PURPOSE: An air signboard having an LED module is provided to increase a reaction speed, to reduce power consumption, to enhance a lifetime and to enable implementation of various colors by using the LED module as an internal light emitting unit. CONSTITUTION: An air signboard(100) having an LED includes an air tube(110), a prop(120), a blower(130), a light emitting unit and a power supply unit(150). The air tube is expanded or contracted to have a predetermined shape by pressure of air injected by the blower. A lower part of the air tube is closely attached to an upper part of the prop. The blower for injecting air into the air tube is prepared. The light-emitting unit is fixed to a fixing unit(111) arranged on the top of the air tube and the other end is connected to the power supply unit. |
