1. A lighting apparatus including a plurality of modules, each of which includes:
a light source unit of emitting light;
a first reflection unit of reflecting the light incident from the light source unit to discharge the reflected light outside the first reflection unit;
a second reflection unit rotatably mounted between the light source unit and the first reflection unit to reflect light and configured for allowing the light emitted by the light source unit to move to the first reflection unit or blocking the light such that the light is not moved to the first reflection unit and reflecting the light at a position different from the first reflection unit to discharge the light outside the second reflection unit depending on a rotational position of the second reflection unit; and
a driving unit connected to the second reflection unit and configured of adjusting the rotational position of the second reflection unit,
wherein the second reflection unit is mounted to be rotatable in an axis,
wherein a first side of the second reflection unit configured for reflecting light with the first reflection unit is provided at a first side of the axis,
wherein a second side of the second reflection unit configured for reflecting light while blocking light moving to the first reflection unit is provided at a second side of the axis,
wherein the first reflection unit is formed to have a curvature,
wherein the first side of the second reflection unit is formed to have a curvature identical to the curvature of the first reflection unit, the first side of the second reflection unit forming a curved surface with the first reflection unit while the first side of the second reflection unit is located to face outside, and
wherein the plurality of driving units of the plurality of modules are connected to each other via a connection unit such that rotational positions of the second reflection units are simultaneously adjusted when one of the plurality of driving units is operated.
