Abstract

Some mercury behaviors in a compact fluorescent lamp with amalgam have been analyzed. The discharge tube is doubly folded. The main amalgam is contained in an exhaust tube and auxiliary amalgams are near the electrodes.<BR>The results are as follow.<BR>(1) The amount of In coating on the auxiliary amalgam flag influences luminous build-up characteristics of the lamp.<BR>(2) After switching the lamp off, its mercury vapor diffuses from main amalgam to auxiliary amalgams.<BR>(3) The mercury weight in auxiliary amalgam increases in proportion to the square root of T (T; total time lapse after switching off).<BR>(4) The lamps mercury vapor pressure becomes minimum around forty cinutes after switching the lamp off.
