Abstract
A movable LED lamp that emits in the UV wavelength for germicidal purposes. The LED lamp can be mounted near the ceiling such that air in a room can be disinfected. Movements of the LED lamp sweeps the air near the ceiling in ultraviolet germicidal irradiation, which kills both bacteria, virus, fungi, and other bioaerosols. A poorly ventilated room can be disinfected more readily with such a sweeping system.
