| 摘要 |
A low-voltage ballast-free energy-efficient ultra-violet material treatment and purification system and method having an ultraviolet (UV) source comprising a gas discharge UV lamp (12) having spaced electrodes (16, 17), a source of a low-voltage, high-frequency alternating current square wave voltage (20) and connected directly to the spaced electrodes to non- thermionically excite the gas discharge UV lamp (12). A flow sensor (26) is used to proportionately control the intensity of UV generation as a function of flow rate.
