摘要

References(14) Ballast-integrated compact fluorescent lamps are widely used for replacing incandescent lamps as energy saving alternative light sources. In spite of their high efficacies, the luminous run-up characteristics of the lamps having outer globes are slow and rather unsatisfactory, especially within a second or two. This problem is due to the lower mercury vapor pressure PHg of amalgam dosed in the discharge tube than that of liquid mercury. In order to improve the luminous flux at starting the lamp ignition, the PHg changes in the discharge tubes including bismuth-indium main amalgam and indium auxiliary amalgam were studied during switch-off period by atomic absorption spectrometry using 254 nm line. The amounts of mercury absorbed in both the main and auxiliary amalgam were also measured by wet chemical analyses. It is found that the PHg during switch-off period is not controlled by only the auxiliary amalgam but also the main amalgam.
