Abstract

Recently, the ultraviolet disinfection is spreading in place of the chlorine sterilization that affects the ecosystem of the downstream in the river. In this paper, the new lighting system of electrodeless discharge lamp for ultraviolet disinfection is proposed, which realized high safety and long life. By developing the method for stably supplying the necessary electric power to the lamp in the case of the low coil voltage, it became possible to extend the life of the discharge lamp, and to improve reliability of the equipment. By experiments, the practicability of the proposed system could be confirmed.
