This lighting system includes a lighting device (2) and an illumination-condition setting unit (402). The lighting device (2) has a light-emitting unit comprising a plurality of light-source units that are provided so as to illuminate, in accordance with independently-adjustable illumination conditions, a plurality of illumination sectors, respectively, in a prescribed illumination area on a road surface. The illumination-condition setting unit (402) sets the illumination conditions for the light-emitting unit on the basis of state information that is obtained for each illumination sector and indicates the state of the road surface or vehicles driving thereon.
