BATTERY POWERED UV SANITATION SYSTEM

摘要

An ultraviolet radiation sanitation system which is portable and which operates on battery power to generate UVC radiation to decontaminate bathrooms on aircraft and other small rooms or enclosed areas. The system includes one or more low pressure high output mercury or amalgam UVC lamps mounted on a housing which contains a battery powered power supply, lamp ballasts and control circuitry. The housing also includes a control panel having controls and indicators for system operation. A motion detector is provided on the housing to shut off the system in the presence of detected motion which would occur by the presence of a person. The housing is mounted on a tripod or other stand to support the system on an aircraft bathroom floor or other location in which the system is to be deployed.

主权项

1. A portable battery powered ultraviolet radiation sanitation system for placement in a room to be sanitized, the system comprising:
a portable housing; one or more UVC lamps providing UVC radiation and mounted in vertical orientation on the housing to emit UVC radiation to the room in which the system is placed; a lamp enclosure for the one or more lamps providing mechanical protection of the lamps with no significant shielding of radiation from the one or more lamps into the room; a power source disposed in the housing and having at least one electronic ballast to drive the one or more UVC lamps; at least one battery coupled to the power source; at least one DC-to-DC converter to convert a low battery voltage to a higher voltage sufficient to drive the at least one electronic ballast; an electronic controller to control operation of the system including monitoring the current to the at least one electronic ballast, comparing the value with a predetermined value and turning off the system if the current is less than the predetermined value; and at least one motion detector to turn off the UVC lamps in the event motion is detected in the vicinity of the lamps.
