Electronic sign with waterproof structure {MESSAGE SIGN APPARATUS WITH WATERPROOFING STRUCTURE}

The present invention relates to an all-optical signboard having a waterproof structure, and more particularly, to prevent the inflow of water into the gap between the connection portion of the LED module assembly installed in the enclosure, and to allow the water to drain smoothly even if the water flows into the malfunction of the LED module. It relates to an all-optical sign having a waterproof structure to prevent this and improve durability.

In general, various display devices such as advertising signs, guide signs, traffic signs, and the like are displayed on the display body of a plate by a method of printing or the like.

Such display devices are capable of sufficient identification in clear weather or daytime, but when the weather conditions are not good, such as at night, in rainy weather, or in the fog, the identification power is significantly lowered, and thus, the function of the guide plate may not be properly performed. In particular, the traffic sign has a disadvantage in that it can not secure a smooth traffic flow and cause serious traffic accidents when the discrimination power falls.

In addition, the display device needs to modify the displayed character or figure according to a change of information or a situation to be expressed. In particular, traffic signs need to actively provide traffic information and road information in accordance with road conditions and weather conditions.

Accordingly, as shown in the Republic of Korea Utility Model Registration No. 20-0400256, Republic of Korea Utility Model Registration No. 20-0292860, an electronic signboard with an LED module is disclosed.

For example, the all-optical sign plate 100 having the built-in LED module has a housing 110 formed therein as shown in FIG. 1 and installed in a support (not shown), and a plurality of installed at the front of the housing 110. The LED module assembly 120 is composed of.

Enclosure 110 is a border plate 111 formed in a substantially rectangular frame shape, the back plate 112 formed in the rear of the border plate 111, and the LED module assembly 120 in front of the border plate 111. Is provided with a grid-shaped module installation frame 113 is installed.
