<p>A lighting apparatus lights an irradiation plane (M) with irradiation light projected from a light source (2). The lighting apparatus is provided with reflecting fly-eye optical systems (12, 14), which are arranged between the light source (2) and the irradiation plane (M) and are composed of a plurality of reflecting partial optical systems for performing wavefront splitting to a luminous flux from the light source (2) for superimposition on the irradiation plane (M), and a reflecting optical system (10) arranged between the light source (2) and the reflecting fly-eye optical systems (12, 14) for guiding the irradiation light to the reflecting fly-eye optical systems (12, 14). At least one part of a reflecting plane of the optical system of the reflecting optical system (10) is composed of a diffusing plane.</p> |
