Abstract: A sanitizing UV lamp device for disinfecting surfaces in spaces used by people, including a motor vehicle cabin, includes a housing having a cup shaped base, UV lamps powered for a selected period of time by the control circuit, a reflector, and a protective screen surrounding the reflector and the UV lamps to provide 360-degree germicidal irradiation through openings defined by the screen. The UV lamp device also includes various safety features, including occupancy detection to prevent irradiation from the at least one UV lamp upon detection of motion.
