The bolt is assembled to prevent the inflow of foreign substances and water into the receiving groove 115.

On the other hand, the LED module 150 is coupled to the front of the frame 110.

The LED module 150 includes a seating plate 160 that forms a seating groove 162 so that the LED board 155 on which the plurality of LEDs 157 are arranged is seated, and each of the LEDs 157 of the LED board 155. An opening hole 177 is formed to cover the transparent waterproof cap 170 and the transparent waterproof cap 170 to the front surface, and the fixing cap 175 and the fixing cap 175 covering the front surface of the seating groove 162. ) Includes a locking unit 180 that is fixed so as not to be separated from the seating groove 162.

The seating groove 162 of the seating plate 160 is formed in a plurality of rows spaced apart from each other, and the inner surface of the seating recess 162 is formed with a step 164 to allow the edge of the LED board 155 to be spaced apart from the rear surface. do.

The upper and lower surfaces of the seating recess 162 are bent inwardly to form the step 164, so that upper and lower edges of the LED board 155 are seated so that the heat generated from the LED 155 is directly applied to the seating plate 160. It is to prevent delivery.

The seating groove 162 of the seating plate 160 has a structure in which a plurality of rows are spaced apart from each other, so that the seating grooves 162 are opened and ventilated with the front and rear sides, and made of aluminum.

And, on the rear of the seating groove 162, the heat radiation jaw 166 is formed in each of the upper and lower portions by a cutting process.

In addition, the connector 168 is formed at the center of the mounting groove 162 so that the connector 132 of the distribution board 130 is electrically connected to the LED board 155.

The transparent waterproof cap 170 has a rectangular parallelepiped shape in which one side is opened to cover the entire LED 157 of the LED board 155, and each of the transparent waterproof caps 170 is connected to each other by a connecting piece 172.

And, since the transparent waterproof cap 170 is a transparent body made of a soft synthetic resin end is in close contact with the front of the LED board 155 to the LED 157 is waterproof, and to accurately transmit the light of the LED 157 to the front desirable.

And the fixing cap 175 is fixed to the seating plate 160 by the locking unit 180 to prevent the transparent waterproof cap 170 is separated.

The locking unit 180 includes a locking jaw 182 protruding from the inner surface of the seating groove 162 and a fixing hook 184 protruding from the lower surface of the fixing cap 175 to be caught by the locking jaw 182.

At this time, it is preferable that the coating layer 185 is formed by filling a silicon or epoxy material in the fixed cap 175 fixed by the locking unit 180.

An opening hole 192 is formed on the front surface of the mounting plate 160 so that the LED 157 of the LED board 155 is exposed, and the sunshade film 195 is formed on the upper and lower portions of the opening hole 192 to block external lighting. The shading member 190 is further provided.

A fastening hook 197 is formed on the rear surface of the sunshade member 190 so as to be caught and fixed to an outer surface of the seating groove 162.

This is because the upper and lower surfaces of the seating groove 162 is bent to form the step 164 inside the seating groove 162, the fastening hook 197 of the sunshade member 190 is bent on the outer surface of the seating groove 162. Can be fixed by hanging on the site.

Hereinafter, the operation and effects of the LED module and the LED display board having the same according to an embodiment of the present invention will be described.

First, the distribution substrate 130 is seated in the receiving groove 115 of the frame 110. Then, the rigid plate 135 made of aluminum is seated on the front surface of the distribution board 130, and the gasket 140 is coupled to the front surface thereof to cover the receiving groove 115.

Exposed holes 135a and 140a are formed in the rigid plate 135 and the gasket 140 to expose the connector 132 of the distribution board 130 to the front.

By combining the gasket 140 to prevent the inflow of foreign substances and water into the receiving groove 115, the distribution board 130 is waterproof, and the distribution board 130 is protected from the external shock by the rigid plate 135.

Then, the mounting plate 160 is bolted to the front of the frame 110. Then, the connector 132 of the distribution board 130 is exposed to the front side through the connector 168 of the mounting groove 162.

Then, as the LED board 155 is seated in the seating groove 162, the connector 132 is electrically connected to transfer an external signal to the LED board 155.

In addition, the upper and lower surfaces of the seating recess 162 are bent to form a step 164 on the inner surface thereof so that only the edge of the LED board 155 is seated, thereby improving the heat dissipation effect of the LED 157.

In addition, the rear surface of the seating groove 162 is formed by the heat radiation step 166 by a cutting process to increase the contact area with air and thin to double the heat radiation effect.

Next, the transparent waterproof cap 170 is coupled to the LED 157 of the LED board 155 to be waterproof. The transparent waterproof cap 170 is connected to each other by the connecting piece 172, it is easy to combine by maintaining the clearance by the interval of the LED 157.

Thereafter, the fixing cap 175 on the front surface is coupled to the seating groove 162 by the locking unit 180 to prevent the LED board 155 and the transparent waterproof cap 170 from being separated.

The fixing hook 184 protruding toward the rear side of the fixing cap 175 is coupled to the locking jaw 182 of the seating recess 162 to be fixed.

At this time, the fixing cap 175 is filled with a silicon or epoxy material to form a coating layer 185 to be completely waterproof.

When the shading member 190 is coupled to the front surface of the seating plate 160 in the above state, the assembly is completed.

The assembly of the sunshade member 190 is fixed to the hook hook 197 formed to protrude to the rear side is caught by the outer surface bending portion of the seating groove 162.

The sunshade member 190 has a sunshade film 195 formed on the upper and lower portions of the opening hole 192 to effectively block sunlight or external lighting to maximize the contrast ratio of the LED 157.

As such, the data cable is connected to the distribution board 130 through the connector 116 of the receiving groove 115 in the state where the assembly is completed, and is transferred to the LED board 155 through the connector 132 of the distribution board 130. To implement the image.

At this time, the back of the connector 116 is provided with a waterproof cover 120 to waterproof the interior of the receiving groove 115.

Meanwhile, as illustrated in FIG. 5, a large screen may be realized by combining a plurality of frames 110 with the large frame 200.

This is possible by forming the binding hole 202 at the edge of the large frame 200 and coupling the binding hook 118 of the frame 110 to the binding hole 202.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and those skilled in the art to which the art belongs can make various modifications and other equivalent embodiments therefrom. Will understand.
