1. A smart air-surface sterilization system, comprising:
a human body detection sensor to determine an occupied situation or an empty situation of an indoor space;
a lifting member installed in the indoor space;
a lifting module to vertically lift the lifting member up and down;
a folding module installed on the lifting member, wherein the folding module is folded when the lifting member is lifted up and is unfolded when the lifting member is lifted down; and
a Ultra-Violet C (UVC) lamp installed in the folding module,
wherein when the empty situation is determined, the lifting member is lifted down by the lifting module, the folding module is unfolded, and the UVC lamp emits UVC radiation to a wall of the indoor space to perform surface sterilization, and
when the occupied situation is determined, the lifting member is lifted up by the lifting module, the folding module is folded, and the UVC lamp faces a ceiling surface of the indoor space, and emits UVC radiation into air flowing between an upper surface of the lifting member and the ceiling surface of the indoor space to perform air sterilization; and
wherein the lifting member is a plate member which faces a bottom surface of the indoor space,
wherein the smart air-surface sterilization system further comprises a ceiling installation member, wherein the ceiling installation member faces the lifting member and is integrally fixed and installed at the ceiling surface of the indoor space,
wherein the folding module includes first and second lamp installation members, wherein the first and second lamp installation members are elongated members, and are rotatably connected to each other by an intermediate hinge,
wherein an upper end of the first lamp installation member is rotatably coupled to a lower surface of the ceiling installation member,
wherein a lower end of the second lamp installation member is rotatably coupled to the upper surface of the lifting member, and
wherein the UVC lamp is installed in each of the first and second lamp installation members.
