Patent abstract
A portable water-purification system includes a container for holding a liquid and an ultraviolet light source configured for immersion in the liquid. The ultraviolet light source is a straight low-cost tube controlled by electronic circuitry for providing hot-cathode striking at a relatively low voltage using a fly-back inductor. The operation of the water purification system is controlled by a micro-controller within the electronic circuitry.
