Next, the attachment member 40 for attaching the light emitting module 14 to the lattice-like sheet member 12 will be described with reference to FIGS.
The attachment member 40 is a metal member having a sandwiching portion 42 that sandwiches the light emitting module 14 and an attachment portion 44 for attaching the light emitting module 14 to the intersecting portion 22 of the lattice-like sheet member 12.
Such an attachment member 40 is formed by processing a steel plate having a thickness of about 0.5 mm by pressing or the like.

The holding portion 42 of the mounting member 40 includes a substrate portion 46 and two standing pieces 48 a and 48 b that stand vertically from both ends of the substrate portion 46 with respect to the surface of the substrate portion 46. The standing piece 48a and the standing piece 48b are provided with substantially rectangular engagement openings 50a and 50b, respectively.
When the light emitting module 14 is sandwiched between the sandwiching portions 42, the engaging convex portions 32 formed on the side surfaces of the module case 24 are inserted into the engaging openings 50a and 50b of the standing pieces 48a and 48b and engaged. For this reason, unless the upright pieces 48a and 48b are deformed in the direction in which they extend, the light emitting module 14 is not detached from the mounting member 40, and the mounting member 40 can reliably hold the light emitting module 14.

  Further, an orthogonal substrate portion 52 extending in a direction orthogonal to the extending direction of the substrate portion 46 is formed at an end portion on either one side of the substrate portion 46. The surface of the orthogonal substrate portion 52 and the surface of the substrate portion 46 are formed in the same plane, and the surfaces of the substrate portion 46 and the orthogonal substrate portion 52 are in contact with the bottom surface of the light emitting module 14 (the bottom surface of the power supply coated cable 16). It becomes a part.

Two holding pieces 54a and 54b are provided at a predetermined interval on the surface opposite to the side on which the standing pieces 48a and 48b stand up on the substrate portion 46 (the back surface of the substrate portion 46).
The holding pieces 54 a and 54 b are provided so as to extend from both ends of the orthogonal substrate portion 52 in the same direction as the extending direction of the substrate portion 46, and are cantilevered at a portion connected to the orthogonal substrate portion 52. Yes.

  Each of the holding pieces 54 a and 54 b includes a base portion 56 that extends from the orthogonal substrate portion 52 by a predetermined distance in the back surface direction, and a holding portion 58 that extends in the same direction as the extending direction of the substrate portion 46, which is a direction orthogonal to the base portion 56. A front end portion 60 bent in the direction of the substrate portion 46 from the front end of the holding portion 58, and an introduction inclined portion 62 formed so as to be gradually inclined in a direction away from the substrate portion 46 at the front end of the front end portion 60. Have.

The holding portions 58 of the holding pieces 54 a and 54 b are arranged with a predetermined distance A between the holding pieces 54 a and 54 b and the substrate portion 46. The interval A is determined by the length of the base portion 56 and is formed to have substantially the same length as the thickness of the vertical sheet portion 18 or the horizontal sheet portion 19.
In other words, the holding recesses for receiving and holding the vertical sheet portion 18 or the horizontal sheet portion 19 are recessed by the base portion 56, the holding portion 58, and the tip portion 60 of the holding pieces 54 a and 54 b in a direction in which the holding portion 58 is separated from the substrate portion 46. Form. When the vertical sheet portion 18 or the horizontal sheet portion 19 is stored in the storage recess, the base portion 56 that is the inner wall surface of the storage recess and the front end portion 60 abut on the side surface of the vertical sheet portion 18 or the horizontal sheet portion 19. Abutting as a surface, the vertical sheet portion 18 or the horizontal sheet portion 19 is held.

  Further, the holding pieces 54a and 54b are arranged with a predetermined interval B therebetween. The interval B is formed to be approximately the same length as the width of the vertical sheet portion 18 or the horizontal sheet portion 19 or slightly longer. In other words, either the vertical sheet portion 18 or the horizontal sheet portion 19 of the lattice-shaped sheet member 12 is disposed between them.

Then, the state which attached the attachment member 40 to the grid | lattice-like sheet member 12 is shown in FIGS.
Here, since the vertical sheet portion 18 is held by the holding pieces 54a and 54b, the longitudinal direction of the vertical sheet portion 18 is a direction orthogonal to the extending direction of the holding pieces 54a and 54b, and the horizontal sheet portion 19 is the holding piece. The mounting member 40 is disposed with respect to the lattice-shaped sheet member 12 so as to be disposed in the gap between the 54a and the holding piece 54b.

  When the vertical sheet portion 18 is to enter the holding portion 58 from the introduction inclined portion 62 of the holding pieces 54a and 54b, the holding pieces 54a and 54b open on the introduction inclined portion 62 side due to the spring property of the base portion 56 portion, and the vertical sheet. The portion 18 enters between the holding pieces 54a and 54b and the substrate portion 46 and is held immovably by being housed in the housing recess.

Moreover, the horizontal sheet | seat part 19 is arrange | positioned between holding pieces 54a and 54b.
The width of the horizontal sheet portion 19 is formed to be slightly shorter than the interval between the holding pieces 54a and 54b. However, even if the lattice sheet member 12 is moved in the horizontal direction, both side surfaces of the horizontal sheet portion 19 are held. Since they abut against the opposing side surfaces of the pieces 54a, 54b, they are provided so as not to move in the width direction of the lateral sheet portion 19.

Further, as shown in FIG. 21, the mounting direction of the mounting member 40 may be configured such that the opening sides of the holding pieces 54 a and 54 b are staggered with respect to one light emitting module unit.
That is, the opening sides of the holding pieces 54a and 54b of the mounting member 40 are staggered, so that when the mounting member 40 is mounted on the lattice-shaped sheet member 12, the mounting directions are different one by one. For this reason, even when a force is applied to the entire light emitting module unit from one direction, it is possible to prevent the entire light emitting module unit from being detached because the removal directions are alternate.

Unlike the above-described embodiment, the present embodiment is different in that the power supply covered cable 16 is disposed along the lateral sheet portion 19 of the lattice-shaped sheet member 12. Therefore, the mounting direction of the mounting member 40 is also set so that the opening side of the holding pieces 54a and 54b faces downward or upward, and the vertical sheet portion 18 is disposed between the holding pieces 54a and 54b. Like that.

The light emitting module array display device 10 of the present embodiment can also be fixed by fixing the uppermost horizontal sheet portion 19a to a wall, a column, a beam or the like.

(Fifth embodiment)
In each embodiment mentioned above, the attachment member 40 of the light emitting module concerning this invention was demonstrated on the assumption that it attaches to a grid | lattice-like sheet member. However, even when the grid-like sheet member 12 is not used, it may be necessary to fix the light emitting module unit 21 at any location.
Each holding portion 58 of the holding pieces 54a and 54b is formed with an insertion hole 64 for inserting a screw when screwing or the like is performed.

For example, as shown in FIG. 25, when it is desired to fix the attachment member 40 to the wall surface 98 or the like, the screw 96 is inserted into the insertion hole 64 so that the screw head 97 is disposed between the holding portion 58 and the substrate portion 46. The mounting member 40 can be fixed to the wall surface 98 or the like by inserting the screw 96.
Here, as shown in the figure, the screw head 97 is sized so that it can be stored in the storage recesses (between the holding portion 58 and the substrate portion 46) of the holding pieces 54a and 54b. The light emitting module 14 can be securely attached to the mounting member 40 without interference.

  Needless to say, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

  For example, in each of the above-described embodiments, the light emitting module array display device including a total of 16 light emitting modules of 4 vertical × 4 horizontal has been described, but M × 1, 1 × N, M × It goes without saying that the case of N (M and N are natural numbers) is also included.
