Abstract (en)
[origin: WO8204373A1] Low pressure mercury vapor discharge lamp unit which is constructed to employ a high frequency inverter, have a quiescent time T0? in the range of 0.5 x 10?-6 to 10 x 10?-6, generate a rectangular high frequency AC voltage having a frequency of more than 1kHz, and supply a high frequency voltage to a low pressure vapor discharge lamp sealed with mercury and a rare gas selected so that the ratio X/Y of the molar number Y of the mercury vapor to the molar number X of the rare gas is in the range of 0.5 x 10?2 to 1.0 x 10?4. The moving moire of the lamp is suppressed so as to be reduced or eliminated, thereby largely improving the resonant radiation energy efficiency of the mercury.
