There is provided a lighting system simple in configuration and capable of irradiating an irradiation image with less distortion onto an irradiation surface. For this reason, light shielding masks 24 causing light from an LED 12 to be incident on lens units 23b are arranged oppositely to a fly-eye lens 23. The opening shape of a light shielding unit 24b arranged on the light shielding mask 24 is set according to the state where the fly-eye lens 23 opposes an irradiation surface 100, and the light shielding unit 24b prohibits light in a range distorting the shape of an irradiation image on the irradiation surface 100 from being incident on the lens units 23b.
