Abstract

See full text

A lighting device includes a plurality of lighting modules and a plurality of control devices. The lighting modules each includes a plurality of light emitting devices aligned in an array form or a staggered form. The control devices are configured to adjust light quantities of the light emitting devices of each of the lighting modules so that, when light is irradiated on a first target surface separated by a prescribed distance from the lighting modules, a sum of light quantities per unit area of a part for which light from the lighting modules overlaps in the first target surface is within ±20% with respect to a light quantity per unit area of a part for which light does not overlap in the first target surface.
