Abstract
New fluorescent lamp designs employ Hg-Ar discharges under operating conditions that differ significantly from those found in conventional fluorescent tubes. We have studied the radiant output of Hg-Ar discharges over a wide range of Ar pressure, Hg vapor pressure, and discharge current in test lamps of 5-mm and 23-mm diameter. Radiances for the 185 nm and 254 nm lines of Hg have been determined by direct comparison to a radiometric standard argon miniarc. Radiances for 12 additional lines in the ultraviolet and visible spectrum have been determined with lower accuracy by using the calibrated response of our spectrometer/detector system. These data should be valuable for validation of computer models of Hg-Ar discharges in the regimes important for new lamp designs. We describe the experiment and present representative data.Proceedings Title
