抄録

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. The results are as follow. (1) The amount of In coating on the auxiliary amalgam flag influences luminous build-up characteristics of the lamp. (2) After switching the lamp off, its mercury vapor diffuses from main amalgam to auxiliary amalgams. (3) The mercury weight in auxiliary amalgam increases in proportion to the square root of T (T; total time lapse after switching off). (4) The lamps mercury vapor pressure becomes minimum around forty cinutes after switching the lamp off.
