A method for manufacturing a signboard equipped with a light emitting diode is provided to reduce the weight of a sign board by a third and thickness over a half by removing the need of a safety apparatus and a start lamp and to make the signboard 10 times as bright as a fluorescent lamp. A signboard equipped with a light emitting diode(4) is composed of an inner frame(1); a flat panel(2) for installation of the light emitting diode; a light emitting diode case(3) installed on the flat panel; the light emitting diode mounted in the light emitting diode case; an electric wire(5) for supply of power; and an outer frame equipped with an advertisement character display board to display an advertisement message and assembled with the inner frame. |
