PROBLEM TO BE SOLVED: To provide a lighting fixture capable of attaining long-sideways light distribution and uniformly lighting the whole irradiated surface.SOLUTION: In a floodlight having a floodlight body 6 with a reflecting surface arranged behind a lamp 10 and illuminating the irradiated surface 3 from a position separated from the irradiated surface 3, a long-distance reflecting surface 40 located behind a light-emitting point 36 of the lamp 10 is arranged on the reflecting surface, and a front reflecting surface 41 is arranged on the reflecting surface by continuing to the long-distance reflecting surface 40 in the height direction, a left-side long-distance reflecting surface is arranged at a left side of the long-distance reflecting surface 40 which is divided into left and right sides at the light-emitting point 36 as a border, and a right-side long-distance reflecting surface is arranged at the right side of the long-distance reflecting surface 40. A front range 50 located on the front of the floodlight body 6 on the irradiated surface 3 is illuminated with direct light of the lamp 10 and reflected light of the front reflecting surface 41, the distance from the front range 50 to a left end of the irradiated surface 3 is illuminated with reflected light of the left-side long-distance reflecting surface, and the distance from the front range 50 to a right end of the irradiated surface 3 is illuminated with reflected light of the right-side long-distance reflecting surface 40. |
