Abstract:
1. A method of modulating a light source, the method comprising: providing a hollow tube having a first end with a first endcap and a second end with a second endcap, an inlet valve and a first electrode associated with the first end and an outlet valve and a second electrode associated with the second end; opening the inlet and outlet valves to provide for a simultaneous modification of gases between said first electrode and said second electrode; flowing a portion of a first gas from between said first and second electrodes out of the light source through the outlet valve, and simultaneously flowing a second gas through the inlet valve into between said first and second electrodes, said first gas being different from said second gas; providing power to the first and second electrodes during the flowing of the first and second gases to modulate the light source; and closing the inlet and outlet valves.
