Abstract

PURPOSE:To enable input electric power used for a device to be saved, and decrease the temperature rise of the ballast of the device by charging a rare gas, argon, in a fluorescent lamp at below a given pressure, and by burning the lamp by the combination of the lamp and a condensive ballast. CONSTITUTION:The inner wall of a glass bulb 3 of a fluorescent lamp 2, which is charged with argon at a pressure of below 1.3 Torr, is coated with both a phosphor film 4 and a nesa film 7. An electrode 5 is fused to each end of the glass bulb 3 within the bulb 3. Burning of the lamp 2 is carried out by the combination of the lamp 2 and a condensive ballast. As a result, the mean free path of electrons within the lamp 2 is lengthened, recombination of electrons and ions on the wall of the tube 3 is enhanced, the slippage in waveform between the lamp current and the lamp voltage is increased, and thereby the power factor is reduced and electric power used for the lamp 2 can be decreased. Besides, the use of the condensive ballast prevents the loss of electric power consumed by the ballast from being increased, and input electric power used for the ballast can be saved.
