As shown in FIG. 1, the LED M sign board according to the present invention includes a base 10, a frame 20, a facade module 30, a controller 50, and a gap adjusting unit 40.

The frame 10 is fixed to the outer wall of the building and supports the frame 20 installed forward of the frame.

The frame 20 is installed in front of the mount 10, the facade module 30 is installed in front of the frame 20, and the controller 50 is installed in the rear.

The facade module 30 implements and displays an image with light.

The facade module 30 includes an LED board 31, a diffusion plate 35, a screen film 37, and a protective cover 39.

The LED board 31 includes an LED 32 and a board 33 on which the LEDs 32 are mounted and is mounted in front of the frame 20. The LED 32 preferably uses a full color LED to emit light of various colors.

In the figure, the LED board 31 is shown in a rectangular shape. When the LED boards of the BAR type are used, the overall shape of the facade module 30 may be a pentagon, Hexagonal, circular, and other shapes. Also, during maintenance, only the LED board on which the faulty LED is mounted can be replaced, which is economical.

The diffusion plate 35 is disposed in front of the LED board 31 to diffuse the incident light and irradiate the screen film 37 on the front side.

The light emitted by the LEDs 32 is spaced a certain distance away from the LEDs 32 to form a lattice shape. In this case, the light emitted from the LEDs 32 is not smoothly connected to the outline of the image. So that the outline of the image is smoothly connected. That is, the image is displayed more naturally and displayed.

The screen film 37 is disposed in front of the diffusion plate 35, and images of light incident on the diffusion plate 35 are transferred and displayed.

The protective cover 39 is disposed in front of the screen film 37 to protect the screen film 37, the LED board 31, and the like.

The controller 50 controls the LED board 31 to implement an image. That is, the LEDs 32 of the LED board 31 are turned on and the color of light is controlled.

The controller 50 includes a memory for storing image data related to an image to be implemented by the LED board 31 and a controller for mapping the image data and the LEDs 32 based on the arrangement information of the LEDs 32 arranged in a lattice form And a driver for turning off the LEDs 32 based on the mapping information of the mapping unit. It may be desirable for the memory to be able to easily change the image to be displayed on the LED board 31 using a replaceable SD card.

The gap adjusting means 40 adjusts the distance between the mount 10 and the frame 20. The gap adjusting means 40 are provided at four corners of the frame 10 and the frame 20 to adjust the direction of the frame 20, respectively.

The gap adjusting means 40 adjusts the interval between the frame 10 and the frame 20 to facilitate the operation of replacement and maintenance of the controller 50 and the facade module 30, So as to make the image of the LED board 31 more visible to the surrounding passers-by.

3 to 5, the gap adjusting unit 40 includes an upper plate 41, a lower plate 42, a rotating disk 43, a forward / backward rod 44, a lifting pin 45, An elevating / lowering block 47, an operation lever 48, and a cover 49.

The upper plate 41 is coupled to the lower portion of the frame 20 and the lower plate 42 is coupled to the upper portion of the frame 10.

A shaft 421 protrudes upward from the center of the lower plate 42 and a take-out inlet 411 inserted into the shaft 421 is provided at the center of the upper plate 41.

A shaft hole 431 formed at the center of the rotary disk 43 is inserted into the shaft 421 and rotatably disposed on the upper surface of the lower disk 42.

A plurality of guide grooves 433 are formed in the rotation disc 43 so as to be inwardly directed from the outer side to the inner side without being directed toward the center of the inner side.

At the edge of the rotary disk 43, a saw tooth 435 is formed at a predetermined interval.

The guide block 46 is mounted on the lower plate 42 so as to be disposed around the rotary disk 43.

The forward / backward rod (44) is coupled to the guide block (46) such that it can move back and forth.

A forward / backward roller (441) protrudes downward from the forward / backward rod (44). The forward and backward rollers 441 are disposed inside the guide groove 433 of the rotary disk 43.

The upward / downward pin 45 protrudes upward from the rear of the forward / backward rod 44.

A lifting / lowering roller 451 is provided at the upper end of the lifting / lowering pin 45.

The ascending / descending block 47 protrudes from the lower surface of the upper plate 41.

The ascending / descending block 47 is provided with an inclined surface 471 inclined from the outside to the inside. The ascending / descending roller 451 is brought into contact with the inclined surface 471. An elevation groove 473 on which the elevating roller 451 is placed is formed on the inclined surface 471.

The operation lever 48 is operated by a user to rotate the rotary disk 43.

A gear 485 engaging with a tooth 435 provided on the rotary disk 43 is formed on the front of the operation lever 48 and a handle 481 is formed on the rear side to grasp and rotate by the user.

The cover (49) covers the lower plate (42). A through hole 491 through which the shaft 421 penetrates is formed in the center of the cover 49 and an exposing hole 491 is formed in the periphery of the through hole 491 so that the up / 493 are formed.

The process of adjusting the height of the main body 10, that is, the interval between the upper plate 41 and the lower plate 42, through the gap adjusting means 40 having the above-described structure will be described below.

First, when the user holds the handle 481 of the operation lever 48 and rotates in one direction, the gear 485 and the tooth 435 engage with each other to rotate the rotary disk 43.

When the rotary disk 43 rotates, the inner wall of the guide groove 433 pulls or pushes the forward / backward roller 441 in accordance with the rotation direction so that the forward / backward roller 441 moves along the guide groove 433 .

When the forward / backward roller 441 moves along the guide groove 433, the forward / backward rod 44 moves together to move forward or backward, and the upward / downward pin 45 moves forward or backward together.

When the ascending / descending pin 45 is moved forward or backward, the ascending / descending roller 451 moves on the inclined surface 471 of the ascending / descending block 47 to push up the upper plate 41, So that the distance between the upper plate 41 and the lower plate 42 is adjusted.

The gap between the base 10 and the frame 20 can be easily adjusted by simply holding the handle 481 of the operation lever 48 by the user, The lowering roller 451 moves in contact with the inner wall of the guide groove 433 and the inclined surface 471 of the ascending / descending block 47 to reduce noise caused by contact with the load due to the movement, The forward and backward movements of the forward and backward rods 44 are synchronized with each other and travel the same distance, so that the entire upper plate 41 is lifted up and down in a uniform distance without being tilted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Should be interpreted as falling within the scope of protection.
