COMPACT SELF-BALLASTED FLUORESCENT LAMP

摘要

PROBLEM TO BE SOLVED: To improve light flux stability at lighting operation without degrading light flux build up characteristics at start-up. SOLUTION: Composition of main amalgam to be sealed inside a luminous tube is decided so that reaction ending temperature when the main amalgam changes from solid phase to liquid phase is lower than ambient temperature of the main amalgam at lighting operation of the bulb type fluorescent lamp.
