Abstract

This invention relates to a disinfection device comprising a housing for receiving a plurality of light emitting diode (LED) units capable of emitting radiation for disinfection, the housing having an internal surface coated with a light reflective material, the internal surface arranged to reflect radiation emitted from each of the LED units; wherein each of the plurality of LED units comprises a corresponding lens unit arranged to focus or collimate radiation emitted by the LED unit. A system for disinfection of an enclosed area comprising a plurality of the disinfection device, an air disinfection device in the form of a collimator, and a processor configured to toggle each of the plurality of LED units between an off state and an on state is also provided. A method for providing disinfection to an enclosed area having walls and a ceiling using the disinfection device is also provided.
