The present invention relates to an electric signboard, and more particularly, to an electric signboard that can be repaired from the front side by configuring a plurality of electric modules to be detachable from the front.

More specifically, by arranging a plurality of LEDs arranged at regular intervals so that a plurality of modules can be detached from the front side, the light module can be disassembled and assembled from the front side when it is installed in a location where obstacles such as a wall are located on the back side. It is about electric signboard which can be repaired completely.

In other words, it is possible to attach and detach the light module from the front side of the display panel is easy to install in front of the structure is easy to install.

Generally, an electronic sign is used as a predetermined advertisement or display means.

The electric signboard is a means for displaying a desired shape or character by sequentially or selectively emitting light by installing a plurality of light emitting means such as a plurality of LEDs, as shown in FIG. It is configured by detachably installing a plurality of light module 100 installed a plurality of LED on the front of the.

In addition, a predetermined accommodating space is formed in the frame 200 of the signboard, and power supply means for supplying power to the signboard module 100 and power supplied thereto are selectively provided. It is provided with a control means for controlling, the rear surface is configured to block and protect the power supply means and control means to install and repair the power supply means and control means by installing a door.

As described above, the electric sign is configured to tighten the fixing screw 300 in the screw hole formed in the frame constituting the electric module 100, and fixed to the frame.

The electric light module 100 fixed to the frame 200 passes through the holes 210 formed through the fixing screws 300 through the plurality of fixing plates 220 installed in the frame 200 as shown in the electric light module 100. Since the thread formed in the frame of 100 is fixed to the formed screw hole, the fixing screw 300 must be tightened from the back during construction.

In this way, when the display board is installed on the front of the structure such as a wall by fastening the fixing screw 300 to fix the light screw module 100, the installation should be spaced at least a certain distance from the structure so that the worker can enter and exit between the display board and the wall. do.

However, due to the limitation of the installation place, the electric signboard is often installed in close contact with the front surface of the structure such as a wall.In this case, when the structure and the electric signboard are installed in close proximity, there is no space for a worker to enter between the electric signboard and the structure. Some of the modules 100 are damaged, and even when repairing, only the failed electric light module 100 cannot be disassembled, which causes inconvenience in that the entire electronic board must be separated and rebuilt.

In addition, the width of the frame 200 is sufficiently wide to compensate for these disadvantages, and the door can be installed by the operator to the side or the rear, but can be configured, but in this case, the space occupied by the frame is too large construction place There was a problem of being constrained.

In addition, the hood configured in the conventional all-optical module is made of plastic, which not only easily ages, but also reflects light, so that the content displayed by light generated by light emitting means such as an LED cannot be clearly identified.

In addition, the conventional electric signboard has a problem in that the electric sign is malfunctioned because the electric wave is emitted to the outside by the power supplied to the LED constituting the electric sign module or the external electric wave is transferred to the inside.

The present invention has been invented to solve the above problems, by configuring the electric light module to be disassembled and assembled from the front is not only possible to install on the front of the structure, such as the wall, but also to provide an electric sign that can be repaired on the front. It is done.

That is, it is an object of the present invention to provide an electric signboard which is not limited by the installation space because the electric signboard can be constructed in a state close to the front of the structure by configuring the electric sign module to be attached to the front.

In addition, an object of the present invention is to provide a light-emitting plate that can prevent the light of the light emitting means from being blurred by the reflected sunlight by manufacturing the hood from aluminum so that sunlight is not reflected.

A plurality of connection pins are exposed, and these connection pins are coupled to a connector formed on the circuit board 13 so that the circuit board 13 is mounted in the board mounting groove 122.

Since the circuit formed on the circuit board 13 is similar to the circuit used for a conventional electronic board, a detailed description thereof will be omitted. However, these circuit boards are coated with silicon to protect the circuit from moisture.

The through-hole 124 formed in the circuit frame 12 is provided with a reinforcing ring 127 as shown in FIG.

As described above, the electro-optical plate of the present invention tightens the fixing screw 3 from the front surface of the electro-optical module 1 and the end of the fixing screw 3 is tightened to the screw hole 211 of the fixing plate 21 formed in the frame 2. In order to fix the all-optical module 1 to the fixing plate 21, the screw head of the fixing screw 3 should be formed on the all-optical module 1, and the head of the fixing screw is caught. The portion should be formed in the through hole 124 of the circuit frame 12.

However, the circuit frame 12 is made of synthetic resin or the like for the purpose of reducing the insulation or manufacturing cost. If this is made, the through hole 124 is weak in strength and must be reinforced so as to be penetrated by the joining of the fixing screw 3. The fixing screw locking jaw formed in the hole is not damaged by the tightening force of the fixing screw, and the reinforcing ring 127 is installed in the through hole 124 for this purpose.

As shown in FIG. 6, the reinforcing ring 127 is a cylindrical ring, and a screw through hole 127a is formed through the center thereof, and a plurality of key grooves 127b are formed on the outer circumferential surface thereof.

In addition, by manufacturing the hood constituting the all-optical module made of aluminum it is possible to prevent sunlight from being reflected by the hood, and thus the effect of showing a clear sign because the light of the light emitting means is not interfered by the reflected light. There is.

In addition, it is formed in the aluminum hood to form a small LED through-hole through which the LED penetrates or each LED to be penetrated separately so that the silicon installed inside the hood backside is not exposed to the outside, as well as the reflection of light by the silicon By preventing light from being reflected by itself, the light of the LED can be seen more clearly, thereby improving the discriminating power.

In addition, by installing a light blocking plate that blocks sunlight and at the same time prevents distortion of the body plate, it is possible to protect the LED from sunlight or rainwater and to prevent the body plate of the hood from being distorted by heat generated from the LED. By doing so, there is an effect of preventing the electric sign on the display board from being distorted and viewed in a deformed state.

While the present invention has been described with reference to the accompanying drawings, it will be apparent to those skilled in the art that many various obvious modifications are possible without departing from the scope of the invention from this description. Accordingly, the invention can only be construed limited by the words of the appended claims.
