1. A lighting system of an air mobility including a boom and a propeller provided on the boom, the lighting system comprising:
the boom and the propeller;
a light emitting unit provided on the boom or the propeller of the air mobility and configured to emit light toward a ground surface so that the light is projected onto a point directed toward the ground surface from the propeller or the boom; and
a control unit electrically connected to the light emitting unit and configured to control light emitting modes for emitting the light from the light emitting unit according to operating modes of the propeller,
wherein a shape of the light projected onto the ground surface by the light emitting unit is a circle formed when the propeller rotates,
wherein the operating modes of the propeller include a standby mode and a driving mode, and the light emitting unit changes colors, brightness, shapes, or light emitting periods of the light emitted according to the operating modes of the propeller so that the operating modes of the propeller are distinguished from the outside of the air mobility.
