ELECTRODELESS FLUORESCENT LAMP, ELECTRODELESS SELF-BALLASTED COMPACT FLUORESCENT LAMP, AND LIGHTING DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a small electrodeless fluorescent lamp and an electrodeless self-ballasted compact fluorescent lamp with improved light flux build-up characteristics right after lighting, and a lighting device equipped with these. PSOLUTION: Since a main amalgam with high mercury vapor pressure is used, the mercury vapor pressure inside the fluorescent lamp can be made comparatively high even at normal temperature, and the light flux build-up characteristics can be further improved by arranging a gold auxiliary amalgam which does allow the mercury to be absorbed so much as to lower the vapor pressure inside a tube during switching off of light.
