ABSTRACT:
A low-pressure mercury vapor discharge lamp includes a discharge vessel having two end portions. An electrode carrier is arranged in an end portion and carries an electrode for generating and maintaining a discharge in the discharge vessel. The electrode carrier is at least partly made of a bimetal or a memory metal, and is formed such that the distance between electrode and the far end of the end portion increases if the temperature of electrode carrier increases.
