CONSTITUTION: A guide float using an LED comprises a main body(10), a support frame(20), an auxiliary frame(40), an LED drive unit(100), an LED number indicating unit(200), a lamp, and a protection unit(400). The LED drive unit has a light collector, a charge unit, a controller, and an illumination sensor. The charge unit is connected to the light collector and stores the electrical energy supplied from a solar battery of the light collector. The illumination sensor senses the illuminance of sunlight according to control signals of a controller. The LED number indicating unit is composed of a plate in which numbers are printed, a through-hole, an LED lamp, a convex part for protecting the LED lamp from an external impact or foreign material, and a conductive polymer coating layer which is coated on the top surface of the convex part. |
