Disclosed is a light device comprising: a diffusion unit for diffusing and radiating light incident from a light source; and a condensing unit installed on a light radiating surface of the diffusion unit, including a micro lens array of lenses having sag determined depending on one of a light emitting area of the lighting device and total light flux of the lighting device. Thus, the lighting device can reduce a light flux emitted at the angle between 65 deg and 90 deg, thereby meeting UGR conditions.
