Summary:A mercury dispenser for electric discharge lamps consists of welding a small metallic member (16) in the form of a <>, to a portion of the surface of the cathode disintegration shield (10) and trapping a predetermined volume of mercury under the <>. A dimple (17) may be formed in the shield (10) or in the member (16). The shield (10) may be formed from a continuous strip which is dimpled at a predetermined pitch, the dimples filled with mercury and the <> (16) welded over the dimples. The strip can then be cut into discrete <> sections to be bent into shields and assembled with the cathode structure. The mercury is liberated from unter the <> by heating and vaporisation, the vapour pressure forcing the <> open.
