Therefore, there is a problem that it is difficult to identify numbers from a distance due to poor condensing and straightness of light.Especially during sea fog or rainfall, light collides with water particles and scatters or is absorbed by water particles, which significantly decreases the visibility of the numeric keypad. There is a problem in that it is difficult to anchor the ship at the gate of the desired pier during rain or sea.

In addition, since the above-described prior art LED number display means 200 displays a number by arranging a plurality of LED light-emitting means very closely, the number of LED light-emitting means is required to increase installation cost, and also LED light-emitting means There is a problem that the operating heat of the LED light emitting means is not easily discharged because they are densely arranged.

In addition, during the daytime when sunlight is intensely exposed due to clear days, both direct sunlight irradiated from the sun and reflected light reflected from the surrounding seawater are split by the LED number display means 200 installed on the outer surface of the support frame 20 of the prior art buoy. As a result, the LED number display means 200 is heated to a very high temperature, and there is a problem that the LED number display means 200 is overheated and a failure occurs.
