Ultraviolet lamp with minimized ozone generation

Abstract

This application discloses an ultraviolet lamp with minimized ozone generation, the ultraviolet lamp comprising an outer tube; an inner tube arranged across the interior of the outer tube; an outer electrode installed on the outside wall of the outer tube; and an inner electrode installed on the inner side of the tube; wherein the outer electrode is in surface contact with the outside wall of the outer tube; and the width of the contact surface between the outer electrode and the outer tube is equal to the width of the effective electric field generated between the outer electrode and the inner electrode. Thus, because there is no discharge area between the outer electrode and the outer tube, when the outer electrode is connected to a high voltage, there is no discharge in the air, and no ozone is generated.
