Abstract
A standard bi-pin, non-thermionic fluorescent lamp comprising a fluorescent envelope having a length selected from about two-, four- and eight-foot lengths and a pair of electrode ends, an electrode mounted in the fluorescent envelope at each electrode end, respectively, a pair of rigid conductive mounting pins secured to each electrode end with at least one of the pins being electrically connected to an electrode, respectively. The electrode is selected from tungsten, copper, molybdenum, carbon steel, and a thin film coating on a dielectric substrate. The lamp is driven by a square wave alternating current driver source having a frequency of between about 75 kHz to about 3.9 MHz connected to the pair of electrodes with a preferred frequency of about 100 kHz. In a preferred embodiment, a pair of said non-thermionic lamps are connected in series across the AC square wave driver.
