摘要

In a lighting device having an interior air sterilizing function, and an interior air sterilizing and lighting method according to the present invention, the lighting device senses whether a person is in a room. When the person is not in the room, the lighting device senses emits at least one ultraviolet ray among UV-A (320-360 nm), UV-B (280-320 nm) or UV-C (250-280 nm) to supplied air, discharging the air, and stop emitting illumination light. When the person is in the room, the lighting device stop emitting the ultraviolet ray or emits the ultraviolet ray of UV-A (320-360 nm) to the supplied air to discharge to the outside, emits the illumination light to the room. Therefore, a user is protected and a sterilization effect is maximized because different ultraviolet rays are emitted to the room for sterilization according to the existence of men.
