Method of an arrangement for introducing dosing material into the envelope of a gas discharge lamp

摘要

A capsule 10 for dosing a lamp, for example for introducing mercury 11 into a discharge lamp, is held by a sheet metal clip 12 with a mounting tag 14 and tabs 13 which embrace the capsule. The clip has a circular hole 22 and is made of ferromagnetic material. Heating of the clip by an electromagnetic field causes the capsule to blow out through the hole 22, releasing the mercury and securing the capsule more firmly to the clip.
