LIGHTING DEVICE

摘要

According to the present embodiment, a lighting device comprises a light source (20), and at least one light distribution control member (10) for controlling the distribution of light from the light source. The light distribution control member has two optical control layers (2a, 2b) disposed facing each other across a predetermined gap and sandwiching a base material (5) having a higher refractive index than air, and the two optical control layers have first areas (3) and second areas (4) formed in patterns that correspond to each other. The light distribution control member controls light distribution by using the change in overlap between the first areas and the second areas, depending on the direction of light passing through.
