PURPOSE: An advertisement panel is provided to entirely secure uniform brightness by recompensing brightness variation at the connection part of a fluorescent lamp when manufacturing a large advertisement panel. CONSTITUTION: An advertisement panel is composed of a fixing frame(1), a lighting reflection plate, a lighting part(10), and a brightness control member(35). The fixing frame forms an external frame for installation of an installation. The lighting reflection plate is installed in the fixing frame. One and more external electrode fluorescent lamps are arranged in a row to a longitudinal direction in the lighting part. The external electrode fluorescent lamps are overlapped to a lateral direction on the external electrode fluorescent lamps which are arranged in a row. The brightness control member is installed in the connection part and recompenses brightness variation by reducing the quantity of light which is emitted from the connection part. |
