Adjustable ozone delivery system for air disinfection

摘要

An UV light system (10) for treating the air includes an UV tube lamp (20) having a first section (42) for transmitting UV light in a wavelength range thaht includes maximum ozone production and maximum germicidal activity, and a second section (44) for transmitting UV light in a wavelength range thaht includes maximum germical activity while excluding the production of ozone; and a movable annualar sleeve (46) for controlling the amount of ozone transmitted by the lamp (20).
