Abstract

PURPOSE:To obtain high efficiency without damaging rapid start chracteristic by enclosing the mixed rare gas as starting gas which contains a specific amount of Xe, and Ne and Ar as the rest, in a bulb and has the ratio of Ar less than a specific amount of Ne. CONSTITUTION:Into the bulf of a fluorescent lamp, the mixed rare gas which contains 10-40% by volume of Xe, and Ne and Ar as the rest and has the ratio of Ar in 3% or less of Ne is enclosed as starting gas with a proper amount of mercury. When the ratio of Xe in the enclosed gas exceeds 40%, the lamp impedance decreases and the lamp current increases, and a stabilizer having rated value cannot withstand the current, and also the optical output of the lamp decreases. When the ratio of Xe is less than 10%, the consumption of electrode is remarkable, and the life of lamp is shortened. By keeping the ratio at a level described above, high efficiency can be obtained without deteriorating rapid starting characteristic.
