light emitting module 10 emits light and a non-light emitting state in which light is not emitted, and increases or decreases brightness (light quantity) in the light emitting body. It also functions as a dimming button.
That is, when the surface emitting module 10 is not emitting light, the operation button is pressed to shift to the light emitting state, and the brightness (light quantity) increases (or decreases) every time the operation button is pressed. Then, when the operation button is pressed when light is emitted at a predetermined brightness in the light emitting state, the light emitting state is shifted to the non-light emitting state.
Such switching between the light emitting state and the non-light emitting state and the light control are also possible by operating an external operation device.

  Next, the second lighting device 2 will be described. In addition, about the part similar to the above-mentioned 1st illuminating device 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  Although the second lighting device 2 is not particularly limited, as shown in FIG. 1, the second lighting device 2 can be used as a spotlight that illuminates a predetermined portion of the indoor space (for example, a painting or a hanging shaft attached to a wall surface). ing. It can also be used as direct lighting, and can also be used as a bracket or footlight.

As shown in FIG. 18, the second lighting device 2 includes a thick plate-like surface light emitting module 110 and a wall surface fixing member 111, and has a substantially L-shaped side view.
As shown in FIG. 18, the surface emitting module 110 has a structure that can rotate with respect to the wall surface fixing member 111. At this time, in the first lighting device 1 described above, the rotation axis is a straight line extending in the left-right direction (a straight line perpendicular to the side end surface of the first lighting device 1), whereas in the second lighting device 2, the vertical axis is vertical. It is a straight line extending in the direction (a straight line perpendicular to the upper surface or the lower surface of the second lighting device 2). That is, from the reference posture (see FIG. 19A) in which the main surface on the light emitting surface side of the surface light emitting module 110 faces the rear side (the side wall surface side of the room at the time of attachment), the front side (the indoor living space side at the time of attachment). ) Can be rotated between post-rotation postures (see FIG. 19C).
In the following description, unless otherwise noted, the direction, the positional relationship of each member, and the like are based on the reference posture.

  As shown in FIG. 20, the surface light emitting module 110 is a portion formed by overlapping a frame body forming portion 113, a light emitting surface side protective cover 14, a light emitting panel 15, an attachment plate member 116, and a back plate 117. It has become.

A plurality (two) of the frame-side fixing pieces 121 are provided, all of which are located slightly above the lower end of the frame plate portion 118, one on one end side in the left-right direction and the other on the other end side. One is formed.
The frame-side fixing piece 121 is a substantially L-shaped part protruding inward from the inner side surface of the frame plate part 118, and a part thereof is in contact with the side wall part 113b. An attachment hole for inserting the fastening element is formed, and this attachment hole is a through hole that penetrates the side wall portion 113b in the thickness direction (vertical direction).

As shown in FIG. 20, the accessory plate member 116 is disposed so as to be attached to a main surface of the light-emitting panel 15 to which the panel-side substrate 24 (see FIG. 4 and the like) is attached. It is a vertical plate-like member. A recessed portion that is recessed toward the back plate 117 side (front side) is formed on the light emitting panel 15 side (rear side) surface of the accessory plate member 116.

Further, the upper projection 130 and two lateral projections projecting from the peripheral portion on the back surface (the surface on the light emitting panel 15 side and the front surface in FIG. 22) of the main body plate portion 117a to the rear side (the light emitting panel 15 side). It has a structure having a part 131 and a lower protruding plate part 132.

The upper protruding portion 130, the two side protruding portions 131, and the lower protruding plate portion 132 are continuously connected in a square ring shape along the peripheral edge portion of the main body plate portion 117a. At this time, the upper protrusion 130 and the two side protrusions 131 are both rectangular parallelepiped parts, and the lower protruding plate part 132 is a flat part. That is, the lower protruding plate portion 132 is a portion having a longer protruding length than the upper protruding portion 130 and the side protruding portion 131.
Further, an upper protrusion 130 a protruding upward is formed on the upper surface of the upper protrusion 130.

The lower protruding plate portion 132 is provided with a notch groove portion 132a for inserting a shaft portion 150 (see FIG. 23 and the like described later in detail). Further, a plurality of mounting holes through which the fastening elements are inserted are formed, each serving as a hole penetrating the lower protruding plate portion 132 in the thickness direction.
The mounting holes located around the notch groove 132a are holes for mounting the shaft coupling plate 165 (described in detail later), and are located in the vicinity of both ends in the longitudinal direction (left-right direction) of the lower protruding plate 132. Each mounting hole is a hole for mounting the frame forming portion 113. FIG. 22 shows a state in which the fastening element is inserted for convenience of drawing.

The main body plate portion 117a is formed with an interval maintaining piece 117b at an appropriate portion. The interval maintaining piece 117b is a portion that comes into contact with the accessory plate member 116 (see FIG. 20) from the front, and more specifically, contacts with a surface of the principal surface of the accessory plate member 116 on which no depression is formed. Part.
At least one of the interval maintaining pieces 117b is a rectangular flat plate-like portion extending in the left-right direction, and at least one other is a vertical plate-like portion extending in the vertical direction. Each of these is a portion that protrudes backward from the main body plate portion 117a (on the side of the accessory plate member 116 and forward in FIG. 22), and the protruding length is the same (substantially the same). That is, it can be said that the interval maintaining piece 117b is a portion where the protruding end surface is in contact with the accessory plate member 116.

The wall surface fixing member 111 is a member whose side view shape is substantially L-shaped as shown in FIG. That is, a thick plate-like main body portion 111a that protrudes indoors from the side wall surface of the room at the time of attachment, and a bulge that protrudes upward on the protruding end side (the front end side, the indoor space side at the time of attachment) of the main body portion 111a. The structure has a portion 111b. In other words, the raised portion 111b protrudes in a direction perpendicular to the upper surface or the lower surface (surface parallel to the protruding direction) of the main body portion 111a.
The front surface (the outermost surface) of the main body 111a and the front surface of the raised portion 111b are formed by the same surface, and are the front surfaces of the wall surface fixing member 111 and are the outermost surfaces. A member outer surface 196 is formed.
Further, the upper surface of the main body 111a and the lower end of the back surface of the raised portion 111b (the surface located on the side of the side wall surface when attached) are in a continuous state via a curved surface.
The rear end surface of the main body portion 111a is formed with an attachment hole that is used as needed when attaching to the indoor side wall surface. The attachment hole extends in the thickness direction (front-rear direction). It is a through hole that penetrates.

  As shown in FIG. 22, the wall surface fixing member 111 is formed by housing each member in a housing. As main components, the board 141 with buttons, the control board 42, the movable mechanism 145, the power A source storage box 146 is stored.

Similarly to the above-described substrate 41 with a button, the substrate with button 141 is a substrate provided with a button forming portion and a connector for cable connection. The button forming part is a part that generates a signal when pressed, and includes a switch part electrically connected to the substrate body, an elastic member such as rubber, a button cover exposed to the outside, and the like. It has a structure.
The button-equipped substrate 141 is attached in an upright posture, is located near the side surface of the casing of the wall surface fixing member 111, and a part of the button cover extends from a through hole for button insertion formed on the side face of the casing. An operation button is formed by exposure (see FIG. 18).
In addition, the shape of each part of a button formation part differs from the thing of the board | substrate 41 with a button mentioned above.

  The control board 42 is in a state in which it is placed on its side so that its thickness direction is the same as the vertical direction.

  As shown in FIG. 23, the movable mechanism unit 145 includes a shaft unit 150, a movable range regulating unit 151, and a connecting plate unit 152. The movable range restricting portion 151 has a structure having a shaft interlocking portion 153 and a rotation restricting member 154.

The shaft portion 150 is a cylindrical member extending in the vertical direction in an upright posture, and has a hollow portion into which a cable can be inserted. This hollow portion is a hole penetrating from the upper surface to the lower surface of the shaft portion 150, has an opening shape that is circular, and extends with the same diameter and the same axis.
Further, a gear portion 150a is formed on the outer peripheral surface on one end side in the longitudinal direction of the shaft portion 150 and in the vicinity of the lower end side. The gear portion 150 a is formed with external teeth that are arranged in parallel at a predetermined interval in the circumferential direction of the shaft portion 150. In other words, the longitudinal grooves arranged in parallel with a predetermined interval in the circumferential direction are formed over the entire circumference, and the teeth are formed between the longitudinal grooves extending in the vertical direction.

  In the upper end portion of the shaft portion 150, in order from the lower side, a flange-shaped portion, a portion having an outer shape that is narrower in diameter than the flange-shaped portion, and a portion having an outer shape located on the upper end side are cylindrical. Has a continuous shape. And the latching recessed part 150b which is a part recessed toward the inner side is formed in a part of outer peripheral surface of a cylindrical part. The latching recess 150b is a portion that is recessed inward from the periphery and extends in the vertical direction.

The shaft interlocking portion 153 has a shape including a thick plate-like main body portion 153a having a substantially circular shape in plan view, and a rectangular parallelepiped regulating protrusion 153b protruding outward from a part of the side surface of the main body portion 153a. Yes.
The side surface of the main body portion 153a is continuous in an annular shape, and a gear portion 158 is formed in a part thereof. The gear portion 158 is a portion where external teeth are arranged in parallel at a predetermined interval in the circumferential direction of the side surface, and is a portion that meshes with the gear portion 150a described above. In addition, the regulation protrusion 153b protrudes outward from a part of the side surface that is different from the gear portion 158.

  The rotation restricting member 154 is formed at a position away from the main body portion 153a of the shaft interlocking portion 153, and has a structure including an upright wall portion 159 extending intermittently along the circumferential direction of the side surface of the main body portion 153a. Yes. That is, each of the standing wall portions 159 is formed by a plurality of standing wall portions 159a extending in the circumferential direction of the side surface of the main body portion 153a, and an end portion in the extending direction of one standing wall portion 159a and the other standing wall portion 159a are extended. A missing portion 154b is formed between the end portions in the direction.

The connecting plate portion 152 is a flat member, and one end side is placed on the upper surface of the main body portion 153a in the shaft interlocking portion 153, and the other end side is positioned outside the main body portion 153a. A shaft insertion hole that penetrates the connecting plate portion 152 in the thickness direction (vertical direction) is formed on the other end side, and the shaft portion 150 is inserted.
That is, the connecting plate portion 152 functions as a separation preventing member that prevents the shaft portion 150 and the shaft interlocking portion 153 from separating.

In the movable mechanism portion 145, the gear portion 150a of the shaft portion 150 and the gear portion 158 formed on the main body portion 153a of the shaft interlocking portion 153 are in mesh with each other. Further, the restricting projection 153 b of the shaft interlocking part 153 is in a state of being located at the missing part 154 b of the rotation restricting member 154.
For this reason, when the shaft portion 150 rotates around the vertical axis, the body portion 153a of the shaft interlocking portion 153 rotates accordingly, and the restricting projection portion 153b moves clockwise or counterclockwise in plan view. And the further movement of the control projection part 153b is blocked | prevented because the control projection part 153b contact | abuts the edge part in the extending direction of any standing wall part 159a.
That is, the shaft portion 150 is attached in a state where rotation of a predetermined amount or more in the same direction is restricted. As a result, when the surface emitting module 110 is rotated (see FIG. 19, details will be described later), the movable range is limited.

The power source storage box 146 is a portion in which the power supply unit 44 described above is stored (not shown in FIG. 22, see FIG. 4 and the like). That is, the second lighting device 2 of the present embodiment also has a structure including the power supply unit 44.
The power source storage box portion 146 has a structure including a cable insertion portion 146a (one side is not shown) for drawing a cable (cable portion 91) from the inside to the outside on each of both side surfaces. The cable insertion portion 146a is a portion that communicates the internal space of the power source storage box portion 146 with the outside. That is, the internal space of the power source storage box portion 146 and the second lighting device 2 are formed by overlapping the cable insertion portion 146a and the missing portion formed on the side wall surface of the casing of the wall surface fixing member 111 inside and outside. A hole-like portion that communicates with the outside is formed.

  In addition, although illustration is abbreviate | omitted, the cable insertion hole which connects the internal space of the power source storage box part 146 and the space in which the control board 42 was installed in the power source storage box part 146 is formed. In addition, a latching protrusion for latching a part of the cable (cable 91) is formed inside the power source storage box 146.

  Here, in the second lighting device 2 of the present embodiment, as shown in FIG. 22, the shaft connecting plate 165 is attached to the upper end side of the shaft portion 150, and this shaft connecting plate 165 is below the back plate 117. It is attached to the side protruding plate part 132. Accordingly, the surface light emitting module 110 is attached to the wall surface fixing member 111 so as to be rotatable via the movable mechanism portion 145.

The shaft connecting plate 165 is a flat plate-like member extending in the left-right direction, and an insertion hole for inserting the upper end portion of the shaft portion 150 is formed on the center side in the longitudinal direction. This insertion hole is a through-hole penetrating the shaft connecting plate 165 in the thickness direction, and a protrusion (not shown) protruding inward is formed on a part of the inner peripheral surface.
That is, by inserting the upper end portion of the shaft portion 150 into the insertion hole and inserting the protrusion formed on the inner peripheral surface of the insertion hole into the latching recess 150b (see FIG. 23), the shaft coupling plate 165 is It can be attached to the shaft portion 150 in a non-rotatable state.

  In this state, the portion slightly below the upper end of the shaft portion 150 is positioned inside the notch groove portion 132a, and a part of the lower surface of the shaft connecting plate 165 is placed on the upper surface of the lower protruding plate portion 132, The shaft connecting plate 165 and the lower protruding plate portion 132 are integrally fixed via a fastening element or the like.

As described above, in the surface light emitting module 110, the light emitting surface side protective cover 14, the light emitting panel 15, and the accessory plate member 116 are overlapped on the frame portion formed by the back plate 117 and the frame body forming portion 113. It is a member formed by accommodating the formed laminate (see FIG. 20).
That is, the upper protrusion 130a (see FIG. 22) of the back plate 117 is inserted into a recess (not shown) formed on the inner surface of the upper plate portion 113a (see FIG. 21) of the frame body forming portion 113. . In addition, the frame body side fixing piece 121 of the frame body forming portion 113 is placed on the upper surface of the lower protruding plate portion 132, and the fastening element is inserted therethrough. As a result, the back plate 117 and the frame body forming portion 113 are fixed, and the frame portion is formed.

At this time, the cable extending from the panel side substrate 24 is drawn into the housing of the wall surface fixing member 111 through the inside of the shaft portion 150 and is connected to the control substrate 42.
Further, the control board 42 and the button-equipped board 141, and the power supply part 44 housed inside the control board 42 and the power source storage box part 146 are also electrically connected via a cable.

Also in the surface emitting module 110, one main surface (rear side surface) is a surface including a light emitting surface that emits light, and is divided into a region that emits light and a region that does not emit light.
That is, this surface is a surface formed by the frame plate portion 118 and the thick portion of the light emitting surface side protective cover 14, and the thick portion of the light emitting surface side protective cover 14 is the light emitting region of the panel body 20 described above. It becomes a part which overlaps with 20a. From this, among the one main surface of the surface light emitting module 10, it is a part formed by the light emission surface side protective cover 14, and the area | region located in the center side becomes the area | region (light emission surface) which light-emits. And it is a part which encloses the outer side of this light emission area | region, and the part from the edge which continues in a square ring shape by front view becomes a surface which does not emit light itself.
The main surface having the light emitting surface is formed by fitting the thick portion of the light emitting surface side protective cover 14 into a through hole located at the center of the frame plate portion 118. That is, it is a single flat surface formed by the rear surface of the frame plate portion 118 and the rear surface of the thick portion of the light emitting surface side protective cover 14 and having no irregularities (substantially without irregularities).

And the other main surface (front side surface) of the surface emitting module 110 is a surface which becomes the back surface side of one main surface, and is a surface located on the opposite side so as to be spaced apart from one main surface. . This surface is a surface formed by the front side surface of the back plate 117, in other words, a surface formed by one member.
Here, as described above, the back plate 117 and the frame body forming portion 113 form a frame portion without inserting a fastening element in a direction orthogonal to the main surface. Therefore, the other main surface of the surface emitting module 110 is in a state in which a fastening element such as a screw is not positioned and a flat surface is formed without any unevenness.

Also in the second lighting device 2, the module outer surface 195, which is the outermost surface of the surface light emitting module 110 (the indoor side at the time of attachment), and the outermost surface of the wall surface fixing member 111 in the reference posture. A certain fixed member outer surface 196 is located on the same plane (see FIGS. 19 and 24).
At this time, the fixing member outer surface 196 is also in a state in which a fastening element such as a screw is not located and a flat surface is formed without unevenness.

At this time, the main surface having a light emitting surface which becomes the rear surface of the surface light emitting module 110 (the surface on the side wall surface in the room at the time of attachment) and the upper portion of the rear surface of the raised portion 111b are also located on the same plane. It has become.
Therefore, when viewed in plan in the reference posture (when normally installed and viewed from above or below), the upper surfaces of the surface light emitting module 110 and the raised portion 111b are overlapped in the entire region (substantially the entire region).

  As described above, when the overall outer shape of the third lighting device 3 is a substantially rectangular parallelepiped shape, there is no undulating unevenness when viewed from any direction when installed in the room, and it has a beautiful shape that does not stand out in the room. Can do.

As with the first lighting device 1 described above, the third lighting device 3 takes a post-rotation posture in which the surface light emitting module 210 is turned sideways by rotating the surface light emitting module 210 from the reference posture. (See FIG. 26C).
The first lighting device 1 differs in that the light emitting surface of the surface light emitting module 10 faces upward in the post-rotation posture, whereas the third lighting device 3 differs in that the light emitting surface faces downward. Yes. For this reason, when the third lighting device 3 is attached to the lower side of the indoor wall and used as a footlight that illuminates the indoor floor space, if it is in a post-rotation posture, it becomes indirect illumination that irradiates light toward the floor surface. .

That is, the 3rd lighting device 3 can also rotate the surface emitting module 210 with respect to the wall surface fixing member 211, as FIG. 26 shows. Then, the angle θ formed by the light emitting surface of the surface light emitting module 210 in the reference posture and the light emitting surface of the surface light emitting module 210 after the rotation is rotated as a movable range. (See FIG. 34).
Also in the third illuminating device 3, the surface light emitting module 210 can not only be moved to the maximum, but can also be maintained in a state of being rotated by a predetermined angle within the movable range.

  It should be noted that the surface light emitting module 210 is maintained in a state where the side end surface of the surface light emitting module 210 and the side end surface of the wall surface fixing member 211 are located on the same plane in any position within the movable range. . Therefore, the state where they are located on the same plane is maintained during the rotation as well.

In the first lighting device 1 described above, an example is shown in which the surface light emitting module 10 and the wall surface fixing member 11 are connected by a movable part formed by the movable piece part 30 and the movable mechanism part 52. In the second lighting device 2, the movable mechanism portion 145 and the shaft connecting plate 165 are connected by a movable portion, and in the third lighting device 3, the movable mechanism portion 252 that functions as a movable portion is connected.
However, the surface light emitting module and the wall surface fixing member may be connected via a universal joint (universal joint) instead of such a connection structure.
In this case, not only a straight line extending in the left-right direction or a straight line extending in the up-down direction can be rotated as a rotation center axis, but a plurality of straight lines extending in different directions can be rotated in various directions as a rotation center axis. It becomes possible.

For example, as shown in FIG. 35, a thick plate-like surface light emitting module 410 and a substantially rectangular parallelepiped wall surface fixing member 411 may be connected by a universal joint portion 412 (movable portion).
The surface light emitting module 410 and the wall surface fixing member 411 have the same structure as that of the first lighting device 1 described above except for the movable portion and the peripheral portion.
Specifically, in order to fix the lower end portion of the surface emitting module 410, a plate-like joint mounting base portion (not shown) protruding inwardly is formed on the inner side surface of the case portion 440, and on the upper surface of the case portion 440. The point etc. which formed the joint part insertion hole which connects inside and outside differ. Moreover, the point etc. which the joint attachment part for fixing the upper end side of the universal joint part 412 in the lower part of the surface emitting module 410 were formed differ.

  Thus, when it is made the structure connected by the universal joint part 412, in addition to the operation | movement rotated about the straight line extended in the left-right direction like the above-mentioned 1st illuminating device 1, the straight line extended to an up-down direction is a rotation axis line. Can be rotated. Furthermore, it is possible to rotate the surface emitting module 410 so as to be tilted forward (inside the room at the time of attachment) in a posture in which the surface emitting module 410 is rotated by a predetermined angle with a straight line extending in the vertical direction as a rotation axis. . Further, it is possible to rotate the straight line extending in the left-right direction as the rotation center axis while rotating the straight line extending in the vertical direction as the rotation axis.

Furthermore, as shown in FIG. 36, a thick plate-shaped surface light emitting module 510 and a wall surface fixing member 511 having a substantially L-shaped side view may be connected by a universal joint portion 512 (movable portion). .
The surface light emitting module 510 and the wall surface fixing member 511 have the same structure as that of the above-described second illumination device 2 except for the movable portion and its peripheral portion.
Specifically, in order to fix the lower end portion of the surface emitting module 510, a difference is that a joint mounting base (not shown) is formed inside the casing of the wall surface fixing member 511. In the second lighting device 2 described above, the cable extending from the panel side substrate 24 is inserted into the shaft portion 150. However, the second lighting device 2 is different in that the cable is extended at a position away from the universal joint portion 512. Yes. That is, the cable insertion portion 513 formed by the through hole that penetrates the lower surface of the surface emitting module 510 and the through hole that penetrates the upper surface of the wall surface fixing member 511 is formed at a position away from the universal joint portion 512 that is a movable portion. It is different in point. Moreover, the point etc. which the joint attaching part for fixing the upper end side of the universal joint part 512 to the lower part of the surface emitting module 510 were formed differ.

  Thus, when it is made the structure connected by the universal joint part 512, in addition to the operation | movement which turns a straight line extended in an up-down direction as a rotation center axis line like the above-mentioned 2nd illuminating device 2, the straight line extended in a left-right direction is a rotation axis line. Can be rotated. Further, it is also possible to rotate with a straight line that intersects with the upper surface of the surface light emitting module 510 and the lower surface of the wall surface fixing member 511 and extends obliquely as a rotation axis.

Moreover, when it is set as the structure connected via a universal joint part, you may provide the operation control part for restrict | limiting the movable range of a surface emitting module.
For example, in the wall surface fixing member 511, a plate-like body portion 511a protruding upward from the upper surface may be provided on the thick plate-like main body portion 511a that protrudes indoors from the side wall surface of the room at the time of attachment. In other words, when the surface light emitting module 510 tries to rotate beyond the movable range, the surface light emitting module 510 may be in contact with the plate-like portion to prevent further rotation. Moreover, it is good also as a rod-shaped body formed with elastically deformable materials, such as rubber | gum, instead of a plate-shaped member from a viewpoint of preventing the damage by contact | abutting.

Further, the above-described lighting device has a structure in which the surface light emitting module automatically rotates as a structure having a power transmission mechanism such as a motor, a gear, and a clutch functioning as a power source generation unit inside the wall surface forming member. Also good.
For example, in the first illuminating device 1 described above, instead of the movable mechanism portion 52, a rod-like member having substantially the same shape as the connecting rod portion 80 is fixed to a shaft interlocking with the rotation of the motor, and surface emission is performed on the rod-like member. The module 10 may be fixed. As another example, in the second lighting device 2 described above, instead of the movable mechanism portion 145, a gear interlocking with the rotation of the motor and the shaft portion 150 may be engaged.

  Such an illuminating device can be switched between a light emitting state and a non-light emitting state, a dimming operation, and a surface emitting module rotating operation (light irradiation direction changing operation) by pressing an operation button of an external operation device. It has a structure. For example, by operating an external operation device, the surface light emitting module can be automatically rotated to switch between a state in which the indoor side wall surface is directed and a state in which the ceiling surface is directed.

And in the state which attached the several illuminating device indoors (refer FIG. 1 etc.), by operating an external operation apparatus, the surface emitting module of each illuminating device faces the predetermined direction, and is predetermined. It is possible to adjust all at once so as to emit light with a given brightness.
Specifically, for each lighting device, the lighting state or non-lighting state, the brightness when the light emitting state is set, the direction of the light emitting surface of the surface emitting module, etc. are set. This setting information is stored in advance in the storage means.
Note that this storage means only needs to be provided in any one of a plurality of lighting devices and external operation devices, and may be a memory mounted on any of the substrates incorporated therein.
Then, when the external operation device is operated, each lighting device performs various operations (switching operation between light emitting state and non-light emitting state, dimming operation, changing the direction of the light emitting surface) as necessary based on this setting information. (Or maintenance of the light emitting surface orientation) is automatically executed.

  Thus, according to the structure which can adjust several illuminating devices all at once, the space of the refined impression can be implement | achieved easily (or reproduced). That is, it becomes possible to easily shift the light space irradiated with light from various illumination devices such as indoors to a state where it can be most beautifully seen.

  In the above-described embodiment, an example in which an organic EL panel is adopted as the light-emitting panel 15 has been described, but the present invention is not limited to this. As the light-emitting panel, a surface light-emitting panel such as an LED panel in which LEDs are arranged in a plane or an LED panel in which an LED and a diffusion plate are combined may be employed. In the above-described embodiment, a flat panel is adopted as the light emitting panel, but a curved panel may be used.

  In the above-described embodiment, the example in which the lighting device is attached to the side wall surface (attachment surface 6) of the indoor space has been described, but the lighting device may be attached to the ceiling surface or the floor surface instead of the side wall surface. However, as described above, it is preferable to attach to the side wall surface of the indoor space in order to form a sophisticated impression space.
