Lighting device

Abstract

A lighting device includes a light source including at least two types of light emitting elements with different color temperatures, an optical element including a plurality of liquid crystal cells and configured to control a distribution of light emitted from the light source, and a control unit configured to control the light source. The control unit controls the optical element to change from a first light distribution state to a second light distribution state different from the first light distribution state. The control unit controls the light source so that a color temperature of light emitted in a direction perpendicular to a surface of the optical element is the same in the first light distribution state and the second light distribution state.
