Abstract
A two-dimensional area tilted illumination system has a long light source for emitting a light flux and a reflecting mirror having a generating line generally parallel to a longitudinal axis of the light source. A surface of the reflecting mirror has a first area for illuminating an illumination area after the light flux is first reflected and converged. The first area is shaped such that an intersection point of the light rays, reflected at two ends of the first area, is a position which results in the light rays impinging a center of the illumination area.
