In addition, since the LED module 10 is screw-coupled to each frame of the perforated frame 24, there is an advantage in that each of the LED modules 10 can be easily replaced.

Next, the fixed substrate 30 is coupled to the LED substrate 20, and serves to fix the electric sign to the exterior wall of the building.

In addition, the fixed substrate 30 is formed as an empty space therein, so that the controller 14 and the power supply unit 16 provided on the rear surface of the LED module 10 are stored.

In addition, the fixed substrate 30 may be provided with a traction ring 38 at the upper end, and by connecting a sling belt to the traction ring 38 to move the electric sign board with a crane, the electric sign board is more easily installed on the outer wall of the building can be installed on

For example, when the fixed substrate 30 is installed on an outer wall of a building, only a fixed bracket is installed on the outer wall of the building to fix the fixed substrate 30 to the fixed bracket, and the fixed substrate 30 is fixed to the outer wall of the building. By doing so, since a separate structure is not required, the electric signboard can be easily installed.

That is, the front openable electric signboard for outdoor use according to the embodiment of the present invention is manufactured by structuralizing the electric sign itself, so that when installed on the exterior wall of a building, the electric signboard is fixed to the exterior wall of the building by using only a fixing bracket without installing a separate structure.

At this time, the outlet 34 further includes a blower fan 33 to move the air introduced through the inlet 32 in one direction to discharge the heat generated inside the sign to the outside of the sign. do.

Specifically, the blowing fan 33 moves the air introduced through the inlet 32 in the direction of the outlet 34, so that the air and heat present in the electric sign are discharged through the outlet 34, , so that the heat generated inside the electric sign by the LED module 10 and the air introduced through the inlet 32 are mixed, so that the internal temperature of the electric sign is lowered.

In addition, the inlet 32 and the outlet 34 may be additionally provided with a cover 35 having one side open to allow air or heat to flow to one side in front.

For example, it is preferable that the lower side of the cover 35 is opened, but any one of the other side surfaces other than the upper side may be formed open.

That is, the cover 35 is formed with an open lower side, so that external air flows into the lower side of the inlet 32, and the air introduced through the inlet 32 to the lower side of the outlet 34 and the electric sign are generated. to allow the heat to be dissipated.

In addition, the cover 35 is installed in front of the inlet 32 and the outlet 34 to prevent foreign substances such as rainwater, fallen leaves, and dust from entering the inside of the electric sign board.

Therefore, since the LED board 20 is separated from the fixed board 30 and can be opened and closed, the operator enters between the electronic sign board and the outer wall of the building during maintenance work such as replacing the LED module 10 and replacing parts. It is possible to maintain the electric sign board more easily by opening and closing the front of the fixed board without the need for dangerous work.

At this time, a support member 50 may be provided between the LED substrate 20 and the fixed substrate 30 in order for the operator to safely maintain the inside of the electric sign board.

The support member 50 allows the LED substrate 20 to be easily opened and closed, and the LED substrate 20 is separated from the fixed substrate 30 to fix the LED substrate 20 in a rotated state. plays a supporting role.

Preferably, the support member 50 may be an industrial gas shock absorber, but is not limited thereto.

That is, the support member 50 is separated from the fixed substrate 30 and supports the rotated LED substrate 20, so that during repair work inside the electric sign board, the LED substrate 20 is fixed and the operator is more so that you can work safely.

As shown in FIG. 5 , the electric sign board may be provided with a contact means, and the adhesion means makes the LED substrate and the fixed substrate in close contact, so that external moisture or water does not enter the electric sign board. do.

Preferably, the contact means is recessed by a predetermined depth to correspond to the coupling protrusion 36 formed along the inner side edge of the fixed substrate 30 and the coupling protrusion 36 along the inner side edge of the LED substrate 20 . The formed coupling groove 26 may be provided.

For example, the coupling protrusion 36 and the coupling groove 26 are preferably formed in a semicircular shape, but as another example, they are formed in a rectangular shape, but may be formed in multiple stages.

At this time, the shape of the coupling protrusion 36 and the coupling groove 26 is not limited, and the positions of the coupling protrusion 36 and the coupling groove 26 are also the fixed substrate 30 and the LED substrate 20 . ) can be changed between

That is, in the electric sign board, the LED substrate 20 and the fixed substrate 30 are connected by a hinge 40 , and a coupling protrusion 36 formed on the fixed substrate 30 is coupled to the LED substrate 20 . It is inserted into the groove 26 to prevent moisture or water from entering the inside of the electric sign board.

At this time, a rubber packing member (not shown) may be provided along the outer circumferential surface on either side of the coupling protrusion 36 or the coupling groove 26, and the coupling protrusion 36 may be provided by the rubber packing member (not shown). is fitted into the coupling groove 26, so that the fixed substrate 30 and the LED substrate 20 are more closely coupled to further prevent external water or moisture from entering the inside of the electric sign board.
