Abstract (en)
In an arc tube fabricating process an oxygen-absorbing getter is affixed to at least one (29) of a pair of electrodes (29, 31), one of the electrodes (31) is sealed into the end of a tubular ceramic envelope (27), a dosage is deposited in the tubular ceramic envelope and the other one (29) of the pair of electrodes is sealed into the other end of the tubular ceramic envelope.
