Abstract

PURPOSE: To lengthen the service life of discharging lamp, by providing processes for increasing/decreasing the gas pressure, for storing the gas, for filling the bulb with gas, then after evacuating the air-tight system leading the gas having increased/ decreased pressure into gas resorvior to minimize the mixing of impurity due to minute leak.
CONSTITUTION: Reducing valve 6 comprising valve body 4 and outlet valve 5 is fixed to the plug 3 of gas cylinder 1, then connected through a valve 7 to gas resorvior 8 and the gas is supplied from said gas resorvior 8 through valve 9 toward bulb. Vacuum system 12 comprising valve 10 and vacuum pump 11 is employed as means for evacuating the air tight system from gas cylinder plug 3 to valve 9 and the gas resorvior 8. Consequently when filling the bulb with gas, the mixing of impurity due to minute leak is minimized resulting in the lengthening of service life.
