(54) | Improved getter for incandescent lamps |
(57) This invention relates to incandescent lamps and more particularly to the gettering
of such lamps. In accordance with the present invention there is provided an improved
method of gettering an incandescent lamp. The method comprises introducing a fill
gas and a getter compound comprising a silane compound, or a partially halogenated
derivative thereof, into an unsealed lamp envelope; sealing the lamp envelope; and
heating the sealed envelope, for a sufficient period of time, and at a temperature
sufficient to activate the getter to perform its desired gettering function prior
to the thermal decomposition thereof. |
