PURPOSE: An advertising board flood light is provided to improve an advertising effect by adjusting the installation number of an LED according to the angle and the location of a module plate and uniformly irradiating light in the upper, the middle, and the lower part of an advertising board, and clearly recognizing the advertising board in the long distance. CONSTITUTION: A module plate(20) comprises a first irradiator(23) which slops upward to irradiate light upward from an LED(21) in the lower part, a second irradiator(25) which slops downward to irradiate light downward in the upper part of the first irradiator, a third irradiator(27) which slops upward to irradiate light upward in the upper part of the second irradiator. The LED is arranged by increasing the number of the LED in the second irradiator and the third irradiator more than the number of the LED in the first irradiator. An protrusion piece(32) is perpendicularly projected in the edge of a hit sink(30) at a regular length. A space portion(34) is formed to arrange a module plate(20) inside the hit sink. A strengthening glass panel is formed in the end part of the protrusion piece to cover up the space portion and separate with the outside. A panel cover(36), which is connected with the end part of the protrusion piece(32) in the middle of a rubber packing(52), is formed in the edge of the strengthening glass panel. |
