3 and 4, the LED module 200 is mounted on the case 300, the LED board 400 mounted on the front of the case 300, and the front of the LED board 400. It consists of a blocking plate 500.

The case 300 has a step 311 in the rear direction formed on the inner side of the edge 310 at the front of the quadrilateral edge 310 so that the inside of the edge 310 in the rear direction based on the step 311. The board seating surface 320 is made to enter to form a body. Here, the inner surface surrounded by the board seating surface 320 to penetrate in the front and rear direction, so that the board seating surface 320 has a stepped surface of the quadrilateral shape along the edge 310, the board formed as described above The seating surface 320 is fixed to the screw fastening by mounting the rim of the LED board 400 to be described later. For screwing, the board seating surface 320 was formed with a plurality of front-side female screws 360, in the embodiment of the present invention by projecting the board seating surface 320 in the form of a protrusion 321, The front side female screw 360 of the front of the protrusion 321 was formed.

In addition, the inside of the board seating surface 320 is formed in parallel with the two reinforcing pieces 330 connecting the upper inner surface and the lower inner surface, and also forming a connecting piece 331 connecting the two reinforcing pieces 300 to each other. It was. In this case, the thickness of the reinforcing piece 330 and the connecting piece 331 is smaller than the thickness between the board seating surface 320 and the rear surface to have a stepped portion in the portion subsequent to the board seating surface 320. By forming the reinforcing piece 330 and the connecting piece 331 in such a thickness, even if a circuit element (not shown) for controlling the lighting of the LED 410 is mounted on the back of the LED board 400 is not caught.

On the other hand, since the LED board 400 to be described later is formed in the form of a thin circuit board, in order to prevent the central portion from being bent when seated on the board seating surface 320, the projection of the front side of the connecting piece 331 The threaded protrusion 332 is formed, and the front side female screw 360 is further formed on the front of the threaded protrusion 332.

On the back of the case 300, the groove 350 is formed along the edge and the sealing ring 351 is inserted into the groove 350 to protrude.

In addition, by forming a locking projection 340 on the upper end side of the case 300, by drilling the locking groove 160 on the upper surface of the grating plate 100 corresponding to the position of the locking projection 340, The locking protrusion 340 may be inserted into the locking groove 160.

In addition, a plurality of rear side female screws 370 are formed on the rear surface of the case 300. In the embodiment of the present invention, the rear surface of the protrusion 321 is formed on four corners of the plurality of protrusions 321. Side female screws 370 were respectively formed.

At this time, the rear side female screw 370 is formed on the same line as the front side female screw 360 formed in the front of the corresponding position to communicate with each other. In addition, the cross-sectional center of the rear side female screw 370 coincides with the cross-sectional center of the front-side female screw 360.

Here, the rear female screw 370 is screwed into the rear male screw 371 through which the panel 20 and the lattice plate 100 penetrate 24 and 150 from the rear side, and the case 300 is connected to the lattice plate ( 100, and the rear side female screw 370 is for mounting the case 300, so that its diameter is larger than the front female screw 360 for mounting the LED board 400.

The case 300, the LED board 400 to be described later to be mounted flat, and the contact surface with the grid plate 100 should also be flat, so that it is preferably produced by die casting (die casting) not bent.

The LED board 400, the rear surface of the rim portion is fitted in a surface contact with the board seating surface 320 of the case 300, a plurality of LEDs 410 is mounted on the front, of the LED 410 Circuit elements for controlling lighting and supplying electricity are mounted on the rear surface according to the circuit pattern.

In addition, the LED board 400, the through hole 420 is formed to match the position of the front-side female screw 360 of the case 300. Here, the LED display board is mounted in a plurality of LEDs 410 densely and vertically at the front and rear of the LED board 400 in order to output not only a variety of letters, but also the design, the arrangement position of the through hole 420 also LED The circuit pattern of the board 400 is considered beforehand when designing a circuit. When the LED board 400 is inserted into the board seating surface 320, the through hole 420 and the front side female screw 360 of the case 300 are positioned at the same position.

The blocking plate 500 is disposed at the front in a state in which the LED board 400 is inserted into the board seating surface 320 of the case 300, and the blocking plate 500 and the LED board 400 are removed from the front side. The front-side male screw 361 which penetrated 520 and 420 is fastened to the front-side female screw 360 formed in the board seating surface 320, and is fixed.

In addition, a light guide hole 510 is formed at each of the LEDs 410 mounted on the front surface of the LED board 400 in the blocking plate 500. In this case, the light guide hole 510 is a through hole that allows the LED 410 to be seen from the front direction, and is widened toward the front direction, and makes the upper surface 511 of the interior horizontal in the front and rear directions. That is, the inner top surface of the light guide hole 510 forms a horizontal plane, and both sides and the bottom surface gradually increase in size of the holes in the front portions 512 and 513. That is, since the upper surface is a horizontal plane, external light such as sunlight is blocked from being incident in the direction of the LED 410, so that the light emitted from the LED 410 is good to enter the human view. The light guide hole 510 having such a structure has a form of a groove formed in a plate shape, and thus has an advantage of being easier to manufacture than a shade of shade of a conventional shade.

As such, when mounting the LED module 200 including the LED board 400, the blocking plate 500, and the case 300 to the grating plate 100, first, the locking protrusion 340 is attached to the grating plate 100. Since it is inserted into the locking groove 160, the mounting position of the case 300 can be easily selected, and accordingly, the rear side male screw 371 can be easily fastened to mount the case 300.

In addition, since the sealing ring 351 inserted to protrude in the rear direction is in contact with the front surface of the grating plate 100 at the rear surface of the case 300, the locking protrusion 340 is inserted into the locking groove 160. When the case 300 is pressed from the front side, the case 300 does not move on the grid 100. As a result, the rear male screw 371 can be tightened more easily.

In addition, the sealing ring 351 may prevent foreign matter, in particular, water from penetrating into the case 300. In order to completely prevent the infiltration of foreign matter, it is preferable that the rear side female screw 370 is formed inside the groove 350.

In addition, the case 300 is also part of the case 300 for forming the female screw (360, 370) by arranging the front side female screw 360 and the rear side female screw 370 on the same line and in communication with each other in the case 300 It can be minimized.

The board seating surface 320 of the case 300 should be close to the board seating surface of the neighboring case and the proximity distance should be short enough to make the intervals of the LEDs 410 uniform at equal intervals over the entire display board. Accordingly, the LED board 400 should be designed to mount the LED 410 at the position of the board seating surface 320. In addition, the back surface of the LED board 400 should be formed to have a narrow width as possible to the board seating surface 320 in order to be cooled by the air, and the sealing ring 351 has a useful function as described above ), The space where the front side female screw 360 and the back side female screw 370 are formed also becomes narrow. Therefore, in the present invention, the front side female screw 360 is also formed at the front of the position at which the rear side female screw 370 is formed, so that the parts for forming the female screws 370 and 360 are minimized.

In addition, the front female screw 360 and the rear female screw 370 communicate with each other, and the front female screw 360 is formed smaller than the rear female screw 370, so that the front female screw 370 is first formed, and then the front female screw 370 is formed. By forming the female screw 360, it is possible to clean the parts communicating with each other. That is, when the cross-sectional center of the front female screw 360 is out of the cross-sectional center of the rear female screw 370, the end of the front female screw 360 having a small diameter may damage the thread of the rear female screw 370. Because there is. In order to prevent this, the case 300 may be made thick, but the thickness of the case 300 is preferably thin enough to satisfy only the required depths of the female screws 360 and 370. In order to easily form the female screws 360 and 370 while being small, they are arranged on the same line and are in communication with each other.

In addition, since the LED board 400 is fitted to the module seating surface 320 of the case 300 and is located inside the edge 310 and covered by the blocking plate 500, the LED board 400 is not exposed to the outside. Therefore, the LED board 400 is not damaged when carrying or installing the LED module 200 configured as described above.

In addition, in the present invention, the grid plate 100 is used to firmly fix the LED module 200 configured as described above to the panel 20. Since the grating plate 100 is configured in the form of a plate having a plurality of through holes 130, since the multiple sheets can be stored and transported at the time of being separated and stored in the panel 20, it is easy to handle and is flat without bending. Can be maintained. On the other hand, conventionally, there is a problem that the panel is formed integrally with the panel or is not flat, but has a curved shape when transporting or installing, and thus it is difficult to achieve a vertical plane even when the LED module is mounted. However, the present invention solves this problem and has the advantage of convenience of transportation and storage.

Although illustrated and described in the specific embodiments to illustrate the technical spirit of the present invention, the present invention is not limited to the same configuration and operation as the specific embodiment as described above, within the limits that various modifications do not depart from the scope of the invention It can be carried out in. Therefore, such modifications should also be regarded as belonging to the scope of the present invention, and the scope of the present invention should be determined by the claims below.
