A device and a method are disclosed for introducing into the fluorescent lamps small amounts of mercury. The device is formed of a metallic container which is capable of containing powders of one or more compounds having the general formula Ti Zr Hg , but is not hermetically sealed, in order to allow the discharge of mercury vapors generated by the decomposition of such compounds. Some possible device geometries are disclosed, as well as some possible arrangements of the same inside lamps. Finally a method is disclosed for introducing mercury into a lamp by means of a device of the invention, without the device remaining in the resulting lamp.

Device for introducing small amounts of mercury into fluorescent lamps

The invention relates to an integrated getter device essentially consisting of at least one evaporable getter device and at least one non-evaporable getter device, wherein the different getter devices circumscribe areas at least partially superimposed or coincident, lying on essentially parallel or coincident planes and preferably arranged in a coaxial way.

Zr-Fe alloys (15%-30% by wt Fe, balance Zr) start to sorb hydrogen at temperatures between 200.degree. and 250.degree. C. They are particularly useful for the sorption of hydrogen within the outer jacket of high intensity discharge lamps.
