  Hereinafter, the lighting fixture 10 of this embodiment is demonstrated using FIG. 1 thru | or FIG. 5, and the surface emitting module 1 used for the lighting fixture 10 is demonstrated using FIG. 6 and FIG. In FIG. 1, in order to make the structure of the luminaire 10 easy to understand, the structure is partially broken.

  As shown in FIG. 1, the lighting fixture 10 of the present embodiment includes a mounting portion 4 that is attached to the ceiling side of a structure, a suspension member 5 that is held by the attachment portion 4 at one end 5a side, and the other end 5b of the suspension member 5 An instrument body 6 that holds the side and is suspended by the suspension member 5 is provided. The instrument body 6 has a flat frame portion 7a having an opening hole 7aa in the center portion and at least a pair of extended portions 7b extending from the periphery of the frame portion 7a and facing each other via the frame portion 7a in plan view. The body body 7 is provided (see FIG. 2). Moreover, the instrument main body 6 has the cover body 8 which covers the planar surface emitting module 1 provided in each of the extending part 7b. Here, in the body body 7, a through hole 7 ba that radiates light from the light emitting surface 1 aa of the surface emitting module 1 is provided in each of the extending portions 7 b. In addition, the body 7 has an extending portion 7b inclined with respect to the frame portion 7a in a direction in which the back surface 1ab side of the surface emitting module 1 opposite to the light emitting surface 1aa approaches each other. Furthermore, the cover body 8 holds the other end 5b side of the suspending member 5 inclined with the virtual perpendicular line V of the flat frame portion 7a and is substantially parallel to the extending portion 7b along the back surface 1ab side of the surface emitting module 1. It extends to the frame part 7a side. The virtual perpendicular V is provided perpendicular to a plane parallel to the main surface of the flat frame portion 7a.

  Thereby, the lighting fixture 10 of this embodiment can make a viewer recognize the thickness reduction of the whole fixture more.

  By the way, the applicant has made use of the feature that the surface-emitting module 1 can be made thin and light, and as shown in FIG. 8, the entire lighting fixture has been made thinner as compared with incandescent bulbs and fluorescent lamps. A lighting fixture 11 was constructed. In addition, in FIG. 8, in order to make the structure of the lighting fixture 11 easy to understand, it is partially broken and illustrated.

  The luminaire 11 includes a mounting portion 4 that is attached to the ceiling side of the structure, a suspension member 5 that is held on one end 5a side by a holding fitting 9c of the attachment portion 4, and a suspension member 5 that holds the other end 5b side of the suspension member 5 It has the instrument main body 6 suspended by. The instrument body 6 has a flat frame portion 7a having an opening hole 7aa in the center portion and at least a pair of extended portions 7b extending from the periphery of the frame portion 7a and facing each other via the frame portion 7a in plan view. A body body 7 is provided. Moreover, the instrument main body 6 has the cover body 8 which covers the planar surface emitting module 1 provided in each of the extending part 7b. Here, in the body body 7, a through hole 7 ba that radiates light from the light emitting surface 1 aa of the surface emitting module 1 is provided in each of the extending portions 7 b. In addition, the body 7 has an extending portion 7b inclined with respect to the frame portion 7a in a direction in which the back surface 1ab side of the surface emitting module 1 opposite to the light emitting surface 1aa approaches each other. The cover body 8 holds the other end 5b side of the suspension member 5 parallel to the virtual perpendicular V of the flat frame portion 7a. Since the cover body 8 accommodates and covers the mounting bracket 9d for holding and attaching the other end 5b side of the suspension member 5 parallel to the virtual perpendicular V on the frame part 7a side of the cover body 8, it is substantially parallel to the frame part 7a. It extends to the position facing the frame portion 7a. Thereby, the cover body 8 can hold the body body 7 without applying a bending load to the one end 5 a and the other end 5 b of the suspension member 5.

  The luminaire 11 shown in FIG. 8 has an opening hole 7aa penetrating through the central portion of the frame portion 7a. Therefore, in the lighting fixture 11, when the viewer visually recognizes the fixture main body 6 from the floor surface side, the back surface 1ab side of the surface emitting module 1 can be visually recognized through the opening hole 7aa. The lighting fixture 11 can emphasize the thin surface emitting module 1 through the opening 7aa compared to an incandescent bulb or a fluorescent lamp. Compared with the conventional lighting fixture 100 shown in FIG. 9, the lighting fixture 11 can make the viewer recognize the thinning of the entire lighting fixture 11.

  However, in the lighting fixture 11, the mounting bracket 9d on the other end 5b side of the suspension member 5 is disposed on the periphery of the frame portion 7a, and the thickness of the cover body 8 that covers the mounting bracket 9d by the amount of the mounting bracket 9d is the surface emitting module. It tends to be thicker than the thickness of 1. When the viewer visually recognizes the fixture main body 6 obliquely upward from the floor surface side, the lighting fixture 11 may visually recognize the end surface 8d of the cover body 8 that covers the mounting bracket 9d through the opening hole 7aa. In particular, when the fixture body 6 is suspended from the attachment portion 4 side by the suspension member 5 parallel to the virtual perpendicular V of the frame portion 7a, the illumination fixture 11 has a thickness of the cover body 8 to cover the attachment fitting 9d. It must be thicker than the thickness of the light emitting module 1. Therefore, in the lighting fixture 11, depending on the angle at which the viewer visually recognizes the fixture body 6, the thin surface emitting module 1 cannot be emphasized through the opening 7aa, and the viewer recognizes the thinning of the entire lighting fixture 11. It may be difficult to let them.

  In the lighting fixture 10 of this embodiment, the cover body 8 extends to the frame portion 7a side substantially parallel to the extending portion 7b along the back surface 1ab side of the surface emitting module 1. Therefore, in the lighting fixture 10, when a viewer visually recognizes the back surface 1ab side of the surface emitting module 1 through the opening hole 7aa, the thin surface emitting module 1 can be emphasized regardless of the angle at which the fixture body 6 is viewed. It becomes possible to make a viewer recognize the thinning of the entire instrument 10.

  Moreover, the lighting fixture 10 of this embodiment comprises an inclined surface in which the cover body 8 side and the body body 7 side are continuous in the vicinity of the opening hole 7aa in a state where the body body 7 and the cover body 8 are fitted. Designed to do. In other words, the cover body 8 is in contact with the frame portion 7a at an angle inclined on the body body 7 side. In the lighting fixture 10 of this embodiment, since the cover body 8 side and the body body 7 side constitute an inclined surface, there is no risk of damaging the aesthetic appearance of the design that is visible from the outside through the opening hole 7aa, and as a design It is also possible to improve the appearance.

  Furthermore, in the lighting fixture 10 of the present embodiment, the cover body 8 extends to the frame portion 7a side substantially in parallel with the extending portion 7b along the back surface 1ab side of the surface emitting module 1, so that surface emission is performed through the opening hole 7aa. It is easy to generate an air flow along the cover body 8 on the back surface 1ab side of the module 1. Therefore, in the lighting fixture 10 of this embodiment, the back surface 1ab side of the surface light emitting module 1 can be cooled more uniformly, and the surface light emitting module 1 can contribute to the uniformity of surface light emission.

Moreover, the extending part 7b may provide the translucent panel (not shown) so that the through-hole 7ba may be block | closed, and does not need to provide. The translucent panel can be formed of, for example, a translucent material (for example, silicone resin, acrylic resin, glass, etc.). The luminaire 10 may radiate light from the surface light emitting module 1 to the outside through a translucent panel. The translucent panel may have a flat plate shape or a lens shape for condensing or diffusing light from the surface light emitting module 1. In addition, the body body 7 can appropriately use, for example, a resin material such as an ABS resin or a metal material (for example, stainless steel or aluminum) having better thermal conductivity than the resin material as the material of the body body 7. .

  The cover body 8 is formed in a box shape having an opening on the body body 7 side, and has a flat portion 8a that covers the back surface 1ab side of the surface emitting module 1 and a side wall 8b that stands from the outer periphery of the flat portion 8a. doing. As for the cover body 8, the flat part 8a and the side wall 8b are integrally formed. The side wall 8 b is formed so that the inner peripheral surface of the side wall 8 b surrounds the peripheral wall portion 7 c that matches the outer periphery of the surface emitting module 1. The cover body 8 can easily position the surface emitting module 1 only by covering the peripheral wall portion 7c. In the cover body 8, a side wall 8 b of the cover body 8 and a peripheral wall portion 7 c erected from the extending portion 7 b of the body body 7 are fixed by a plurality of screw portions 82. In addition, the cover body 8 can appropriately use, for example, a resin material such as an ABS resin or a metal material (for example, stainless steel or aluminum) having better thermal conductivity than the resin material as the material of the cover body 8. .

  The cover body 8 fixes the base portion 3 of the surface emitting module 1 to the flat portion 8a side of the cover body 8 with screws or the like (not shown). In the lighting fixture 10 of this embodiment, the surface emitting module 1 can be accommodated between the body body 7 and the cover body 8 with the surface emitting module 1 mounted on the cover body 8 side. In the cover body 8, the side wall 8 b of the cover body 8 is screwed to the peripheral wall portion 7 c of the extending portion 7 b of the body body 7 by the screw portion 82.

  Since the lighting fixture 10 is designed so that the peripheral wall portion 7c can come into contact with the inner peripheral surface of the side wall 8b of the cover body 8, the surface emitting module 1 in which the base portion 3 is fixed to the cover body 8 side, Positioning can be performed simply by fitting on the body 7 side. Therefore, the lighting fixture 10 can make assembly work efficient. In the lighting fixture 10 of the present embodiment, the cover body 8 does not have the side wall 8b on the frame portion 7a side of the cover body 8. For this reason, the cover body 8 can slide the light emitting section 2 with respect to the base section 3 when the light emitting section 2 is attached to and detached from the base section 3 fixed to the cover body 8. The lighting fixture 10 of this embodiment can remove the light emission part 2 from the base part 3 fixed to the cover body 8 comparatively easily, and can also perform the replacement | exchange work of the light emission part 2 of the surface emitting module 1 easily.

  In addition, the lighting fixture 10 should just be able to arrange | position the surface emitting module 1 between the body body 7 and the cover body 8, for example, and the space of the space between the body body 7 and the cover body 8 rather than the thickness of the surface emitting module 1 is sufficient. What is necessary is just to set a magnitude | size slightly large. The lighting fixture 10 emphasizes that the thickness of the surface light emitting module 1 is thin, so that the size of the space between the body body 7 and the cover body 8 is preferably as small as possible. A spacer or the like for filling the gap with the surface emitting module 1 may be provided. The lighting fixture 10 can have any shape corresponding to the use of the lighting fixture 10 and the shape of the surface emitting module 1 in the shape of the cover body 8 and the body body 7 constituting the fixture body 6.
