1. A lighting device, comprising:
a first reflector that includes: a first hole where a light source is disposed; a second hole that emits light; and a reflection curved surface that connects the first hole and the second hole to each other, in which a line connecting the center of the first hole and the center of the second hole is made to be a first direction, and the first reflector emits light to the first direction;
a liquid crystal lens disposed to cover the second hole of the first reflector; and
a polygonal pyramid including a bottom surface and three or more plurality of inclined surfaces, and being disposed so that the plurality of inclined surfaces oppose the liquid crystal lens, wherein
the plurality of inclined surfaces are reflection surfaces, and on the reflection surfaces, a traveling path of the light traveling to the first direction changes to a second direction, the second direction intersecting the first direction, and
the liquid crystal lens can configure lenses corresponding to the plurality of inclined surfaces.
